Hi Guys,

I am using IBM VAJ 3.5 along with DB2 Database. I was working properly sometime ago. But suddenly I am started to get following error while starting the Persistent Name Server in WebSphere Test Environment Control Center.

The exception as follows.

[06.01.11 12:17:41:922 PST] 16b9 CreateNsTable W Failed to create tables java.sql.SQLException: Error loading JDBC driver: COM.ibm.db2.jdbc.app.DB2Driver

void com.ibm.ivj.control.node.NameServerRunner.main(java.lang.String [])
java.lang.Object java.lang.reflect.Method.invoke(java.lang.Object, java.lang.Object [])


And also getting display message as
"An error has occurred while starting the Persistent Name Server. com.ibm.ejs.EJSException: ; nested exception is:"


any one has idea about this error ?


Thanks,
Prabhu.

I'd examine your database settings, check to see if someone has changed any database properties, and make sure your database drivers are available.

None of them has changed the properties of my Database configuration. And all the DB drivers are in the right path. I have uninstalled the VAJ and re Installed But there where no chagne in the error message.
