Predicting VCS Behavior Using VCS Simulator

VCS Simulator enables you to simulate and test cluster configurations. Use VCS Simulator to view and modify service group and resource configurations and test failover behavior. VCS Simulator can be run on a standalone system and does not require any additional hardware.

VCS Simulator runs an identical version of the VCS High Availability Daemon (HAD) as in a cluster, ensuring that failover decisions are identical to those in an actual cluster. VCS Simulator enables testing and tuning of multiple values governing the rules of failover, such as SystemList, Limits and Prerequisites, and Load and Capacity.

You can test configurations from different operating systems using VCS Simulator. For example, you can run VCS Simulator on a Windows system and test VCS configurations for Windows, Linux, and Solaris clusters. VCS Simulator also enables creating and testing global clusters.

You can administer VCS Simulator from the Java Console or from the command line.
