# Shell skript to unpack an MQSeries Workflow hotfix package into a temporary
# directory and copy the updated files into the appropriate places.
#
# Valid for: MQSeries Workflow AIX v3.2.0 Hotfix 2
#            Filename of Hotfix: wf320aau.tar.gz
#
# Run this skript as 'root'
# Needs to be installed on top of MQWF 3.2.0 (= version 3.2.0.0)
#
# To check, use the command    lslpp -L "fmc*"
# A more detailed check can be done using the tool 'fmczchk', or
# by checking specific time stamps, like:
#   % what fmczutil
#   fmczutil:
#     MQSeries Workflow 3.2.0 Configuration Utility, Driver v32_663, Hotfix 1, Jul  8 1999, 10:50:24
#   (This is the correct base level version)
#
# All running MQSeries Workflow processes should have been stopped.
# Needs temporarily about 250 MB in the current file system.
# Needs "gzip" installed.
#
# Parameter: 1) Input file to be unpacked (must be .tar.gz)
#            2) (optional parameter) Existing backup directory,
#               where the original files can be copied into
# Note:      You need additional 250 MB free space in the backup directory
#
# Example:   fmchotfix wf320aau.tar.gz /tmp/WF320backup
