测试环境:
OS: Windows Xp
DB: Oracle 10.2.0.3 32bit
一、安装goldengate
goldengate安装不是很复杂,在oracle官方网站上下载ggs_Windows_x86_ora10g_32bit.zip,放到一个目录(我的目录是E:\ggate)解压即可。
E:\ggate>ggsci
Oracle GoldenGate Command Interpreter for Oracle
Version 11.1.1.1.2 OGGCORE_11.1.1.1.2_PLATFORMS_111004.2100
Windows (optimized), Oracle 10g on Oct 5 201100:50:35
Copyright (C) 1995, 2011, Oracle and/or its affiliates. Allrights reserved.

GGSCI (mybole) 2> createsudbirs --创建需要的目录
二、配置Source DB
GoldenGate通过抓取源端数据库重做日志进行分析,将获取的数据应用到目标端,实现数据同步。因此,源数据库需要必须处于归档模式,并启用附加日志和强制日志。
归档模式、附加日志、强制日志
SQL> select log_mode,supplemental_log_data_min,force_loggingfrom v$database;
LOG_MODE SUPPLEME FOR
------------ -------- ---
ARCHIVELOG YES YES
如果为NO,需要添加,命令如下
1)archivelog
SQL>shutdown immediate
SQL>startup mount
SQL>alter database archivelog;
SQL>alter database open;
(2) force logging
SQL>alterdatabase force logging;
(3)supplemental log data
SQL>alterdatabase add supplemental log data
如果启用DDL 支持,必须关闭recycle bin。官网的解释如下:
If the recyclebin is enabled, the Oracle GoldenGate DDL triggersession receives implicitrecycle bin DDL operations that cause thetrigger to fail.
Oracle 11g:
SQL> alter system set recyclebin=offscope=spfile;
System altered.
如果数据库是10g,需要关闭recyclebin并重启;或者手工purge recyclebin。
三、创建user
1. 创建存放DDL信息的user并赋权
SQL> create user ggate identified by ggate default tablespaceusers temporary tablespace temp;
User created.
SQL> grant connect,resource to ggate;
Grant succeeded.
SQL> grant execute on utl_file to ggate;
Grant succeeded.
2.在Source Db上创建测试用户
SQL>create user ggs identified by ggs default tablespaceusers temporary tablespace temp;
SQL>grant dba to ggs;
3.在Target DB上创建测试用户
SQL>create user ggt identified by ggt default tablespaceusers temporary tablespace temp;
SQL>grant dba to ggt;
3.退出所有使用Oracle的session,然后使用SYSDBA权限的用户执行如下脚本:
E:\>cdE:\ggate
E:\ggate>sqlplus / as sysdba
SQL>@marker_setup.sql; --提示过程中输入用户:ggate
SQL>@ddl_setup.sql; --提示过程中输入用户:ggate;INITIALSETUP
SQL>@role_setup.sql; --提示过程中输入用户:ggate
SQL>grantGGS_GGSUSER_ROLE to ggate;
SQL>@ddl_enable.sql;
四、配置相关进程
1.在Source 和Target 上配置Manager
GGSCI (gg1) 1> info all
Program Status Group Lag Time Since Chkpt
MANAGER STOPPED
GGSCI (gg1) 2> edit params mgr
输入如下内容:
PORT 7809
GGSCI (gg1) 3> start manager
Manager started.
2.配置SourceDB 的复制队列
先连接到数据库,测试连接:
GGSCI (gg1) 10> dblogin userid ggate, password ggate
Successfully logged into database.
增加一个抽取:
GGSCI (gg1) 11> add extractext1,tranlog, begin now
2011-11-08 20:36:47 INFO OGG-01749 Successfully registeredEXTRACT EXT1 to start managing log retentionat SCN 1121060.
EXTRACT added.
GGSCI (gg1) 12> add exttrailE:\ggate\dirdat\lt, extract ext1
EXTTRAIL added
编辑抽取进程ext1参数:
GGSCI (gg1) 13> edit params ext1
extract ext1
userid ggate,password ggate
rmthost 127.0.0.1,mgrport 7809
rmttrail E:\ggate\dirdat\lt
dynamicresolution
table ggs.*;
GGSCI (gg1) 14> start ext1
GGSCI (gg1) 14> info all
3.配置TargetDB 同步队列
3.1在Target 端添加checkpoint表:
GGSCI (gg2) 6> edit params./GLOBAL
GGSCHEMA ggate
CHECKPOINTTABLEggate.checkpoint
添加如上2条记录。
GGSCI (gg2) 12> dblogin useridggate,password ggate
Successfully logged intodatabase.
--说明,这个用户是在Source 库启用DDL 创建的,我在Target库也创建了这个用户。
GGSCI (gg2) 13> add checkpointtableggate.checkpoint
Successfully created checkpointtableGGATE.CHECKPOINT.
3.2创建同步队列
GGSCI (gg2) 14> add replicatrep1,exttrail E:\ggate\dirdat\lt, checkpointtableggate.checkpoint
REPLICAT added.
GGSCI (gg2) 15> edit params rep1
replicat rep1
userid ggate,password ggate
assumetargetdefs
discardfile E:\ggate\dirdat\rep1_discard.txt,append
MAP ggs.*, TARGET ggt.*;
3.3开启同步队列
GGSCI (gg2) 14> start ext1
GGSCI (gg2) 14> start rep1
GGSCI (gg2) 14> info all
Program Status Group Lag Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EXT1 00:00:00 00:00:07
REPLICAT RUNNING REP1 00:00:00 00:00:06
所有的进程状态都是RUNNING,正常。
五、测试Data 复制
1.在Source DB端和Target DB上都建立测试表
SQL> conn ggs/ggs
Connected.
SQL> host pwd
E:\ggate
SQL> @demo_ora_create.sql
Table Created.
SQL> conn ggt/ggt
Connected.
SQL> host pwd
E:\ggate
SQL> @demo_ora_create.sql
Table Created.
2.在Source DB端插入数据
SQL>@demo_ora_insert.sql
1 row created.
1 row created.
1 row created.
1 row created.
Commit complete.
3.在Target DB端查看
SQL> select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ ------- ----------
TCUSTMER TABLE
TCUSTORD TABLE
SQL> select * from TCUSTMER;
CUSTNAME CITY ST
---- ------------------------------ -------------------- --
WILL BG SOFTWARECO. SEATTLE WA
JANE ROCKY FLYERINC. DENVER CO
SQL> select * from TCUSTORD;
CUSTORDER_DATE PRODUCT_ ORDER_ID PRODUCT_PRICEPRODUCT_AMOUNT
---- ------------------- -------- ---------- ---------------------------
TRANSACTION_ID
--------------
WILL 1994-09-30 15:33:00CAR 144 17520 3
100
JANE 1995-11-11 13:52:00PLANE 256 133300 1
100
数据同步过来了。
一些错误的处理:
ERROR OGG-00868 Oracle GoldenGate Delivery for Oracle,REP1.prm: OCI error (1008-ORA-01008: not allvariables bound) executing query to fetch primary key, SQL
解决:sqlplus / as sysdba
SQL>alter system flushshared_pool;
应该还有其他的办法可以解决这个问题,暂时没搞清楚。
