Configuring data sharing groups for group-generic SNA access

You can configure a Db2 server for group-generic access to make requests and handle requests.

Before you begin

Tip: TCP/IP is the recommended communication protocol for communication with Db2 for z/OS®. Although SNA communication remains supported in Db2 13, SNA communication and the VTAM interface are deprecated, and support will be removed in the future. If your Db2 environment still uses VTAM communication, see Converting to TCP/IP communication from VTAM in Db2 for z/OS.

Procedure

To enable group-generic access to a data sharing group:

  1. Include information in the coupling facility for support of VTAM® generic resources (the ISTGENERIC structure).
  2. Define a generic LU name for the group.
  3. Configure the members to use the group's generic LU name when identifying themselves to remote subsystems.
  4. Identify the generic LU names of requesting data sharing groups.
  5. Identify the LU names of individual requesters, such as Db2 Connect and members of requesting data sharing groups.
