Oracle GoldenGate配置和部署

1.环境介绍

主库：

cai/cai@192.168.10.166/TEST

备库：

cai/cai@192.168.10.168/TEST

注意：此处笔者用一样的环境是因为方便创建环境，和OGG没有关系！

2.用户和环境介绍

笔者此处用oracle用户配置，笔者不喜欢多用户，否则太邋遢！

3.安装ogg（主备都做）

[root@master ~]# su - oracle
[oracle@master ~]$ mkdir /oracle/ogg
[oracle@master ~]$ cd /oracle/ogg/
[oracle@master ogg]$ tar xvf /usr/src/fbo_ggs_Linux_x64_ora10g_64bit.tar
oracle@master 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, x64, 64bit (optimized), Oracle 10g on Apr 23 2012 07:30:46

Copyright (C) 1995, 2012, Oracle and/or its affiliates. All rights reserved.

GGSCI (master) 1> create subdirs

Creating subdirectories under current directory /oracle/ogg

Parameter files                /oracle/ogg/dirprm: already exists
Report files                   /oracle/ogg/dirrpt: created
Checkpoint files               /oracle/ogg/dirchk: created
Process status files           /oracle/ogg/dirpcs: created
SQL script files               /oracle/ogg/dirsql: created
Database definitions files     /oracle/ogg/dirdef: created
Extract data files             /oracle/ogg/dirdat: created
Temporary files                /oracle/ogg/dirtmp: created
Stdout files                   /oracle/ogg/dirout: created
create subdirs

至此OGG安装完成

4.配置ogg（主备都做）

[oracle@master ogg]$ pwd
/oracle/ogg
[oracle@master ogg]$ sqlplus / as sysdba

5.OGG进程介绍

MANAGER：进程调度和传输

EXTRACT：负责从源库获取数据（抽取进程）

REPLICAT：负责将数据应用到备库（队列进程）

6.配置OGG manager（主备都做）

GGSCI (slave) 3> edit params mgr   //编辑mgr的参数文件

GGSCI (slave) 4> view params mgr  //查看mgr的配置信息

PORT 7809

GGSCI (slave) 3> start manager   //启动manager服务

Manager started.
GGSCI (slave) 1> info all  //查看所有服务的状态

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

7.主库配置抽取进程

GGSCI (master) 1> dblogin userid ogg, password ogg

GGSCI (master) 1> add extract ext1,tranlog, begin now

GGSCI (master) 1> add exttrail /oracle/ogg/dirdat/lt, extract ext1

GGSCI (master) 1> edit params ext1GGSCI (master) 2> view params ext1extract ext1   //extract进程名字ext1的配置参数userid ogg, password ogg //登录本地库的用户名和密码rmthost 192.168.10.168, mgrport 7809  //远程manager的地址和portrmttrail /oracle/ogg/dirdat/lt   //exttrail的位置ddl
include mapped objname cai.*;table cai.*; //用户的表

8.配置备库的队列进程

GGSCI (slave) 1> edit params ./GLOBAL
GGSCI (slave) 2> dblogin userid ogg, password ogg
Successfully logged into database.
GGSCI (slave) 3> add checkpointtable ogg.chkpoint
Successfully created checkpoint table ogg.chkpoint.
GGSCI (slave) 4> add replicat rep1,exttrail /oracle/ogg/dirdat/lt, checkpointtable ogg.checkpoint
REPLICAT added.

GGSCI (slave) 5> edit params rep1
GGSCI (slave) 2> view params rep1
replicat rep1
ASSUMETARGETDEFS
HANDLECOLLISIONS
userid ogg,password ogg
discardfile /oracle/ogg/dirdat/rep1_discard.txt,append, megabytes 10
DDL
map cai.*, target cai.*;
GGSCI (slave) 3> start rep1
GGSCI (slave) 3> info all
Program     Status      Group       Lag at Chkpt  Time Since Chkpt
MANAGER     RUNNING                                              //manager正在运行
REPLICAT    RUNNING     REP1        00:00:00      00:00:00       //replicat正在运行

9.主库启动抽取，查看进程状态

GSCI (master) 3> start ext1
GGSCI (master) 3> info all  
ram     Status      Group       Lag at Chkpt  Time Since Chkpt
MANAGER     RUNNING                                           
EXTRACT     RUNNING     EXT1        00:00:00      00:00:04

/oracle/ogg
[oracle@slave ogg]$ ll ggserr.log
-rw-rw-rw-. 1 oracle oinstall 3264 Nov 20 02:35 ggserr.log

注意：如果服务起不来，或者有问题，可以查看次日值

同步故障可以查看

[oracle@slave dirdat]$ pwd
