This section describes the known database driver issues and associated solutions.
After porting applications from another application server, physical connections are not being closed properly after the connections timing out. This problem is seen with the DB2 8.1.x version of the Client libraries (Type II) Driver against the same DB2 7.1.x Database Server.
Set the SteadyPoolSize and MaxPoolSize to the same number, and in addition, set the Idle Connection timeout also to 0 (zero). This disables the timing-out of idle connections and the user will have the full set of connections available.
