Reading CSF Key Fails when Running Upgrade Assistance (UA)

During the Oracle Identity Manager 11g (11.1.2.3.0) to 12c (12.2.1.4.0) one-hop upgrade, when you run Upgrade Assistance (UA) in readiness mode, OIM fails to read the CSF key.

To solve the issue, complete the following steps:

1. Open the Update jps-config-jse.xml file at location $DOMAIN/config/fmwconfig.
2. Go to the section <serviceInstance name="audit.db" provider="audit.provider">
3. In the serviceInstance section, add the following as the first entry.

   <property name="server.type" value="DB_ORACLE"/>

   Sample serviceInstance section:

   <serviceInstance name="audit.db" provider="audit.provider">
               <property name="server.type" value="DB_ORACLE"/>
               <property name="audit.loader.repositoryType" value="File"/>
               <property name="auditstore.type" value="db"/>
               <property name="audit.maxDirSize" value="0"/>
               <property name="audit.filterPreset" value="None"/>
               <property name="audit.maxFileSize" value="104857600"/>
               <property name="audit.db.principal.map" value="AuditDbPrincipalMap"/>
               <property name="audit.loader.jdbc.string" value="jdbcstring"/>
               <property name="audit.db.principal.key" value="AuditDbPrincipalKey"/>
               <property name="audit.loader.interval" value="15"/>
               <propertySetRef ref="props.db.1"/>
           </serviceInstance>
