Connection management Connections and communication between the Tivoli Identity Manager Adapter for SAP NetWeaver and SAP are managed by a layered Tivoli Directory Integrator connector design. As Figure 5-7 on page 34 shows, the user connector and the support data connector encapsulate instances of the RFC function component. The function component is the only layer within the architecture that interfaces directly with the JCo API. The JCo API abstracts the SAP librfc network API, which performs the actual network socket connections and communications. Communications between the adapter and SAP are based on the SAP RFC protocol. All variations of SAP connection configuration and connection establishment are supported by the Tivoli Directory Integrator SAP NetWeaver connectors, and are exposed and supported by the adapter. The dispatcher is responsible for the life cycle of the Tivoli Directory Integrator connectors. SAP connection parameter information, defined in SAP NetWeaver service configuration in Tivoli Identity Manager, is transferred between the Tivoli Identity Manager server and the dispatcher as required. The dispatcher initializes the connectors with the parameter details upon connector instantiation. As a consequence, the connectors attempt to establish and maintain a connection to the target SAP ABAP servers. Connection errors are reported to the Tivoli Identity Manager server.
5.5.2 Add operation Tivoli Identity Manager operations for adding new user account provisioning are handled by the add AssemblyLine of the Tivoli Identity Manager Adapter for SAP NetWeaver. Figure 5-8 illustrates the adapter execution in response to an add request from Tivoli Identity Manager.

The account attributes associated with the new account are sent from Tivoli Identity Manager. The dispatcher populates an input work entry and invokes the add AssemblyLine. An instance of the Tivoli Identity Manager SAP NetWeaver is deployed in add mode. Tivoli Directory Integrator passes the account attributes to the connector.
