Oracle Job in case of heterogenous services

Question

I am trying to transfer some data automatically after every 30 min from MS Access to oracle. What I have done is-
1. Created a ODBC connection and DB link using that DSN and now I can access the data from Oracle to MS Access.
2. I have written a stored procedure that will transfer data from Access to Oracle.
3. Created a job that will execute the stored procedure after every 30 mins.
But when the job run it gives the following error.
ORA-04052: error occurred when looking up remote object ODMS.EMPLOYEE@ATTENDANCE
ORA-00604: error occurred at recursive SQL level 2
ORA-28513: internal error in heterogeneous remote agent
ORA-02063: preceding line from ATTENDANCE
Here, ODMS=schema name
Employee= Table name in MS Access
ATTENDANCE=Db link
Below is my Procedure
create or replace
procedure data_transfer_attendance
is
begin
execute immediate 'truncate table employee_oims' ;
insert into employee_oims select * from employee@ATTENDANCE;
end;
employee_oims=oracle table

Answer 1

1. my database link creation statements: create public database link ATTENDANCE  using 'ATTENDANCE (no user/pass was provided).
2. if I issue from SQLPLUS (as sysdba) select * from employee@ATTENDANCE, data get retrieved.
3. I I try to create the procedure from SQLPLUS it gives the following error-
Compilation errors for PROCEDURE SYS.DATA_TRANSFER_ATTENDANCE
Error: ORA-04052: error occurred when looking up remote object SYS.EMPLOYEE@ATTENDANCE
       ORA-00604: error occurred at recursive SQL level 1
       ORA-28513: internal error in heterogeneous remote agent
       ORA-02063: preceding line from ATTENDANCE
Line: 1
Text: create or replace procedure data_transfer_attendance
4. I h ave also tried after adding the "commit". Same result.
