Abstract: WebSphere Optimized Local Adapters (or "WOLA") is a high-speed memory-to-memory transfer technology function provided with WebSphere Application Server for z/OS. It provides an excellent mechanism for communicating between WAS z/OS and other systems such as CICS, IMS and Batch programs. WOLA first came available in 7.0.0.4 and has been enhanced several times since then.


Executive Introduction and Overview
History of Updates to WOLA
    Many functional enhancements have been added to the WOLA support since introduction in 7.0.0.4. The following chart deck provides a graphic timeline of the enhancements, with functional details and pointers to the product InfoCenter where additional details can be found.

Overview and Usage Presentation
WOLA Quick Start Guide
This "Quick Start Guide" provides a set of step-by-step instructions to enable WOLA in your WAS z/OS environment as well as in a CICS region, and it shows the essentials of usage for CICS and Batch. Included as well is an EAR file containing the OLASample2 application enabled for Basic Authorization. This is useful when testing identity assertion WAS into CICS with V7.
Native API Primer
Ready to start coding to the native APIs? This primer offers a guided walkthrough of the APIs, from simple to increasingly sophisticated. WOLA and REXX
    Edware McCarthy has produced a Techdoc on using REXX with the Optimized Local Adapters. The URL for his Techdoc is:

    http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102348

    From the abstract of that Techdoc: "In this Techdoc we supply a set of REXX programs that invoke the WOLA APIs providing another option for developing applications that take advantage of WOLA."

Other Source of Information

Previous V7 Documents
    The following document was written for V7. The InfoCenter search strings provided are still good for V8 and V8.5. The document references V7-only things such as the "olaInstall.sh" script rather than the newer "copyZOS.sh" shell script. This document is deprecated in favor of the "Quick Start Guide" provided above.
