Are my CICS products compatible with z/OS Version 2 Release 1?

Are you preparing for your next z/OS upgrade?
Do you need to confirm if your CICS Transaction Server (CICS TS) or one or more of your CICS Tools is compatible or needs any additional maintenance?
Does your site's IT governance policy require you to contact your software providers to confirm there are no compatibility issues for the z/OS upgrade?
These questions are typical in most shops, and very often when working with IBM, you may use the IBM Support Portal to open an SR (Service Request) to ask what if any compatibility or coexistence issues might be lurking related to your upgrade plans.
For the CICS portfolio of products, we have information in a few places depending on what you are upgrading. We keep information in the:
The CICS portfolio of software is not the only set of products faced with these planning questions, so now there is a more comprehensive solution to provide software product compatibility reports.
The detailed system requirements information are the complete lists of hardware requirements, supported operating systems, prerequisites and optional supported software, with component-level details and operating system restrictions. You can generate in-depth reports or just check operating system compatibility, or other compatibility information, hardware requirements, or end of service. You may access the Software Products Compatibility Reports website using the link below:
The IBM main product page in the 'System Requirements' tab has a button to 'view detailed system requirements' technote and to the Software Product Compatibility Reports.
The IBM main product page for the various CICS Tools products also has links directly to the Software Product Compatibility Reports for Server (and plug-in component if available).
If I click on the 'Plug-in' link I can see all the operating systems on Linux and Windows that are supported.
If I move over to the 'Prerequisites' tab, I can see the supported Eclipse Runtime.
You can also get to the Software Product Compatibility Reports link from the "Detailed System Requirements for CICS Transaction Server" technote.
For CICS TS and CICS Tools, both server side and plug-ins, we recommend you review items in this sequence:
The reason you would begin by looking at the Software Product Compatibility Reports, is that it typically will have the most current information on supported operating system versions. Next, check the product's Program Directory. If the product was recently made generally available (GA), it might already list z/OS V2.1 in the target systems. If it doesn't, the next place to look would be in the product documentation. There may have been a recent update specifically discussing an APAR which might have introduced some functional support for z/OS 2.1. If you don't find anything in the product documentation, the Program Directory will identify the name of the PSP (Preventive Service Planning) upgrade and subset. The PSP upgrade and subset might identify a specific APAR or refer to a technote for z/OS V2.1.
Let's use the CICS Performance Analyzer for z/OS Version 3 Release 1 product as an example. There are two newer versions (CICS PA 3.2 and 5.1), but let's say CICS PA 3.1 is what you are using and you just need to know if it will run ok on z/OS V2.1. If we start in the CICS PA 3.1 Program Directory GI13-0540-00, down in section 5.0, the Driving and Target system information is listed. It lists only z/OS V1.8 as required. The PSP information only has an update to the Program Directory to say that CICS PA 3.1 also supports CICS TS V2.2. So now what do you do? You need to know if CICS PA V3.1 will run ok on z/OS V2.1 and if any additional maintenance is required. So let's try the Software Product Compatibility Reports website.
I navigate to the website and fill in the form as follows:
When the report rendering completes, we see that CICS PA 3.1 is compatible with z/OS 2.1.
If the 'Notes' column indicates 'Yes' you can click the 'View' button to see any additional notes. In this case, it identifies the minimum z/OS level as 1.9.
Sometimes there is more significant information listed. If I check the z/OS 2.1 notes for CICS TS 5.1 for example, it lists specific APARs that are also needed.
So go ahead and take some time to familiarize yourself with the Software Product Compatibility Reports website. If you find anything missing, click on the 'Feedback Survey' and let us know.
