    2. MOM hangs and no data is displayed in the Workstation after upgrade when SOA is used. TEC596462




    MOM hangs and no data is shown in the Workstation after upgrade.

    In the MOM log, the ClusterManagerAsyncExecutor thread is waiting for a reply from one of the collectors for an executeAsyncTreeQuery. This method waits for a response by blocking on the response method until a time out occurs. This indicates that one of the Collectors is not responding to a query request from the MOM. SOA threads are known to occasionally exhibit this problem.

    3. Configure APM to connect to Oracle with Enterprise User Security (EUS). How to resolve the error: java.sql.SQLException: unsupported verifier type
