Starting the agent w/ only RHQ_AGENT_JAVA_HOME set does not work
Last modified: 2013-09-02 03:24:50 EDT
Description of problem:
Starting a jon2.3 rhq 1.3 agent w/ only RHQ_AGENT_JAVA_HOME set to the jdk path does not work
get an error:
[root@10-16-120-123 bin]# ./rhq-agent.sh
There is no JVM available.
Please set RHQ_AGENT_JAVA_HOME or RHQ_AGENT_JAVA_EXE_FILE_PATH appropriately.
after setting RHQ_AGENT_JAVA_EXE_FILE_PATH the agent will now start.
Basically the language in the error should be changed to:
Please set RHQ_AGENT_JAVA_EXE_FILE_PATH appropriately.
Temporarily adding the keyword "SubBug" so we can be sure we have accounted for all the bugs.
new = Tracking + FutureFeature + SubBug
making sure we're not missing any bugs in rhq_triage
So the workaround is:
"after setting RHQ_AGENT_JAVA_EXE_FILE_PATH the agent will now start."
But I really think the bug is get it so that you only need to set RHQ_AGENT_JAVA_HOME to have the agent work.
This is working for me:
$ env | grep JAVA_HOME
$ ./rhq-agent.sh --nostart
RHQ 3.0.0-SNAPSHOT [2413b00] (Mon May 24 15:37:10 GMT-05:00 2010)
Agent no longer accepting input at prompt.
The agent will wait for  threads to die
Shutdown complete - agent will now exit.
When you try this again, export the RHQ_AGENT_DEBUG variable, setting it to true ("export RHQ_AGENT_DEBUG=true"). When you start rhq-agent.sh, it will dump alot of debug messages to stdout, including variables it uses to start (like RHQ_AGENT_JAVA_HOME) and the command line it tries when attempting to start the agent. This might help debug your problem. I don't think its a bug, I think it is probably a problem in the user environment.
Verified on JON 2.4 GA
1) Installed JON Server
2) On agent box only set 'RHQ_AGENT_JAVA_HOME' (make sure that there is neither set 'RHQ_AGENT_JAVA_EXE_FILE_PATH' nor 'JAVA_HOME')
3) Install RHQ-Agent
RHQ-Agent successfully installed with environment variable 'RHQ_AGENT_JAVA_HOME'.
