ORA-1575
Hi All, Oracle 8.0.5 AIX 4.3.3 We have a database that showed an ORA-1575 every minute for 30 minutes this morning. This was just after startup when a whole bunch of batch processes kick in as well Documentation just says retry the operation (smon tried every minute and eventually succeeded) * ORA-01575 timeout waiting for space management resource Cause: Failed to acquire necessary resource to do space management. Action: Retry the operation. ** My feeling is that I can safely dismiss the idea that this is a serious matter, but would like to run this one by you guys as I have not had this before.

SAN
All I have a meeting tomorrow where I am going to point out why SAN and Oracle does not go very well together. Here are my thoughts. Can you pick holes in this argument, modify it or suggest any changes TIA Babu SAN and Oracle ? Conflicting IO behavior * There are four types of IO in Oracle 1.Random Reads (RR) ? DBWR - Using indexes 2.Sequential Reads (SR) ? DBWR - Full table scans 3.Random Writes (RW) ? DBWR ? Writing dirty blocks 4.Sequential Writes (SW) ? LGWR, Arch ? Writing redo logs and Redo Archival + Control files * Bulk of any Oracle database's IO is done in RR, SR and RW. If SW is very high it denotes configuration problems. * SAN (or for that matter any RAID device) is configured for writing or reading large chunks at a time. The stripe size on most SANs and RAID devices are 256K or more. Compare this to the Oracle block size of 4k/8k in most databases (going upto 32K in datawarehouses) * SANs do *Read Ahead*. If one block is requested, they read more than one blocks *while at the disk* hoping that the same process will request the other blocks some time soon. Here is the conflict. * When ever Oracle does a RR, SR or RW it writes randomly and not sequentially. It will read/write a particular block at a time in case of RR and RW and 'x' blocks (where x = dbfile_multi_block_read_count) in case of SR. Therefore only during SR will Oracle use the entire stripe width. In all other cases, The difference in the stripe width and db_block_size will be excess IO. * Why *read ahead* will cause a conflict : * The internal structure of a datafile could be as follows. The file consists of 10 blocks. These are occupied by 3 tables. The blocks shown below are numbered using table_name.block_number |-+-+-+-+-+-+-+-+-+-| | | | | | | | | | | | | | 1.1 | 1.2 | 2.1 | 3.1 | 3.2 | 3.3 | 2.2 | 1.3 | 2.3 | | 3.4 | | | | | | | | | | | | | |-+-+-+-+-+-+-+-+-+-| * The first block on the datafile is the first block of table 1, second block is the second block of table 1, the third block is the first block of table 2 and so on.. (For simplicity sake, I am assuming Oracle will allocate space in blocks and not in extents) * Now assume Oracle requests the first block of table 1. Assume read ahead is set to three blocks (three blocks will be read instead of 2 blocks). In this case the SAN will read 2.1, 3.1,3.2. * The blocks 3.1 and 3.2 will be entirely useless as Oracle is never going to read it. SAN cannot tell that the block 2.2 that Oracle might possible request next is the 7th block in the datafile and so it can never *read ahead* intelligently. Why the buffer of SAN has very little impact w.r.t Oracle read performance? * Oracle has its own buffering for all IO types * DBWR reads and writes uses the DB Buffer Cache * LGWR uses the Log buffer * Db buffer Cache is managed by a LRU Algorithm (Touchcount from 9I). * Bulk of the IO done by Oracle is Logical IO (LIO) and not Physical IO (PIO). * Assume the buffer cache hit ratio is 80%. This means that only 20% of the IO calls are PIO. Only 20% of the calls ever hit the SAN's cache. Since this 20% is probably the least requested/never requested data (going by Oracle's LRU algorithm) , its quite likely that the SAN's buffers don't have this either. * Given that Oracle is going to cache even this 20% in its buffers, the next PIO call is going to be for something totally different ? which is not there in the SAN's buffer. * Couple this with the read-ahead (discussed earlier), Our SAN's buffer is now populated with lots of data that Oracle might never use a PIO to retrieve. * Thus the SAN's buffer can never really provide to Oracle the data it reads most ? Its already there in Oracle. To be fair, SAN's huge buffers will come as a boon to small databases ? where the entire database can be cached in the SAN's buffers. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: INET: [EMAIL PROTECTED] Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051 San Diego, California-- Public Internet access / Mailing Lists To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).

Re: Explain Plan Question
No, it isn't correct. Explain plan gives you precisely what it should, and that is the access plan. Here is an excerpt from the documentation: The EXPLAIN PLAN statement displays execution plans chosen by the Oracle optimizer for SELECT, UPDATE, INSERT, and DELETE statements. A statement's execution plan is the sequence of operations Oracle performs to run the statement. The row source tree is the core of the execution plan. It shows the following information: * An ordering of the tables referenced by the statement * An access method for each table mentioned in the statement * A join method for tables affected by join operations in the statement * Data operations like filter, sort, or aggregation In addition to the row source tree, the plan table contains information about the following: * Optimization, such as the cost and cardinality of each operation * Partitioning, such as the set of accessed partitions * Parallel execution, such as the distribution method of join inputs *** So, running the explain plan takes into account nothing. It displays the chosen access path. If you're not satisfied, you can always use subtle hints. Oracle optimizer takes everything into account and always gives you the ideal execution plan (or at least, it will, starting with the version 99i).

EMC and AIX resources
I'll be starting a new job next month and consequently starting at the beginning of a learning curve for some products. Just wondering if anyone has any good resources or comments for what to watch for with AIX (most of my experience so far has been with Sun Solaris. I do know about http://bhami.com/rosetta.html ), and EMC Symmetrix. I know I've seen a bunch of comments in the past of DBA vs SA preferences with EMC, but I haven't saved them (time to hit the archives). Thanks. Henry
Use Raw partition or LVM in rac installation?
hi, I am trying to setup a RAC database with two DELL 6650 and a disk array, with two eth card, one for public network and the other for heart beating message and sga data transfer. I have two questions: 1. For oracle ceritified combinations, there should be 2 gigabytes network card and one fiber channel switch , which is used to transfer sga data between instances. In my case, i do not have more than 2 nodes, so i directly interconnect the two nodes with general network line, is it ok to let it work with the cache fusion? 2. I am using redhat advanced server, and i am not familier with this product. In my default installation, there is no LVM manager. I read several document talking about install RAC on linux, all using LVM manager. So, shall i use logical volumn manager, or directly use raw partitions? Thanks for your advice.

T3's, NetApps, Tuning, Wife's Opinion and other fun
Hi All, Well after 6 wekks of testing here is the basic way to operate SUN T3's as efficiently as possible. Be prepared for arguments with High priests from the cult of SAME. SUN T3's are fiber attached hardware RAID 5 arrays with a "modern cache". The hardware engineers argue that if you need more I/Os/sec just add another array as a "concatenated volume". The theory being the hardware is intelligent enough to use the cache to increase throughput. It actually works as they claim. Never did explain why it wasn't a single point of failure in the end though. My hardware was 3 4810's, each with 4 - 8 cpus, each with 4 - 8GB, 2 - 4 bricks per machine First insist that multiple bricks be mounted on at least 2 mount points. (D2 and D3). DO NOT USE the forcedirectio option. I don't know why but I have been unable to take less than a 40% throughput hit with it turned on. And I don't care what other people say, no matter how much respect I have for them Insist on at least one JBOD for oracle binaries and configs Insist on at least one JBOD for redo logs (D1) This a bare minimum. One set of redo on D1 One set of redo on D2 Archive logs, Rollback and Temp on D3 All data files where needed on D2 Next Level up Add another JBOD for redo and move redo on to it Move Rollback and Temp to D2 At this point to get more throughput you have to take the JBOD to raw devices. Or try forcedirectio on these devices :) If even better performance is needed, more JBOD, for rollback and redo. If more disk spaces is needed, get another brick. Which leads me to the recent discussion on "proper way to tune" Huh? Why make it so complex?

RE: Houston, do I have a problem?
Rachel, This has not gotten to the level of getting it in 'black & white' or to the 'beating' level, yet. That's why my boss wanted to just review the database and see if this thing will scale when we add more Applications and of course, hundreds of more users. More digging will be required to find problematic areas, if any, and if some one complains that there is such-and-such problem. Currently, no one is complaining, as the batch processes finish while we are asleep and the on-line load has been pretty light. But there is no guarantee that it will be so in the near future. And looking at this database at this time was a good idea from my boss, and getting someone else, (not the primary/secondary DBA) to do that is even better (for him, that is ;) Thanks. - Kirti -Original Message- Sent: Sunday, August 11, 2002 8:38 PM To: Multiple recipients of list ORACLE-L Kirti, Get it in WRITING that you are not allowed to change anything.

Greg, That's exactly the problem--you can't tell whether it's a problem or not! If the instance has been up for a couple of days, then it's probably a big deal. If the instance has been up for several months, then it's probably far less of a big deal. ...Unless a disproportionate amount of all that waiting time has been inflicted upon a really small number of programs.

RE: Houston, do I have a problem?
Cary, Thank you very much for a wonderful response. I have not yet talked to any users or developers regarding the performance of this database. I just shared with my boss (and with the list) what I found in my brief 'review' of the database. There are no reported performance related problems that need to be fixed right away. But he was concerned as we will be loading this database soon to support a couple of more Applications. One of which will have more OLTP transactions than the other. Currently the database has heavy DML activity only during the batch processes. There is very minimal DML via on-line (Intranet). From our auto-scheduler (AutoSys) system, I have found out that there are a *number* of batch jobs that run *concurrently* against this database in the batch window. That would be the next area to 'review' as to what these jobs do and how they do it. For all we know, it could just be a scheduling problem! I am not paying much attention to the stats at system level as they do not mean much, at this time. I will be watching the batch processes and most probably consider using Statspack and make use of Sparky (http://www.hotsos.com/products/sparky/) to dig deeper. I am not going to reach any conclusion based solely on what I saw in v$system_event. That was just my first step to see what kinds of waits this database had encountered, just as some check the hit ratio first ;-) But I must say, based on those stats, that the I/O subsystem is being stressed quite a bit. Regards, - Kirti -Original Message- Sent: Monday, August 12, 2002 1:38 AM To: Multiple recipients of list ORACLE-L This is an interesting report. I think the responses to it are even more interesting. One response admits confusion (which I think is a completely fair reaction). Another zeroes in knowingly on some specific details. If everyone had time to respond, I would expect a rash of differing opinions about what you should do first to fix this system... This kind of game is a fundamental part of using system-wide performance data. (The various ratio problems are just as relevant for system-wide data collected from the "wait interface" as they are from v$sys.) Don't lose hope if you look at Kirti's note and wonder, "so what's the point?" You cannot see everything that's wrong with a system from a report like this. I think in fact that you can know only two things from a v$system_event report: 1. If you know the "secret constants" (see www.hotsos.com/dnloads/1/constants), then you can see whether the database is spending heinously longer than "normal systems" at doing things. In this report, I would propose that an average single-block read latency of 9.7 seconds (977.107332 centiseconds), for example, is "heinously longer than normal." 2. If you know the "secret list" of things that databases should and shouldn't do, then you can see whether a database is doing a lot of things that it "shouldn't be doing." Databases, for example, shouldn't need to wait very often for 'buffer busy waits' waits, 'enqueue' waits, or 'latch free' waits. (Where's the url for *this* secret list? It's so simple that you don't really need one. Database should spend most of their time either idle, providing CPU service, or doing physical I/O. Not much else.) Sure, knowing these two things is worth something, but it leaves lots of good questions unanswered (*essential* questions, actually): a. Even if an Oracle kernel event is consuming "heinously longer-than-normal" elapsed times, or even if it is called "heinously too often," does it really matter? What if the event is called predominantly by unimportant business processes, and the long latencies don't impact anything important? Then you would be wasting your time fixing it (instead of fixing something important first). If you assume an event is important because it's prominent in a system-wide data collection and you then fix a huge performance problem, then you were actually just lucky. It won't happen this way every time. b. What if the database is providing the "right kinds of service in the right proportions?" How can you tell whether it's spending more time than it *could* have spent? For example, just because a program spends 90% of its response time on the CPU and 10% on a disk (kind of a "normal, healthy" profile), it is *not* okay if the response time is 10 hours when it should be 6 seconds. It's not the proportions that are important; it's the absolute response time. So... Is the HDS disk array a problem? Probably. But, it's possible--*likely*, actually--that an analyst could fix all the problems shown here and still have really slow applications. Why? Because several essential-but-slow programs on this system might not spend significant amounts of their response time waiting on any of the top 10 events in this list. We see it pretty often: people fix their system's "worst performance problems" and then find out that their work really didn't make a noticea

Re: Oracle vs. DB2
For what I've read, globally the 2 databases are equal in performance, reliability and functionnalities. Larryh E as many times said that it's only competition in the database market is DB2. I guess it really depends on your environment. Of course Oracle works on more OS (used to be anyway), but which big organisation only have one DB ? All big companies I've worked have many DB.

[no subject]
Hello,
I have a question regarding method of index access(full vs. range) that
oracle uses when I use different join methods (Hash vs. Nested loop).
Here are the some details about the environment.
Server : Oracle Server EE ver 8.1.7.2
OS : HP UX 11.0
hash_area_size : 4194304
hash_join_enabled : TRUE
hash_multiblock_io_count: 64
The tables, indexes are all analyzed fully (no estimates) with dbms_stat.
The following two scenarios are executed back-to-back and are reproducable.
The parameter value to the SQL could be any month in a format like 200207,
200201 etc..
When I use nested loop join the index on large table is ranged scaned, but
when I use the hash join the full scan on the index is done. My question is
why is the behviour of index scan different? Why there is no partition
pruning when the table is hash-joined?
The details related to the objects is at the end of the message.
Thanks for your help.
Regards
Viral.

RE: Delete performance
Title: RE: Delete performance I would use your method to CTAS but combine it with partitioning in order to overcome the unavailability issue. The new table would be a single-partition (MAXVALUE) object that would enable the use of EXCHANGE feature. I posted a nugget a while back describing the use of a one-partition table (and indexes) and then swapped the underlying segment with a normal table on the fly. The catch is the licensing cost for partitioning. But we already had it for it's intended use and this "availability" feature was icing on the cake. This method is replaced by 9i's online reorg feature but we got a good 3 years out of it. Tony Aponte Home Shopping Network, Inc. -Original Message- From: Tim Gorman [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 01, 2002 4:29 PM To: Multiple recipients of list ORACLE-L Subject: Re: Delete performance If the table can be "unavailable" for a very brief period of time while this is happening, I'd suggest performing a PARALLEL NOLOGGING CREATE TABLE AS SELECT to perform this mass deletion. Use a WHERE clause in the SELECT portion of the CTAS that picks up all the rows you want to keep, which is the logical negation of the WHERE clause you already have for the DELETE. Advantages: faster (INSERT operations are always faster than UPDATE or DELETE), using NOLOGGING is possible (faster, reduce overall impact on system), no undo is generated (faster, reduce one possible point of failure), and if you had any ambitions to re-build the table (i.e. get rid of chained rows, move to locally-managed tablespace), that gets done too. Same for the associated indices (rebuild them in parallel, nologging, compute stats). Also, the original table can be renamed and saved in case it's ever needed (for fast "rollback", for example)... Disadvantages: if table cannot be unavailable for the last-second RENAME operation when the "old" table is swapped for the "new", which would invalidate any associated PL/SQL stored objects and open cursors, then this won't work. However small that window of unavailability may be, sometimes you just can't go there...

RE: Houston, do I have a problem?
Cary, Thank you very much for a wonderful response. I have not yet talked to any users or developers regarding the performance of this database. I just shared with my boss (and with the list) what I found in my brief 'review' of the database. There are no reported performance related problems that need to be fixed right away. But he was concerned as we will be loading this database soon to support a couple of more Applications. One of which will have more OLTP transactions than the other. Currently the database has heavy DML activity only during the batch processes. There is very minimal DML via on-line (Intranet). From our auto-scheduler (AutoSys) system, I have found out that there are a *number* of batch jobs that run *concurrently* against this database in the batch window. That would be the next area to 'review' as to what these jobs do and how they do it. For all we know, it could just be a scheduling problem! I am not paying much attention to the stats at system level as they do not mean much, at this time. I will be watching the batch processes and most probably consider using Statspack and make use of Sparky (http://www.hotsos.com/products/sparky/) to dig deeper. I am not going to reach any conclusion based solely on what I saw in v$system_event. That was just my first step to see what kinds of waits this database had encountered, just as some check the hit ratio first ;-) But I must say, based on those stats, that the I/O subsystem is being stressed quite a bit. Regards, - Kirti -Original Message- Sent: Monday, August 12, 2002 1:38 AM To: Multiple recipients of list ORACLE-L This is an interesting report. I think the responses to it are even more interesting. One response admits confusion (which I think is a completely fair reaction). Another zeroes in knowingly on some specific details. If everyone had time to respond, I would expect a rash of differing opinions about what you should do first to fix this system... This kind of game is a fundamental part of using system-wide performance data. (The various ratio problems are just as relevant for system-wide data collected from the "wait interface" as they are from v$sys.) Don't lose hope if you look at Kirti's note and wonder, "so what's the point?" You cannot see everything that's wrong with a system from a report like this. I think in fact that you can know only two things from a v$system_event report: 1. If you know the "secret constants" (see www.hotsos.com/dnloads/1/constants), then you can see whether the database is spending heinously longer than "normal systems" at doing things. In this report, I would propose that an average single-block read latency of 9.7 seconds (977.107332 centiseconds), for example, is "heinously longer than normal." 2. If you know the "secret list" of things that databases should and shouldn't do, then you can see whether a database is doing a lot of things that it "shouldn't be doing." Databases, for example, shouldn't need to wait very often for 'buffer busy waits' waits, 'enqueue' waits, or 'latch free' waits. (Where's the url for *this* secret list? It's so simple that you don't really need one. Database should spend most of their time either idle, providing CPU service, or doing physical I/O. Not much else.) Sure, knowing these two things is worth something, but it leaves lots of good questions unanswered (*essential* questions, actually): a. Even if an Oracle kernel event is consuming "heinously longer-than-normal" elapsed times, or even if it is called "heinously too often," does it really matter? What if the event is called predominantly by unimportant business processes, and the long latencies don't impact anything important? Then you would be wasting your time fixing it (instead of fixing something important first). If you assume an event is important because it's prominent in a system-wide data collection and you then fix a huge performance problem, then you were actually just lucky. It won't happen this way every time. b. What if the database is providing the "right kinds of service in the right proportions?" How can you tell whether it's spending more time than it *could* have spent? For example, just because a program spends 90% of its response time on the CPU and 10% on a disk (kind of a "normal, healthy" profile), it is *not* okay if the response time is 10 hours when it should be 6 seconds. It's not the proportions that are important; it's the absolute response time. So... Is the HDS disk array a problem? Probably. But, it's possible--*likely*, actually--that an analyst could fix all the problems shown here and still have really slow applications. Why? Because several essential-but-slow programs on this system might not spend significant amounts of their response time waiting on any of the top 10 events in this list. We see it pretty often: people fix their system's "worst performance problems" and then find out that their work really didn't make a noticea

also added the row spacing here for clarity.The dev would like the group
of WO W858835, rows 10 and 11, immediatelyafter WO group W838796 because the
groups have the same number of rows (RC)and same values of CP within the
groups.MIN and MAX would work in this case, but if the groups are larger
than twoit's no guarantee of order. What I was thinking is a report
column thatwould be the concatonation of all the CPs for the group, but

SAN issues
All I an trying to get our management understand the issues related to SAN. These are my thoughts. Let me know what you think about it... (PS : Apologies if you recv this twice. I posted it but I never saw it come through the list and so I posted again) Babu SAN Issues SAN and Oracle ? Conflicting IO behavior ® There are four types of IO in Oracle 1.Random Reads (RR) ? DBWR - Using indexes 2.Sequential Reads (SR) ? DBWR - Full table scans 3.Random Writes (RW) ? DBWR ? Writing dirty blocks 4.Sequential Writes (SW) ? LGWR, Arch ? Writing redo logs and Redo Archival + Control files ® Bulk of any Oracle database's IO is done in RR, SR and RW. If SW is very high it denotes configuration problems. ® SAN (or for that matter any RAID device) is configured for writing or reading large chunks at a time. The stripe size on most SANs and RAID devices are 256K or more. Compare this to the Oracle block size of 4k/8k in most databases (going upto 32K in datawarehouses) ® SANs do "Read Ahead". If one block is requested, they read more than one blocks "while at the disk" hoping that the same process will request the other blocks some time soon. Here is the conflict. ® When ever Oracle does a RR, SR or RW it writes randomly and not sequentially. It will read/write a particular block at a time in case of RR and RW and 'x' blocks (where x = dbfile_multi_block_read_count) in case of SR. Therefore only during SR will Oracle use the entire stripe width. In all other cases, The difference in the stripe width and db_block_size will be excess IO. ® Why "read ahead" will cause a conflict : ® The internal structure of a datafile could be as follows. The file consists of 10 blocks. These are occupied by 3 tables. The blocks shown below are numbered using table_name.block_number |-+-+-+-+-+-+-+-+-+-| | | | | | | | | | | | | 1.1 | 1.2 | 2.1 | 3.1 | 3.2 | 3.3 | 2.2 | 1.3 | 2.3 | 3.4 | | | | | | | | | | | | |-+-+-+-+-+-+-+-+-+-| ® The first block on the datafile is the first block of table 1, second block is the second block of table 1, the third block is the first block of table 2 and so on.. (For simplicity sake, I am assuming Oracle will allocate space in blocks and not in extents) ® Now assume Oracle requests the first block of table 1. Assume read ahead is set to three blocks (three blocks will be read instead of 2 blocks). In this case the SAN will read 2.1, 3.1,3.2. ® The blocks 3.1 and 3.2 will be entirely useless as Oracle is never going to read it. SAN cannot tell that the block 2.2 that Oracle might possible request next is the 7th block in the datafile and so it can never "read ahead" intelligently. Why the buffer of SAN has very little impact w.r.t Oracle read performance? ® Oracle has its own buffering for all IO types ® DBWR reads and writes uses the DB Buffer Cache ® LGWR uses the Log buffer ® Db buffer Cache is managed by a LRU Algorithm (Touchcount from 9I). ® Bulk of the IO done by Oracle is Logical IO (LIO) and not Physical IO (PIO). ® Assume the buffer cache hit ratio is 80%. This means that only 20% of the IO calls are PIO. Only 20% of the calls ever hit the SAN's cache. Since this 20% is probably the least requested/never requested data (going by Oracle's LRU algorithm) , its quite likely that the SAN's buffers don't have this either. ® Given that Oracle is going to cache even this 20% in its buffers, the next PIO call is going to be for something totally different ? which is not there in the SAN's buffer. ® Couple this with the read-ahead (discussed earlier), Our SAN's buffer is now populated with lots of data that Oracle might never use a PIO to retrieve. ® Thus the SAN's buffer can never really provide to Oracle the data it reads most ? Its already there in Oracle. ® To be fair, SAN's huge buffers will come as a boon to small databases ? where the entire database can be cached in the SAN's buffers. SAN or no SAN ? Why will performance be affected if we have indexes and tables on the same disk ® Lets forget all this buffering, caches etc. Assume we have 10 disks in two LUNs. Both the LUNs share the 10 disks. Each of this LUN is made visible to Unix as a mountpoint. The DBA uses one mountpoint for indexes and one mountpoint for tables. ® Since we have used all the 10 disks for both the LUNs, the structure of one disk can look like this. The first two blocks are a chunk of LUN1 where we have the table TAB1. The next three blocks
Re:set sql*trace VB/Crystal
Barb, More than likely VB is spawning Crystal in a separate database session, therefore the alter session command will not work. You could have her start the report & then use top sessions to extract the sql and explain plan from the DB. Or you could extract the sql from the crystal report & go from there.

OPS 7.3.4 - how to ?
Dear gurus ! I have to create an OPS 7.3.4 database (yes, there are still Oracle7 installations out there). Actually we are migrating our current OPS DB to another storage (EMC). So , the software is installed , i just need to create the DB. I can not find which scripts to run after the "create database" (i.e. catproc.sql , catexp.sql). Does anyone have a list of such scripts to run for OPS , please? Also , are there any known gotchas for OPS 7.3.4 setup ? I plan to export the exisiting DB, to create the new DB (with the same name of the DB and the instances as the original ones) and then to import. Is it OK ? TIA.

RE: SQL*Loader : How can I load the Line Feed as part of data
Hi Rachel,
I have attached the sample data and controlfile, which we are using to load the data.
It is loading the line feed characters('\x0d\x0a') as it is. Oracle should store it as
Line Feed while loading through SQL*Loader.
When I select this column it should displays something like this. i.e. a line feed
instead of \x0d\x0a.
But currently it does not happen that way as SQL*Loader loads '\x0d\x0a' as it is.
I may be missing something. I searched in manual and Metalink but not able fix my
problem.
Thanks,
Ashoke
When the test is conducted in the Atrium, this parameter encodes to Manual Therapy 50
Hz Induction Atrial Pacing Minimum Interval and
Manual Therapy Atrial 50 Hz Induction Instruction Buffer Byte 7 and 9.\x0d\x0a
When the test is conducted in the Ventricle,this parameter encodes to Manual Therapy

Manual Therapy 50 Hz Induction Instruction Buffer Byte 3 and 5. and when we select

check the utilities documentation, specifically the Field List section
and the "terminated by" clause.. you can override the default
terminator of line feed. You can also concatenate multiple lines
together

What is your goal? Are you just trying to create a test database, or trying to perform a disaster recovery test? For creating a test database, take a look at the RMAN DUPLICATE command. As to your specific question of changing the file path, the RMAN SWITCH command should be able to do what you need. Another idea is to have your Unix system administrator create the file paths you need so that you don't have to perform any changes in RMAN. For example, if you need a path /u01, create a file path or mount point with that name on the test system. One less thing to wrestle with in RMAN. I do not find that RMAN takes kindly to changes.

Re: RMAN: How to restore backup to a different box
Check the RMAN docs; the process for doing this is well described there. Basically, you either use a parameter in the init file (when you can do wildcard path changes) or use set commands in the rman recover script.

Re: interMedia Text
As you are running 8.1.7 you should not need the extproc_connection_data entry. What you need is that the LD_LIBRARY_PATH includes $ORACLE_HOME/ctx/lib in the environment *before* you start the Listener. The listener.ora entries are the regular entries for the database SIDs.

I cannot file a backport request as 8.0.4 is desupported. However you can use the workaround as below 1) Create a Database link from the 8.1.x db to the 8.0.x db using 'CREATE DATABASE' ie: SQL> create database link connect to identified by 2) Create a new table using 'CREATE TABLE' ie: SQL> create table as select * from @ or 2) Insert data into an existing table using 'INSERT' ie: SQL> insert into select * from @ Regards, Anil Oracle Support Services Bookmark Fixed font Go to End Doc ID: Note:110364.1 Subject: Workaround for ORA-1002 on COPY COMMAND from 8.Xto 8.X Type: PROBLEM Status: PUBLISHED Content Type: TEXT/PLAIN Creation Date: 26-MAY-2000 Last Revision Date: 22-JAN-2002 Problem Description: You are using the COPY command to copy data from one 8.x database to another 8.x database. You receive an ORA-01002 error. ORA-01002: fetch out of sequence Cause: This may be caused by fetching from a 'select for update' cursor after a commit. A PL/SQL cursor loop implicitly does fetches and may also cause this error. You see there are several bugs on the issue but not all of them are included in patchsets or have fixes. In this example you are using COPY from 8.1.6 to 8.0.6: Testcase: SQL> select INSTANCE_NAME from v$instance; INSTANCE_NAME V816 SQL> select INSTANCE_NAME from v$instance@V806; INSTANCE_NAME V806 SQL> copy from [EMAIL PROTECTED] - > insert copy2 using select * from copy1; select * from copy1 * Error in SELECT statement: ORA-1002: fetch out of sequence Solution Description: = Use the following Workaround: 1.

To: Multiple recipients of list ORACLE-L
The original question on this thread was for an automated "purge" for
STATSPACK. I wrote this stored procedure based on the v8.1.7 version of the
standard "sppurge.sql" script. I'd use that script, except I don't like the
way it is called (i.e. range of SNAP_IDs). This stored procedure figures
out the range of SNAP_IDs based on the parameter indicating the number of
days of data to retain...
Hope this helps -- as always, no warranties!

script --
/**
* File: sppurpkg.sql
* Type: SQL*Plus script
* Author: Tim Gorman (Evergreen Database Technologies, Inc.)
* Date: 18Oct01
*
* Description:
* SQL*Plus script containing DDL commands to create the package
* SPPURPKG, intended for use with STATSPACK from Oracle database
* versions 8.1.7 and above. Adapted from the "sppurge.sql" script
* which is included with standard STATSPACK v8.1.7, it is easier
* to use because it can be called automatedly from the DBMS_JOB
* package (instead of interactively as with "sppurge.sql") and it
* takes only the number of days of STATSPACK data to retain
* (instead of prompting for a begin/end range of SNAP_IDs, like
* "sppurge.sql")
*
* After the package is created, then this script will submit the
* procedure "SPPURPKG.RUN(14)" (i.e. purge data older than 14
* days) to run once per day. You may want to modify this,
* depending on the volume of activity on the database(s) being
* monitored by STATSPACK and the amount of storage you are
* prepared to allocate to the PERFSTAT schema...

RE: Houston, do I have a problem?
Cary, Your last paragraph is *GREAT* advice. Every DBA should take it out, print it large, and paste it to the top of their screen. Focusing first on the highest priority item in the business model will win you the biggest supporters in the organization. Tom Mercadante Oracle Certified Professional -Original Message- Sent: Monday, August 12, 2002 2:38 AM To: Multiple recipients of list ORACLE-L This is an interesting report. I think the responses to it are even more interesting. One response admits confusion (which I think is a completely fair reaction). Another zeroes in knowingly on some specific details. If everyone had time to respond, I would expect a rash of differing opinions about what you should do first to fix this system... This kind of game is a fundamental part of using system-wide performance data. (The various ratio problems are just as relevant for system-wide data collected from the "wait interface" as they are from v$sys.) Don't lose hope if you look at Kirti's note and wonder, "so what's the point?" You cannot see everything that's wrong with a system from a report like this. I think in fact that you can know only two things from a v$system_event report: 1. If you know the "secret constants" (see www.hotsos.com/dnloads/1/constants), then you can see whether the database is spending heinously longer than "normal systems" at doing things. In this report, I would propose that an average single-block read latency of 9.7 seconds (977.107332 centiseconds), for example, is "heinously longer than normal." 2. If you know the "secret list" of things that databases should and shouldn't do, then you can see whether a database is doing a lot of things that it "shouldn't be doing." Databases, for example, shouldn't need to wait very often for 'buffer busy waits' waits, 'enqueue' waits, or 'latch free' waits. (Where's the url for *this* secret list? It's so simple that you don't really need one. Database should spend most of their time either idle, providing CPU service, or doing physical I/O. Not much else.) Sure, knowing these two things is worth something, but it leaves lots of good questions unanswered (*essential* questions, actually): a. Even if an Oracle kernel event is consuming "heinously longer-than-normal" elapsed times, or even if it is called "heinously too often," does it really matter? What if the event is called predominantly by unimportant business processes, and the long latencies don't impact anything important? Then you would be wasting your time fixing it (instead of fixing something important first). If you assume an event is important because it's prominent in a system-wide data collection and you then fix a huge performance problem, then you were actually just lucky. It won't happen this way every time. b. What if the database is providing the "right kinds of service in the right proportions?" How can you tell whether it's spending more time than it *could* have spent? For example, just because a program spends 90% of its response time on the CPU and 10% on a disk (kind of a "normal, healthy" profile), it is *not* okay if the response time is 10 hours when it should be 6 seconds. It's not the proportions that are important; it's the absolute response time. So... Is the HDS disk array a problem? Probably. But, it's possible--*likely*, actually--that an analyst could fix all the problems shown here and still have really slow applications. Why? Because several essential-but-slow programs on this system might not spend significant amounts of their response time waiting on any of the top 10 events in this list. We see it pretty often: people fix their system's "worst performance problems" and then find out that their work really didn't make a noticeable end-user impact. (I'm confident that Kirti won't end up in this trap, but that's because I trust him to exercise intuition and experience far beyond the scope of what can be learned from his v$system_event data.) The "wait interface" is an important tool, because it "finally" (well, since over ten years ago) allows us to see where a program spends its time. But to use that tool to see how a whole system has spent its time since instance startup has the same limitations as any other method that relies upon system-wide aggregated data. So, what should you look at to avoid performance improvement project ambiguities? Session-level data. Which session? As I mentioned last week, I believe the analyst should focus first upon sessions whose performance improvement would most significantly improve the business. That, in my opinion, is The Big Secret.

RE: Physical Database Layout
Hi Manav, Sorry for a late reply. Actually I had left it for gurus to reply, and moreover I was enjoying the weekends! Since you are working on enterprise application, surely the organization which will use u application will have a DBA. So you only need to be concerned about the table structure, because all other things(relatd to physical layout of the DB) can be changed during installation time. Still just for ur knowledge a few pointers(a bit simplified). Again not an exhaustive list, just a few things which immediately come to my mind: * Always use Locally Managed Tablespaces(saves a lot of headache) * Try to spread ur data evenly to different tablespaces, so that those tablespaces can be on different disks * Keep index and data seperate * DB block size depends upon the data the queries are supposed to fetch. Larger the data more the DB Block size, lesser the data, smaller the block size * Don't worry about things like rollback segments because they can be added later by the production DBA * If your DB is going to be used more for insert/updates rather than for queries, use less indexes as indexes have an overhead while insert/update/delete * Write queries carefully, Use bind variables as much as possible. Read a bit about SQL tuning to know more abt the art of writing queries HTH Naveen -Original Message- Sent: Saturday, August 10, 2002 10:04 PM To: Multiple recipients of list ORACLE-L Hi Naveen, Thanks for taking the time out to reply. Yes I agree most of the programmers do not bother even to optimize the queries they write, but things get a tad complicated when you are responsible for an enterprise application and you are concerned with each aspect of the system. I understand optimization is an iterative process, but unless the physical layout of the DB itself is not right, the iterative cycle of optimization will not result in too much of an improvement. What i am looking for is a set of directives that need to be considered during the physical design, such as whether to use local tablespaces, the number of rollback segments, db block size, etc..

interMedia Text
Dear List, We have :- Solaris SunOs 5.8, Oracle 8.1.7 I have created three databases using the dbassist tool and I included, as one of the installation options, InterMedia. Having read the installation guides (including post installation for Oracle InterMedia) and the Oracle interMedia Text - 8.1.5 Overview "Post Installation Setup" I have the following questions :- 1) Having amended the "listener.ora" and "tnsnames.ora" files I'm not sure if I have done this correctly because the "Post Installation Setup" refers to adding ONE entry (for extproc_connection_data) in the tnsnames.ora file for A database. But I have three, so I have entered this SID specific info. three times, is this correct ? 2) Having amended the listener.ora file to contain three extra entries is this correct ? 3) I remember one of the NET8 classes I took, where the instructor insisted that we amend these files with great caution and in particular to the layout of entries. e.g. the number of spaces etc. etc. Well the new entries I added don't conform exactly to the already existing entries, here is a snip of my listener.ora file SID_LIST_LISTENER (SID_LIST (SID_DESC (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (PROGRAM = extproc) ) (SID_DESC (GLOBAL_DBNAME = RATREP) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (SID_NAME = RATREP) ) (SID_DESC (GLOBAL_DBNAME = CQPROD01) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (SID_NAME = CQPROD01) ) (SID_DESC (GLOBAL_DBNAME = CQTEST01) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (SID_NAME = CQTEST01) ) (SID_DESC = (SID_NAME = ep_agt1) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (ENVS = LD_LIBRARY_PATH=/u01/app/oracle/product/8.1 7/ctx/lib) (PROGRAM = extproc) ) (SID_DESC = (SID_NAME = ep_agt2) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (ENVS = LD_LIBRARY_PATH=/u01/app/oracle/product/8.1 7/ctx/lib) (PROGRAM = extproc) ) (SID_DESC = (SID_NAME = ep_agt3) (ORACLE_HOME = /u01/app/oracle/product/8.1.7) (ENVS = LD_LIBRARY_PATH=/u01/app/oracle/product/8.1 7/ctx/lib) (PROGRAM = extproc) ) ) You can see that the SID_DESC entries layout are slightly different that those earlier, is this OK?

RE: Transferring data from one table to another
