Worked well, after our SA rebuilt the servers from ground 0. Adding it on to an existing server is ok, but somewhat unstable. One item to be VERY careful of. The heartbeat cable, in our case a ethernet thin line, needs to be on a dedicated link, preferably a purchased vs. custom made cable, and protected from accidental disconnect. Ours got disconnected by a contractor working in the computer room because it was in his way. The resulting reboot of the backup server and forcible takeover of the disk farm absolutely destroyed the database. We had more file corruption than I ever could have imagined. Consequently we abandoned ServiceGuard are going to standby databases instead. Dick Goulet Reply Separator Author: Rama Malladi [EMAIL PROTECTED] Date: 2/6/2002 5:23 PM Hi...

Weird connection behavior

Re: Bitmap Indexes
Ethan, We are using all bitmap indexes on our main fact table. We also have a mix of bitmap and b-tree indexes on other tables. The bitmap indexes work best in SQL with multiple where clauses anded together where each column in the where clause has a bit-map index on it. The more of these bit-mapped indexes that you have in your where clause, the better. At least two is best. We have quite a lot of pockets of poor performance. Many of those explain plans mix bit-mapped indexes with b-tree indexes. I've never seen the optimizer try to convert a bit-mapped index to a b-tree index but we are at 8.0.4. I've never tried to convert a bit-mapped index to a b-tree or vice-versa.Might be interesting to try. However it's tough because this is a production database that was already in place when I got here. I should also note that our fact table and several others are partitioned and we have star_transformation_enabled set to true. Please post a summary of your results to the list if you have time. This is an interesting thread. Cherie Machler Oracle DBA Gelco Information Network. Post, Ethan Ethan.Post@ps To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] .netcc: Sent by: Subject: Bitmap Indexes [EMAIL PROTECTED] om 02/07/02 03:06 PM Please respond to ORACLE-L Posted on behalf of a friend... Fellow Oracle data warehouse DBAs (if this isn't you, you can delete this note now): I have a question regarding Oracle's bitmap indexes. We have been DABBLING with bitmap indexes with mixed results here. In many cases, they are great solutions. In some cases, where we have a mix of bitmap and b-tree indexes on the same table, we occasionally get into trouble --- this has to do with the Oracle optimizer deciding, on the fly, to convert a regular b-tree index into a bitmap. It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone whole hog with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not taking all of our medication, as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes or, Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have. -- Please

We drop and recreate many indexes on our large partitioned fact table in our data warehouse nightly. The amount of data in the table increases gradually with time but there aren't huge fluctuations in the amount of data in the partitions from day to day. The problem is that the amount of time that it takes to recreate the indexes varies widely. From 40 minutes to almost three hours. I am inclined to believe that this is a scheduling issue related to the time of the day and the day of the week. I think we may be experiencing competition from other batch jobs from other applications. One application, in particular, is sort of a black box because it is not on Oracle and it belongs to people who reside in a remote site. However, I want to make sure I've considered all of the possibilities. What factors might influence how long it takes to rebuild indexes on existing partitions? If I just did some maintenance to split out some data for a new time period into a new partition, might that make a difference in how long it takes to build the indexes? These indexes are all locally partitioned indexes. Thanks for any insight you can lend. Cherie Machler Oracle DBA Gelco Information

the solution was to drop reinstall the JVM inside Oracle.
The down side is that after dropping the JVM, the instance needs

RE: Bitmap Indexes
Kirti, Just cureous. Normally bitmap indexes ae ae used for low cardinality columns. I am confused when you state - "Just one table uses it(bitmap index), with b-tree indexes for PKry and one other non-unique index" If you mean - you use Bitmap index for the non unique index with b-tree index for PKey I am OK with that. Shaibal From: "Deshpande, Kirti" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> Subject: RE: Bitmap Indexes Date: Thu, 07 Feb 2002 19:58:20 -0800 Ethan, I have been using bitmap and b-tree indexes on the same table in our data mart since 7.3.4. Never had a problem with query performance. Now we have partitioned the tables in 8.1.7.x and most tables that were using bitmaps do not need to use them anymore. Just one table uses it, with b-tree indexes for PKry and one other non-unique index. No problems so far. The only issue we had with bitmap indexes was the way it used up extents, if those were not droppped before the dataloads. The problem still exists with 8.1.7.x. Have not tried with 9i yet.. HTH, - Kirti -Original Message- Sent: Thursday, February 07, 2002 3:07 PM To: Multiple recipients of list ORACLE-L Posted on behalf of a friend... Fellow Oracle data warehouse DBAs (if this isn't you, you can delete this note now): I have a question regarding Oracle's bitmap indexes. We have been DABBLING with bitmap indexes with mixed results here. In many cases, they are great solutions. In some cases, where we have a mix of bitmap and b-tree indexes on the same table, we occasionally get into trouble --- this has to do with the Oracle optimizer deciding, on the fly, to convert a regular b-tree index into a bitmap. It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone "whole hog" with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not "taking all of our medication", as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, "Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes" or, "Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have". -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Post, Ethan INET: [EMAIL PROTECTED] -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Deshpande, Kirti 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).

Let me add to Bambi's wonderful comments. Administering Oracle
Applications can be a daunting task. Like no other canned application you
have ever implemented. Don't count on the product installing correctly
100%. Don't count on just installing it one time and then leaving it alone.
I guarantee that you will be applying thousands of patches once the
installation is complete???. This product needs A LOT of hand holding so
get your boots on and be ready.
There are many people in this and the OAUG forum that can help you. I
would suggest reading the installation and configuration guide cover to

RE: datafile compression
Keith, I've been using PKZip (version 4.00) under Win2k to zip and unzip Oracle export dump files for months without a hitch. In fact, I just now zipped and unzipped a 400MB 8i datafile with no errors. Are you sure there wasn't some other factor that affected the test you did? Do you have the latest version of PKZip?

Re: ORA-01000: maximum open cursors exceeded
It only cost you memory on the server side - there is practically no performance hit. However, running out of open_cursors could be a sign of incorrectly coded applications, that would open and never close a cursor. You therefore need to keep an eye on this - v$open_cursor may be of interest. Thanks, Bjørn. Farnsworth, Dave wrote: We had this error show up the other day.

RE: Where does a DBA go from here?
Rich, The best Oracle training I've ever had by far is playing around with a small test DB on a laptop or PC. Stress it, hurt it, recover it, tune it, etc., etc. When done in conjunction with one of the fine books mentioned by others on this list - even better. I've only had one official Oracle training course - in the spring of 1989. It was 4-1/2 days of RDBMS v5, SQL*Forms and RPT/RPF. Since then I've attended some of the mini courses at IOUG, ODTUG, Open World, etc. - nice little hits of the latest technologies. I studied for my Oracle8 OCP exams by working through Jason Couchman's book and beating up an 8.0.5 DB on my PC - learned a hell of a lot. My on-going study plan for Oracle skills boils down to Beating, Browsing and Books. - Beat up a test database - Browse fine Web sites like Steve Adams' IXORA (and beat up the DB) - Buy and read good books (and beat up the DB) I think I've learned about as much as if I'd sat in a bunch of classes - and saved a pile of money. ;-) Jack Jack C.

Re: MAX_IO_SIZE and Temp Next Extent approach to ORA-03232 Error
When i had this problem i put initial and next extent size of temporary tablespace equal or greater than MAX_IO_SIZE. Example: With MAX_IO_SIZE= 128K the default storage for the initial and next extent must be = (128 * 1024) = 131072 bytes. MAX_IO_SIZE is an Operating system dependant parameter. you can find MAX_IO_SIZE putting db_file_multiblock_read_count = 100 and than trace a full table scan, look in the trace and find the third field in wait: db file scattered read to find number of bd_block read for any I/O operation. Ciao - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Friday, February 08, 2002 1:28 AM Listers, Environment: Solaris 7 running 64 Bit Oracle 8.1.7.2.x. Received an ORA-03232 error this morning after bumping up the HASH_AREA_SIZE on a QA box overnight. HASH_MULTIBLOCK_IO_COUNT is 0, and has been 0 for as long as I know, meaning that Oracle calculates the value on the fly for each individual SQL statement. From information found in Metalink forums, etc, it appears that this has popped up on lots of people after bumping up HASH_AREA_SIZE. Though I couldn't find anything describing *how* Oracle calc's the HASH_MULTIBLOCK_IO_COUNT when set to zero, it appears the HASH_AREA_SIZE plays some role, based on Usenet and MetaLink forum comments. Anyway, to the question. Some of the Oracle notes say that as long as the NEXT extent size for the TEMP tablespace is greater than MAX_IO_SIZE, which is OS dependent (and on Solaris defined by maxphys, I think) the problem should go away. But, some folks posting in the forums say that even if they went with something along the lines of 1 MB for initial and next, with a max_io_size of 128K, they still encountered the error. Anyway, the quick fix was to set HASH_MUTLIBLOCK_IO_COUNT to 2 since this could be done with an ALTER SYSTEM command. But I am curious what other people may have done who have run into with this. We eventually would like to go back to a HASH_MULTIBLOCK_IO_COUNT of 0, if only because Oracle recommends that (good advice?), and address this through appropriate TEMP extent sizing. Heck, you could make the extents pretty large but you would like to know up front if the fix will work. So that's why I ask for feedback here. A TAR will be opened through the point of contact that handles TAR's. We hope to get an official word from Oracle on this. But, the fact that some people have said the extent size bigger than max_io_size didn't work has us wondering. Regards, Larry G.

Fellow Oracle data warehouse DBAs (if this isn't you, you can delete this note now): I have a question regarding Oracle's bitmap indexes. We have been DABBLING with bitmap indexes with mixed results here. In many cases, they are great solutions. In some cases, where we have a mix of bitmap and b-tree indexes on the same table, we occasionally get into trouble --- this has to do with the Oracle optimizer deciding, on the fly, to convert a regular b-tree index into a bitmap. It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone "whole hog" with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not "taking all of our medication", as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, "Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes" or, "Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have". -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Post, Ethan INET: [EMAIL PROTECTED] -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Deshpande, Kirti 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).

It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone "whole hog" with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not "taking all of our medication", as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, "Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes" or, "Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have". -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Post, Ethan INET: [EMAIL PROTECTED] -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Deshpande, Kirti 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: Where does a DBA go from here?
OK, from the responses, here's The Plan: 1) Get beer. I prefer Guinness or Goose Island. Done. 2) Get Oracle Perf Tuning 101. Done. 3) Get more beer. 4) Beat up on some test DBs, and work on real live DBs to engrain that class material into the surviving brain cells (see Step 1). Sorta done with this one, but I need more. The 22 DBs here at work and 1 at home ought to help! 5) Get more beer. 6) Go to Oracle conferences. I need to go 7) Get more beer. 8) Hit the web, preferrably with beer in non-mouse hand. (Wisconsin twin-can beer hat optional) 9) Go to Internals class and actually understand and learn from it. Yay! 10) Get lots more beer. 11) Actually do some work here. Sounds good folks.

We drop and recreate many indexes on our large partitioned fact table in our data warehouse nightly. The amount of data in the table increases gradually with time but there aren't huge fluctuations in the amount of data in the partitions from day to day. The problem is that the amount of time that it takes to recreate the indexes varies widely. From 40 minutes to almost three hours. I am inclined to believe that this is a scheduling issue related to the time of the day and the day of the week. I think we may be experiencing competition from other batch jobs from other applications. One application, in particular, is sort of a black box because it is not on Oracle and it belongs to people who reside in a remote site. However, I want to make sure I've considered all of the possibilities. What factors might influence how long it takes to rebuild indexes on existing partitions? If I just did some maintenance to split out some data for a new time period into a new partition, might that make a difference in how long it takes to build the indexes? These indexes are all locally partitioned indexes. Thanks for any insight you can lend.

Re:RE: MC/Serviceguard vs Sun Clusters
Glenn, The database corruption we had occurred under a very specific circumstance. It occurred only when the prime server was alive well and the backup server thought the prime had died. Now, after some correction by my SA, we were using a much older version of ServiceGuard at the time things have somewhat changed in the interim although not enough to make him comfortable. In this scenario, the backup system rebooted. During that reboot it forcibly wrenched the disk drives away from the prime system, forcing a complete failure of the prime server, then mounted and tried to run the database. When this occurred file lengths would change all over the place, control files would be 0 bytes, a 100 MB datafile might tell you it was 150MB or 50MB. Mount points that had been 40% used were now either 100% or 0% used. In short all kinds of strange things would happen, to Oracle and HP files. HP admitted that this would happen, since the files were 'still opened for write by the prime system' and had been improperly switched. Regrettably at the time they did not have a way to prevent it. Dick Goulet Reply Separator Author: Glenn Travis [EMAIL PROTECTED] Date: 2/7/2002 1:07 PM Could you explain the file corruption in a little more detail?

The heartbeat cable, in our case a ethernet thin line, needs to be on a dedicated link, preferably a purchased vs. custom made cable, and protected from accidental disconnect. Ours got disconnected by a contractor working in the computer room because it was in his way.

Re: Performance issues
You should not expect to see much performance improvement, except in special cases where you can replace large deletes or loads by simpler partition operations. Your decision to use partitioning should be based on the ability to handle (i.e. DBA work) partitions separately, where you can e.g. mass delete/load, make parts read-only to reduce backup, or enable partial recovery during disk outages. Note, however, that much of this depends on your ability to partition indexes and data equivalently so that you avoid global indexes.

Stress it, hurt it, recover it, tune it, etc., etc. When done in conjunction with one of the fine books mentioned by others on this list - even better. I've only had one official Oracle training course - in the spring of 1989. It was 4-1/2 days of RDBMS v5, SQL*Forms and RPT/RPF. Since then I've attended some of the mini courses at IOUG, ODTUG, Open World, etc. - nice little hits of the latest technologies. I studied for my Oracle8 OCP exams by working through Jason Couchman's book and beating up an 8.0.5 DB on my PC - learned a hell of a lot. My on-going study plan for Oracle skills boils down to Beating, Browsing and Books. - Beat up a test database - Browse fine Web sites like Steve Adams' IXORA (and beat up the DB) - Buy and read good books (and beat up the DB) I think I've learned about as much as if I'd sat in a bunch of classes - and saved a pile of money. ;-) Jack Jack C.

We drop and recreate many indexes on our large partitioned fact table in our data warehouse nightly. The amount of data in the table increases gradually with time but there aren't huge fluctuations in the amount of data in the partitions from day to day. The problem is that the amount of time that it takes to recreate the indexes varies widely. From 40 minutes to almost three hours. I am inclined to believe that this is a scheduling issue related to the time of the day and the day of the week. I think we may be experiencing competition from other batch jobs from other applications. One application, in particular, is sort of a black box because it is not on Oracle and it belongs to people who reside in a remote site. However, I want to make sure I've considered all of the possibilities. What factors might influence how long it takes to rebuild indexes on existing partitions? If I just did some maintenance to split out some data for a new time period into a new partition, might that make a difference in how long it takes to build the indexes? These indexes are all locally partitioned indexes. Thanks for any insight you can lend.

RE: TFM
April, We upgraded from 10.7 to 11i. We had to apply around 200 patches. The entire upgrade project took 9 months. I suggest hiring consultants to help with the install. This will consume 100% of you time until it is fully implemented. After that it will consume around 50% of your time, depending on the modules you will be using. If you are the only DBA, start pushing management to hire another person. You will need to tune the concurrent managers, apply patches, clone the entire environment, etc. We have 1 person dedicated to administering the applications portion - creating users, monitoring the concurrent managers, assisting users with problems, applying patches, etc. We have a dba dedicated to backups, tuning, assisting with patches, assisting with client issues, etc. Welcome to hell.

RE: Bitmap Indexes
Kirti, ' The only issue we had with bitmap indexes was the way it used up extents, if those were not droppped before the dataloads.' If I remember correctly, this issue was fixed in 7.3.4.4 as I was having the same problem while dataload in our datawarehouse and workaround was to drop index before inserts and an index size 10M was using unlimited space. This problem was in 7.3.4.0...Besides there were couple of other issues relating to bitmap indexes specially rebuilding of bitmap index on a table which was having degree 1 was resulting in ORA-600 messages even if you were not specifying parallel option. I worked with Oracle Support on this issue for around one year but not resloved till I left that company.

RE: cost based optimizer
First, you should be aware that the Cost is only Oracle's best guess as to what Access Path is faster. It's often wrong. What version are you on? Depending on version you have several options 1. Create a histogram on the XSKSHDRS181M1 column 2. Set the optimizer_index_cost_adj equal to a value under 100. This lowers the cost Oracle assumes an index will add. We have it set to 75 on our data warehouse. 3. Associate the access path resulting with using the hint with the SQL (I don't remember how to do this, but remember reading about it around a year ago). Good luck!

the script will stop running. How do I tell it to continue to check the

RE: cost based optimizer
Title: cost based optimizer
John:
The
Cost of a query is based on Oracle's estimation of the number of datablocks that
will have to be read in order to resolve the query. The Index-access Plan's cost
is higher because Oracle is estimating that it will have to process more
datablocks to return the requested rows.
Oracle's optimizer isn't perfect. I have found that the
Cost of a query is a reasonable measure of relative performance of queries only
when the estimated number of rows(Card=999) is reasonably
accurate.
You
didn't say what version of Oracle you are using. If you are using Oracle 8i or
above, you can use the Plan Stability feature to specify the explain plan for
the query without using hints.

Title: RE: URGENT Help on tracking unauthorized login to Oracle Database I have an idea for a poor man's version of what you are looking for. Turn on listener logging to a level high enough where you can see the text of the net traffic. With some creativity or a copy of Sed Awk you'll be able to search for the invalid username/password text. A visual inspection of the surrounding log file lines will give you machine name, osuser, username, etc. Depending on your connection activity disk space may be an issue.

HTH, - Kirti -Original Message- Sent: Thursday, February 07, 2002 3:07 PM To: Multiple recipients of list ORACLE-L Posted on behalf of a friend... Fellow Oracle data warehouse DBAs (if this isn't you, you can delete this note now): I have a question regarding Oracle's bitmap indexes. We have been DABBLING with bitmap indexes with mixed results here. In many cases, they are great solutions. In some cases, where we have a mix of bitmap and b-tree indexes on the same table, we occasionally get into trouble --- this has to do with the Oracle optimizer deciding, on the fly, to convert a regular b-tree index into a bitmap. It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone "whole hog" with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not "taking all of our medication", as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, "Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes" or, "Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have". -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Post, Ethan INET: [EMAIL PROTECTED] -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Deshpande, Kirti 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: DO YOU HAVE ANY DATABASE RUNNING ACTIVE 1000 SESSIONS ?
Hi Bunyamin, list, We have a system that supports many tens of thousands of simultaneous users. It has 1466 sessions connected as we speak, and generally has around 100 of those sessions marked status "ACTIVE" in v$session. We do concentrate users to sessions in a web layer. We did at one time attempt MTS, however we found that we quickly went down as dispatchers failed to keep up with the load. Oracle did its best to help us tune it, and we tried half a dozen possible configurations, but eventually the attempts were causing too much downtime and we went back to dedicated session. At peak time, our call rate is 25 user calls per minute. Hope this helps, Paul - Original Message - From: Bunyamin K.

HTH, - Kirti -Original Message- Sent: Thursday, February 07, 2002 3:07 PM To: Multiple recipients of list ORACLE-L Posted on behalf of a friend... Fellow Oracle data warehouse DBAs (if this isn't you, you can delete this note now): I have a question regarding Oracle's bitmap indexes. We have been DABBLING with bitmap indexes with mixed results here. In many cases, they are great solutions. In some cases, where we have a mix of bitmap and b-tree indexes on the same table, we occasionally get into trouble --- this has to do with the Oracle optimizer deciding, on the fly, to convert a regular b-tree index into a bitmap. It does this so that it can AND or OR the various bitmap indexes together. Sounds great on the surface but when this occurs, response time goes in the toilet. In one situation we have, we have a fact table with two bitmap indexes and a few other b-tree indexes. A particular query we run bogs down (NEVER COMPLETES) with this mix of indexes. Based on the access path that's being chosen, we know which b-tree index is being converted on the fly. If we convert that b-tree index into a bitmap (so we now have 3 bitmap indexes and Oracle does not need to create the third one on the fly), the query really runs well. If we replace the bitmap indexes with b-tree indexes (so we only have b-tree indexes), we get decent response times. (This is all on Oracle 8.1.7.2.0, by the way.) I'm wondering if the rest of you data warehouse DBAs have gone "whole hog" with bitmap indexes. My testing shows that when Oracle doesn't have to create a bitmap index on the fly, the queries respond wonderfully. So, I'm wondering if our dabbling is actually a bad validation approach and, instead, we should be 'running' with LOTS bitmap indexes instead of 'crawling' with only a few of them. In other words, maybe we're not "taking all of our medication", as someone else put it recently. Any insight would be most appreciated. I'm not looking for insight on the query I have used as an example. I'm looking for a generalized answer that says, "Yes, if you start using bitmap indexes, you should go TOTALLY to bitmap indexes" or, "Hmmm, we're using some bitmap indexes and some b-tree indexes and don't have the problem you have". -- Please see

RE: Migrating from 8.1.6 EE to 8.1.7 SE
Helmut - SE vs.. EE is a matter of features. The aspect you must study is whether you are using any EE features. You don't want to migrate to SE only to find that some important parts of your application rely on EE features. Compared to that, getting the data moved should be a snap. Unless your database is so large you need to migrate it, you may just want to install 8.1.7 SE, then export and import your data to move it. As near as I can tell, Oracle only offers SE because MS SQL has a very appealing cost model (upgrades are extra). Oracle went through its product and removed features that MS doesn't have and called that SE, and priced it much lower. Therefore, I don't think Oracle is eager for you to move from EE to SE, and probably don't offer any special assistance. Dennis Williams DBA Lifetouch, Inc.

RE: Re: Performance issues
To: 'Mohammad Rafiq' [EMAIL PROTECTED] Date: Fri, 8 Feb 2002 15:25:32 -0500 There are two parts to this issue. 1. DBA issue, that Bj0rn Engsig talked about. 2. System performance. We have couple of systems where one of our table has 70 million rows and the other 110 million rows. We just converted our 70 million records table to a partitioned table. Table is spread over 12 drives is using 0+1 RAID. Index is partitioned but is on 4 drives. Reason for doing this was that when 12 processes were trying to insert into the table we were getting buffer busy waits. Most of the processes were trying to write to the same block. Partitioning the table cut down the buffer busy waits. Spreading the table on more drives removed the db sequential read problems. We still had to go further and optimize the SQL to minimize disk reads and so on, but we cut down the I/O wait time. By partitioning the table and index, you are dealing with a piece of the table for access and insert. That means rather than dealing with 100 million rows table, you will be dealing with say 10 million rows table. We used to have a 31 million records table for 31 days data. About 10 years go we split this table into 31 of 1 million rows tables and associated indexes. This way we deal with only 1 million records tables, which were much smaller to manage as well as provided faster access. With partitioning option you are basically doing the same thing, except you have one table but it is broken up in 31 tables. It still has one name but it could be spread of 3 to 30 drives and no one but the DBA knows the difference. So divide and conquer is the strategy. Make it smaller and make it manageable. Reduce I/O contention and increase access time. Table and index Partitioning will help but it is not the only thing. Most important of all is how optimized, well structured and architected code is. This is where we spent most of the time. To modify the code, so we minimize number of SQL executions. Remove SQL from inner loops, optimize the SQL and specially process all the data as it came from the disks, so we do not have to go back to disk to get the data for processing it later. Keep your disk I/O down, buffer_get(reads) low by optimizing the INDEXes. From your email I can not tell what type of application you are working on. If it is data warehouse type application, Oracle has a good article on their site about using bitmap indexes and partitioning that might help you. If you are going to partition tables and indexes, you may want to consider Oracle parallel processing. That means you may need a multi-processor machine. You would consider having multiple controllers, if table spread over many drives. The list can be quite long depending on what your requirements are.

Reply-To: [EMAIL PROTECTED] You should not expect to see much performance improvement, except in special cases where you can replace large deletes or loads by simpler partition operations. Your decision to use partitioning should be based on the ability to handle (i.e. DBA work) partitions separately, where you can e.g. mass delete/load, make parts read-only to reduce backup, or enable partial recovery during disk outages. Note, however, that much of this depends on your ability to partition indexes and data equivalently so that you avoid global indexes.
