Oracle OGG安装，很简单，监控比较复杂
一、 安装前准备
（1）创建操作系统ogg用户
useradd -u 1003 -goinstall -G dba ogg1
echo ogg:ogg|chpasswd
将oracle环境变量拷贝到ogg ~/.bash_profile
环境变量path 添加$ORACLE_HOME/jdk/bin:$PATH
添加OGG_HOME至~/.bash_profile，添加OGG_HOME 到 LD_LIBRARY_PATH和PATH 中
（2）创建安装目录
mkdir /home/ogg
chown –R ogg:oinstall/home/ogg
二、 软件安装
（1）上传ogg安装介质fbo_ggs_Linux_x64_shiphome.zip
解压后直接安装。
（2）创建ogg表空间和用户
create tablespace oggdatafile '+DATA/enmo10/datafile/ogg01.dbf' size 50M autoextend on;
create user oggidentified by ogg default tablespace ogg;
grant dba to ogg;
（3）打开数据库forcelog 和 supplemental_log_data_min
Select NAME,OPEN_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MINfrom v$database;
alter database forcelogging;
alter database addSUPPLEMENTAL log data;
（4）运行ogg支持的脚本
在ogg安装目录有很多ogg支持脚本，运行如下脚本
sqlplus / as sysdba
@marker_setup.sql
@ddl_setup.sql
@role_setup.sql
@ddl_enable.sql
三、 配置同步
（1）./ggsci 进入管理窗口，配置管理进程mgr
此安装程序为最新版本，mgr可以随安装后直接start，配置安装文件后需重启mgr
GGSCI (dbdream) 8>EDIT PARAMS MGR
加入以下两行内容
PORT 7809
PURGEOLDEXTRACTS /home/ogg/oggsoft/dirdat,USECHECKPOINTS
GGSCI (dbdream) 9> stopmgr
GGSCI (dbdream) 10> startmgr
GGSCI (dbdream) 11> infomgr
dblogin userid ogg,password ogg
（2） 配置初始化数据进程源端EINI_1 目的端RINI_1
配置源端进程EINI_1
GGSCI (dbdream) 11>ADD EXTRACT EINI_1, SOURCEISTABLE
GGSCI (dbdream) 13>EDIT PARAMS EINI_1
--加入以下内容

DISCARDFILE/ogg/dirrpt/RINIaa.dsc, PURGE
MAP oggtst.*, TARGET oggtst.*;
GGSCI (stream) 5> ADDREPLICAT RINI _1, SPECIALRUN.
初始化数据（只需开启源端进程，目的端进程会自动带起）：
GGSCI (dbdream) 14>START EXTRACT EINI_1
Sending START request toMANAGER ...
EXTRACT EINI_1 starting
GGSCI (dbdream) 11>VIEW REPORT EINI_1
（3）配置实时同步进程
源端目的端配置ogg检查点：
GGSCI (stream) 2> EDITPARAMS ./GLOBALS
--加入以下信息
CHECKPOINTTABLEogg.ggschkpt
退出ggsci后重新登录执行：
GGSCI (stream) 4> ADDCHECKPOINTTABLE
No checkpoint tablespecified, using GLOBALS specification (ogg.ggschkpt)...
Successfully createdcheckpoint table ogg.ggschkpt.
源端捕获进程配置EORA_1：
GGSCI (dbdream) 10>EDIT PARAMS EORA_1
--加入以下内容
EXTRACT EORA_1 SETENV(NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
USERID ogg, PASSWORD ogg
EXTTRAIL /home/ogg/oggsoft/dirdat/aaTABLE oggtst.*;
--添加抽取进程和抽取路径
GGSCI (dbdream) 11>ADD EXTRACT EORA_1, TRANLOG, BEGIN NOW

GGSCI (dbdream) 12>ADD EXTTRAIL /home/ogg/oggsoft/dirdat/aa, EXTRACT EORA_1, MEGABYTES 5
EXTTRAIL added.
GGSCI (dbdream) 13>START EXTRACT EORA_1
配置源端pump进程PORA_1
GGSCI (dbdream) 15>EDIT PARAMS PORA_1
--加入以下内容
EXTRACT PORA_1
SETENV(NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
PASSTHRU
RMTHOST 192.168.249.99,MGRPORT 7809
RMTTRAIL /home/ogg/oggsoft/dirdat/pa
TABLE oggtst.*;
TABLE scott.DEPT_OGG;
添加PUMP进程PORA_1到OGG，并指定本地的TRAIL文件。
GGSCI (dbdream) 16>ADD EXTRACT PORA_1, EXTTRAILSOURCE /home/ogg/oggsoft/dirdat/aa
EXTRACT added.
设置remote文件位置
GGSCI (dbdream) 18>ADD RMTTRAIL /home/ogg/oggsoft/dirdat/pa, EXTRACT PORA_1, MEGABYTES 5
RMTTRAIL added.
GGSCI (dbdream) 19>START EXTRACT PORA_1
配置目标端应用进程RORA_1
GGSCI (stream) 5> ADDREPLICAT RORA_1, SPECIALRUN
REPLICAT added.
GGSCI (stream) 7> EDITPARAMS RORA_1
--加入以下内容
REPLICAT RORA_1
