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

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。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。
(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;
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 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 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 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 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。
