OAM Auditing question

For OAM,

I am referring one link, for OAM auditing,

1. Run the RCU against the database. 2.Set up audit data sources for the audit loader and configure it for the OAM Server.
2. In the service instance specified in the domain file ($DOMAIN_HOME/config/fmwconfig/jps-config.xml),
3. enable database auditing by changing the value of the property audit.loader.repositoryType to DB. For example:
4. <serviceInstance name="audit.db" provider="audit.provider"> <property name="audit.loader.repositoryType" value="DB"/> <property name="auditstore.type" value="db"/> <property name="audit.loader.jndi" value="jdbc/AuditDB"/> <property name="audit.maxDirSize" value="0"/> <property name="audit.filterPreset" value="None"/> <property name="audit.maxFileSize" value="104857600"/> <property name="audit.loader.interval" value="15"/> <propertySetRef ref="props.db.1"/> </serviceInstance>
