Error description

  • Transactions can fail when there are transactions already
    being processed on the server. Exceptions occur because the
    transaction IDs are not unique across multiple processes. The
    transactions share the same cell, node, and server name.
    
    The exception that occurs resembles the following exception:
    
    com.ibm.websphere.objectgrid.TransactionException: Warning:
    Server side transaction identifier not expected and found in
    session cache [incoming transaction request
    id:Local-42A6E141-9510-487E-E000-00000A2973AA] The
    client request may have timed out and retried.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of WebSphere eXtreme Scale who have   *
    *                  multiple profiles with the same cell, node, *
    *                  and server name.                            *
    ****************************************************************
    * PROBLEM DESCRIPTION: The identifier that is used for         *
    *                      representing a cell, node, and server   *
    *                      process erroneously takes precedence    *
    *                      over the process ID.                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The code was updated to correct the behavior so that the
    process ID is given the intended priority for helping to make
    the transaction ID unique.
