Resolving errors reported by the lppchk command after installing WebSphere Application Server on AIX systems

If you install WebSphere Application Server on an AIX system, and issue the lppchk command, you receive errors for some of the installed files. These errors do not affect the installation, running and uninstallation of the product. To eliminate these errors, run the following script:

#
# Purpose:  This script should be run after the installation of WebSphere
#           Application Server 5.01.  This script will clean up all lppchk
#           errors related to the installation of WebSphere and IHS on the 
#           system.  There is no checking to see if lppchk may be reporting
#           a valid error for these products; all errors are cleaned up.
#
# Note:     This script must be executed as the root user.
#

then
   echo "$script: You must be root to run $script."

# Get the list of WebSphere products installed on the system with WAS 5.01
# so that each can be cleaned up.  Note that gskkm and mqm do not produce 
# lppchk errors so their filesets are not included in the list of filesets 
# to check.
#
# The output from the following command is of the form:
#

   # Each fileset part (USR, ROOT, SHARE) which has no files associated 
   # with it will have an entry ending in ":NONE".  If these are the 
   # only entries for a fileset then no further processing is required 
   # since there are no inventoried files associated with that fileset and, 
   # hence, no errors.
