① RAC环境下配置OGG单向同步
注意：本篇BLOG中代码部分需要特别关注的地方我都用***背景和红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方。

一.4.1.1 配置listener
配置监听，加入对ASM的动态注册：

Listener LISTENER is running on node(s): node1,node2
[oracle@node1 ~]$ lsnrctl services

一.4.2.1 安装ACFS
我们首先来安装ACFS,即ASM Cluster File System，相关知识不多解释，而安装ACFS也有很多种办法，这里我们采用命令行的方式来安装ACFS，我们在节点一上操作:
a、root用户手工加载驱动：ASM volume driver，acfsload为grid用户下的命令
[root@node1 ~]# acfsload -s
acfsload: ACFS-9228: usage: acfsload {start|stop} [-s]
[root@node1 ~]# acfsload start
ACFS-9327: Verifying ADVM/ACFS devices.
ACFS-9322: done.
[root@node1 ~]#
b、创建磁盘组，也可以不用创建磁盘组，后边采用已经存在的磁盘组来创建卷组，我们这里就不再重新创建磁盘组了
c、创建asm卷
[root@node1 ~]# su - grid
[grid@node1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.1.0 Production on Thu Jun 11 14:16:13 2015
SQL> alter diskgroup DATA add volume acfsvol1 size 1G;
Diskgroup altered.
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
[grid@node1 ~]$ ll /dev/asm
total 0
brwxrwx--- 1 root asmadmin 252, 118786 Jun 11 14:16 acfsvol1-232
brwxrwx--- 1 root asmadmin 252, 118785 Jun 11 13:45 vol01-232
d、创建acfs挂载目录，在rac1和rac2节点都执行
[root@node1 ~]# mkdir -p /u01/app/acfsmounts/acfsvol1-232
[root@node2 ~]# mkdir -p /u01/app/acfsmounts/acfsvol1-232
e、用mkfs创建文件系统
[root@node1 ~]# /sbin/mkfs -t acfs -n acfs01 /dev/asm/acfsvol1-232
mkfs.acfs: version = 11.2.0.1.0.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/acfsvol1-232
mkfs.acfs: volume size = 1073741824
mkfs.acfs: Format complete.
f、用acfsuit命令注册文件系统
[root@node1 ~]# /sbin/acfsutil registry -a -f /dev/asm/acfsvol1-232 /u01/app/acfsmounts/acfsvol1-232
acfsutil registry: mount point /u01/app/acfsmounts/acfsvol1-232 successfully added to Oracle Registry
g、用mount.acfs命令挂载文件系统
[root@node1 ~]# mount.acfs -o all
[root@node1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 75G 57G 15G 81% /
/dev/sda1 99M 27M 67M 29% /boot
tmpfs 1005M 463M 542M 47% /dev/shm
/dev/asm/vol01-232 1.0G 73M 952M 8% /u01/app/acfsmounts/data_vol01
/dev/asm/acfsvol1-232
1.0G 73M 952M 8% /u01/app/acfsmounts/acfsvol1-232
[root@node1 ~]# ssh node2 "df -h"
root@node2's password:
/dev/sda3 75G 16G 55G 23% /
/dev/sda1 99M 26M 69M 28% /boot
h、改变文件系统属性供oracle使用
[root@node1 ~]# chown oracle.asmadmin /u01/app/acfsmounts/acfsvol1-232
[root@node1 ~]# ll -d /u01/app/acfsmounts/acfsvol1-232
drwxrwx--- 4 oracle asmadmin 4096 Jun 11 14:24 /u01/app/acfsmounts/acfsvol1-232
[root@node1 ~]# ssh node2 "ls -ld /u01/app/acfsmounts/acfsvol1-232"
一.4.2.2 acfs上安装ogg，acfs用来存放ogg的安装目录，便于集群件的共享，在10g上部署可以选择ocfs2
首先上传ogg软件到/TMP目录下：
<a href="http://s3.51cto.com/wyfs02/M01/6E/7C/wKiom1V-LjLhhg-sAAB6oy_nkxU798.jpg"></a>
2个节点均配置环境变量，加入如下参数：
export OGG_HOME=/u01/app/acfsmounts/acfsvol1-232/gg11
export PATH=$OGG_HOME:$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$OGG_HOME:$ORACLE_HOME/lib:$LD_LIBRARYPATH
alias ggsci='rlwrap ggsci'
[oracle@node1 gg11]$ source ~/.bash_profile
[oracle@node1 gg11]$ echo $OGG_HOME
/u01/app/acfsmounts/acfsvol1-232/gg11
[oracle@node1 gg11]$
[oracle@node2 ~]$ source ~/.bash_profile
[oracle@node2 ~]$ echo $OGG_HOME
[oracle@node2 ~]$
开始在节点一安装OGG软件：
[root@node1 tmp]# chown oracle.oinstall ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
[root@node1 tmp]# su - oracle
[oracle@node1 tmp]$ unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip

注意进程的启动顺序，先是source和target端的mgr进程，其次是source端的extract进程，target端的replicat进程，最后是source端的extract pump进程
进程安排在最后启动，在启动source端的pump进程之前，如果target端的replicat进程未启动，则会报如下错误：
2012-07-15 13:56:14 ERROR OGG-01033 There is a problem in network communication, a remote file problem, encryption keys for target and source do not match (if using ENCRYPT) or an unknown error. (Remote file used is /vol2/ogg/dirdat/rt000000, reply received is Could not create /vol2/ogg/dirdat/rt000000).
利用start group名称启动各个进程，启动后的情况：
source端：
GGSCI (node1) 1> info all
EXTRACT RUNNING TESTEXT 00:00:00 00:00:03
EXTRACT RUNNING TESTPUMP 00:00:00 00:00:02
target端：
GGSCI (orcltest) 7> info all
REPLICAT RUNNING TESTRPT 00:00:00 00:00:04
确保每个进程都是running状态，如果不是的话就view report 进程名，查看日志解决错误后重新启动进程。

总结：rac环境下配置ogg，基本同单实例无异！重点需要注意的地方有以下几点!
1：使用ASM存储，需要先配置ASM实例的静态注册，同时在tnsnames.ora文件中配置连接串
2：在配置exttract进程中，注意需要配置TRANLOGOPTIONS 参数，输入连接asm实例的凭证
3：在配置exttract进程中，添加tranlog的时候，需要写thread 2
4: 注意进程的启动顺序，先是source和target端的mgr进程，其次是source端的extract进程，target端的replicat进程，最后是source端的extract pump进程
