CICS

  • 1.  cics liberty context root not found debug

    Posted Fri April 01, 2022 12:40 PM
    I'm a CICS newbie with lots of z/os background now responsible (cuz everyone else stepped back) for cics and a jvm app...

    I have two nearly identical, one application, JVMs on each of two systems (a test set and a prod set on two LPARs in a development plex...)

    I copied the environment from the unit test environment which was working to the other unit test environment, and the system test environment that was working to the other system test environment.

    For each environment, when I point to the url and port, i get the liberty screen, yay!

    When my customer attempts to use his app on the second / new copy, in test or model office, he gets context root not found.  I think this means he can't get to the application, and I'm having issues finding debug steps to take to resolve this.

    Is there anything in the community which gives one a process or usual suspects for this?

    Please advise...

    Hi Kevin. So it sounds like your Liberty server is up, but the application contained in it is probably not, and you'll need to consult the logs to work out why that would be.

    The most useful log for that is likely to be Liberty's messages.log file. This is typically located in <workdir>/<applid>/<jvmserver>/wlp/usr/servers/defaultServer/logs/messages.log, where <workdir> is set in your JVM server's profile. Look in there for messages that relate to this application. You'll be looking to see whether there was an attempt to start it, and what happened after that.

    We (in CICS) do have a troubleshooting page for Liberty JVM servers and web apps, though it tends to focus on the CICS-specific nuances - this may be a problem that is dealt with by Liberty's own troubleshooting information.
