ExternalConnectionPools

Workaround against fail-fast pools

When using an External Connection Pool TopLink depends on the external pool for all connection behaviour. If possible I would recommend checking your weblogic connection pool configuration to see if you can set the pool to make requesting threads wait for connections instead of throwing exceptions.

If this is not possible then you could write an exception handler, as you currently do for dropped and stale database connections, except all that is required is to re-execute the query (at which time TopLink will attempt to re-connect to the external pool). forum:281039

Such an exception handler is available here: ReconnectingExceptionHandler.
