Properties of a generated EIS export binding

The properties of an EIS export binding are shown in the properties view of the assembly editor after generating the SCA artifacts using the enterprise service discovery wizard.

Prerequisite: You should have a module and an export with an EIS binding.
This section describes the EIS export binding properties you would have and could modify after generation of SCA artifacts by the enterprise service discovery wizard. Why would you modify the values in the properties? You might want to change the size of log and trace files or user names and passwords. In this set of steps, we will look at the properties view where these changes could be made.

After generating an EIS export binding with the wizard, you can also use hover help to get descriptions of the fields in the properties view.

  1. To see the EIS export binding properties, open the export in the assembly editor. Right-click the export and from the contextual menu, select Show in Properties. Select the Binding tab. The name of the adapter, the data binding class name and the function selector class name are shown. You can add a binding description.

  2. Selecting the Endpoint configuration tab and the Connection tab, opens the connection properties. You may specify a JNDI lookup name. If a JNDI lookup name is specified, the activation specification class and its properties will be disabled. In our case, a JNDI lookup name was not specified. The Activation Spec Properties section specifies the properties for the activationspec class, which represents the configuration required to establish the connection between the service and the EIS system. Specifically, these properties specify the database name, the user id and password, polling period and credentials. Show Advanced specifies the listener type.

  3. Selecting the Endpoint configuration tab and the Resource Adapter tab, specifies the resource adapter name, class name and the properties of the resource adapter. The name of the resource adapter needs to match the name of the resource adapter as it is deployed. If the resource adapter is embedded in the module, then the name must be the application name (that is, the module name)+'App'+'.'+'<display name of the resource adapter>', as you see it presented here. If the resource adapter is not embedded in the module, then it must match the name of the resource adapter as it is installed on the server.

  4. Selecting the Method bindings tab, provides interaction information at the method level. Specifically, methods and, if necessary, data binding classes for input and output at the method level.

  5. Selecting Security attributes and expanding the Authentication Properties section opens the authentication properties. The J2C authentication data entry name is shown (if it had been specified when the component was developed). If Show Advanced is selected, authentication properties are opened such as the level of the authentication; for example, at the container level.

  6. Selecting the Performance attributes tab shows performance-related properties. The Interaction Style property can have these values: sync (default), async or any. Select sync if you want a synchronous form of delivery; that is, the transfer of data will take place in real time. Select async if you want an asynchronous form of delivery; that is, the transfer of data will be passed to a messaging system where it will be stored and passed on to the target component. Selecting any will result in the sync behavior. The Asynchronous Reliability property can have these values: assured (default) or bestEffort. Select assured if you want a message to persist through a transaction. In other words, if you want guaranteed delivery of the message. Select bestEffort if you want a high throughput of messages and your application can accept and handle the loss of a message, as persistence is not guaranteed.
