一.Single stream #9R2和10g均可設定
1.主從庫必須起動歸檔
主庫可以基於Database級別或Table級別，啟用追加日誌（Supplemental Log）。在建立根據Schema粒度進行復制的Oracle Stream 環境中，如果確認Schema 下所有Table 都有合理的主鍵(Primary Key)，則不再需要啟用追加日誌。
#啟用Database 追加日誌
alter database add supplemental log data;
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY, UNIQUE INDEX, FOREIGN KEY) COLUMNS;
#啟用Table追加日誌
alter table add supplement log group log_group_name(table_column_name) always;

2.主從建streams admin 表空間
CREATE TABLESPACE streams_tbs DATAFILE '/u01/app/oracle/oradata/sid/streams_tbs.dbf' size 50M reuse autoextend on maxsize unlimited;

3.主從建streams user
   CREATE USER strmadmin IDENTIFIED BY strmadmin DEFAULT TABLESPACE streams_tbs temporary tablespace temp QUOTA UNLIMITED ON streams_tbs;
grant connect,resource,dba,aq_administrator_role to strmadmin;
BEGIN
    DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE(
       grantee          => 'strmadmin',
       grant_privileges => true);
END;

4.主從建立DB link #propagate messages from a source queue at a database to a destination queue
connect
create public database link qhrac connect to strmadmin identified by strmadmin using 'qhrac';
   connect
create public database link qhadb connect to strmadmin identified by strmadmin using 'qhrac';

5.主庫引數修改,並在歸檔下
alter system set aq_tm_processes=2 scope=both;    //不要設定成0或者10, 這樣做可能禁用佇列監測處理和影響流池記憶體利用率
alter system set global_names=true scope=both;
alter system set job_queue_processes=10 scope=both;   //建議的最低值為4,定義傳播程式數
alter system set parallel_max_servers=20 scope=both; //並行執行可用的最大程式數量
alter system set undo_retention=3600 scope=both; //資料提交後至少保留的秒數.
alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS' scope=spfile; //時間格式
alter system set streams_pool_size=200M scope=spfile; //沒有捕獲程式無須配置此處
alter system set open_links=4 scope=spfile;    //資料庫連線數.DB_LINK

6.主庫create queue
connect strmadmin/strmadmin
begin
dbms_streams_adm.set_up_queue(
queue_table => 'qhadb_queue_table',
queue_name => 'qhadb_queue');
end;

7.從庫create queue
connect strmadmin/strmadmin
begin
dbms_streams_adm.set_up_queue(
queue_table => 'qhrac_queue_table',
queue_name => 'qhrac_queue');
end;

8.主庫建立捕獲程式
connect strmadmin/strmadmin
begin
dbms_streams_adm.add_schema_rules(
schema_name => 'hs_his',
streams_type => 'capture',
streams_name => 'capture_qhadb',
queue_name => 'strmadmin.qhadb_queue',
include_dml => true,
include_ddl => true,
include_tagged_lcr => true,
source_database => null,
inclusion_rule => true);
end;

9.例項化複製資料庫
主資料庫exp -> 從資料庫
impdp system/oracle network_link=qhadb schemas=hs_his

connect strmadmin/strmadmin
DECLARE
iscn NUMBER;
BEGIN
iscn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
(
source_schema_name    => 'hs_his',
source_database_name => 'qhadb',
instantiation_scn     => iscn,
recursive             => true);
END;

10.主庫建立傳播程式##queue_to_queue =ture automatic failover when the destination queue is a buffered queue in a Real Application Clusters (RAC) database
connect strmadmin/strmadmin
begin
dbms_streams_adm.add_schema_propagation_rules(
schema_name => 'hs_his',
streams_name => 'qhadb_to_qhrac',
source_queue_name => 'strmadmin.qhadb_queue',
destination_queue_name => ,
include_dml => true,
include_ddl => true,
include_tagged_lcr => false,
source_database => 'qhadb',
inclusion_rule => true,
queue_to_queue => true);
end;
修改propagation休眠時間為0，表示實時傳播LCR
begin
dbms_aqadm.alter_propagation_schedule(
queue_name => 'qhadb_queue',
destination => 'qhrac',
latency => 0);
end;

11.從庫建立應用程式
connect strmadmin/strmadmin
begin
dbms_streams_adm.add_schema_rules(
schema_name => 'hs_his',
streams_type => 'apply',
streams_name => 'apply_qhrac',
queue_name => 'strmadmin.qhrac_queue',
include_dml => true,
include_ddl => true,
include_tagged_lcr => true,
source_database => 'qhadb',
inclusion_rule => true);
end;

12.從庫啟動Apply程式
CONNECT strmadmin/strmadmin
BEGIN
    DBMS_APPLY_ADM.SET_PARAMETER(
    apply_name => 'apply_qhrac',
    parameter   => 'disable_on_error',
    value       => 'n');
begin
dbms_apply_adm.start_apply(
apply_name => 'apply_qhrac');
end;
停止
connect strmadmin/strmadmin
begin
dbms_apply_adm.stop_apply(
apply_name => 'apply_qhrac');
end;

13.主庫啟動Capture程式
connect strmadmin/strmadmin
begin
dbms_capture_adm.start_capture(
capture_name => 'capture_qhadb');
end;
停止
connect strmadmin/strmadmin
begin
dbms_capture_adm.stop_capture(
capture_name => 'capture_qhadb');
end;

14.清除Stream配置資訊(先要停),主從庫,10.2.0.3以前會報錯Bug 5640593
connect strmadmin/strmadmin
exec DBMS_STREAMS_ADM.remove_streams_configuration();

15.管理
   檢視道捕捉(Capture)程式
   SELECT CAPTURE_NAME,QUEUE_NAME,RULE_SET_NAME,NEGATIVE_RULE_SET_NAME,START_SCN,STATUS,CAPTURE_TYPE FROM DBA_CAPTURE;
    STATUS：ENABLED，表示Capture程式執行正常；
         DISABLED，表示Capture程式處於停止狀態，只需重新啟動即可；
         ABORTED，表示Capture 程式非正常停止，查詢相應的ERROR_NUMBER、ERROR_MESSAGE 列可以得到詳細的資訊；同時，Oracle會在跟蹤檔案中記錄該資訊。

   select sid,serial#,capture_name,startup_time,state,state_changed_time from v$streams_capture
    state： INITIALIZING-開始
WAITING FOR DICTIONARY REDO ---等待包含關係first scn的字典的redo log 檔案被加進捕獲程式會話。直到所有包含字典的redo log檔案被加，捕獲程式才可以開始掃描redo log檔案。
   CAPTURING CHANGES           ---掃描redo log。
   CREATING LCR      ---把改變格式化成LCR。
   ENQUEUING MESSAGE           ---把滿足規則的LCR塞進捕獲佇列。
   PAUSED FOR FLOW CONTROL     ---不能夠塞LCR進佇列。可能由於傳播或應用程式消化訊息慢過捕獲程式建立訊息。當傳播包或應用程式遠遠落後或不可用時，它可以提醒，減少遺漏捕獲的資訊。
   select * from ALL_CAPTURE_PREPARED_SCHEMAS;

   查Captured LCR是否有傳播GAP？
   SELECT CAPTURE_NAME, QUEUE_NAME, STATUS, CAPTURED_SCN,APPLIED_SCN FROM DBA_CAPTURE;
    如果APPLIED_SCN 小於CAPTURED_SCN，則表示在主資料庫一端，要麼LCR 沒有被dequeue，要麼Propagation程式尚未傳播到從資料庫一端。

   查Appy程式
   SELECT apply_name, apply_captured, status,error_message FROM dba_apply;
    STATUS：ENABLED，表示Apply程式執行正常；
DISABLED，表示Apply程式處於停止狀態，只需重新啟動即可；
ABORTED，表示Apply 程式非正常停止，查詢相應的ERROR_NUMBER、ERROR_MESSAGE 列可以得到詳細的資訊；同時，可以查詢DBA_APPLY_ERROR檢視，瞭解詳細的Apply錯誤資訊。

   select apply_name,queue_name,message_number,error_number,error_message,message_count,error_creation_time from DBA_APPLY_ERROR;
   v$streams_apply_reader
   v$streams_apply_coordinator
   v$streams_apply_server

16.從庫和主庫之間時間間隔跟效能及其它情況有關，包括capture mining logfile的速度，propagation的間隔(預設3秒)及傳輸時間,apply log的速度

二.example
在Oracle Stream Replication提供的庫中，有一個SubSet的概念，可以把一個Table的資料做一個Horizontal的Partition，也就是說可以水平分割Table中的資料，
來實現資料的同步。但是在某些應用場合，存在這樣的需求，就是一個Table中的一些欄位Change的頻率相當頻繁，而這些Column是特定於本地的AS的，
A Site的這些Column的值對於B Site的AS來說，無關緊要。因為，在應用上通常，B Site的AS會重新設定這些Column的值。
如果Stream replication對Replication不加以區分的話，那這些changes很頻繁的Column會給整個系統帶來很大的效能影響，
特別是在3個Site的相互Replication上。
複製或同步部分欄位，而不是整個表欄位, 實現的方法是採用Rule-base Transformation，而且是針對Capture Process，因為如果不從Source DB源頭做的話，透過大量的Propagation和Apply，對系統的效能影響和不做是沒太大的區別的。
以2個Site的Replication為例：db1 --&gt db2
1.首先，建立相應的Capture、Apply和Propagation，以schema的級別來Setup，而且建立起來的Rule都是屬於Positive的，不是Negative.
   rem ;set up the apply queues
   rem ;*************************************************************************
   begin
    dbms_streams_adm.set_up_queue(
        queue_table    => 'apply_db2tab',
        queue_name    => 'apply_db2',
        queue_user    => 'strmadmin');
   end;
   /
   rem ;set up the capture queue
   rem ;*************************************************************************
   begin
    dbms_streams_adm.set_up_queue(
        queue_table    => 'capture_db1tab',
        queue_name    => 'capture_db1',
        queue_user    => 'strmadmin');
   end;
   /
   rem ;set up the apply process
   rem ;*************************************************************************
   begin
    dbms_streams_adm.add_schema_rules (
          schema_name => 'bartholo',
          streams_type => 'apply',
          streams_name => 'apply_src_db2',
          queue_name => 'apply_db2',
          include_dml => true,
          include_ddl => true,
          source_database => 'db2.world');
   end;
/
rem ;set up the capture process
rem ;*************************************************************************
begin
    dbms_streams_adm.add_schema_rules (
          schema_name => 'bartholo',
          streams_type => 'capture',
          streams_name => 'capture_db1strm',
          queue_name => 'capture_db1',
          include_dml => true,
          include_ddl => true,
          inclusion_rule => true);
end;
/
rem ;set up the propagation process
rem ;*************************************************************************
begin
    dbms_streams_adm.add_schema_propagation_rules (
      schema_name   => 'bartholo',
      streams_name   => 'prop_db1_to_db2',
      source_queue_name => 'capture_db1',
      destination_queue_name => ,
      include_dml   => true,
      include_ddl   => true,
      source_database => 'db1.world');
end;
/
2.這裡我的Stream User是strmadmin,已經給以了DBA的許可權。這部要做的是實現一個Transform. Function.
   這裡假設我們的Table是這樣定義的：tab1(col1, col2, col3)其中col3的Update操作不做Replication.達到的目標是：不管Source Site對Col3做任何的Update修改，在目的站點都是看不見，保持不變。
CREATE OR REPLACE PACKAGE strmpkg as
     function transform_capture(in_any IN SYS.AnyData) RETURN SYS.AnyData;
END strmpkg;
/
CREATE OR REPLACE PACKAGE BODY strmpkg as
FUNCTION transform_capture(in_any IN SYS.AnyData)
RETURN SYS.AnyData
IS
lcr        SYS.LCR$_ROW_RECORD;
rc        NUMBER;
ob_owner    VARCHAR2(30);
ob_name    VARCHAR2(30);
cmd        VARCHAR2(10);
newvalue_anydata SYS.AnyData;
oldvalue_anydata SYS.Anydata;
BEGIN
IF in_any.GETTYPENAME='SYS.LCR$_ROW_RECORD' THEN
    -- Put the row LCR into lcr
    rc := in_any.GETOBJECT(lcr);

    -- Get the object owner and name
    ob_owner := lcr.GET_OBJECT_OWNER();
    ob_name := lcr.GET_OBJECT_NAME();
    cmd    := lcr.GET_COMMAND_TYPE();
    --只對bartholo這個schema 和 Update的操作進行轉換，其它的放行
    IF ob_owner = 'bartholo' AND cmd = 'UPDATE' THEN
      IF ob_name = 'tab1' THEN
        -- Remove the specified column in the LCR
        newvalue_anydata := lcr.GET_VALUE('new','col3');
        oldvalue_anydata := lcr.GET_VALUE('old','col3');
        IF ( (newvalue_anydata IS NOT NULL) OR (oldvalue_anydata IS NOT NULL) )
        THEN
          --just only the column existed, u can delte the column
          lcr.DELETE_COLUMN(column_name => 'col3');
        END IF;
      END IF;
    END IF;
    RETURN SYS.ANYDATA.CONVERTOBJECT(lcr);
END IF;
RETURN in_any;
END transform_capture;
END strmpkg;
/
3.把這個Transform. Function和Capture的DML Rule關聯起來。
DECLARE
capture_dml_rule VARCHAR2(30);
BEGIN
SELECT rule_name INTO capture_dml_rule FROM sys.streams$_rules
WHERE streams_name='CAPTURE_DB1STRM' and rule_type = 1 AND ROWNUM = 1
ORDER BY rule_name DESC;
DBMS_STREAMS_ADM.set_rule_transform_function(
rule_name    => capture_dml_rule,
transform_function    => 'strmpkg.transform_capture');
END;
/
4.把Schema及其包含的物件在2站點上相互做個Instantiation.
DECLARE
iscn NUMBER;         -- Variable to hold instantiation SCN value
BEGIN
iscn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_OUTPUT.PUT_LINE('The SCN for db2 and db3: ' || iscn);
(
source_schema_name    => 'bartholo',
source_database_name => 'db1.world',
instantiation_scn     => iscn);
END;
/

5.啟動db2站點上的Apply, DB1上的Propagation和Capture。

三.一對多複製
一對多與一對一不同的就是，在源資料庫傳播的時候要向多個目標資料庫傳播，每個目標資料庫都要配置相應的應用程式
   db1--&gtdb2;db1--&gtdb3
1.引數修改(db1,db2,db3)
alter system set aq_tm_processes=4 scope=spfile;
alter system set global_names=true scope=spfile;
alter system set job_queue_processes=8 scope=spfile;
alter system set log_parallelism=1 scope=spfile;
alter system set global_names=true scope=spfile;
2.建立流管理員，並對其進行授權(db1,db2,db3)
CREATE USER strmadmin IDENTIFIED BY strmadmin DEFAULT TABLESPACE users QUOTA UNLIMITED ON users;
GRANT DBA, 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;
GRANT ALL ON scott.dept 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;
/
3.建db link
db1:
create public database link db2 connect to strmadmin identified by strmadmin using 'db2';
create public database link db3 connect to strmadmin identified by strmadmin using 'db3';
db2,db3:
create public database link db1 connect to strmadmin identified by strmadmin using 'db1';
4.建立LogMinor 表空間，並新增SUPPLEMENTAL 日誌 (db1)
conn /as sysdba
CREATE TABLESPACE logmnr_ts DATAFILE 'D:\oracle\product\10.2.0\oradata\orcl\logmnr01.dbf' SIZE 25 M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
EXECUTE DBMS_LOGMNR_D.SET_TABLESPACE('logmnr_ts');
#啟用Database 追加日誌
alter database add supplemental log data;
#啟用Table追加日誌
alter table *** add supplement log group log_group_name(table_column_name) always;
5.配置傳播程式(db1)
conn
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES(
table_name => 'scott.dept',
streams_name => 'db1_to_db2',
source_queue_name => 'strmadmin.streams_queue',
destination_queue_name => ,
include_dml => true,
include_ddl => true,
source_database => 'db1');
END;
/
備註：引數destination_queue_name中的db2是建立的指向db2資料庫的db link,source_database的值必須是目標資料庫指向源資料庫的db link;
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES(
table_name => 'scott.dept',
streams_name => 'db1_to_db3',
source_queue_name => 'strmadmin.streams_queue',
destination_queue_name => ,
include_dml => true,
include_ddl => true,
source_database => 'db1');
END;
/
檢查傳播程式作業
SELECT job,TO_CHAR(last_date, 'DD-Mon-YYYY HH24:MI:SS') last_date,TO_CHAR(next_date, 'DD-Mon-YYYY HH24:MI:SS') next_date,what FROM dba_jobs;
6.配置捕捉程式(db1)
CONNECT
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;
/
7.配置初始 SCN
在應用程式工作前必須在目的表中配置源表的 SCN。如果目的表已經存在，可用 exp/imp 後設資料完成。
exp FILE=dept_instant.dmp TABLES=dept OBJECT_CONSISTENT=y ROWS=n
imp FILE=dept_instant.dmp IGNORE=y COMMIT=y LOG=import.log STREAMS_INSTANTIATION=y
imp FILE=dept_instant.dmp IGNORE=y COMMIT=y LOG=import.log STREAMS_INSTANTIATION=y
因為在遷移後設資料時 SUPPLEMENTAL 日誌也被遷移。因為捕捉程式還沒有啟動，所以可以刪除這些日誌：
CONN AS SYSDBA
ALTER TABLE scott.dept DROP SUPPLEMENTAL LOG GROUP log_group_dept_pk;
CONN AS SYSDBA
ALTER TABLE scott.dept DROP SUPPLEMENTAL LOG GROUP log_group_dept_pk;
用 DBMS_APPLY_ADM 包設定 SCN
DECLARE
v_scn NUMBER;
BEGIN
v_scn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
(
source_object_name => 'scott.dept',
source_database_name => 'db1',
instantiation_scn => v_scn);
END;
/
DECLARE
v_scn NUMBER;
BEGIN
v_scn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
(
source_object_name => 'scott.dept',
source_database_name => 'db1',
instantiation_scn => v_scn);
END;
/
8.配置應用程式(db2,db3)
db2:
CONNECT
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 => 'db1');
END;
/
db3:
CONNECT
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 => 'db1');
END;
9.啟動應用程式(db2,db3)
CONNECT
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;
/
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;
/
10.啟動捕捉程式(db1)
CONNECT
BEGIN
DBMS_CAPTURE_ADM.START_CAPTURE(
capture_name => 'capture_simp');
END;
/

四.dbms_streams_adm的maintain_global過程如何配置stream全庫複製方法，適用於10gR2及以後版本
主從庫SID和目錄結構要求一致
1 在stream進行配置前，需要做些準備工作
源庫與目標庫初始化引數的設定
alter system set aq_tm_processes=4 scope=spfile;
alter system set job_queue_processes=5 scope=spfile;
alter system set global_names=true scope=spfile;
alter system set streams_pool_size=51m scope=spfile;
說明streams_pool_size在生產環境中最好>200m
b 源庫與目標庫tnsnames.ora配置
確保正確，可用tnsping通
c 源庫與目標庫複製管理員的建立
create user strmadmin identified by strmadmin default tablespace &tbs_name quota unlimited on &tbs_name;
grant connect, resource, dba to strmadmin;
d 源庫與目標庫建立互連的資料鏈
connect ;
create public database link db2.com connect to strmadmin identified by strmadmin using 'db2';
connect ;
create public database link db1.com connect to strmadmin identified by strmadmin using 'db1';
(說明:必須確保雙方的資料庫鏈是可以連通,用pre_instantiation_setup/post_instantiation_setup過程時db link必須用db_name.domain的格式)
e 源庫與目標庫必須處於歸檔模式
f 源庫與目標庫必須建立directory
create directory dir_db1 as '/u01/bak';
create directory dir_db2 as '/u01/bak';
2 在源庫執行MAINTAIN_GLOBAL過程(整庫級)
connect ;
begin
dbms_streams_adm.maintain_global(
source_directory_object => 'dir_db1',
destination_directory_object => 'dir_db2',
source_database => 'db1.com',
destination_database => 'db2.com',
perform_actions => true,
include_ddl => true,
instantiation => DBMS_STREAMS_ADM.INSTANTIATION_FULL_NETWORK);
end;
說明:在執行maintain_global時,源庫與目標庫必須建立directory,然後在源庫執行, 目標庫幾乎什麼都不用做,stream環境已經配置好
其中，instantiation指定初始化的方式
DBMS_STREAMS_ADM.INSTANTIATION_FULL：expdp全庫匯出然後impdp全庫匯入
DBMS_STREAMS_ADM.INSTANTIATION_FULL_NETWORK：使用data pump直接透過網路匯入的特性初始化
DBMS_STREAMS_ADM.INSTANTIATION_NONE：不執行初始化。這個選現只有在perform_actions=false的情況下有效，也就是指定先生成指令碼，手工初始化，然後在執行配置指令碼。
begin
DBMS_STREAMS_ADM.MAINTAIN_GLOBAL(
source_directory_object => 'dir_db1',
destination_directory_object => 'dir_db2',
source_database => 'db1.com',
destination_database => 'db2.com',
perform_actions => false,
script_directory_object =>'DIR_db1',
script_name => 'global_script.sql',
dump_file_name => 'streams_rep.dmp',
bi_directional => false,
include_ddl => true,
instantiation => DBMS_STREAMS_ADM.INSTANTIATION_NONE);
end;

在源庫執行MAINTAIN_schemas過程(schema級，注意:從庫schemas最好不存在)
connect ;
begin
dbms_streams_adm.maintain_schemas(
schema_names => 'hs_his,hs_users',
source_directory_object => null,
destination_directory_object => null,
source_database => 'db1.com',
destination_database => 'db2.com',
perform_actions => true,
bi_directional => false,
include_ddl => true,
instantiation => dbms_streams_adm.instantiation_schema_network);
end;
在源庫執行MAINTAIN_TTS過程(table級)
connect ;
declare
v_tables dbms_utility.uncl_array;
begin
v_tables(1) := 'scott.scott';
v_tables(2) := 'scott.tiger';
dbms_streams_adm.maintain_tables(
table_names => v_tables,
source_directory_object => null,
destination_directory_object => null,
source_database => 'db1.com',
destination_database => 'db2.com',
perform_actions => true,
bi_directional => false,
include_ddl => true,
instantiation => dbms_streams_adm.instantiation_table_network);
end;
在源庫執行MAINTAIN_TTS過程(表空間級)
檢查表空間的自包含
exec sys.dbms_tts.transport_set_check('TEST01',true,true);
select * from sys.transport_set_violations;
connect ;
declare
v_ts dbms_streams_tablespace_adm.tablespace_set;
begin
v_ts(1) := 'TEST01';
dbms_streams_adm.maintain_tts(
tablespace_names => v_ts,
source_directory_object => 'dir_db1',
destination_directory_object => 'dir_db2',
source_database => 'db1.com',
destination_database => 'db2.com',
perform_actions => true,
/*bi_directional => true,*/
include_ddl => true);
end;
3 如果在執行2的過程時失敗,需要清除指令碼
--select script_id from dba_recoverable_script;
--exec dbms_streams_adm.RECOVER_OPERATION('&1','PURGE');
declare
v_script_id varchar2(32);
begin
select script_id into v_script_id from dba_recoverable_script;
dbms_streams_adm.RECOVER_OPERATION(v_script_id,'PURGE');
exception
when no_data_found then
DBMS_OUTPUT.PUT_LINe('no data found') ;
when others then

3 如果在執行2的過程時失敗,需要清除指令碼
--select script_id from dba_recoverable_script;
--exec dbms_streams_adm.RECOVER_OPERATION('&1','PURGE');
declare
v_script_id varchar2(32);
begin
select script_id into v_script_id from dba_recoverable_script;
dbms_streams_adm.RECOVER_OPERATION(v_script_id,'PURGE');
exception
when no_data_found then
DBMS_OUTPUT.PUT_LINe('no data found') ;
when others then
DBMS_OUTPUT.PUT_LINe('error~!') ;
end;
4 說明,如果已經存在複製環境,再配置其它型別的複製將會導致失敗,所以配置複製前
需要清除已經存在的複製環境.
源與目標庫都做:
--exec dbms_streams_adm.REMOVE_STREAMS_CONFIGURATION;
begin
for cur_pro in (select propagation_name from dba_propagation) loop
dbms_propagation_adm.drop_propagation(cur_pro.propagation_name);
end loop;
dbms_streams_adm.REMOVE_STREAMS_CONFIGURATION;
end;
5 配置失敗,發現目標庫apply orror
select * from dba_apply;
select * from dba_apply_error;
6 完成stream的表空間複製
connect ;
dbms_capture_adm.prepare_schema_instantiation(schema_name => 'hs_his');
declare
v_scn number;
begin
v_scn := dbms_flashback.get_system_change_number();
(
source_schema_name => 'hs_his',
source_database_name => 'db1.com',
instantiation_scn => v_scn);
end;
