Re: ioug-a question
This is from grandpa's memory: The wait interface (v$system_event, v$session_event, v$session_wait) were introduced in 7.0.12. So if my memory works correctly at this early hour, that was 1992. In 1995, I wrote the Oracle7 wait events and enqueue paper, after Jeff Needham explained a couple of events in the 7.1/7.2 performance and tuning guide. I saw that and decide that we need to do them all. In 1996 I got involved in tuning one of the largest Oracle installations in the world and had to convince the developers that they were doing the wrong thing. So I came up with YAPP (actually even to day that site is still using the initial scripts that we developed for them based on YAPP). I also started to give talks about this way of tuning, I gave talks to support and consultant goups (1997 and later). Then some one in support decided that a white paper was needed and that became the YAPP white paper, published 1998. So a couple of dates and names: 1992 - Juan Loaiza (designed the wait interface) 1994 - Jeff Needham (documented 4/5 events in the performance and tuning guide of 7.1/7.2) 1995/1996 - Oracle7 wait events and enqueue papers (Anjo Kolk) 1996 - YAPP developed onsite at one of the largest OLTP OPS sites in the world 1997/1998 - people insite of Oracle are getting exposed to the wait interface tuning (Mogens Norgaard, Cary Millsap, Shari Yamaguchi) 1998 - white paper was published 1998 - oraperf website 2000 - other companies start to work with the wait interface (Hotsos/Miracle) 2001 - a lot of books are published with wait interface / YAPP methodology 2003 - Richard Niemic rewrites his book and throws out the buffer cache hit ratio and introduces the wait interface, like it was invented yesterday ;-) A couple of things that I have noted over the years: 1) DBAs want tricks (what parameter should I set) to solve performance problems, not a methodology to solve performance problems (learn a man how to fish instead of feeding him) 2) response time tuning is not new, the problem is that most tools out there don't use it and most books don't mention it. It is a complete paradigm shift for most DBA. 3) YAPP/response time tuning is not perfect (by any means), but it is so much better than hit ratio and short list tuning. 4) Response time tuning will become more important as there are now products coming out that do end-to-end response time tuning (actually there already a couple). Watch this space, as things will evolve over the next couple of months/years ! Anjo. Jared Still wrote: Nice post. The 'revolution' is indeed not that new, more of an underground guerilla movement.

The basics revolve around the views v$system_event, v$session_event, and v$session_wait, and v$event_name - and the 10046 event. Rather than try to paraphrase/summarize/expound upon the details, here are some of the best sites for researching the topic. (I'm sure there are other excellent issites, but these are the ones I know about that most certainly qualify.) Historical note: A year ago at the IOUG-A conference, this was considered revolutionary. This year it was the most widely presented and discussed topic at the conference. In fact, the technique has been around for a long time, it just wasn't widely known or accepted. My initiation to it was after an Oracle consultant came out and left something called APS7 installed on an Oracle7 system - in 1997! (Aside: Did APS8 ever exist?). APS7 was written by Milsap's group at Oracle and some of it uses wait-based tuning techniques. Poking around and looking at the scripts opened the door to profound revelation. Motivational scenario: Cast: DBA (you) and PHB (Pointy-haired boss) PHB: This tuning report (or GUI tool) shows the cache-hit ratio as too low. You should tune the database DBA: That is to be expected. Batch manipulated 100 GB of data last night. Cache-hit ratio is a meaningless metric anyway. PHB: But this book says it should be 95%. Besides, we are on the English system - we don't use metric! www.oraperf.com - Anjo Kolk Anjo Kolk's YAPP paper (a pioneering work on the topic).

This unglamorous job involves validating (and sometimes compensating for) what is bad data in Oracle's eyes but not on the mainframe - crazy crap like a date = 22/22/2022. I also find that the mainframe programs are padding null fields with 0's. I wonder how many of you take the route of removing the zeros and storing null in that field? Some of the important numeric fields I think I'll leave that way (past_due_amt, etc.) but several others in this 218-field table are full of zeroes. My gut feel is to null out the insignificant 0'd out fields - that I have pushed to the bottom of the table - to not only save space, but for data integrity. 0 in 75 fields means nothing to me or to anyone else, as far as I can tell.

RE: data cleansing question
Hi Stefan, The EBCDIC-ASCII conversion is handled on the mainframe for me. I am sorry I don't know much about the mainframe environment here, I want to say it's VSAM, there definately is no database.

This unglamorous job involves validating (and sometimes compensating for) what is bad data in Oracle's eyes but not on the mainframe - crazy crap like a date = 22/22/2022. I also find that the mainframe programs are padding null fields with 0's. I wonder how many of you take the route of removing the zeros and storing null in that field? Some of the important numeric fields I think I'll leave that way (past_due_amt, etc.) but several others in this 218-field table are full of zeroes. My gut feel is to null out the insignificant 0'd out fields - that I have pushed to the bottom of the table - to not only save space, but for data integrity. 0 in 75 fields means nothing to me or to anyone else, as far as I can tell.

Re:White papers on industry trends
Valerie, C is still a very heavily used language, although for a complete application I'd probably want to use a C++ variant since they come with screen painter tools. Migrating from C to Forms/Reports would not be unthinkable, but don't underestimate the learning curve. As far as eliminating the external procedure call, if that's the way the application is written, then your stuck and no it will not be eliminated. What may then be more efficient is to take that C code break it up into what is database only and what is C only. Then re-code the application as PL/SQL (or stored Java if your so inclined) keeping in pure C only that which cannot be done otherwise. The industry trend I would have to say is headed towards thin clients and three tier applications which serve internal and external customers and Java. While I agree with the trend in many cases there are too many times that the trend does not really fit the needs. In many a case we end up just moving the bottle neck from one place to the other sometimes making it worse. Case in point is PeopleSoft. There is a panel in the stock room maintenance that updates several tables and rows. Now that is a two tier problem since a lot of data is moving from the server to the client, being processed, and then sent back. But we can id the bottleneck here in that the end user NEEDS a beefy PC. Now you move that into a three tier mess the bottle neck gets harder to find since data moves from the database to the app server, to the client, gets processed sent back to the apps server which does more processing, and then back to the database. Result, you still need the beefy PC on the client side, but you almost need a one to one setup on the app server as well. So then each client actually needs two beefy PC's to do the job in a reasonable manner. YUCK!! Who said thin client was easier cheaper? Must have been some ignorant sales droid at the app server vendor. I note that your address is with the IRS, has the idea of doing Ada cropped up yet? OH, bad joke, it's suppose to be the government's standard programing language as declared by Congress back in the 80's. Then, PL/SQL is the Son of Ada!!

Depends on what you want for Database management - if you need to document schemas or re-create them elsewhere the Free DBATool might be of interest to you. http://www.databee.com/dt_home.htm The DBATool is designed to read an Oracle export file and create executable DDL from it which can rebuild the database - its simple to use and quite useful for DBA's and developers.

Re: ioug-a question
There is always Steve Adams' Oracle8i Internal Services - for Waits, Latches, Locks and Memory from O'Reilly (undoubtably the all-time record holder for information density). It is best considered as Foundations for Advanced Tuning - as described on the cover. Chapter 2 is devoted to waits, but other sections also have wait-related information. I think the best advanced material is still in whitepapers at this point though. Aside: In the migration to wait-based tuning, don't forget that even waits alone don't cover everything. Service time is the other significant component. I like Craig Shallahamer's anallogy - in the grocery store, one waits in line, then gets serviced by the checkout clerk. Even if the wait is moderate, overall response time (grocery store checkout line enqueue to checkout completed) may be poor because of a slow clerk!

SQL giving problem over the database link
Greetings, Here is the scenario. We are trying to insert records into a remote table via database link after selecting the data locally. This query hangs for ever: -- INSERT INTO [EMAIL PROTECTED] SELECT * FROM FW.FWLOT_PN2M WHERE FW.FWLOT_PN2M.fromid = (select fw.fwlot.sysid from fw.fwlot where fw.fwlot.appid = '205956'); select fw.fwlot.sysid from fw.fwlot where fw.fwlot.appid = '205956' : This query returns only one row. SELECT * FROM FW.FWLOT_PN2M WHERE FW.FWLOT_PN2M.fromid = (.) : This select returns 15 rows. If I replace the subquery as follows then it works great : -- INSERT INTO [EMAIL PROTECTED] SELECT * FROM FWLOT_PN2M WHERE fromid = '0e31.900fb406.37bc1803.3074.2026'; I tried to do the same insert locally and it works great : --- INSERT INTO fwlot_pn2m_gene SELECT * FROM FW.FWLOT_PN2M WHERE FW.FWLOT_PN2M.fromid = (select fw.fwlot.sysid from fw.fwlot where fw.fwlot.appid = '205956'); For some reason the combination of database link and the subquery in the select clause is going for full table scan for each occurence of formid.

Re[2]: data cleansing question
Lisa, I'll assume the mainframe application is Cobol or some derivative. Are the original file descriptors available to you? If so they should hold some real clues whether it is a good idea to null out the fields that are all zeroes. If the field is really a number and meant to be used in a calculation, I'd generally leave it as a zero. On the other hand, if the field is described by a list of values for some sort of status, and zero is not listed as a valid code, then I'd null it in a heartbeat. For example, I would not null this field: * SERVICE QUANTITY PASSED BY CLIENT APPLICATION V1.00 * SHOULD BE MINUTES FOR ANESTHESIA V1.00 * 03 CLHC-DET-SERV-QTY PIC 9(4). On the other hand I would certainly null this one: * * OVERALL DISPOSITION OF A CLAIM RETURNED BY IMPULSE * 02 RT-DISPOSITION-CODE PIC 9. 88 RT-DISP-REPRICED VALUE '1'. 88 RT-DISP-NON-REPRICED VALUE '2'. 88 RT-DISP-PENDING VALUE '3'. 88 RT-DISP-ADJUSTED VALUE '4'. 88 RT-DISP-BACK-OUT VALUE '5'. 88 RT-DISP-RE-REPRICEVALUE '6'. 88 RT-DISP-PEND-TIMEOUT VALUE '7'. -rje LK The EBCDIC-ASCII conversion is handled on the mainframe for me.

RE: RE: refcursor rowcount check
Tom, Thanks for taking time off to reply. I had wanted two things - To check rowcount (to enable returning a code for no-rows-found) and secondly, to avoid hitting the database more than once for the same kind of query. I hope you agree that your method also hits db twice. (I open the cursor twice, you do a count once and then open the cursor). This method would not help me scale for bigger data sets and more complex queries. I posted the same question to Thomas Kyte (asktom.oracle.com) and he advises to pass on 'No-rows-found' checking to the calling program. This would avoid any redundant db hits and help scalability. As of now I have decided to adopt this approach - * Perform validation of input parameter * Do a normal fetch of all candidate rows into a temporary table * check the temporary table for count. (this would be a comparitively smaller set) * return ref cursor with either error code or result set. This would allow me to (a) avoid redundant hits (b) adhere to the pre-agreed interface of passing either recordsets or business-rule-error-codes. Thanks again.

A stored procedure accepts parameters and returns refcursors; if no candidate rows are found, then an error code is returned to the calling program. The same cursor variable is used to retrun the rowset or error code. To check if any rows are returned, I use the ROWCOUNT attribute of the cursor variable. Rowcount is not available till I do the first fetch. However the fetch removes the first row from the recordset, in case any rows are present. The 'OUT' variable returned to the calling program has one row less than actual. How to prevent this? Is there any other better way to check if rows are present?

RE: SQL giving problem over the database link
Ashoke - Sympathy, but no firm answers here. I have seen this type of behavior before. Someone mentioned that the underlying problem is that the Oracle optimizer doesn't have enough information to make an intelligent decision in some database link situations.

Re: Execution plan optimizer Question
There are a few conditions which make Oracle use cost based optimisation on a statement even when your system is set to RULE based, or even when you have a RULE hint. To date the list is (I think) limited to statements containing at least one of the following: An IOT A partitioned table The SAMPLE clause A parallel enabled table or index. ANSI outer joins (v9) If any of your queries contain these types of objects, then in the absence of any statistics Oracle will use some default values - so when you get proper values in place the paths may change (in theory for the better).

Re: Currval and buffer gets
Thank all of you for the replies. Unfortunately the program is in c++. Gaja, I will forward your suggestion to the development team. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Sunday, April 21, 2002 8:28 PM Hi Yechiel, Any full-table-scan in Oracle 8i (or below) consumes 4 LIOs to the segment header. This number has reduced to 2 in 9i. Given that the 1 row that you are going after is in 1 data block, there is 1 LIO for the data block itself, given you a total of 5 LIOs. You can verify this by setting 10046 for the session and looking at the trace output. The workaround is to reference x$dual in your application. Alternatively, you can create a view on x$dual, create a synonym for it and then go from there. You will incur some I/O for the first access of the query (with the synonym), but subsequent accesses will incur 0 LIOs against x$dual.

RE: SQL giving problem over the database link
Ashoke, Can you try using an in-line view like this: INSERT INTO [EMAIL PROTECTED] SELECT * FROM FW.FWLOT_PN2M,( select fw.fwlot.sysid sysid from fw.fwlot where fw.fwlot.appid = '205956') WHERE FW.FWLOT_PN2M.fromid = sysid; Havn't tried this, but it is worth a shot. good luck!

I have seen this type of behavior before. Someone mentioned that the underlying problem is that the Oracle optimizer doesn't have enough information to make an intelligent decision in some database link situations. Sometimes I've given up in frustration and just pulled the entire table to the other side of the link. I haven't tried this, but I wonder if a hint might help its behavior. Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED] -Original Message- Sent: Monday, April 22, 2002 10:48 AM To: Multiple recipients of list ORACLE-L Greetings, Here is the scenario.

RE: RE: refcursor rowcount check
Madhu, I agree that the suggestion I proposed performs two queries. And I'm glad you have found a work-around (having your application do what it should do). I am guessing that my proposal would not cost very much to run. If you think about, the first query (select count(*)) would certainly use any indexes it could (and, as a by-product, they index segments would be sitting in the SGA). The second query would then re-use these same index segments. Since they have already been loaded in the SGA, their re-use would not cost all that much - unless of course, you are returning *millions* of rows. Most on-line applications do not return that much data to the screen, so I would guess that it would work just fine. Glad I could help in any (small) way. Tom Mercadante Oracle Certified Professional -Original Message- Sent: Monday, April 22, 2002 12:55 PM To: Multiple recipients of list ORACLE-L Tom, Thanks for taking time off to reply. I had wanted two things - To check rowcount (to enable returning a code for no-rows-found) and secondly, to avoid hitting the database more than once for the same kind of query. I hope you agree that your method also hits db twice. (I open the cursor twice, you do a count once and then open the cursor). This method would not help me scale for bigger data sets and more complex queries. I posted the same question to Thomas Kyte (asktom.oracle.com) and he advises to pass on 'No-rows-found' checking to the calling program. This would avoid any redundant db hits and help scalability. As of now I have decided to adopt this approach - * Perform validation of input parameter * Do a normal fetch of all candidate rows into a temporary table * check the temporary table for count. (this would be a comparitively smaller set) * return ref cursor with either error code or result set. This would allow me to (a) avoid redundant hits (b) adhere to the pre-agreed interface of passing either recordsets or business-rule-error-codes. Thanks again.

A stored procedure accepts parameters and returns refcursors; if no candidate rows are found, then an error code is returned to the calling program. The same cursor variable is used to retrun the rowset or error code. To check if any rows are returned, I use the ROWCOUNT attribute of the cursor variable. Rowcount is not available till I do the first fetch. However the fetch removes the first row from the recordset, in case any rows are present. The 'OUT' variable returned to the calling program has one row less than actual. How to prevent this? Is there any other better way to check if rows are present?

RE: White papers on industry trends
Title: RE: White papers on industry trends Dick, Thanks for the information. You make a good point about learning curve (which is a concern the client has too) and about breaking up the C code. Yes, I am a contractor with the IRS but this project was always written in C. Never in Ada.. thank goodness... Currently the system runs on an Informix database but will be converted to Oracle since it is the new IRS system of choice. (Good move) I was just concerned that keeping the C would be keeping a dinosaur in the backyard out of fear of a learning curve. We have the time to convert it and deal with the learning curve. The C code is pretty much spaghetti code after 17 years of band-aids and duct tape. It desperately needs to be reworked/redesigned not to mention adding Pro*C. We have a sister project that chucked all their C code and rewrote everything in Java. It was tough but the payoff was great. We may have to decide on a module-by-module basis. Ada... now there's a dinosaur if I ever heard of one... :) Val -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, April 22, 2002 10:33 AM To: Multiple recipients of list ORACLE-L Subject: Re:White papers on industry trends Valerie, C is still a very heavily used language, although for a complete application I'd probably want to use a C++ variant since they come with screen painter tools. Migrating from C to Forms/Reports would not be unthinkable, but don't underestimate the learning curve. As far as eliminating the external procedure call, if that's the way the application is written, then your stuck and no it will not be eliminated. What may then be more efficient is to take that C code break it up into what is database only and what is C only. Then re-code the application as PL/SQL (or stored Java if your so inclined) keeping in pure C only that which cannot be done otherwise. The industry trend I would have to say is headed towards thin clients and three tier applications which serve internal and external customers and Java. While I agree with the trend in many cases there are too many times that the trend does not really fit the needs. In many a case we end up just moving the bottle neck from one place to the other sometimes making it worse. Case in point is PeopleSoft. There is a panel in the stock room maintenance that updates several tables and rows. Now that is a two tier problem since a lot of data is moving from the server to the client, being processed, and then sent back. But we can id the bottleneck here in that the end user NEEDS a beefy PC. Now you move that into a three tier mess the bottle neck gets harder to find since data moves from the database to the app server, to the client, gets processed sent back to the apps server which does more processing, and then back to the database. Result, you still need the beefy PC on the client side, but you almost need a one to one setup on the app server as well. So then each client actually needs two beefy PC's to do the job in a reasonable manner. YUCK!! Who said thin client was easier cheaper? Must have been some ignorant sales droid at the app server vendor. I note that your address is with the IRS, has the idea of doing Ada cropped up yet? OH, bad joke, it's suppose to be the government's standard programing language as declared by Congress back in the 80's. Then, PL/SQL is the Son of Ada!!

Re: Currval and buffer gets
Hello Yechiel, X$DUAL is an Oracle-internal table in the SGA and will not be shown in an ALL_OBJECTS listing. Obviously, you need to be SYS to see this. You can do a describe as SYS and you will see it. Which is the reason why I recommended creating a view and a public synonym on the view, so that the application may reference it without any issues. Cheers, Gaja --- Yechiel Adar [EMAIL PROTECTED] wrote: Hello Gaja I could not find x$dual. Did select on all_objects got zip. Oracle 8.1.6.3.4 on NT. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Sunday, April 21, 2002 8:28 PM Hi Yechiel, Any full-table-scan in Oracle 8i (or below) consumes 4 LIOs to the segment header. This number has reduced to 2 in 9i. Given that the 1 row that you are going after is in 1 data block, there is 1 LIO for the data block itself, given you a total of 5 LIOs. You can verify this by setting 10046 for the session and looking at the trace output. The workaround is to reference x$dual in your application. Alternatively, you can create a view on x$dual, create a synonym for it and then go from there. You will incur some I/O for the first access of the query (with the synonym), but subsequent accesses will incur 0 LIOs against x$dual.

OT: Windows Patches and Oracle
Hello everyone, I asked our sysadmin to keep me updated on all OS patches he plans to apply to our test and production servers, to allow ample testing and research prior to implementation in production. (Testing patches is a new idea to him.) Below is a list of all the patches he wants to install. I already nixed having IIS on this server - who needs the headache?? I am now questioning the need for DirectX and .NET. I am not going to argue with him over the security patches, but can someone verify that DirectX and .NET indeed are extraneous to a server that is dedicated to running an Oracle database? I just want to keep this server as clean as possible and I feel like a ton of useless windows crap is ending up on it, taking up disk and resources. However, I can't confirm that. I am borderline clueless when it comes to Windows. To keep traffic down, please reply to me directly. Thank you very much...

Re: Re[2]: MySQL vs. Oracle database
Plus, I had some experience with a Supra-ized Cincom database. It was a
nightmare. We wound up reverting to their more primitive (but stable)
database - Total. There was a newer pass at Supra in the early '90s that
was supposed to turn a Total database into a relational database and this
looked promising...but I moved on to the Oracle world...

Re: ioug-a question
Ah, good point about Jeff Needham who's now partner with James Morle (ScaleAbilities). I hear rumors that Jeff might also be going to the Database Forum in Sydney. We should have a historical gathering there where we wait in line while everybody else get serviced. Mogens Anjo Kolk wrote: This is from grandpa's memory:The wait interface (v$system_event, v$session_event, v$session_wait) wereintroduced in 7.0.12. So if my memory works correctly at this early hour, thatwas 1992. In 1995, I wrote the Oracle7 wait events and enqueue paper, after JeffNeedham explained a couple of events in the 7.1/7.2 performance and tuningguide. I saw that and decide that we need to do them all. In 1996 I gotinvolved in tuning one of the largest Oracle installations in the world and hadto convince the developers that they were doing the wrong thing. So I came upwith YAPP (actually even to day that site is still using the initial scriptsthat we developed for them based on YAPP). I also started to give talks aboutthis way of tuning, I gave talks to support and consultant goups (1997 andlater). Then some one in support decided that a white paper was needed and thatbecame the YAPP white paper, published 1998.S o a couple of dates and names:1992 - Juan Loaiza (designed the wait interface)1994 - Jeff Needham (documented 4/5 events in the performance and tuning guideof 7.1/7.2)1995/1996 - Oracle7 wait events and enqueue papers (Anjo Kolk)1996 - YAPP developed onsite at one of the largest OLTP OPS sites in the world1997/1998 - people insite of Oracle are getting exposed to the wait interfacetuning (Mogens Norgaard, Cary Millsap, Shari Yamaguchi)1998 - white paper was published1998 - oraperf website2000 - other companies start to work with the wait interface (Hotsos/Miracle)2001 - a lot of books are published with wait interface / YAPP methodology2003 - Richard Niemic rewrites his book and throws out the buffer cache hitratio and introduces the wait interface, like it was invented yesterday ;-)A couple of things that I have noted over the years:1) DBAs want tricks (what parameter should I set) to solve perform ance problems,not a methodology to solve performance problems(learn a man how to fish instead of feeding him)2) response time tuning is not new, the problem is that most tools out theredon't use it and most books don't mention it. It is acomplete paradigm shift for most DBA.3) YAPP/response time tuning is not perfect (by any means), but it is so muchbetter than hit ratio and short list tuning.4) Response time tuning will become more important as there are now productscoming out that do end-to-end response time tuning (actually there already acouple).Watch this space, as things will evolve over the next couple of months/years !Anjo.Jared Still wrote: Nice post.

Scheduling for Statspack
Hi, I have a question with regard to the best scheduling for Statspack. I am running Oracle 8.1.6.2 on Hp UX11. I see that the oraperf site recommends no more than intervals of (5 to 15 minutes) to tune performance problems. Does setting up a schedule with 96 or 288 snaps at level 5 put a heavy load on the system? I am still trying to get some performance problems with disk i/o and latch contention sorted out, but I also want to keep baseline statistics to monitor how well my tuning effort is proceeding. What period would you recommend setting dbms jobs to monitor a busy production system? How about hourly for the snapshots and then use a 1 or 2 hour block to keep for historical data. I plan on purging every 14 days but I want to keep something for each day. If I do this how will I be able to tune for performance problems?

Patch Install (8.1.7.3) and oraInventory
I am trying to install the 8.1.7.3 upgrade patch. Unfortunately, somewhere down the road I have lost my oraInventory directory. The installer says 'There are no patches to be applied. Metalink says that the only way to get your oraInventory back is to reinstall the current version of Oracle and all patches. Does anyone know of a way to get the patch to install without the inventory history? Or a way to rebuild the oraInventory directory? This is a cloned database and I already tried copying the oraInventory directory from another instance, but the files have the installation directory hardcoded and the oraInventory files are binary so I can't change them.

Is there a way to get a listing of installed components?

RE: DB_BLOCK_CHECKING and DB_BLOCK_CHECKSUM
Beth - Well, you can get ahead of the curve and report back to the rest of us. Since you mentioned both parameters, I'm assuming that you are considering turning DB_BLOCK_CHECKSUM=true and leaving DB_BLOCK_CHECKING=false. Igor - Thanks for pointing out that the DB_BLOCK_CHECKSUM parameter is turned on by default in 9i I guess my initial reaction was that of the crusty old DBA. I just get suspicious of something that will help me prevent a problem that I'm not experiencing. I've got bitten a few times on that one. I pasted the documentation in below in case anyone wants to see what these two parameters do. Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED] From the Oracle 9i Documentation: DB_BLOCK_CHECKSUM (default is true in 9i, false in 8i) determines whether DBWn and the direct loader will calculate a checksum (a number calculated from all the bytes stored in the block) and store it in the cache header of every data block when writing it to disk. Checksums are verified when a block is read-only if this parameter is true and the last write of the block stored a checksum. In addition, Oracle gives every log block a checksum before writing it to the current log. If this parameter is set to false, DBWn calculates checksums only for the SYSTEM tablespace, but not for user tablespaces. Checksums allow Oracle to detect corruption caused by underlying disks, storage systems, or I/O systems. Turning on this feature typically causes only an additional 1% to 2% overhead. Therefore, Oracle Corporation recommends that you set DB_BLOCK_CHECKSUM to true. DB_BLOCK_CHECKING (default value is false) controls whether Oracle performs block checking for data blocks. When this parameter is set to true, Oracle performs block checking for all data blocks. When it is set to false, Oracle does not perform block checking for blocks in the user tablespaces. However, block checking for the SYSTEM tablespace is always turned on. Oracle checks a block by going through the data on the block, making sure it is self-consistent. Block checking can often prevent memory and data corruption. Block checking typically causes 1% to 10% overhead, depending on workload. The more updates or inserts in a workload, the more expensive it is to turn on block checking. You should set DB_BLOCK_CHECKING to true if the performance overhead is acceptable. -Original Message- Sent: Monday, April 22, 2002 3:25 PM To: Multiple recipients of list ORACLE-L Thanks Dennis.

RE: data cleansing question
Stefan, I've got a question regarding your migration host - oracle, since I'll have the same problem in the near future. How do you deal with the EBCDIC to ASCII problem ? Do you migrate from VSAM or DB2 ? Which version of Oracle are you on ? Can't reply to the second one, but take a look at the 'dd' UNIX command with the conv=ascii parameter for EBCDIC to ASCII conversions. Do be careful though: Stuff can be present in 7-bit and work differently...

char vs. varchar2
Is there any overhead (ie. internal conversion) in comparing a char to a varchar2? We found an instance where a primary key in one table is defined as char(2) and the foreign key referencing it from another table is varchar2(2). We are going to change it, but I'm curious what, if anything, happens when resolving the integrity?

RE: Anything new from IOUG? + OWI Born!! (Anjo/Mogens, please n
Mark, This is from a first-timer at IOUG, so I may be way off here. A lot of marketing blurb was thrown out at IOUG (probably a lot less than usual, and *much* less than Oracle OpenWorld in any case!). As for tools, many vendors were flogging the same ones, improved versions maybe. One which did make us say 'wow' was StorageXpert from Quest. IMHO, this is an excellent tool, engineered by our very own Gaja. I believe details are at the Quest site at www.quest.com. If you have EMC disks and are facing performance problems, I believe there is the best there is. (Or even if you have other storage devices, it would still give you the hotspots). And NO, I do NOT work for Quest, nor have Quest stock! And for others, I believe this was a major turning point and an eye-opener as far as the Wait Interface goes (This has (un)officially been renamed to OWI as per Kirti's slides :-). Most attendees 'saw the light' as far as CHR (Cache Hit Ratio) goes, and there were two distinct camps after the first few days - the 'CHR' and 'OWI'. No prizes for guessing who won the day! The massive number of defections and the absolute absense of CHR-based-discussions at the Performance round tables was clear evidence that OWI is here to stay! (Mr. R might still rewrite that book sooner than later!) About 20 Listers met for dinner on Sunday night (and again in a larger group at the SeaWorld bash). The meeting was characterized by geek-talk such as 'Can you fit us all in one extent?' i.e. 'can we all sit at one table?'), 'Please coalesce' - 'please move in so that more people can fit into the aisle seats'. Oh Boy, that WAS a lot of fun!

Re:RE: White papers on industry trends
Val, For a real dinosaur, try Jovial. Created by Teledyne for the USAF to improve the performance of ECM equipment. Last used in the late 70's after a fitful 10 year lifespan. If I remember correctly there were about 50 people in the world who knew it. As for your C code, take a serious look at what is being done. I took a number of C programs and after disecting them re-wrote then in PL/SQL and C. In the end it was a lot less code the time to execute dropped from minutes to seconds. Dick Goulet Reply Separator Author: Webber Valerie H [EMAIL PROTECTED] Date: 4/22/2002 9:30 AM Dick, Thanks for the information. You make a good point about learning curve (which is a concern the client has too) and about breaking up the C code. Yes, I am a contractor with the IRS but this project was always written in C. Never in Ada.. thank goodness... Currently the system runs on an Informix database but will be converted to Oracle since it is the new IRS system of choice. (Good move) I was just concerned that keeping the C would be keeping a dinosaur in the backyard out of fear of a learning curve. We have the time to convert it and deal with the learning curve. The C code is pretty much spaghetti code after 17 years of band-aids and duct tape. It desperately needs to be reworked/redesigned not to mention adding Pro*C. We have a sister project that chucked all their C code and rewrote everything in Java. It was tough but the payoff was great. We may have to decide on a module-by-module basis. Ada... now there's a dinosaur if I ever heard of one... :) Val -Original Message- Sent: Monday, April 22, 2002 10:33 AM To: Multiple recipients of list ORACLE-L Valerie, C is still a very heavily used language, although for a complete application I'd probably want to use a C++ variant since they come with screen painter tools. Migrating from C to Forms/Reports would not be unthinkable, but don't underestimate the learning curve. As far as eliminating the external procedure call, if that's the way the application is written, then your stuck and no it will not be eliminated. What may then be more efficient is to take that C code break it up into what is database only and what is C only. Then re-code the application as PL/SQL (or stored Java if your so inclined) keeping in pure C only that which cannot be done otherwise. The industry trend I would have to say is headed towards thin clients and three tier applications which serve internal and external customers and Java. While I agree with the trend in many cases there are too many times that the trend does not really fit the needs. In many a case we end up just moving the bottle neck from one place to the other sometimes making it worse. Case in point is PeopleSoft. There is a panel in the stock room maintenance that updates several tables and rows. Now that is a two tier problem since a lot of data is moving from the server to the client, being processed, and then sent back. But we can id the bottleneck here in that the end user NEEDS a beefy PC. Now you move that into a three tier mess the bottle neck gets harder to find since data moves from the database to the app server, to the client, gets processed sent back to the apps server which does more processing, and then back to the database. Result, you still need the beefy PC on the client side, but you almost need a one to one setup on the app server as well. So then each client actually needs two beefy PC's to do the job in a reasonable manner. YUCK!! Who said thin client was easier cheaper? Must have been some ignorant sales droid at the app server vendor. I note that your address is with the IRS, has the idea of doing Ada cropped up yet? OH, bad joke, it's suppose to be the government's standard programing language as declared by Congress back in the 80's. Then, PL/SQL is the Son of Ada!! Dick Goulet Reply Separator Author: Webber Valerie H [EMAIL PROTECTED] Date: 4/22/2002 5:28 AM Are there any white papers on industry trends for architecture including programming languages. I'm working on a project that is in the early stages of a redesign. The current application uses C code entirely including user interface. The client is sold on Oracle Forms/Reports but is reluctant to trash the C code and start from scratch. This is the first such redesign in 17 years. Does a 3 tier architecture using iAS minimize or eliminate the cost in performance of the external procedure call to the C program from a stored procedure? Any information will be helpful...

Re: DB_BLOCK_CHECKING and DB_BLOCK_CHECKSUM
Title: DB_BLOCK_CHECKING and DB_BLOCK_CHECKSUM
DB_BLOCK_CHECKSUM = no overhead worth
mentioning
DB_BLOCK_CHECKING = equivalent to 10210 (check data
block integrity), 10211 (check index block integrity), and 10212 (check cluster
integrity) events
The former (DB_BLOCK_CHECKSUM) is useful if you
suspect that something might be corrupting a database block while it is residing
on disk. The checksum is calculated by the writing process (i.e. DBWR)
upon write to datafile and re-calculated/verified by server processes upon
read. It will raise an ORA-01578 error upon read...
The latter (DB_BLOCK_CHECKING) is intended to cause
additional integrity checks while the database block resides in a buffer in the
SGA, so it could be useful if you believe that there is some form of memory
corruption involving the Buffer Cache. Other events for checking for
possible memory corruption include 10235 ("check memory manager internal
structures") and 10049 ("Use the OS memory protection (if available) to protect
library cache memory heaps that are pinned.")...
There is an undocumented parameter
("_db_always_check_system_ts") which defaults to TRUE, causing the constant
DB_BLOCK_CHECKING in the SYSTEM tablespace, from v8.1.6 onwards.
Thiscaused some problems for those upgrading from v8.0.x and v8.1.5 to
v8.1.6 when any kind of corruption exists in the SYSTEM tablespace, because a
bug introduced late in 7.3.x (or early 8.0.x?) causes corruption in
SYSTEM. Note #96117.1 on MetaLink has more info on this.
