I have many snapshots configured in my database.I have also created dbms_snapshot package used to refresh the snapshots,but when I try to manually try to refresh the snapshot using the package ,it gives me the following error.
Can anyone tell me why does it happen.
SQL> exec sys.dbms_snapshot.refresh('AMOLP.DEPT_SNAP','C');
begin sys.dbms_snapshot.refresh('AMOLP.DEPT_SNAP','C'); end;
ERROR at line 1:
