tcpstackname DETERMINED THAT OMPROUTE WAS NOT RESPONSIVE FOR AT LEAST timevalue SECONDS

Explanation

Sysplex problem detection has determined that OMPROUTE was not responsive.

tcpstackname is the name of the TCP/IP stack.

timevalue is the number of seconds OMPROUTE was not responsive. This value is determined by the GLOBALCONFIG SYSPLEXMONITOR timersecs parameter in the TCP/IP profile. See the z/OS Communications Server: IP Configuration Guide and the z/OS Communications Server: IP Configuration Reference for more information about the timersecs parameter and how it is used to detect OMPROUTE unresponsiveness.

System action

TCP/IP continues.
  • If the GLOBALCONFIG SYSPLEXMONITOR RECOVERY option is active and this stack is not the only member of its TCP/IP sysplex group, the following RECOVERY actions will occur:
    • This stack will leave the TCP/IP sysplex group.
    • This stack will no longer participate in sysplex distribution (as a distributor or target) or act as an owner or a backup for DVIPAs. All DVIPAs defined on this stack will be deactivated; however, the DVIPA definitions will be saved.
    • If the problem is corrected, this operator message will be deleted; if the GLOBALCONFIG SYSPLEXMONITOR AUTOREJOIN option is active, the stack will process the DVIPA definitions and rejoin the TCP/IP sysplex group.
  • If the GLOBALCONFIG SYSPLEXMONITOR NORECOVERY option is active, no action will be taken. If the problem is corrected, this operator message will be deleted.
  • If the operator did not stop OMPROUTE, TCP/IP sysplex problem detection will assume there is a problem with OMPROUTE and will issue an ABEND with system code 4C5, reason code TcpLostOMPROUTE ('0404'x) and capture an SVC dump of both the TCP/IP and the OMPROUTE address spaces.

See Sysplex problem detection and recovery in z/OS Communications Server: IP Configuration Guide for more information.

See GLOBALCONFIG statement in z/OS Communications Server: IP Configuration Reference for the definition of the SYSPLEXMONITOR parameters.

Operator response

If RECOVERY is active, and no 4C5 abend occurred, start the OMPROUTE procedure for this stack.

If OMPROUTE successfully starts, this operator message will be deleted.
  • If RECOVERY and NOAUTOREJOIN are active, then issue theVARY TCPIP,,SYSPLEX,JOINGROUP command to cause the DVIPA definitions to be processed, and the stack to rejoin the TCP/IP sysplex group.
  • If RECOVERY and AUTOREJOIN are active, no further actions are needed. The stack will process the DVIPA definitions and rejoin the TCP/IP sysplex group.
  • If NORECOVERY is active, no further actions are needed.

If an abend occurred, save this documentation and contact the system programmer.

System programmer response

If this message is displayed, but OMPROUTE is active, then it might not be getting enough CPU cycles to complete the task; OMPROUTE should run under the WLM service class SYSSTC (the default service class for started tasks). It might be necessary to run OMPROUTE as non-swappable. See the network design considerations with z/OS® Communications Server information in z/OS Communications Server: IP Configuration Guide for more information about improving OMPROUTE performance. If the OMPROUTE performance problem cannot be determined, contact the IBM® support center with any supporting ABEND documentation.
