This is a reminder that Oracle E-Business Suite Release 12.0 will transition from Premier Support to Extended Support on February 1, 2012. After that date, new EBS 12.0 patches will be created and tested against the minimum patching baseline documented here:
All EBS 12.0 customers must apply the minimum patches listed in that document to be eligible for Extended Support. Those patches include the EBS 12.0.6 Release Update Pack, technology stack infrastructure updates, and updates for EBS products if they're shared or fully-installed.
Instead of applying the minimum baseline
If you haven't applied any of those updates yet, the simplest solution would be to apply the suite-wide EBS 12.1.3 Release Update Pack. That way, you bypass the 12.0 minimum patching requirements and immediately comply with the EBS 12.1 minimum requirements simultaneously.
As an added benefit of applying the 12.1.3 Release Update Pack, you will be eligible for the waiver of the first year of Release 12.1 Extended Support. For more details, about that fee waiver, see:
