multiple userthreads per session
Posted in 2004
Topics: Versions, Editions & End-of-Life
We have noticed that since we have dropped and recreated some indexes over the
weekend, that we now see multiple userthtreads per session when we do an
onstat -u. Previously, we would see only one userthread per session. We are on
IDS 7.31.Here is a sample of the output:

What causes this?
Hi,
while this shows, that there are several user threads, it unfortunately
doesn't
show, what these threads are doing in detail.
You probably want to do the following onstat commands also:
"onstat -g ath", "onstat -g ses <session id>", "onstat -g sql <session
id>"
and possibly filter the output so as to get just that relevant for the one
session ...
That will give much better insight into what these are doing.
Regards,
Martin

What causes this?
Hi,
maybe your environment variable PDQPRIORITY was set to a value
greater than zero while you did "oninit" ?
