I failed to mention this is an 8.1.7.3 database. Sorry about that. Nancy -----Original Message----- McCormick Sent: Thursday, May 16, 2002 7:53 PM To: Multiple recipients of list ORACLE-L
Hello, I am hoping someone can help me with an elusive wait event called 'PX Deq: Execution Msg'. As you can see from the statspack "Top 5 Wait Events" this event accounts for almost 75% of the wait time. I have been looking in past Oracle-L posts, Google, Oracle FAQ, OTN, Metalink, Oracle manuals, etc. I can find almost nothing about this event. What I did find leads me to believe may be an idle event and that it is the second event 'PX Deq Credit: send blkd' that may be the more troublesome one. However I am still confused about both. Can someone help set me straight or tell me where there might be some more information about these 2 events?
