Enable Orchestrator for Remote Workflow Execution
Remote workflow execution might not start.
Problem
When you try to run a remote workflow from one Orchestrator server over another Orchestrator server, the
workflow might not start.
Cause
Orchestrator does not permit the usage of the default SSL certificates. After you install or upgrade
Orchestrator, a new self-signed certificate is generated. The newly generated SSL certificate is unique for
each Orchestrator instance. To run remote workflows, the primary Orchestrator server must trust the SSL
certificate of the remote Orchestrator server.
Solution
1 Verify that the remote and the primary Orchestrator servers are up and running.
2 Log in to the Orchestrator configuration interface of the primary Orchestrator server.
3 Click Network.
4 From the IP address drop-down menu select the IP address, which corresponds to the correct subnet
(do not use multi adapter addresses such as 0.0.0.0).
5 Click Apply Changes.
6 In the right pane, click the SSL Trust Manager tab.
7 In the Import from URL text box, type the IP address and port number of the remote Orchestrator
server:
remote_orchestrator_server_IP:8250
8 Click Import.
9 Click the Startup options tab.
10 Click Restart service to restart the Orchestrator server.
If your company policy permits the distribution of SSL keys to multiple servers, you can replicate the SSL
keystore. To do that, copy the contents of the install_directory\app-server\conf\security\jssecacerts
folder from the primary Orchestrator server machine and paste it to the same location on the remote
Orchestrator server machine.
Changing SSL Certificates
By default, the Orchestrator server uses a self-signed SSL certificate to communicate remotely with the
Orchestrator client. Orchestrator also provides an SSL certificate that controls user access to Web views. You
can change the SSL certificates, for example if your company security policy requires you to use its SSL
certificates.
When you attempt to use Orchestrator over a trusted SSL Internet connection, and you open the
Orchestrator configuration interface in a Web browser, you receive warnings that the connection is
untrusted (in Mozilla Firefox) or that problems have been detected with the Web site’s security certificate (in
Internet Explorer).
After you click Continue to this website (not recommended), even if you have imported the SSL certificate
as a trusted store, you continue to see the Certificate Error red notification in the address bar of the Web
browser. You can work with Orchestrator in the Web browser, but a third-party system might not work
properly when attempting to access the API over HTTPS.
