Transform the schema name with APPLY_DML_HANDELER

Question

Hello:
I have referred following notes, but I was trying to transform the schema name from schema_name_A to Schema_name_B in APPLY_DML_HANDELER, which does not seem like working.
264035.1 How To Transform Schema Name In Streams
309575.1 How To Transform A Schema Name In Streams for DML and Simple DDL Operations
313766.1 Streams Heterogeneous Apply To SQL*Server
Please confirm, if what I am trying to do it doable or not? Below is handler code.
CREATE OR REPLACE PROCEDURE APPLY_DML_HANDLER(in_any_data IN SYS.ANYDATA) IS
v_in_lcr SYS.lcr$_ROW_RECORD;
v_in_lcr_status PLS_INTEGER;
BEGIN
v_in_lcr_status := in_any_data.GETOBJECT(v_in_lcr);
v_in_lcr.set_object_owner('CSRREP');
v_in_lcr.EXECUTE(TRUE);
END;
All gets compiled good and runs, but dba_apply_errors shows Ora-23416.
Thanks,
Rohit

Hi Rohit,
ORA-23416: table "string"."string" does not contain a primary key constraint
Cause: The master table does not constaint a primary key constraint or the primary key constraint has been disabled.
Action: Create a primary key constraint on the master table or enable the existing constraint.
It is doable. I've done already done that in 9i. Be conscious that that kind of handler is executed for each LCR. So, that's highly paid.
I think there are new features to do it in a better way in 10g but I haven't tried it yet.
I had a bug somewhat similar that I fixed doing the following:
dbms_rule_adm.grant_object_privilege(
privilege => SYS.DBMS_RULE_ADM.EXECUTE_ON_RULE_SET,
object_name => v_ruleset_name,
grantee => v_new_owner
);
