    IMPORTANT: Do not interupt this patch session. Follow these
               instructions in a different session.

    1. As the APPLMGR user, login to the Application Tier (APPL_TOP) by
       sourcing the environment file.

    2. Locate the custom environment file:

       Note: the location of this file is determined by the value of the
             'Custom File location' (OA_VAR = s_custom_file) parameter
             in the Application Tier context file.  You can find out the
             value of this parameter through the AutoConfig section of
             Oracle Applications Manager (OAM).

       The file is typically called custom<SID>_<hostname>env and
       located in the $APPL_TOP directory.

       If the file does not already exist, create it.

    3. Find out the location of the XXAS Product Top:

       $ echo $APPL_TOP/xxas/1.0.1

    4. Add the following two lines anywhere in the custom environment
       file located in step 2:

       XXAS_TOP="<location of the XXAS Product Top from step 3>"
       export XXAS_TOP

       Save the file and exit.

    5. If this system has multiple Application Tier file systems, repeat
       steps 1-4 for each file system.
