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)

Log Read Checkpoint Oracle Redo Logs

2013-05-14 14:58:05 Thread 1, Seqno 0, RBA 0

SCN 0.0 (0)

Log Read Checkpoint Oracle Redo Logs

2013-05-14 14:58:05 Thread 2, Seqno 0, RBA 0

SCN 0.0 (0)

江苏：

GGSCI (irms156) 1> add extract eorajs, tranlog, begin now,threads 1

EXTRACT added.

GGSCI (irms156) 2> info extract eorajs

EXTRACT EORAGD Initialized 2013-05-1414:58 Status STOPPED

Checkpoint Lag 00:00:00 (updated 00:00:13 ago)

Log Read Checkpoint Oracle Redo Logs

2013-05-14 14:58:05 Thread 1, Seqno 0, RBA 0

SCN 0.0 (0)

Log Read Checkpoint Oracle Redo Logs

2013-05-14 14:58:05 Thread 2, Seqno 0, RBA 0

SCN 0.0 (0)

（2）创建抽取进程参数文件

广东：

GGSCI (irms156) 3> edit params eoragd

EXTRACT EORAGD

USERID system, PASSWORD Lu123456

RMTHOST 10.252.48.155, MGRPORT 7809

RMTTRAIL ./dirdat/gd

TABLE scott.emp;

TABLE scott.dept;

TABLE scott.salgrade;

TABLE scott.bonus;

江苏：

GGSCI (irms156) 3> edit params eorajs

EXTRACT EORAJS

USERID system, PASSWORD Lu123456

RMTHOST 10.252.48.155, MGRPORT 7809

RMTTRAIL ./dirdat/js

TABLE scott.emp;

TABLE scott.dept;

TABLE scott.salgrade;

TABLE scott.bonus;

（3）Define the GoldenGate trail

add thetrail that will store the changes on the target.
广东：
GGSCI (irms156) 8> add RMTTRAIL./dirdat/gd, EXTRACT EORAGD

RMTTRAIL added.

GGSCI(irms156) 9> info rmttrail *

Extract Trail: ./dir/gd

Extract: EORAGD

Seqno: 0

RBA: 0

File Size: 5M

江苏：
GGSCI (irms156) 8> add RMTTRAIL./dirdat/js, EXTRACTEORAJS

RMTTRAIL added.

GGSCI(irms156) 9> info rmttrail *

Extract Trail: ./dir/js

Extract: EORAGD

Seqno: 0

RBA: 0

File Size: 5M

(4)启动抽取进程并验证

广东：

GGSCI (irms156) 10> start extracteoragd

Sending START request to MANAGER ...

EXTRACT EORAGD starting

GGSCI (irms156) 11> info extracteoragd, detail

GGSCI(irms156) 12> view report eoragd

江苏：

GGSCI (irms156) 10> start extracteorajs

Sending START request to MANAGER ...

EXTRACT EORAJS starting

GGSCI (irms156) 11> info extract eorajs, detail

GGSCI (irms156)12> view report eorajs

5、配置目标端检查点表

（1）配置全局参数文件并增加检查点表(checkpoint table)

GGSCI (irms155) 1> edit params./globals

checkpointtablescott.ggschkpt

（2）激活GLOBALS参数文件

直接退出再进入ggsci即可生效。

GGSCI (irms155) 2> exit

（3）增加检查点表

GGSCI (irms155) 1> dblogin useridsystem, password Lu123456

Successfully logged into database.

GGSCI (irms155) 3> addcheckpointtable scott.ggschkpt

Successfully created checkpoint tablescott.ggschkpt.

6、配置目标端变更投递

（1）增加replicat组

广东：

GGSCI (irms155) 5> add replicat roragd, exttrail ./dirdat/gd, checkpointtablescott.ggschkpt

REPLICAT added.

江苏：

GGSCI (irms155) 5> add replicat rorajs, exttrail ./dirdat/js, checkpointtablescott.ggschkpt

REPLICAT added.

与源端的配置保持一致。

（2）创建replicat参数文件

广东：

GGSCI (irms155) 7> edit params roragd

REPLICAT RORAGD

USERID system, PASSWORD Lu123456

HANDLECOLLISIONS

ASSUMETARGETDEFS

DISCARDFILE ./dirrpt/RORAGD.DSC, PURGE

MAP scott.emp, TARGET scott.emp;

MAP scott.salgrade, TARGETscott.salgrade;

MAP scott.bonus, TARGET scott.bonus;

MAP scott.dept, TARGET scott.dept;

江苏：

GGSCI (irms155) 7> edit params rorajs

REPLICAT RORAJS

USERID system, PASSWORD Lu123456

HANDLECOLLISIONS

ASSUMETARGETDEFS

DISCARDFILE ./dirrpt/RORAJS.DSC, PURGE

MAP scott.emp, TARGET scott.emp;

MAP scott.salgrade, TARGETscott.salgrade;

MAP scott.bonus, TARGET scott.bonus;

MAP scott.dept, TARGET scott.dept;

（3）启动replicat进程

广东：

GGSCI (irms155) 8> start replicatroragd

Sending START request to MANAGER ...

REPLICAT RORAGD starting

GGSCI (irms155) 9> info replicat roragd

REPLICAT RORAGD Last Started 2013-05-14 15:39 Status RUNNING
