Add a Node to the Domain Orchestrator › Install a Cluster Node for the Domain Orchestrator

Install a Cluster Node for the Domain Orchestrator

Users with PAMAdmin privileges can optionally add additional cluster nodes to a Domain Orchestrator. Clustering helps to balance the processing load across the hosts that are clustered. Clustering is a good way to promote high availability. For the Domain Orchestrator to be eligible for clustering, you must have installed a Load Balancer before you installed the Domain Orchestrator.

Verify the completion of prerequisites to installing a cluster node for the Domain Orchestrator. Then, install the cluster node.

Follow these steps:

1. Log in to the server where you plan to install this cluster node for the Domain Orchestrator.
2. Browse to the Domain Orchestrator URL and log in.

   https://Load-Balancer-hostname:8443/itpam
   

   http://Load-Balancer-hostname:8080/itpam
   

3. Click the Configuration tab
4. Click the Installation palette.
5. Click Install for Install Cluster Node For Domain Orchestrator.
6. If the digital signature cannot be verified, click Run to start the installation.
7. On the Welcome to the CA Process Automation 3rd Party Installer Setup Wizard, click Next.
8. Accept the license agreement, and click Next.
9. Specify the destination directory to install the Orchestrator node, and click Next.

   The installer creates the folder automatically if it does not exist.

10. On the Prerequisites for CA Process Automation Installation screen, click Next.

    The Completing the CA Process Automation Setup Wizard for prerequisites displays a Use Domain check box and a path. Verify that this check box is selected. The installation process uses the information gathered from the Domain Orchestrator installation. This check box is typically not changed during installation, but if you need to enter new information, click the check box and enter the new information.

11. Click Finish to launch the installation of the cluster node for the Domain Orchestrator.
12. On the Welcome screen, click Next.
13. Accept the license agreement, and click Next.
14. Accept the displayed path or browse to the Java Home Directory. Click Next.

    The JDK is validated, and the Orchestrator installation begins. It will take a minute to copy configuration files.

15. Complete the Configuration Screen, and click Next.

    Orchestrator

    Specifies the Orchestrator to which the cluster node is to be added. The Orchestrator selected from the drop down list must be configured with a Public Host Name that specifies the FQDN of the server where the load balancer is installed.

    Load Balancer Worker Node

    Specifies the node name, for example, node 2. This is the name of this node specified in the Apache workers.properties file, where hostname is the name of the host on which you are installing the cluster node:

    worker.node2.host=hostname.mycompany.com

    Note: The first installation of the Domain Orchestrator is node1. For the second node, type node2.

16. View the Company Name, and click Next.
17. Enter the certificate password, and click Next.

    Certificate Password

    Specifies the same certificate password that was entered during the installation of the previously installed nodes of the Domain Orchestrator.

18. Verify the entries on the General Properties for the Orchestrator. Most of the settings derived from the Domain Orchestrator installation. Click Next.

    Server Host

    Specifies the FQDN of the host where this cluster node for the Domain Orchestrator is being installed.

19. Specify a Start Menu Folder, and click Next.
20. View the PowerShell settings.
21. View the CA EEM Security settings, and click Next.
22. View the database settings for the repository (library) data store, and click Next.
23. View the database settings for the runtime data store, and click Next.
24. View the database settings for the reporting data store, and click Next.
25. Monitor the progress messages as setup installs the cluster node for the Domain Orchestrator on the computer where you initiated the installation.
26. Click Finish.

    The cluster node for the Domain Orchestrator is installed.
