Oracle GoldenGate学习之--基本概念和配置(2)
一、Oracle OGG下载：
http://www.oracle.com/technetwork/cn/middleware/goldengate/downloads/index.html
二：OGG安装（RedHat EL6)
系统架构：
Test Environment：
| Item | Source System | Target System |
| Platform | RedHat EL6 | RedHat EL6 |
| HostName | ogg | rh7 |
DataBase Version | Oracle 11.2.0.1.0 | Oracle 11.2.0.1.0 |
| Character Set | zhs16gbk | zhs16gbk |
| ORACLE_SID | prod | prod |
| Listener | linstener/1521 | linstener/1521 |
| GoldenGate User | ogg | ogg |
1、检测安装环境
[oracle@rh7 ogg]$ uname -a
Linux rh7.cuug.net 2.6.32-71.el6.i686 #1 SMP Wed Sep 1 01:26:34 EDT 2010 i686 i686 i386 GNU/Linux
[oracle@rh7 ogg]$ arch
i686
2、安装OGG软件
[oracle@rh7 ogg]$ mkdir -p /u01/ogg
[oracle@rh7 ogg]$ ls -l
total 85912
-rw-r----- 1 oracle oinstall 87966150 Sep 10 11:33 ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip
注意：
下载的OGG 11g版本有32位和64位，如果在操作系统为32位，安装64位的OGG，将出现以下错误
“不可执行的二进制文件”
[oracle@rh7 ogg]$ unzip ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip

3、执行ggsci脚本，建立相关目录
[oracle@rh7 ogg]$ ./ggsci Oracle GoldenGate Command Interpreter for Oracle Version 11.2.1.0.1 OGGCORE_11.2.1.0.1_PLATFORMS_120423.0230_FBO Linux, x86, 32bit (optimized), Oracle 11g on Apr 23 2012 08:09:25 Copyright (C) 1995, 2012, Oracle and/or its affiliates.

GGSCI>create subdirs
--不需要指定路径，默认在当前目录下（所以进入ggsci的时候，一定要在gg的当前目录）
新建出来的目录有：
name Purpose
--dirchk Checkpoint files存放检查点（Checkpoint）文件 (和Oracle的checkpoint含义不同，如oralce的一个实例失败，从最近一次的checkpoint开始recorver, oracle的一次 checkpoint是让dbwrt进程把被修改的数据从数据缓冲区中写入数据文件。而OGG的checkpoint是OGG捕捉了很多事务日志，哪些被传输了，哪些未被传输。每隔一段时间，执行一次checkpoint,之前的所有数据都要传送过去。如果soure or target db断电了，那下次启动的时候，就要支持断点续传，那那个断点位置就是最后一次OGG执行checkpoint的位置)
--dirdat GoldenGate trails, 存放Trail与Extract文件
--dirdef Data Definition files,过DEFGEN工具生成的源或目标的数据定义文件
--dirprm Parameter files, 存放参数文件
--dirpcs Process status files, 存放进程状态文件
--dirrpt Report files, 存放进程报告文件
--dirsql SQL script files,存放SQL脚本文件
--dirtmp Temporary files,当事务所需要的内存超过已分配内存时，缺省存储于此
@至此，OGG在linux下安装基本完成，后面将进入OGG的基本配置
