The only change that I have made is the cursor_shareing_exact hint. There was nothing else done (to my knowledge) The explain plan did not seem to have changed thank you Gene Gurevich Oracle Engineering 224-405-4079 "ramick" <ramick@xxxxxxxxx om> To Sent by: <genegurevich@xxxxxxxxxxxxxxxxxxxxx oracle-l-bounce@f >, "'oracle-l'" reelists.org <oracle-l@xxxxxxxxxxxxx> cc 06/19/2006 04:46 Subject PM RE: cursor sharing Please respond to ramick@xxxxxxxxxx m Are you 100% sure it's due to cursor_sharing? Maybe you already checked, but is the execution plan the same? Is this 9204 on AIX? -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of genegurevich@xxxxxxxxxxxxxxxxxxxxx Sent: Monday, June 19, 2006 2:19 PM To: oracle-l Subject: cursor sharing Hi all: Can someone recommend a good article on the cursor sharing in Oracle 9. I just found a query that runs in 5 seconds with CURSOR_SHARING_EXACT and in more than 1 hour without it (cursor_sharing is set to force on the DB level) I'm trying to find out why it happens. thank you Gene Gurevich -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
