Oracle Streams setup for multiple schemas in a same database

Question

We are on 11.1.0.7 and will be using Oracle 11g Streams that will replicate the data real-time for two schemas between the source and target set of schemas with in the same database. We will be doing DDL as well as DML replication.
I created the following plan and want your inputs. After implementing this, I created a table in SCOTT but it's get replicated to RPT_SCOTT later I tried inserting a row in the table created under SCOTT but that too didn't get replicated to RPT_SCOTT.
Here are the steps that I used to set up my STREAMS -
Database Instance:     TESTDB
Schemas:
     Source:          SCOTT
               HR
     Target:          RPT_SCOTT
               RPT_HR
Configuring Streams:
1.     Database is in Archive log mode
2.     Set up the Streams administrator.
create user STRMADMIN identified by STRMADMIN default tablespace USERS temporary tablespace temp;
grant resource, dba, AQ_ADMINISTRATOR_ROLE to STRMADMIN;
BEGIN
DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE(
grantee => 'STRMADMIN',
grant_privileges => TRUE);
END;
3.     Set up Streams queues
CONNECT STRMADMIN/****
BEGIN
DBMS_STREAMS_ADM.SET_UP_QUEUE(
queue_name => 'STREAMS_QUEUE',
queue_table => 'STREAMS_QUETAB',
queue_user => 'STRMADMIN');
END;
4.     Add the Apply rule
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name      => 'RPT_SCOTT',
streams_type     => 'APPLY',
streams_name     => 'APPLY_CC_STREAM',
queue_name          => 'STRMADMIN.STREAMS_QUEUE',
include_dml     => true,
include_ddl     => true,
inclusion_rule     => true,
source_database     => 'TESTDB');
END;
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name      => 'RPT_HR',
streams_type     => 'APPLY',
streams_name     => 'APPLY_AB_STREAM',
queue_name          => 'STRMADMIN.STREAMS_QUEUE',
include_dml     => true,
include_ddl     => true,
inclusion_rule     => true,
source_database     => 'TESTDB');
END;
BEGIN
DBMS_APPLY_ADM.ALTER_APPLY(
apply_name     => 'APPLY_CC_STREAM',
apply_user     => 'STRMADMIN');
END;
BEGIN
DBMS_APPLY_ADM.ALTER_APPLY(
apply_name     => 'APPLY_AB_STREAM',
apply_user     => 'STRMADMIN');
END;
5.     Add the Capture Rule
CONNECT STRMADMIN/*****
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name     => 'SCOTT',
streams_type     => 'CAPTURE',
streams_name     => 'CAPTURE_CC_STREAM',
queue_name          => 'STRMADMIN.STREAMS_QUEUE',
include_dml     => true,
include_ddl     => true,
inclusion_rule     => true,
source_database     => 'TESTDB');
END;
BEGIN
DBMS_STREAMS_ADM.ADD_SCHEMA_RULES(
schema_name     => 'HR',
streams_type     => 'CAPTURE',
streams_name     => 'CAPTURE_AB_STREAM',
queue_name          => 'STRMADMIN.STREAMS_QUEUE',
include_dml     => true,
include_ddl     => true,
inclusion_rule     => true,
source_database     => 'TESTDB');
END;
6.     Set the instantiation system change number (SCN)
CONNECT STRMADMIN/******
DECLARE
source_scn NUMBER;
BEGIN
source_scn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN (
source_schema_name => 'SCOTT',
source_database_name => 'TESTDB',
instantiation_scn => source_scn);
END;
7.     Start the Apply
CONNECT STRMADMIN/******
BEGIN
DBMS_APPLY_ADM.START_APPLY('APPLY_CC_STREAM');
END;
BEGIN
DBMS_APPLY_ADM.START_APPLY('APPLY_AB_STREAM');
END;
8.     Start the Capture
CONNECT STRMADMIN/******
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE('CAPTURE_CC_STREAM');
END;
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE('CAPTURE_AB_STREAM');
END;

Answer 1

If I understand from your code, you want to do this on the same DB :
SCOTT --> RPT_SCOTT
HR  --> RPT_HRSo there is a schema transformation, where is it coded ?
General info : http://download.oracle.com/docs/cd/B28359_01/server.111/b28321/strms_transform.htm
More specific on schema rename : http://download.oracle.com/docs/cd/B28359_01/server.111/b28321/strms_mtransform.htm#CHDGDHDE
Next : where are the initialisation of both capture schema ?
Missing :
execute DBMS_CAPTURE_ADM.PREPARE_SCHEMA_INSTANTIATION( schema_name          => 'scott'');
execute DBMS_CAPTURE_ADM.PREPARE_SCHEMA_INSTANTIATION( schema_name          => 'HR'');This tell Streams from where to capture the SCN.
Also there is an (WRONG) instantiation of SCOTT for the apply, which tells the apply to consider as valuable candidate all LCR after source_scn,
but where is the code or RPT_HR. Alas, you put for the APPLY target schema 'SCOTT' while it should have been 'RPT_SCOTT'.
the fact that is correct or false depends where you put the schema transformation. If you put the transformation at apply time then use the SOURCE schema name (SCOTT, HR) for the LCR will contains their name. If you put the transformation at capture time, then put target schema name for the LCR will contain their name (RPT_HR,RPT_SCOTT).
Let's say you put the schema transformation at capture time then
Missing:
DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN (
source_schema_name => 'RPT_HR',
source_database_name => 'TESTDB',
instantiation_scn => source_scn);If you attache the transformation on the apply process then the code is :
DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN (
source_schema_name => 'HR',
source_database_name => 'TESTDB',
instantiation_scn => source_scn);And this is useless:
-- useless code
BEGIN
DBMS_APPLY_ADM.ALTER_APPLY(
apply_name => 'APPLY_CC_STREAM',
apply_user => 'STRMADMIN');
END;
BEGIN
DBMS_APPLY_ADM.ALTER_APPLY(
apply_name => 'APPLY_AB_STREAM',
apply_user => 'STRMADMIN');
END;
/Last : You are using the same queue for 2 separated capture/apply transformation.
Do yourself a favor and give each couple capture/tranform/apply its own queue.
