Use optimized local adapters for outbound support

Use this task when we are implementing the optimized local adapters support for calling programs in external address spaces from WebSphere Application Server for z/OS applications.

Use optimized local adapters to make outbound calls from an application running under WebSphere Application Server for z/OS to a server program running in an external address space, and make inbound calls to EJB applications that are deployed on a local WebSphere Application Server for z/OS server from an external address space.

The following illustration shows the flow when using optimized local adapters with Customer Information Control System (CICS ).The following illustration shows the flow when using optimized local adapters with Customer Information Control System (CICS).

The next illustration is the flow when using optimized local adapters with Information Management System (IMS™).

The following steps describe the process required to call a native language z/OS server program running in an external address space.

  1. Enable the server environment.

  2. Prepare an existing application.

  3. (Optional) Use the CICS environment.

  4. (Optional) Use the IMS environment.

  5. Register an external address space.

  6. Secure optimized local adapters for outbound support.

  7. Make outbound calls.

  8. (Optional) Monitor optimized local adapters.
