ORA-28538: result set not found Cause: The client programtried 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 documentationfor the gateway that you are using and see if it
will automatically close currently open result sets each time a storedprocedure is
executed. Then check if your client program is doing anything that violatesthis
rule. If it is, fix your program. If it is not then contact Oracle customersupport.
