Configure the Secondary Distribution Server

The secondary Distribution Server handles communication between the Application Server and the endpoints in case the active Distribution Server fails to respond within a predefined interval.

Follow these steps:

1. Stop the JCS, CA ControlMinder and Message Queue Server services.
2. Modify the services to start up manually and not automatically.
3. Set the _pmd_directory_ registry key, under \ComputerAssociates\AccessControl\PMD, configuration setting to the full pathname of the shared storage directory you copied the DMS and DH to. For example: Z:\PMD.

   The secondary Distribution Server can now access the DMS and DH files on the shared storage. You have configured the Distribution Host to use the shared storage.

4. Configure the Message Queue to use the shared storage, as follows:
   1. Open the tibemsd.conf file for editing. This file is located in the following directory:

      DistServerInstallDir/MessageQueue/tibco/cfgmgmt/ems/data
      

      DistServerInstallDir

      Defines the name of the directory where you installed the Distribution Server.

   2. Set the value of the "store" token to point to the directory on the shared storage where you copied the datastore files to, for example: Z:\Datastore.
   3. Save and close the file.
   4. Open the queues.conf file for editing.
   5. Append a comma and add the word "store=$sys.failsafe" at the end of every queue definition line, then save the file.
5. Verify that the CA ControlMinder services on the secondary server are stopped.
