一.2.1  导读

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黄色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33thread 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racsource)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oggmgrreplicat进程,sourceoggmgrextractextract 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3gsd服务offline属于正常情况!

一.3.2  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

[root@node2 ~]# appvipcfg create -network=1 \

[root@node2 ~]# crsstat | grep oggvip

oggvip                         app.appvip.type            ONLINE     ONLINE     node1

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

[oracle@node1 gg11]$ cat $OGG_HOME/11gr2_ogg_action.scr

#!/bin/sh 

#set the Oracle Goldengate installation directory 

export OGG_HOME=/u01/app/acfsmounts/acfsvol1-232/gg11

 

#set the oracle home to the database to ensure GoldenGate will get the 

#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<

  ${ggsci_command} 

  exit 

  EOF` 

  

case $1 in 

'start') 

  #start manager 

  call_ggsci 'start manager' 

  #there is a small delay between issuing the start manager command 

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

  sleep ${start_delay_secs} 

  #check whether manager is running and exit accordingly 

  check_process 

  ;; 

'stop') 

  #attempt a clean stop for all non-manager processes 

  #call_ggsci 'stop er *' 

  #ensure everything is stopped 

  call_ggsci 'stop er *!' 

  #call_ggsci 'kill er *' 

  #stop manager without (y/n) confirmation 

  call_ggsci 'stop manager!' 

  #exit success 

  exit 0 

  ;; 

'check') 

  check_process 

  ;; 

'clean') 

  #attempt a clean stop for all non-manager processes 

  #call_ggsci 'stop er *' 

  #ensure everything is stopped

一.3.4  使用oracle用户添加oggapp,并授权给oracle用户管理

 

[root@node2 ~]# crsctl add resource oggapp -type cluster_resource \

> -attr "ACTION_SCRIPT=/u01/app/acfsmounts/acfsvol1-232/gg11/11gr2_ogg_action.scr, \

> CHECK_INTERVAL=30, START_DEPENDENCIES='hard(oggvip,ora.asm) \

> pullup(oggvip)', STOP_DEPENDENCIES='hard(oggvip)'"

[root@node2 ~]#

[root@node2 ~]# crsctl status resource oggapp 

NAME=oggapp

TYPE=cluster_resource

TARGET=OFFLINE

STATE=OFFLINE

 

[root@node2 ~]# crsctl setperm resource oggapp -o oracle

[root@node2 ~]#

 

 

 

 

 

一.3.5  检查target端的数据库是否可以正常连接,ogg进程是否运行正常
