Sam - what does
SHOW PARAMETER SESSIONS show? Just in case you have another line in your init.ora file. No, no that has never happened to me! Other than that, I haven't encountered the problem you describe.

We are running Oracle 7.3.4.5.0 on an IBM/AIX RISC System/6000: Version 2.3.4.0.0.
This afternoon, our users started getting the error message "ORA-00018: maximum number of sessions exceeded." As time went on, the number of sessions was decreasing (as shown by the count of rows in v$session). However, Oracle still did not allow connections. This lasted for about 40 minutes.
The sessions parameter in the initialization parameter file showed 300.
Querying v$session showed 246 rows.
Querying v$license reported:
SQL> select * from v$license;
SESSIONS_MAX SESSIONS_WARNING SESSIONS_CURRENT SESSIONS_HIGHWATER USERS_MAX
0 0 204 248 0
There seems to be a contradiction here: 300 sessions in init.ora; sessions_highwater at 248, and Oracle not allowing connections because the maximum has been reached.
Has anybody encountered this problem before. Is there a "simple" reason for this erratic behavior?
Management is looking for an answer as to why this has happened. Thanks for any input!
