Getting Error ORA-26786

Question

Hi DBAs,
I have setup streams replication for 12 tables in 10.2.0.4 environments. Now at target site there are some columns where the user can change the data manually. Values of some columns in the destination table row do not match the old values of the corresponding columns. For example table TEST has columns ColA, ColB, ColC and ColD and ColE. User can change some time values in ColD and sometime in ColE. So then I am getting the error.
ORA-26786: A row with key ("ColB") = (4a002832854665a7) exists but has conflicting column(s) "ColE" in table TEST ORA-01403: no data found
I dont want to correct the values first in target tables and then the change should go as there are more than 1000 messeges comming in one LCR. I search over the web and found DML handler can be used for this problem. If someone can point me to the example that would be great. Metalink Artical 265201.1 did not help much how can I have an DML error handler defined.
Thanks

Thank you!
But my question is why its happening?
Why i got async of LCR?
Please Guru help me!
Let me explain steb by stem how i configure streams
1) create standby for primary
DB01 - Primary
DB02 - Standby/Streams
2) create user and tbs
CONNECT SYS/sys@DB01 AS SYSDBA
CREATE TABLESPACE streams_tbs DATAFILE 'd:\Oracle11r2\base\oradata\DB01\streams_tbs.dbf' SIZE 25 M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
CREATE USER STRMADMIN IDENTIFIED BY sys DEFAULT TABLESPACE streams_tbs QUOTA UNLIMITED ON streams_tbs;
GRANT DBA TO STRMADMIN;
EXEC DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE(grantee=> 'STRMADMIN',grant_privileges => TRUE);
exec DBMS_STREAMS_AUTH.GRANT_REMOTE_ADMIN_ACCESS(GRANTEE=>'STRMADMIN');
ALTER system SET GLOBAL_NAMES=TRUE scope=spfile;
ALTER system SET STREAMS_POOL_SIZE=50M scope=spfile;
alter system set GLOBAL_NAMES=TRUE scope=spfile;
3) create capture and propogantion on primary, set SCN
CONNECT strmadmin/sys@DB01
CREATE DATABASE LINK DB02 CONNECT TO strmadmin IDENTIFIED BY sys USING 'DB02';
exec dbms_streams_adm.set_up_queue(queue_table => 'CAPTURE_DB01',queue_name => 'CAPTURE_DB01',queue_user => 'strmadmin');
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_PROPAGATION_RULES (
SCHEMA_NAME => 'MY_SCHEAM',
STREAMS_NAME => 'DB01_TO_DB02',
SOURCE_QUEUE_NAME => 'CAPTURE_DB01',
DESTINATION_QUEUE_NAME => 'APPLY_TWDB2@DB02',
INCLUDE_DML => TRUE,
INCLUDE_DDL => TRUE,
SOURCE_DATABASE => 'DB01');
END;
EXEC DBMS_PROPAGATION_ADM.STOP_PROPAGATION(propagation_name => 'DB01_TO_DB02');
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES (
SCHEMA_NAME => 'MY_SCHEAM',
STREAMS_TYPE => 'CAPTURE',
STREAMS_NAME => 'CAPTURE_STREAM_DB01',
QUEUE_NAME => 'CAPTURE_DB01',
INCLUDE_DML => TRUE,
INCLUDE_DDL => TRUE,
INCLUSION_RULE => TRUE);
END;
EXEC DBMS_CAPTURE_ADM.PREPARE_SCHEMA_INSTANTIATION('MY_SCHEAM');
EXEC DBMS_CAPTURE_ADM.START_CAPTURE (CAPTURE_NAME => 'CAPTURE_STREAM_DB01');
EXEC DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN@DB02(SOURCE_SCHEMA_NAME => 'MY_SCHEAM',SOURCE_DATABASE_NAME => 'DB01',INSTANTIATION_SCN =>DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER);
-- switch current archive and stopd standby replication
ALTER SYSTEM ARCHIVE LOG CURRENT;
alter system set LOG_ARCHIVE_DEST_STATE_2=DEFER scope=both;
BEGIN
dbms_capture_adm.set_parameter(capture_name => 'CAPTURE_STREAM_DB01',parameter=> '_CHECKPOINT_FREQUENCY',VALUE=> '50');
dbms_capture_adm.alter_capture(capture_name => 'CAPTURE_STREAM_DB01',checkpoint_retention_time => 5);
dbms_capture_adm.set_parameter(capture_name => 'CAPTURE_STREAM_DB01',parameter=> 'PARALLELISM',VALUE=> '1');
dbms_capture_adm.set_parameter(capture_name => 'CAPTURE_STREAM_DB01',parameter=> '_SGA_SIZE',VALUE=> '50');
dbms_capture_adm.set_parameter(capture_name => 'CAPTURE_STREAM_DB01',parameter=> 'MESSAGE_TRACKING_FREQUENCY',VALUE=> '100000');
END;
4) activate standby
CONNECT SYS/SYSPWD@DB02 AS SYSDBA
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
ALTER DATABASE ACTIVATE STANDBY DATABASE;
ALTER DATABASE OPEN;
ALTER DATABASE RENAME GLOBAL_NAME TO DB02;
5) create apply on target db
CONNECT strmadmin/sys@DB02
EXEC DBMS_STREAMS_ADM.REMOVE_STREAMS_CONFIGURATION();
ALTER SYSTEM DISABLE RESTRICTED SESSION;
CREATE DATABASE LINK DB01 CONNECT TO strmadmin IDENTIFIED BY sys USING 'DB01';
exec dbms_streams_adm.set_up_queue(queue_table => 'APPLY_TWDB2', queue_name => 'APPLY_TWDB2', queue_user => 'strmadmin');
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES (
SCHEMA_NAME => 'MY_SCHEAM',
STREAMS_TYPE => 'APPLY',
STREAMS_NAME => 'APPLY_STREAM_TWDB2',
QUEUE_NAME => 'APPLY_TWDB2',
INCLUDE_DML => TRUE,
INCLUDE_DDL => TRUE,
SOURCE_DATABASE => 'DB01');
END;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'MY_SCHEAM.TABLE1',
streams_type => 'APPLY',
streams_name => 'APPLY_STREAM_TWDB2',
queue_name => 'APPLY_TWDB2',
include_dml => true,
include_ddl => true,
source_database => 'DB01',
inclusion_rule => false);
END;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'MY_SCHEAM.TABLE1',
streams_type => 'APPLY',
streams_name => 'APPLY_STREAM_TWDB2',
queue_name => 'APPLY_TWDB2',
include_dml => true,
include_ddl => true,
source_database => 'DB01',
inclusion_rule => false);
END;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'MY_SCHEAM.TABLE1',
streams_type => 'APPLY',
streams_name => 'APPLY_STREAM_TWDB2',
queue_name => 'APPLY_TWDB2',
include_dml => true,
include_ddl => true,
source_database => 'DB01',
inclusion_rule => false);
END;
begin
dbms_apply_adm.set_parameter(
apply_name => 'APPLY_STREAM_TWDB2',
parameter => 'disable_on_error',
value => 'N');
end;
then start propogation and apply proccess.
may be something wrong?
