Known and Open Issues
Following is the known and open issue of Oracle Identity Manager:

This is a class loading issue observed with OIM 11g, after deploying iiq servlet(iiq.war) on Weblogic OIM Managed Server.
Resolution: Create another, empty WLS(Weblogic)Managed server next to the OIM Managed Server and only deploy the IIQ Servlet. Also, update the Xellerate.properties file by un-commenting the attribute java.naming.provider.url. This Url needs the host name of the host where OIM managed server is deployed and the listening port of the OIM managed server.

The value of the Organizations.Key
attribute is 1 (float datatype).
For example, the AttributeRequest in the provisioning plan looks like the following:
<AttributeRequest name="Organizations.Key" op="add">
<Value>
<Long>1</Long>
</Value>
</AttributeRequest>
