Any news on this topic? I found no documentation about this feature and JCA compatibility. anonymous wrote : NS in turn propagates these failure events to JDBC layer in | OracleAS 10g and the JDBC layer transparently cleans up the existing stale | connection pool to the failed RAC node and creates another connection pool to | live RAC node. I made some test on plain JDBC without OracleAS... Actually when the node fails, a specific exception is propagated to the jdbc driver and then the application. Oracle states that, in this case a rollback shall not be issued because the driver has already rolled back the transaction. I don't know if the javax.resource.spi.ConnectionEventListener.errorOccured(ConnectionEvent) is called inside the JCA.
