This error sounds like your IBM DB2 ODBC driver is not installed correctly. I would check to see if it is working in the "ODBC Data Sources" application. You may need to contact IBM support help getting it installed correctly.
Thanks for your help!
I have uninstalled and reinstalled the IBM DB2 drivers on the machine but I am still facing the same issue.
Could you please suggest me what more can I do to resolve this issue.
Thanks in advance!
What are you connecting to? iSeries? Windows? Unix?
