Enabling the server environment to use optimized local adapters
You 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.
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 WebSphere Application Server running on
an operating system other than z/OS.
Configuring optimized local adapters in development mode on the remote z/OS node
The optimized local adapters for z/OS proxy enterprise archive (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.
Configuring 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 enterprise archive (EAR) file on a remote z/OS node using Remote Method Invocation
over Internet Inter-ORB Protocol (RMI-IIOP).
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.
Enabling 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 your CICS environment
to make outbound calls to Enterprise JavaBeans (EJB) applications that are deployed
on your local WebSphere Application Server and
to be the target of calls from applications that run on WebSphere Application Server.
Installing the WebSphere BBOC, BBO$ and BBO# transactions in CICS
You can install the WebSphere Application Server 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 you can activate the optimized local adapters CICS Link server in the CICS environment.
Using 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.
Enabling 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 your IMS environment
to make outbound calls to Enterprise JavaBeans (EJB) applications that are deployed
on your local WebSphere Application
Server and to be the target of calls from applications that run on
the Application Server.
Enabling 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 your IMS environment
to make outbound calls from applications deployed on your 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).
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 WebSphere Application
Server 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.
