Error description

  • TCPIP SysplexMonitor Recovery issued message EZZ9674E indicating
    sysplex processing was not responsive.  TCPIP attempted to
    cleanup from this, but was unable to and issued message
    EZZ9675E.  A V TCPIP,,SYSPLEX,JOIN command was accepted with
    EZD1178I but did not join the sysplex.  In this case, since
    recovery did not complete successfully, TCPIP shoud have failed
    the command with message EZD1195I THE VARY
    TCPIP,,SYSPLEX,JOINGROUP COMMAND WAS REJECTED.  THE STACK MUST
    BE  RESTARTED TO JOIN A TCP/IP SYSPLEX GROUP.  Message EZZ9675E
    indicates TCPIP needs to be recycled.
    .
    .
    VERIFICATION STEPS:
    1) SysplexMonitor Recovery is coded.  Message
    EZZ9674E TCPIP SYSPLEX PROCESSING WAS NOT RESPONSIVE FOR AT
    LEAST       60 SECONDS
       is issued, followed by message
    EZZ9675E SYSPLEX PROBLEM DETECTION CLEANUP HAS FAILED FOR TCPIP
    2) A join command was issued and accepted:
    EZZ0060I PROCESSING COMMAND: VARY TCPIP,TCPIP,SYSPLEX,JOINGROUP
    EZD1178I THE VARY TCPIP,,SYSPLEX,JOINGROUP COMMAND WAS ACCEPTED
    3) A dump of TCPIP shows the XFPD_Partial_Cleanup bit is set
    

Local fix

  • None.  TCPIP must be recycled.
