Goldengate双向复制配置

一、Goldengate双向复制配置

站在用户的角度思考问题,与客户深入沟通,找到尼河口网站设计与尼河口网站推广的解决方案,凭借多年的经验,让设计与互联网技术结合,创造个性化、用户体验好的作品,建站类型包括:成都网站设计、成都网站制作、外贸网站建设、企业官网、英文网站、手机端网站、网站推广、域名与空间、网站空间、企业邮箱。业务覆盖尼河口地区。

 

1.1.在进行如下配置之前,先在源数据库source system(原来的目标数据库)端

添加辅助的redolog配置:

SQL>alter database add supplemental log data;

SQL>alter system switch logfile;

SQL>alter database force logging;

 

 

 

1.2.在原Source和原Target分别用scott用户创建一张emp_ogg表

 SQL> create table emp_ogg as select * from emp where 1=0;//原source库建立表但不插入数据

 

Table created.

单项复制时Source端是EINI_1进程,Target端是RINI_1进程,双向复制时反之,以便完成两表的初始化同步,配置如下:

原Source

GGSCI (gc2) 36> ADD REPLICAT RINI_1, SPECIALRUN

REPLICAT added.

 

GGSCI (gc2) 43> EDIT PARAMS RINI_1

 

-- GoldenGate Initial Load Delivery

--

REPLICAT RINI_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

ASSUMETARGETDEFS

USERID ogg, PASSWORD ogg

DISCARDFILE ./dirrpt/RINIaa.dsc, PURGE

MAP scott.*, TARGET scott.*;

 

原Target

GGSCI (oraclelinux54.cuug.net) 10> ADD EXTRACT EINI_1, SOURCEISTABLE

EXTRACT added.

 

GGSCI (oraclelinux54.cuug.net) 11>  INFO EXTRACT *, TASKS

RMTHOSTgc2, MGRPORT 7809

RMTTASK REPLICAT, GROUP RINI_1

Output to RINI_1:

 

From Table SCOTT.EMP_OGG:

       #                  inserts:        14                                  //可以看出两边已经同步成功

       #                   updates:         0

       #                   deletes:         0

       #                  discards:         0

 

1.3.在ogg环境下,添加日志跟踪:

GGSCI (oraclelinux54.cuug.net)DBLOGIN USERID ogg, PASSWORD ogg

GGSCI (oraclelinux54.cuug.net)ADD TRANDATA scott.*        //这里为了试验方便,我们设置为scott下全部表均设为可同步状态

2013-08-13 03:21:18  GGS WARNING     109  No unique key is defined for table EMP_OGG. All viable columns will be used to represent the key, but may not guarantee uniqueness.  KEYCOLS may be used to define the key.

2013-08-13 03:21:18  GGS WARNING    301  Failed to add supplemental log group on table SCOTT.EMP_OGG due to ORA-01031: insufficient privileges, SQL ALTER TABLE "SCOTT"."EMP_OGG" ADD SUPPLEMENTAL LOG GROUP "GGS_EMP_OGG_74686" ("EMPNO","ENAME","JOB","MGR","HIREDATE","SAL","COMM","DEPTNO") ALWAYS  /* GOLDENGATE_DDL_REPLICATION */.

 

解决办法:

SQL>alter table emp_ogg add constraint emp_ogg_pk primary key(empno);

SQL> grant alter any table to ogg;

Grant succeeded.

 

1.4.配置extract

GGSCI (gc2) 71>EDIT PARAMS EORA_1    //编辑前先停止进程

 

EXTRACT EORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

USERID ogg, PASSWORD ogg

EXTTRAIL ./dirdat/aa

TABLE scott.*;

DDL INCLUDE OBJNAME "scott.*"

TRANLOGOPTIONS EXCLUDEUSER ogg          //双向复制关键

GGSCI (oraclelinux54.cuug.net) 74>EDIT PARAMS EORA_1  //编辑前先停止进程

EXTRACT EORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

USERID ogg, PASSWORD ogg

TRANLOGOPTIONS EXCLUDEUSER ogg

EXTTRAIL ./dirdat/aa

TABLE scott.*;

DDL INCLUDE OBJNAME "scott.*"

GGSCI (双节点执行)> ADD EXTRACT EORA_1, TRANLOG, BEGIN NOW

注:

ADD EXTRACT EORA_1:添加EXTRACT进程,这就是一直运行,一段停止redo里的日志就没人去抓取了

TRANLOG, BEGIN NOW:现在开始同步日志,也可以用异步,那就要另外配置

EXTRACT added.

GGSCI (双节点执行)>  ADD EXTTRAIL ./dirdat/aa, EXTRACT EORA_1, MEGABYTES 5             //添加跟踪文件给EORA_1用,大小为5M

EXTTRAIL added.

GGSCI (双节点执行)>START EXTRACT EORA_1

 

1.5.配置pump进程

GGSCI (gc2) 72> EDIT PARAMS PORA_1  //编辑前先停止进程

EXTRACT PORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

PASSTHRU

RMTHOSToraclelinux54.cuug.net, MGRPORT 7809

RMTTRAIL /u01/app/ogg/dirdat/pa

TABLE scott.*;

 

GGSCI (oraclelinux54.cuug.net) 75> EDIT PARAMS PORA_1 //编辑前先停止进程

EXTRACT PORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

PASSTHRU

RMTHOSTgc2, MGRPORT 7809

RMTTRAIL ./dirdat/pa

TABLE scott.*;

 

GGSCI (双节点执行)> ADD EXTRACT PORA_1, EXTTRAILSOURCE ./dirdat/aa          // 告诉PORA_1要传送哪个路径下的跟踪信息

EXTRACT added.

GGSCI (双节点执行)>  ADD RMTTRAIL ./dirdat/pa, EXTRACT PORA_1, MEGABYTES 5      //表示把捕获到的信息传送到远程的哪个目录的文件中

RMTTRAIL added.

GGSCI (双节点执行)> START EXTRACT PORA_1

 

配置replicate

GGSCI (gc2) 74> EDIT PARAM RORA_1

REPLICAT RORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

USERID ogg, PASSWORD ogg

HANDLECOLLISIONS

ASSUMETARGETDEFS

DISCARDFILE ./dirrpt/RORA_aa.DSC, PURGE

DDL INCLUDE ALL

DDLERROR DEFAULT IGNORE RETRYOP MAXRETRIES 3 RETRYDELAY 5

DDLERROR DEFAULT DISCARD

DDLERROR DEFAULT IGNORE RETRYOP

MAP scott.*, TARGET scott.*;

 

GGSCI (oraclelinux54.cuug.net) 87> EDIT PARAM RORA_1

REPLICAT RORA_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

DDL INCLUDE ALL

DDLERROR DEFAULT IGNORE RETRYOP MAXRETRIES 3 RETRYDELAY 5

DDLERROR DEFAULT DISCARD

DDLERROR DEFAULT IGNORE RETRYOP

MAP scott.*, TARGET scott.*;

 

 

GGSCI (双节点执行) 87>ADD REPLICAT RORA_1, EXTTRAIL ./dirdat/pa       //表示从哪里提取传送过来的信息

GGSCI (双节点执行) 87>START REPLICAT RORA_1

 

SQL> conn / as sysdba

Connected.

SQL> grant insert on scott.emp_ogg to ogg;

 

Grant succeeded.

 

SQL> conn / as sysdba

Connected.

SQL> grant delete on scott.emp_ogg to ogg;

 

Grant succeeded.

 

SQL>grant update on scott.emp_ogg to ogg;

 

Grant succeeded.

 

 

 

 

二、配置checkpoint

GGSCI (oraclelinux54.cuug.net)  EDIT PARAMS ./GLOBALS

CHECKPOINTTABLE ogg.ggschkpt

GGSCI (oraclelinux54.cuug.net)  exit

GGSCI (oraclelinux54.cuug.net)  DBLOGIN USERID ogg, PASSWORD ogg

Successfully logged into database.

GGSCI (oraclelinux54.cuug.net)  ADD CHECKPOINTTABLE    //如果单项复制已经做了,这里不用再添加

 

 

应该看到,两节点的进程都为Running状态

GGSCI (gc2) 73> info all

 

Program     Status      Group       Lag           Time Since Chkpt

 

MANAGER     RUNNING                                          

EXTRACT     RUNNING     EORA_1      00:00:00      00:00:02   

EXTRACT     RUNNING     PORA_1      00:00:00      00:00:04   

REPLICAT    RUNNING     RORA_1      00:00:00      00:00:01 

GGSCI (oraclelinux54.cuug.net) 88> info all

 

Program     Status      Group       Lag           Time Since Chkpt

 

MANAGER     RUNNING                                          

EXTRACT     RUNNING     EORA_1      00:00:00      00:00:09   

EXTRACT     RUNNING     PORA_1      00:00:00      00:00:02   

REPLICAT    RUNNING     RORA_1      00:00:00      00:00:05 

 

三、测试双向传送结果

3.1.source到target

Sourcesystem

SQL> INSERT INTO emp_ogg VALUES(8000,'HL','CLERK',7902,'12-DEC-80',800,100,20);

 

1 row created.

 

SQL> commit;

 

Commit complete.

 

SQL> select * from emp_ogg;

 

     EMPNO ENAME      JOB              MGR HIREDATE         SAL       COMM     DEPTNO

---------- ---------- --------- ---------- --------- ---------- ---------- ----------

        8000 HL         CLERK           7902 12-DEC-80        800        100         20 

Target system

SQL> select * from emp_ogg;

    EMPNO ENAME      JOB               MGR HIREDATE                     SAL       COMM     DEPTNO

---------- ---------- ---------- ---------- --------------------- ---------- ---------- ----------

    8000 HL         CLERK            7902 1980-12-12 : 00:00:00        800        100         20 

3.2target 到 source

Target system

SQL> select * from tcustmer;

 

CUST NAME                           CITY                 ST

---- ------------------------------ -------------------- --

WILL BG SOFTWARE CO.                SEATTLE              WA

JANE ROCKY FLYER INC.               DENVER               CO

 

SQL> insert into tcustmer values ('HL','zai','cuug','en');

1 row created.

SQL> commit;

Commit complete.

Source  system

SQL> select * from tcustmer;

 

CUST NAME                           CITY                 ST

---- ------------------------------ -------------------- --

WILL BG SOFTWARE CO.                SEATTLE              WA

JANE ROCKY FLYER INC.               DENVER               CO

helei  zai                            cuug                 en

 

四、支持DDL复制配置

 

4.1在两个节点执行执行DDL同步脚本命令:

 

先进入goldengate软件安装目录,以SYSDBA身份登录oracle执行以下脚本,执行脚本过程中,需要输入的用户全部是ogg,安装模式为INITIALSETUP,如果数据字典或者某些内部的包有错误,则需要运行catalog.sql和catproc.sql脚本。

SQL>show parameter recyclebin;

 

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

recyclebin                           string     off                                                                 必须是off

 

 这里执行第二个脚本@ddl_setup时会报一个recyclebin的错误,而且只能在Pfile中修改recyclebin=off后用pfile起库,执行两个清除脚本,再重新运行一下脚本

SQL>@marker_setup

SQL>@ddl_setup

SQL>@role_setup

SQL>grant GGS_GGSUSER_ROLE to ogg;

SQL>@ddl_enable

 

如果某项脚本执行错误,需要重新执行时,先要执行清除的脚本:ddl_remove.sql和marker_remove.sql
