各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：
① RAC环境下管理OGG的高可用
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。

一.2.4 本文简介
本文基于grid来管理OGG软件，主要参考网址为：http://ylw6006.blog.51cto.com/all/470441/16 ，非常感谢斩月大师。
在本文中将介绍在oracle 11g r2 rac环境下使用grid infrastructure来管理ogg服务，在开始之前，请先按照前文的步骤配置好rac（source）同单实例(target)数据库之间的ogg单向同步，同时确保rac数据库各项服务运行正常,同时启动target端的数据库实例和ogg的mgr，replicat进程，source端ogg的mgr，extract，extract dump进程可以关闭！
一.3 实验部分
一.3.1 查看rac各服务是否online，这里3个gsd服务offline属于正常情况！

一.3.2 在source端添加VIP，并赋权限,检查vip是否能正常启动，在本例中运行grid infrastructure的操作系统用户为grid，运行ogg的操作系统用户为oracle
[root@node2 ~]# crsctl stat res -p |grep -ie .network -ie subnet |grep -ie name -ie subnet
NAME=ora.net1.network
USR_ORA_SUBNET=192.168.1.0

一.3.3 配置action脚本，该脚本必须包含start,stop,check,clean,abort几个函数，才能用于后续的grid infrastructure调用，这里把脚本直接放在acfs文件系统上，以便节点间共享
[oracle@node1 gg11]$ chmod +x $OGG_HOME/11gr2_ogg_action.scr
[oracle@node1 gg11]$ ll $OGG_HOME/11gr2_ogg_action.scr
-rwxr-xr-x 1 oracle oinstall 2695 Jun 11 17:13 /u01/app/acfsmounts/acfsvol1-232/gg11/11gr2_ogg_action.scr

#right environment settings to be able to connect to the database
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db1
#specify delay after start before checking for successful start
start_delay_secs=5
#Include the GoldenGate home in the library path to start GGSCI
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:${OGG_HOME}:${LD_LIBRARY_PATH}
#check_process validates that a manager process is running at the PID
#that GoldenGate specifies.
check_process () {
if ( [ -f "${OGG_HOME}/dirpcs/MGR.pcm" ] )
then
pid=`cut -f8 "${OGG_HOME}/dirpcs/MGR.pcm"`
if [ ${pid} = `ps -e |grep ${pid} |grep mgr |cut -d " " -f2` ]
then
#manager process is running on the PID exit success
exit 0
else
if [ ${pid} = `ps -e |grep ${pid} |grep mgr |cut -d " " -f1` ]
then
#manager process is running on the PID exit success
exit 0
else
#manager process is not running on the PID
exit 1
fi
fi
else
#manager is not running because there is no PID file
exit 1
fi
}
#call_ggsci is a generic routine that executes a ggsci command
call_ggsci () {
ggsci_command=$1
ggsci_output=`${OGG_HOME}/ggsci<<EOF
${ggsci_command}
exit
EOF`
}
case $1 in
'start')
#start manager
call_ggsci 'start manager'

#and the process being spawned on the OS. wait before checking

> pullup(oggvip)', STOP_DEPENDENCIES='hard(oggvip)'"
[root@node2 ~]#
