一、安装goldengate软件
1.1测试环境
[oracle@redhat6 ~]$ uname -a
Linux redhat6 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
SQL> select * from v$version where rownum=1;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
1.2.安装OGG
[oracle@redhat6 ~]$ cd /u01/ogg
[oracle@redhat6 ogg]$unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[oracle@redhat6 ogg]$ tar -xvf fbo_ggs_Linux_x64_ora11g_64bit.tar
1.3.添加环境变量
[oracle@redhat6 ogg]$ vi /home/oracle/.bash_profile
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export LD_LIBRARY_PATH
export PATH=/u01/ogg:$PATH
export GGATE=/u01/ogg
1.4.使用ggsci工具创建目录
[oracle@redhat6 ogg]$ ./ggsci
Oracle GoldenGate Command Interpreter for Oracle
Version 11.2.1.0.1 OGGCORE_11.2.1.0.1_PLATFORMS_120423.0230_FBO
Linux, x64, 64bit (optimized), Oracle 11g on Apr 23 2012 08:32:14
Copyright (C) 1995, 2012, Oracle and/or its affiliates. All rights reserved.
GGSCI (redhat6) 1> create subdirs
以上配置须SOURCE和TARGET端都进行
二、配置源(SOURCE)数据库
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。
2.1 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。
(1)归档模式
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/app/oracle/archlog
Oldest online log sequence 12
Next log sequence to archive 14
Current log sequence 14
SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;
LOG_MODE SUPPLEME FOR
------------ -------- ---
ARCHIVELOG YES NO
(2)强制日志
SQL> alter database force logging;
Database altered.
(3)附加日志
SQL>alter database add supplemental log data;
SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;
LOG_MODE SUPPLEME FOR
------------ -------- ---
ARCHIVELOG YES YES
2.2禁用RecycleBin(oracle10g ogg需要禁用，oracle11g ogg不要求)
SQL> alter system set recyclebin=off scope=spfile;
System altered.
SQL> shutdown immediate
2.3创建存放DDL信息的用户并授权
SQL> create user ggate identified by ggate default tablespace users temporary tablespace temp;
User created.
SQL> grant connect,resource to ggate;
Grant succeeded.
SQL> grant execute on utl_file to ggate;
Grant succeeded.
[oracle@redhat6 ~]$ cd $GGATE
[oracle@redhat6 ggate]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Mon Dec 9 04:55:44 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> @marker_setup.sql; ---输入之前创建的用户ggate
SQL> @ddl_setup.sql; ---输入之前创建的用户ggate
SQL> @role_setup.sql; ---输入之前创建的用户ggate
SQL>grant GGS_GGSUSER_ROLE to ggate;
SQL>@ddl_enable.sql;
三、测试OGG
3.1 分别在SOURCE DB和TARGET DB上创建测试用户
SOURCE DB:
SQL> create user source identified by oracle default tablespace users temporary tablespace temp;
User created.
SQL> grant connect,resource,dba to source;
Grant succeeded.
TARGET DB:
SQL> create user targer identified by oracle default tablespace tbs_hjj temporary tablespace temp;
User created.
SQL> grant connect,resource,dba to targer;
Grant succeeded.
3.2 在SOURCE和TARGET分别配置MANAGER
远端和目标端都做同样的操作
GGSCI (redhat6) 1> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER STOPPED
GGSCI (redhat6) 2> edit params mgr
GGSCI (redhat6) 3> start mgr
Manager started.
GGSCI (redhat6) 4> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
3.3 配置SOURCE DB的复制队列
连接到数据库，测试连接：
GGSCI (redhat6) 5> dblogin userid [ggate@hjj,password](mailto:ggate@hjj,password) ggate
Successfully logged into database.
增加一个抽取extract:
GGSCI (redhat6) 6> add extract ext1,tranlog,begin now
EXTRACT added.
GGSCI (redhat6) 7> add exttrail /u01/ogg/dirdat/lt,extract ext1
EXTTRAIL added.
GGSCI (redhat6) 8> edit params ext1
extract ext1
userid [ggate@hjj,password](mailto:ggate@hjj,password) ggate
rmthost redhat6,mgrport 7809
rmttrail /u01/ogg/dirdat/lt
ddl include mapped objname source.*;
table source.*;
GGSCI (redhat6) 2> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EXT1 00:00:00 00:00:10
3.4 配置TARGET DB的同步队列
GGSCI (redhat6) 2> edit params ./GLOBAL
GGSCHEMA ggate
CHECKPOINTTABLE ggate.checkpoint
GGSCI (redhat6) 3> dblogin userid [ggate@hjj,password](mailto:ggate@hjj,password) ggate
Successfully logged into database.
GGSCI (redhat6) 4> add checkpointtable ggate.checkpoint
Successfully created checkpoint table ggate.checkpoint.
创建同步队列
GGSCI (redhat6) 1> add replicat rep1,exttrail /u01/ogg/dirdat/lt,checkpointtable ggate.checkpoint
REPLICAT added.
GGSCI (redhat6) 5> edit params rep1
replicat rep1
ASSUMETARGETDEFS
userid [ggate@hjj,password](mailto:ggate@hjj,password) ggate
discardfile /u01/ogg/dirdat/rep1_discard.txt,append, megabytes 10
DDL
map source.*, target targer.*;
3.5 开启同步
(1)SOURCE端：
GGSCI (redhat6) 10> start extract ext1
Sending START request to MANAGER ...
EXTRACT EXT1 starting
GGSCI (redhat6) 11> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EXT1 00:07:38 00:00:00
(2)TARGET端：
GGSCI (redhat6) 3> start replicat rep1
Sending START request to MANAGER ...
REPLICAT REP1 starting
GGSCI (redhat6) 4> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EXT1 00:00:00 00:00:05
REPLICAT RUNNING REP1 00:00:00 00:00:01
3.6 测试数据复制
(1)SOURCE DB:
[oracle@redhat6 ogg]$ sqlplus source/oracle
SQL*Plus: Release 11.2.0.3.0 Production on Mon Dec 9 20:09:11 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> create table hjj as select * from sys.all_users;
Table created.
(2)TARGET DB 查看数据同步情况:
[oracle@redhat6 ogg]$ sqlplus targer/oracle
SQL*Plus: Release 11.2.0.3.0 Production on Mon Dec 9 20:09:26 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select count(*) from hjj;
COUNT(*)
----------
12
在SOURCE端执行：
SQL> insert into hjj select * from sys.all_users;
12 rows created.
SQL> commit;
Commit complete.
在TARGET查看同步情况
SQL> select count(*) from hjj;
COUNT(*)
----------
24
Oracle到Oracle的单向复制配置完成。
