  • Goldengate实现在线数据迁移

    Goldengate的一大卖点就是可以实现在线的数据迁移,这意味着在整个过程中我们无需关闭数据库,甚至于无需停止应用。在<How to create a GoldenGate uni-directional target database in a production database zero downtime>中,大致介绍了实现零下线时间数据迁移所涉及的步骤,包括:
    1. 在source与target主机上完成OGG的初始化配置
    2. 创建extract及exttrail
    3. 创建pump
    4. 启动本地extract和pump
    5. 创建带有HANDLECOLLISIONS参数的replicat,但不启动它
    6. 完成数据的initial load即数据初始化
    7. 启动replicat
    8. 当replicat追上extract后取消replicat的HANDLECOLLISIONS参数
    接下来我们通过以下实例来实践OGG的在线数据迁移:
    SQL> conn clinic/clinic
    Connected.
    
    /* 以clinic为应用用户 */
    
    SQL> create table tv (t1 int primary key,t2 int,t3 varchar2(30));
    Table created.
    
    /* 为别在source和target创建该测试用表,在这里我们先不考虑同步DDL*/
    
    SQL> create sequence seqt1 start with 1 increment by 1;
    Sequence created.
    
    declare
      rnd number(9,2);
    begin
       for i in 1..100000 loop
         insert into tv values(seqt1.nextval,i*dbms_random.value,'MACLEAN IS TESTING');
         commit;
       end loop;
    end;
    PL/SQL procedure successfully completed.
    
    /* 在源端随机生成10w行数据 */
    
    begin
       loop
        delete from tv where rownum=1;
         commit;
         insert into tv values(seqt1.nextval,200000*dbms_random.value,'MACLEAN IS UPDATING');
         commit;
    	 insert into tv values(seqt1.nextval,300000*dbms_random.value,'MACLEAN IS UPDATING');
    	 commit;
    	update tv set t2=t2+10 where rownum=1;
    	commit;
         dbms_lock.sleep(1);
         end loop;
    end;
    
    /* 以上匿名块可以造成简易的数据变化,它会在每1秒钟删除/更新/插入TV表的部分数据
        我们打开多个窗口执行以上匿名块,以模拟在线业务
    */
    
    以上为测试前提工作,接下来我们正式配置OGG FOR ZERO DOWNTIME MIGRATION:
    GGSCI (rh2.oracle.com) 3> dblogin userid maclean
    Password:
    Successfully logged into database.
    
    GGSCI (rh2.oracle.com) 5> add trandata clinic.tv
    Logging of supplemental redo data enabled for table CLINIC.TV.
    
    /* 通过add trandata命令为tv表加上追加日志 */
    
    GGSCI (rh2.oracle.com) 6> add extract load2,tranlog,begin now
    EXTRACT added.
    
    GGSCI (rh2.oracle.com) 7> add rmttrail /s01/new/ze,megabytes 200,extract load2
    RMTTRAIL added.
    
    GGSCI (rh2.oracle.com) 10> view params load2
    
    extract load2
    userid maclean, password AACAAAAAAAAAAAHANCUEFHPAVCYDNJVD,encryptkey default
    RMTHOST rh3.oracle.com, MGRPORT 7809
    RMTTRAIL /s01/new/ze
    Table clinic.tv;
    
    /* 为了让整个过程更简洁,我们在这里不适用pump */
    
    GGSCI (rh2.oracle.com) 9> start load2
    Sending START request to MANAGER ...
    EXTRACT LOAD2 starting

    接下来停止模拟的在线业务,进行数据对比。首先使用Goldengate veridata创建group及compare pair等配置: 接着生成job,并执行: Job运行的结果界面: 对比发现同步正常的报告:

    begin
       loop
        delete from tv where rownum=1;
         commit;
         insert into tv values(seqt1.nextval,200000*dbms_random.value,'MACLEAN IS UPDATING');
         commit;
    	 insert into tv values(seqt1.nextval,300000*dbms_random.value,'MACLEAN IS UPDATING');
    	 commit;
    	update tv set t2=t2+10 where rownum=1;
    	commit;
         dbms_lock.sleep(1);
         end loop;
    end;
    /
    
    /* 在源端打开模拟的应用程序 */
    
    /* 在target插入一条额外的纪录 */
    
    SQL> insert into tv values(99993242,1213,'OUT OF SYNC');

    再次运行Goldengate veridata中相关的job,可以在job相关的日志中看到详细的out-of-sync纪录信息:
