ORA-24338

Question

Hi,
I created a simple procedure in one database and tried to access it from another as follows:
DB: abcq
user: abc
create or replace procedure myproc (pcat number, src sys_refcursor)
as
begin
open src for select cat_id "ID", cat_name "Category" from category where cat_id = pcat or pcat is null;
end;
I tested it in abcq:
var bc refcursor;
exec myproc(212,:bc);
print bc;
PL/SQL procedure successfully completed.
BC
ID Category
*212 Studies*
I then did the following in another database:
DB: abcd
user abc
created a database link dbq for user abc in db abcq.
tested the link:
select cat_id, cat_name from category@dbq where cat_id = 212;
CAT_ID CAT_NAME
*212 Studies*
Then I tried to execute the procedure I created remotely from abcd:
var bc refcursor;
exec myproc@dbq(212,:bc);
print bc;
PL/SQL procedure successfully completed.
ERROR:
ORA-24338: statement handle not executed
no rows selected
All this was in SQL*Plus.
I tried Oracle SQL Developer environment. In that case, the procedure was successfully completed and when I printed bc, it gave me the following:
BC
ID     Category
It gave the correct column headings, but no data!
I scoured the web, but was unable to find any answer. One thing I did notice in one of the Oracle documentation sites, and I paraphrase: '... any remote procedure call is assumed to be for an update...' which I thought was strange. So, my questions are:
Is it possible to execute a procedure that returns a cursor remotely and can we access the data in that cursor? If so, what am I doing wrong?
Thank you.

You can use a cursor variable in a server-to-server remote procedure call (RPC) only if the remote database is not an Oracle Database accessed through a Procedural Gateway.
