物化视图常用维护操作

1，查看刷新组信息：

SQL> select rowner,rname,refgroup,job,next_date,interval,broken from dba_refresh;

ROWNER     RNAME           REFGROUP        JOB NEXT_DATE           INTERVAL             B
---------- ------------- ---------- ---------- ------------------- -------------------- -
MVADMIN    REP_REFRESH            1         41 2012-09-03 10:36:21 sysdate+1/(24*12)    N

2，查看刷新组内包含哪些要刷新的物化视图

SQL> select owner,name,rowner,rname,refgroup,job,next_date from dba_refresh_children;

OWNER    NAME     ROWNER     RNAME           REFGROUP        JOB NEXT_DATE
-------- -------- ---------- ------------- ---------- ---------- -------------------
TESTER   T1MV     MVADMIN    REP_REFRESH            1         41 2012-09-03 10:36:21
TESTER   T2MV     MVADMIN    REP_REFRESH            1         41 2012-09-03 10:36:21

3，查看都有哪些物化视图

SQL> select owner,mview_name,MASTER_LINK,REFRESH_METHOD,LAST_REFRESH_DATE from all_mviews;

OWNER    MVIEW_NAME      MASTER_LIN REFRESH_ LAST_REFRESH_DATE
-------- --------------- ---------- -------- -------------------
TESTER   T1MV            @NEWDB.MDU FAST     2012-09-03 10:36:01
TESTER   T2MV            @NEWDB.MDU FORCE    2012-09-03 10:36:01

4，查看job的信息

SQL> select job,log_user,last_date,next_date,broken,interval,failures,what from dba_jobs where job=41;

       JOB LOG_USER   LAST_DATE           NEXT_DATE           B INTERVAL               FAILURES WHAT
---------- ---------- ------------------- ------------------- - -------------------- ---------- ------------------------------
      41 MVADMIN    2012-09-03 11:09:09 2012-09-03 11:14:09 N sysdate+1/(24*12)             0 dbms_refresh.refresh('"MVADMIN
                                                                                                "."REP_REFRESH"');

5，与刷新组相关的操作:

--新建一个刷新组
begin
DBMS_REFRESH.MAKE (
    name => 'mvadmin.rep_refresh',
    list => '',
    next_date => SYSDATE,
    interval => 'SYSDATE + 1/24',
    implicit_destroy => FALSE,
    rollback_seg => '',
    push_deferred_rpc => TRUE,
    refresh_after_errors => FALSE);
end;
/

--添加MV到一个刷新组
begin
DBMS_REFRESH.ADD(
    name => 'rep_refresh',
    list => 'tester.t1mv’
    );
end;
/

--更改刷新组的刷新间隔
begin
DBMS_REFRESH.CHANGE(
    name => 'rep_refresh',
    next_date => sysdate,
    interval => sysdate+(1/(24*60))
    );
end;
/
                                                                   
--手动刷新一个刷新组
SQL> exec DBMS_REFRESH.REFRESH('rep_refresh'); 

---手动运行一个job

SQL> exec dbms_job.run(41);                                                                  
                                                                   
--从刷新组中移除一个物化视图
begin
DBMS_REFRESH.SUBTRACT (
   name => 'mvadmin.rep_refresh',
   list => 'tester.t1mv’
   );
end;
/                                                                   

--移除所有的物化视图并删除刷新组
exec DBMS_REFRESH.DESTROY('rep_refresh');   

6，物化视图对象的相关操作

创建物化视图日志表(一般在主站点操作)：

CREATE MATERIALIZED VIEW LOG ON schema.object;

创建物化视图(一般在复制端进行)：

CREATE MATERIALIZED VIEW schema.object
REFRESH FAST WITH PRIMARY KEY AS SELECT * FROM schema.object@dblink;

将物化视图添加到刷新组：

BEGIN
DBMS_REFRESH.ADD (
name => 'mvadmin.rep_refresh',-----刷新组名
list => ‘schema.object’, ----物化视图名
lax => TRUE);
END;
/
