Usage Notes

This section lists dependencies and limitations related to using the ACF2 resource adapter.

Administrators

TSO sessions do not allow multiple, concurrent connections. To achieve concurrency for Identity Manager ACF operations, you must create multiple administrators. Thus, if you create two administrators, two Identity Manager ACF operations can occur at the same time. You should create at least two (and preferably three) administrators.

If you are running in a clustered environment, you must define an admin for each server in the cluster. This applies even if it is the same admin. For TSO, there must be a different admin for each server in the cluster.

If clustering is not being used, the server name should be the same for each row (the name of the Identity Manager host machine).

Host resource adapters do not enforce maximum connections for an affinity administrator across multiple host resources connecting to the same host. Instead, the adapter enforces maximum connections for affinity administrators within each host resource.

If you have multiple host resources managing the same system, and they are currently configured to use the same administrator accounts, you might have to update those resources to ensure that the same administrator is not trying to perform multiple actions on the resource simultaneously.

Resource Actions

The ACF2 adapter requires login and logoff resource actions. The login action negotiates an authenticated session with the mainframe. The logoff action disconnects when that session is no longer required.

See Mainframe Examples for more information about creating login and logoff resource actions.

SSL Configuration

Identity Manager uses TN3270 connections to communicate with the resource.

See Chapter 53, Mainframe Connectivity for information about setting up an SSL connection to an ACF2 resource.
