Outbound calling using WOLA

The WebSphere optimized local adapter (WOLA) uses high-performance communication services called Local Comm to enable cross-memory transfers between the IBM Process Server for z/OS and external address space programs.

A REGISTER API call registers the external address space with the Process Server for z/OS. During this call, the external application that runs in CICS or IMS, or as a batch server indicates the cell, node, and server that the external application communicates with. The external application also provides a register name and information about the maximum number of established connections.

For outbound requests, the external address space applications must first use one of the native WOLA APIs Host Service or Receive Request and be identified as target services. On the connection factory, specify the register name and on the interaction specification, specify the service name. Process Server for z/OS uses these specifications to call the target service.

Using WOLA, business processes and services on Process Server for z/OS can call CICS or IMS transactions, or batch programs on z/OS.
