I received the following message our from database administrator regarding the ASAP SARM database.The following sentence is being reported at the oracle log: -----------------------------------------------------------------------------------------

Wed Apr 20 20:42:32 2005ORA-01555 caused by SQL statement below (Query Duration=96516 sec, SCN: 0x0000.4e3af49c): Wed Apr 20 20:42:32 2005 DELETE FROM TBL_SRQ_LOG WHERE SRQ_ID NOT IN (SELECT SRQ_ID FROM TBL_SRQ)


Since operation (as it is) takes a long time (27 hrs) and either one or another (or both) are changing too much (beyond our undo-retention of 3hrs) operation is bound to fail every time it runs. I have a suggestion to improve this operation. Change DELETE statement as:delete from TBL_SRQ_LOG a WHERE not exists (SELECT null FROM TBL_SRQ b where b.SRQ_ID = a.SRQ_ID)

I ran query below (ran in less than 30 seconds) and looks like there only are 441 records out of 2754908 to delete. 1 select count(*) FROM TBL_SRQ_LOG a 2* WHERE not exists (SELECT null FROM TBL_SRQ b where b.SRQ_ID = a.SRQ_ID)SQL> / COUNT(*)


Causes a cron job to fail, query is taking too long to execute, impacting other part of ASAP processing.
