    ****************************************************************
    01.Security enhancement where JES Job Monitor binds to loopback
       address only. This change is incompatible with older RDz
       servers that expect JMON to bind to the default IP stack.
       By specifying LOOPBACK_ONLY=OFF in FEJJCNFG you can disable
       the new behavior, but this change is incompatible with
       current RDz servers that expect JMON to bind to the loopback
       address.
       As the loopback address has no TCP/IP stack affinity, support
       for _BPXK_SETIBMOPT_TRANSPORT has been removed.
    02.JMON argument validation rejects DSN+MEMBER > 44 characters.
    03.JMON stops reading spool dataset when a zero-length record
       is encountered due to incorrect I/O error processing.
    04.JMON port handling changed in v801. This enhancement lets the
       JMON IVP (fekfivpj) determine the host version, so that the
       same IVP can be used for all versions.
    

Problem conclusion

  • 01.Security enhancement where JES Job Monitor binds to loopback
       address only. This change is incompatible with older RDz
       servers that expect JMON to bind to the default IP stack.
       By specifying LOOPBACK_ONLY=OFF in FEJJCNFG you can disable
       the new behavior, but this change is incompatible with
       current RDz servers that expect JMON to bind to the loopback
       address.
       As the loopback address has no TCP/IP stack affinity, support
       for _BPXK_SETIBMOPT_TRANSPORT has been removed.
    02.JMON argument validation corrected to accept DSN+MEMBER <
       55 characters.
    03.JMON I/O error processing corrected.
    04.JMON port handling changed in v801. This enhancement lets the
       JMON IVP (fekfivpj) determine the host version, so that the
       same IVP can be used for all versions.
