Question: 

How to configure CA WA ESP to work with the Cross-System Coupling Facility (XCF)?

Environment:  

CA Workload Automation ESP Edition r11.4

Answer: 

CA WA ESP uses XCF for communication between 2 or more ESP subsystems (example: between an ESP Master and an ESP Proxy subsystem). 

To enable the use of XCF in CA WA ESP, code the following statements in the ESP initialization parmlib data set on the ESP Master and its Proxy subsystems: 

1. SYSPLEX GROUP(name) MEMBER(name). The GROUP name must be the same for this family of ESP Master and its Proxy subsystems. The MEMBER name must be unique for each ESP subsystem. 
2. XCF START SERVICE TRACKING: to enable job-tracking records to be transmitted from the ESP Proxy to the Master via XCF 
3. XCF START SERVICE DSTRIG: to enable data set triggering records to be transmitted from the ESP Proxy to the Master via XCF. 
4. XCF START SERVICE ROUTING: to enable the users to connect to an ESP proxy on any system in the sysplex, and route the commands to the ESP Master. This service requires add-on product CA WA ESP High Availability (FMID CD71B40) or CA WA ESP Service Governor (FMID CD70B40). 
5. XCF START SERVICE SCOREBD: to enable the users to view the ESP scoreboard (application and job status) on an ESP Proxy subsystem. This service requires add-on product CA WA ESP High Availability or CA WA ESP Service Governor. 

Best practice: 

If XCF is used between ESP masters, you can hare only what needs to be shared across the systems. This is done by coding initialization statement XMITMDL on the ESP Master subsystem to send a tracking model (tracking a group of jobs) to a destination node. 

Example:

    - DEFTM MODELX HISTFILE(HIST1): define a tracking model named 'MODELX'

    - TRACKDEF JOB NAME(PR-) MODEL(MODELX):  associate tracking model 'MODELX'  to jobs which name begins with PR.  TRACKDEF statements are defined in the Job Tracking Definition Table (JTDT).

    - XMITMDL ADD MODEL(MODELX) NETNODE(BSYS):  ESP Master to transmit tracking model 'MODELX' to node 'BSYS'.  XMITMDL statement is defined in the ESP Master subsystem init parmlib.
