zenjmx dependency?

I have restored a config from a CentOS VM to a RHEL VM and zenjmx will not start.

I am not strong in Linux, but from other threads (message/38562#38562) it looks like java was not installed on RHEL.

/opt/zenoss/ZenPacks/ZenPacks.zenoss.ZenJMX-3.3.1-py2.4.egg/ZenPacks/zenoss/ZenJMX/bin/java-functions.sh: line 55: exec: java: not found
2010-06-22 09:36:53,642 DEBUG zen.zenjmx: Queueing event {'severity': 3, 'component': 'zenjmx', 'agent': 'zenjmx', 'summary': 'zenjmxjava ended unexpectedly: A process has ended with a probable error condition: process ended with exit code 127.', 'manager': 'net-zen.net.ksu.edu', 'device': 'localhost', 'eventClass': '/Status/JMX', 'monitor': 'localhost'}
2010-06-22 09:36:53,657 DEBUG zen.zenjmx: Total of 1 queued events
20

[root@net-zen]# rpm -qa | grep java
[root@net-zen]#

Exactly what package is zenjmx looking for?

Thanks,

Re: zenjmx dependency?

John,

Thanks for the help. I've got the files but am not sure what directory Java should be installed to?

Re: zenjmx dependency?

Shaun,

Depending on what you downloaded, follow the applicable instructions in the link I provided in my previous response to assist you with installation.

On my RH box, java is located in /usr/java/ which follows the installation instructions as well. Once the install is done you can type java -version to verify it's installation. You may need to type these commands as well -

ln -s /usr/java/jdk1.6.0/bin/java /usr/bin/java

ln -s /usr/java/jdk1.6.0/bin/javac /usr/bin/javac

so that java can be run from from any directory.

Re: zenjmx dependency?

I am running a CentOS 5.4 base for Zenoss Core 3.0.1 (just upgraded from 2.5.1 - upgrade worked pretty slick). I did a 'yum install java' and it installed 3 packages:

java-1.6.0-openjdk
giflib
jpackage-utils

Prior to this I was getting this error:

/opt/zenoss/ZenPacks/ZenPacks.zenoss.ZenJMX-3.5.2-py2.6.egg/ZenPacks/zenoss/ZenJMX/zenjmx.py:195:processEnded
/opt/zenoss/lib/python/twisted/internet/defer.py:243:callback
/opt/zenoss/lib/python/twisted/internet/defer.py:312:_startRunCallbacks
--- <exception caught here> ---
/opt/zenoss/lib/python/twisted/internet/defer.py:328:_runCallbacks
/opt/zenoss/ZenPacks/ZenPacks.zenoss.ZenJMX-3.5.2-py2.6.egg/ZenPacks/zenoss/ZenJMX/zenjmx.py:377:_startJavaProc

Now the process starts with no errors and my zenjmx log looks like this:

2010-11-02 08:48:52,931 INFO zen.zenjmx: Connecting to localhost:8789
2010-11-02 08:48:52,962 INFO zen.zenjmx: Connected to ZenHub
