Review Prerequisites

Complete the following tasks before starting this scenario:

Review the z/OS sysplex and coupling facility feature of the z/OS operating system. We recommend that you understand this facility before attempting to configure it. The following IBM manuals provide detailed information regarding how to configure Automatic Restart Manager (ARM) in a z/OS environment:
- z/OS MVS Setting up a Sysplex
- z/OS Communications Server IP Configuration Guide for configuring VIPA to direct browser requests
- z/OS Distributed File Service zFS Administration Guide
- z/OS MVS Sysplex Services Guide
Set up XCF data sets on your z/OS systems. The details of this prerequisite are outside of the scope of this scenario. For more information, see ARM in z/OS MVS Setting up a Sysplex. IBM provides sample JCL streams in SYS1.SAMPLIB to format the XCF ARM data set (IXCARMF) and define policies (IXCARMP0).
Configure the failover LPAR to meet CA Chorus security requirements. Minimally, configure the following items for the failover LPAR:
- CHORADM (run ETJI095x, where x indicates the security product (A for CA ACF2, T for CA Top Secret, and R for IBM RACF)
- CA Chorus resource class
- Passtickets
More changes vary based on the existing configuration of the failover LPAR.

Note: For a detailed list of all security requirements, see the Site Preparation Guide.
