Setting Up webMethods Broker to Run in a High-Availability Cluster Environment
There are three task categories when setting up webMethods Broker to run in an HA cluster environment:
*System and network administration tasks performed by the user's system administrators.
*Cluster hardware and software (for example, Veritas, HP ServiceGuard, IBM HACMP) installation performed by cluster installation consultants.
*webMethods Broker and HA script installation performed by a webMethods administrator.
The table below summarizes the steps for configuring webMethods Broker to run in an HA cluster environment. The table columns, User's SysAd, Cluster Vendor and webMethods Administrator, indicate that the responsible party for the tasks are the user's system administrator, cluster vendor's installation consultant and the webMethods administrator, respectively.
Important:
You must perform steps 7, 8, and 9 for each node.
Step No.

Test the entire HA installation with the webMethods Broker application running to ensure it functions (fails over) properly.
You can verify this two ways:
*A manual failover using the cluster's vendor-specific commands
*An automatic failover by provoking/simulating a webMethods Broker crash
