Hi Abdullah,
Thanks for your quick reply. Actually, I ever tried to add the
("input-format"="text-input-format"), and the error becomes:
Message
Internal error. Please check instance logs for further details.
[EOFException]
The log file for it is:
EVERE: Unable to create adapter

The details are in attachment cc3.log. And the cc2.log is for the query
without ("input-format"="text-input-format").
Thanks
