Subject RE: Tomcat Startup Messages
Date Tue, 07 Feb 2006 08:48:03 GMT
Hello Warren,

actually I don't do more than invoking the tarball provided
catalina.sh script
where to my knowledge classpaths and similar env stuff is set
mainly in accordance
to a set JAVA_HOME.
I didn't touch catalina.sh, nor startup.sh.
I merely wrapped my own wee scriplet around that so that
heartbeat can start and stop 
the thing.
All the noise up to the case block in line 55 is just some weird
check for available resources.



$ cat -n /etc/ha.d/resource.d/catalina
      1 #!/bin/bash
      2 #
      3 # catalina - Heartbeat resource start/stop wrapper for
Catalina server
      4 #
      5 # should be placed in /etc/ha.d/resource.d/ and
distributed to failover node

This script is usually invoked by heartbeat (if not manually for
testing or maintenance).
Heartbeat passes it the -security switch as argument (along with
the implicit either start or stop)

$ grep catalina /etc/ha.d/haresources 
    catalina::-security
