Diwas, so I have a clarification question here, is the platform still IBM, or is the SQL connection to a new source such as Oracle or Microsoft etc...? When I did some Google searching, it appeared IBM may have something related here, so I just wanted to try to get further clarification on exactly what all has changed here?
Just a side note, these issues are generally related to the Connector/Driver being used for the connection to the backend source, not really a QlikView message, we are simply reporting what the Connector/Driver gave us, so you will likely find better information to troubleshoot on the Connector/Driver vendor Community in this case...
