Configure the Primary Distribution Server

The Distribution Server handles communication between the Application Server and the endpoints.

You should complete this procedure if you install standalone Distribution Servers only.

Follow these steps:

From the Services window, stop the JCS, CA ControlMinder and Message Queue Server services.
Modify the services to start up manually and not automatically.
Create the PMD directory on the shared storage.
Configure the Distribution Host to use the shared storage, as follows:
1. Copy the DH directory to the shared storage. This directory is located in the following location:
```
DistServerInstallDir/APMS/AccessControl/Data/DH__
```
  DistServerInstallDir
  
  Defines the name of the directory where you installed the Distribution Server.
2. Copy the DH__WRITER directory to the shared storage. This directory is located in the following location:
```
DistServerInstallDir/APMS/AccessControl/Data/DH__WRITER
```
3. Copy the DMS__ directory to the shared storage. This directory is located in the following location:
```
DistServerInstallDir/APMS/AccessControl/Data/DMS__
```
4. 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 primary server is configured to use the DMS and DH on the shared storage.
Configure the Message Queue to use the shared storage, as follows:
1. Create a directory on the shared storage. For example: Z\MessageQueue
2. Copy the Message Queue datastore files to the shared storage. These files are located in the following directory:
```
DistServerInstallDir/MessageQueue/tibco/cfgmgmt/ems/data
```
3. Open the tibemsd.conf file for editing. This file is located in the following directory:
```
DistServerInstallDir/MessageQueue/tibco/cfgmgmt/ems/data
```
4. 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: F:\MessageQueue.
5. Save and close the file.
6. Open the queues.conf file for editing.
7. Append a comma and add the word "store=$sys.failsafe" to the end of every queue definition line, then save the file.
Start the CA ControlMinder services.

Example: Edit the queues.conf File

The following snippet from the queues.conf file shows you how amend the file to configure the Message Queue to use the shared storage.

queue/snapshots secure,store=$sys.failsafe
queue/audit secure,store=$sys.failsafe
ac_endpoint_to_server secure,store=$sys.failsafe
ac_server_to_endpoint secure,store=$sys.failsafe
