When I try to run this procedure from 2 sessions to insert 2M records performance degraded more.....This is the only user connected to database. -----Original Message----- From: ryan.gaffuri@xxxxxxxxxxx [mailto:ryan.gaffuri@xxxxxxxxxxx]=3D3D20 Sent: Wednesday, June 23, 2004 1:51 PM To: oracle-l@xxxxxxxxxxxxx Cc: Harvinder Singh; oracle-l@xxxxxxxxxxxxx Subject: RE: Performance question is that package run under concurrency or is it run serially? Is it run 30 times/second with one session, or are there multiple sessions accessing it?=3D3D20 if it is used concurrently, how many sessions are running it during your best performance and how many during your worst?=3D3D20 I am assuming that nothing else of consequence is occurring in the database at this time correct?=3D3D20 ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
