Administer optimized local adapters

Subtopics

• (zos) Enable the server environment to use optimized local adapters
  We must enable the application server to receive inbound and outbound requests using the optimized local adapters support. Optimized Local Adapters for z/OS is a set of callable services (APIs) that give native z/OS applications the ability to make inbound calls to application server enterprise beans, and enable native programs to act as a server and accept requests from applications running in the WebSphere Applications Server.

• (zos) Optimized local adapters deployment in development mode
  Optimized local adapters can be used in development mode, which enables application developers to test their optimized local adapters enabled applications using a copy of WAS running on an operating system other than z/OS.

• (zos) Configure optimized local adapters in development mode on the remote z/OS node
  The optimized local adapters for z/OS proxy EAR file must be installed on the remote z/OS node to enable the local node to communicate with it. The EAR file has a single resource reference, named eis/ola, which must be resolved to an optimized local adapters connection factory installed on the remote z/OS node.

• (zos) Configure optimized local adapters in development mode on the local node
  The optimized local adapters for z/OS resource archive (RAR) file must be installed on the local node. When running on a non-z/OS platform, the optimized local adapters RAR file communicates with an instance of the optimized local adapters proxy EAR file on a remote z/OS node using Remote Method Invocation over Internet Inter-ORB Protocol (RMI-IIOP).

• (zos) WebSphere Optimized Local Adapter (WOLA) remote work request on an Enterprise Java Bean target
  This feature allows a client application such as batch, CICS , etc. to contact a remote WebSphere Application Server server instance hosting an application whose business logic execution and results are required by the client. The remote invocation is done by leveraging the BBOA1INV/BBGA1INV and BBOA1SRQ/BBGA1SRQ APIs and a proxy application (RemoteEJBProxy), which is shipped with WebSphere Application Server for z/OS.

• (zos) Enable optimized local adapters support in CICS
  The WebSphere Application Server for z/OS optimized local adapters support has some Customer Information Control System (CICS)-specific installation and setup requirements. Use this task to prepare the CICS environment to make outbound calls to EJB applications that are deployed on the local WebSphere Application Server and to be the target of calls from applications that run on WebSphere Application Server.

• (zos) Install the WebSphere BBOC, BBO$ and BBO# transactions in CICS
  We can install the WAS transactions, BBOC, BBO$ and BBO#, to support optimized local adapters with the Customer Information Control System (CICS) product. The system administrator must install and configure the transactions on CICS before the transactions are used. Then we can activate the optimized local adapters CICS Link server in the CICS environment.

• (zos) Use WLM with optimized local adapters
  Use this task to complete all the tasks necessary to use workload management (WLM) with optimized local adapters, including setting up WLM classification rules for Customer Information Control System (CICS) and WebSphere Application Server for z/OS.

• (zos) Enable optimized local adapters support in IMS
  The WebSphere Application Server for z/OS optimized local adapters support has Information Management System (IMS™)-specific installation and setup requirements. Use this task to prepare the IMS environment to make outbound calls to EJB applications that are deployed on the local WebSphere Application Server and to be the target of calls from applications that run on the Application Server.

• (zos) Enable optimized local adapters over OTMA/IMS support
  The WebSphere Application Server for z/OS optimized local adapters support has Information Management System (IMS)-specific installation and setup requirements. Use this task to prepare the IMS environment to make outbound calls from applications deployed on the local WebSphere Application Server to existing unchanged IMS transactions. For this support, optimized local adapters uses the IMS Open Transaction Manager Access callable interface (OTMA C/I).

• (zos) Calling existing IMS transactions with optimized local adapters over OTMA
  Existing unchanged IMS transactions that run as Message Processing Programs (MPPs) or fast path programs (IFPs) can be called using the WAS for z/OS optimized local adapters over Open Transaction Manager Access Callable Interface (OTMA C/I) support. This support is provided by a new set of native modules introduced with optimized local adapters that use the IMS OTMA C/I.

• (zos) Registering an external address space with a local daemon group or cell using optimized local adapters
  For optimized local adapters to make an outbound call to your local daemon group or an inbound call to a WAS cell, you must bind the current address space to the WAS daemon group and establish connection attributes.
