Verify that other applications are not connected to a database
under the DB2 instance being affected. Verification might be necessary
if the program does not complete successfully.

errors or warnings that might have been generated. If the configuration
tools continue to show this warning message, restart the computer and
try to produce the warning again before contacting IBM Software Support.
