Oracle has officially released the latest Oracle Applications Technology update patch which is formally known as Oracle Applications Technology 11i.ATG_PF.H.delta.7 (RUP7). The patch number is 6241631.
The Oracle policy for Oracle E-Business Suite 11i Critical Patch Updates is very clear -
Oracle Applications Technology (ATG) Minimum Supported Baseline:
Beginning with the July 2007 Critical Patch Update (CPUJul2007), Oracle Applications Technology only supports the current and previous production rollups (RUPn and RUPn-1) as patching baselines for all 11i releases.
With the release of ATG RUP7, the minimum supported baseline for the October 2009 Critical Patch Update (CPU) will be ATG RUP6 or RUP7. Therefore, in order to apply the October 2009 Oracle EBS CPU patches, you must be on RUP6 or RUP7.
One advantage of applying RUP7 is that it contains Oracle Applications Technology (ATG) security fixes for core ATG products from the January 2005 Critical Patch Update (CPUJan2005) through the July 2009 Critical Patch Update (CPUJul2009). The following core ATG products are included in 11i.ATG_PF.H.delta.7: FND, OAM, OWF, FWK, JTT, JTA, TXK, XDO, ECX, EC, AK, ALR, UMX, BNE, and FRM. Note that this is a large subset of the 11i CPU patches, but does not include any functional module patches such as AP, iStore, etc. You still must review all previous CPUs for missing EBS CPU patches.
