21.5.4 Step 4: Setting up application server for distributed platforms
environment
In this section, we introduce how we set up the WebSphere Application Server for distributed
platforms environment.
Step 4-1: Installing the IMS distributed JDBC resource adapter
Before deploying applications, you must first set up WebSphere Application Server on the
non-z/OS client side by installing the IMS distributed JDBC resource adapter. WebSphere
Application Server on the client side requires only the IMS distributed JDBC resource
adapter,
imsjavaRDS.rar.
We install the IMS distributed JDBC resource adapter by performing the following steps:
1. From the client-side WebSphere Application Server administrative console, click
Resources, and then click Resource Adapters. This displays a list of resource adapters,
as shown in Figure 21-42.

2. Click Install RAR. A panel for installing the resource adapter opens, as shown in
Figure 21-43. Then, enter the Local path to the imsjavaRDS.rar file. Click
Next.

4. The IMS distributed JDBC resource adapter is listed, as shown in Figure 21-45.

5. Click Save to Master Configuration. The Save page opens. Under Save to Master
Configuration, click
Save.
Step 4-2: Installing the data source for the client application
Our client application will use the data source on the WebSphere Application Server for
distributed side to connect the WebSphere Application Server for z/OS and make the specific
ODBA connection with the PSB. The J2C properties on the WebSphere Application Server
for distributed platforms will be propagated to an instance of the IMS RDS data source
definition on the WebSphere Application Server for z/OS side. We install the data source for
our client application by performing the following steps:
1. In the left frame of the client-side WebSphere Application Server administrative console,
click
Resources, and then click Resource Adapters. This displays a list of resource
adapters.

2. Click IMS Distributed JDBC RA. A configuration panel opens, as shown in Figure 21-46.
Under Additional Properties, click
J2C connection factories.

3. Click New. A configuration panel opens, as shown in Figure 21-47. Enter the following
information:
Name: Display name of the J2C connection factory, in our case, imsjavaRDSRedBook
JNDI name: JNDI name of the J2C connection factory, in our case, imsjavaRDSRedBook
Click
OK.

Tip: To avoid the messages J2CA0107I and J2CA0114W, both of which can be
ignored, set the default values for the component-managed authentication alias and
container-managed authentication alias.
