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.With the release of WebSphere Liberty Profile z/OS 8.5.5.2, WOLA is also supported for use with Liberty Profile z/OS servers. See below for documentation on that functionality.

Executive Introduction and Overview
The following two-page brochure provides a good overview of WOLA. When printed duplex in color on good paper stock, it makes an excellent handout for meetings and events.

Overview and Usage Presentation
This presentation walks you through WOLA, starting from a high-level and drilling down to details on specific functionality. One file consists of charts only; the second file consists of charts with speaker notes.
Liberty Profile z/OS WOLA Quick Start Guide
With the release of WebSphere Liberty Profile z/OS 8.5.5.2, WOLA is also supported with Liberty. The following document guides you through setting up and validating a basic Liberty WOLA environment.

Full Function WAS z/OS 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.

We are often asked about using WOLA with EJB 3.0 applications. That is possible. The following short document illustrates how that is done. Two sample applications are provided: one with no JNDI bindings for the EJB, and one with a bindings file.

WOLA and REXX
Edware McCarthy has produced a Techdoc on using REXX with the Optimized Local Adapters. The URL for his Techdoc is:
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."
ALCS Brochure
For those involved with ALCS, here is a two page brochure of the support offered by WOLA for it:

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.
