Re: Perf Advice Needed: cache buffers chains, high waits, _db_block_hash_buckets
Really, The only thing to do is fix the SQL. Each logical I/O or buffer get results in a cache buffer chain latch get. So by doing less LIO, you will get fewer latch gets and as a result fewer sleeps on latches. This is how you fix the *problem*. You can also fix the *symptom*: bump up _spin_count (assuming that you run on a SMP) or set _db_ block_hash_latches to a higher value. Fixing the SQL is the right way to go. Are you shooting for a 99.9 percent buffer cache hit ratio ? If you are than that could also be a reason for the problem. Oh and there is a bug in Oracle 8.1.6/8.1.7 I believe that causes an additional buffer get for the index root block (assuming that the hash latches with the high sleeps cover index root blocks).

Checking with all_objects, I'm noticing that these blocks are scattered in some of the more important (and most-accessed) tables and indexes - The other latch children that have high sleep counts also have 30-50 buffers in their chains Questions: - to me, 66 seems awfully high - is it? - the sleep count is obviously high from what I can tell - is it definitely tied to the buffer chain this latch is protecting being so long and just happening to be 66 buffers that are mostly important tables and indexes? - I haven't set it by hand, but _db_block_hash_buckets = 720896 and this is 11 * 2^16. Everything I've read says it should be a prime number (and that jives with my comp sci background) - why is it not prime, why is it exactly twice db_block_buffers? - the number of children for cache buffers chains is 4096. Now, increasing that could have a positive effect on distributing the contention, but since the sleps are so heavily skewed to only a few of the children as it stands, I don't get the feeling that's the right fix. Anyone have any advice to offer? Pages/URL's that can help give some advice? It's worth noting that these latches are basically non-existant as wait events at low load - log file sync is about the only wait event I see at low loads, and I'm working on reducing my commit counts much further to help tackle that.

Hello Don In a more serious mood: DO IT. I also had some arguments with my boss over the years and except for 2-3 cases (in 20 years) that I told my boss that I will not do something and if he wants it he can do it himself, my motto was if he wants to waste resources for something that is obviously an error let him waste it.

max open cursors exceeded
Title: max open cursors exceeded Hi! We are having problems with Oracle interMedia text and open cursors used: our instance has open_cursors et to 1000. We check the number of open cursors regularly using: break on report comp sum of curs on report select User_Name, SID, count(*) Curs from v$open_cursor group by User_Name, SID order by User_Name, SID; the corresponding sql text is extracted from the dd using: select SID, User_Name, SQL_Text from v$open_cursor order by User_Name, SID, SQL_Text; ususally, the number of open cursors used is about 300. if we are using interMedia text option, it usually rises and rises every day. after bouncing the instance, we are back to slightly below 300. Questions: a) MAX_OPEN_CURSORS is set to 1000 - when exceeding that threshold, we're experiencing problems; how can we monitor which users uses up all the cursors (and how many). b) What exactly is displayed when querying v$open_cursor? - I know htat there are parsed statements of the user/session - but this should be more than just a PL/SQL declare cursor... open...fetch...close cursor, right? What about statements issued in SQL*Plus or through JDBC etc.? c) The results from v$open_cursor is equivalent to the currently running transaction, right? So when are those entries removed again? When the transaction commits or when the sessions ends? Or when issuing a PL/SQL close cursor. Or are those entries overwritten? by whom? when? d) what does querying select * from v$sql_cursor return? Any ideas? This is 8.1.7 on Sun Solaris. Thanks, Helmut
RE: Upgrade directly to 8.1.7.3?
Hello Barbara I did not worked with 8.1.7 but I installed patches in 8.1.6. I think (please check this) that maybe 8.1.7.3 is just a binary and external files replacement and no scripts are run. In this case you need to run the scripts that convert the DB from 8.0.5 to 8.1.7 because they are not part of 8.1.7.3. Anyway, I would suggest that you convert the DB to 8.1.7.2 and if everything is OK upgrade later to 8.1.7.3. Upgrade like this does not need a new home and 1GB on disk.

I hung in there because the company was paying for my masters degree at the time. Later, after I got the degree, I left for greener pastures within the company. In the exit interview my former boss accused me of abandonning him, congratulated me on my move, and literally wept at my departure. He confessed he had been trying to get my goat because he was a 20 year military man who managed by intimidation. But he respected me because I was never intimidated, always stood my ground, behaved as a gentleman, and served him faithfully (his words). Two years later I saw my former boss from hell on the 6 o'clock news being put into a police squad car and with yellow crime scene ribbons around his house. Turns out that while he was being laid off he said things which were interpreted as threats on the lives of certain managers. This was taken seriously and the police confiscated all his guns.

Pages/URL's that can help giv e someadvice?It's worth noting that these latches are basically non-existant aswait events at low load - "log file sync" is about the only waitevent I see at low loads, and I'm working on reducing my commitcounts much further to help tackle that.Thanks!!James--James Manning [EMAIL PROTECTED]GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4--Please see the official ORACLE-L FAQ: http://www.orafaq.com--Author: James Manning INET: [EMAIL PROTECTED]Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051San Diego, California-- Public Internet access / Mailing ListsTo REMOVE yourself from this mailing list, send an E-Mail messageto: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and inthe message BODY, include a line containing: UNSUB ORACLE-L(or the name of mailing list you want to be removed from).

Tracing sequences (was re: freelist tesing)
Anjo has convinced me that I was indeed barking up the wrong tree (and even if I was the tree didn't care) He lead me into tests that shows my problem exhibits exactly the same characteristics of trying to insert the same value into a unique index simultaneously. That somehow, one user does an insert with one value, and before he commits, another session (usually different user -- not always) tries to insert the same value. Previously I had examined the developers code and convinced myself that this could not be the case as he selects a sequence nextval into a variable, then immediately uses that variable to create a the value list for the insert. I haven't found anything that makes me want to mistrust a sequence nextval. (If anyone knows of one in 8.0.5 on Solars 2.7 please let me know.) So I've got to mistrust something going on in the developers VB based COM object running under MTX serving up ASP pages for IIS. (Notice the long string of MS products there and you can guess how that influences my suspicions.) Since I've come to this realization, the event has not recurred, so I don't have any statistics. But we do know that when it starts, we see incidents from all 8 webservers simultaneously. Past evidence collected for a blocker and a blocked session shows that they were on the same webserver, but that's just 1 data point and we don't have any other to confirm or deny that relationship. Also when it starts, it happens at a furious rate, dozens of sessions at once. Then it suddenly stops. Curiously, the same applications on the same webservers are handling 30 other databases which experience no problems. This points me back to the database. sigh One of the things I would like to do, is to record what the database thought it answered for the select of the sequence nextval, and have that for comparison when the application tries to do its insert. My dream would be to have a trace/log/journal/something that recorded the nextval returned,user,session,serial#,and sysdate for every time the sequence was read. This would allow me to see discrepancies in the select/insert and sessions that were trying to insert without actually making the select. Has anyone tried this level of tracing/logging before? -rje -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Robert Eskridge 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: Old Chestnut: Tablespace Fragmentation
If you have only 1 Table in that Tablespace and only 1 File on that disk, even if you had multiple extents, you might expect them to be contiguous. Then, the only issue would be that the extent size should be a proper multiple of db_block_size*db_file_multiblock_read_count (or max_io_size).

But what if: Data Warehouse, one big table on a single disk, full table (batch) scan, no concurrent transactions on the database (so no contention for the disk), no fragmentation at the file system level, initially empty buffer cache (startup), read-only operation so DBWR isn't doing anything on this disk. Basically I want to read one data file from end to end. Surely it would make sense to have the disk read moving smoothly from one end of the disk to the other rather than bouncing about all over the place as it may do with multiple extents randomly allocated.

RE: Manager decrees his data warehouse design. Help!
No, I'm not being facetious, I'm being honest (welcome to my world)... that is the exact statement that was given in the meeting... that I was not invited to, but my boss was. And the statement came with preening and posturing, because it was the model that the author of the statement came up with. My input... I just have to make it work, my input is usually irrelevant, I'm JUST the DBA. The phrase April, Sit down and shut up usually crops up when I try to make a point in our brainstorming meetings. BENCHMARKS? Yeah... okay. This POC was done on the AIX-RS6000 equivalent of a 486. ONE cpu, and I had to get REAL creative just to get the DASD to give them room to make it RUN. Benchmarks come later... when I finally can get them on a test box. I will get benchmarks in the big real POC that starts in April... probably. We were not to keep statistics on the load time, that was irrelevant... just get data in it. The only important statistics were on query times. The way I have it figured it was probably closer to blocks per row in this DB Instance than rows to blocks (4k blocks, on average 15(bytes)*650(columns per row average containing data)). Most queries that we believe will run will bring back, at most, 50 of those columns... most not that many. I gave them statistics on IF we could get it to ever load we would end up with a table with 560 gig per year growth and indexes on that table of roughly a terabyte growth per year if they indexed it the way they wanted to... AND it would ever load or the indexes would ever build... but I didn't have FACTS to support it, only extrapolations on existing data. Until I could prove it wouldn't work, we would go on the premise that it would. The TEAM knows reality... but the LEADER doesn't seem to feel that reality should play a part. Sorry... yesterday was a bad day and this project is becoming very... intense... but I really agree that there are times when I don't know what I am even here for... other than to smile and nod and TRY to make what they design run. ajw -Original Message- Sent: Wednesday, February 27, 2002 12:29 PM To: Multiple recipients of list ORACLE-L April, I sincerely hope you're being facetious with the statement that queries run so much faster if you take all the joins out 1000 columns!?

MS Access migration to oracle
I've been told to migrate one MS-Access 97 database to oracle. Oracle Migration Workbench did the trick in an extremely clean, quick and complete way. Tables are created, populated with data and it is now when the problem starts. The people that were using this Access database were doing so by means of an ancient VB piece of ... code and they don't want or they don't know to adjust it. They expect the program to somehow find the new Oracle 8.1.7.3 instance and continue to work as it did before. I created a new access database containing ODBC links to the Oracle tables, but the program is complaining that the links are read only. Is there any way in this world or beyond to make these tables writable? I'm inclined to tell them that they should do some coding, which is very likely to make them go back to Access. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Gogala, Mladen 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).

By monitoring v$open_cursor b) What exactly is displayed when querying v$open_cursor? - I know htat there are parsed statements of the user/session - but this should be more than just a PL/SQL "declare cursor... open...fetch...close cursor", right? What about statements issued in SQL*Plus or through JDBC etc.? v$open_cursor displays ALL the cursors for a given session, not justthe explicite PL/SQL or PRO*C stuff.A cursor is needed for EVERY SQL STATEMENT. The only cursor not displayed by v$open_cursor is the DBA himself/herself, especially if he has to support tools that do their own multiplexing, like Forte. c) The results from v$open_cursor is equivalent to the currently running transaction, right? So when are those entries removed again? When the transaction commits or when the sessions ends? Or when issuing a PL/SQL "close cursor". Or are those entries overwritten? by whom? when? An implicit cursor is closed when another statement is opened and re-parsed. If you take a look at v$session, you'll find that iscontainsthe "current SQL" address. That is, basically, the open cursor that the session is currently executing. When the next SQL comes in, this cursor will be closed, SQL put in the library cache and a new cursor will be allocated. d) what does querying "select * from v$sql_cursor" return? That query will usually return enough information for your screen to join it's ancestors and will leave you wandering why is that SQL*Plus does not have "clear" or "cls" command. Any ideas? Yes. I want to win a lottery jackpot and start my own business in close proximity to the Waikiki beach.

if you return the seq nextval by a function you can track it. So, let your developers avoid 'select seq.nextval into ... from dual;' syntax.

Non-partitioned table to Hash Partitioned table
Hello! I am trying to figure out the best way to convert a non-partitioned table with approx 20 million rows into a hash-partitioned table. This should be done with minimal down-time. This will be in an Oracle 9i environment done at a time when only SELECTs are occuring on the table. The best way I can figure is to create a second table and copy the data over; create the indexes; and rename the tables. I would appreciate any hints on what section of TFM to read.

Re: SNP0...SNPx Memory Hogs
At least in 8.0.x the oracle intelligent agent process are dbsnmp processes. Are you sure that these are oracle processes and not OS related. Ruth - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Wednesday, February 27, 2002 4:20 PM 8.1.7.2.5 under Win2k Server I just discovered that my four SNP processes were sitting around, doing no work, taking up about 500MB of RAM. Is this normal? In Task Manager, the Oracle process was showing to be using about 1.4GB. After I issued Alter System Set Job_Queue_Processes=0 it shrank to about 900MB. I then issued Alter System Set Job_Queue_Processes=4, but the Mem Usage stayed the same. None of those SNP processes had done any work (i.e., run any jobs) for about 10 hours. I would have expected the SNP processes to release memory when their jobs finish. I've been trying to figure out what processes were chewing up RAM, ramping up over the course of 3 or 4 days. Some Java processes that we run were found to be hogs, but after I got the developers to disconnect/reconnect occasionally, those sessions were OK. I finally found the culprits when I was checking sessions' session pga memory. A couple of sessions were using about 200MB each. I checked to see what SQL they'd been running and found it to be dbms_ijob calls, which lead me to suspect the SNP processes - alas, Win2k doesn't let you look at individual Oracle processes like UNIX does. Anyway, I can't find any mention anywhere that dormant SNP processes can be memory hogs. Am I missing something? For now I'll set Job_Queue_Processes to 0 and back to 4 right after the heavy work each night. Any init parameters I'm missing? ...other suggestions? Thanks. Jack Jack C.

RE: Manager decrees his data warehouse design. Help!
Rachel, That's what step #3 is for. Everyone will forget how bad the first warehouse was once the true properly designed warehouse is in place and delivering the goods. It sounds like there is pressure to deliver something right away - as usual, no time to design it properly. A manager I used to work for had the best philosophy: Lets hurry up and do it wrong so that we can fix it later. Sounds strange, but that's the business we choose to be in (ala The Godfather). *Nobody* wants to spend time and resources doing research to desig n a system. In a way, it's our (the IT industry's) fault. We have promised for years that we can develop programs faster and faster. Now, the managers expect it. But most of them realize that it's a mistake, but easier to fix after the fact. my little 2 cents.

What about statements issued in SQL*Plus or through JDBC etc.? v$open_cursor displays ALL the cursors for a given session, not justthe explicite PL/SQL or PRO*C stuff.A cursor is needed for EVERY SQL STATEMENT. The only cursor not displayed by v$open_cursor is the DBA himself/herself, especially if he has to support tools that do their own multiplexing, like Forte. c) The results from v$open_cursor is equivalent to the currently running transaction, right? So when are those entries removed again? When the transaction commits or when the sessions ends? Or when issuing a PL/SQL "close cursor". Or are those entries overwritten? by whom? when? An implicit cursor is closed when another statement is opened and re-parsed. If you take a look at v$session, you'll find that iscontainsthe "current SQL" address. That is, basically, the open cursor that the session is currently executing. When the next SQL comes in, this cursor will be closed, SQL put in the library cache and a new cursor will be allocated. d) what does querying "select * from v$sql_cursor" return? That query will usually return enough information for your screen to join it's ancestors and will leave you wandering why is that SQL*Plus does not have "clear" or "cls" command. Any ideas? Yes.

Re: MS Access migration to oracle
If VB code was connecting to Access db through ODBC datasource, just modify this this datasource (or delete/create new one with the same name) to use Oracle ODBC driver (instead of ACCESS ODBC driver) and point them to the entry in tnsnames, which you create for them to use. Still, probably they will have to make some modifications in their code, when connecting to the db, to provide logon/password information. I don't think it's possible to specify password, when configuring ODBC datasource. Igor Neyman, OCP DBA [EMAIL PROTECTED] - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, February 28, 2002 8:13 AM I've been told to migrate one MS-Access 97 database to oracle.

The people that were using this Access database were doing so by means of an ancient VB piece of ... code and they don't want or they don't know to adjust it. They expect the program to somehow find the new Oracle 8.1.7.3 instance and continue to work as it did before.

Re: Perf Advice Needed: cache buffers chains, high waits, _db_block_hash_buckets
[Mogens Nørgaard] Amen. Contention for cache buffers chains means too much logical IO, ie. find and exterminate heavy SQL. I don't see why the heavy SQL would result in the chain having 66 buffer heads in it, though, or why the sleep count would be so skewed. And my core question is still whether the number of buckets being non-prime is normal or not - it seems awfully wrong to me. That there's a lot of contention *is* a factor of the SQL, but the fact that it's so skewed to only a few chains is what worries me more. Once I have the contention down to a particular latch, but that latch protects a buffer chain with 66 buffer heads in it, how can I find out which ones of the 66 are generating the most attempts at that latch? Tell ya what - can I get a few ppl to run this query? It tells the min/max/avg for the number of buffers associated with each chain and if my numbers are high I can at least have a chance of spreading out the buffers over more chains (by upping the number of latches from 4k to 16k, 32, whatever) - it won't drop the actual IO any, of course, but since I don't have a hard fix on which buffers of the 66 are really the source of my contention, I'm not sure where to go from here. SELECT min(buffers_per), max(buffers_per), avg(buffers_per), sum(buffers_per) FROM ( SELECT count(*) buffers_per, hladdr FROM x$bh b, all_objects o, v$latch_children v WHERE b.HLADDR=v.addr AND b.obj=o.object_id AND v.name LIKE '%cache buffers %' GROUP BY hladdr ) My results: min = 39 max = 119 avg = 55.06 sum = 22 If this shows to be about the same in other (well-tuned) Oracle DB's, then I won't worry as much about the number of buffers in each chain and would then focus on trying to isolate the specific buffers, then the source SQL causing the problem, etc. Given my previous sql trace analyses, I have a good idea what the problem SQL statement is, but it's a bit of a necessary evil right now (a join of a table (260k rows) and a materialized view (2k rows), 6 conditions in there where, and it gets executed a ton, probably on the order of 10x a second at peak) - all indexes that helped performance are created and around already. :( But, ideally I'd like to be able to prove this is the cause of the hot buffers before fixing anything.

Re: Oracle on Sun StorEdge T3 Disk Array
Kevin - Not to smash your day, but we have had a horrible time with an older version of this array. The main drawback is that the arrays support a grand total of 2 LUNS each. We are actually looking a SAN solution now to replace our 2 T3 arrays. If you have a newer model of the T3s that support more LUNS, you should have much better luck. Part of our problem may be the fact that damagement was promised fantastic throughput on these devices, yet everything was configured as RAID-5 - for my database. When we went back and split up the arrays with 2 mirrored drives and the rest on RAID-5, we got a significant improvement. However, our SA was forced to destroy everything to do the re-configuration. We've also been hampered by the fact we are not running Veritas File System - just Volume Manager. YMMV - I hope.

RE: MS Access migration to oracle
Check the ODBC configuration in Control Panel and make sure the connection is not set to read only. If you have primary keys on the tables access should be capable of seeing these and thus will allow updates to the table. If not you should be prompted to supply the key columns from a list of columns when you attach to the table. Other than that I would suggest you update the ODBC drivers. - Ethan -Original Message- Sent: Thursday, February 28, 2002 7:13 AM To: Multiple recipients of list ORACLE-L I've been told to migrate one MS-Access 97 database to oracle. Oracle Migration Workbench did the trick in an extremely clean, quick and complete way. Tables are created, populated with data and it is now when the problem starts. The people that were using this Access database were doing so by means of an ancient VB piece of ... code and they don't want or they don't know to adjust it. They expect the program to somehow find the new Oracle 8.1.7.3 instance and continue to work as it did before. I created a new access database containing ODBC links to the Oracle tables, but the program is complaining that the links are read only.

Contention for cache buffers chains means too much logical IO, ie. find and exterminate heavy SQL. I don't see why the heavy SQL would result in the chain having 66 buffer heads in it, though, or why the sleep count would be so skewed. And my core question is still whether the number of buckets being non-prime is normal or not - it seems awfully wrong to me. That there's a lot of contention *is* a factor of the SQL, but the fact that it's so skewed to only a few chains is what worries me more. Once I have the contention down to a particular latch, but that latch protects a buffer chain with 66 buffer heads in it, how can I find out which ones of the 66 are generating the most attempts at that latch? Tell ya what - can I get a few ppl to run this query? It tells the min/max/avg for the number of buffers associated with each chain and if my numbers are high I can at least have a chance of spreading out the buffers over more chains (by upping the number of latches from 4k to 16k, 32, whatever) - it won't drop the actual IO any, of course, but since I don't have a hard fix on which buffers of the 66 are really the source of my contention, I'm not sure where to go from here. SELECT min(buffers_per), max(buffers_per), avg(buffers_per), sum(buffers_per) FROM ( SELECT count(*) buffers_per, hladdr FROM x$bh b, all_objects o, v$latch_children v WHERE b.HLADDR=v.addr AND b.obj=o.object_id AND v.name LIKE '%cache buffers %' GROUP BY hladdr ) My results: min = 39 max = 119 avg = 55.06 sum = 22 If this shows to be about the same in other (well-tuned) Oracle DB's, then I won't worry as much about the number of buffers in each chain and would then focus on trying to isolate the specific buffers, then the source SQL causing the problem, etc. Given my previous sql trace analyses, I have a good idea what the problem SQL statement is, but it's a bit of a necessary evil right now (a join of a table (260k rows) and a materialized view (2k rows), 6 conditions in there where, and it gets executed a ton, probably on the order of 10x a second at peak) - all indexes that helped performance are created and around already. :( But, ideally I'd like to be able to prove this is the cause of the hot buffers before fixing anything.

RE: Clash of the DBs in eWeek
At first glance it looks like they could have done more to tune Oracle. Certain tables could have been cached (or buffer pools could have been used). They're only using a 4K db block so it would have been nice to see tests with 8K and 16K db blocks. Sort area size may need tuning. I'd like to see some tkprof on the queries and see what the most expensive queries are in terms of CPU, I/O, and number of executions. It would be nice to see database results on Linux...

RE: moving from unix to NT
I don't have any experience with UTL_FILE on NT. I've used it a little on unix. Don't know why it wouldn't work on NT. As stated by others, it might be a problem if writing to network drives, as the SYSTEM user does not have access to those when run as a service. This doesn't seem reasonable though, as the instance itself does not run as a service. The VOS runs as a service, but not the instance. Best bet is to try it. The biggest problem will likely be your code. If you have paths hard coded in it, you will have to rewrite. If they are stored in a table, just change the data.

OPEN_CURSORS and SHARED_POOL_SIZE
SysAdmin of production system has increased shared_pool_size from 20MByte to 110Mbyte to correct a shared pool size error. Shortly after, he began seeing too many open cursors while trying to login via the front-end (Silverstream). RTFM says To take advantage of additional memory available for shared SQL areas, you may also need to increase the number of cursors permitted for a session. You can do this by increasing the value of the initialization parameter OPEN_CURSORS.

RE: ORA-00600 errors
The itar creation process now includes a utility where you can either lookup Ora-600 messages or have it examine the stack trace from an ORA-7445 dump. I had it analyze a stack trace this morning. The result of using the utility is a list of links to articles Metalink considers germane to the problem. None, however, seem to match my particular problem. I also found that I had to use another web window to actually bring up the listed documents via Metalink's advanced search facility using the document id, or through the bug query screen.

RE: Clash of the DBs in eWeek
They used weblogic for the webserver. Typically it will keep several connections open, pooling them in essence. The article indicated that *they* did all the Oracle tuning, and that Oracle did not send anyone to help with the tuning process (unlike MySQL), so it's probably amazing that they got the results they did. I don't think they lied, but I don't think they probably realized that they could have possible eeked out some additional performance had they worked it a bit harder with a knowledgeable web DBA.

Re: Unused users for the last 30 and 60 days.
Hi Deepender, I know of know builtin oracle view that will tell you this infomation. At a former job we were required to disable accounts that had not been used in the last 60 days. It has been a little while since I worked there (7 years to be exact) but basically this is what we did 1. created a tablecalled dbs_user_info with the fields (username, create_date, last_login_date) 2. copied the username and create field from dba_users into the fields, initially we set last_login_date to be = create; 3. Turned on auditing in the init.ora and audited successful logins 4. at night we went through the sys.aud$ table and for each user that existed updated the last_login_date truncating sys.aud$ when done 5. weekly ran a batch job that found all users that last_login_date was 30 days Beginning in 8i it might be easier to do this with an after login trigger rather than auditing Hope this helps, John that contained the username, [EMAIL PROTECTED] wrote: Hi All, I want to have report of all the users who has not used their Oracle username for the last 30 and 60 days.

Re: moving from unix to NT
Jared, On NT oracle.exe runs as OracleServiceSID service. Hence UTL_FILE will be executed under whatever OS account OracleServiceSID service runs. And I was not able to make it running properly under any other than SYSTEM account. Remember, on NT Oracle is one big (though multithreaded) process, unlike it is on UNIX. Igor Neyman, OCP DBA [EMAIL PROTECTED] - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, February 28, 2002 1:03 PM I don't have any experience with UTL_FILE on NT. I've used it a little on unix. Don't know why it wouldn't work on NT. As stated by others, it might be a problem if writing to network drives, as the SYSTEM user does not have access to those when run as a service. This doesn't seem reasonable though, as the instance itself does not run as a service. The VOS runs as a service, but not the instance. Best bet is to try it. The biggest problem will likely be your code. If you have paths hard coded in it, you will have to rewrite. If they are stored in a table, just change the data.

If so, myself and others on this list can point you in the right direction, as basics in Perl/Oracle/DBI are really not too hard.

I know nothing about Perl so would be interested in how to replace the use of UTL_FILE in PL/SQL with Perl. We use UTL_FILE quite a lot for reading and writing flat files. 2. With regard to external procedures, On Unix we currently use this to call a C routine that calls the system command to run Unix commands and scripts(Korn Shell). I presume we will need to amend these commands to their NT equivalents(or can I call Windows API directly from PL/SQL? on NT) and re-write the scripts...presumably in Perl?

Re: PocketDBA
I have. It is pretty cool. I believe the creator, Ari Kaplan, lurks on this list. I bet they'll send you a demo device if you ask.

RE: Unused users for the last 30 and 60 days.
You could audit connects and use that to determine which accounts have not connected to the database in the last 30-60 days. Connect auditing will have 0 performance impacts, but you will need to manage the audit table and write a good SQL script to give you the info you need. RF Robert G.

RE: Clash of the DBs in eWeek
On the MTS part, my faux pas. I saw the first dispatchers commented out along with the other mts% params. Also, on closer inspection, I was looking at create_nile2_database_details.htm in the C - Create Benchmark Database folder in the .zip file when I saw that processes was set to 150. Perhaps they made changes to the init.ora (from the B - Configure Database Server folder) after an initial GUI DB create? Thanks, Brian, and thanks all else that pointed out the JDBC connection pooling. I've been trying to take a look at that stuff, but I've got no time here at work and I can't run Oracle at home on my Linux/Alpha box. sigh Rich Jesse System/Database Administrator [EMAIL PROTECTED] Quad/Tech International, Sussex, WI USA -Original Message- Sent: Thursday, February 28, 2002 1:14 PM To: Multiple recipients of list ORACLE-L Which docs?
