CICS® Transaction
Gateway can be used with earlier versions of the resource adapters.
CICS Transaction Gateway
can facilitate communications with CICS through
resource adapters that are at the same version as CICS Transaction Gateway or at an earlier version.
If you are migrating CICS Transaction
Gateway to a later version, you can optionally migrate the earlier
version resource adapters to the same level as CICS Transaction Gateway but this is not mandatory.
The following rules apply when using different versions of CICS Transaction Gateway and resource
adapters:
- You can use a remote Gateway daemon with earlier version resource
adapters that are still in support.
- You cannot use a remote Gateway daemon with later version resource
adapters.
- When using local mode, the resource adapter and CICS Transaction Gateway versions must be the
same.
- You cannot mix earlier and later versions of resource adapters
on the same JEE application server node.
Note: - To find out which version number a resource adapter has, see the
information provided by the application server for the resource adapter
version. For example if you are using WebSphere® Application Server, use the Administration
Console to view the deployment descriptor for the installed resource
adapter.
- The upward compatability for the resource adapters is maintained,
so that older resource adapters work with newer Gateway daemons, but
after a release of CICS TG
is out of support, no compatability testing is done for the out of
support resource adapters.
