Initializing subsystems in the sysplex

Overview

A BSA XCF capable subsystem must be defined and initialized on each LPAR where this subsystem is to be available.

Initializing subsystems

BSA XCF capable subsystems are initialized in the usual way with BST01ARI (see "BST01ARI: Initializing subsystem and security environment").

In addition to the usual parameters for the program, the parameters XCF=YES and XCF_PROD=nn must be defined in member BnnSSIxx for BSA XCF initialization.

The following message is issued when initialization has been successfully completed:

xxx9170I XCF - SUPPORT HAS BEEN ACTIVATED

Other parameters

The parameter GOTO_OCF=ssid only needs to be defined when initializing the non-sysplex subsystem on the LPARs in the sysplex. ssid is the SSID of the system inside the sysplex that contains the OCF parameters for communication with the system that is outside of the sysplex.

For information on when to use the XCF_GBAS parameter, see "Introducing BSA XCF Global Connect".

BnnSSIxx parameters for XCF initialization

Parameter name

Value

Description

Default

XCF

YES | NO

YES

Activates BSA XCF support

NO

Deactivates BSA XCF support

NO

XCF_PROD

nn

Two-digit product identifier of the subsystem

This parameter is required if XCF = YES.

none

XCF_GBAS

 

Enables the automatic start of the BSA XCF Global Connect component. There are two possibilities:

none

 

name

where name is the name of the started task that provides the address space. You can find a sample procedure in the BSA.SAMPLIB in member BETAGXCF.

 

 

-OR-

 

 

 

IEESYSAS.name

where name is an identifier added to IEESYSAS to enable the started task to be identified and controlled.

 

GOTO_OCF

ssid

This parameter is only required if you want to access a subsystem that is outside of the sysplex. Here, ssid is the SSID of the subsystem inside the sysplex that contains the OCF parameters enabling users (=TSO users, batch jobs, subsystems) in the sysplex to access the non-sysplex subsystem.

Do not set this parameter when initializing any of the subsystems that are to be active inside the sysplex.

none

Deinitialization

To redefine a BSA XCF capable subsystem ID as NOT BSA XCF capable:

  1. Specify XCF=NO in the active BnnSSIxx member (or remove or comment out this parameter).
  2. Run BST01ARI on all affected LPARs of the sysplex to reinitialize this subsystem.
