DIMENSIONS in 9i Standard Edition

[Alexandre Gorbatchev]

Hello guys,

Does anybody know if I can use dimensions in Oracle 9.0.1 SE? Namely CREATE
DIMENSION?
I'm getting ORA-00439: feature not enabled: Materialized view rewrite.
Does this feature present only in EE?

Tia,
Alexandre

RE: Re-creating control files with larger maxdatafile setting

[Vikas Khanna]

KG, 

It will not help just by increasing the db_files parameter in the Init.ora
file. Whenever you need to change MAXDATAFILES,MAXLOGFILES,MAXLOGMEMBERS for
your database the change is to recreate the control file and then mount and
open the database.

What needs to be done is : 

Svrmgr> Alter database backup controlfile to TRACE;
This would generate an ASCII text based file at the location defined by
USE_DUMP_DEST in your init.ora. Edit that file in any text editor and chane
the Value of MAXDATAFILES (in your case). Save the file with some name at a
particular destination.eg C:\Controlfile\Control.Sql

SVRMGR> Shutdown immediate;
Instance Shutdown.
SVRMGR>Startup Nomount;
Instance Started. 
SVRMGR>@C:\Controlfile\Control.Sql;
Statement Processed.
SVRMGR> Alter database mount;
Database Mounted.
Svrmgr> Alter database open;
Database opened.

Now you can create the new datafiles to expand your database. Never the
parameter db_files can be more that the MADATAFILES declared in your
controlfile;

Thanks

If you want to recreate the controlfile **just to **
increase the max datafiles, you can simply increase
the db_files parameter and bounce the database. This
will automatically chance the max datafiles settings
when you create the additional datafiles.

RE: Re-creating control files with larger maxdatafile setting

[Naveen Nahata]

KG,

you cannot increase the db_files parameters beyond the MAXDATALIFLES number.
Oracle reserves space for storing the info about individual datafiles in the
control files depending upon the MAXDATAFILES.

To increase the number of datafiles beyond this limit, you have to recreate
the Control file.

TO create a control file, do a ALTER DATABASE BACKUP CONTROLFILE TO TRACE,
which will create a script file to recreate the control file. You can edit
that file and increase the MAXDATAFILES and then recreate the controlfile
using the script file

Regards
Naveen

Usage and Event 10046

 



I spent last two
days working on that SQR and finally nailed it. Developers were using DISTINCT
as a rule and CBO was choosing incorrect indexes. 





 





I had to do
following to make it work ...





 





1. we put
hints in appropriate places





2. created 3
new indexes to help the queries





3. Created 1 MV





4. Change the
pl/sql code to be more efficient





5. Remove
unnecessary distinct conditions.





 





After all this
said and done, I finally have the SQR taking around 375 seconds compared to
about 1500 seconds. Even if I run all 8 of them in parallel it doesn't blow the
TEMP segments.





 





Now comes the
difficult part, to explain the development the things that we had to do and why
we had to do them.





 





I think I am
really starting to see the power of event 10046 ... I just wish I should learn
more on event 10053 as well, but that will come too eventually.





 





I am still going
to track the temp segment usage though ...





 





Thanks everyone
for all your kind suggestions, I am not done yet, there is more work to be
done.

Hi.

A developer of mine is running a large insert as
select:

insert /* parallel hint */ into table A 
nologging 
(select * from table b where ...);

There are no indices on table A and a PK disabled.
Still that insert generates a large amount of logs.
What could be the reason for that? Any ideas? Table A
is not partitioned and has NOLOGGING attribute on the
dba_tables set to Yes.

RMAN implementation strategy

[O'Neill, Sean]

Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by
extenstion also as part of our DR solution.  I've been trying to locate
information on how best to configure RMAN across our organisation.  

For example it's advised you place catalog on separate server to production
server.  So server A might house catalog for server B and vice versa.  But
in a DR scenario where both servers could be destroyed there are I 'suspect'
potential implementations on overall MTTR depending on configuration.  Is it
then perhaps better to locate all catalogs on a dedicated server which
ideally would be replicated somehow to eliminate it as a singal point of
failure.

Also we have a requirment to be able to potentially recover data as far back
as 7 years.  These are currently comprised of monthly backups taken out of
regular cycle and archived off site.  I'm thinking it might be an idea to
set up a two catalogs, one for regular monthly cycle and another to record
these monthly archives as the maintenace of the catalog might be cumbersome
trying to ensure the montlhy archive data records do not get accidentally
deleted.

I've had a trawl across the Web courtesy of Google but did not find any
papers which appear to deal with these type of issues.  The RMAN User's
Guide and Reference does not appear to address them either.  Your
feedback/comments or references to papers would be much appeciated!.

If you want to recreate the controlfile **just to **
increase the max datafiles, you can simply increase
the db_files parameter and bounce the database. This
will automatically chance the max datafiles settings

Title: HELP! CAN't STARTUP REMOTE DATABASE USING SQL*PLUS - BUG?-NADA on METASTINK



Hello
 
I noticed that your sqlplus logon connects to an idle 
instance.
That's mean that you are NOT connected to the 
remote database.
You need to set oracle_sid or use connect 
system/password@database.
 
Also why not do shutdown immediate instead of 
abort?

RE: Re-creating control files with larger maxdatafile setting

[K Gopalakrishnan]

Not sure from which manual it is mentioned. In any case
the manual is incorrect for Oracle8 and above  versions.
You **CAN** create the datafiles than MAXDATAFILES
if you have specified db_files parameter greater than
the MAXDATAFILES.

You may want to file a Documentation BUG on that Manual.

It will not help just by increasing the db_files parameter in the Init.ora

your database the change is to recreate the control file and then mount and
open the database.

What needs to be done is :

Svrmgr> Alter database backup controlfile to TRACE;
This would generate an ASCII text based file at the location defined by
USE_DUMP_DEST in your init.ora. Edit that file in any text editor and chane
the Value of MAXDATAFILES (in your case). Save the file with some name at a
particular destination.eg C:\Controlfile\Control.Sql

[K Gopalakrishnan]

THis one is from  pg 876 of Oracle9i SQL Reference
PArt # A90125-01


*BEGIN QUOTE
MAXDATAFILES Clause
Specify the initial sizing of the datafiles section of the control file at
CREATE
DATABASE or CREATE CONTROLFILE time. An attempt to add a file whose number
is greater than MAXDATAFILES, but less than or equal to DB_FILES, causes the
control file to expand automatically so that the datafiles section can

The number of datafiles accessible to your instance is also limited by the

So it is clear that you can add datafiles to the database without
recreating the control files as long as the db_files are specified
to higher number.

RE: Lost ofall redo logs

[Bill Buchan]

If you lost the redo logs *after* you shutdown the database, you can do the 
following to re-create them:


1. As DBA: startup mount;

2. alter database backup controlfile to trace;

3. select * from v$controlfile;

4. shutdown

5. Delete the controlfiles identified by (3) as these need to be re-created.

6. Edit the tracefile created by (2) to look something like the following:


STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "SID" RESETLOGS NOARCHIVELOG
 MAXLOGFILES 6
 MAXLOGMEMBERS 2
 MAXDATAFILES 64
 MAXINSTANCES 1
 MAXLOGHISTORY 226
LOGFILE
   GROUP 1 '/usr4/oradata/SID/redoSID01a.log'  SIZE 50M,
   GROUP 2 '/usr4/oradata/SID/redoSID02a.log'  SIZE 50M,
   GROUP 3 '/usr4/oradata/SID/redoSID03a.log'  SIZE 50M,
   GROUP 4 '/usr4/oradata/SID/redoSID04a.log'  SIZE 50M
DATAFILE
   '/usr1/oradata/SID/system_01.dbf',
   '/usr2/oradata/SID/users_01.dbf',
   '/usr3/oradata/SID/users_indexes_01.dbf',
   '/usr3/oradata/SID/rollback_01.dbf'
CHARACTER SET WE8ISO8859P1
;
ALTER DATABASE OPEN RESETLOGS;
ALTER TABLESPACE TEMP ADD TEMPFILE '/usr1/oradata/SID/temp_01.dbf' REUSE;


ie.

i.  Remove leading comments and lines beginning with #
ii. In the CREATE CONTROLFILE line change REUSE to SET
and NORESETLOGS to RESETLOGS
iii.Get rid of RECOVER DATABASE
iv. Change ALTER DATABASE OPEN to ALTER DATABASE OPEN RESETLOGS
(v. Ignore ALTER TABLESPACE stuff if you are not using LMT
temporary tablespaces.)

7. Now go into SQL*Plus as DBA and run the script, which should build new
controlfiles, re-create the log files and open the database.


Remember to back up everything you *do* have before starting.  This will 
not work if you lost the redo logs before you shutdown the database.

- Bill.

Well, point taken. I'll try and test it too when I get time.

My point came from the DB Reference Guide, 9i Release 2. You can also see the
same point in the SQL Reference in ALTER SYSTEM command. Maybe it is

If a media failure damages all members of an online redo log group, then 
different scenarios can occur depending on the type of online redo log 
group affected by the failure and the archiving mode of the database.

If the damaged log group is inactive, then it is not needed for crash 
recovery; if it is active, then it is needed for crash recovery.

*If the group is . . .* *Then . . .* *And you should . . .*

Inactive

It is not needed for crash recovery

Clear the archived or unarchived group.

Active

It is needed for crash recovery

Attempt to issue a checkpoint and clear the log; if impossible, then you 
must restore a backup and perform incomplete recovery up to the most 
recent available log.

Current

It is the log that Oracle is currently writing to

Attempt to clear the log; if impossible, then you must restore a backup 
and perform incomplete recovery up to the most recent available log.

Your first task is to determine whether the damaged group is active or 
inactive.


*Loss of Multiple Redo Log Groups*

If you have lost multiple groups of the online redo log, then use the 
recovery method for the most difficult log to recover. The order of 
difficulty, from most difficult to least difficult, follows:

   1. The current online redo log
   2. An active online redo log
   3. An unarchived online redo log
   4. An inactive online redo log

Re: Index question

[Alexandre Gorbatchev]

I think it's not possible. Query will lock an index in some way, so you
cannot drop it until query releases it because DDL will not be able to
accure exclusive lock on the index.
I'm not sure when query releases index lock. I would say at the end of a
query but may be wrong.

Re: Lost ofall redo logs

KG, doesn't anyone think not having a backup is a bad thing.

You can go down that route if you wish but as I remember undocumented

Re: RMAN implementation strategy

[Jay Hostetter]

Sean,

  I wasn't able to put our catalog database on another server, so after backups I 
export the catalog database and ftp the .dmp file to another machine.
  As far as the 7 year requirement, can you export the relevant data and save the .dmp 
file on tape for 7 years?  Your biggest issue will be upgrades.  When you are on 9i, 
you can't restore an 8i backup.  You would have to keep 8i around for 7 years.  I 
don't purge any of my backup information out of the catalog, in case I have to restore 
an old backup.  But I haven't gone through any upgrades since I've been using rman.  
Important data that may be needed in the future is exported an copied to tape.

Jay

>>> [EMAIL PROTECTED] 09/19/02 06:08AM >>>
Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by
extenstion also as part of our DR solution.  I've been trying to locate
information on how best to configure RMAN across our organisation.  

For example it's advised you place catalog on separate server to production
server.  So server A might house catalog for server B and vice versa.  But
in a DR scenario where both servers could be destroyed there are I 'suspect'
potential implementations on overall MTTR depending on configuration.  Is it
then perhaps better to locate all catalogs on a dedicated server which
ideally would be replicated somehow to eliminate it as a singal point of
failure.

Also we have a requirment to be able to potentially recover data as far back
as 7 years.  These are currently comprised of monthly backups taken out of
regular cycle and archived off site.  I'm thinking it might be an idea to
set up a two catalogs, one for regular monthly cycle and another to record
these monthly archives as the maintenace of the catalog might be cumbersome
trying to ensure the montlhy archive data records do not get accidentally
deleted.

I've had a trawl across the Web courtesy of Google but did not find any
papers which appear to deal with these type of issues.  The RMAN User's
Guide and Reference does not appear to address them either.  Your
feedback/comments or references to papers would be much appeciated!.

RE: Lost ofall redo logs

[Mercadante, Thomas F]

I agree with you Joe.

I would *never* use an undocumented parameter unless Oracle told me to (or
unless I was testing something that I could recreate).

Using these params on the advice of someone from this list is very
dangerous.

The larger question is, why are the redo logs not being backed up?

Arun, you need to establish a backup policy *immediately* so that you are
not being put into this position again.

KG, doesn't anyone think not having a backup is a bad thing.

You can go down that route if you wish but as I remember undocumented 
parameters are best used with the assistance of OWS and not just used at 
will.

 Yes,I agree.However,I'd never tried posting to Fcity.I've

Fw: Lost ofall redo logs

[Tim Gorman]

Oh yeah!  How could I forget:  make darn 
sure that you are working with Oracle Support actively, step-by-step, if you are 
in a scenario which might call for the use of these parameters.  It would 
be *disastrous* to start down this road if unnecessary, and there are other 
quirks when using them that only OWS can diagnose and overcome...
 
...need my coffee, NOW!

From: Tim Gorman 
To: [EMAIL PROTECTED] 
Sent: Thursday, September 19, 2002 7:03 AM
Subject: Re: Lost ofall redo logs

One correction...
 
The undocumented "_corrupted_rollback_segments" 
parameter does not take a TRUE/FALSE value setting.  It is another 
list of rollback segment names (similar to "rollback_segments" and 
"_offline_rollback_segments") which will be considered corrupted.  
Roughly, the meaning of these undocumented 
parameters is (and I'm doing this from memory and pre-morning-coffee so 
those who know please correct as needed):

  rollback_segments

  
List of rollback segment names on which to 
perform ALTER ROLLBACK SEGMENT ... ONLINE immediately after opening the 
database instance.

  _offline_rollback_segments

  
List of rollback segments names to not scan 
during OPEN in order to mark transactions as "DEAD" (uncommitted) or "ROLLED 
BACK" (during instance recovery).  Also, these RBS will not be used for 
any new transactions and cannot be brought online.  Since these RBS do 
not have any DEAD transactions after OPEN, then SMON will not attempt 
rollback any txns behind the scenes.  If, while the instance is 
open, an entry in an ITL in a database block refers to one of these RBS, 
then the server process will attempt to read the transaction table in the 
RBS header and also attempt to read undo blocks in the RBS body in order to 
rollback the transaction or achieve a consistent read.  Please 
note that this is *dangerous* and that the instance can become "hung" 
through infinite loops and other nasty stuff while this is being 
performed.  In this event, the instance may have to be killed and the 
RBS involved may have to be listed in the "_corrupted_rollback_segment" 
parameter if there is any hope of using the database 
  again...

  _corrupted_rollback_segments

  
Another list of rollback segments to not scan 
during OPEN and not allow online after OPEN.  Transaction table is not 
scanned (as with "_offline_") during instance recovery and transactions 
within are not rolled back or marked DEAD, ever.  If, after the 
instance is open, an entry in an ITL in a database block refers to one of 
these RBS, then the server process will *not* attempt to reference the RBS 
in order to rollback the transaction or achieve a consistent read.  
Instead, the changes from the transaction will be marked as "committed" as 
is.
I'm sure that you can all see the danger in 
using these parameters.  Transactions that should be rolled back will not 
be.
 
With "_offline", the database will attempt 
to use info within the RBS but will never allow the RBS to be brought online for 
new transactions.  You use "_offline" if you think you can get away with 
salvaging the data in the RBS.
 
With "_corrupted", there is no hope, which 
is usually the situation if the header block of the RBS is corrupted.  In 
this case, the "after-image" data stored in the data segments (i.e. table, 
cluster, and index) are considered as "committed", since there is no way to tell 
if they really were or weren't.  The fact that the "after-images" may have 
been incomplete only adds to the fun and excitement...
 
As Arun had indicated (but not fully 
enough!), a database opened with either of these parameters really cannot be 
"trusted" for future use.  The firm recommendation is to use the database 
instance thus opened merely to salvage as much data as possible for import (one 
way or another) into a freshly-created new database.  Using these parameters will put the database on life-support 
for a short time only, hopefully long enough to extract its data.  It would 
be foolish to entrust new data to it ever again...
 
Hope this helps...

Is this because the index is locked by query only when it's used? From one
side looks reasonable, but from another - no good someone can drop an index
user by running query.

Is there any index locking at all??

Re: Lost ofall redo logs

[Ray Stell]

There is the other expensive avenue of calling in Oracle and
the DUL team.  It depends on the criticality of the data.
A few years ago a former dba here had the experience and 
it is said to have cost a mere $20K.  Maybe the data is 
worth more than that.

Hi



I need to create a user/role that among other stuff must be able to
truncate a table. I can't figure out which privileges are needed (DBA is a

Try them one by one does not sound appealing at all

RE: Query performance improvement ?

[DENNIS WILLIAMS]

David
   - I'm assuming this query is being run interactively? 
   - I recently posted a request for help on a query, and the winning
solution was to add a FIRST_ROWS hint, so naturally at this point I'm
convinced this will solve all performance issues.
   - Knowing how many rows are being returned will be helpful in planning
alternate strategies.
   - Try putting an index on your podata table.
   - How selective is your ownerid column? That is, how many distinct values
are in that column?
   - Have you considered bitmapped indexes?
   - I get by implication that you found this query in the SQL buffer and
have started there. I would suggest tracking down the application and users
to find out more about how and when they use this query. It also makes you
seem more proactive, which you are being, so you might as well get credit.
   - As to the distinct qualifier, here is a tip I found via Google:

21. Use EXISTS in Place of DISTINCT

Avoid joins that require the DISTINCT qualifier on the SELECT list when you
submit queries used to determine information at the owner end of a
one-to-many relationship (e.g. departments that have many employees).

For example:

Least Efficient :
SELECT DISTINCT DEPT_NO, DEPT_NAME 
FROMDEPT D, EMP E 
WHERE  D.DEPT_NO = E.DEPT_NO

Most Efficient :
SELECT DEPT_NO, DEPT_NAME
FROMDEPT D
WHERE EXISTS (SELECT   'X'
  FROM EMP E
  WHERE   E.DEPT_NO = D.DEPT_NO);
EXISTS is a faster alternative because the RDBMS kernel realizes that when
the sub-query has been satisfied once, the query can be terminated.

   A couple of observations and questions:
 - The distinct statement looks fairly expensive. Is there a way to
avoid it?
 - Are there any columns on POData? How many rows are in this table?
 - How many rows does this query return?
 - Do the tables contain the number of rows they will in production?
 - Have you analyzed the tables recently?

This is very rare that one would loose every online log files for the

Hey, I don't think the advice here could be bad, it is the discretion of the

Anyways, I'm more interested in KG's comment about "you will

Re: Lost ofall redo logs

[Tim Gorman]

One correction...
 
The undocumented "_corrupted_rollback_segments" 
parameter does not take a TRUE/FALSE value setting.  It is another 
list of rollback segment names (similar to "rollback_segments" and 
"_offline_rollback_segments") which will be considered corrupted.  
Roughly, the meaning of these undocumented 
parameters is (and I'm doing this from memory and pre-morning-coffee so 
those who know please correct as needed):

  rollback_segments

  
List of rollback segment names on which to 
perform ALTER ROLLBACK SEGMENT ... ONLINE immediately after opening the 
database instance.

  _offline_rollback_segments

  
List of rollback segments names to not scan 
during OPEN in order to mark transactions as "DEAD" (uncommitted) or "ROLLED 
BACK" (during instance recovery).  Also, these RBS will not be used for 
any new transactions and cannot be brought online.  Since these RBS do 
not have any DEAD transactions after OPEN, then SMON will not attempt 
rollback any txns behind the scenes.  If, while the instance is 
open, an entry in an ITL in a database block refers to one of these RBS, 
then the server process will attempt to read the transaction table in the 
RBS header and also attempt to read undo blocks in the RBS body in order to 
rollback the transaction or achieve a consistent read.  Please 
note that this is *dangerous* and that the instance can become "hung" 
through infinite loops and other nasty stuff while this is being 
performed.  In this event, the instance may have to be killed and the 
RBS involved may have to be listed in the "_corrupted_rollback_segment" 
parameter if there is any hope of using the database 
  again...

  _corrupted_rollback_segments

  
Another list of rollback segments to not scan 
during OPEN and not allow online after OPEN.  Transaction table is not 
scanned (as with "_offline_") during instance recovery and transactions 
within are not rolled back or marked DEAD, ever.  If, after the 
instance is open, an entry in an ITL in a database block refers to one of 
these RBS, then the server process will *not* attempt to reference the RBS 
in order to rollback the transaction or achieve a consistent read.  
Instead, the changes from the transaction will be marked as "committed" as 
is.
I'm sure that you can all see the danger in 
using these parameters.  Transactions that should be rolled back will not 
be.
 
With "_offline", the database will attempt 
to use info within the RBS but will never allow the RBS to be brought online for 
new transactions.  You use "_offline" if you think you can get away with 
salvaging the data in the RBS.
 
With "_corrupted", there is no hope, which 
is usually the situation if the header block of the RBS is corrupted.  In 
this case, the "after-image" data stored in the data segments (i.e. table, 
cluster, and index) are considered as "committed", since there is no way to tell 
if they really were or weren't.  The fact that the "after-images" may have 
been incomplete only adds to the fun and excitement...
 
As Arun had indicated (but not fully 
enough!), a database opened with either of these parameters really cannot be 
"trusted" for future use.  The firm recommendation is to use the database 
instance thus opened merely to salvage as much data as possible for import (one 
way or another) into a freshly-created new database.  Using these parameters will put the database on life-support 
for a short time only, hopefully long enough to extract its data.  It would 
be foolish to entrust new data to it ever again...
 
Hope this helps...

I keep my recovery catalog database on a separate disk.  I don't have a

Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by
extenstion also as part of our DR solution.  I've been trying to locate
information on how best to configure RMAN across our organisation.

For example it's advised you place catalog on separate server to production
server.  So server A might house catalog for server B and vice versa.  But
in a DR scenario where both servers could be destroyed there are I 'suspect'
potential implementations on overall MTTR depending on configuration.  Is it
then perhaps better to locate all catalogs on a dedicated server which
ideally would be replicated somehow to eliminate it as a singal point of
failure.

Also we have a requirment to be able to potentially recover data as far back
as 7 years.  These are currently comprised of monthly backups taken out of
regular cycle and archived off site.  I'm thinking it might be an idea to
set up a two catalogs, one for regular monthly cycle and another to record
these monthly archives as the maintenace of the catalog might be cumbersome
trying to ensure the montlhy archive data records do not get accidentally
deleted.

I've had a trawl across the Web courtesy of Google but did not find any
papers which appear to deal with these type of issues.  The RMAN User's
Guide and Reference does not appear to address them either.  Your
feedback/comments or references to papers would be much appeciated!.

RE: RMAN implementation strategy

[DENNIS WILLIAMS]

Sean
   Yes, remember that the real reason you keep the RMAN catalog on another
system is not for disaster recovery, but for normal recoveries. The worst
situation is where you keep the catalog in the instance you are backing up.
The second worst situation is where the recovery catalog is in a separate
instance that shares some disks with the instance it is backing up. Lose a
disk and you can't recover. Again, this isn't designed for disaster
recovery, but for normal recoveries.
   I agree with Jay, the best procedure is to take an export of your RMAN
catalog and FTP it to the server being backed up so it gets on the backup
tape.
   RMAN is not the easiest to test a disaster recovery situation. The one
factor that makes things easier is that even though you use a catalog, RMAN
also writes its information to the control file. You can perform a disaster
recovery with the control file alone. Several of us have done it. There is a
parameter that controls how long the RMAN information will stay in the
control file. I would suggest leaving that alone.
   I agree with Jay, that over a 7 year period you should consider exports
as being less vulnerable to change. After 7 years, is this data still in
your production database, or has it been deleted? For example, we have data
that old in some of our databases, but we don't apply extraordinary measures
to ensure it doesn't get deleted. For example, if a user deleted some old
data, it might not be known immediately. You might consider regular audits
to ensure the old data is intact. Anyway, I don't think this has anything to
do with RMAN. I suppose you could maintain backup records that far back, but
it would be cumbersome. One product you may want to look at is Princeton
Softech Active Archiving. If I had an absolute requirement for 7 year
retention, that is what I would use.
   RMAN is a strange product in that it works differently than you would
assume and it takes awhile to get your head around how it works. A book that
really helped me get started is Oracle Backup and Recovery 101. Robert
Freeman who participates on this list has one coming out soon.

sqlplus question

[Carle, William T (Bill), ALCAS]

Howdy,

I am spooling my sqlplus output to a file with no headings and all the fields 
separated by a delimiter. I have a field that is defined as varchar2(56), but 
typically only 4 or 5 bytes are filled. Oracle recognizes that and if you select 
length(fld1) from the table, you will get 4. But if I spool this to a file, I always 
get the full 56 bytes padded with blanks. In other words, I get 4 bytes of data and 52 
blanks for that field. I only want the four valid bytes so that my delimiter comes 
immediately after that 4th byte. My sqlplus options are as follows:

set newpage 0 space 0 linesize 5000 pagesize 0 echo off recsep off feedback off
heading off trimspool on colsep "|"

Re: Privileges needed for truncate

Jack,

  It used to be DELETE ANY TABLE.  I'm not sure if that has changed in recent 
versions.  Long ago, I setup the following procedure to allow a specific table to be 
truncated, without out the DELETE ANY TABLE privilege.  It must be owned by the owner 
of the table.  I haven't dealt with this issue in years, so if things have changed 
since Oracle 7, somebody else can chime in.

   Yes, remember that the real reason you keep the RMAN catalog on another
system is not for disaster recovery, but for normal recoveries. The worst
situation is where you keep the catalog in the instance you are backing up.
The second worst situation is where the recovery catalog is in a separate
instance that shares some disks with the instance it is backing up. Lose a
disk and you can't recover. Again, this isn't designed for disaster
recovery, but for normal recoveries.
   I agree with Jay, the best procedure is to take an export of your RMAN
catalog and FTP it to the server being backed up so it gets on the backup
tape.
   RMAN is not the easiest to test a disaster recovery situation. The one
factor that makes things easier is that even though you use a catalog, RMAN
also writes its information to the control file. You can perform a disaster
recovery with the control file alone. Several of us have done it. There is a
parameter that controls how long the RMAN information will stay in the
control file. I would suggest leaving that alone.
   I agree with Jay, that over a 7 year period you should consider exports
as being less vulnerable to change. After 7 years, is this data still in
your production database, or has it been deleted? For example, we have data
that old in some of our databases, but we don't apply extraordinary measures
to ensure it doesn't get deleted. For example, if a user deleted some old
data, it might not be known immediately. You might consider regular audits
to ensure the old data is intact. Anyway, I don't think this has anything to
do with RMAN. I suppose you could maintain backup records that far back, but
it would be cumbersome. One product you may want to look at is Princeton
Softech Active Archiving. If I had an absolute requirement for 7 year
retention, that is what I would use.
   RMAN is a strange product in that it works differently than you would
assume and it takes awhile to get your head around how it works. A book that
really helped me get started is Oracle Backup and Recovery 101. Robert
Freeman who participates on this list has one coming out soon.

Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by
extenstion also as part of our DR solution.  I've been trying to locate
information on how best to configure RMAN across our organisation.

For example it's advised you place catalog on separate server to production
server.  So server A might house catalog for server B and vice versa.  But
in a DR scenario where both servers could be destroyed there are I 'suspect'
potential implementations on overall MTTR depending on configuration.  Is it
then perhaps better to locate all catalogs on a dedicated server which
ideally would be replicated somehow to eliminate it as a singal point of
failure.

Also we have a requirment to be able to potentially recover data as far back
as 7 years.  These are currently comprised of monthly backups taken out of
regular cycle and archived off site.  I'm thinking it might be an idea to
set up a two catalogs, one for regular monthly cycle and another to record
these monthly archives as the maintenace of the catalog might be cumbersome
trying to ensure the montlhy archive data records do not get accidentally
deleted.

I've had a trawl across the Web courtesy of Google but did not find any
papers which appear to deal with these type of issues.  The RMAN User's
Guide and Reference does not appear to address them either.  Your
feedback/comments or references to papers would be much appeciated!.

Howdy,

I am spooling my sqlplus output to a file with no headings and all the
fields separated by a delimiter. I have a field that is defined as
varchar2(56), but typically only 4 or 5 bytes are filled. Oracle recognizes
that and if you select length(fld1) from the table, you will get 4. But if I
spool this to a file, I always get the full 56 bytes padded with blanks. In
other words, I get 4 bytes of data and 52 blanks for that field. I only want
the four valid bytes so that my delimiter comes immediately after that 4th
byte. My sqlplus options are as follows:

Yechiel - Excellent point. Even better, burn the exports on a CD, making

After 7 years your tapes can be unreadable.
If you use exports you can periodically restore them and

I think the trimspool is just trailing blanks so unless you made that the

I see using the statement on one line sets all on or off

Show trims

Sounds like your column is getting padded with empty bytes ???
Dispite lentght reporting the actual data

You might have to trim it yourself

Sounds to me like the trimspool should do it...

Are you sure its set on

ME@DB1 -> trimspool on
SP2-0734: unknown command beginning "trimspool ..." - rest of line
ignored.

Try  set trims on 

Or 

Set trimspool on

   - I'm assuming this query is being run interactively?
   - I recently posted a request for help on a query, and the winning
solution was to add a FIRST_ROWS hint, so naturally at this point I'm
convinced this will solve all performance issues.
   - Knowing how many rows are being returned will be helpful in planning
alternate strategies.
   - Try putting an index on your podata table.
   - How selective is your ownerid column? That is, how many distinct values
are in that column?
   - Have you considered bitmapped indexes?
   - I get by implication that you found this query in the SQL buffer and
have started there. I would suggest tracking down the application and users
to find out more about how and when they use this query. It also makes you
seem more proactive, which you are being, so you might as well get credit.
   - As to the distinct qualifier, here is a tip I found via Google:

21. Use EXISTS in Place of DISTINCT

Avoid joins that require the DISTINCT qualifier on the SELECT list when you
submit queries used to determine information at the owner end of a
one-to-many relationship (e.g. departments that have many employees).

For example:

Least Efficient :
SELECT DISTINCT DEPT_NO, DEPT_NAME
FROMDEPT D, EMP E
WHERE  D.DEPT_NO = E.DEPT_NO

Most Efficient :
SELECT DEPT_NO, DEPT_NAME
FROMDEPT D
WHERE EXISTS (SELECT   'X'
  FROM EMP E
  WHERE   E.DEPT_NO = D.DEPT_NO);
EXISTS is a faster alternative because the RDBMS kernel realizes that when
the sub-query has been satisfied once, the query can be terminated.

   A couple of observations and questions:
 - The distinct statement looks fairly expensive. Is there a way to
avoid it?
 - Are there any columns on POData? How many rows are in this table?
 - How many rows does this query return?
 - Do the tables contain the number of rows they will in production?
 - Have you analyzed the tables recently?

oraperf report - 2 queries

[John . Hallas]

I have just tried using www.oraperf.com again after about a year since the
last time.
The output both in terms of formatting, readability and comment are much
improved on what was already a valuable resource
Well done Anjo

2 questions that the list (or even Anjo) may be able to answer for me

With regard to processes the report states
"Another option is to decrease the init.ora parameter "processes". The LGWR
needs to scan all processes to find each process that is waiting for the
commit to be written. The current value for processes is 1300. Try setting
it close to the number of process that you really need."
What I do not understand is that processes is a maximum number so LGWR may
have to read all processes that exist but that number is well below the 1300
level but I cannot see an overhead in having the processes set to high in
that respect. I do agree that other values are calculated based upon the
value of the processes setting and so that is a good reason to reduce the
value to a more realistic one of about 500.
As a side note Steve Adaams states that there is no negative impact of
having too high a processes value (In 8 not necessarily 8i)
(http://www.ixora.com.au/q+a/params.htm

The second point is with regard to  recommending the use of a smaller log
buffer and a smaller log_io_size (recommended to be 3 times avg redo size
per commit).
I was wondering if anyone knows where the current value is recorded. It is
not available from V$parameter and I assume it is in one of the X$ views.
My log buffer is 4M and the redo log block size is 512 but I am stumped as
to the value of _log_io_size ( I think it should be 8192 ie 4M/512)

Thanks

Re: RMAN implementation strategy

After 7 years your tapes can be unreadable.
If you use exports you can periodically restore them and
backup them to a new tape.

   Yes, remember that the real reason you keep the RMAN catalog on another
system is not for disaster recovery, but for normal recoveries. The worst
situation is where you keep the catalog in the instance you are backing up.
The second worst situation is where the recovery catalog is in a separate
instance that shares some disks with the instance it is backing up. Lose a
disk and you can't recover. Again, this isn't designed for disaster
recovery, but for normal recoveries.
   I agree with Jay, the best procedure is to take an export of your RMAN
catalog and FTP it to the server being backed up so it gets on the backup
tape.
   RMAN is not the easiest to test a disaster recovery situation. The one
factor that makes things easier is that even though you use a catalog, RMAN
also writes its information to the control file. You can perform a disaster
recovery with the control file alone. Several of us have done it. There is a
parameter that controls how long the RMAN information will stay in the
control file. I would suggest leaving that alone.
   I agree with Jay, that over a 7 year period you should consider exports
as being less vulnerable to change. After 7 years, is this data still in
your production database, or has it been deleted? For example, we have data
that old in some of our databases, but we don't apply extraordinary measures
to ensure it doesn't get deleted. For example, if a user deleted some old
data, it might not be known immediately. You might consider regular audits
to ensure the old data is intact. Anyway, I don't think this has anything to
do with RMAN. I suppose you could maintain backup records that far back, but
it would be cumbersome. One product you may want to look at is Princeton
Softech Active Archiving. If I had an absolute requirement for 7 year
retention, that is what I would use.
   RMAN is a strange product in that it works differently than you would
assume and it takes awhile to get your head around how it works. A book that
really helped me get started is Oracle Backup and Recovery 101. Robert
Freeman who participates on this list has one coming out soon.

Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by
extenstion also as part of our DR solution.  I've been trying to locate
information on how best to configure RMAN across our organisation.

For example it's advised you place catalog on separate server to production
server.  So server A might house catalog for server B and vice versa.  But
in a DR scenario where both servers could be destroyed there are I 'suspect'
potential implementations on overall MTTR depending on configuration.  Is it
then perhaps better to locate all catalogs on a dedicated server which
ideally would be replicated somehow to eliminate it as a singal point of
failure.

Also we have a requirment to be able to potentially recover data as far back
as 7 years.  These are currently comprised of monthly backups taken out of
regular cycle and archived off site.  I'm thinking it might be an idea to
set up a two catalogs, one for regular monthly cycle and another to record
these monthly archives as the maintenace of the catalog might be cumbersome
trying to ensure the montlhy archive data records do not get accidentally
deleted.

I've had a trawl across the Web courtesy of Google but did not find any
papers which appear to deal with these type of issues.  The RMAN User's
Guide and Reference does not appear to address them either.  Your
feedback/comments or references to papers would be much appeciated!.

RE: Why does my insert creates so many logs?

[Viral Desai]

A couple of things to try ---

1. Drop the indexes and primary key instead of disabling them. Insert the 
data and recreate pk.

2. This could be due to changes in data dictionary, when you insert large 
number of rows in the table, new extents may be allocated or high water mark 
of the table would be modified. This information need to be logged. I think 
that the redo generated due to this should not be very large though.

Hope this helps.

Howdy,

I am spooling my sqlplus output to a file with no headings and all the
fields separated by a delimiter. I have a field that is defined as
varchar2(56), but typically only 4 or 5 bytes are filled. Oracle recognizes
that and if you select length(fld1) from the table, you will get 4. But if I
spool this to a file, I always get the full 56 bytes padded with blanks. In
other words, I get 4 bytes of data and 52 blanks for that field. I only want
the four valid bytes so that my delimiter comes immediately after that 4th
byte. My sqlplus options are as follows:

set newpage 0 space 0 linesize 5000 pagesize 0 echo off recsep off feedback
off
heading off trimspool on colsep "|"

RE: sqlplus question

[Naveen Nahata]

"set Trimspool on" will only trim the empty spaces at the end of each line.

The only way i know to trim in between the lines is to concatenate all the
columns

SELECT column_1 || '|' || column_2. FROM .

Sounds to me like the trimspool should do it...

Are you sure its set on

ME@DB1 -> trimspool on
SP2-0734: unknown command beginning "trimspool ..." - rest of line
ignored.

Try  set trims on 

Or 

Set trimspool on

OT: oracle and appliance storage

[Rick_Cale]

Hi All,

Server A,  Win 2000, Oracle 8.1.7
Server B, Win 2000 with Auspex storage appliance

We want to test all datafiles to be on Server B.  How does Oracle on server
A know about datafiles on server B. It is my understanding
that Oracle does not recognize map drives. There must be another way that
Oracle recognizes drives on Server B.  Can anyone shed
any light?

Thanks
Rick

Maybe you could use it for statspack.

RE: Staspack Grapher/Viewer ?

[mkb]

And if you don't want to use MS Graph, you can use
Perl's built-in graphing facility (see Programming
Perl) or gnuplot.

I had developed something similar at a previous gig
but I used gnuplot.

Process question

[Jay Hostetter]

Do I have something wrong with this query?  I thought that each oracle process 
corresponded to one database connection (unless you are using MTS, which we aren't).  
This query surprised me.  It shows that two different oracle database processes each 
correspond to 3 database connections.  What am I missing?

Thanks,

Re: Lost ofall redo logs

Hi People

I don't think that i need to update my CV, since I don't administer the
database in subject and that am trying to solve the an unhappy customer's
problem.

I had already researched and tried almost everything that you suggested me
and what really solved went use to suggestion of the not documented
parameter (_allow_resetlogs_corruption), then do a full export, then
recreate the database and do a full import.

I think that this list is wonderful, whenever I had a problem and I didn't
get to solve I asked help here and I went very well assisted, much better
than the oracle support.

Thank you!

RE: Staspack Grapher/Viewer ?

[Post, Ethan]

I have a 1.5 MB zip file containing my old web site for called gnumetrics
which uses a PL/SQL package and MRTG to chart performance data.  If someone
has a webserver I can load this to I will.  It is old but it works.  At the
very least you will get some ideas on how to do this.  I store all my data
internally now using the same aggregation policy as MRTG to get up to one
year of data in very small size.  I chart it using ODBC an Access with
Microsoft Graph.  Works very well and I get very useful reports.

PL/SQL help

[Ron Thomas]

I am building a dynamic sql statement which will contain varying number of bind 
variables depending
on user selection criteria.  As an example, the sql statement may be:

c_sql := 'select col1 from  atable where col2 = :1' ;

or it may be

c_sql := 'select col1 from  atable where col2 = :1 and col2 between :2 and :3' ;

or it may be ... etc.  I am trying to avoid ugly code such as:

IF case1 THEN
  OPEN csr FOR c_sql USING var1 ;
ELSIF case2 THEN
  OPEN csr FOR c_sql USING var1, var2, var3 ;
ELSIF .
END IF ;

Once the sql statement is created, it will be opened/closed multiple times, so I want 
to use bind
variables to avoid parsing.

So I thought, hum, sounds like a job for EXECUTE IMMEDIATE, but in the various 
incarnations I tried,
could not get it to work.  The FM have not been much help (still looking tho).

What am I missing?

Best method to move Filesystems to RAW Devices.

[Nat]

We are planning to move to raw devices for all our existing file systems.
Our database size is around 400 Gig. What is the recommended method that you
guys feel is best as far as time
required to convert and ease of conversion.

We feel we cannot use export - import as this may take more time for
conversion..
I checked many documents to find out  the best method, there are few
suggestions to use RMAN to convert to raw.
seems it is fastest. At this point we have not configured RMAN on our
databases so this suggestion seems to be of no use for us.

Please let me know, if any of you went through this exercise and any
suggestions and tips will be more beneficial,

Thanks in advance,

RE: Why does my insert creates so many logs?

[Johnston, Tim]

What version?  What is the definition of table A?  Have you enabled parallel

be automatic with the parallel hint but...

Hi.

A developer of mine is running a large insert as
select:

insert /* parallel hint */ into table A 
nologging 
(select * from table b where ...);

There are no indices on table A and a PK disabled.
Still that insert generates a large amount of logs.
What could be the reason for that? Any ideas? Table A
is not partitioned and has NOLOGGING attribute on the
dba_tables set to Yes.

thanks

copying all schemas except sys

[Ben]

Hi

Starting with Oracle8i there is a problem with using full export
and full import to re-create a database. The import coughs up a
lot of errors due to the SYS schema (replication and help objects).
How do people go about moving all the schemas from one instance to
another without manually creating all the schema owners in the
new instance and then exporting/importing every schema by name.
What I want is an "ignore sys schema" parameter in the export
utility.

Thanks,

Ben

count(*)

[Rishi . Jain]

Hi Gurus,

In one of our insert intensive application we are inserting around 3-4
million rows / hour. Also this app needs to do a count(*) of the tables
every 10 minutes for verifying some application based logic. This is really
killing us and it takes a lot of time. 

Can you please guide me to a direction ( built in functions or something
similar). 

Actually this app is being ported from Informix. Informix can somehow keep a
trak of the count(*) of a  table in its header somewhere.

And yes I have tries count(1) , count(indexed_column) etc.


Thanks In Advance.

RE: High values

[DENNIS WILLIAMS]

John - Since nobody has replied to your question, I discussed it with a
fellow COBOL programmer. I think that in COBOL you normally would use this
in an iterative loop, as a comparison. In SQL itself, you rarely iterate, so
you probably don't have that much need for a HIGH-VALUE. In PL/SQL you might
be more likely to need it. Myself, I have used such a thing in the C
language before, and there was usually a precompiler value that you could
include. For Oracle, the maximum integer that can be represented is 38 9's
times 10 to the 125th. power. Here is a web address that lists a lot of the
Oracle limits as of 8.0.5.

RE: Staspack Grapher/Viewer ?

[Jesse, Rich]

This has me thinking.  What exactly do you want to graph?  I guess I'm just
trying to see some value in graphing data from a single SP report.  Graph
waits as a pie chart?  Or would it be for several reports combined?

Also, after looking again at the layout of an SP report, a home-rolled query
would do much better at feeding MRTG or GNUPLOT.

Just wondering if I can get myself into yet another project...  :)

RE: Rule Vs Cost

[Surendra . Tirumala]

John,

Thanks again for providing those links to Tim's paper and yours. 
They are really helping in understanding/talking about CBO in a better way.
BTW, Today I have experienced the Over-kill of PQ you mentioned. One of our
reports which used to run very fast kept hanging in there and I had to
disable the PQ at table level and use hints whenever needed.

Surendra

Surendra,
 
Saw no replies, so just pitching in. Moving over to the CBO does give you
flexibility and the option for a query to 'self-tune' itself depending on
the object statistics. (Dare I say 'self-tune' with all the notes flying
around :)  Anyway - what I meant was that _most_ queries would adjust their
execution path depending on these stats. The two inputs to this process is
the objects stats themselves as well as the algorithm that operates on these
stats. This 'algorithm' can further be influenced (for want of a better
term) using a number of init.ora parameters (documented and undocumented).
The art is to determine the right values, but there are a few values such as
OPTIMIZER_INDEX_CACHING and OPTIMIZER_INDEX_COST_ADJ and that you will not
go wrong with - Tim Gorman deals with these two in his excellent paper on
the CBO. Browse at Tim's site at 'http://www.evdbt.com' .
 
At the same time, moving to the CBO without understanding this complex beast
is like getting into a souped-up Porshe when you have just got your Trainee
driver permit.
There are a number of issues with this that even seasoned DBAs miss... I
tried to cover these issues in my paper - just follow the second link on
'http://www.geocites.com/john_sharmila/links.htm'.
 
One way of performing a gradual move to the CBO is by gathering stats and
then using an ON-LOGON trigger to switch the optimizer_goal to CHOOSE for
selected programs/sessions. A final hint: Use PQ with caution - overuse and
ill-planned implementation can be potentially deadly and overwhelme your
CPUs. IMHO PQ is to be used ony in certain cases and that too only from the
SQL using Hints, which will limit PQ only to that SQL.

Hello All,
 
I am observing that some of our production instances(8i) are running on Rule
Based Optimizer. I am dealing with the task of tuning a bunch of reports.
While I continue my adventures, can you guys please let me know if there is
any reason to continue with age old Rule based optimizer when we have so
many advantages with CBO? I am exploring the option of using PQ with couple
of reports but the RBO is forcing me to stop thinking about it. 
 
All your suggestion are very much appreciated.

RE: Why does my insert creates so many logs?

[Fink, Dan]

This might sound like an exercise in pointlessness but here goes...

Are you sure you are generating the redo?

Use the following to get the sid of the sessions generating redo and then
track back to the session/process/statement info. I realize that the query
does not exactly query redo, but I have always found that the correlation
between block_changes + consistent_changes and redo entries matches up. If
there are others who can point out the fallacy of my thinking, I await
enlightenment. (No jokes about changing _spin_count please...)

select sid, (block_changes + consistent_changes)
from v$sess_io
where (block_changes + consistent_changes) > 5000   /* insert a reasonable
value here */
order by 2 desc;


   SID (BLOCK_CHANGES+CONSISTENT_CHANGES)

All the indices are dropped and the PK is disabled.
I agree that there are some changes to be done
in the data disctinary tables, but the amount of
archived logs - about 90M per minute looked too high
to me

RE: count(*)

[Suri, Deepak]

I have in the past used parallel hints to speed up a count(*) kind of full
table scan query.

Hi Gurus,

In one of our insert intensive application we are inserting around 3-4
million rows / hour. Also this app needs to do a count(*) of the tables
every 10 minutes for verifying some application based logic. This is really
killing us and it takes a lot of time. 

Can you please guide me to a direction ( built in functions or something
similar). 

Actually this app is being ported from Informix. Informix can somehow keep a
trak of the count(*) of a  table in its header somewhere.

And yes I have tries count(1) , count(indexed_column) etc.


Thanks In Advance.
