7.13.2. Setting a Java Option
Editing the
agent-configuration.xml file only sets the node name; the node location still has to be passed every time the agent is started.
By setting a Java option in the
rhq-agent-env.sh file, the Java preferences node information is set once and then persisted, so you can restart the agent as a service, without having to pass --prefs options or edit and reload the configuration.
- Open the agent prompt. For example, if the agent process is already running, the prompt can be opened by re-running the
rhq-agent.shscript with the-noption.agentRoot/rhq-agent/bin/rhq-agent.sh -n
[rhquser@server ~]$ agentRoot/rhq-agent/bin/rhq-agent.sh -nCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Use the
setconfigcommand to set theRHQ_AGENT_ADDITIONAL_JAVA_OPTSvalue with the preference node. For example:> setconfig RHQ_AGENT_ADDITIONAL_JAVA_OPTS="-Djava.util.prefs.userRoot=agentUserHomeDir/.java/.userPrefs/rhq-agent/agent01-node"
> setconfig RHQ_AGENT_ADDITIONAL_JAVA_OPTS="-Djava.util.prefs.userRoot=agentUserHomeDir/.java/.userPrefs/rhq-agent/agent01-node"Copy to Clipboard Copied! Toggle word wrap Toggle overflow The preference node can be in the user preferences directory with a different name, such asagent01-node, or it can be in an entirely different location, such as/etc/agent-preferences, which is not a shared or filesystem-mounted location. - Restart the agent process to load the new configuration. For example, if the agent is running as a service:
service rhq-agent-wrapper.sh stop service rhq-agent-wrapper.sh start
[rhquser@server ~]$ service rhq-agent-wrapper.sh stop [rhquser@server ~]$ service rhq-agent-wrapper.sh startCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Note
It is also possible to stop the agent, edit the
rhq-agent-env.sh file directly, and then restart the agent.
Important
Do not set the Java option within the rhq-agent runtime directory because this file is overwritten during JBoss ON agent updates. The default location for the rhq-agent runtime is
$USERHOME/.java/.userPrefs/rhq-agent/default.
