ORA-12602: TNS: Connection Pooling limit reached
Cause: The operation failed because maximum active current connections has been reached. It may not be a real error when the Connection Pooling feature is enabled. It is possible that the application later reissues the operation and successfully grabs the connection pool slot and proceeds.
Action: This is an internal error. Enable tracing and attempt to repeat the error. If it occurs again, contact Oracle Customer Support.
