There are couple of changes have come with OIM11gR2.
a) Application Instance support for provisioning
> OIM11gR2, While provisioning, application instance is being used. Application instance is a new abstraction used in 11g Release 2 (11.1.2). It is a combination of IT resource instance (target connectivity and connector configuration) and resource object (provisioning mechanism).
> In earlier version of Bulkload utility, Accounts used to get provision using IT resource and Resource object directly whereas in this release, Bulkload will prompts for application instance name and proceed with the provisioning of accounts.
> If end user is not aware of application instance then he can fall back on earlier mechanism of provisioning using IT resource and Resource object directly.
b) Publish roles to organization
> As per new authorization model in OIM11gR2, Entitlements(or entities that can be requested) needs to be published to a organizations then only entities will be accessible/viewable.
> Enterprise roles: These are roles that users (depending on the permissions granted) can create in Oracle Identity Manager and request for by using the request catalog or Bulkload utility.
> In this version of Bulkload utility, we can publish the roles to organization with include/exclude hierarchy option. This can be achievable via editing CSV file or DB table.
> By default, Bulkload publish roles to TOP with include hierarchy.
