Title: Queue_message wait event

Hi all,

Does anyone know how to tackle this one? Developers are complaining that (it appears) the de-queuing is slow.

  • DB is 9202
  • aq_tm_processes = 5
  • job_queue_processes = 4
  • _job_queue_interval = 3

SQL>  select * from gv$aq where qid in (44673,42358);

       QID    WAITING      READY    EXPIRED TOTAL_WAIT AVERAGE_WAIT
---------- ---------- ---------- ---------- ---------- ------------
     42358          0          1          0          0            0
     44673          0         11          0       1321   146.777778

The average_wait column ... is it micro|centi|mega seconds??
Also how to investigate the de-queuing problems? I couldn't find a single hit on queue_message event on metalink, even an advance search.

Thanks in advance for your help
Raj
