Cause

This issue can be caused by an invalid value in the "server name" field in the "Common and required data source properties" section in the Datasource configuration.

This message can be caused if the server name is either missing or does not match the name of the server being configured.

Diagnosing The Problem

In the admin console look in the Datasource configuration under the "Common and required data source properties" section.

Make sure that the "Server name" contains the correct name of the server.

Check the resources.xml file under <resources.jdbc:JDBCProvider..<

and look for

name="serverName" type="java.lang.String" value="WrongOrNoName" description="The TCP/IP address or host name for the DRDA server.

Resolving The Problem

Correct the Server name to reflect the name of the respective server and is not null (empty/blank) either.
