Choosing the correct CICS Resource Adapter to deploy in WebSphere Application Server

Technote (FAQ)


Question

Which CICS Resource Adapter should I use with my version of WebSphere Application Server (WAS) and my version of CICS Transaction Gateway (CICS TG)?

Answer

The resource adapter required to connect WAS and CICS TG depends on the versions of each product in use. The following table explains which RAR to select.

Note: The table below indicates compatibility between versions and does not imply support where the product has reached its end of support date. Lifecycle dates for CICS TG product are listed on the IBM Support Lifecycle pages.

Updated versions of these adapters can be found in SupportPac CC03 and recommended for use wherever applicable.

6.1        9.0       8.0 (remote mode only)
6.1        8.1       8.0 (remote mode only)
6.1        8.0       8.0
6.1        7.2       7.2
6.1        7.1       7.1
6.1        7.0       7.0
6.1        6.1       6.1 (remote mode only)


IMPORTANT NOTES:

  1. You cannot use a resource adapter with a higher version number to connect to a lower version of CICS TG. So, for example, you could not deploy the v8.0 resource adapter in WebSphere to connect to CICS TG v7.2.
  2. On distributed platforms, when WAS is using a 64-bit JVM, CICS TG must be configured in remote mode. CICS TG can run in local or remote modes when WAS is using a 32-bit JVM
  3. On z/OS, CICS TG v7 and above can run in local or remote mode when WAS is using either a 31-bit or 64-bit JVM.
  4. The JCA versions supported by WebSphere and CICS TG resource adapters must match. The table above takes this into account.
  5. You must use a resource adapter which matches your CICS TG platform. For example, if you have CICS TG for Multiplatforms, you cannot connect to it from a CICS TG for z/OS resource adapter.
  6. Using a resource adapter from an out of support version of CICS TG is not supported.
