HCL Workload Automation, Version 9.4

HACMP for AIX scenario - Backup domain manager

HCL Workload Automation provides a degree of high-availability through its backup domain manager feature, which can also be implemented as a backup master domain manager.

The backup domain manager duplicates changes to the production plan of the domain manager. When a failure is detected, the switchmgr command is issued to all workstations in the domain of the domain manager server, causing the workstations to recognize the backup domain manager.

However there are cases where a cluster environment represents a suitable alternative:
  • Difficulty in implementing the automatic domain responsibility switch
  • Difficulty in switching jobs that should run on the domain manager to the backup domain manager
  • The need to notify the switch of a domain manager to the HCL Workload Automation network
  • A high-availability product addresses many of the coding issues that surround detecting hardware failures
  • Implementing high-availability for fault-tolerant agents cannot be accomplished using the backup domain manager feature
