context_page_description: IBM WebSphere Optimized Local Adapters is a functional component of IBM's WebSphere Application Server for z/OS that provides an efficient cross-memory mechanism for calls both inbound to WAS z/OS and outbound from z/OS. Because it avoids the overhead of other communication mechanisms, it is capable of high volume exchange of messages. WOLA is an extension to the existing cross-memory exchange mechanism of WAS z/OS, with WOLA providing an external interface so z/OS address spaces outside the WAS z/OS server may participate in cross-memory exchanges. WOLA supports connectivity between a WAS z/OS server and one or more of the following: CICS, IMS, Batch, UNIX Systems Services and ALCS. WOLA was first made available in WAS z/OS Version 7, Fixpack 4. Functional enhancements have appeared in subsequent fixpacks as documented in this article.
context_section_description: IBM WebSphere Optimized Adapters function support has been updated as new versions or fixpacks are released.  The function was first made available in WAS z/OS Version 7 Release 0 Fixpack 4 level (7.0.0.4).
