Implementing CA ControlMinder High Availability on Linux Using Veritas Cluster Server

A High Availability deployment ensures that your CA ControlMinder Enterprise Management components continue to service requests if one or more components or servers fail. If the endpoints cannot connect to the primary environment, they connect to a secondary server until the primary environment is restored.

Your primary and secondary CA ControlMinder Enterprise Management Servers are located in the same datacenter accessing the shared hostname. If the primary environment fails, then the Veritas Cluster software enables switching the services and the secondary environment takes control.

The following diagram shows CA ControlMinder Enterprise Management in a High Availability environment.

As illustrated in the preceding diagram, a High Availability deployment has the following components:

• A primary (active) Enterprise Management Server and at least one secondary(passive) Enterprise Management Server.
• A clustered installation of a policy and reporting store and a user store.
• Shared storage that is accessible by both the primary and secondary CA ControlMinder Enterprise Management Servers.
• A shared host name.
• CA ControlMinder endpoints able to work with both the primary and secondary Enterprise Management Servers.

The following diagram shows the process to configure CA ControlMinder High Availability on Linux using the Veritas Cluster Server.

Perform the following steps:

1. Verify the prerequisites.
2. Configure the Primary Enterprise Management Server on Linux.
3. Configure the Secondary Enterprise Management Server on Linux.
4. Verify the High Availability setup.
