Dear All,

Oracle Version: 10.1.0.2.0
Operating System: WIndows Server 2003

I am testing Oracle Replication by using the following link
http://www.oracle-base.com/articles/9i/Streams9i.php

i had deployed all the steps mentioned on the link
but after inserting some rows in source table

conn scott/tiger@TESTWLL (Source DB)
INSERT INTO dept (deptno, dname, loc) VALUES (99, 'Test Dept', 'UK')
INSERT INTO dept (deptno, dname, loc) VALUES (50, 'TEST', 'LHR')

SQL> select * from dept;

DEPTNO DNAME LOC
---------- -------------- -------------
10 ACCOUNTING NEW YORK
20 RESEARCH DALLAS
30 SALES CHICAGO
40 OPERATIONS BOSTON
50 TEST LHR
99 Test Dept UK

6 rows selected.

SQL> conn scott/tiger@testdb (target DB)
Connected.
SQL> select * from dept;

DEPTNO DNAME LOC
---------- -------------- -------------
10 ACCOUNTING NEW YORK
20 RESEARCH DALLAS
30 SALES CHICAGO
40 OPERATIONS BOSTON

I didn't miss even a single step but its not working for me
can u please give me any suggestion in this regard?
where i should have to recheck now?


thanx in advance

Diagnosis your stream environment . Look at status in dba_capture, dba_propagation and dba_apply and find out where is the problem?

I saw that link . That like is for 9i and you have version 10g. Why you look for lower one configuration? If you have extra benefit of higher one don't go to downward.

Dear All,

I had successfully implement Replication with Streams for oracle 9i using the link

http://www.oracle-base.com/articles/9i/Streams9i.php

i think its a uni-Replication ,
e.g
if i update replicated table (EMP) at site dba1 then it will update EMP Table at site dba2 but not vice versa
if i had a TABLE EMP at both sides with same structure and i need if updation is made at dba2 then it'll automatically applied at dba2 and if updation is done at dba2 then it'll automatically applied at dba1
i know i can implement this by using multimaster Replication but i want to know if it is possible with Streams
if its possible then which steps should i have to add to accomplish the task?
thanx in advance

Congrats .

By streams bidirectional replication is possible.

Dear MR.Arju

may i ask u where i should have add this parameter
bi_directional=>true to achieve 2-way Replication?

did u see the link which i m using for Replication,i want to ask u where should i have to make modifications to accomplish?


I hope u won't mind it
thanx

Dear MR.Arju

I had configured the Uni-Replication using Streams with following Steps

I had two databases DBA1 and DBA2
DBA1 as source and DBA2 as destination


Step1 Stream Administrator Setup
-------------------------------------------
CONN sys/password@DBA1 AS SYSDBA

CREATE USER strmadmin IDENTIFIED BY strmadminpw
DEFAULT TABLESPACE users QUOTA UNLIMITED ON users;

GRANT CONNECT, RESOURCE, SELECT_CATALOG_ROLE TO strmadmin;

GRANT EXECUTE ON DBMS_AQADM TO strmadmin;
GRANT EXECUTE ON DBMS_CAPTURE_ADM TO strmadmin;
GRANT EXECUTE ON DBMS_PROPAGATION_ADM TO strmadmin;
GRANT EXECUTE ON DBMS_STREAMS_ADM TO strmadmin;
GRANT EXECUTE ON DBMS_APPLY_ADM TO strmadmin;
GRANT EXECUTE ON DBMS_FLASHBACK TO strmadmin;

BEGIN
DBMS_RULE_ADM.GRANT_SYSTEM_PRIVILEGE(
privilege => DBMS_RULE_ADM.CREATE_RULE_SET_OBJ,
grantee => 'strmadmin',
grant_option => FALSE);
END;
/

BEGIN
DBMS_RULE_ADM.GRANT_SYSTEM_PRIVILEGE(
privilege => DBMS_RULE_ADM.CREATE_RULE_OBJ,
grantee => 'strmadmin',
grant_option => FALSE);
END;
/

CONNECT strmadmin/strmadminpw@DBA1
EXEC DBMS_STREAMS_ADM.SET_UP_QUEUE();

CREATE DATABASE LINK dba2 CONNECT TO strmadmin IDENTIFIED BY strmadminpw USING 'DBA2';

GRANT ALL ON scott.dept TO strmadmin;
Note:The above mentioned All steps are also applied DBA2
--------------------------------------------------------------
Step2: LogMinor Tablespace Setup at Source DB DBA1

CONN sys/password@DBA1 AS SYSDBA

CREATE TABLESPACE logmnr_ts DATAFILE '/u01/app/oracle/oradata/DBA1/logmnr01.dbf'
SIZE 25 M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;

EXECUTE DBMS_LOGMNR_D.SET_TABLESPACE('logmnr_ts');

---------------------------------------------------

Step3:Supplemental Logging at Source DB DBA1
CONN sys/password@DBA1 AS SYSDBA
ALTER TABLE scott.dept ADD SUPPLEMENTAL LOG GROUP log_group_dept_pk (deptno) ALWAYS;

--------------------------------------------------

Step4:Configure Propagation Process at Source DB DBA1

CONNECT strmadmin/strmadminpw@DBA1
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES(
table_name => 'scott.dept',
streams_name => 'dba1_to_dba2',
source_queue_name => 'strmadmin.streams_queue',
destination_queue_name => 'strmadmin.streams_queue@dba2',
include_dml => true,
include_ddl => true,
source_database => 'dba1');
END;
/

-----------------------------------------------------
Step5: Configure Capture Process on DBA1

CONNECT strmadmin/strmadminpw@DBA1
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'scott.dept',
streams_type => 'capture',
streams_name => 'capture_simp',
queue_name => 'strmadmin.streams_queue',
include_dml => true,
include_ddl => true);
END;
/

-------------------------------------------------------
Step6: Configure Instantiation SCN on DBA1 (Source DB)

CONNECT strmadmin/strmadminpw@dba1
DECLARE
v_scn NUMBER;
BEGIN
v_scn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_APPLY_ADM.SET_TABLE_INSTANTIATION_SCN@DBA2(
source_object_name => 'scott.dept',
source_database_name => 'dba1',
instantiation_scn => v_scn);
END;
/
-------------------------------------------------
Step7:Configure Apply Process at Destination DB DBA2

CONNECT strmadmin/strmadminpw@DBA2
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'scott.dept',
streams_type => 'apply',
streams_name => 'apply_simp',
queue_name => 'strmadmin.streams_queue',
include_dml => true,
include_ddl => true,
source_database => 'dba1');
END;
/

---------------------------------------------
Step8 Start Apply Process at DEst DB (DBA2)

CONNECT strmadmin/strmadminpw@DBA2
BEGIN
DBMS_APPLY_ADM.SET_PARAMETER(
apply_name => 'apply_simp',
parameter => 'disable_on_error',
value => 'n');

DBMS_APPLY_ADM.START_APPLY(
apply_name => 'apply_simp');
END;
/

-----------------------------------------------
Step9 :Start Capture Process at Source DB DBA1

CONNECT strmadmin/strmadminpw@DBA1
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE(
capture_name => 'capture_simp');
END;
/

---------------------------------------------

Dear All

These are the basic Steps which i had adopt to implement Replication
This is basically a uni-direction Replication and i came to know that we can configure bi-direction Replication
By Looking at above mentioned steps ,can anybody suggest where i should have to make changes to accomplish the Bidirection Replication???????

i m working on this for the last 3-4 days but unable to do so
Arju had given the suggestion
The parameter bi_directional=>true maintain this
But i don't have an exact idea where i should have to add this
can anybody help me in this regard?

Thanx in advance

It sounds like lack of privilege.
