Q

Maximum number of sessions exceeded

When I run a program through my application server, I get the following error: "ORA-00018:maximum number of sessions exceeded."

I have an application server (WebSphere) doing connection pooling with a max limit of 30 connections. My database is Oracle 9i. When I run a program through the application server, I get the following error: "ORA-00018:maximum number of sessions exceeded."

I am being very careful in closing all the PreparedStatements, CallableStatements, ResultSets and Connections in the program.

I will be very thankful if you can figure what the problem is.

The number of sessions has reached the limit defined by the SESSIONS parameter. This parameter is typically derived from the PROCESSES parameter. You will probably need to increase the number of processes, thus increasing the number of allowable sessions. The V$RESOURCE_LIMIT view can show you what the limit is and if you have reached it.
