RE: seperate external procedure listeners for different SIDs
Dick/John Thanks for all your input. I conclude from this discussion that it is not possible to have different, seperate external procedure listeners for different SIDs in the same instance at least not in 8.1.7. Incidentially, I have been having an issue with running an rsh command via an external procedure. The external procedure is a C .so which uses the C system command to run a Unix command. Sometimes the Unix command is an rsh. What I find is that sometimes the rsh command causes the ORA-28576 lost RPC connection to external procedure agent. However if I make the external procedure listener seperate and start it off as follows from the root crontab or inittab /usr/bin/su - oracle -c /u01/app/oracle/product/8.1.7/bin/lsnrctl start listener_ext Then I never get the error. Just wondered if anyone had any thoughts as to why starting the external procedure listener in this way seems to resolve the ORA-28576 error with rsh commands. John -Original Message- Sent: 08 January 2004 15:59 To: Multiple recipients of list ORACLE-L John, I agree if you have multiple databases under the same home all is well, one extproc sid will do. But if you have several different Oracle homes, with different versions of Oracle then each needs it's own extproc sid. Tried using the latest listener and/or extproc combinations, didn't work. Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -Original Message- Sent: Thursday, January 08, 2004 10:44 AM To: Multiple recipients of list ORACLE-L Thanks - I wasn't sure if each session got its own instance of extproc. The SID associated with an EXTPROC is not the same as a SID associated with a database. I have several databases running under the same Oracle Home, and they are sharing the same external procedure listener - which references that Oracle Home. If you are running databases under several versions of Oracle, you may be able to use the listener for the latest version of Oracle you have to listen for all of them, and use its extproc. But it is probably a better idea to run separate listeners for databases and external procedures, each with its own LISTENER.ORA and TNSNAMES.ORA under its own Oracle Home. Just be careful about how the TNS administration directory is set. -Original Message- Sent: Thursday, January 08, 2004 9:54 AM To: Multiple recipients of list ORACLE-L John, On the contrary. You do need to associate an EXTPROC with a particular SID otherwise running different versions of Oracle on the same box blows the EXTPROC to hell. You'll notice that in listener.ora there needs to be a line SID_NAME= and in TNSNAMES.ora there is a Connect_data = (sid = as well. Now a particular database instance/version can only have one extproc_connect_data entry, but with multiple versions each has it's own, and sure enough each has to have a particular sid otherwise they mess each other up. BTW: Your description of the process is dead on, with one exception. An instance of extproc is connected to one and only one session in the calling database. If two sessions each need to call an external procedure then each gets it's own instance of extproc. Also if you need to update the dll or so file you have to get everyone to let go of extproc, namely by disconnecting from the database. Although it's like a database link, closing the links does not release extproc. Also using TCP to connect to extproc is not an Oracle recommended method, opens a door to hackers.

Re: table reorganizations
Richard, I agree there are a number of reasons for reorganising tables. LMTs remove the need to reorganise a tablespace but not to reorganise a table. Two further real- ilfe examples of table reorgs: 1) The purge programs have at last been written and run deleting data 2 years old. The system's been running for 4 years. So in simple terms most of the tables are approx 50% empty. You need to reorg in this case. 2) A transaction log table is inserted to throughout the day and most of the night. A clear down processing job runs at the end of the day and deletes all the rows its processed, but more rows are being added. So the table is now 1% full. Not good for FTS. So instead of a conventional reorg we implemented a nightly table-swap. This meant locking the source table, copying it's contents to a replica empty single extent table, target table. The names of the target and source tables are swapped, hence table-swap. The new source table is now available to the application and the original source is truncated and ready to be the target in 24 hrs time.

RE: table reorganizations
Chris, I would argue that in your two examples, nothing needs to be done if you are using Locally Managed Tablespaces. All of the free space that your deletes generated would be reused by new inserts. When you say not good for FTS, I think you are wrong. Have you tried testing this statement? How much slower is it? Of course, I am talking about using Oracle 9i. Prior versions behaved much differently.

Re: Should we stop analyzing?
- Original Message - Wouldn't it be nice if dbms_stats could do an incremental refresh, tracking ONLY stats changes that might make a difference to execution plan: I'd settle for a flag I could turn on and off, saying: do/do not change stats for this object. I know which of them need to be analyzed and which don't. Better than Oracle will ever, deltas or no deltas, workload managers or not. a) Allow for dbms_stats to collect, store and compare changes to historical execution plans, using historical SQL from STATSPACK (or new 10g workload views) Sadly, this workload feature of 10g if I know anything about how Oracle works, will evolve into another monster elephant gun. Completely forgetting the problem out there is in most cases mosquito-size and can be addressed with a simple fly-swat. Yes, there is such a thing as over-engineering a solution. This will be one of them. And like anything that is over-engineered, it will be buggy - sorry Pete, feature-reluctant. Or perheaps document-challenged? And it will create a bad name for itself while the developers evolve it until Oracle 12r2... b) Allow the DBA control about whether to implement the new statistics That, sadly, is totally outside of Oracle's plans for the traditional production DBA role in future. It would cost these clients many thousands of dollars to have adjusted these plans, and management says If it ain't broke, why fix it. My problem too. Try and convince a damager that something that is working fine should have thousands of buckeroos spent on it to become compatible with new CBO! Like Heck it's gonna happen... Cripes, I know quite a few sites here that are STILL running Prime computers with Prime Information (for those who don't know, look-up Pick in google), 13 years after the company vanished! And no plans whatsoever to update. Why? Heck, it WORKS! Talk about TCO, eh? Oracle made a big-deal about going to the CBO in 11i, yet when we look at the SQL, a significant number of statement employ the rule hint!

Export bigger then 2G with Oracle7.3.4

Export / Import Question
I have a user who want to refresh only the DATA in a test database with DATA from the production database. He does not want to replace any procedures, functions, triggers, etc... My question is, if I do a full or user level export, then turn around and do a full or user level import with IGNORE=Y (after truncating the tables) will the procedures, functions, triggers be replaced anyway? I have a feeling they will. If so, is there any way to prevent this? Thanks! R Smith -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Smith, Ron L.

Re: Export bigger then 2G with Oracle7.3.4
Is any single table more than 2G ? If not, just break up the export into individual schemas and/or tables. For those tables that are more than 2G, you could compress via a pipe - for NT might mean running export over sqlnet from a unix box. hth connor --- [EMAIL PROTECTED] wrote: Hi DBAs, Because of some requirements from one of our vendor, we still have a database running Oracle7.3.4 on WindowsNT and since this package is no longer used, so we want to export the content of this database.

Re: table reorganizations

Because of some requirements from one of our vendor, we still have a
database running Oracle7.3.4 on WindowsNT and since this package is no
longer used, so we want to export the content of this database. The
database is around 60G, one table is 55G. So a simple export on release
7 will crash when I will get 2G of dump file.
The export utility for release 7 doesn't allow us to create multiple
files, but the export utility for release 8 does. I know that they
recommend to always use the lower version of export, but is there a way
to use export 8i and create multiple files on a Oracle7.3.4 database?
If not, what can I do?

RE: Oracle Standby.
There are good documents on Metalink (one in particular by Lawrence To). The Oracle RDBMS manuals are informative as well. I run a script bat file on Windows on the primary to transfer the logs every half hour to the secondary. And a bat file once a day on the secondary to apply the logs. I use blat to send an email of the last log applied so that I can be sure everything is OK. I don't run in managed mode, the servers come down occasionally and that messes up the standby if you're not careful.

You don't mention OS, but if it's a flavor of unix, you could probably do: mknod my_pipe p exp file=my_pipe all other export options split -b 2047m my_pipe exp.dmp This will generate multiple files, 2.047 MB per file.

RE: Suggestions Needed: Latch free - library cache
During the Hotsos course I thought I remember hearing that the pool could be too large and that could have a negative impact on the library cache latch. Am I confusing this with something else (maybe the buffer busy event)? If true how do you go about determining the optimal size? From:Cary Millsap [EMAIL PROTECTED]@fatcity.com on 01/07/2004 07:44 PM PST Please respond to [EMAIL PROTECTED] Sent by:[EMAIL PROTECTED] To:Multiple recipients of list ORACLE-L [EMAIL PROTECTED] cc: Subject:RE: Suggestions Needed: Latch free - library cache One way is by writing applications that use persistent connections. A mid-tier program ignites at 8amJan 1, connects to the Oracle instance, and then parses all the SQL it will use for the remainder of the year. The interface to this program from the user side is via "services," like "hire an employee," "fire an employee," "look up a salary," or whatever. Thousands of users throughout the year use the services, but the only parse calls the application makes all year occurred during the first few minutes of the morning on New Year's Day. Advantages are huge if you eliminate what would otherwise have been thousands of connections/disconnections and parse calls per day. All the db gets are binds, executes, and fetches except for the first few minutes after instance start-up.

RE: Export / Import Question
Ron, I share your feeling. All stored objects are recreated with CREATE OR REPLACE - IGNORE=Y is inoperant for them. IMHO the best you can do is generate as many table-level exports as you have tables, with TRIGGERS=N. Of course, usual fun with constraints. On the bright side, you will be able to parallelize like crazy. At this stage, dumping to a flat file and using sqlldr might be an even better option than imp/exp.

RE: rman restore question
Joan - Glad to hear your success. In the meanwhile I replied to your earlier message. Just to clarify, when you used a time-based recovery, setting a time earlier than the most recent backup, RMAN ignored the most recent backup and restored from an earlier backup? Wouldn't that have the disadvantage that you're stuck with a database that doesn't have all the recent transactions applied? Just asking, you're probably suffering from recovery fatigue now.

RE: rman restore question
Joan - I have not used the redundancy policy, but my understanding is this just involves how many backup copies to retain. It does not relate to recovery as I read the manual. Do you have Robert Freeman's book Oracle9i RMAN Backup Recovery? Are you attempting an incomplete recovery or a complete recovery? Any recovery to a time prior to the current time is defined as an incomplete recovery. If I am recalling your goal, you are trying to recover but not use the latest backup sets. I always back up using an RMAN catalog, but have always tested recovery just using the control file. On Oracle8i I found it easier to separately issue a SQL command to back up the control file after an RMAN backup, then I ensure that control file ends up on the backup tape. This means that I can take the backup tape, restore the control file, then issue RMAN commands that will restore the database. That control file only knows about the RMAN backup that was last performed. So I could restore the data files from any backup. Now, as you know, recovery in RMAN is basically a shell over the Oracle recovery mechanism. You can restore using RMAN, then recover the database using Oracle server manager (now SQL*Plus) commands. So it should be possible to restore the database using RMAN as I described it (but not restore), then replace the old control file with a more recent control file, then recover the database (Oracle will apply archive log files) until the current time is reached. Obviously by starting with an older restore, more archive logs must be applied. Take a look at this idea and see if it would meet your requirements. Dennis Williams DBA Lifetouch, Inc.

RE: Suggestions Needed: Latch free - library cache
Title: Message Tracy, That's true, though it's less true in 8i and later than it was in 8.0 and earlier. This is due to the way that Oracle organizes free memory chunks. As to determining optimal size, well, if you run into ORA-4031 errors, then, short of a very poorly written application (that does lots of literal SQL), or a bug in your version of Oracle, the shared pool is probably too small. If you have lots of spare free memory after the system has been up and stable for a while, then your shared pool is probably too large. Steve Adams has the shared_pool_spare_free.sql script on his website, http://www.ixora.com.au/. Hope that helps, -Mark Mark J.

A mid-tier program ignites at 8amJan 1, connects to the Oracle instance, and then parses all the SQL it will use for the remainder of the year. The interface to this program from the user side is via "services," like "hire an employee," "fire an employee," "look up a salary," or whatever. Thousands of users throughout the year use the services, but the only parse calls the application makes all year occurred during the first few minutes of the morning on New Year's Day.

Re: Re: table reorganizations
Another way would be to do exchange partition between a single- or multipartition partitioned table and a regular table.

So in simple terms most of the tables are approx 50% empty. You need to reorg in this case. 2) A transaction log table is inserted to throughout the day and most of the night. A clear down processing job runs at the end of the day and deletes all the rows its processed, but more rows are being added. So the table is now 1% full. Not good for FTS. So instead of a conventional reorg we implemented a nightly table-swap. This meant locking the source table, copying it's contents to a replica empty single extent table, target table. The names of the target and source tables are swapped, hence table-swap.

RE: seperate external procedure listeners for different SIDs
HUMM, I've taken a pretty tight stand against open ended external procedures and Java Stored Procedures. Thankfully the developers here agree. Basically I've told them that can't have an external or java procedure that executes a command send into it. That being the case rsh or sh command processors are verboten. Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -Original Message- Sent: Friday, January 09, 2004 5:29 AM To: Multiple recipients of list ORACLE-L Dick/John Thanks for all your input. I conclude from this discussion that it is not possible to have different, seperate external procedure listeners for different SIDs in the same instance at least not in 8.1.7. Incidentially, I have been having an issue with running an rsh command via an external procedure. The external procedure is a C .so which uses the C system command to run a Unix command. Sometimes the Unix command is an rsh. What I find is that sometimes the rsh command causes the ORA-28576 lost RPC connection to external procedure agent. However if I make the external procedure listener seperate and start it off as follows from the root crontab or inittab /usr/bin/su - oracle -c /u01/app/oracle/product/8.1.7/bin/lsnrctl start listener_ext Then I never get the error. Just wondered if anyone had any thoughts as to why starting the external procedure listener in this way seems to resolve the ORA-28576 error with rsh commands. John -Original Message- Sent: 08 January 2004 15:59 To: Multiple recipients of list ORACLE-L John, I agree if you have multiple databases under the same home all is well, one extproc sid will do. But if you have several different Oracle homes, with different versions of Oracle then each needs it's own extproc sid. Tried using the latest listener and/or extproc combinations, didn't work. Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -Original Message- Sent: Thursday, January 08, 2004 10:44 AM To: Multiple recipients of list ORACLE-L Thanks - I wasn't sure if each session got its own instance of extproc. The SID associated with an EXTPROC is not the same as a SID associated with a database. I have several databases running under the same Oracle Home, and they are sharing the same external procedure listener - which references that Oracle Home. If you are running databases under several versions of Oracle, you may be able to use the listener for the latest version of Oracle you have to listen for all of them, and use its extproc. But it is probably a better idea to run separate listeners for databases and external procedures, each with its own LISTENER.ORA and TNSNAMES.ORA under its own Oracle Home. Just be careful about how the TNS administration directory is set. -Original Message- Sent: Thursday, January 08, 2004 9:54 AM To: Multiple recipients of list ORACLE-L John, On the contrary. You do need to associate an EXTPROC with a particular SID otherwise running different versions of Oracle on the same box blows the EXTPROC to hell. You'll notice that in listener.ora there needs to be a line SID_NAME= and in TNSNAMES.ora there is a Connect_data = (sid = as well. Now a particular database instance/version can only have one extproc_connect_data entry, but with multiple versions each has it's own, and sure enough each has to have a particular sid otherwise they mess each other up. BTW: Your description of the process is dead on, with one exception. An instance of extproc is connected to one and only one session in the calling database. If two sessions each need to call an external procedure then each gets it's own instance of extproc. Also if you need to update the dll or so file you have to get everyone to let go of extproc, namely by disconnecting from the database. Although it's like a database link, closing the links does not release extproc. Also using TCP to connect to extproc is not an Oracle recommended method, opens a door to hackers.

Re: Suggestions Needed: Latch free - library cache
To the OP: Other people point out common reasons for library cache latch contention. A less common reason is extensive use of public synonyms. If that's the reason, you also see row cache objects latch contention. I'm not sure that's right. If everyone uses a public synonym, then you get one sql text, and one cursor. I think the contention appears because everyone has to have a 'non-existent' reference in memory to say that they don't own an object with the same name as the public synonym - consequently if you have lots of users who have to check long chains of 'non-existent' then the latches get held for longer periods of time. Hi Jonathan, I don't see how your statement contradicts the claim that heavy use of public synonyms causes contention for not only library cache latches but also row cache objects latches. What I had in mind is Steve Adams' test. Here's the URL http://www.ixora.com.au/newsletter/2001_05.htm#synonyms. If I understand right, the additional row cache objects latch gets are for synonym translations, particularly public synonym translations. Yong Huang __ Do you Yahoo!? Yahoo!

Re: seperate external procedure listeners for different SIDs
This is the only reasonable policy, because all OS commands would necessarily execute on the server side. Developers, generally speaking, do not have access to the database server, so I don't see much use for that. If the idea is to spawn a command on the developer's workstation by using rsh or remsh (HP-UX), then it would require a great multitude of .rhosts files, which would render the whole network insecure. I did, however, see a reasonable application of external procedures. Database server was on the same machine as a scanner. External procedure made it possible for the operator to scan a form, OCR it, and store it as BFILE, all from Oracle*Forms on a client. Essentially, external procedure controlled the scanner and invoked OCR. Both scanner and PC were out of the computer room, so operator did not need access to the sensitive facilities.

John -Original Message- Sent: 08 January 2004 15:59 To: Multiple recipients of list ORACLE-L John, I agree if you have multiple databases under the same home all is well, one extproc sid will do. But if you have several different Oracle homes, with different versions of Oracle then each needs it's own extproc sid. Tried using the latest listener and/or extproc combinations, didn't work. Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -Original Message- Sent: Thursday, January 08, 2004 10:44 AM To: Multiple recipients of list ORACLE-L Thanks - I wasn't sure if each session got its own instance of extproc. The SID associated with an EXTPROC is not the same as a SID associated with a database. I have several databases running under the same Oracle Home, and they are sharing the same external procedure listener - which references that Oracle Home. If you are running databases under several versions of Oracle, you may be able to use the listener for the latest version of Oracle you have to listen for all of them, and use its extproc. But it is probably a better idea to run separate listeners for databases and external procedures, each with its own LISTENER.ORA and TNSNAMES.ORA under its own Oracle Home. Just be careful about how the TNS administration directory is set. -Original Message- Sent: Thursday, January 08, 2004 9:54 AM To: Multiple recipients of list ORACLE-L John, On the contrary. You do need to associate an EXTPROC with a particular SID otherwise running different versions of Oracle on the same box blows the EXTPROC to hell. You'll notice that in listener.ora there needs to be a line SID_NAME= and in TNSNAMES.ora there is a Connect_data = (sid = as well. Now a particular database instance/version can only have one extproc_connect_data entry, but with multiple versions each has it's own, and sure enough each has to have a particular sid otherwise they mess each other up. BTW: Your description of the process is dead on, with one exception. An instance of extproc is connected to one and only one session in the calling database. If two sessions each need to call an external procedure then each gets it's own instance of extproc. Also if you need to update the dll or so file you have to get everyone to let go of extproc, namely by disconnecting from the database. Although it's like a database link, closing the links does not release extproc. Also using TCP to connect to extproc is not an Oracle recommended method, opens a door
RE: Suggestions Needed: Latch free - library cache
During the Hotsos course I thought I remember hearing that the pool could be too large and that could have a negative impact on the library cache latch. Â Am I confusing this with something else (maybe the buffer busy event)? Â If true how do you go about determining the optimal size? Â Having too large shared pool may cause contention on shared pool latch, especially when shared pool's LRU lists get very long, causing searching for unpinned recreatable chunks to take long time (using CPU and preventing others from scanning the list). Before 9i there was only one shared pool latch protecting operations on whole shared pool. But starting from 9i, this issue can be relieved somewhat, but splitting the shared pool heap to several smaller heaps and assigning one shared pool child latch for each of them. This can be controlled using _kghdsidx_count parameter and the max in 9.2 seems to be 7, since there are 7 shared pool child latches (at least on W2K and Linux). However, when you split your shared pool to several parts, you might hit ORA-4031 error even when some shared pool heaps do have enough usable space, but the current one where allocation was tried, doesn't. Tanel. Tanel.

A less common reason is extensive use of public synonyms. If that's the reason, you also see row cache objects latch contention. I'm not sure that's right. If everyone uses a public synonym, then you get one sql text, and one cursor. I think the contention appears because everyone has to have a 'non-existent' reference in memory to say that they don't own an object with the same name as the public synonym - consequently if you have lots of users who have to check long chains of 'non-existent' then the latches get held for longer periods of time.

As it circumvents the existing firewall, it could get you fired for violating the site security policy, so it isn't necessarily a good solution. But its one worth considering. I really like using dedicated point to point connections between app server and database server where both servers have dual integrated gigabit cards, no one has coughed up the funds for switched gigabit ethernet ports and one of the integrated gigabit nics is unused (for a fat client/server app). but it does not scale for several hosts.

Re: Suggestions Needed: Latch free - library cache
Yong: I have not followed the thread completely. So I may be missing something obvious ;) BEGIN-NON TECHNICAL Many applications (for example Oracle Applications) use public synonyms heavily and running with better (or acceptable) performance. We should not really worry about the milli second performance improvements comparing with the coding/application development flexibilities offered by public synonymns. If you look at Steve's test carefully, the improvement or over head in the public synonym to private synonym is around 10% of the CPU time and latch gets. How much performance improvement you can expect in practical systems with the additiona 10% of latch gets/CPU times comparing with the overall system performance. I would expect less than (LESS THAN) 1-2% in total response time. END NON TECHNICAL The actual over head is coming from the negative dependency tracking or high version count in the Library cache. But this will be an issue only when too many users are connected and accssing the database with too many accounts (different parsing user_id). But this is rarely a situation in many of the packaged application as most of the application connects to the database using a single account (like 'APPS' user in Oracle eBusiness suite) and no negative dependency or multi version of SQLs are an issue here (at least in a single instance oracle). The over head can be little higher in RAC environment as the Library Cache and Row cache is globally co-ordinated. However I have not really seen major problem (may be I have not observed them too keen) with the public synonyms as most of the packaged applications I have worked are using a single oracle account to connect to the database. It is just my personal observation, and may be Jonathan can have a different opinion.

DB_WRITER_PROCESSES vs DBWR_IO_SLAVES
Title: DB_WRITER_PROCESSES vs DBWR_IO_SLAVES Running 9.2.0.2 on AIX 4.3.3. We recently experienced a situation where a datawarehouse database crashed due to a bug dealing with DBWR_IO_SLAVES 0. Oracle's recommended fix was to set the DBWR_IO_SLAVES to 0, which I did. Now, my understanding is that if AIO is enabled on the box, the rule of thumb appears to be to use DB_WRITER_PROCESSES and set DBWR_IO_SLAVES = 0. Now, the Sr DBA here is screaming about the performance since I made the change, in particular, he says he's seeing high redo latch contention and redo log buffer waits which he says validates his contention that we need to get back to using DBWR_IO_SLAVES. I admit I'm confused. I don't clearly see the relationship that he complaining about. My idea of 'monitoring' was to assess free buffer waits, and to monitor the batch schedules to see if any degradation in timing had occurred, and since the change, neither has been an issue. Am I missing something? What stats should I be assessing to contrast the use of DB_WRITER_PROCESSES vs DBWR_IO_SLAVES? And yes, I've googled and metalinked and and most information is mainly pertinent to 7.3.4 and 8i and of a more general nature. And yes, DISK_ASCYCH_IO is set to TRUE. Thanks.

RE: internet secure solutions
Is all SQL*Net traffic between the app server and the database server? In other words, is all traffic secure where packets cannot be sniffed? Or do you need to encrypt the SQL query result set data going from the server to an unknown client? I believe that's what Oracle Advanced Security gives you. If you just want to limit access to the database server and you're using tcp you can put the following entries into the $ORACLE_HOME/network/admin/sqlnet.ora file: TCP.VALIDNODE_CHECKING=yes TCP.INVITED_NODES=(myappserver.mycompany.com,mydbaworkstation.mycompay.c om) Regardless of Oracle implementation, isn't a firewall a mandatory part of the equasion?

RE: Suggestions Needed: Latch free - library cache
Hi Rachel My understanding of the negative aspects of public synonyms is that they kick in as the number of distinct Oracle Users you have increases. My *experience* is much the same as yours - namely I almost couldn't care, however this is predicated on applications tracking users and not using a different Oracle account for each user. (typically we have 1-2 accounts per app). The archetype of application development on Oracle says that you have a different oracle account for each user (albeit probably OS authenticated). Mind you that same archetype says you can change the sql. I think that the drawbacks that steve has in mind don't apply to the majority of 3rd party apps.

RE: table reorganizations
Hi Chris Richard, I agree there are a number of reasons for reorganising tables. LMTs remove the need to reorganise a tablespace but not to reorganise a table. Two further real- ilfe examples of table reorgs: 1) The purge programs have at last been written and run deleting data 2 years old. The system's been running for 4 years. So in simple terms most of the tables are approx 50% empty. You need to reorg in this case. What would be the rationale for this? If the rationale is performance how much faster does it make everything, and how many users are complaining to start with? If purely for space management purposes then I'd ask why the deleted space could not be reused? 2) A transaction log table is inserted to throughout the day and most of the night. A clear down processing job runs at the end of the day and deletes all the rows its processed, but more rows are being added. So the table is now 1% full. Not good for FTS. So instead of a conventional reorg we implemented a nightly table-swap. This meant locking the source table, copying it's contents to a replica empty single extent table, target table. The names of the target and source tables are swapped, hence table-swap. The new source table is now available to the application and the original source is truncated and ready to be the target in 24 hrs time. Pah. Once a day indeed. Once every 5 minutes... I'm interested in why you implemented table swap instead of 'alter table move' which is what we did.

Re: DB_WRITER_PROCESSES vs DBWR_IO_SLAVES
One interpretation of increased red latch contention and log buffer space waits is that more work is being done more quickly - so the log writer can't keep up. This could mean: a)the log writer has slowed down b)the database writer(s) have speeded up, so there is less time lost on write complete waits, free space waits, and (side effect) buffer busy waits. So the symptoms could be positive or negative, and we don't have enough relevant information to say which. Depending on the nature of the application, and the number and duration of sync waits, you could address the log buffer space waits by increasing the size of the log buffer. Are the redo latch waits allocation latch or copy latch ?

RE: Books on rac
I've read a couple of the books available on RAC: - Oracle9i RAC by Madhu Tumma and Mike Ault is decent, I'd give it a 2.5 out of 5. Good multi-platform coverage and decent coverage of the internals. The book suffers from poor layout/editing. The graphics look like they're photocopied and the text material seems a bit unstructured and is poorly indexed. The tuning chapter is also weak. - Oracle Real Application Clusters by Murali Vallath has a lot of generic Oracle DBA material and can might appear as an Oracle overview with RAC chapters added. I sent my copy back to Amazon. For some reason a this title have gotten a lot of good reviews on Amazon. I've by far found Metalink the best source for RAC documentation.

RE: RAC setup on linux
Joe, In random order, here's some hints: Make sure you visit Werner's site, http://www.puschitz.com He has all sorts of non-RAC ideas on how to install Oracle on all sorts of RH flavors. Beware that RH AS 2.1 is bloody old. You may have problems with it recognizing your newer hardware. Since this was just a test for us on a pair of 2.4Ghz P-IVs, I said Screw it! and went with RH9, which config'd our Intel D845 MB, the built-in video, and the built-in 100baseT Ethernet (our older 3com 100baseT PCI card for the private network was recognized OK). Something I have not seen anywhere else (perhaps it's just my lack of understand of a proper network setup), but when you are creating the /etc/hosts file, do NOT alias ANY nodenames to localhost! The Cluster Manager will fail. For example, alias localhost to 127.0.0.1 and NOT to 192.168.1.1 (or whatever your public/domain IP address is). If you need to change kernel settings permanently, instead of echoing values to a pseudo-file in /proc on boot, make the change in /etc/sysctl.conf If you want to try OCFS, you *must* follow Wim's guide on OTN (can't remember the URL, but it was an OracleWorld presentation!). Without following that, 1.08 and 1.09 are deathly slow to the point of unusability. Also beware that OCFS won't work out-of-the box with RH9. I patched 1.08, following guidelines that IBM used to patch XFS for RH9. If you want the patched source, let me know. The rest of my notes seem to mostly relate to that MetaLink doc. If you have problems, post here! There's enough of us that have tried it, that I'm sure you'll get an answer faster than Oracle Support. :) HTH! GL!

RE: Who said Oracle ran better on Win03?
My reading of that is that they chose RH over *Unix* rather than Windows for the DB Server. Detailing the problems encountered while using Windows Server 2003 on the communication and transaction server side, Sharma said, We have been facing this perennial problem of business logic malfunction, which is solved only when we reset the server. We have an active-passive server combination, and hence shifting loads is possible without compromising network availability. Since Forbes' DBA's were already conversant with Unix, shifting to the Linux platform on the database side was not a problem. I also find it interesting that they consider the familiarity of the admins with Unix a plus for the database, but apparently no such concern exists over a much larger switch for the other servers in the system. I'm also a bit surprised given that the problem was with business logic malfunction that they were able to port all their app code to a different platform without recoding (otherwise its comparing apples to oranges).

RE: Suggestions Needed: Latch free - library cache
Um, roles, privileges, etc are administered however you'd like. The only suggestion I'm making is that rather than having public synonyms for all objects in your app_owner schema, each user which needs default access to the objects in the app_owner schema, gets access to that schema via the logon trigger that sets current_schema. This does (should) not have any effect on how you manage roles and permissions, just how Oracle does default object resolution. -Mark Mark J.

The trigger would give everyone the right to do anything the owner could to a table. There are times when I want create a read-only account in addition to an app user. we do allow sqlplus access to production by developers -- in a read-only state so they can investigate end user complaints. --- Bobak, Mark [EMAIL PROTECTED] wrote: The other option is a user logon trigger that does execute immediate 'alter session set current_schema=appowner'; Mark J.

Well, any solution will require consideration of the application design and implementation. I'm just offering a possible suggestion. ;-) Mark J.

If everyone uses a public synonym, then you get one sql text, and one cursor. I think the contention appears because everyone has to have a 'non-existent' reference in memory to say that they don't own an object with the same name as the public synonym - consequently if you have lots of users who have to check long chains of 'non-existent' then the latches get held for longer periods of time. Hi Jonathan, I don't see how your statement contradicts the claim that heavy use of public
