    Randomly generated workspace IDs are not unique if they are
    created within the same millisecond from different processes.
    

Problem conclusion

  • To prevent duplicated configuration Session or Workspace ID
    generation within the same millisecond from different
    processes, we implemented a new mechanism for the id
    generation. To use the new mechanism, a system properties
    called
    "com.ibm.websphere.management.configservice.sessionIdUniqueness"
    is needed to be set to "random" for each process that
    generates the configuration Session/Workspace id.
    
    The system property for server processes can be set either
    using wsadmin AdminTask.setJVMSystemProperties command or
    through the administrative console (see the following link).

    opic=/com.ibm.websphere.nd.multiplatform.doc/info/ae/ae/xrun_jvm
    .html
    
    After adding the property in,  please save the changes, also
    do sync node if this is a federated cell, and restart each
    server for it to take effect.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.21 and 8.0.0.2.  Please refer to the
