4、表空間級別streams複製

--在源數據庫中創建 目錄對象
create directory example_ts_dir as '/u01/oradata/DBXA';
Directory created.

grant read on directory example_ts_dir to strmadmin;
Grant succeeded

--在目標數據庫中創建目錄對象
create directory example_ts_dir as '/u02/app/oradata/DBXB';
Directory created.

--使用maintain_simple_tts過程創建表空間streams複製

5、使用MAINTAIN存儲過程配置下游捕獲進程

--存儲過程運行在目標數據庫DBXB.WORKD中
--不需要傳播進程，如果指定了傳播進程也不會創建
--捕獲進程和應用進程的隊列名和隊列表名一樣
connect strmadmin/[email protected]
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',

6、創建視圖來查看streams 存儲過程的狀態和進度

--主要是基於DBA_RECOVERABLE_SCRIPT視圖和DBA_RECOVERABLE_SCRIPT_BLOCKS視圖創建
connect sys as sysdba
set long 100000000

        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;

--查詢進度信息（存儲過程當前正在執行、一共有14個過程塊已經完成13個、已經運行了276秒）
select status,
    progress,

12、還有以下幾種配置策略（P228）

1)從單個源到多個目標數據庫

2)使用隊列轉發的複製

3)使用應用轉發的複製

4)輻射類型複製

5)點對點複製
