Home -> Community -> Mailing Lists -> Oracle-L -> RE: Unix Script --- Archive Log Destination Issue
I have found doing a "ps" command for your job name alone is just asking for a world of pain, and very very unreliable for reasons that I will not go into here. I like to create a lock file as the following ksh example illustrates:
JOB_LOCK="/tmp/${0##*/}"
if [ -f ${JOB_LOCK} ]
then
cat ${JOB_LOCK} | read v_LOCK_PID
echo "Found job lock pid ${v_LOCK_PID}"
if ps -ef | grep " ${v_LOCK_PID} " | grep -v grep | grep ${0##*/}
>/dev/null
then
echo "Job lock pid ${v_LOCK_PID} is running"
exit
fi
echo "Job lock pid ${v_LOCK_PID} not found, removing old job lock"
rm ${JOB_LOCK}
fi
v_LOCK_PID=${$}
echo "${v_LOCK_PID}" >${JOB_LOCK}
echo "Created job file lock"
. .the rest of your script goes here .
PS: I'm looking for a new TV, think you could get me a deal at BestBuy with your employee discount?

Hello All,
I have a script, which cleans up the archive log destination by moving the
old archive logs to a retention area based on the thresholds
1. Percent of space utilization
2. greater than 2 days old.
The script was working fine , except for the reason , sometimes we see multiple copies of the same. So I have added the following to code just to stop multiple copies. But now the script is not running at all and we did see more than 90% space utilization archive log destination.
Here is the added code:
##################################################### Exit If Already Running
####################################################function ExitIfAlreadyRunning
echo $(date)" Number Of Copies Running : $copies"
exit 0
else
return 0
fi
}
Any suggestions ???
I am not so good in using semaphores and all , looking for a simple solution if possible ..
Thanks in advance,
Madhu
