This section provides information related to using the Top Secret resource adapter, which is organized into the following sections:
TSO sessions do not allow multiple, concurrent connections. To achieve concurrency for Identity Manager Top Secret operations, you must create multiple administrators. Thus, if two administrators are created, two Identity Manager Top Secret operations can occur at the same time. You should create at least two (and preferably three) administrators.
CICS sessions are not limited to one session per admin; however, you can define more than one admin if desired.
If you are running in a clustered environment, you must define an admin for each server in the cluster. This applies even if (as in the case of CICS) 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.
The Top Secret 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.
Identity Manager uses TN3270 connections to communicate with the resource.
See Chapter 53, Mainframe Connectivity for information about setting up an SSL connection to a RACF LDAP resource.
