Develop applications that use optimized local adapters on Liberty

Optimized local adapters enable high-performance calling between native-language applications on z/OS and business logic in a Liberty server environment.

Use the Liberty Invoke API to call an enterprise bean from an external address space
Use the WebSphere optimized local adapter (WOLA) Invoke API to call from an external address space to a stateless session bean that is deployed on a local Liberty server for z/OS.
Use the Liberty optimized local adapters APIs to invoke an enterprise bean from an external address space
Use the WebSphere optimized local adapter (WOLA) APIs to connect an external address space to a Liberty server and invoke a local stateless session bean.
Use the optimized local adapters to connect to an application in an external address space from a Liberty application
Use the WebSphere optimized local adapters (WOLA) APIs to connect to an application in an external address space from an application that is deployed on the Liberty server.
Use the Liberty optimized local adapters APIs to call services in an external address space
Use the WebSphere optimized local adapters (WOLA) APIs to call services on an external address space or subsystem from a Liberty server.
Optimized local adapters APIs on Liberty for z/OS
WebSphere optimized local adapters (WOLA) on Liberty are supported by a set of z/OS native-language callable services application programming interfaces (APIs) and the Java EE Connector Architecture (JCA).
IMS message formats for outbound messages
When you send messages from Liberty to IMS using OTMA, the zosLocalAdapters feature must convert the message from an IMS format to OTMA C/I format. To do this conversion, Liberty must know whether the request and response message segments are in LLZZ or LLLLZZ format.
