Enabling logging in OIM 11G

Any custom applications such as, event handlers, schedule task, connectors, etc., to debug in the OIM 11g Server, we need to enable the logging.

Pre-Requisite

You need to add the logging configuration code in java class.

import java.util.logging.Level;
import java.util.logging.Logger;

private Logger logger=Logger.getLogger("blog.chella"); //Class name is blog.chella

Configuration of logs in logging.xml

Go to the $DOMAIN_HOME/config/fmwconfig/servers/OIM_SERVER directory and edit the logging.xml file.

Include log_handler inside log_handlers

<log_handlers>
    <log_handler name='bloghandler' level='FINEST' class='oracle.core.ojdl.logging.ODLHandlerFactory'>
        <property name='logreader:' value='off'/>
        <property name='path' value=/opt/chella/oimlogs'/>
        <property name='format' value='ODL-Text'/>
        <property name='useThreadName' value='true'/>
        <property name='locale' value='en'/>
        <property name='maxFileSize' value='5242880'/>
        <property name='maxLogSize' value='52428800'/>
        <property name='encoding' value='UTF-8'/>
    </log_handler>
</log_handlers>

Include logger inside loggers

<loggers>
    <logger name="Logger-Name" level="LOG LEVEL" useParentHandlers="false">
        <handler name="blog.chella"/>
        <handler name="console-handler"/>
    </logger>
</loggers>

Log Level	ODL Msg:Level	Description
SEVERE.intValue()+100	INCIDENT_ERROR:1	Serious problem caused by bug in product
SEVERE	ERROR:1	A serious problem but is not caused by a bug in the product.
WARNING	WARNING:1	A potential problem
INFO	NOTIFICATION:1	A major lifecycle event
CONFIG	NOTIFICATION:16	A finer level of granularity for reporting normal events.
FINE	TRACE:1	Trace or debug information for events
FINER	TRACE:16	Detailed trace or debug information
FINEST	TRACE:32	Very detailed trace or debug information

The FINEST log level will give the more detailed info. If you want to debug your connectors, schedule task, event handlers, etc, you can use FINEST log level.

Note: Make sure you have disabled FINEST level in production.
