I want the tomcat to restart when java goes 100% cpu utilize and remain on this , Get pid kill and start tomcat .
Code:
top | grep java
We can get pid and cpu utilize , But how can we do on run time.
If you already have the script to monitor CPU & restart ... add that script to crontab and run the script every minute or whatever frequency that suits you.
Does anyone have an example of a ksh script that executes a Sybase stored procedure, via the ISQL command, and can detect a deadlock and loop until the process completes successfully? I'm a little confused on where to start.
Thanks in advance for any assistance you can provide. (0 Replies)

I'm becoming a dying breed where I work. More and more sys admins are advocating automatically restarting failed services such as tomcat, jboss, etc. I've always been against doing this except with buggy apps that can't be fixed or avoided.
My main argument is that I feel it's a trick used by... (9 Replies)
