CENTOS6.5一步一步安装OGG实现DML DDL单向复制及服务器故障恢复

一、环境描述

操作系统版本: CentOS-6.5-x86_64

系统分区：

sda:40G

sda1:500M /boot EXT4

sda2: 39.5G /为LVM,包括:lv_swap 4G,lv_root 35.6G

源端[A]系统数据库 IP: 192.168.81.211

目标端[B]系统数据库 IP: 192.168.81.212

Vip:192.168.81.210（规划中，暂未使用）

数据库版本: oracle_112030_Linux-x86-64

Oracle Base:/u01/app/oracle

Software location: /u01/app/oracle/11.2.0/dbhome

Inventory directory:/u01/app/oraInventory

Clobal database name: orcl

SID:ogg1

sys/system/sysman/dbsnmp:123456

数据文件存放路径:/u01/oradata/

OGG 版本: ogg112101_fbo_ggs_Linux_x64_ora11g_64bit

说明：

# 提示符表示用户root环境下， $提示符表示用户oracle环境下。

源服务器=通俗的主服务器、目标服务器=通俗的备用服务器

建议：

系统、数据库软件在一组物理盘，存储的数据在另一组物理盘。

二、AB Linux安装

【A、B端】Linux安装：

Disc Found -> Skip -> next -> next -> next

Basic storage devices -> next -> yes,discard any data -> next

time zone: Chongqing -> next

password: 123456 -> next -> Use Anyway

Replace existing Linux system -> next -> Write changes to disk

选 Database server 点 Customize now -> next

Databases: 勾掉 2 Mysql 和 2 PostgreSQL

development:除了eclipse外全选

desktops:desktop

Languages:chinese support

Load Balancer

-> next

reboot

create user: NO

三、AB DB安装

【A、B端】DB安装：

root登陆系统

启动网卡：[用光标、TAB键切换选择项、回车键确认]以A为例，B只要修改为192.168.81.212，其他一样：

#setup->network configuration->Run Tool->Device configuration->eth0 (eth0) -...->

│ Name eth0________________ │

│ Device eth0________________ │

│ Use DHCP [ ] │ <- 去掉“*”

│ Static IP 192.168.81.211______ │ <- IP

│ Netmask 255.255.255.0_______ │ <- 掩码

│ Default gateway IP 192.168.81.1________ │ <- 默认网关

->ok->save->save&Quit->Quit

#ifdown eth0

#ifup eth0

#ifconfig

eth0 Link encap:Ethernet HWaddr 00:0C:29:94:5A:29

inet addr:192.168.81.211 Bcast:192.168.81.255 Mask:255.255.255.0

测试：insert delete update OK!!

小心由于AB数据不一致，导致ogg B replicat 进程 abended

所以，最好先停业务、停OGG服务，导A数据到B，然后再启动Bogg、Aogg、业务

五、DDL单向复制

【DDL单向A->B复制】参考“为已经运行的GoldenGate开启DDL选项”

1. 源端支持DDL复制运行脚本

2. 修改源端extract进程的params文件

3. 修改目标端replicat进程的params文件

4. 测试

1.分别停止source、target端的OGG进程

stop *

stop mgr

2.source端抽取进程参数添加DDL选项

GGSCI (node3) 43> edit params ext_01

...

DDL INCLUDE ALL

DDLOPTIONS ADDTRANDATA, REPORT

...

3.target端复制进程添加DDL选项

GGSCI (single) 19> edit params rep_01

...

DDL INCLUDE MAPPED

DDLOPTIONS REPORT

...

4. 为OGG用户显示添加权限

grant dba to goldengate;--可省

grant create table,create sequence to goldengate;--可省

@role_setup.sql

GRANT GGS_GGSUSER_ROLE TO goldengate;

@marker_setup.sql

name:goldengate

@ddl_setup.sql

name:goldengate

@ddl_enable.sql

[email protected]_disable.sql

[email protected]_remove.sql

分别开启source、target端各个进程

start mgr

start *

测试：

source

create table tt as select * from aaa;

target

desc tt;

source

ALTER TABLE tt ADD cc varchar2(4) default ‘zz‘;

target

desc tt;

source

ALTER TABLE aaa ADD cc varchar2(4) default ‘zz‘;

target

select * from aaa;

OK!!

六、问题场景描述

源服务器A出问题[如系统崩溃、数据库崩溃、磁盘坏等]切换操作：

把问题服务器A修复后，设置为目标服务器B，把之前的目标服务器B设置为源服务器A。AB的IP等系统设置不变。

目标服务器B出问题，直接按照新装目标服务器搭建即可。

假设A服务器192.168.81.211崩溃的恢复【恢复后当目标机B用】步骤：

1.恢复A.211后当目标B.211机用

2.设置原来的目标B.212机为现在的源端A.212机用

3.依据SCN从212导数据到211，或者直接从A完全导数据到B

4.启动211、212的OGG服务

注意：

A、B数据不同，容易导致OGG服务挂起！！！

在212数据导出之前，必须关闭数据对外服务，待数据导出开始后，启动源端OGG的各服务后，才能启动源端数据的对外服务；在目的端211，必须等数据导入后，才能启动OGG各服务。否则会因为中间产生无法同步的数据，导致生产中OGG
DOWN机各服务挂起。

或者：断掉数据服务，导数据A->B，开A、B的OGG各个服务，提供数据服务。

七、恢复A为目标服务器

192.168.81.211原来的源端A.211机设置为目标【B.211】端：

1、按“myDB20160417”文档安装系统、数据库【IP、SID等不变，还为A.211的】

$scp ./oracle ./dbSet.sh [email protected]:/root

#bash ./dbSet.sh
