Connected.
declare
    tables dbms_utility.uncl_array;
begin
    tables(1) := 'SCOTT.DEPT';
    tables(2) := 'SCOTT.EMP';

        instantiation => DBMS_STREAMS_ADM.INSTANTIATION_TABLE
    );
end;

job finished
PL/SQL procedure successfully completed.
4、表空间级别streams复制 

--在源数据库中创建 目录对象
create directory example_ts_dir as '/u01/oradata/DBXA';
Directory created.

grant read on directory example_ts_dir to strmadmin;
Grant succeeded

--在目标数据库中创建目录对象
create directory example_ts_dir as '/u02/app/oradata/DBXB';
Directory created.

--使用maintain_simple_tts过程创建表空间streams复制
connect strmadmin/strmadmin@DBXA.WORLD
Connected.
begin
    dbms_streams_adm.maintain_simple_tts(
        tablespace_name => 'EXAMPLE_TS',
        source_directory_object => 'STREAMS_DP_DIR',
        source_database => 'DBXA.WORLD',

        script_name => 'cr_maintain_simple_tts_uni.sql',
        script_directory_object => 'STREAMS_DP_DIR',
        bi_directional => FALSE
    );
end;
/
PL/SQL procedure successfully completed.

--使用MAINTAIN_TTS过程创建表空间streams复制

5、使用MAINTAIN存储过程配置下游捕获进程

--存储过程运行在目标数据库DBXB.WORKD中
--不需要传播进程，如果指定了传播进程也不会创建
--捕获进程和应用进程的队列名和队列表名一样
connect strmadmin/strmadmin@DBXB.WORLD
Connected.
declare
    schemas dbms_utility.uncl_array;
begin
    schemas(1) := 'SCOTT';
    schemas(2) := 'HR';

    dbms_streams_adm.maintain_schemas (
        schema_names => schemas,
        source_database => 'DBXA.WORLD',
        source_directory_object => 'STREAMS_DP_DIR',
        destination_database => 'DBXB.WORLD',
        destination_directory_object => 'STREAMS_DP_DIR',
        capture_name => 'DBXA_CAP',
        capture_queue_name => 'DBXA_CAP_Q',
        capture_queue_table => 'DBXA_CAP_Q_T',
        propagation_name => 'DBXA_TO_DBXB_PROP',
        apply_name => 'DBXA_APP',
        apply_queue_name => 'DBXA_CAP_Q',
        apply_queue_table => 'DBXA_CAP_Q_T',
        dump_file_name => NULL,
        log_file => NULL,
        bi_directional => FALSE,
        include_ddl => TRUE,
        perform_actions => TRUE
    );
end;

--配置从数据库DBXA.WORLD到DBXB.WORLD的streams复制的方法
--存储过程运行在DBXB.WORLD数据库中
--传播定义从DBXB.WORLD到DBXC.WORLD
--捕获进程和应用进程的队列名和队列表名不同
connect strmadmin/strmadmin@DBXB.WORLD
Connected.
declare
    schemas dbms_utility.uncl_array;
begin
    schemas(1) := 'SCOTT';
    schemas(2) := 'HR';

    dbms_streams_adm.maintain_schemas (
        schema_names => schemas,
        source_database => 'DBXA.WORLD',

6、创建视图来查看streams 存储过程的状态和进度
--主要是基于DBA_RECOVERABLE_SCRIPT视图和DBA_RECOVERABLE_SCRIPT_BLOCKS视图创建
connect sys as sysdba
set long 100000000
create or replace view streams_build_status
as
    select to_char(rs.creation_time,'HH24:Mi:SS MM/DD/YY') CREATE_DATE,
        rs.status,
        rs.done_block_num||' of ' ||rs.total_blocks ||' Steps Completed' PROGRESS,
        to_char(to_number(sysdate-rs.creation_time)*86400,9999.99) ELAPSED_SECONDS,
        substr(rsb.forward_block,1,5000) CURRENT_STEP,
        rs.invoking_package||'.'||rs.invoking_procedure PROCEDURE,
        rs.script_id
    from dba_recoverable_script rs,
            dba_recoverable_script_blocks rsb
    where rs.script_id = rsb.script_id
    and rsb.block_num = rs.done_block_num + 1;
    
create public synonym streams_build_status for streams_build_status;
grant select on streams_build_status to public;

--查询进度信息（存储过程当前正在执行、一共有14个过程块已经完成13个、已经运行了276秒）
select status,
    progress,
    elapsed_seconds elapsed,
    script_id

    dbms_capture_adm.start_capture(
        capture_name => '"DBXA$CAP"'
    );
EXCEPTION WHEN OTHERS THEN
    IF sqlcode = -26666 THEN NULL; -- CAPTURE process already running
    ELSE RAISE;
    END IF;
END;

--提取脚本及过程块

set pages 1000
spool maintain_script.sql
    select '-- Block: ' || block_num,
        forward_block
    from dba_recoverable_script_blocks
    where script_id = '7CC97F3B9169704BE040A8C014006E63'
    order by block_num;

12、还有以下几种配置策略（P228）

1)从单个源到多个目标数据库

2)使用队列转发的复制

3)使用应用转发的复制

4)辐射类型复制

5)点对点复制
