RE: CPU WAIT I/O statistic
Pablo What does your I/O look like while %wio is high? Specifically, I would suggest: - Look at the disk subsystem I/O, is it experiencing a high rate of I/O? - Run STATSPACK and see which tablespaces are hot. - Are a lot of table scans being executed?

What I'm trying to say is that that can't consume CPU cicles if they are waiting (SLEEPING). Why does sar shows that these CPU cicles are used in waiting for I/O? Who's using them? TIA Pablo - I posted the following paragraph yesterday: 3) I looked in Oracle Performance Tuning 101 to see what Gaja has to say. He points out that the Solaris sar -q command has a %wio column, a measure of processes that are currently using the CPU, but are waiting for I/O requests to be serviced and hence are not making prudent use of the CPU. He further says that %sys and %wio should be less than 10-15% and if it is consistently higher you need to get to the bottom of it, and usually it is a application causing the problem.

Does it represent the % of CPU used by the kernel processes to perform I/O? As far as I know the waiting processes do no wait actively when they ask for an I/O. right?

RE: CodeNotes for Oracle9i...
I have an odd question about these on-line books. Can I copy-and-paste the text? Like many of you, I seem to end up with long commutes (why are the best jobs never in your neighborhood?). I find listening to books on CD to be a better use of time than reading bumper stickers. Nobody ever seems to issue Oracle books on audio. So I got a text-to-voice program, and it works pretty good to create an audio version of a book. But many of these eBooks zealously protect their text and prevent you from doing copy-and-paste on the text. Fortunately Oracle makes their books readily available. Any ideas are welcome.

RE: CodeNotes for Oracle9i...OT
It still seems to be restrictive and pricey to me. The 30 books-a-month at a one time yearly fee is $300. At the end of the year, what do you have? Another $300 bill for the next year. And how many books do you have access too, if you don't dish out another $300, ZERO. With bookpool.com, for $300 I can buy quite a few books, that I will still have after one year. Granted after 3 or 4 years those books will be retired, but they definitely paid for themselves. And if my site is slow to upgrade then I may keep my books for even longer...some sites are still running Oracle7. Additionally, paper books are great since you can highlight, mark, scribble notes, attach tabs to the page, etc. Obviously, if I work for a company that has deep pockets then they can pay the bill, but that doesn't appear to be the case today. I love Oreilly books, I just don't like the Safari Bookshelf website deal. This business model needs more work...perhaps they have snagged 9,999 customers, but if they dropped the prices and dropped the restrictions then they will get 999,999,999,999,999 customers.

[EMAIL PROTECTED] 10/11/02 09:48AM
Hello Listers,
I was asked by a co-worker if there was a way in Oracle to prevent
users from connecting to the databases if the same OSUSER has already a
created a specified number of sessions to a particular instance.
We discussed profiles and resource limits etc. However, the requirement
is that the user should a get message that they have exceeded their
quota and should not be allowed to log in (there goes the log on
trigger).
The denial of connection *must* be based on 'OSUSER'. In this
environment different OSUSERs use the same Oracle Username for these
connections, and the expectation is that the DBA find a solution to
enforce some rules.
Any tricks? Third party software?
Thanks.

Particularly in the case where this sequence will see any sort of concurrency, from multiple concurrent sessions accessing it. This is due to the serialization on the SQ enqueue. This will cause far worse scalability issues than any I/O. Not that I/O is insignificant, but in this situation, serialization on the enqueue will be the real showstopper for scalability. As to losing the cached values, well, so what? If your design is such that it's important to have an unbroken contiguous sequence of numbers with no gaps, then I would argue that is a serious design flaw. Also, if that's your requirement, then a sequence is not appropriate, since it can and will end up causing gaps, the first time you roll back a transaction.

RE: Advice needed on move to Sun 15K (losing spindles)
I obviously left out a lot of information :). We would be using server partitioning, with seperate ORACLE_HOMES for each database (necessary since we have a variety of versions running). The box would be running 1+0, the Sun reps suggest striping across all disks (my first red flag). I hadn't even thought of the problem of not being able to reboot the server, that's an excellent point. Currently we have absolutely no performance problems on our OLTP database. This whole kerfuffle was an outgrowth of my pushing really hard to get a backup box for our datawarehouse (which currently has no standby, no box that it can restored to and no QA box). The suggestion was made that rather than get a separate box for the datawarehouse - get the 15K and have the OLTP and datawarehouse on different partitions. This would certainly speed up the data transfer between them (data is transferred from OLTP - Data Warehouse on a daily basis). We could then put other databases that access my databases on other partitions (several other databases have snapshots on some of my tables). So this would make some processes more efficient, but i/o on my OLTP database is currently tuned so well that it hurts every time I think of giving it up. One spindle has the Oracle executables with the redo logs on the outside of the disk. Another has the various .dat files, shell scripts, etc, with the archive logs on the outside of the disk. Even when we run really intensive updates our wio rarely gets very high. Regarding the load question: We have fairly active transaction activity during the day but most connections are managed by Microsoft Transaction Server in a middle tier so while there are usually app. 200 sessions (including some old client server apps) we rarely have more than 20 or so active at any one time. The datawarehouse has fewer sessions but often has some resource intensive queries running. If anyone can point me to docs/websites saying that a large caches does *not* make up for fewer disks/spindles I would greatly appreciate it. Currently I'm being told that Sun must know what they're talking about.

What about the admin issues? If consolidate to a single server, consider a separate ORACLE_HOME for each database. You may need to apply different patches to fix different problems in various databases. You have this ability now, but will lose it if you consolidate without separate ORACLE_HOME's. Something else you will lose is the ability to reboot the server if needed for a single database. Since you may be moving to a 15k, investigate server partitioning to retain this functionality.

The vendor (Sun) was recommending striping across all 4 spindles. He said we don't need to worry about i/o issues because there will be a large cache. I'm skeptical and argued for cutting them in half (striping 2 and 2). We could then at least seperate the redo logs from the datafiles (probably putting them with the oracle executables and some other files). The Sun rep kept talking up how much more powerful the CPUs were and I kept saying, but we're not CPU bound, we don't need any more CPU. If anyone can either a) tell me I'm worrying for nothing b) recommend a better way to stripe/distribute my files c) provide references or experience to show this is a bad idea I'd really appreciate it.

RE: Controlling Users Logons
Ramon,
Thanks a lot.
My problem in using logon trigger turned out to be the 8.1.7.2 version of
the database. Raising appl error is just dumping a trace file without
killing the session. It does work fine with 8.1.7.4 databases.

Particularly in the case where this sequence will see any sort of concurrency, from multiple concurrent sessions accessing it. This is due to the serialization on the SQ enqueue. This will cause far worse scalability issues than any I/O. Not that I/O is insignificant, but in this situation, serialization on the enqueue will be the real showstopper for scalability. As to losing the cached values, well, so what? If your design is such that it's important to have an unbroken contiguous sequence of numbers with no gaps, then I would argue that is a serious design flaw. Also, if that's your requirement, then a sequence is not appropriate, since it can and will end up causing gaps, the first time you roll back a transaction. Finally, as to sequences losing cached values, unless your instance crashes or does a shutdown abort, Oracle should not loose any sequence values. -Mark On Thu, 2002-10-10 at 18:18, [EMAIL PROTECTED] wrote: Actually there is no IO penalty since Oracle has to treat the sequence just like any table with the old LRU algorithm.

We would be using server partitioning, with seperate ORACLE_HOMES for each database (necessary since we have a variety of versions running). The box would be running 1+0, the Sun reps suggest striping across all disks (my first red flag). I hadn't even thought of the problem of not being able to reboot the server, that's an excellent point. Currently we have absolutely no performance problems on our OLTP database. This whole kerfuffle was an outgrowth of my pushing really hard to get a backup box for our datawarehouse (which currently has no standby, no box that it can restored to and no QA box). The suggestion was made that rather than get a separate box for the datawarehouse - get the 15K and have the OLTP and datawarehouse on different partitions. This would certainly speed up the data transfer between them (data is transferred from OLTP - Data Warehouse on a daily basis). We could then put other databases that access my databases on other partitions (several other databases have snapshots on some of my tables). So this would make some processes more efficient, but i/o on my OLTP database is currently tuned so well that it hurts every time I think of giving it up. One spindle has the Oracle executables with the redo logs on the outside of the disk. Another has the various .dat files, shell scripts, etc, with the archive logs on the outside of the disk. Even when we run really intensive updates our wio rarely gets very high. Regarding the load question: We have fairly active transaction activity during the day but most connections are managed by Microsoft Transaction Server in a middle tier so while there are usually app. 200 sessions (including some old client server apps) we rarely have more than 20 or so active at any one time. The datawarehouse has fewer sessions but often has some resource intensive queries running.

RE: Advice needed on move to Sun 15K (losing spindles)
I've cussed and discussed the topic of one big stripe versus multiple small stripes with different people and have yet to come across anyone who has conducted a real test of various scenarios. If you stripe across all disks, then you have the advantage of guaranteed, perfectly balance I/O -- there's certainly something to be said for that! But, then you have a mix of reads and writes going across all drives too. A good argument can be made for taking those parts of the database that tend to be only one kind of operation -- for example, archive logs are writes -- and putting them in their own area. So the drives handling the writing of archived logs are doing only one kind of operation (or are they?!), but you subtract from the drives allocated for other operations. But then there is the issue of: Just exactly how do hard drives work? For example, when doing a large write only operation (like creating an archived log) is the drive really doing this neat and tidy write only, one track after the next, each track right beside the other? Or does the drive actually write a little bit, read a little bit (like a check sum or verify operation), then write some more. And when writing, does it do this smooth, nicely contiguous write, all in one operation? Or does it write a little bit (like an OS buffer full), then move to a different track to update an allocation table (then perhaps read the allocation table), then perhaps go pick up a timing mark, etc.? I suspect some of the answer is dependent on the number of drives and controllers available. (And I must say, that when I read your original question, I wondered why on earth would an organization ready to drop a bundle on a 15K be scrounging for drives -- if I interpreted your post correctly. Is this a Dilbert sort of thing?) The only time I have striped across all drives was the only time I was in a position to make that decision. This was a few years ago, and it was when I did Solaris/AIX admin. It was on a Sparc 4500 with 6 250Mhz CPU's. Since we did not have an Oracle DBA, and I didn't have the time or inclination to devote to setting up and maintaining and official OFA compliant structure, I just made one giant (considered giant at the time) 250 Gb filesystem that would hold all things Oracle and be done with it. I made two 30-drive (8.4 Gb drives) stripes and mirrored them using Solstice Disk Suite. There were 10 wide scsi controllers. Each controller had a 6-drive JBOD attached to it. An eleventh controller had an additional JBOD to be used for hot spares. As you might guess, with a I/O pipe this big, there was no way the 6 CPU's could generate enough I/O to bog things down or even cause a hint of an I/O wait. So the stripe across all drives does work. In my case, I had 60 drives on 10 controllers to work with. Could this have been made more efficient by making a collection of smaller stripes? I have never found anyone who could answer that. The Disk Suite folk can tell you that there is an optimal striping configuration for Disk Suite if we leave Oracle out of the picture. But with Oracle in the picture, who knows? One configuration that sounds reasonable is to put data files with random reads and writes on one stripe, put even numbered redo logs on a stripe, put odd numbered redo logs on a stripe, put archived logs on a stripe. The reasoning (or arm-chair theory) behind the even/odd redo logs is that at a log switch, one file system can be doing writes, while the other is doing reads for the log archiving. This is sorta kinda the way we do things at our shop here with some modifications depending on the app -- like maybe dedicate a stripe to servicing the outrageous temp requirements of a data warehouse (more correctly, a data landfill). If you have only a few drives, my inclination (with no proof whatsoever) is that the one big stripe approach might be a good idea. Thus far, all I have ever gotten on this subject is a lot of religion and very few proven facts. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephen Lee INET: [EMAIL PROTECTED] Fat City Network Services-- 858-538-5051 http://www.fatcity.com San Diego, California-- Mailing list and web hosting services - 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: Making a tablespace read-only - identifying blocking tx
thanks :) it sort of makes sense that you can offline a tablespace with an active transaction in it. You can offline a rollback segment with an active transaction in it, no new transactions can start in that rbs but the one(s) there will finish. With the tablespace, if I remember what I read in the docs correctly (and if the docs are correct), when you offline a tablespace, the active transactions in it continue to process as long as they do not try to modify a block in that tablespace. Once they try that, the transaction dies. Hm, that doesn't sound right.. maybe it's if the blocks from that tablespace are still in the buffer cache? Okay, found it in the 9ir2 Concepts manual, quoted below: When a tablespace goes offline, Oracle does not permit any subsequent SQL statements to reference objects contained in that tablespace. Active transactions with completed statements that refer to data in that tablespace are not affected at the transaction level. Oracle saves rollback data corresponding to those completed statements in a deferred rollback segment in the SYSTEM tablespace. When the tablespace is brought back online, Oracle applies the rollback data to the tablespace, if needed. When a tablespace goes offline or comes back online, this is recorded in the data dictionary in the SYSTEM tablespace. If a tablespace is offline when you shut down a database, the tablespace remains offline when the database is subsequently mounted and reopened. You can bring a tablespace online only in the database in which it was created because the necessary data dictionary information is maintained in the SYSTEM tablespace of that database. An offline tablespace cannot be read or edited by any utility other than Oracle. Thus, offline tablespaces cannot be transposed to other databases. --- Fink, Dan [EMAIL PROTECTED] wrote: First, I ommitted the ;) when replying to Rachel's post. I was just funnin...

RE: Advice needed on move to Sun 15K (losing spindles)
Jay - Will your server partitioning protect the OLTP users from the DW queries? In the normal situation, a company first adds their DW to an existing system. Then they find that the DW doesn't make a good neighbor and buy a separate server. The DW typically does a LOT of full-table scans, so if you share disks, that may not be good for your OLTP. Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED] -Original Message- Sent: Friday, October 11, 2002 11:15 AM To: Multiple recipients of list ORACLE-L I obviously left out a lot of information :). We would be using server partitioning, with seperate ORACLE_HOMES for each database (necessary since we have a variety of versions running). The box would be running 1+0, the Sun reps suggest striping across all disks (my first red flag). I hadn't even thought of the problem of not being able to reboot the server, that's an excellent point. Currently we have absolutely no performance problems on our OLTP database. This whole kerfuffle was an outgrowth of my pushing really hard to get a backup box for our datawarehouse (which currently has no standby, no box that it can restored to and no QA box). The suggestion was made that rather than get a separate box for the datawarehouse - get the 15K and have the OLTP and datawarehouse on different partitions. This would certainly speed up the data transfer between them (data is transferred from OLTP - Data Warehouse on a daily basis). We could then put other databases that access my databases on other partitions (several other databases have snapshots on some of my tables). So this would make some processes more efficient, but i/o on my OLTP database is currently tuned so well that it hurts every time I think of giving it up. One spindle has the Oracle executables with the redo logs on the outside of the disk. Another has the various .dat files, shell scripts, etc, with the archive logs on the outside of the disk. Even when we run really intensive updates our wio rarely gets very high. Regarding the load question: We have fairly active transaction activity during the day but most connections are managed by Microsoft Transaction Server in a middle tier so while there are usually app. 200 sessions (including some old client server apps) we rarely have more than 20 or so active at any one time. The datawarehouse has fewer sessions but often has some resource intensive queries running. If anyone can point me to docs/websites saying that a large caches does *not* make up for fewer disks/spindles I would greatly appreciate it. Currently I'm being told that Sun must know what they're talking about. Thanks again, Jay Miller -Original Message- Sent: Wednesday, October 09, 2002 5:19 PM To: Multiple recipients of list ORACLE-L Others have addressed the performance issues. What about the admin issues? If consolidate to a single server, consider a separate ORACLE_HOME for each database. You may need to apply different patches to fix different problems in various databases. You have this ability now, but will lose it if you consolidate without separate ORACLE_HOME's. Something else you will lose is the ability to reboot the server if needed for a single database. Since you may be moving to a 15k, investigate server partitioning to retain this functionality.

This has some advantages (communication between the various boxes would be much faster) but I have some performance concerns. Specifically, our main OLTP database would go down from 18 spindles to 8 spindles. Mirroring will take away 4 of those leaving 4 spindles. The vendor (Sun) was recommending striping across all 4 spindles. He said we don't need to worry about i/o issues because there will be a large cache. I'm skeptical and argued for cutting them in half (striping 2 and 2). We could then at least seperate the redo logs from the datafiles (probably putting them with the oracle executables and some other files). The Sun rep kept talking up how much more powerful the CPUs were and I kept saying, but we're not CPU bound, we don't need any more CPU. If anyone can either a) tell me I'm worrying for nothing b) recommend a better way to stripe/distribute my files c) provide references or experience to show this is a bad idea I'd really appreciate it.

If you stripe across all disks, then you have the advantage of guaranteed, perfectly balance I/O -- there's certainly something to be said for that! But, then you have a mix of reads and writes going across all drives too. A good argument can be made for taking those parts of the database that tend to be only one kind of operation -- for example, archive logs are writes -- and putting them in their own area. So the drives handling the writing of archived logs are doing only one kind of operation (or are they?!), but you subtract from the drives allocated for other operations. But then there is the issue of: Just exactly how do hard drives work? For example, when doing a large write only operation (like creating an archived log) is the drive really doing this neat and tidy write only, one track after the next, each track right beside the other? Or does the drive actually write a little bit, read a little bit (like a check sum or verify operation), then write some more. And when writing, does it do this smooth, nicely contiguous write, all in one operation? Or does it write a little bit (like an OS buffer full), then move to a different track to update an allocation table (then perhaps read the allocation table), then perhaps go pick up a timing mark, etc.? I suspect some of the answer is dependent on the number of drives and controllers available. (And I must say, that when I read your original question, I wondered why on earth would an organization ready to drop a bundle on a 15K be scrounging for drives -- if I interpreted your post correctly. Is this a Dilbert sort of thing?) The only time I have striped across all drives was the only time I was in a position to make that decision. This was a few years ago, and it was when I did Solaris/AIX admin. It was on a Sparc 4500 with 6 250Mhz CPU's. Since we did not have an Oracle DBA, and I didn't have the time or inclination to devote to setting up and maintaining and official OFA compliant structure, I just made one giant (considered giant at the time) 250 Gb filesystem that would hold all things Oracle and be done with it. I made two 30-drive (8.4 Gb drives) stripes and mirrored them using Solstice Disk Suite. There were 10 wide scsi controllers. Each controller had a 6-drive JBOD attached to it. An eleventh controller had an additional JBOD to be used for hot spares. As you might guess, with a I/O pipe this big, there was no way the 6 CPU's could generate enough I/O to bog things down or even cause a hint of an I/O wait. So the stripe across all drives does work. In my case, I had 60 drives on 10 controllers to work with. Could this have been made more efficient by making a collection of smaller stripes? I have never found anyone who could answer that. The Disk Suite folk can tell you that there is an optimal striping configuration for Disk Suite if we leave Oracle out of the picture. But with Oracle in the picture, who knows? One configuration that sounds reasonable is to put data files with random reads and writes on one stripe, put even numbered redo logs on a stripe, put odd numbered redo logs on a stripe, put archived logs on a stripe. The reasoning (or arm-chair theory) behind the even/odd redo logs is that at a log switch, one file system can be doing writes, while the other is doing reads for the log archiving. This is sorta kinda the way we do things at our shop here with some modifications depending on the app -- like maybe dedicate a stripe to servicing the outrageous temp requirements of a data warehouse (more correctly, a data landfill). If you have only a few drives, my inclination (with no proof whatsoever) is that the one big stripe approach might be a good idea. Thus far, all I have ever gotten on this subject is a lot of religion and very few proven facts. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephen Lee INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services
Session Data Unit and tcp.nodelay
We have third party CAD application called VPM which we are using to organize 3d engineering models. It uses an Oracle database to store some information on locations of models and relationships between parts. We are having some performance problems which seem to point to the database access. With sql tracing turned on, we determined that one of the operations in question used more than 1700 sql statements. The consultant we work with is suggesting that we try to improve the Net8 throughput either by seting tcp.nodelay or by adjusting the size of the Session Data Unit. A quick look at the Net8 manual suggests that both of these could potentially improve throughput by forcing packets to be sent out sooner instead of blocking several requests/responses together.

Yes, it's entirely separate CPUs and disks.

In the normal situation, a company first adds their DW to an existing system. Then they find that the DW doesn't make a good neighbor and buy a separate server. The DW typically does a LOT of full-table scans, so if you share disks, that may not be good for your OLTP. Dennis Williams DBA Lifetouch, Inc.

Re:Session Data Unit and tcp.nodelay
Peter, I've messed with TDU and SDU over the years with mixed and often unpredictable results. TCP.NODELAY has caused some very quirky problems with applications especially when mixed with large values for TDU/SDU. If you do set TDU/SDU set them equal to each other, doing otherwise has again produced some quirky and intermittent problems, like applications appearing to hang or timeout all together. What your trying to control is your server and client's use of the TCP/IP layer. Now if this particular application uses a local database, like our WorkManager CAD application, then these will have no effect since SQL*Net is basically not involved.

We would be using server partitioning, with seperate ORACLE_HOMES for each database (necessary since we have a variety of versions running). The box would be running 1+0, the Sun reps suggest striping across all disks (my first red flag). I hadn't even thought of the problem of not being able to reboot the server, that's an excellent point. Currently we have absolutely no performance problems on our OLTP database. This whole kerfuffle was an outgrowth of my pushing really hard to get a backup box for our datawarehouse (which currently has no standby, no box that it can restored to and no QA box). The suggestion was made that rather than get a separate box for the datawarehouse - get the 15K and have the OLTP and datawarehouse on different partitions. This would certainly speed up the data transfer between them (data is transferred from OLTP - Data Warehouse on a daily basis). We could then put other databases that access my databases on other partitions (several other databases have snapshots on some of my tables). So this would make some processes more efficient, but i/o on my OLTP database is currently tuned so well that it hurts every time I think of giving it up. One spindle has the Oracle executables with the redo logs on the outside of the disk. Another has the various .dat files, shell scripts, etc, with the archive logs on the outside of the disk. Even when we run really intensive updates our wio rarely gets very high. Regarding the load question: We have fairly active transaction activity during the day but most connections are managed by Microsoft Transaction Server in a middle tier so while there are usually app. 200 sessions (including some old client server apps) we rarely have more than 20 or so active at any one time. The datawarehouse has fewer sessions but often has some resource intensive queries running. If anyone can point me to docs/websites saying that a large caches does *not* make up for fewer disks/spindles I would greatly appreciate it. Currently I'm being told that Sun must know what they're talking about. Thanks again, Jay Miller -Original Message- Sent: Wednesday, October 09, 2002 5:19 PM To: Multiple recipients of list ORACLE-L Others have addressed the performance issues. What about the admin issues? If consolidate to a single server, consider a separate ORACLE_HOME for each database. You may need to apply different patches to fix different problems in various databases. You have this ability now, but will lose it if you consolidate without separate ORACLE_HOME's. Something else you will lose is the ability to reboot the server if needed for a single database. Since you may be moving to a 15k, investigate server partitioning to retain this functionality.

This has some advantages (communication between the various boxes would be much faster) but I have some performance concerns. Specifically, our main OLTP database would go down from 18 spindles to 8 spindles. Mirroring will take away 4 of those leaving 4 spindles. The vendor (Sun) was recommending striping across all 4 spindles. He said we don't need to worry about i/o issues because there will be a large cache. I'm skeptical and argued for cutting them in half (striping 2 and 2). We could then at least seperate the redo logs from the datafiles (probably putting them with the oracle executables and some other files). The Sun rep kept talking up how much more
Re: Session Data Unit and tcp.nodelay
Yes, Please do so ! Later versions of Oracle have this already enabled by default I believe. Depending on the delay, the savings/improvements can be great ! First set tcp.nodelay = true, then worry about the SDU/TDU settings. The thing to remember here is that the server and the client need to have the same setting (like with tcp.nodelay). SDU/TDU can be set to 4K as a good start. Anjo. On Friday 11 October 2002 22:05, you wrote: We have third party CAD application called VPM which we are using to organize 3d engineering models.

Re: Session Data Unit and tcp.nodelay
Peter, You'll probably get best results by continuing down the path you've begun. You had SQL-traced a process -- have you used TKPROF to aggregate the information into something useful? Reading a .trc file from SQL trace for performance is like reading a person's genome to find their gender; there are faster ways... To run TKPROF, use the syntax tkprof trc-filename out-filename sort=exeqry,fchqry,execu,fchcu explain=un/pw where: * trc-filename is the filename of the .trc file * out-filename is whatever filename into which you'd like to place the ASCII text output * un is an Oracle account username for TKPROF to use in case it need to run EXPLAIN PLAN on a SQL statement * pw is the password to 'un' The sort= parameter will sort the SQL statements by logical reads, from most to least. Therefore, the worst SQL statements (i.e. the ones consuming the most logical reads) will percolate to the top. This is important, as TKPROF will not the information for you otherwise, leaving you again with the search-the-entire-genome problem you had before. Since you have about 1,700 SQL statements to wade through, I would suggest using the additional print=50 parameter with TKPROF, which will tell TKPROF to only bother summarizing, EXPLAIN PLANing, and printing the top 50 SQL... My guess is that you will see the first 1-3 SQL statements consuming over 90% of all logical reads. Tune those and you will solve your performance issue. Fiddling with obscure parameters (especially networking parameters!) is something to consider *after* the more productive avenues have yielded no results... --- TCP.NODELAY is SQL*Net's implementation of the TCP-level TCP_NODELAY functionality. Essentially, it instructs the network layer not to operate in a synchronous fashion (i.e. send message, await ACK, send next message) but rather to send messages when they are queued. It seems to get used in a lot of Windows applications where folks are clickety-clicking away with their mouse, while prior requests are still being processed. Go ahead and try it, but it will probably have no impact. After all, isn't it more important to deal with the reason that the server-side of a client-server connection is not responding? Also, SDU (session data unit) is the SQL*Net packet sizing. It is also unlikely that adjusting this upwards will help unless you are habitually transferring huge amounts of data to and fro. Ironically, the effect of TCP.NODELAY would probably negate setting SDU higher, and would have the impact of sending more (thus smaller) packets to and fro... Hope this helps... -Tim - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Friday, October 11, 2002 2:05 PM We have third party CAD application called VPM which we are using to organize 3d engineering models.

Particularly in the case where this sequence will see any sort of concurrency, from multiple concurrent sessions accessing it. This is due to the serialization on the SQ enqueue. This will cause far worse scalability issues than any I/O. Not that I/O is insignificant, but in this situation, serialization on the enqueue will be the real showstopper for scalability. As to losing the cached values, well, so what? If your design is such that it's important to have an unbroken contiguous sequence of numbers with no gaps, then I would argue that is a serious design flaw. Also, if that's your requirement, then a sequence is not appropriate, since it can and will end up causing gaps, the first time you roll back a transaction.

trigger and stored procedure
Hi,
Can someone pls help me with the following problem?
thanks
harsh
Requirement:
Whenever a row is deleted from a database table, the client application
shall get the deletion details. Based on the studies done the following
approach is thought to be more appropriate.
1. Create a trigger on the database table. This trigger will call a
stored function.
2. This function will a call a External C procedure.
3. All these triggers and functions are defined in next section.
Description of the Table naren_subscribers.
Name Null?Type
-
USERIDNOT NULL NUMBER(38)
SUBSCRIBER VARCHAR2(30)
HOST NOT NULL VARCHAR2(100)
ALIAS VARCHAR2(30)
AUTHFAILURENUMBER(38)
BLOCKSTATUSNUMBER(38)
The trigger is defined as follows
CREATE OR REPLACE TRIGGER Pre_del_trigger
BEFORE DELETE ON naren_subscribers
FOR EACH ROW
declare
return_value double precision;
Begin
return_value := senddata(:old.userid, :old.subscriber);
end;
/
The function is defined as follows
SQL CREATE OR REPLACE FUNCTION senddata (
arg1 IN NUMBER,
arg2 IN NUMBER )
return DOUBLE PRECISION AS
EXTERNAL NAME senddata
LIBRARY libsenddata
LANGUAGE C;
/
The C procedure is as follows
doublesenddata (OCINumber USER_ID, OCINumber AUTHFAILURE )
{
/* This c procedure opens a socket connection to client application
(which needs the information of the deleted row.) and passes this USER_ID
and AUTHFAILURE */.
}
This C procedure is compiled and senddata.so is generated. This .so is
placed in oracle server by creating a library libsenddata. All OCI related
headers are included in C procedure
Assumptions:
The function senddata that is defined above is sending arguments as
NUMBER. So the equivalent datatype in C is OCINumber.
The problem description:
1. When I am trying to convert the OCINumber to integer in C procedure
using OCI library error is returned.
2. Or is there any way to do this conversion from NUMBER to equivalent C
data type. as well as VARCHAR equivalent C data type.

Controlling Users Logons
Hello Listers, I was asked by a co-worker if there was a way in Oracle to prevent users from connecting to the databases if the same OSUSER has already a created a specified number of sessions to a particular instance. We discussed profiles and resource limits etc. However, the requirement is that the user should a get message that they have exceeded their quota and should not be allowed to log in (there goes the log on trigger). The denial of connection *must* be based on 'OSUSER'. In this environment different OSUSERs use the same Oracle Username for these connections, and the expectation is that the DBA find a solution to enforce some rules. Any tricks? Third party software?

Particularly in the case where this sequence will see any sort of concurrency, from multiple concurrent sessions accessing it. This is due to the serialization on the SQ enqueue. This will cause far worse scalability issues than any I/O. Not that I/O is insignificant, but in this situation, serialization on the enqueue will be the real showstopper for scalability. As to losing the cached values, well, so what? If your design is such that it's important to have an unbroken contiguous sequence of numbers with no gaps, then I would argue that is a serious design flaw. Also, if that's your requirement, then a sequence is not appropriate, since it can and will end up causing gaps, the first time you roll back a transaction. Finally, as to sequences losing cached values, unless your instance crashes or does a shutdown abort, Oracle should not loose any sequence values. -Mark On Thu, 2002-10-10 at 18:18, [EMAIL PROTECTED] wrote: Actually there is no IO penalty since Oracle has to treat the sequence just like any table with the old LRU algorithm.

We would be using server partitioning, with seperate ORACLE_HOMES for each database (necessary since we have a variety of versions running). The box would be running 1+0, the Sun reps suggest striping across all disks (my first red flag). I hadn't even thought of the problem of not being able to reboot the server, that's an excellent point. Currently we have absolutely no performance problems on our OLTP database. This whole kerfuffle was an outgrowth of my pushing really hard to get a backup box for our datawarehouse (which currently has no standby, no box that it can restored to and no QA box). The suggestion was made that rather than get a separate box for the datawarehouse - get the 15K and have the OLTP and datawarehouse on different partitions. This would certainly speed up the data transfer between them (data is transferred from OLTP - Data Warehouse on a daily basis). We could then put other databases that access my databases on other partitions (several other databases have snapshots on some of my tables). So this would make some processes more efficient, but i/o on my OLTP database is currently tuned so well that it hurts every time I think of giving it up. One spindle has the Oracle executables with the redo logs on the outside of the disk. Another has the various .dat files, shell scripts, etc, with the archive logs on the outside of the disk. Even when we run really intensive updates our wio rarely gets very high. Regarding the load question: We have fairly active transaction activity during the day but most connections are managed by Microsoft Transaction Server in a middle tier so while there are usually app. 200 sessions (including some old client server apps) we rarely have more than 20 or so active at any one time. The datawarehouse has fewer sessions but often has some resource intensive queries running. If anyone can point me to docs/websites saying that a large caches does *not* make up for fewer disks/spindles I would greatly appreciate it. Currently I'm being told that Sun must know what they're talking about. Thanks again, Jay Miller -Original Message- Sent: Wednesday, October 09, 2002 5:19 PM To: Multiple recipients of list ORACLE-L Others have addressed the performance issues. What about the admin issues? If consolidate to a single server, consider a separate ORACLE_HOME for each database. You may need to apply different patches to fix different problems in various databases. You have this ability now, but will lose it if you consolidate without separate ORACLE_HOME's. Something else you will lose is the ability to reboot the server if needed for a single database. Since you may be moving to a 15k, investigate server partitioning to retain this functionality.

RE: [Q] ORACLE 9.2 and different version of client?
How were you able to connect INTERNAL or SYS AS SYSDBA from a remote ORACLE_HOME ? INTERNAL from the same O_H didn't require a passsword, per the default behaviour.
