Want to enable classloader logging on 10.1.3

523087Jul 26 2006 — edited Jul 28 2006
Hello,

To troubleshoot some classloader problems I would like to activate logging for OC4J running within a 10.1.3 OAS. According to the documentation[1], to activate logging:

"In an Oracle Application Server configuration, system properties are set in the <data> element where the id attribute is "java-options" in the opmn.xml file for the OC4J instance."

But I am unsure which opmn.xml file the documentation is referring to:

C:\10.1.3\OracleAS_1\j2ee\oc4j_opmn.xml
or
C:\10.1.3\OracleAS_1\opmn\conf\opmn.xml

The former appears to be a subset of the latter--which one do I need to alter and why are there two files?

Thanks,
Glen

Got logging activated. It was the C:\10.1.3\OracleAS_1\opmn\conf\opmn.xml file that needed to be updated.

To activate logging, I added "-Dclass.load.trace=class+loader -Dclass.load.log.file=C:\oracle\10.1.3\OracleAS_1\logs\classloadlog.txt -Dclass.load.log.level=all" to the start-parameters portion under the OC4J component portion of the opmn.xml file as below:

<ias-component id="OC4J">
<process-type id="home" module-id="OC4J" status="enabled">
<module-data>
<category id="start-parameters">
<data id="java-options" value="-Xrs -server -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false -Dclass.load.trace=class+loader -Dclass.load.log.file=C:\oracle\10.1.3\OracleAS_1\logs\classloadlog.txt -Dclass.load.log.level=all"/>
</category>
....
