Using PL/SQL in OMS Reports

Question

I've written a pl/sql block report and I'd like to add it to the OMS reports.
Are there any examples or hints on how to do this ?
Thanks

Cloned canned report Oracle Database Configuration Summary.
Removed all input constraints from query so it reads as follows:
begin
declare
type cursor_type IS REF CURSOR;
result_cursor_out CURSOR_TYPE;
tgt_guid_in MGMT_IP_TGT_GUID_ARRAY;
start_date_in DATE DEFAULT NULL;
end_date_in DATE DEFAULT NULL;
query_string VARCHAR(6000);
begin
result_cursor_out := ?;
tgt_guid_in := ?;
start_date_in := ?;
end_date_in := ?;
query_string :=
'select o.database_name "DATABASE_NAME",
o.characterset "CHARACTERSET",
o.instance_name "INSTANCE_NAME",
o.national_characterset "NATIONAL_CHARACTERSET",
o.global_name "GLOBAL_NAME",
o.log_mode "LOG_MODE",
o.banner "BANNER",
o.default_temp_tablespace "DEFAULT_TEMP_TABLESPACE"
from mgmt$db_dbninstanceinfo o ';
open result_cursor_out for query_string ;
end;
end;
Original report allows target selection from a list of databases, I changed to a blank specific target, since I want an unrestricted listing.
When I try to run, I get this error:
Error rendering element. Exception: Closed Statement
I've tried various ways to get around the error to no avail.
What did I do incorrectly ?
Thanks
