Home -> Community -> Mailing Lists -> Oracle-L -> Wait Event "PX Deq: Execution Msg"
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?
Thanks,
Nancy
