Prerequisites to Installing the Domain Orchestrator

Consider configuring a load balancer for your first installation to prepare for later expansion. (Adding cluster nodes can be done when the need arises.)

Note: We recommend a hardware load balancer. See F5 Load Balancer Prerequisites. If this is not possible, we recommend NGINX as the software load balancer of choice. NGINX for UNIX is highly scalable. See NGINX Load Balancer Prerequisites.

Plan your initial CA Process Automation installation. For component requirements, see:

Follow these steps:

  1. Identify a host for the Domain Orchestrator that meets requirements.
  2. Verify that the host for the Domain Orchestrator has a supported JDK

    See JDK Prerequisites.

  3. Plan whether to locate supporting components on the host with the Domain Orchestrator.

    See Planning the Locations of Supporting Components.

  4. Identify the database server(s) to host the databases for the Library, Reporting, and Runtime data stores for the Domain Orchestrator.
  5. Prepare the databases.

    See Database Server Prerequisites.

  6. Identify the host for CA EEM, if a CA EEM is not already in use with another CA Technologies product.
  7. Evaluate configuration options for CA EEM.

    See CA EEM Prerequisites, including Prerequisites for Configuring NTLM Authentication.

  8. If CA EEM is configured with CA SiteMinder, consider configuring CA Process Automation to use the SSO capability.

    See Using CA SiteMinder with CA Process Automation.

  9. Optionally, set up a load balancer if you anticipate the need to cluster the Domain Orchestrator at a later time. See Setting Up a Load Balancer for Orchestrator Clustering.
  10. Record, in a secure location, the certificate password that you plan to set in the Certificate Password field for the Domain Orchestrator.

    Important! You must provide this same password when you install other Orchestrators or additional Orchestrator nodes. If you forget this password, you will need to reinstall every Orchestrator in your system beginning with the Domain Orchestrator. This same password is required when you upgrade to a new release.
