Communications protocol and distributed queuing

The distributed queuing facility provided with the base product feature of WebSphere MQ can either use APPC (LU 6.2), TCP/IP from IBM, or Unicenter TCPaccess Communication Server (formerly called SOLVE:TCPaccess). The distributed queuing facility is also known as the channel initiator and the mover.

If you want to use clients, the client attachment feature is needed as well (but we can administer clients without it).

You must perform the following tasks to enable distributed queuing:

• Choose which communications interface to use. This can be one of the following:

  • APPC (LU 6.2)

  • TCP/IP

• Customize the distributed queuing facility and define the WebSphere MQ objects required.

• Define access security.

• Set up your communications. This includes setting up your TCPIP.DATA data set if you are using TCP/IP, LU names and side information if you are using APPC. This is described in the WebSphere MQ Intercommunication manual.
