Update AutoSys Configuration for Tie-Breaker IP Address Change

Products

• Autosys Workload Automation

Issue/Introduction

An AutoSys Tie-Breaker server is being relocated or assigned a new IP address.
Guidance is required to ensure the AutoSys instance (Primary, Shadow, and Tie-Breaker) correctly recognizes the new network information without service interruption.

Environment

• Product: AutoSys Workload Automation
• Component: Scheduler / Application Server / Tie-Breaker

Resolution

When updating the IP address of a Tie-Breaker server while maintaining the same Hostname or Fully Qualified Domain Name (FQDN), follow these steps to ensure the AutoSys configuration remains synchronized:

1. Verify Configuration Files

Check the $AUTOUSER/config.$AUTOSERV file on the Primary, Shadow, and Tie-Breaker servers.

• Ensure there are no hardcoded IP addresses for the schedulers or application servers.
• Confirm that all references use the Hostname or FQDN Tie-breaker realted queries.

2. Update DNS

Coordinate with your network team to update the DNS records for the Tie-Breaker server.

• Ensure the new IP address is mapped to the existing Hostname/FQDN.
• Verify that DNS changes have propagated across the network before starting the maintenance window Tie-breaker realted queries.

3. Disable IP Caching

To prevent the Scheduler from using stale or cached IP information, it is recommended to disable IP caching:

• Set EnableIPCaching=0 in the AutoSys instance configuration.
• Restart the Scheduler to apply this change Tie-breaker realted queries.

4. Restart Services

After the IP change is complete:

• Restart the Tie-Breaker Scheduler and Application Server.
• Agent Refresh: If any agents report a "Missing" status, restart those agents to force a refresh of the hostname resolution to the new IP Tie-breaker realted queries.

Note: Broadcom recommends testing these steps in a lower environment first to confirm the specific behavior of your network configuration.
