2.创建保存冲突数据的数据表

a.missing_rows表用以保存冲突行
SQL> create table hawa.missing_rows_test
2 as
3 select * from hawa.test where 1=0;

Table created

b.用于保存缺失行位置及rowid
SQL> create table hawa.MISSING_LOCATION_TEST (
2 present VARCHAR2(128),
3 absent VARCHAR2(128),
4 r_id ROWID);

Table created

3.使用dbms_rectifier_diff.DIFFERENCES查找缺失记录

SQL> begin dbms_rectifier_diff.DIFFERENCES( 2 SNAME1 =>'HAWA', 3 ONAME1 =>'TEST', 4 REFERENCE_SITE =>'AVATAR.COOLYOUNG.COM.CN', 5 SNAME2 =>'HAWA', 6 ONAME2 =>'TEST', 7 COMPARISON_SITE =>'AUTHAA.COOLYOUNG.COM.CN', 8 WHERE_CLAUSE =>NULL, 9 COLUMN_LIST =>NULL, 10 MISSING_ROWS_SNAME =>'HAWA', 11 MISSING_ROWS_ONAME1 =>'MISSING_ROWS_TEST', 12 MISSING_ROWS_ONAME2 =>'MISSING_LOCATION_TEST', 13 MISSING_ROWS_SITE =>'AVATAR.COOLYOUNG.COM.CN', 14 MAX_MISSING =>500, 15 COMMIT_ROWS =>100 16 ); 17 end; 18 / PL/SQL procedure successfully completed

冲突记录被保存在我们创建的指定表中
SQL> select count(*) from hawa.missing_rows_test;

COUNT(*)
----------
172

共有172条差异记录

SQL> select count(*) from hawa.test;

COUNT(*)
----------
548

SQL> select count(*) from hawa.test@authaa;

COUNT(*)
----------
376

SQL> select count(*) from hawa.missing_location_test;

COUNT(*)
----------
172

4.使用DBMS_RECTIFIER_DIFF.RECTIFY进行数据整合

首先需要注意的是:
RECTIFY过程使用DIFFERENCES产生的数据进行数据调整。
在第一个表中存在，在第二个表中不存在的数据将被插入第二张表。
在第二个表中存在，在第一个个表中不存在的数据将被从第二张表中删除。

另外，在这个数据纠正过程中，你可以使用dbms_repcat.suspend_master_activity将复制组暂时挂起。
这样便于保证数据完整性。
但这不是必须的，如果复制一直激活，可能会有新的冲突出现。

SQL> BEGIN DBMS_RECTIFIER_DIFF.RECTIFY(
  2  SNAME1                         =>'HAWA',
  3  ONAME1                         =>'TEST',
  4  REFERENCE_SITE                 =>'AVATAR.COOLYOUNG.COM.CN',
  5  SNAME2                         =>'HAWA',
  6  ONAME2                         =>'TEST',
  7  COMPARISON_SITE                =>'AUTHAA.COOLYOUNG.COM.CN',
  8  COLUMN_LIST                    =>NULL,
  9  MISSING_ROWS_SNAME             =>'HAWA',
 10  MISSING_ROWS_ONAME1            =>'MISSING_ROWS_TEST',
 11  MISSING_ROWS_ONAME2            =>'MISSING_LOCATION_TEST',
 12  MISSING_ROWS_SITE              =>'AVATAR.COOLYOUNG.COM.CN',
 13  COMMIT_ROWS                    =>100
 14  );
 15  END;
 16  /
PL/SQL procedure successfully completed
SQL> select count(*) from hawa.test@authaa;
  COUNT(*)
----------
       548
SQL> select count(*) from hawa.test;
  COUNT(*)

数据矫正完成以后，数据会自动从missing_rows表中删除。

SQL> select count(*) from hawa.missing_rows_test;

COUNT(*)
----------
0
