Problem conclusion

Temporary fix

Comments

  • This APAR adds support to CICS so you can, if you choose,
    specify a new WLP_INSTALL_DIR value in your JVM profile to use
    an alternative version of Liberty from the one that is supplied
    with CICS.
    
    The CICS Knowledge Center will be updated to document that the
    JVMSERVER JVM profile option WLP_INSTALL_DIR can now be used to
    specify the installation directory of an alternative Liberty
    version.  In such cases CICS will verify the level of Liberty
    by:
    - Enforcing a minimum version of Liberty. If you attempt to
    launch a version of Liberty below the minimum level supported by
    CICS, an exception is thrown and the Liberty JVM server does not
    start. The exception message - written to JVMLOG and STDERR -
    indicates the version of Liberty being launched and the minimum
    version accepted.
    - Issuing a warning if the version of Liberty being launched is
    greater than the maximum version of Liberty supported by CICS.
    The warning is written to JVMLOG and Liberty continues to
    launch. This might happen if CICS has not yet offered official
    support for this level of Liberty, or if you have not applied
    the companion CICS service APAR. If this is encountered, it is
    prudent to confine your use of such versions to test, prototype
    or development systems.
    
    The minimum and maximum supported Liberty versions will be
    reassessed regularly and changed when appropriate by the
    quarterly CICS Liberty fixpack APAR.  At present this
    functionality supports Liberty 20.0.0.9 following the closure
    of APAR PH28793.
