Configure new J2C resource adapters
Use the wsadmin scripting tool to configure Java 2 Connector resource adapters with Resource Adapter Archive (RAR) files. A RAR file provides the classes and other code to support a resource adapter for access to a specific enterprise information system (EIS), such as the Customer Information Control System (CICS ). Configure resource adapters for an EIS only after you install the appropriate RAR file.
A RAR file, which is often called a Java Connector Architecture (JCA) connector, must comply with the JCA 1.5 and 1.6 Specification. For resource adapters to support JCA Version 1.6, there is added support for Java annotations in RAR modules. For more information on annotation support and metadata, see the topic, JCA 1.6 support for annotations in RAR modules.
Meet these requirements by using a supported assembly tool (as described in the Assembly tools article) to assemble a collection of JAR files, other runnable components, utility classes, and so on, into a deployable RAR file. Then you are ready to install the RAR file in Application Server.
There are two ways to complete this task. This topic uses the AdminConfig object to install resource adapters. Alternatively, we can use the installJ2CResourceAdapter script in the AdminJ2C script library to install a J2C resource adapter in our configuration:
AdminJ2C.installJ2CResourceAdapter("myNode", "C:\temp\jca15cmd.rar", "J2CTest")
The scripting library provides a set of procedures to automate the most common administration functions. We can run each script procedure individually, or combine several procedures to quickly develop new scripts.
- Launch the wsadmin script. See the topic Starting the wsadmin scripting client article for more information.
- Identify the configuration ID of the node to which the resource adapter is installed, as the following examples demonstrate:
Jacl:
set node [$AdminConfig getid /Cell:mycell/Node:mynode/]
Jython:
node = AdminConfig.getid('/Cell:mycell/Node:mynode/') print node
Example output:
mynode(cells/mycell/nodes/mynode|node.xml#Node_1)
- Identify the optional attributes.
The J2CResourceAdapter object does not require specific arguments. Use the following command to display the optional attributes for the J2CResourceAdapter object:
Jacl:
$AdminConfig defaults J2CResourceAdapter
Jython:
print AdminConfig.defaults('J2CResourceAdapter')
The following displays the command output that displays each optional attribute and the data type for the attribute, and denotes the default attributes:
Attribute Type Default name String description String classpath String nativepath String providerType String isolatedClassLoader boolean false archivePath String threadPoolAlias String Default singleton boolean false hACapability ENUM RA_NO_HA isEnableHASupport boolean false propertySet J2EEResourcePropertySet jaasLoginConfiguration JAASConfigurationEntry deploymentDescriptor Connector connectionDefTemplateProps ConnectionDefTemplateProps activationSpecTemplateProps ActivationSpecTemplateProps j2cAdminObjects J2CAdminObject adminObjectTemplateProps AdminObjectTemplateProps j2cActivationSpec J2CActivationSpec properties Property
- Set up the attributes of interest.
Determine the attributes to configure for the J2C resource adapter. In the following examples, the commands set the RAR file path to the rarFile variable and the name and description configuration options to the option variable:
Jacl:
(dist)
set rarFile c:/currentScript/cicseci.rar set option {-rar.name RAR1 -rar.desc "New resource adapter"}(zos)(iseries)set rarFile /currentScript/cicseci.rar set option {-rar.name RAR1 -rar.desc "New resource adapter"}
Jython:
(dist)
rarFile = 'c:/currentScript/cicseci.rar' option = '[-rar.name RAR1 -rar.desc "New resource adapter"]'(zos)rarFile = '/currentScript/cicseci.rar' option = '[-rar.name RAR1 -rar.desc "New resource adapter"]'
- Create a resource adapter.
Use the installResourceAdapter command for the AdminConfig object to install the resource adapter with the previously set configuration options, as the following examples demonstrate:
Jacl:
$AdminConfig installResourceAdapter $rarFile mynode $option
Jython:
AdminConfig.installResourceAdapter(rarFile, 'mynode', option)
Example output:
RAR1(cells/mycell/nodes/mynode|resources.xml#J2CResourceAdapter_1)
- Save the configuration changes. See the topic Saving configuration changes with wsadmin.sh for more information.
- In a network deployment environment only, synchronize the node. See the topic Synchronizing nodes with wsadmin.sh for more information.
