When you are working in a sysplex, you can also access and work with a subsystem (SSID) that is not part of that sysplex. In this case, communication takes place via OCF between one SSID inside the sysplex and an SSID outside of the sysplex.
OCF parameters must be set in the usual way in the LST members of each of the two subsystems: the subsystem inside the sysplex that is to be used to communicate with the outside, and the subsystem outside the sysplex. The OCF parameters can be set in the external subsystem itself, or in the BSA X-System Router Beta 02. We recommend that you use Beta 02. For more information, see "Establishing OCF communication via X-System Router (Beta 02)".
All the sysplex subsystems that are to be reached by the external subsystem must be defined as OCF_LOCAL on the sysplex-internal subsystem that is to be used to communicate with the outside. All the LPARS in the sysplex are then treated as a single LPAR by the OCF router task.
The subsystems inside the sysplex must be defined on each of the LPARs in the sysplex and initialized with the following parameters:
XCF=YES
XCF_PROD=product
The SSID of the external subsystem (i.e. the one outside the sysplex) must be defined on each of the LPARs in the sysplex and initialized with the following parameters:
XCF=YES
XCF_PROD=product
GOTO_OCF=ssid
This enables access to the external non-sysplex subsystem from the subsystems within the sysplex.
Do NOT define parameter GOTO_OCF when initializing the subsystems that are defined as part of the sysplex.
"Example: Communication between sysplex and non-sysplex" clearly illustrates the settings that need to be made and where they need to be made.
