Linux Connector Messages 'NOT' in Opslog  (Lessons Learned)

  • 1.  Linux Connector Messages 'NOT' in Opslog  (Lessons Learned)

    Just a Knowledgeshare and Lesson Learned.

     

    When we put in the Linux Connector I put some automation in to alert if we get a flood of z/VM messages from servers.

    We wanted to know if a server was going nuts. It monitors the LXCONCOUNT.

     

    We recently had an issue where we were not getting any messages back from z/VM in the OPSLOG. We looked and the Linux Connector was running okay and it's log showed all the traffic / messages. We had some OPS/MVS automation fail because OPS/MVS did not get the messages from the Linux connector. We had no idea this was occurring until an alert was not issued and no Incident generated.

     

    So, to help us 'be in the know'

     

    I put some automation in place that will check the LXCONCOUNT periodically. (every 10 minutes)

    If the count does 'not' increment we will get an alert for us to investigate. The code will also issue the F OPSS,RESTART(LXC) to get try and get the Linux Connector and OPS/MVS talking again. Of course we alert for this as well.

     

     

    I also put in a message rule for 'OPS9500S'. If this occurs the rule will issue the 'F OPSS,RESTART(LXC)'

    Example: OPS9500S ABEND X'00C78000' in LXCON cell pool delete OPINLX+X'000042C4

    In the dump we got the 'Length Error' (see below). We are putting in the newer PTF 'RO93937' for this.
