Configure Endpoints for High Availability

After you installed and configured the primary and secondary Enterprise Management Servers, you set up the CA ControlMinder endpoints to work in a high availability environment.

To configure endpoints for high availability

1. Install CA ControlMinder with the Advanced Policy Management Client feature enabled on the endpoint.

   The CA ControlMinder endpoint is installed.

2. Open a command prompt window on the endpoint and enter the following command:

   dmsmgr -config -dhname names
   

   This command configures the endpoint to work with the comma-separated list of Distribution Hosts.

   Note:For more information about the dmsmgr utility, see the Reference Guide.

3. Set the Distribution_Server configuration setting to list the Distribution Servers, separated by a comma:

   ssl://ds1.sample.com:7243, ssl://ds2.sample.com:7243
   

4. Save the settings.

   You have configured a list of Distribution Hosts and Distribution Servers with which the endpoint can communicate. The endpoint can now work in a high availability environment.

Example: Configure a List of Distribution Servers

The following example shows you how to configure a list of Distribution Servers for high availability.

During the installation of the endpoint, you are asked to enter the parameters of the Distribution Server that the endpoint communicates with. By default, this is the Enterprise Management Server. For high availability, you configure the endpoint to use the secondary Distribution Server when the primary Distribution Server fails.

1. Enter the names of the primary and secondary Distribution Servers:

   dmsmgr -config -dhname DH__@node1.computer.com,DH__@node2.computer.com
   

   A message appears confirming the action.

2. Specify the list of primary and secondary Distribution Server URLs.
   • UNIX: Modify the Distribution_Server parameter in the [communication] section of accommon.ini file.
   • Windows: Modify the Distribution_Sever value the Windows Registry. This parameter is found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\AccessControl\common\
     communication
