- Attempts to access the Screens on SMS (Service Management System)  have failed.
- Attempts to connect to an SQL session was not successful.

The SQL session and java console show following error messages:

java.sql.SQLException: ORA-00018: maximum number of sessions exceeded

For more information about Java Console, please refer to Article 452853.1


Sometimes scripts open several SQL sessions to connect to the DB and retrieve certain data like :

- Monitoring System plugin (Example : Nagios in this case)

Those scripts are not closing their SQL sessions properly due to poorly written external scripts (non product scripts) or due to improper script ending (e.g. unexpected kill).
