If you run into following error in event log.
|
|
ORA-12520: TNS:listener could not find available handler for requested type of server
|
|
ORA-12519, TNS:no appropriate service handler found
|
|
You should:
|
|
I suggest that you read Metalink note 424566.995, which was posted by a user with a similar problem.ÿÿHe claims that
|
|
investigation showed that disconnections from Oracle were not being passed immediately to the listener.ÿÿThis caused the
|
|
listener to (incorrectly) think that Oracle had reached its session limit.ÿÿHe fixed the problem by increasing the value of
|
|
the "processes" startup parameter.ÿÿ(He says that increasing the value of the "sessions" parameter also worked.)ÿÿT
|
|
hat doesn't prevent the listener from having an incorrect count of sessions, but it does get around the ORA-12519 error
|
|
|
|
To do this:
|
|
1. Using TOAD connect to DB server with DBA user.
|
|
2. Run query ALTER SYSTEM SET PROCESSES = 500 SCOPE = SPFILE
|
|
3. Check that settings applies.
|
|
select * from v$parameter where upper(name) = 'PROCESSES'
|
|
4. Restart Oracle instance.
|
|
5. Use select * from v$session to view sessions
