Script for deleting and checking core files on SAP Solaris hosts

Posted on


The situation of the file system full for /usr/sap is frequently met. Probably that the first thing that any admin would do is to check if he can cleanup any core files on the FS.
In order to have an overview and also to avoid this manual check/cleanup, I created a script to check the existence, time stamp and size of such file and send this information via email.
Also if the file is older than seven days this will be deleted, having enough time to analyze the cause for the generation of the file.
Here is how the script looks like:

#!/usr/bin/ksh
cd /usr/sap/SID/DVEBMGS*/work
FILE1=$(ls -l core |grep -v grep | grep -cw core)
FILE2=$(find . -name core -mtime +7 | grep -v grep | grep -cw core)
if [ $FILE1 != 0 ]
then
echo "There is : $(ls -l | grep -cw core) core
with the name : $(ls -l core)
and size : $(du -h core)
space left on FS :
$(df -h core)
$(hostname), $(date)" |
/usr/lib/sendmail -v email@domain.com
else echo "no core - do nothing"
fi
if [ $FILE2 != 0 ]
then
(rm core) && (echo "A core file older than one week has been deleted on $(hostname), $(date)" : [$(ls -l core)]) |
/usr/lib/sendmail -v email@domain.com
else echo "no core older than one week"
fi

This is how such an email should look like, if any cores are found:

There is : 1 core 
with the name : -rw-------   1 sidadm   sapsys   90001069 Mar 19 16:12 core
and size :   86M	core
space left on FS :
Filesystem             size   used  avail capacity  Mounted on
hostname:/usr/sap   1.0G   175M   849M    18%    /home/sidadm
hostname, Thu Mar 24 10:10:00 CET 2017
