Managing the VTAM SAW (session awareness) interface

MainView for IP uses the IBM VTAM SAW interface (CNMI application) to collect session awareness data by connecting to the ISTPDCLU VTAM application.

The VTAM session data is stored in a MainView for IP data space and then written to history files at each defined interval. MainView for IP displays both real-time and historical data for any VTAM session for the LPAR where the MainView for IP PAS runs.

You can collect session awareness data by defining a VTAM application, so that MainView for IP can open an access control block (ACB) and acquire a session with the ISTPDCLU application. The default name of the ACB is MVIPCNMA. You can specify the name of the ACB on the MainView for IP Saw Configuration view (MVIPSAWD).

Note

The ISTPDCLU VTAM application has a session limit of 1 for the SAW data session. Only one product's VTAM application at a time can acquire a session with the ISTPDCLU application on each LPAR.

The MVIPSAWD view displays the current status of the ACB. If MainView for IP is connected to the ISTPDCLU application and is collecting data, the status Open/Active is displayed on the view. Also, MainView for IP writes the following message to the MainView for IP PAS job log:

BMC257017I MAINVIEW/IP SAW interface connected to ISTPDCLU, VTAM session data will be collected.
