Hello everyone. I am trying to run a 2 node cluster with 1 shared IP for Tomcat. This works fine until I set the monitor operation inside the Tomcat resource where the CRM keeps trying to restart Tomcat over and over infinitely.
Without the monitor operation in the CIB it won't keep trying to restart
Tomcat but if I stop it manually it doesn't automatically get started
again.
I tried the tomcat OCF RA but there are lots of incorrect values hard
coded in so I edited up an init script to what I thought was LSB
compatible. This is the init script:
#!/bin/sh
# description: Start or stop the Tomcat server
#
### BEGIN INIT INFO
# Provides: tomcat
# Required-Start: $network $syslog
# Required-Stop: $network
# Default-Start: 3
# Default-Stop: 0
# Description: Start or stop the Tomcat server
### END INIT INFO
RETVAL=$?
NAME=tomcat
export JRE_HOME=/opt/java
export CATALINA_HOME=/opt/$NAME
export CATALINA_BASE=/opt/$NAME
export JAVA_HOME=/opt/java
check_running() {
NAME=$1
LINES=`ps -ef | grep java | grep opt | grep $NAME | grep -v grep | wc
-l `
[ $LINES -gt 0 ] && echo "yes"
}
case "$1" in
'start')
RUNNING=`check_running $NAME`
[ "$RUNNING" ] && exit 0
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
$CATALINA_HOME/bin/startup.sh
fi
;;
'stop')
RUNNING=`check_running $NAME`
[ ! "$RUNNING" ] && exit 0
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
$CATALINA_HOME/bin/shutdown.sh
fi
;;
'restart')
$0 stop
sleep 15
$0 start
;;
'status')
RUNNING=`check_running $NAME`
[ "$RUNNING" ] && exit 0 || exit 1;;
*)
echo
echo $"Usage: $0 {start|stop}"
echo
exit 1;;
esac
exit $RETVAL

This is what crm_mon says:

It was working but suddenly stopped and I have no idea why. If anyone could
provide any pointers that would be great. I'm using:
SLES 10 SP2
Heartbeat 2.1.3
Thanks
