WCF Service

The Windows Communications Foundation (WCF) service implements the web services function in CA APM. The web services function lets you use a standards-based interface to build client applications that integrate with CA APM.

The CA APM web services let you create, search, update, copy, and delete CA APM objects from your external client application. Your assigned user role determines whether you have permission to access the web services in CA APM and also restricts the objects and data (classes and attributes) that you can view or modify.

• For the standard installation, the WCF Service is installed on an application server with user input. You can modify the WCF Service protocol setting.
• For a custom installation, the WCF Service is installed on an application server with user input. You must specify the server name for the component and you can modify the WCF Service protocol setting.

The following fields require explanation:

WCF Service Load Balancer IP/Host

The CA APM installation, by default, sets this field to the WCF Service server host name.

• In a single WCF Service server environment, you can enter the WCF Service server host name, or the WCF Service server IP address.
• In a multiple WCF Service server environment, you can enter either the WCF Service server host name, or the IP address of the Load Balancer.

Note: The WCF Service server can be registered with a different name in the Domain Name System (DNS) than what is registered as the WCF Service server host name. In this situation, specify the different name in this field.

You can change the configuration of the WCF Service component after you install the product.

Note: For more information about changing the component configurations and adding servers, see the Administration Guide.
