XCF only connection

Figure 8 shows a JES2 MAS (shared spool) with two images. In Image 1, the controller and a tracker are in the same address space and connected via XCF. Image 2 contains another tracker. You need only one Data Store, which is installed in Image 2. The controller will request the Job Log from the Data Store using the FL subtask.
