APAR PQ45074 E-fix Documentation

Problem Description:

     WLM failover does not proceed correctly.

Cause:

     When the JNDI CosNaming plug-in is called to look up a context, a remote
     CORBA call on the returned context object is made in a effort to convert
     the object to its RMI stub object.  If a NO_RESPONSE exception is thrown
     from the call, the plug-in should catch the exception and simply return
     the unprocessed context object to the caller to allow WLM processing to
     continue.  Instead, the exception is not caught and is passed through to
     the caller.

How to apply fix: 

     You must replace a class file that resides in ujc.jar.  Listed below are
     the steps to update ujc.jar:

     1) Stop the Admin Server and all application servers.

     2) Save a copy of the original version of ujc.jar, which is found
        in the directory $WAS_HOME/lib, where $WAS_HOME is the WebSphere
        AppServer directory.

     3) Create a temporary directory, e.g., /tmp/PQ45074

     4) Copy PQ45074.jar to the temporary directory.

     5) Make the temporary directory your current directory.

     6) Extract the contents of PQ45074.jar into the temporary directory,
        e.g.,

        jar xvf PQ45074.jar

        Note:  If the jar command is not found in your PATH, you can
               add it to your PATH by running the WebSphere setupCmdLine
               utility as follows:

               UNIX: . $WAS_HOME/bin/setupCmdLine.sh
               WIN:    %WAS_HOME%\bin\setupCmdLine.bat

               where $WAS_HOME (%WAS_HOME%) is the WebSphere AppServer
               directory.

     7) Update ujc.jar with the class file extracted from PQ45074.jar, e.g.,

             jar uvf $WAS_HOME/lib/ujc.jar com/*

        where $WAS_HOME is the WebSphere AppServer directory.

     6) Restart the Admin Server and application servers.
