Team:
Happy New Year!!!!
I am attaching two scripts. These Scripts are supposed
to trim cron log file (/var/adm/cron/log) and oracle
listener log
(/opt/oracle/817/network/log/list817.log), both log
files are getting trimmed properly ,but I found that,
there is no log entries for both cron log and listner
log files after deploying these 2 scripts. Oracle cron
jobs are working properly. I am missing something in
the scripts. Please Help.
Thanks
Brian.
