J2CA0045E: Tolerating the connection errors during matchManagedConnection
Download Description
PH31288 resolves the following problem:
ERROR DESCRIPTION:
J2CA0045E: Connection not available while invoking method
createOrWaitForConnection for resource ...
Tolerating the connection error occurred event during the matchManagedConnention. The connection pool when processing the event is losing one or more managed connection during the error event.
LOCAL FIX:
Tuned the connection pool settings on unused timeout, Reap time and minimum connection.
Example:
PROBLEM SUMMARY:
USERS AFFECTED:
All users of IBM WebSphere Application Server using Commerce Container
PROBLEM DESCRIPTION:
J2CA0045E: Connection not available while invoking method createOrWaitForConnection for resource eis/JCAEmail
RECOMMENDATION:
None
While using resource eis/JCAMail, if connections are marked by the resource adapter as a bad connection in the matchManagedConnection code and the resource adapter uses connection error event in this method, connection can be
leaked resulting in J2CA0045E:

PROBLEM CONCLUSION:
The connection management code now handles the connection
error event if it occurs during ra.matchManagedConnection()
