2 table join taking 3hours - blah blah -roll on ibiza
I havent got original Subject e-mail as it is on my home PC. Firstly let me just say how I like to use this list. As I am completely different time zone to you guys i.e. I am Brit living in Middle East, also our weekends are thu/fri - by the time I read posted questions they are usually well answered. But I do like to follow the list and now and again I post a question for a number of reasons. In this case I am leaving for a months vacation to Ibiza on Wednesday, before that Im doing a database upgrade in test(on 10 schemas- each one takes 3-5 hours), a million other jobs and frankly Ive not faced a problem such as this for a long time. Now ,is not the time I have to investigate fully the problem myself, I have 2 more days and Im offsky to party,big style - aint gonna be worrying bout no sys.icol$ view. Anyhow I also have a work around as I explained by dropping a Maximo table (not from SYS schema if you look at original post carefully) but I still thought original problem may be interesting to some people out there or even another MAXIMO DBA who has had a similar experience.(we are a multi schema site- unique in Maximo world though). Many posts are unanswered and it was just a chance somebody would have a 'heads up' on this. If not no big deal. I must remind you that this a MANDATORY installation script provided by the vendor as part of the MAXIMO ERP implementation. All of a sudden a self proclaimed guru (MUPPET) starts accusing me of being a disgrace to DBA's then I get another mail also telling me how I should stop implementations of products if they touch SYS schema(whats all that IBM about - somebody please come to my rescue here). Is the world going mad or do I need this holiday more than I thought. (maybe I do) MAXIMO(MROI) is the leading vendor of MATERIALS MANAGEMENT software in the World (Its a USA company mate). Sorry BP/SHELL CEO we have to cancel 5 million dollar implementation because DBA says you cant create view in SYS schema(and its not Data Dictionary just cause its SYS ).Well SHELL/BP CEO says tell the DBA TO GO ** HIMSELF with his P45.Grow up please.Have you ever worked on a large ERP implementation. Have u ever been on a big job before? Well I took the abuse and then got accused of being to blase talking about SYS objects, and thats why I was rebuked (please- was that an apology ?). Well if you dont like the question or its not to ure liking the way I structured it well ignore it mate. Your reply was totally offensive ,rude,and also ignorant as you fully missed the point. By the way of course I tried wait events , your specialist subject must be ' the bleeding obvious'. I was looking for something a little more inspirational and imaginative. I know some people may find this reply also offensive and Im sorry for that, but enough is enough- I didnt realise there was a bizzy on the list and the rubuke did it for me. On a serious note though I am not afraid to ask questions and for that matter am not afraid to talk about sex (please feel free off line,girls only). Im also not afraid to take criticism, if I missed something obvious. Dont we all from time to time. IT people used to be fun and have a sense of humour. That includes laughing at yourself when you balls up. Next time I will take more care when structuring a question.Maybe I did rush it and it wasn't clear and was misleading. Anyhow I want to withdraw the original post, I cant deal with any other Numpty telling me woes and pitfalls and evil things that will happen to me if I mess with SYS. Roll on Ibiza - p.s. It was waiting all the time on TEMP tablespace- probably because Hash join. Temp was empty and well sized -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: 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: 2 small tables - Query takes 3 hours
This view is part of the upgrade script provided by the Vendor (duh): I've been DBA'ing for 7 years in DB2 and Oracle and messing around with a SYS view is obviously not done- .

2 small tables - Query takes 3 hours
Unix Solaris 8 and Oracle 8.1.7.4 As part of an upgrade to the Maximo application I run a join on 2 tables: select count(*) from sys.syskeys s, maxsysindexes m where s.ixname=m.name; sys.syskeys is 705 rows and maxsysindexes is 443 rows. when I trace the statement I find it doing a hash join and it estimates 434 blocks and it does each block in 30 secs. Prior to running the query I create the sys.syskeys view as detailed below: The only way I get round the problem is to recreate the maxsysindexes table: And of course query then takes 1 second. I have disabled hash join and the query just goes down another path taking just as long. Any thoughts as this only happened once the first upgrade in 10 schemas, now its happening all the time. --schema owner DROP VIEW SYS.SYSKEYS; CREATE VIEW SYS.SYSKEYS (IXCREATOR, IXNAME, COLNAME, COLNO, COLSEQ, ORDERING, FUNCTION) AS SELECT IO.NAME, IDX.NAME, C.NAME, C.COL#, IC.POS#, 'A', '' FROM SYS.COL$ C, SYS.OBJ$ IDX, SYS.OBJ$ BASE, SYS.ICOL$ IC, SYS.USER$ IO, SYS.USER$ BO WHERE IO.NAME = 'ADWEA' AND BASE.OBJ# = C.OBJ# AND IC.COL# = C.COL# AND IC.BO# = BASE.OBJ# AND IO.USER# = IDX.OWNER# AND BO.USER# = BASE.OWNER# AND IC.OBJ# = IDX.OBJ# AND (IDX.OWNER# = UID OR BASE.OWNER# = UID OR BASE.OBJ# IN ( SELECT OBJ# from sys.objauth$ where grantee# in ( select kzsrorol from x$kzsro ) ) ) ; -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: 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).

FEEDBACK: SMON taking 50% of CPU and certain queries hanging
It seems that the new version of Workflow that we implemented had a massive query running in the background, compound that with we run 9 companies (multi schema) in one database, that was 9 massive queries running in the background. The thing that I didnt notice it at first was that because SMON had all the CPU these processes showed very little CPU usage.Yet the following morning they had increased their CPU usage to about 5% each and SMON was normal. I easily identified the problem then , killed the queries, bollocked the vendor, and all is normal again. Anyhow thanks to the guys who contributed. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: 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).

SMON taking 50% of CPU and certain queries hanging
I recently upgraded a test server and found out today that it was hanging. SQLPLUS etc... I checked alert log and found following errors WARNING: aiowait timed out 1 times WARNING: aiowait timed out 2 times I shutdown and restarted and since then Ive noticed that only certain queries hang and the SMON process is running at 50% CPU. This Test service has been running for ages, allthough I did do an upgrade to the Application a week ago. Its the end of day so I will leave it running and see if SMON finishes.

RE: Hints being ignored
I'm on 8.1.6 and the other day I was trying to use a hint on the GL_INTERFACE table from Oracle Financials (i know OF is rule based)that I had copied to another database instance and I couldnt get a hint to work. And i know that Hint is not SQL supported and therefore the syntax has to be 100% correct. I was busy so I jut deleted records I didnt need but I will go back and try again later.

Re: RMAN Guru Needed - RMAN/Netbackup
Thanks for reply: I tried to restore the archivelogs on their own and it still asks for a backup piece thats on a tape that has been scratched. I looked at rc_backup_redolog and see lots of entries for the particular archive log.The last entry (in date order) points to a backup_set that is on the scratched tape. The second last entry points to a backup set that is on the tape that we have in the library. Im guessing that RMAN looks at the last entry and figures that this job backed it up and deleted it and therefore it is this tape. What I want to know is how I can get the archivelogs to be restored from the previous tape. Im probably going to raise a tar now. I can see in the logs that our bi weekly backup and delete all archivelogs ran on the 11/jan/2001 - yet these particular archive logs were backed up again the day after. Very strange behaviour yet could explain why RMAN is pointing to wrong tape. I always suspected RMAN was to easy to not be problematic Sam -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: 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: RMAN Guru Needed - RMAN/Netbackup
I am trying to alternate host to a point in time of 01-01-2002.
I restore current controlfile then run
run {
set until time "to_date('01-JAN-2002 03:00:01','DD-MON- HH24:MI:SS')";
allocate channel ch1 type 'sbt_tape';restore database;
recover database;
}
The netbackup log asks for a cold backup tape from 29-dec-01, restores that
data (if i resetlogs its is fine), then proceeds to ask for a group of
archivelogs and fails with failed to retrieve handle "al_6548_1_450965598'
Backup file not found.
When I look in the logs it is not asking for a tape like it did with the
first part(cold backup) and when i look at rc_backup_piece this handle is
pointing to a media that has been reused.
But we did a 2 weekly redo log backup on the 12-jab-02 and clear which went
to another tape that is still available. When i crosscheck
rc_backup_redolog I see that there are various tapes for that
sequence#(which i presume is the log file number), but how do we get rman
to look at the other tape ?
and why does it not ask for any tape in the logs when it wants the
archivelogs ? This whole process is very confusing and piss*** me off no
end. There's a pint for anyome who can help me here.
I'd be interested to know also how internally rman manages which tapes to
use for restore. In theory the same arcgive logs are on many different
tapes, so how does it decide which one to use ?
Im RTFM'ing as well
thanks
Sam

RMAN -Alternate Host next problem
Recall our Netbackup server holds only 2 months tapes and Im trying to
recover on an alternate host to the beginning of the year. I issue
following :
run {
allocate channel ch1 type 'sbt_tape';
restore controlfile;
alter database mount;
}
then once the current control files are back I issue
run {
set until time "to_date('01-JAN-2002 03:00:01','DD-MON- HH24:MI:SS')";
allocate channel ch1 type 'sbt_tape';restore database;
recover database;
}
The logs (thanks for location guys) ask for tape DC3787 which was has a
date last written 12/29/2001 22:29 netbackupsrv which I presume is the
last cold backup taken by rman, it then restores okay to that point.
RMAN-08023: channel ch1: restored backup piece 1
RMAN-08511: piece handle=bk_5942_1_449790981 tag=COLD_DB_BK_LEVEL0
params=NULL
RMAN-08024: channel ch1: restore complete
rman then seems to ask for correct archivelogs
RMAN-03022: compiling command: recover
RMAN-03022: compiling command: recover(1)
RMAN-03023: executing command: partial resync
RMAN-03022: compiling command: recover(2)
RMAN-03022: compiling command: recover(3)
RMAN-03023: executing command: recover(3)
RMAN-08054: starting media recovery
RMAN-03022: compiling command: recover(4)
RMAN-03023: executing command: recover(4)
RMAN-08017: channel ch1: starting archivelog restore to default destination
RMAN-08022: channel ch1: restoring archivelog
RMAN-08510: archivelog thread=1 sequence=17138
RMAN-08022: channel ch1: restoring archivelog
then i get errors 0ra-19511 backup up file not found.
So I can see RMAN seems to know the archivelog files it needs, yet they are
not on that tape,and the Netbackup log doesnt ask for the next tape.
Can I manually recover these archivelogs or am I doing something wrong? I
will be researching myself but if any of you guys can help it will be
great. Plus my weekend starts today.
thanks
Sam

RE: # of datafiles per tablespace
In a UNIX system it is better to have more small size datafiles than a few or one large datafile: The reason is that UNIX aquires an exclusive file write lock and therefore if you use multiple files you will avoid a situation where multiple simultaneous writes to data files become serialized and consequently reduce I/O performance: For example instead of one 2GB Data file , split it into 8 250mb: By the way I am addressing OLTP type systems with this e-mail -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: 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).

You can create a LOGON Trigger to stop users using anything i.e. SQLPLUS ,MSACCESS etc... I have applied one at our site and works good.
