Develop applications that use optimized local adapters

Subtopics

• (zos) Use the optimized local adapters native APIs to invoke an EJB application from an external address space
  Use this task when to use the optimized local adapters native APIs to connect an external address space to CICS Application Server for z/OS and invoke an EJB application that is deployed on the application server.

• (zos) Use the Invoke API to call an enterprise bean from an external address space
  Use this task when to use the Invoke API to call a stateless session bean from an external address space that is in an application that is deployed on a locally attached WebSphere Application Server for z/OS .

• (zos) Calling an enterprise bean from an external address space within a client-initiated transaction
  Use this task when you call an EJB application that is deployed on WebSphere Application Server for z/OS from an external address space within a client-initiated transaction. The Customer Information Control System (CICS) environment is the only environment where transactional support is supported.

• (zos) Calling an enterprise bean from an external address space while ignoring the client transaction context
  Use this task when to call an EJB application that is deployed on WebSphere Application Server for z/OS from an external address space while ignoring the client transaction context.

• (zos) Use optimized local adapters to connect to an application in an external address space from a WebSphere application
  Use this task when to use the outbound APIs to connect to an application in an external address space from an application that is deployed on WebSphere Application Server for z/OS.

• (zos) Use the outbound APIs with the external address space or subsystem
  Use this task to create an interaction between the outbound APIs and the external address space or subsystem.

• (zos) Optimized local adapters for z/OS APIs
  WebSphere Application Server for z/OS optimized local adapters are supported by a set of z/OS native language callable services, or APIs, and the Java EE Connector Architecture (JCA).

• (zos) Optimized local adapters client-side code relocated to common storage
  With WebSphere Application Server Version 8.0.0.1, the amount of optimized local adapters code that needs to be loaded in the external client address space on behalf of the optimized local adapters APIs is reduced significantly.
