Failed To Obtain Debug Messages While Enable OC4J Debug Option In 10.1.3.x (Doc ID 1249404.1)

Last updated on AUGUST 28, 2018

Applies to:

Oracle Containers for J2EE - Version 10.1.3.0.0 to 10.1.3.5.0 [Release AS10gR3]
Information in this document applies to any platform.

Symptoms

OC4J debug options were enabled (see document section below) in OC4J java option, but it failed to generate the corresponding debug messages in the OC4J log file under opmn/logs directory. This issue only occurs in 10.1.3.x but not in earlier versions.

See debug options in

Oracle  Containers for J2EE Configuration and Administration Guide
10g (10.1.3.1.0)
Title: Table 4-3 OC4J Debug Properties
https://download.oracle.com/docs/cd/B32110_01/web.1013/b28950/sysprops.htm#CHDFCCBF



For example debug settings in opmn.xml:

<ias-component id="default_group">
<process-type id="home" module-id="OC4J" status="enabled">
<module-data>
<category id="start-parameters">
     <data id="java-options" value="-Dhttp.session.debug=true......."/>
</category>
...
</module-data>
</process-type>
</ias-component>


As expected result, the default_group~home~default_group~1 log under opmn/logs should then contain session debug messages for any session related events:

10/10/21 14:18:19 FINE: EvermindHttpServletRequest.unprivileged_getSession EvermindHttpServletRequest.getSession(), session=null
10/10/21 14:18:19 FINE: EvermindHttpServletRequest.unprivileged_getSession Requested Id is 0a9f0d0130d54f712a1cdd8a46c1a7ca8d26300a539e.e3aMahaMb3iLe34Mbh8Ma30Obhr0

10/10/21 14:38:44 FINE: EvermindHttpSession.destroy Call stack of invalidate()java.lang.Throwable: invalidate() called


Those corresponding debug messages are not generated in the OC4J log after enabled the debug option.
