CENTOS6.5一步一步安裝OGG實現DML DDL單向復制及服務器故障恢復

一、環境描述

操作系統版本: CentOS-6.5-x86_64

系統分區：

sda:40G

sda1:500M /boot EXT4

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

源端[A]系統數據庫 IP: 192.168.81.211

目標端[B]系統數據庫 IP: 192.168.81.212

Vip:192.168.81.210（規劃中，暫未使用）

數據庫版本: 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

數據文件存放路徑:/u01/oradata/

OGG 版本: ogg112101_fbo_ggs_Linux_x64_ora11g_64bit

說明：

# 提示符表示用戶root環境下， $提示符表示用戶oracle環境下。

源服務器=通俗的主服務器、目標服務器=通俗的備用服務器

建議：

系統、數據庫軟件在一組物理盤，存儲的數據在另一組物理盤。

二、AB Linux安裝

【A、B端】Linux安裝：
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
選 Database server 點 Customize now -> next
Databases: 勾掉 2 Mysql 和 2 PostgreSQL
development:除了eclipse外全選
desktops:desktop
HA
Languages:chinese support
Load Balancer
-> next
reboot
create user: NO

三、AB DB安裝

【A、B端】DB安裝：
root登陸系統
啟動網卡：[用光標、TAB鍵切換選擇項、回車鍵確認]以A為例，B只要修改為192.168.81.212，其他一樣：
#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_______ │ <- 掩碼
│ Default gateway IP 192.168.81.1________ │ <- 默認網關
->ok->save->save&Quit->Quit
#ifdown eth0
#ifup eth0
#ifconfig

測試：insert delete update OK!!
小心由於AB數據不一致，導致ogg B replicat 進程 abended
所以，最好先停業務、停OGG服務，導A數據到B，然後再啟動Bogg、Aogg、業務

五、DDL單向復制

【DDL單向A->B復制】參考“為已經運行的GoldenGate開啟DDL選項”
1. 源端支持DDL復制運行腳本
2. 修改源端extract進程的params文件
3. 修改目標端replicat進程的params文件
4. 測試

1.分別停止source、target端的OGG進程
stop *
stop mgr

2.source端抽取進程參數添加DDL選項
GGSCI (node3) 43> edit params ext_01
...
DDL INCLUDE ALL
DDLOPTIONS ADDTRANDATA, REPORT
...

3.target端復制進程添加DDL選項
GGSCI (single) 19> edit params rep_01
...
DDL INCLUDE MAPPED
DDLOPTIONS REPORT
...
4. 為OGG用戶顯示添加權限

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

GRANT GGS_GGSUSER_ROLE TO goldengate;

測試：
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、問題場景描述

源服務器A出問題[如系統崩潰、數據庫崩潰、磁盤壞等]切換操作：

把問題服務器A修復後，設置為目標服務器B，把之前的目標服務器B設置為源服務器A。AB的IP等系統設置不變。

目標服務器B出問題，直接按照新裝目標服務器搭建即可。

假設A服務器192.168.81.211崩潰的恢復【恢復後當目標機B用】步驟：

1.恢復A.211後當目標B.211機用

2.設置原來的目標B.212機為現在的源端A.212機用

3.依據SCN從212導數據到211，或者直接從A完全導數據到B

4.啟動211、212的OGG服務

注意：

A、B數據不同，容易導致OGG服務掛起！！！

在212數據導出之前，必須關閉數據對外服務，待數據導出開始後，啟動源端OGG的各服務後，才能啟動源端數據的對外服務；在目的端211，必須等數據導入後，才能啟動OGG各服務。否則會因為中間產生無法同步的數據，導致生產中OGG DOWN機各服務掛起。

或者：斷掉數據服務，導數據A->B，開A、B的OGG各個服務，提供數據服務。

七、恢復A為目標服務器

192.168.81.211原來的源端A.211機設置為目標【B.211】端：

1、按“myDB20160417”文檔安裝系統、數據庫【IP、SID等不變，還為A.211的】
