This one I received from Oracle today.
New Recommended Bundle Patch 9405592 is available for download from My Oracle Support now. This patch primarily enhances the Patching functionality offered by Oracle Enterprise Manager Grid Control.
This patch is cumulative and is a superset of the previously released bundles # 9132461, #8992470, and #8653501 that were released previously, and
