Enable Secure Communications for an Existing CA Process Automation System

If you previously selected HTTP as the protocol over which the Domain Orchestrator communicates, you can begin communicating over the secure HTTPS protocol.

Follow these steps:

1. Reinstall the Domain Orchestrator. Specify secure communication in one of the following ways, depending on your installation method:
   • If you reinstall the Domain Orchestrator interactively (Install the Domain Orchestrator), select Support Secure Communication.
   • If you create a response file for unattended Domain Orchestrator Installation, set the isSecure variable to true to enable secure (HTTPS) communications:

     isSecure=true
     

2. Enable secure communication by agents in one of the following ways, based on their configuration.
   • Verify that agents configured to use deprecated communication are automatically restarted. (Deprecated communication is the default setting for existing agents.) Start any agents that were shut down before the reinstall.
   • Reinstall agents that were previously configured to use simplified communication. (Simplified communication is configured by clearing the Use Deprecated Communication check box during agent installation.) Reinstall agents as described in Installing an Agent. Then start the agents.

   HTTPS is used for all the communication between agents and the Domain Orchestrator.

3. Verify that all process instances that are using existing SOAP attachments are complete.

   Note: Existing SOAP attachments are accessible over HTTP only.
