Hi,
I'm using RHEL5.5 in a Heartbeat/Pacemaker cluster managing Tomcat and Apache
HTTPD on two nodes using the ocf:heartbeat:tomcat resource agent for Tomcat.
Specific versions:
resource-agents 1.0.3-1
heartbeat-libs-3.0.3-1
heartbeat-3.0.3-1
pacemaker-1.0.8-1.0hg20100317.8debc1902e13
Tomcat 6.0.26 (downloaded from source).
I have modified the Tomcat resource agent to be capable of controlling multiple
Tomcat instances by exporting CATALINA_BASE as well as CATALINA_HOME - these
are the only changes I've made to the resource agent (this is why the agent
path is 'intact' instead of 'heartbeat' in the process list below) - diff
attached.
When manually issuing a restart of the clone resource on tomcat I'm left with a
dead 'start' process:
(before restart):
[r...@fmp-dun-tapp1 ~]# ps -efH | grep [t]omcat
root 22754 21037 0 10:09 pts/0 00:00:00 grep tomcat
root 5058 1 0 Jul07 ? 00:00:00 /bin/sh
/usr/lib/ocf/resource.d//intact/tomcat start
tomcat 5101 1 0 Jul07 ? 00:00:19 /usr/lib/jvm/java/bin/java
-Djava.util.logging.config.file=/home/tomcat/tc-1/conf/logging.properties
-Dname=tomcat -Djava.awt.headless=true -Djava.library.path=/usr/lib64
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xmx1024M
-Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath
/opt/tomcat/bin/bootstrap.jar -Dcatalina.base=/home/tomcat/tc-1
-Dcatalina.home=/opt/tomcat -Djava.io.tmpdir=/home/tomcat/tc-1/temp
org.apache.catalina.startup.Bootstrap start
(after restart):
[r...@fmp-dun-tapp1 ~]# ps -efH | grep [t]omcat
root 5058 1 0 Jul07 ? 00:00:00 /bin/sh
/usr/lib/ocf/resource.d//intact/tomcat start
root 2271 1 0 10:26 ? 00:00:00 /bin/sh
/usr/lib/ocf/resource.d//intact/tomcat start
tomcat 2307 1 21 10:26 ? 00:00:02 /usr/lib/jvm/java/bin/java
-Djava.util.logging.config.file=/home/tomcat/tc-1/conf/logging.properties
-Dname=tomcat -Djava.awt.headless=true -Djava.library.path=/usr/lib64
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xmx1024M
-Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath
/opt/tomcat/bin/bootstrap.jar -Dcatalina.base=/home/tomcat/tc-1
-Dcatalina.home=/opt/tomcat -Djava.io.tmpdir=/home/tomcat/tc-1/temp
org.apache.catalina.startup.Bootstrap start
Note the two 'tomcat start' processes above.
Each restart produces successively more copies of the 'tocmat start' process.
Does anyone know why this would occur? I thought the call to 'catalina.sh
start' which is backgrounded in
tomcat_start function in resource should exit after starting Tomcat - but
apparently it doesn't.
Any help / trouble-shooting tips appreciated.
Thanks,
Best Regards,
Brett
