new alias definition might not be recognized by the client.
 You
have multiple Db2 instances
installed on your workstation, and the Db2 catalog
entries are defined in a Db2 instance
other than the currently used instance.

 Correct the database alias for the currently
used Db2 system, then try again.

and restart the workstation client, then try again.
 If you

respectively .db2pe under UNIX.
