Configuring the Application Server › Define a Unique Communication Alias

Define a Unique Communication Alias

The application server requires an additional communication alias to communicate with CA Workload Automation EE and CA WA Agent for z/OS. The communication alias is set to INSTANCENAME_ABBREVIATEDHOSTNAME during the CA Workload Automation AE installation.

If the CA Workload Automation AE instance has multiple application servers, the communication alias for each application server must be unique. If an alias is not unique, you must define another alias for that application server. The application server does not start if it detects another application server with the same communication alias.

The default value is INSTANCENAME_ABBREVIATEDHOSTNAME. The abbreviated hostname consists of the last 12 characters of the node name excluding the domain name. For example, the communication alias of the application server on myhost.ca.com is set to ACE_MYHOST, where ACE is the name of the CA Workload Automation AE instance.

Notes:

• The scheduler also requires a communication alias to communicate with CA Workload Automation EE and the agent on z/OS. However, the communication alias for the scheduler is automatically set to INSTANCENAME_AGT (in uppercase). You cannot change this value.
• For information about configuring CA Workload Automation EE or the agent on z/OS to work with CA Workload Automation AE, see the Windows Implementation Guide.
• On UNIX, the equivalent configuration parameter is AutoServerAliasId.

Follow these steps:

1. Click Start, Programs, CA, Workload Automation AE, Administrator.

   The Instance - CA Workload Automation AE Administrator window opens.

2. Select an instance from the Instance drop-down list in the Settings pane.
3. Click the Services icon on the toolbar.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.

4. Right-click the application server and select Stop.

   The application server stops.

5. Click the Application Server icon on the toolbar.

   The Application Server - CA Workload Automation AE Administrator window appears.

6. Enter a unique communication alias in the Communication Alias Identifier field, and click Apply.

   Note: You can enter a maximum of 16 characters (in uppercase). If you specify this value in lowercase or mixed case, it is automatically changed to uppercase.

7. Click the Services icon on the toolbar.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.

8. Right-click the application server and select Start.

   The application server starts. The unique communication alias is defined for the application server. The application server uses this alias to communicate with CA Workload Automation EE and the agent on z/OS.
