Cannot create a data source connection (WebLogic Server)

As part of the task to configure a data source on Oracle WebLogic Server, the IBM Content Navigator Configuration and Deployment Tool creates a temporary data source. If this temporary data source is not deleted properly, IBM Content Navigator cannot connect to the data source.

Symptoms

For the Configure Your Database and Data Source task in the IBM Content Navigator Configuration and Deployment Tool, you receive the following error when you click Test Database Connection:
The connection to the database cannot be established.
...
javax.management.RuntimeMBeanException:
weblogic.descriptor.BeanAlreadyExistsException: Bean
already exists:
"weblogic.j2ee.descriptor.wl.JDBCPropertyBeanImpl@19f6ef03
([test_ds_for_configmgr]/JDBCDriverParams/Properties/Properties[user])"
You also receive an error message in the WebLogic Server administration console if you attempt to delete the test_ds_for_configmgr data source entry before restarting WebLogic Server.

Environment

This task applies only to Oracle WebLogic Server users.

Resolving the problem

System administrator response:

Run the following steps to resolve the error:
  1. Restart WebLogic Server.
  2. Sign in to the WebLogic Server administration console.
  3. Delete the entry for the following temporary data source: test_ds_for_configmgr.
  4. If there is no temporary data source, there might be an existing JDBC XML configuration file in the Oracle/Middleware/user_projects/domains/domain_name/config/jdbc directory:
    1. Delete the jdbc.xml file that corresponds to your data source from the Oracle/Middleware/user_projects/domains/domain_name/config/jdbc directory on the administrative server. For example, the file might be named ICN_jdbc.xml
    2. Restart WebLogic Server.
  5. Rerun the Create a Data Source for Your Database task in the IBM Content Navigator Configuration and Deployment Tool.
