数据库：sc_source 和 sc_dest
要求：将sc_source中的product用户下的所有对象都复制到sc_dest上去
一、准备工作：
1.1 将sc_source和sc_dest数据库都置于归档模式
1.2 如果有些表没有主键，为保证复制的准确性，需要在源数据库（sc_source）上配置辅助日志
alter database add supplemental log data(primary key,unique) columns;
1.3 源，目标库设置一些参数
job_queue_processes=4
aq_tm_processes=4
global_names=true
1.4 创建流复制的管理用户源，目标库都需要配置
create tablespace streams_tbs datafile '/Oracle/oradata/streams_tbs01.dbf' size 1024M;
create user strmadmin identified by strmadmin default tablespace streams_tbs quota unlimited on streams_tbs;
grant dba,select_catalog_role to strmadmin;
1.5 创建数据库连接
sc_source：
create database link sc_dest.net connect to strmadmin identified by strmadmin using 'sc_dest';
sc_dest:
create database link sc_source.net connect to strmadmin identified by strmadmin using 'sc_source';
二，开始配置streams
sc_source
-----------------------------------
配置捕获进程队列
begin
dbms_streams_adm.set_up_queue(
queue_table => 'capture_scstab',
queue_name => 'capture_scs',
queue_user => 'strmadmin');
end;
/
sc_dest
-----------------------------------
配置应用进程队列
begin
dbms_streams_adm.set_up_queue(
queue_table => 'apply_scdtab',
queue_name => 'apply_scd',
queue_user => 'strmadmin');
end;
/
sc_source
-----------------------------------
配置捕获进程
begin
dbms_streams_adm.add_schema_rules (
schema_name => 'product',
streams_type => 'capture',
streams_name => 'capture_scstrm',
queue_name => 'capture_scs',
include_dml => true,
include_ddl => true,
inclusion_rule => true);
end;
/
配置传播进程
begin
dbms_streams_adm.add_schema_propagation_rules (
schema_name => 'product',
streams_name => 'pro_source_to_dest',
source_queue_name => 'capture_scs',
destination_queue_name => 'apply_scd@sc_dest.net',
include_dml => true,
include_ddl => true,
source_database => 'sc_source.net');
end;
/
sc_dest
--------------------------------------------------------
配置应用进程
begin
dbms_streams_adm.add_schema_rules (
schema_name => 'product',
streams_type => 'apply',
streams_name => 'apply_scdtrm',
queue_name => 'apply_scd',
include_dml => true,
include_ddl => true,
source_database => 'sc_source.net');
end;
/
