Configuring VTAM and SNA Communication Parameters

Configuring an LU6.2 transport requires a usable SNA network configuration. Defining a Comm. Bridge to use LU6.2 requires certain information from VTAM and other components that define the SNA Network such as NCP definitions. You need to be familiar with the task required to configure the third party products that provide the SNA support to the Comm. Bridge.

For a list of third party products offering SNA supported for use with the Comm. Bridge, see the CA Gen Technical Requirements document.

You will need to obtain parameters related to the z/OS host's SNA environment. For a CICS or IMS target server, these parameters are found in the VTAM and NCP configuration files. They include:

• For CICS, the VTAM application LU name of the region
• For IMS, the VTAM application LU name for the z/OS APPC address space (for IMS)
• For certain SNA products, the Local LU Alias the Comm. Bridge will use when allocating its LU6.2 conversations.
• The VTAM Log Mode table entry of a logon mode entry that allows for parallel LU6.2 sessions

The details for setting VTAM, NCP, CICS, and z/OS APPC address space parameters can be found in your IBM or Microsoft documentation associated with their respective SNA product.
