Hi,
dml handler creation failes as below,
scott and walsh schemas are on the same database "ebis"
Done the normal streams configuration and started apply process.but at the
end dml handler creation fails.
Any idea on what i can be the issue on this..
SQL> CREATE OR REPLACE PROCEDURE generic_dml_handler(in_any IN SYS.ANYDATA)
IS
2 lcr SYS.LCR$_ROW_RECORD;
3 rc PLS_INTEGER;
4 command VARCHAR2(10);
5 old_values SYS.LCR$_ROW_LIST;
6 l_object_name varchar2(31);
7 BEGIN
8 rc := in_any.GETOBJECT(lcr);
9 command := lcr.GET_COMMAND_TYPE();
10 l_object_name := lcr.GET_OBJECT_NAME();
11 if (l_object_name='EMP') then
12 l_owner := lcr.GET_OBJECT_OWNER();
13 IF (l_owner = 'SCOTT') then
14 lcr.SET_OBJECT_OWNER ( 'WALSH');
15 end if;
16 end if;
17 lcr.EXECUTE(true);
18 END;
19 /
