Home -> Community -> Mailing Lists -> Oracle-L -> RE: PMON seems to not close sessions in a timely manner eg "Max
Mine is 8.1.7.2 on HP.
In init.ora, processes=1000 sessions=1000 mts_servers=8, mts_max_servers=20,
dispatcher=10
I have not seen maximum process reached but have seen "Deadlock: MTS Max Servers (20) reached" because applications had more than usual connections once in a while. But that's ok with the applications.

Well, I had placed the db is MTS mode and still hit the max processes(50)
#MTS_DISPATCHERS="(protocol=tcp)(dispatchers=5)(pool=on)(tick=1) (connections=1000)(sessions=4000)"
#MTS_MAX_DISPATCHERS=32 #MTS_SERVERS=5 #MTS_MAX_SERVERS=64 #MTS_SERVICE=MYDB #MTS_LISTENER_ADDRESS =
EG shows server=shared
select username, program, server from v$session
where audsid=userenv('sessionid');
I think Ive read all the docs I can find on multi threaded server but did not see anything about creating a service or adding a dispatcher, Im of the understanding that placing the above in my init.ora file, that creates the dispatcher when I bounce the db? In this case as far as I see my MTS service is MYDB.. Eg my SID
So, I must be missing something... I'd sincerely appreciate any suggestions ... Examples?? From all the docs I see this is all that's needed, obiviously not - Please advise
Thanks
