A库（172.25.0.10）--> B库（172.25.12.11）:
～～～～～～～～～～～
A库与B库都要归档模式:
～～～～～～～～～～～
shut immediate
startup mount
alter database archivelog;
alter database open;
～～～～～～～～～～～～～～～～～
A库与B库都要打开追加日志数据模式:
～～～～～～～～～～～～～～～～～
alter database add supplemental log data;
SQL> select SUPPLEMENTAL_LOG_DATA_MIN from v$database;
SUPPLEME
--------
YES
～～～～～～～～～～～～～～～～
A库与B库都要打开force logging:
～～～～～～～～～～～～～～～～
禁止数据源一方使用nologging加速insert
alter database force logging;
SQL> select force_logging from v$database;
FOR
---
YES
～～～～～～～～～～～～～～～
A库与B库都要创建ogg的管理用户:
～～～～～～～～～～～～～～～
grant
connect,
resource,
unlimited tablespace,
select any dictionary,
select any table,
insert any table,
update any table,
delete any table,
alter any table,
flashback any table
to ggs
identified by ggs;
grant execute on dbms_flashback to ggs;
grant execute on utl_file to ggs;
～～～～～～～～～～～～～～～～～
A库与B库都要安装对应版本的ogg软件:
～～～～～～～～～～～～～～～～～
scp ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip oracle@172.25.0.10:/home/oracle/
mkdir -p /home/oracle/insogg/
unzip /home/oracle/ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip -d /home/oracle/insogg/
mkdir -p /home/oracle/ogg/
tar -xvf /home/oracle/insogg/fbo_ggs_Linux_x64_ora11g_64bit.tar -C /home/oracle/ogg
～～～～～～～～～～～
在环境变标量中增加ogg:
～～～～～～～～～～～
export PATH=$ORACLE_HOME/bin:/home/oracle/ogg:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/home/oracle/ogg:$LD_LIBRARY_PATH
A库与B库，进入ogg安装目录，创建ogg需要的子目录：
cd /home/oracle/ogg
ggsci
GGSCI (install0.example.com) 1> create subdirs
Creating subdirectories under current directory /home/oracle/ogg
Parameter files /home/oracle/ogg/dirprm: already exists
Report files /home/oracle/ogg/dirrpt: created
Checkpoint files /home/oracle/ogg/dirchk: created
Process status files /home/oracle/ogg/dirpcs: created
SQL script files /home/oracle/ogg/dirsql: created
Database definitions files /home/oracle/ogg/dirdef: created
Extract data files /home/oracle/ogg/dirdat: created
Temporary files /home/oracle/ogg/dirtmp: created
Stdout files /home/oracle/ogg/dirout: created
在A库准备测试用的表：
create table scott.e01 as select * from scott.emp;
alter table scott.e01 add constraint pk_e01_empno primary key (empno);
将A库的表导入到B库：
exp scott/tiger tables=e01 file=e01.dmp
scp e01.dmp oracle@172.25.0.11:/home/oracle
imp scott/tiger file=e01.dmp full=y
授予scott用户dba角色:
grant dba to scott;
在A库ogg中添加需要同步的表：
GGSCI (oracle0.example.com) 1> dblogin userid ggs,password ggs
GGSCI (oracle0.example.com) 2> add trandata scott.e01
GGSCI (oracle0.example.com) 3> info trandata scott.e01
A库与B库都要配置ogg的核心管理进程（manager）
vi /home/oracle/ogg/dirprm/mgr.prm
---------------------------------------------
port 7788
userid ggs,password ggs
autorestart extract *,waitminutes 2,retries 5
---------------------------------------------
在源和目标都要端添加checkpoint表:
配置全局参数文件
vi /home/oracle/ogg/GLOBALS
--------------------------------
checkpointtable ggs.checkpoint
--------------------------------
GGSCI (oracle0.example.com) 1> dblogin userid ggs, password ggs
GGSCI (oracle0.example.com) 2> add checkpointtable ggs.checkpoint
在A库配置抽取进程：
编辑配置文件
vi /home/oracle/ogg/dirprm/ext1.prm
----------------------------------------------
extract ext1
userid ggs,password ggs
rmthost 172.25.0.10,mgrport 7788
exttrail /home/oracle/ogg/dirdat/ea
tranlogoptions excludeuser ggs
setenv(ORACLE_SID=orcl)
setenv(NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252)
dynamicresolution
table scott.e01;
----------------------------------------------
添加抽取进程
GGSCI (oracle0.example.com) 2> add extract ext1, tranlog, begin now
添加抽取进程的生成文件
GGSCI (oracle0.example.com) 3> add exttrail /home/oracle/ogg/dirdat/ea,extract ext1
在A库配置投递进程：
vi /home/oracle/ogg/dirprm/pump1.prm
----------------------------------------------
EXTRACT pump1
USERID scott, PASSWORD tiger
RMTHOST 172.25.0.11, MGRPORT 7788
RMTTRAIL /home/oracle/ogg/dirdat/pa
TABLE scott.e01;
----------------------------------------------
在源端增加投递进程
GGSCI (oracle0.example.com) 4> add extract pump1,exttrailsource /home/oracle/ogg/dirdat/ea , begin now
增加投递到远程的文件
GGSCI (oracle0.example.com) 5> add rmttrail /home/oracle/ogg/dirdat/pa ,extract pump1
在B库配置复制进程：
配置目标端的复制进程:
vi /home/oracle/ogg/dirprm/rep1.prm
----------------------------------------------------
replicat rep1
userid ggs,password ggs
assumetargetdefs
discardfile /home/oracle/ogg/dirdat/rep1.dsc,append
MAP scott.e01, TARGET scott.e01;
----------------------------------------------------
增加复制进程
GGSCI (install0.example.com) 2> add replicat rep1,exttrail /home/oracle/ogg/dirdat/pa , nodbcheckpoint
所有需要的参数文件都配置完成，按照顺序启动各个进程:
1.启动A库的管理进程
start mgr
2.启动B库的管理进程
start mgr
3.启动B库的复制进程
start rep1
4.启动A库的抽取进程
start ext1
5.启动A库的投递进程
start pump1
总结:A库和B库都需要管理进程，都需要检查点表
A库:抽取进程【ext1】--> 抽取文件（源节点）【ea】--> 投递进程【pump1】-->投递文件（目标节点）【pa】
B库:复制进程【rep1】--> 源投递过来的文件【pa】
增加DDL支持:
需要禁止recyclebin：
alter system set recyclebin=off scope=spfile;
startup force
purge dba_recyclebin;
A库进入ogg目录再启动sqlplus：
cd /home/oracle/ogg
sqlplus / as sysdba
A库运行脚本1：SQL> @marker_setup.sql
A库运行脚本2：SQL> @ddl_setup.sql
11.2.0.4 bug:
alter trigger sys.ggs_ddl_trigger_before disable;
grant create table,create sequence to ggs;
alter trigger sys.ggs_ddl_trigger_before enable;
A库运行脚本3：SQL> @role_setup.sql
A库运行脚本4：SQL> grant GGS_GGSUSER_ROLE TO ggs;
A库运行脚本5：SQL> @ddl_enable.sql
修改A库抽取进程的配置文件
vi /home/oracle/ogg/dirprm/ext1.prm
----------------------------------------------
extract ext1
userid ggs,password ggs
rmthost 172.25.0.10,mgrport 7788
exttrail /home/oracle/ogg/dirdat/ea
tranlogoptions excludeuser ggs
setenv(ORACLE_SID=orcl)
setenv(NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252)
dynamicresolution
ddl include all
ddloptions addtrandata
table scott.*;
----------------------------------------------
修改A库投递进程配置文件：
vi /home/oracle/ogg/dirprm/pump1.prm
----------------------------------------------
EXTRACT pump1
USERID scott, PASSWORD tiger
RMTHOST 172.25.0.11, MGRPORT 7788
RMTTRAIL /home/oracle/ogg/dirdat/pa
TABLE scott.*;
----------------------------------------------
修改B库复制进程的配置文件
vi /home/oracle/ogg/dirprm/rep1.prm
----------------------------------------------------
replicat rep1
userid ggs,password ggs
assumetargetdefs
discardfile /home/oracle/ogg/dirdat/rep1.dsc,append
ddl include mapped
ddlerror default ignore retryop
MAP scott.*, TARGET scott.*;
----------------------------------------------------
停止A库抽取进程和复制进程
停止B库复制进程
启动A库抽取进程和复制进程
启动B库复制进程
双向复制:
B库:抽取进程【ext2】--> 抽取文件（源节点）【eb】--> 投递进程【pump2】-->投递文件（目标节点）【pb】
A库:复制进程【rep2】-->源投递过来的文件【pb】
