How to Implement HA Automatic Restart Management

High Availability (HA) is a system design approach such that when a system fails, users can continue working on another system. For example, if the LPAR fails where CA Chorus is running, users need instant access to a secondary LPAR running the product.

This scenario explains how a system administrator and security administrator implement HA. Doing so can save time and money because users do not lose access in a single-fault scenario.

For CA Chorus HA, you configure the product to integrate with the z/OS Automatic Restart Management (ARM) facility. If a failure occurs, this facility provides the following HA options:

• Automatically restart an address space on the same system.
• Restart the address spaces on another system in a sysplex.

  

  To implement the ARM facility, complete the followings steps:

1. Review Prerequisites.
2. Identify How to Manage an Alternate LPAR Failure.
3. Configure XCF Administrative Data Utility Permissions.
4. Configure Permissions for the CA Chorus Started Task User.
5. Define the Restart Policies for the Started Tasks.
6. Modify the Started Task JCL for the ARM Wrapper.
