ERROR WHEN RETURNING A PL/SQL TABLE?

Question

Hi,
I try to call a Oracle 9i function from Oracle 8i via TEST9.WORLD dblink.
The function returns me a pl/sql table.
It compiles but when I try to execute I get the following error
The following error has occurred:
ORA-02068: following severe error from TEST9.WORLD
ORA-06512: at "TBSDEV.GETDATA", line 12
ORA-06512: at line 2
Note: I test the code in a single database instance
and it works fine. The problem occurs when I move the getData function to 8i and
call the package function via a dblink.
What can I do?
what might be the problem?
Does not Oracle permit us move table of records between 2 database instances?
]f it does not, it is very tragic because we can get the SQL Server record sets to
Oracle 9i through a gateway but we could not move these records sets within Oracle?
!!!!!!!!!!! All of the code .} use is listed below.
thanks in advance.
--BELOW IS MY PACKAGE IN ORACLE 9i SERVER
--THIS PACKAGE GETS DATA FROM SQL SERVER THROUGH TRASPARENT GATEWAY
CREATE OR REPLACE package tgw is
TYPE RefCursorType IS REF CURSOR;
TYPE HisseRecordType IS RECORD( HisseAd VARCHAR2(20) := '' );
TYPE HisseTableType IS TABLE OF HisseRecordType INDEX BY BINARY_INTEGER;
mytable HisseTableType;
myrecord HisseRecordType;
function getRecords return HisseTableType ;
end;
CREATE OR REPLACE package body tgw is
function getRecords return HisseTableType is
rc RefCursorType;
htable HisseTableType;
hrec HisseRecordType;
BEGIN
"ahtha"."getHisseSenetleri"@ata(rc); --CALLS SQL SERVER STORED PROCEDURE
FOR i IN 1..10 LOOP
FETCH rc INTO htable(i);
END LOOP;
CLOSE rc;
RETURN htable;
END;
end;
--HERE IS THE PROCEDURE IN OUR MAIN ORACLE 8i SERVER
-- TGW9i ]S THE dblink to the oracle 9i
-- THE BELOW CODE COMPILES BUT GIVES THE ERROR I MENTIONED ABOVE
PROCEDURE getdata is
htable tgw9i.mytable%TYPE;
hrec tgw9i.myrecord%TYPE;
begin
htable:=tgw9i.getRecords(10);
FOR i IN 1..10 LOOP
DBMS_OUTPUT.PUT_LINE(htable(i).HisseAd);
END LOOP;
end;

Answer 1

The problem might be passing PL/SQL Tables or Records over your database link. You might run some more simple tests with PL/SQL Records and Tables over your link.
1) I still suggest you use a GLOBAL TEMPORARY TABLE to pass your information, attempt to do everything in a few SQL statements to pass the informaiton. And then process it on the other side. Database links tend to be a bit slow, and so you want to try to reduce the number of times you extract information through the link.
2) Someone else may have more experience with DB links, and calling procedures through them.
I wish you luck that you find your answer soon,
