# SCRIPT: AEM Offline TAR Compaction #
# AUTHOR: Shashi Yebbare #
# DATE: FEB, 09, 2019 #
# REV: 1.3.P #
# (For Alpha, Beta, Dev, Test and Production) #
# #
# PLATFORM: AIX, HP-UX, Linux, Solaris #
# #
# PURPOSE: To perform offline AEM compaction on Segmentstore #
# and reduce the size of the AEM repository, Script #
# uses a custom log-back XML configuration to log #
# additional compaction information. #
# #
# REVISED LIST: #
# DATE: FEB, 17 2019 #
# BY: Shashi Yebbare #
# MODIFICATION: Added custom log back XML configuration #
# #
# #
# set -n # Uncomment to check your syntax, without execution. #
# # NOTE: Do not forget to put the comment back in or #
# # the shell script will not execute! #
