Concurrent users of system
Posted in 2000
Topics: General Discussion
Hello all.
I have to find out maximum number of concurrent users of Informix server.
I launched server on my computer with alone user - me.
Here's output of onstat -u :
Informix Dynamic Server 2000 Version 9.20.TC1 -- On-Line -- Up 00:01:17 -- 966
4 Kbytes
Userthreads
address flags sessid user tty wait tout locks nreads nwrites
c244018 ---P--D 1 informix - 0 0 0 21 5
c2445d4 ---P--F 0 informix - 0 0 0 0 2
c244b90 ---P--- 6 informix - 0 0 0 0 0
c24514c ---P--B 7 informix - 0 0 0 0 0
c245cc4 ---P--D 11 informix - 0 0 0 0 0
5 active, 128 total, 9 maximum concurrent
As I understand, processes with some letters in flags' 7th position, are system processes,
and doesn't count as users. Sessid 6 is without letter - that's me, 5 active processes at all.
What are those other 4 processes? Which configuration parameters I have to count out to find
the exact number of users from onstat -u?
Or maybe anybody has better idea of finding out number of concurrent users?
Thanks in advance!
D.

RTFM.
Administrator's guide give the values for them as follows
The flag codes for position 7:
B btree cleaner thread
C terminated user thread waiting for cleanup
D a daemon thread
F a page-cleaner thread
M special ON-Monitor (monitor) thread

OK, I've already read RTFM.
FM didn't give me answer : what are those 9 users, when output
shows only 5?

Which 4 processes? The 4 that you can't see out of "9 maximum concurrent" or the
4 apart from sessid 6?
