【该文章主要面向Oracle goldengate初学者的搭建配置，文中删去了不需要的多余参数，让初学者一目了然一学就会】
★适用场景
本文适用于单实例间的单向传输，集群配置和双向传输只需要做不多的改变即可，所以先学会本文打好基础
★实验环境
1。数据库情况
源端 ：11gR2（11.2.0.4）
目标端：11gR2（11.2.0.4）
2.操作系统情况
源端 ：RedHat 6.4 IP:1.1.1.1 已关闭防火墙
目标端：RedHat 6.4 IP:1.1.1.2 已关闭防火墙
★关闭数据库的recyclebin（两节点）
(10g必须，11g可选)同步DDL要求关闭10g中的回收站特性
SQL> alter system set recyclebin=off scope=spfile;
★创建系统OGG用户（两节点）
useradd -g oinstall -G dba oggos
mkdir -p /ogg
chmod 777 -R /ogg
chown -R oggos:oinstall /ogg
echo "oggos"|passwd --stdin oggos
★准备OGG环境变量（两节点）
vi /home/oggos/.bash_profile
export ORACLE_SID=ora11g
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0
export GG_HOME=/ogg
export PATH
export PATH=$ORACLE_HOME/bin:$HOME/bin:$ORACLE_HOME/jdk/bin:$GG_HOME:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$GG_HOME
#AIX下为export LIBPATH=$ORACLE_HOME/lib:$GG_HOME
★配置日志模式（两节点/一节点）
startup force
shut immediate
startup mount
alter database archivelog;
alter database open;
alter database force logging;
alter database add supplemental log data;
》》查看配置结果：
SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;
LOG_MODE SUPPLEME FOR
------------ -------- ---
ARCHIVELOG YES YES
★创建DB OGG用户（两节点）
su - oracle
sqlplus /nolog
conn / as sysdba;
create tablespace ogg datafile '/home/oracle/ogg.dbf' size 10m autoextend on next 10m;
create user ogg identified by ogg default tablespace ogg temporary tablespace TEMP;
grant dba to ogg;
或者常规模式
grant connect,resource to ogg;
grant create session,alter session to ogg;
grant select any dictionary,select any table to ogg;
grant alter any table to ogg;
grant flashback any table to ogg;
grant execute on dbms_flashback to ogg;
★OGG的运行环境脚本（两节点）
cd /ogg
sqlplus / as sysdba
@marker_setup.sql
@ddl_setup.sql
@role_setup.sql
grant ggs_ggsuser_role to ogg;
@ddl_enable.sql
温馨提示：全部输入DB用户名“ogg”即可
★安装OGG软件（两节点）
》》高版本
./runInstaller
》》低版本
GGSCI > create subdirs
温馨提示：这个功能适用于低版本ogg，新版ogg提供图形化安装
