    ****************************************************************
    In a Remote Hot Standby configuration, after a complete
    back up Controller take over scenario, when the primary
    Controller is resumed, TCP/IP errors occur with message
    EQQIP03E, until the Controller is recycled.
    Moreover two problems have been fixed concerning the
    parsing of initial parameters with this feature enabled,
    including the TCP/IP options and the USRMEM for z-centric
    feature, and an issue of XCF workstations remaining in
    "Waiting for connection" status at start up.
    

Problem conclusion

  • All problems have been fixed and the now the processing
    is correct.
