New server Process not allowed

[JOSBAS]

Hi,
I Have an oracle 8i DB running on a CompaqTrue64 Unix server.
When The concurrent sessions is equal to 41 sessions, a new session can't be created and i have the following errors:
TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12540: TNS:internal limit restriction exceeded
TNS-12560: TNSrotocol adapter error
TNS-00510: Internal limit restriction exceeded.

Our License is for 100 concurrent session.
I queried the V$License and I found that :
SESSIONS_MAX = 0 and USERS_MAX = 0.

How Can i resolve the problem to allow more concurrent sessions ?

Thanks.

Try looking at v$resource_limit to see what you are hitting.
