Mixed SNA and XCF connection
Figure 10 shows a mixed SNA and XCF connection. In Image 1, the controller and tracker are in the same address space. In Image 2, the tracker is connected using XCF. In Image 3, the remote tracker is connected using SNA with a VTAM® link. The spool is only shared between Image 1 and Image 2 (JES2 MAS). You must have two Data Stores, one installed in Image 2 and one in Image 3.
Note that the controller and tracker in Image 1 must have two different LU names. For each XCF connection, there must be a different XCF group name.
Key:
- FCC
- Data Store Communication task
- FL
- Fetch Job Log task
- FN
- Data Store SNA handler task
- MAJOR
- Controller/tracker main task
- NCF
- Network Communication function
Table 12 shows the initialization statements you can use to create the configuration in Figure 10.

Note:
In this example, the XCF groups or the
LU names for the communication partners are the following:
- XCFGRUCD
- The XCF group for the communication between controller and Data
Store. The members in the group are:
- XCFMEMCD
- Controller C1.
- XCFMEMD2
- Data Store D2.
- XCFGRUCT
- The XCF group for the communication between controller and tracker.
The members in the group are:
- XCFMEMCT
- Controller C1.
- XCFMEMT2
- Tracker T2.
- LU00C1D
- Controller C1, when communicating with D3.
- LU000D3
- Data Store D3.
- LU00C1T
- Controller C1, when communicating with T3.
- LU000T3
- Tracker T3.
