How to enable Apache and Jserv Debugging in Oracle Apps 11i?

PURPOSE:-If a user experiences an error, request a screen shot of the error and any further error details that they can report.If the error is reproducible, enable the following middle tier debug settings and collect diagnostic information appropriately and upload to support for troubleshooting.

Looking for Jserv.log at $IAS_ORACLE_HOME/Apache/Jserv/logs then enable…
For Temporary purpose manually editing configuration files.
1) Shut Down Apache Server
2) Backup the existing files in the following files:
$IAS_ORACLE_HOME/Apache/Apache/logs
$IAS_ORACLE_HOME/Apache/Jserv/logs
$IAS_ORACLE_HOME/Apache/Jserv/logs/jvm
3) Enable debug logging for Apache
s_apache_loglevel=debug (In Context File)
Or
loglevel debug (In $IAS_ORACLE_HOME/Apache/Apache/conf/httpd.conf)
4) Enable debug logging for mod_jserv
s_apjservloglevel=debug (In Context File)
Or
ApJServLogLevel debug (In $IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.conf)
5) Enable debug logging for Jserv
s_oacorelog=true (In Context File)
Or
log=true log.channel=true log.channel.info=true log.channel.debug=true
(In $IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.properties)
6) Enable debug logging for Forms Listener Servlet JVM. (Optional)
s_oaformslog=true (In Context File)
Or
log=true log.channel=true log.channel.info=true log.channel.debug=true
(In $IAS_ORACLE_HOME/Apache/Jserv/etc/forms.properties)
7) Restart Apache
(If Context File had been edited in above steps then run autoconfig to update the configuration files.) 8) Replicate the Problem.
9) Review the following files from the $IAS_ORACLE_HOME/Apache/Jserv/logs directory
a) mod_jserv.log
b) jserv.log
c) All files from the $IAS_ORACLE_HOME/Apache/Jserv/logs/jvm directory These will
have filenames of the form jvm.jvm.stdoutstderr For example,
OACoreGroup.0.stderr
d) $COMMON_TOP/rgf/instance_hostname/javacache.log
