valid Command Line Processor command.  During SQL processing it returned:
SQL1024N  A database connection does not exist.  SQLSTATE=08003
> db2 ? SQL1024N

SQL1024N A database connection does not exist.

Explanation:  There is no connection to a database.  Other SQL
statements cannot be processed unless an SQL CONNECT was
previously executed.

The command cannot be processed.

User Response:  If the error occurred when disconnecting from the
database, continue processing.  If the error occurred on another
SQL statement, issue an SQL CONNECT statement and resubmit the
command or statement.

sqlcode:  -1024

Another way to get help fast is to copy/paste the error string into google (internet search engine). Especially Google Groups is very helpful. You usually get the answer on the very first screen.
