"result set not found"
*Cause: The client program tried fetching from a result set that is not
open anymore. Many gateways will, on execution of a stored procedure,
automatically close all result sets that were returned by any
previously executed stored procedure.
*Action: Check the documentation for the gateway that you are using and see
if it will automatically close currently open result sets each time
a stored procedure is executed. Then check if your client program is
doing anything that violates this rule. If it is, fix your program. If
it is not then contact Oracle customer support.
