Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server, Network Deployment edition,         *
    *                  version 8.5.5.                              *

    * PROBLEM DESCRIPTION: A port conflict may occur when          *
    *                      installing a second cell on the same    *
    *                      host machine.                           *
    ****************************************************************
    * RECOMMENDATION:  Apply a fixpack containing this APAR.       *
    ****************************************************************
    The code that checks for port conflicts looks at other cells
    on the system to generate a unique port number. Then it checks
    to see if the port number is unique within the current cell.
    If a conflict is found on the current cell, the port number is
    incremented and only checks the new port value against other
    values in the current cell. It did not check this new
    incremented value against any other cells on the host.
    

Problem conclusion

  • Code was modified to improve the port assignment process by
    checking the port number value against any other cells in the
    host machine, in addition to the current cell.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.10 Please refer to the Recommended Updates
