(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.

For more information about optimized local adapters in development mode, read the Optimized local adapters deployment in development mode topic.

The optimized local adapters proxy EAR file can be found in the installableApps directory of the WebSphere Application Server for z/OS installation. The name of the EAR file is ola_proxy.ear. The EAR file can be installed using the administrative console or wsadmin scripting. The following is an example install command using jython:

AdminApp.install('/WebSphere/ND/AppServer/installableApps/ola_proxy.ear',
  '[ -nopreCompileJSPs -distributeApp -nouseMetaDataFromBinary
  -nodeployejb -appname ola_proxy -createMBeansForResources
  -noreloadEnabled -nodeployws -validateinstall warn
  -noprocessEmbeddedConfig -filepermission

  -MapModulesToServers [[ OLAProxyEJB.jar

Tasks

1. The optimized local adapters connection factory on the remote z/OS node is configured in the same way that a normal optimized local adapters connection factory would be configured. Each of the properties on the optimized local adapters connection factory can be overridden by the caller if the caller specified a value on the local node. For example, if the optimized local adapters connection factory on the remote z/OS node was configured to use the OTMAServerName 'IMS1', but the OLA connection factory on the local node specified OTMAServerName 'IMS2', the local node's specification would be used.
2. Security settings on the remote z/OS node can have an impact on which actions the local node is allowed to perform on the remote node. The user on the local node can specify a user ID and password to allow work on the remote node to run using that identity. Currently, this is only useful for running work in CICS using the optimized local adapters link server, where the user is logged into CICS and the target transaction is started using that user ID. Additionally, since the local node uses Remote Method Invocation over Internet Inter-ORB Protocol (RMI-IIOP) to communicate with the optimized local adapters proxy EJB, transport security settings can be used to prevent unauthorized users from using optimized local adapters in development mode.
