Recovery Plan for Upgrade !!

2003-08-15 Thread Reddy, Madhusudana
Hello All,
We are upgrading the database from version 8.1.7.3 to 8.1.7.4. What if the Upgrade 
fails ( I did it couple of times , but never failed for me), How to recover to 
previous version??

Here is what I think , please correct me and add some more points here.

1. Backup the $ORACLE_HOME for version 8.1.7.3
2. Take backup of SYSTEM tablespace ( after the clean shutdown of the DB and just 
before Upgrade )
3. Make all other tablespaces READ ONLY ( except system / TEMP ( we use tempfiles )/ 
RBS ) When we running catalog.sql and catproc.sql 

In case of any failure while patching , can we start the DB after restoring  
$ORACLE_HOME and System tablespace from backups ?? 

Can some one share your experiences , also it would be beneficial for me , if someone 
send me a upgrade checklist / process offline 

THANKS  !!

Madhu Reddy

RE: Redo Copy Latch contention ??

2003-07-02 Thread Reddy, Madhusudana
Thanks Kirti,
We have HP Openview implemented on our database and hence got some alert on redo copy 
latch. When I have queried the database I found the contention on this latch. Yes we 
have other performance issues ( HIGH CPU utilization , because of lotta bad code ).
and We are checking every possible contention on the database. 

Question : How can I determine if this redo copy latch is causing the performance 
issues , guess that is my main question before altering some hidden parameter in 
init.ora.

According that suggestion you do seem to have redo copy latch contention. 
As far as getting that ratio close to suggested value, you may set some special 
init.ora
parameters. There is plenty of notes on Metalink for that.
But, you should first determine if this is causing any performance issue. Have you 
explored all
other avenues to address those issues. If not, I would not worry about this 
contention.

1. query on v$session to get the SID

2. Then pass sid to the follwing query

select sql_text 
from v$sqlarea a, v$session b 
where a.hash_value=b.sql_hash_value

RE: nfile parameter problem

Now do a select from table in my tablespace (it's not buffered because I
took tablespace offline/online)



SQL select * from t;



 A

--

 1



Let's see who has opened the file



SQL !/usr/sbin/fuser /u01/oradata/TEST817/test2_01.dbf

/u01/oradata/TEST817/test2_01.dbf:29070o 390o



Now I'll log off to see whether the file remains opened



SQL exit

bash-2.03$ /usr/sbin/fuser /u01/oradata/TEST817/test2_01.dbf

/u01/oradata/TEST817/test2_01.dbf:  390o



Of course it doesn't, because when exiting, my server process also dies
(along with it's file handlers). But DBWR still has it open



bash-2.03$ sqlplus system/[EMAIL PROTECTED]

Another try



SQL select server from v$session where sid = (select sid from v$mystat
where rownum = 1);

SQL select p.spid

from v$process p, v$session s

where s.sid = (select sid from v$mystat where rownum = 1)

and p.addr = s.paddr;

  234

SPID

-

I logged on, let's see if my session automatically opens the file



SQL !/usr/sbin/fuser /u01/oradata/TEST817/test2_01.dbf

/u01/oradata/TEST817/test2_01.dbf:  390o



No, since I haven't done any (unbuffered) reads from this file.

But let's try to read:



SQL select * from t;



 A

--

 1



SQL !/usr/sbin/fuser /u01/oradata/TEST817/test2_01.dbf

/u01/oradata/TEST817/test2_01.dbf:  390o



Still nothing, because the blocks are in buffer cache, thus nothing to be
read from file itself



SQL exit

By the way, additional processes such are CKPT and SMON will open the file
on their time.



Happy experimenting! :)

nfile parameter problem

2003-06-25 Thread Reddy, Madhusudana
Hello All,
We have Oracle ( 8.1.7 ) running on HP-UX and experiencing HP-UX Error: 23: File table 
overflow errors , so initially we have bumped the nfile kernel parameter to 128 K. 
Just couple of days back we have seen the same problem and database crashed. Glance 
Plus shows us that Oracle processes are opening lot of files. some Oracle processes 
are opening over 400 files. I have a sample shown below and open files at this moment 
is 87396 out of 128010. During the peak hours open files are reaching 100K plus.

My main question to you all is : Is there any way to reduce the # of open files opened 
by Oracle processes ??

We have some java processes ( which are really worst ) opens lot of dedicated 
connections using thin drivers , can it be handled in a better way like using the 
THICK driver or MTS ??

I definitely need your inputs

   On the Java side, are they using an application server (like Oracle9i AS
or Weblogic or Tomcat?). If not, suggest that they should. If they are,
there are connection pool settings that control how many connections will be
opened. I have had test databases nailed by that one.

Issues with changing the SYS and SYSTEM password !!

2003-06-12 Thread Reddy, Madhusudana
Hello ALL,
We have a plan to change the SYS and SYSTEM user's passwords. There are two DBLINKs 
created for each user and I am not sure who is using them , Is there any way ( trace ) 
to check who is using these DBLINKs ??

Also you might have done the password changes many times for SYS/SYSTEM , were there 
any issues associated with password change ??

The following info. might be useful for your replies:

SQL select * from v$pwfile_users;

USERNAME   SYSDB SYSOP
-- - -
INTERNAL   TRUE  TRUE
SYSTRUE  TRUE

remote_login_passwordfile=exclusive


I will be grateful , pl share your experiences with me.

Thank You,
Madhu Reddy

RE: Deleting Statspack tables.

2003-06-11 Thread Reddy, Madhusudana
Tim's script is not much of different except deleting from the stats$sqltext from 
original SPPURGE.sql . But if you see my mail below I do have a lot of other tables 
which needs to be purged periodically.

Thank You,

Um, if I understand correctly, you're just trying to
keep the volume down in your statspack tables.

I use Tim Gorman's sppurpkg.sql package (on several
different versions across several different operating
systems).  (www.evdbt.com)

I have it set up to keep 14 days of data, but you can
change that.  It schedules the dbms_job for you.  I
just set up his job when I configure statspack on a
new database, and then I never need to think about it
again.

You might take a look and see if it'll work for you.

Version : 8.1.7.3.

I am not sure how it is working for you just by deleting from stats$snapshot and we do 
not have 8.1.6 here.


Thanks

Reddy - You didn't mention your Oracle version. I am on 8.1.6 and I don't
think those scripts are available there (sorry, busy day, no time to
research). So I just delete from stats$snapshot. It seems to remove data
from the associated tables just fine. First I select the snap_id and
snap_time from stats$snapshot to determine which snapshots to remove. It
runs slowly (because of all the child tables?), so I just remove a hundred
or so at a time.

  All,
  
  what Actually Oracle 
  will do when we kill the JOB by " kill -9" , instead of "Alter System 
  ". What about the Rollback 
??
  Any PARALLEL parameters in init.ora has any effect if 
  we kill the process by "kill -9".

  Any other inputs on

Some to the graph does not appear properly for some reason.

In any case, this may be a bug.  Please read MetaLink Document  166924.1

In part it says:


 
1. Self Deadlocks 
 
It occur when one session tries to get a lock on a resource that he 
already has in some way. 
Normally, the Oracle engine should detect those situations and should 
avoid 
the signalling of the ORA-04020 to the end-users. When a self deadlock 
detection occurs, 
Oracle generates a trace file in the user_dump_dest. It is only considered 
as a bug if 
an ORA-04020 is signalled to the end-user. 
 
2. Deadlocks between concurrent sessions 
 
The ORA-04020 deadlock error usually occurs when two user processes 
cannot complete their transactions because they are trying to access 
the same resource.

Here is the Graph i can see in the trace file : ( SELF DEADLOCK  )











A deadlock among DDL and parse locks is detected.
This deadlock is usually due to user errors in
the design of an application or from issuing a set
of concurrent statements which can cause a deadlock.
This should not be reported to Oracle Support.

the errors which cause the deadlock:

If you are getting ORA-60 deadlock errors, how about posting the

Another interesting thing is , after restarting the job ( after killing

Updating a huge hash partitioned table.

Hello All,
I have a requirement to update a table which is hash partitioned and having
a local prefixed index with keys (STORE,
 SKU, ACTION_DATE, TRAN_TYPE) .   I have to update only one column called
'WH' to a new value where  store=store#, wh= 0 and tran_type = -1. Explain
plan shows me FULL TABLE access. 
Sample query would be like this

Update  table_name 
set wh=-1
where store=store_no
and wh=old_value
and tran_type=value

Any suggestions to have better performance ??

RE: Calculating new PCTFREE and PCTUSED !!!!!1

2003-01-18 Thread Reddy, Madhusudana
Charlie,

Would you please post your PL/SQL code here.I might wanted to use/tweak
it .

Also your formula for PCTFREE is pctfree = pctfree + 5 , if table exceeds 5%
of chained rows and some DBAs advocate to  average row length.

Jared, whats u r idea on this , what would you do to alter PCTFREE or
PCTUSED ..

Anybody ??

What I've done, is I have some PL/SQL code which looks for chained rows.
When the number of chained rows exceeds 5% it proceeds to unchain the rows.
Upon completion it increases the PCTFREE by 5%  decrease PCTUSED by 5%.
This process continues until they reach values which don't induce chaining.
This process runs once a month after our month-end processing completes.

Reddy - No I have not used that script. But most of Don's stuff is quite
good. I thought it might illuminate some issues for you. Sorry if it didn't
help.
   The PCTFREE and PCTUSED parameters mainly need tweaked when your data is
volatile, when existing rows are updated with additional data. Is your data
very volatile?

RE: Capacity Planning -- Expecting the DB growth !!!

2002-12-17 Thread Reddy, Madhusudana
Hello All,

It should include all as you said , but since I do not belong to a capacity
planning group in my shop , I mostly concentrate on the DB growth . I have
taken Sales as business object to correlate with the DB size . I think in
our case both of them are directly proportional. ( Business objects may vary
from shop to shop )

first step I have done is calculating the : Growth factor = avg. History Db
growth / avg Hist Sales growth

Second Step : identifying the Sales projection for the next fiscal year (
Ie. I have to get sales growth percentage from the business team , for
example 15% and multiply with sales history, for each week I guess.)

3rd step: Now I have sales projection and growth Factor , and can the
projected DB growth .


Well The above is the thing I am working on by having some queries to get
the data from the DB. Also I have to automate the whole process .

I would like to know how this Capacity planning followed in your shop.
What's your answer when your group manager asks how much disk we need for
holiday prep ?? Like this we can have many questions. I know somebody is
having a better approach getting followed . Would appreciate if you share
with us.

or somebody can better help me in identifying  the Q? from managers


Thank YOU all for your replies

Check the link Kirti has posted (orapub).

Is capacity planning only on the database size ?
In my mind it also includes :
   Transaction description (online and batch)
   Transaction frequency (online and batch)
   Transaction window 
   Networking requirements
   Number of users (all and concurrent)
   Overall disk space (inside and outside the
database)

To be perfectly honest, I had an unfair advantge as I worked in Siebel 
Expert Services for 2.5 years, flying all over the world, with a broom in 
one hand and a mop in the other, cleaning mess after mess at customer 
sites,where usually the integrator stuffed things up mainly due to 
ignorance on almost all fronts. I then spent a good portion of this year in 
Siebel Engineering where I was their lead performance engineer for the 
Siebel Analytics and Marketing products on Oracle.Then in August, I finally 
had enough and quit.

I don't know that there is a top 10 list. But always the 3 golden rules for 
being a good DBA:
1. know your data.
2. know your data.
3. know your data.
Everything is supplementary after that.

Dennis  Ferenc,
Your discussion is a good read ...

You guys are able to understand how your applications are working WITH
Oracle, like using RULE/COST optimizer , Table Scans and also how it is
using the Oracle capabilities. I also wanted to know more about the
application running on top of Oracle . Would you guys GUIDE me with some
steps ( may be top 10 and how to do that ) , or you have any document which
you have prepared in the past will be great help for guys like me who 
wanted
to know more :))-

This LIST is always been a great HELP for me... Happy Thanks giving to YOU
ALL.

   Thanks so much for providing an insight into what you do. Lawson uses
Oracle in quite a simpler method. No joins, just individual table
access. No
table scans, each access is hinted to use a specific index. Crude but
effective. The first issue is that it doesn't use all of Oracle's
capabilities. The second issue is that it provides little opportunity
for
Oracle tuning experts such as yourself. But customers keep pressing for
better use of Oracle, so there is hope yet. ;-)
   Based on what I've seen out of Lawson and wait statistics, I'm
applying
my efforts to reducing physical I/O. I just configured several tables
for
the KEEP and RECYCLE pools.

Dennis

as you know, there is no 'follow these steps to get a better performing
application' guide when it comes to tuning. An intimate knowledge of
what
the application does is a must. I sell myself (tried the street corners
but
was not getting much intrest) as a Siebel performance tuning specialist,
so
when customers say 'Oh, you are an Oracle DBA !', I respond with 'No,
Oracle DBA is just one of the things I do in order to get my job done'.
there are plenty of DBA's out there, (and DBB's too), but understnading
how
the application (in my case Siebel) works and what it is trying to
accomplish from a functional perspective helps me to know immediately
what
is the framework of limitations I can work in. For instance, Siebel is
written for RBO, so when someone comes spouting partitions and bitmap
indexes, I buzz them out on try 1.

now for Siebel specific EIM (Enterprise Integration Manager) type tuning
,
when I see that index range scans are killing me, I try to reduce the
batch
size first so that it will not have to go through as many records per
value
(think of a batch size of 20,000 records where it is doing a correlated
subquery on just the batch_id). Now change this into 100 batches of 200
rows each, and immediately you have a huge saving in logical IO, since
each
time excpet the first iteration, the index blocks and table blocks
should
be found in DBBC (Also see Cary's paper on www.hotsos.com which goes
into
deeper details on the latches needed and the recursive calls for buffer
hits.) Other things include looking at SQL where you can see it is using
an
index to look up a row in the table to get a single value (column). In
this
case, for a large load, it may be beneficial to recreate this same index

with the column concatenated on the end, and avoid the table lookup
altogether. Also knowing EXACTLY how RBO works (there are only about 20
rules and in reality only 5 or 6 get used in an application), will help
you
to know when it may even be beneficial to DROP an index (gasp ! can he
be
serious ? Youbetcha ! ). anyway, that is it for today, class dismissed.

Have a great day !

10G? Must have a lot of objects not belonging to sys/system in there.
(Unless someone turned auditing on and forgot about it.) I'd say the system
tablespace must be so fragmented that it's best to create another database
and recreate the users and import their data with default and quota set to
locally managed tablespace(s).

Check for 3rd party applications going in there.  Peoplesoft was one that
used to use System as it's default tablespace.

Also in beginning in 11i apps 11.5.5 the patches now go in the database so
System grows quite a bit.

Try these two queries to find out allocated space in SYSTEM tablespace:

from dba_segments

group by owner, tablespace_name;

Madhu,
  From all that I understand about the system tablespace, There is no
easy way to defragment the system tablespace. An Export, rebuild, Import
( under the direction of Oracle Support according to the metalink notes)
is a way to defragment the system tablespace.
 #What was the initial size of the system tablespace when created? Can
you explain the increase in size? Is your performance suffering and the
users complaining?
Be sure that you do a backup of everything before you attempt to work
on defraging the system tablespace.
Good luck,
Ron

If you mean to say Writing is Creating the segments , I did not see
any
other user except SYS and SYSTEM users in the SYSTEM tablespace. But
some
user IDs which were created for replication purpose have the
Default_tablespace as SYSTEM , but they do not have any segments in
SYSTEM
tablespace . And there wont be any chance of creating a new
object/segment
under those users.

I believe the SYSTEM tablespace was fragmented and now I would like to
resize it , would like to know best and fastest way

check to see if anyone has the system tablespace as their default

RE: SYSTEM TABLESPACE IS SO HUGE ?

Paul ,
Yours is an excellent idea, but I have never implemented it in SYSTEM
tablespace.
I could see some Indexes  Tables owned by SYSTEM and OUTLN users in the
SYSTEM tablespace .. can I rebuild these indexes ?? 
Or can I move all objects ( tables  indexes to SYSTEM  OUTLN default
tablespaces )..

I too do not want to touch any SYS objects ... Would like to know the
possibilities with no downtime !!!

You've already been given the best and simplest method to defragment the
SYSTEM tablespace:  export, recreate with locally
 managed tablespaces, do a full import. You _could_ take a look at which SYS
objects have many extents and edit sql.bsq
**caution**caution**caution** before recreating your new database.

Before you do that, figure out if the tablespace is really fragmented or
just heavily used.  Each version of Oracle has required
more SYSTEM tablespace.  Oracle Apps could be filling it up.  Or you could
just have lots and lots of source code.
Take a look at dba_extents and dba_free_space to see if you have lots of
unusable space.  It's pretty conceivable, since
Oracle likes to put a 50% increase on many of its segment definitions.

If the tablespace has lots of unusable free space,  you could possibly try
reclaiming the space the way I've often had to
reclaim space in a live database with no downtime allowed.  If Oracle will
allow alter index rebuild and alter table move
on the objects (I've never tried to move anything belonging to SYS), you
could construct a tablespace map showing where
each extent begins and ends.  Hopefully you'll have an overextended index or
table sitting at the bottom of a datafile.
With nobody else able to access the database, do an alter index rebuild or
alter table move, perhaps with new storage
parameters.  With luck, you'll now have a more compressed segment and space
freed at the end of the file.  Resize the data file
to reclaim the space.  Make sure your boss knows you might have to restore
and do a point in time recovery if something goes
wrong.

 10G? Must have a lot of objects not belonging to sys/system in there.
 (Unless someone turned auditing on and forgot about it.) I'd say the
system
 tablespace must be so fragmented that it's best to create another database
 and recreate the users and import their data with default and quota set to
 locally managed tablespace(s).

Other than the SYSTEM tablespace consuming 10Gb of storage, are there any
indications at all that there a performance problem of any kind related to
the purported fragmentation?

Upshot:  if it's not causing any problems, then just live with it; what's
not hurting you isn't hurting you.  Otherwise, if you can see problems
related to data dictionary or if someone desperately wants that tablespace
shrunk from 10Gb to 1Gb or less, then recreate the database...

Thanks Mahu. Do you get the feeling that I might have
done that a few times? ;)

Snapshots and materialized views are the same thing. I
guess I might start calling them materialized views in
the next version or two, but it is so hard to give up
old habits.

Another thing you might need to know - you can't
easily change a job in the Oracle job queue unless you
are the owner, which means that you can't do it as
DBA.

There is a package called dbms_ijob that will allow
you to change jobs as a dba even if you don't own
them. There is usually no public synonym for this
package, so you will have to refer to it as
sys.dbms_ijob. I believe that this package is not
officially supported, so you might not find a lot of
documentation on it, but I have used it for over a
year without any problems.

To turn off a snapshot refresh, use the
sys.dbms_ijob.broken function.

*BE ADVISED*

If you unbreak a job in the Oracle job queue, it will
try to run immediately. This includes snapshot jobs.
If you unbreak a *complete* snapshot refresh job, the
first thing it does is truncate the target table.
Unbreak a complete snapshot refresh job in the middle
of the day and viola, the users suddenly have no data.
Be careful.

 Recreate the snapshot to allow fast refresh, (you
 will
 have to create a snapshot log on your source table)
 and refresh once every 5/10/20/30 minutes.
 
 Fast refreshes are just one commit that is either
 committed or rolled back at the end. Viola, fresh
 data
 instantaneously.
 
 You can do a refresh immediate when you recreate the
 snapshots so it will build the data right away.
 
 To do it really fast, create a new snapshot with the
 correct definition, rename the old snapshot, rename
 the new snapshot to the old name, recompile your
 packages and procedures, drop the old snapshot, and
 viola, new snapshot. 
 
 Snapshots refresh via a job in the Oracle job queue.
 You can adjust timing on this job to adjust your
 refresh frequency.
 
 Make sure you get your indexes, stats, and grants in
 place on the new snap too

Suggestions on MV Implementation !!!!!!!

2002-06-21 Thread Reddy, Madhusudana

Hello All,

I have a set of Materialized views in my DB . we refresh ( COMPLETE) these
MVs, couple of times a day. Web server ( application ) will hit these MVs to
show the data on web pages. But the complete Refresh of MVs are consuming
much time and , at this point of time , Application is not able to show
right data on web pages. This is like a down time. I need some suggestions
from you all, in order to minimize or zeroing this down time.

The first thing I can think of is , FAST refresh , but one of my Sr.DBA told
me that the MV definition will not allow us for a FAST refresh( Are there
any limitations for FAST refresh  ). Here is a sample MV Definition :

CREATE MATERIALIZED VIEW GENRELOB
  NOLOGGING
  BUILD IMMEDIATE
  REFRESH COMPLETE ON DEMAND
  DISABLE QUERY REWRITE
AS SELECT DISTINCT
  '1' AS CLIP, 
  LOB.LOB_ID,
  LOB.LOB_CD,

RE: Suggestions on MV Implementation !!!!!!!

2002-06-21 Thread Reddy, Madhusudana

Thanks DG,
To my understanding from your reply, Can I have a fast refresh on a MV,
which is based on multiple tables , just by having log tables on base tables
of the MV ??

And u also said  You can also set it up so that when anyone makes a change
to the base tables the
MV gets updated as part of their transaction  ... could you please shed
some more light on it ???

Thanks again
Madhu

NB: version of DB is 8.1.7.2

Madhu,

Go tell that SrDBA to go read up on MV's.  They do support a fast
refresh,
but you have to have a log table associated with the base tables in the
view. 
You can also set it up so that when anyone makes a change to the base tables

Jack,
Nice picture of the whole thing .

Through out your solution , mentioned SNAPSHOT , you mean Materialized view
???

Thanks,
Madhu



-Original Message-
Sent: Friday, June 21, 2002 2:33 PM
To: Multiple recipients of list ORACLE-L


Recreate the snapshot to allow fast refresh, (you will
have to create a snapshot log on your source table)
and refresh once every 5/10/20/30 minutes.

Fast refreshes are just one commit that is either
committed or rolled back at the end. Viola, fresh data
instantaneously.

You can do a refresh immediate when you recreate the
snapshots so it will build the data right away.

To do it really fast, create a new snapshot with the
correct definition, rename the old snapshot, rename
the new snapshot to the old name, recompile your
packages and procedures, drop the old snapshot, and
viola, new snapshot. 

Snapshots refresh via a job in the Oracle job queue.
You can adjust timing on this job to adjust your
refresh frequency.

Make sure you get your indexes, stats, and grants in
place on the new snap too. Check your synonyms as
well.

hth,

jack

Rafiq,

I ran your query as we have been in the process of tuning our shared pool,
and I have a question. When you see many more loads than executions for a
given table, is it a safe bet that the application in question is executing
queries that have that table in the from clause, but it is not being used by
that query ? For example, a table has 33 loads and 5 executions. Could I say
that 28 loads were caused by a query that had that table referenced, but not
used (and causing a full table scan, because that's what Oracle does when
you reference, but do not use, a table (in the from clause) ?

Thank you,

RE: Shared Pool Tuneup

2002-05-21 Thread Reddy, Madhusudana

Hamid,
what happens , if an object is getting executed once in a while but takes
huge sharable memory, we may not be getting full use of pinning it in the
shared pool, except wasting the memory, So we need to consider the number of
executions also. if the number of executions are high for any object/SQL,
its good idea to keep it in shared pool.

RE: What makes Export slow ?

Would you post the parameter file ??

Huge Buffer, commit=y, direct=y, assigning the big rollback segment should
help you to have faster export ,
and also you can have a look at the DISK I/O stats ( verify the OFA is same
on both the boxes ).

I moved my database from Solaris 7 to Solaris 8 box (Sun Fire 4800, faster
processors and more memory space)

I create the database with the same script that I used to for my database in
the older machine,

When I export my database from the older machine it was very fast and when I
import to newer machine it was fast too, 

and when I export from new machine it is really slow (very slow), (I am
using same export parameters in both servers)
Can someone help with tuning tips or anything you have... : (

RE: What makes Export slow ?

2002-05-20 Thread Reddy, Madhusudana

The idea of huge rollback segment is just to eliminate the contention the
rollback segment. Well its not always applicable ( possible make sure all
the other applications are not used), but we can create a big rollback
segment and bring it on line and make other rollback segments offline, and
run the export . So definitely the big rollback segment will be used.

COMMIT=Y is not a parameter for export , instead good for import , its my
mistake.

Somewhere I have read that NFS Mounted file system will make the export
slower .

Thanks for your correction,
Madhu

What do you mean assigning the big rollback segment?  How do you do
that to an export and what does it accomplish?

What does COMMIT=Y do in an export?

If I were the original poster, I'd just look at v$session_event for
the export session after several minutes of slowness.

Unix Script --- Archive Log Destination Issue

2002-05-13 Thread Reddy, Madhusudana

Hello All,
I have a script, which cleans up the archive log destination by moving the
old archive logs to a retention area based on the thresholds 
1. Percent of space utilization
2. greater than 2 days old.

The script was working fine , except for the reason , sometimes we see
multiple copies of the same. So I have added the following to code just to
stop multiple copies. But now the script is not running at all and we did
see more than 90% space utilization archive log destination.

Here is the added code:


# Exit If Already Running

function ExitIfAlreadyRunning
{
copies=`ps -ef | grep OraProcessArch | grep $SID_NAME | grep -v grep | wc
-l`
if [ $copies -gt 2 ]
then
   echo $(date) Number Of Copies Running : $copies
   exit 0
else
   return 0
fi
}

Any suggestions ???

I am not  so good in using semaphores and all , looking for a simple
solution if possible ..

Thanks in advance,
Madhu

RE: Re:Import excelfile into Oracle table

2002-04-18 Thread Reddy, Madhusudana



I heard , ( I think in the same list ) ... FILE PATH can be a path to 
your NT local machine too... ( even can have multiple UTL_FILE_DIR locations on 
NT machine )

So we should be able to read a file on NT machine to load the data to the 
Oracle using UTL_FILE package.

RE: datafile sizing ?

2002-04-18 Thread Reddy, Madhusudana

Hello Darren,ROR and all,

How about using locally managed tablespaces and allocating uniform extent
size ( say 4M ) , when we create a tablespace with multiple small datafiles
( say 500 M ) 

I would prefer to have a standard for the size of the datafile .

--Madhu

-Original Message-
Sent: Thursday, April 18, 2002 7:23 AM
To: Multiple recipients of list ORACLE-L


Darren,
 It also depends on the extent sizes you use for the tables in the
tablespace. Will each extent completely use the datafile or will there
be wasted space in the smaller datafiles. As an example: if there is 100
M free space and the extent is 150 M it will not fit in the datafile and
will use the next free space in the new datafile, wasting the 100 M free
space. That can add up to a lot of space over time. 
 Also remember to set the MAXDATAFILE to a limit allowable by the os.
once you reach the limit if it is set small you have to rebuild the
database to raise the limit. Different os's have different limits.

ROR mª¿ªm

 [EMAIL PROTECTED] 04/17/02 08:34PM 
Darren, discuss this with your SA. There may be a limit on the os side
you
need to be aware of.  

Also, consider MTTR.  Seems to me that MTTR won't be that different
between
a 500MB file and a 2GB  file.  

Beyond that, it's your comfort level. Personally I like having larger
files
for ease of administration.

 I am currently building a new 8i database, and have the oppurtunity
to
 consolidate
 some of my datafiles.  In the current configuration I have 4 500Mb

 a tablespace.
 
 Is it okay to create a 2Gb datafile, or am I better off to create 2

Madhu,

Oracle has a fixed (at compile time) (OS) physical blocksize to work with.
That blocksize is basically the minimum blocksize the control file and the
redo log file get accessed in. So by doing 'dbfsize controlfile' you can
see
what the physical blocksize is. Or check from x$kccle.  Now Veritas or the
OS
may have some other ideas what they think is the physical blocksize.

 (1) use show parameter db_block_size or  select name, value from
 v$parameter where name = 'db_block_size'; . I assume your Oracle version
 is
 prior to 9i or has uniform database size.
 (2) Yes, you can. The recovery steps depend on many things:
 - what do you lose; datafile, control file, whole database?
 - how did you make the backup; using RMAN, OS command?
 - your RAID configuration?

And another Question I do have  I have my database running on
WE8ISO8859P9 character set , I am trying to upgrade a 3rd party application
running on the DB and the application document suggests that it expects
WE8ISO8859P1 character set on the database. 

As we know WE8ISO8859P9 is superset of WE8ISO8859P1 , by leaving the
database in the same WE8ISO8859P9 , will it be a problem in future ???
Your suggestions are very much needed .

SEARCH WORDS:
 
adaimgr auto install thread

SOLUTION DESCRIPTION

 
The $OA_JDK_TOP/lib/rt.jar path needs to be included in the
$CLASSPATH environment variable.

The steps taken to solve this problem are as follows:

1. Include the $OA_JDK_TOP/lib/rt.jar path in the $CLASSPATH
   environment variable.

   The $CLASSPATH environment variable resided in the
   $APPL_TOP/admin/adovars.env file, and it is edited by the
   user.  Other variables such as JAVA_TOP, OA_JDK_TOP,
   OAH_TOP, and OAD_TOP are defined also in this file.

2. Export the $CLASSPATH variable to the environment.

3. Invoke the adctrl tool to label the worker that failed as
   Fixed/Restart.

4. Invoke the AutoInstall adaimgr to continue where the
   installation left off.

 Type:  PROBLEM 
 Status:  PUBLISHED 
  Content Type:  TEXT/PLAIN 
 Creation Date:  03-NOV-1999 
 Last Revision Date:  22-JAN-2002 
 
 Problem Description:
 
  
 You are receiving the following warning message when starting a SQL*Plus 
 session:
 
   WARNING-PRODUCT USER PROFILE INFORMATION NOT LOADED 
 
 
 
 If you have run the PUPBLD.SQL script and are still receiving this
 warning, 
 then do the following: 
   
 Connect as user system, drop the PRODUCT_PRIVS view and rerun the
 PUPBLD.SQL 
 script. 
 
  
 Explanation:
 
 
 SQL*Plus reads product restrictions from the PRODUCT_USER_PROFILE table
 when a
 user logs in to SQL*Plus, and maintains those restrictions for the
 duration of
 the session.  Changes to PRODUCT_USER_PROFILE will only take effect the
 next
 time the affected users login to SQL*Plus.  If the PRODUCT_USER_PROFILE
 table is
 created incorrectly, all users other than SYSTEM will see a warning when
 connecting to Oracle from SQL*Plus, that the PRODUCT_USER_PROFILE
 information
 is not loaded.  This message is a warning you that the
 PRODUCT_USER_PROFILE 
 table has not been built in the SYSTEM account.
 
 Running the SQL script PUPBLD.SQL ( or V7PUP.SQL on some platforms)
 will 
 build the PRODUCT_USER_PROFILE table, thus avioding the warning message.

RE: init file ???

2002-04-11 Thread Reddy, Madhusudana

$OH/database is the place where ORACLE will look for the parameter file and
here you can (also) have a soft link created to the Actual location of the
parameter file i.e. . PFILE directory(ORA_HOME/admin/SID/pfile) .

And for the control file location see the initsid.ora file ( parameter
control_file ) and make sure the control files are in proper locations.

Then start the database.

Hi,

I'm using 9.0.1 on win2000.  When a database is
created using configuration assistant, two init files
are created: one in ORA_HOME/database, and the other
in ORA_HOME/admin/SID/pfile.  Here are my questions:

1. what's the difference between these two, why
created two copies.

2. the one in ORA_HOME/database has strange format ef:
*.variable=value, why?

3. how to find out which init file the db is using,
assuming the db cannot be mounted.  I got a problem
that the alert.log keeps telling me the control file
cannot be found.

ORA-00202: controlfile:
'c:\ora_9i\oradata\small\datafile\small.ctl' (I didn't
specify this path in both init file, where did Oracle
get this directory???)

O/S-Error: (OS 2) The system cannot find the file
specified.

Since db is not mounted yet, I cannot use show
parameter pfile.  So how do I know which init file
Oracle is reading?

Thank you!

Leslie

RE: How much space is required for STATSPACK

Yeah I did read all the SPDOC.txt in $ORACLE_HOME/rdbms/admin.
I have created a tablespace of ( a locally managed , uniform , extent size
10 MB ) of size 500 MB , but still getting the below mentioned problem, I
think I have to go for auto extend rather than uniform with 10 MB each. If
you have any suggestions , let me know .

yeah , as you mentioned about the documents which were referred in the LIST
, they are really worth while to read . And I am doing that now.

Hello,

I suggest that you read the readme file for the STATSPACK installation. If
8.1.7, it says that it needs approx. 45MB. You could create a schema, or use
something like TOOLS for the default tblsp, and use TEMP for the temporary
tblsp. Also, I would suggest that you read the articles on STATSPACK on OTN
and elsewhere (I'm pretty sure that someone on this list sent out some nice
URLS about STATSPACK just the other day). Since I was interested, I pulled
the articles, read through them, and did a test install on one of my
development boxes. Also, I suggest that you change the PERFSTAT password.

Thank you,

RE: How much space is required for STATSPACK

seems like I need small extent size , I have given 10MB for each extent ,
and in your case it is just 128 K.
so by reducing the extent size , should it work ?

-Original Message-

It shouldn't take that much space to install. Is CCXSTL01 the correct
tablespace? After you get it installed the space requirement depends on how
many snapshots you take and how long you retain them. I take level 5 snaps
every 15 minutes and actively purge data and rebuild indexes. I retain some
data for 3-7 days and other data for 2 months. With my current snapshot and
purging schedule I'm maintaining an equilibrium of about 250MB for storage.
The extent size for my LMT is 128K.

Perhaps he is not installing as user SYS.  The PERFSTAT user is granted
UNLIMITED tablespace in the install scripts on the tablespace that is
selected, so either there is not enough free space or the grant is bombing
because he is not SYS...or something else that I am not thinking about at
the moment.

Reddy - I assume that you mean that you ran the statsrep.sql and printed the
report. Is your question about interpreting this report? There is a good
series of articles at
http://www.oracle.com/oramag/oracle/00-Mar/index.html?o20tun.html

Or is your question how to write your own queries? If that is the question,
I would recommend that you invest in the book Oracle High-Performance

Don offers some articles on-line at http://www.dba-oracle.com/articles.htm

Let me know if that is the information that you want.

We are periodically getting the;
ORA-1652: unable to extend temp segment by 128 in tablespace TEMP
errors.

I could not identify the problem, so I set up a monitor script which would
insert into a log table space usage records every 30 seconds, so I could see
the space usage at the time of the failure.

After we got another ORA-1652, I looked up the time and queried my log
table, which showed hardly any usage in the TEMP tablespace.

My question is;
Why do I keep getting this error when I have plenty of free space in TEMP???
Why is it trying to extend a 128 extent when I have uniform extents (locally
managed temporary tablespace and the extent sizes are 1M)?

Here are my supporting settings;

Temporary tablespace settings:
create temporary tablespace TEMP 
tempfile '/RPT/oradata04/prddata/temp01.dbf'
size 5000M
REUSE
extent management LOCAL
UNIFORM 
size 1048576;

Query at the time of the failure:
select  sysdate dtstamp,
s.tablespace_name,
d.tbspc_mb,
s.total_blocks*8192/1024/1024 temp_tot_mb,
s.used_blocks*8192/1024/1024 temp_used_mb,
s.free_blocks*8192/1024/1024 temp_free_mb
fromv$sort_segment s,
(select tablespace_name,sum(bytes/1024/1024) tbspc_mb
from dba_data_files
group by tablespace_name
union
select tablespace_name,sum(bytes/1024/1024) tbspc_mb
from dba_temp_files
group by tablespace_name) d
where s.tablespace_name=d.tablespace_name;

Output:

from v$sort_usage u,

where s.saddr = u.session_addr 
and a.address (+) = s.sql_address

group by
