You can view a list of installed and configured resource
adapters in the administrative console. Also, you can use the administrative
console to install new resource adapters, create additional configurations
of installed resource adapters, or delete resource adapter configurations.
Before you begin
A resource adapter is an implementation of the J2EE Connector
Architecture (JCA) Specification that provides access for applications
to resources outside of the server or provides access for an enterprise
information system (EIS) to applications on the server. It can provide
application access to resources such as DB2, CICS, SAP and PeopleSoft.
It can provide an EIS with the ability to communicate with message-driven
beans that are configured on the server. Some resource adapters are
provided by IBM; however, third party vendors can provide their own
resource adapters. A resource adapter implementation is provided in
a resource adapter archive file; this file has an extension of .rar.
A resource adapter can be provided as a standalone adapter or as part
of an application, in which case it is referred to as an embedded
adapter.
About this task
Use this task to configure a standalone resource adapter
archive file. Embedded adapters are installed as part of the application
installation. This panel can be used to work with either kind of adapter.
Procedure
- Open the administrative console.
- Select Resources > Resource adapters > resource_adapter.
- Set the scope setting. This field specifies
the level to which this resource definition is visible. For general
information, see Administrative console scope settings in the Related
Reference section. The Scope field is a read only string field that
shows where the particular definition for a resource adapter is located.
This is set either when the resource adapter is installed (which can
only be at the node level) or when a new resource adapter definition
is added.
- Configure the description. This field specifies
a text description of the resource adapter. Use a free-form text
string to describe the resource adapter and its purpose.
- Set the archive path. Use this field to specify
the path to the RAR file containing the module for this resource adapter.
This property is required.
- Set the classpath. The list of paths or JAR
file names that together form the location for the resource adapter
classes is set here. This includes any additional libraries needed
by the resource adapter. The resource adapter code base itself is
automatically added to the class path, but if anything outside the
RAR is needed it can be specified here.
- Set the native path. The list of paths which
forms the location for the resource adapter native libraries is set
here. The resource adapter code base itself is automatically added
to the class path, but if anything outside the RAR is needed it can
be specified here.
- Isolate the resource adapter if necessary. Use
this field to specify that this resource provider is loaded in its
own class loader. This allows different versions of the same resource
adapter to be loaded in the same Java Virtual Machine.
- Set the ThreadPool alias. The name of a thread
pool that is configured in the server that is used by the resource
adapter's Work Manager is specified in this field. If there is no
thread pool configured in the server with this name, the default configured
thread pool instance, named Default, is used. This property is only
necessary if this resource adapter uses Work Manager. This field does
not apply for the z/OS platform.
