# Purpose:    Purge OMS logs files older than x number of days on an EM10g installation.        #
#                                                                                               # 
#             NOTE: Restart of the OMS required! ...not ideal, but did the job at the time :)   #
#                                                                                               #
# Typical cron entry (midnight, every Sunday):                                                  #
