GoldenGate系统二：快速搭建三方单向通信GoldenGate环境
1、环境准备
（1）下载安装包并解压至ORACLE_BASE
（2）修改环境变更
[oracle@irms156ogg]$ vi ~/.bashrc
exportPATH=$ORACLE_HOME/bin:/u01/app/ogg:$PATH
（3）创建子目录
[oracle@irms157 ogg]$ ggsci
GGSCI (irms157) 1> create subdirs
Creating subdirectories under currentdirectory /u01/app/ogg
Parameter files /u01/app/ogg/dirprm: already exists
Report files /u01/app/ogg/dirrpt: created
Checkpoint files /u01/app/ogg/dirchk: created
Process status files /u01/app/ogg/dirpcs: created
SQL script files /u01/app/ogg/dirsql: created
Database definitions files /u01/app/ogg/dirdef: created
Extract data files /u01/app/ogg/dirdat: created
Temporary files /u01/app/ogg/dirtmp: created
Stdout files /u01/app/ogg/dirout: created
注：建议所有Goldengate操作均在Goldengate安装目录下进行。
2、开启管理进程
（1）创建管理进程参数文件
GGSCI (irms156) 1> edit params mgr
port 7809
（2）启动管理器
GGSCI(irms156) 2> start mgr
Managerstarted.
GGSCI(irms156) 3> info mgr
Manager isrunning (IP port irms156.7809).
GGSCI(irms156) 4> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
3、在源端开启补充日志
（1）Oracle-specificinstallation steps
Thefollowing steps are only required when GoldenGate will be capturing data fromthe server. Therefore it is only needed when you are installing GoldenGate forOracle as your <source> environment.
[oracle@irms157 ogg]$ sqlplus /nolog
SQL> conn / as sysdba
Connected.
SQL> alter database add supplementallog data;
Database altered.
SQL> alter system switch logfile;
System altered.
（2）为具体模式对象开启补充日志（Add supplemental logging）
GGSCI (irms156) 9> dblogin useridsystem, password Lu123456;
Successfully logged into database.
GGSCI (irms156) 10> add trandatascott.emp;
ERROR: No viable tables matchedspecification.（注意不要有分号）
GGSCI (irms156) 11> add trandatascott.emp
Logging of supplemental redo dataenabled for table SCOTT.EMP.
GGSCI (irms156) 13> add trandatascott.salgrade
2013-05-14 14:29:47 WARNING OGG-00869 No unique key is defined for table'SALGRADE'. All viable columns will be used to represent the key, but may notguarantee uniqueness. KEYCOLS may beused to define the key.
Logging of supplemental redo dataenabled for table SCOTT.SALGRADE.
GGSCI (irms156) 14> add trandatascott.bonus
2013-05-14 14:30:12 WARNING OGG-00869 No unique key is defined for table 'BONUS'.All viable columns will be used to represent the key, but may not guaranteeuniqueness. KEYCOLS may be used to definethe key.
Logging of supplemental redo dataenabled for table SCOTT.BONUS.
GGSCI (irms156) 15> add trandatascott.dept
Logging of supplemental redo dataenabled for table SCOTT.DEPT.
GGSCI(irms156) 16> info trandata scott.emp
Logging ofsupplemental redo log data is enabled for table SCOTT.EMP.
Columnssupplementally logged for table SCOTT.EMP: EMPNO.
3、数据准备
（1）在目标端创建与源端一样的表
（2）把源端的初始数据导入至目标端
由于本实验采用scott模式，在每个oracle数据库均已默认安装，因此不再需要准备。第2步可使用datapump，goldengatedirect load， sql*loader等方法。
4、配置源端提取
（1）增加抽取组
广东：
GGSCI (irms156) 1> add extracteoragd, tranlog, begin now, threads 1
EXTRACT added.
GGSCI (irms156) 2> info extracteoragd
EXTRACT EORAGD Initialized 2013-05-1414:58 Status STOPPED
Checkpoint Lag 00:00:00 (updated 00:00:13 ago)

江苏：

（2）创建抽取进程参数文件
