I am using db2 v9.1 on windows.
I could not start or update the db2 instance; even for any db2 command it is giving the same following error:
SQL6031N Error in the db2nodes.cfg file at line number "0". Reason code "3".
I checked the file db2nodes.cfg file in ...\sqllib\db2\ directory & its permission, its all seems to be correct. Correct Hostname and node number is properly specified there.
I am not able to get the solution. For me its all seems to be fine.
Can you please help me or give some clue for finding the solution?
