1、GG组件及其功能简介：
manager进程：总管其他所以进程及处理相应GGSCI命令。
capture进程：从源端的联机日志文件或归档日志文件抓取commit的信息。
source trail文件：capture进程从日志文件挖掘出来的数据，存储在source trail文件中。该文件承载数据，用于发送到目标端。文件可以加密、可压缩处理。
data pump进程：将源端产生的source trail文件发送到目标端。
collector进程：收集data pump进程从源端传送过来的数据信息，根据txtract进程配置情况自动启动，所以一般不用关注。
remote trail进程：collector接收的数据写入目标端trail文件。
replicat进程：按照trail file文件里记录的顺序应用remote trail文件中的数据信息到目标库。
checkpoint：保证GG数据的一致性，完整性，GG断点续传既依靠的检查点信息。有两种方式存储checkpoint信息，文件形（源GG的extract进程必须使用此种模式）式以及数据库表（推荐目标GG端的replicat进程检查点存放在表中）中。
2、环境信息：
源端：
主机名：dbking01 IP:192.168.100.42 数据库：dbking
目标端：
主机名：dbking02 IP:192.168.100.43 数据库：dbking
GG组名称规划：
manager进程名称：mgr
extract组：extdbk01
data pump组：dtpdbk01
replicat组：repdbk02
在此次部署中也是需要部署以上四组进程及其相应的参数文件。
3、安装GG软件：
1）创建管理GG用户：
[root@dbking01 mnt]# id oracle
uid=110(oracle) gid=110(oinstall) groups=110(oinstall),111(dba)
[root@dbking01 mnt]# useradd -g oinstall ggsrc
配置GG环境变量：
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=dbking
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export GG_HOME=/u01/app/ggsrc/112101
export PATH=$GG_HOME:$PATH:$HOME/bin
2）创建用户并解压GG软件：
[root@dbking01 mnt]# mkdir -p /u01/app/ggsrc/
[root@dbking01 ggsrc]# pwd
/u01/app/ggsrc
[root@dbking01 ggsrc]# unzip /mnt/ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[root@dbking01 ggsrc]# mkdir 112101
[root@dbking01 ggsrc]# cd 112101
[root@dbking01 112101]# tar -xvf ../fbo_ggs_Linux_x64_ora11g_64bit.tar
3）GG环境的初始化：
验证GGSCI可以登录并且可以登录相应数据库：
[root@dbking01 112101]# chown -R ggsrc:oinstall /u01/app/ggsrc/
[root@dbking01 112101]# su - ggsrc
[ggsrc@dbking01 ~]$ cd /u01/app/ggsrc/112101/
[ggsrc@dbking01 ~]$ ggsci

Stdout files /u01/app/ggsrc/112101/dirout: created
GGSCI (dbking01) 2>
4）配置manager进程：
配置参数文件：
GGSCI (dbking01) 1> edit param mgr
port 7809 --指定GG运行端口号，mgr文件唯一必须的参数
DYNAMICPORTLIST 7802-7820 --进程间动态分配的端口号段
autorestart extract *,waitminutes 2,resetminutes 5 --表示自动重启extract组，每2分尝试重启一次，可以重复尝试重启5次
PURGEOLDEXTRACTS /u01/app/ggsrc/112101/dirdat/* --自动清除trail文件
启动manager进程：
GGSCI (dbking01) 2> info mgr
Manager is DOWN!
GGSCI (dbking01) 3> start mgr
Manager started.
GGSCI (dbking01) 4> info mgr
Manager is running (IP port dbking01.7809).
至此，linux上源端的GG安装完成。

4、配置点对点单向复制GG
单向复制要求对被复制数据只能在源数据库里修改，目标数据库一端应该是只读的，但是我们不能使用命令对目标端强制只读，那么replicat进程也无法应用复制了，因此一般都是在应用程序逻辑来做保证。
1）为source端和target端数据库创建GG管理用户
>source端创建用户：
SQL> create tablespace ogg_tbs datafile '/u01/app/oracle/oradata/dbking/ogg_tbs01.dbf' size 200m autoextend on next 50m maxsize 10g;
Tablespace created.
SQL> create user ggs identified by oracle default tablespace ogg_tbs account unlock;
User created.
SQL> grant connect,resource,dba to ggs;
Grant succeeded.
SQL> grant select any table to ggs;
Grant succeeded.
SQL> grant select any dictionary to ggs;
Grant succeeded.
>target端创建用户：
SQL> create tablespace ogg_tbs datafile '/u01/app/oracle/oradata/dbking/ogg_tbs01.dbf' size 200m autoextend on next 50m maxsize 10g;
Tablespace created.
SQL> create user ggt identified by oracle default tablespace ogg_tbs account unlock;
User created.
SQL> grant connect,resource,dba to ggt;
Grant succeeded.
SQL> grant select any table to ggt;
Grant succeeded.
SQL> grant select any dictionary to ggt;
Grant succeeded.
源端使用ggs这个用户，目标端使用ggt这个用户参与环境的管理。确保两个用户可以在各自环境中成功登录：
GGSCI (dbking01) 1> dblogin userid ggs,password oracle;
Successfully logged into database.
GGSCI (dbking02) 1> dblogin userid ggt,password oracle;
Successfully logged into database.
2）source DB基本配置：
>在source DB上启动数据库级补充日志
SQL> select name,supplemental_log_data_min from v$database;
NAME SUPPLEMENTAL_LOG_DATA_MI
--------------------------- ------------------------
DBKING NO
SQL> alter database add supplemental log data;
Database altered.
SQL> select name,supplemental_log_data_min from v$database;
NAME SUPPLEMENTAL_LOG_DATA_MI
--------------------------- ------------------------
DBKING YES
>source DB设置为归档模式：
SQL> select name,log_mode from v$database;
NAME LOG_MODE
--------------------------- ------------------------------------
DBKING ARCHIVELOG
>source DB设置为force logging模式：
SQL> select name,force_logging from v$database;
NAME FORCE_LOG
--------------------------- ---------
DBKING NO
SQL> alter database force logging;
Database altered.
SQL> select name,force_logging from v$database;
NAME FORCE_LOG
--------------------------- ---------
DBKING YES
>导入source DB复制方案:复制整个schema
[oracle@dbking01 ~]$ impdp system/oracle directory=data_pump_dir dumpfile=OA_3502_20160607.dmp schemas=oa_3502 transform=oid:n
SQL> alter user oa_3502 identified by oracle account unlock;
User altered.
SQL> select count(*) from tab;
COUNT(*)
-------------
1412
>为数据库schemas下表对象启用表级别补充日志：
GGSCI (dbking01) 1> dblogin userid ggs,password oracle
Successfully logged into database.
GGSCI (dbking01) 2> add trandata oa_3502.*
Logging of supplemental redo data enabled for table OA_3502.ACT_GE_BYTEARRAY.
2016-07-22 09:45:02 WARNING OGG-00869 No unique key is defined for table 'ACT_GE_PROPERTY'. All viable columns will be used to represent the key, but may not guarantee uniqueness. KEYCOLS may be used to define the key.

Logging of supplemental redo data enabled for table OA_3502.ACT_HI_ACTINST.
... ...
GGSCI (dbking01) 3> info trandata oa_3502.*
3）target DB基本配置：
>考虑两个问题：source db是否存在级联更新的触发器对象；是否使用检查点表。
target db禁用级联更新的触发器对象方法：
数据库级别禁用触发器：SQL>alter table ... disable constraint;
SQL>alter trigger ... disable;
GG11提供的方法：DBOPTIONS suppresstriggers
checkpoint table设置：两种做法“共用或专用”。
>共用checkpoint table创建方法：本测试使用方法。
[ggsrc@dbking02 112101]$ vi $GG_HOME/GLOBALS
CheckPointTable ggt.chkpt
ggsci中做如下操作：
GGSCI (dbking02) 1> dblogin userid ggt,password oracle
Successfully logged into database.
GGSCI (dbking02) 2> add checkpointtable
No checkpoint table specified, using GLOBALS specification (ggt.chkpt)...
Successfully created checkpoint table ggt.chkpt.
GGSCI (dbking02) 3> info checkpointtable ggt.chkpt
Checkpoint table ggt.chkpt created 2016-07-21 19:19:01.
数据库级别查看表信息：
SQL> select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ --------------------- ----------
CHKPT TABLE
CHKPT_LOX TABLE
>replicat级别的checkpointable：
实现语法：GGSCI>add replicat rb,exttrail dirdat/rp,checkpointtable ggt.rbcpt
注意点：使用此种方法需要手工创建ggt.rbcpt表和ggt.rbcpt_lox表。
4）配置extract进程：
>编辑extract进程参数文件：
GGSCI (dbking01) 1> edit params extdbk01
Extract extdbk01 --extract参数的作用是定义extract组的组名，名字最长8个字符。
SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) --GG继承OS的环境变量，也可以在GG中定义环境变量覆盖OS的变量，此处使用的就是setenv参数
USERID ggs@dbking,PASSWORD oracle --用来指定数据库的用户名及其密码，此处密码使用明文，也可以使用encrypt password参数对密码加密处理
--RMTHOST dbking02,MGRPORT 7809 --定义目标端位置及其端口号
--RMTTASK REPLICAT,GROUP repdbk02 --定义目标端的replicat进程及其组名字
ExtTrail dirdat/sp --exttrail参数指定source trail文件存放位置（此处使用默认路径，也可以指定绝对路径），其中sp是生成trail文件的前缀
Table oa_3502.*； --定义GG要抓取源数据的表，必须以；结尾
*注意参数文件中参数的排列顺序：其中extract参数必须放在第一位；exttrail参数必须放在table参数前面。
保存退出，dirprm/目录下会生成相应参数文件：
[ggsrc@dbking01 dirprm]$ pwd
/u01/app/ggsrc/112101/dirprm
[ggsrc@dbking01 dirprm]$ ll
total 12
-rw-rw-rw-. 1 ggsrc oinstall 194 Jul 22 10:52 extdbk01.prm
-rwxr-x---. 1 ggsrc oinstall 53 Apr 23 2012 jagent.prm
-rw-rw-rw-. 1 ggsrc oinstall 135 Jul 22 10:12 mgr.prm
>创建extract服务进程
GGSCI (dbking01) 1> add extract extdbk01,tranlog,begin now
EXTRACT added.
注解：add extract就是创建了extdbk01组，tranlog定义用日志系统作为抓取操作数据源，begin指定抓取操作开始时间，此处指定立即开始，也可以使用begin yyyy-mm-dd的形式指定抓取时间。
GGSCI (dbking01) 2> add exttrail dirdat/sp,extract extdbk01,megabytes 100
EXTTRAIL added.
注解：add exttrail指定创建source trail文件，并和extdbk01组关联，指定source trail文件最大大小为100m

5）配置data pump进程
>编辑参数文件：
GGSCI (dbking01) 1> edit params dtpdbk01
Extract dtpdbk01 --extract参数的作用是定义extract组的组名，名字最长8个字符。
PassThru --透传，当源库与目标库数据库结构完全一致时，可以采用透传的方式。否则需要采用nopassthru方式，此时需要定义userid和password参数。
rmthost dbking02,mgrport 7809 --定义目标端位置及其端口号
rmttrail dirdat/rp --定义remote trail文件的前缀
table oa_3502.*； --定义要传输的数据表，可以使用通配符
注：该进程不与数据库打交道，所以没有配置环境变量，既采用passthru方式传输数据。
