WebSphere® Optimized Local Adapters (WOLA) is a feature of WebSphere Application Server for z/OS® that manages communication between WebSphere Application Server and an external address space, such as CICS®, batch, or IMS™, that resides in the same logical partition.
You use WOLA with WebSphere Application Server for z/OS to perform bidirectional exchanges between your z/OS programs (COBOL or PL/I programs) and Rule Execution Server.
You must set the WOLA-related variables in the SHBRPARM(HBRINST) member before you configure your execution environment.
