Home -> Community -> Mailing Lists -> Oracle-L -> parallel query waitevents
Hi.
I have a strange situation namely that a user process is waiting
on event PX Deq: Execute Reply. Besides this event I have 2
parallel query processes waiting PX qref latch and 2 processes
on PX Deq: Execution Msg
I have never enabled parallel query option and I checked
all parameters again and did not find any clue in those.
Any idea what might be causing this?
Regards,
Jeroen
