Well,
at least I have discovered what status await_MC%d in onstat -g con (or
onstat -g wai) of thread means:"Producer thread(s) are waiting to coordinate their status with their
Master Consumer thread."
We have huge amout of scan threads with this status which increases
continuously.
May I kindly ask for some comment?
Thanks

we have an java application running on websphere 5 and using jdbc
connection pooling accessing data in IDS 9.40.FC3 on AIX 5.2,
pdqpriority=1
<br>
<br>
there is 20 connections-user session used by appserver and reused

however, the number of associated threads increases from day to day,
currently more than 3000
<br>
it seems every session holds its threads even not used anymore

<br>
onstat -g ath looks like, e.g.:
<br>98365 7000000a8df0e00 7000000ae4537a0 2 cond wait await_MC34
4cpu scan_34.0
<br>
which means scan threads waiting for condition await_MC34
<br>
onstat -g con shows, e.g.
<br>4787 7000000ac345418 await_MC34 98372 86898
<br>
<br>
what are these threads waiting for?
<br>
how to release them?
<br>
why it is not release automatically?
<br>
what is await_MC??

thank you
