Does your app connect to the database using the listener or directly (BEQ) without specifying a connect string?

It should connect using the listener and a connect string.

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 =

"(ADDRESS=(PROTOCOL=TCP)(PORT=1521)(HOST=MYSERVER))" And was able to have only "shared" connections as opposed to "direct" connections

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
bob
