The  Critical Patch Update (CPU) for October 2015 was released on October 20, 2015.  Oracle strongly recommends applying the patches as soon as possible.

The Critical Patch Update Advisory is the starting point for relevant information. It includes a list of products affected, pointers to obtain the patches, a summary of the security vulnerabilities, and links to other important documents.

Supported products that are not listed in the "Supported Products and Components Affected" Section of the advisory do not require new patches to be applied.

Also, it is essential to review the Critical Patch Update supporting documentation referenced in the Advisory before applying patches, as this is where you can find important pertinent information.

The Critical Patch Update Advisory is available at the following location:

The next four Critical Patch Update release dates are:

  • January 19, 2016
  • April 19, 2016
  • July 19, 2016
  • October 18, 2016

    Hello, Robert.

    For your information: PSU combo for, Patch 21520444 is not shown neither during patch search, nor by URLs from MOS notes.

    We hope it will become available soon.

    Here are a couple of references that will help you learn more about ACS:

    1. ANNOUNCEMENT: Additional Coverage Options for 12.0.6 and 11.5.10 E-Business Suite Sustaining Support (My Oracle Support Doc ID 1596629.1).

    2. http://www.oracle.com/us/support/library/financials-legislative-updates-2051314.pdf

    Customers who will still be on Release 11.5.10 in 2016 but have not yet upgraded to one of our premier support release versions are highly recommended to contract for the Tier 1 service offering.

    Watch out for further annnouncements on this in due course.

    Hi, Jeff,

    I'm sorry to hear that you've encountered an issue with this.

    We can provide general conceptual guidance here, but I'm afraid that this blog isn't the best place to get technical support for specific issues like the one that you're working through.

    Your best bet would be to log a formal Service Request via My Oracle Support (formerly Metalink) to get one of our specialists engaged.

    Please feel free to forward your Service Request number to me if it gets stuck in the support process for some reason.
