For detecting the server crash, you need some info from which to tell that, maybe from a log file generated by the JBoss server, you can setup a cron job to grep the log file regularly. After that, you can try to stop the JBoss server with its stop script, wait some time and then use ps -ef | grep my_jboss_server to check whether it's stopped, if it is not, you may want to directly kill the process(Caution, killing a JBoss process directly may cause some damage to your data, some lifecycle code may not be executed).
The following script is for reference:
Code:
crash_msg=$(grep -o "AN_ERROR_MSG_MEANS_CRASH" jboss_log_file)
if [[ $crash_msg != "" ]]; then
/var/opt/HP/ALM/jboss/bin/run.sh stop
sleep 5
ps -ef | awk '/my_jboss_server/{print $2}' | xargs kill -9 # change my_jboss_server to a relevant string in your environment
/var/opt/HP/ALM/jboss/bin/run.sh start
fi
Note: Try these commands at home before you use them on production environment.
