重灌系統後快速還原RAC-APP

1、快速恢復RAC節點系列文章：

Votedisk的恢復：http://www.itpub.net/thread-1876017-1-1.html
快速還原RAC節點程式：http://www.itpub.net/thread-1878271-1-1.html
2、測試環境：10.2.0.1.0  on rhel5
3、測試過程如下，歡迎補充、指正


一、建立rac node上需要備份的程式檔案清單
# find  /etc/init.d/init.*                       >lst
find  /etc/rc{0,1,2,4,6}.d/K96init.crs         >>lst
find  /etc/rc{3,5}.d/S96init.crs               >>lst
find  /etc/inittab.crs /etc/inittab            >>lst
find  /home/oracle/oraInventory                >>lst
find  /home/oracle/.ssh                        >>lst
#find  /u01                                     >>lst   #為節約測試時間暫時註釋掉
find  /etc/oraInst.loc /etc/oracle /etc/oratab >>lst
find   /opt/oracle                             >>lst
find   /opt/ORCLfmap                           >>lst
find   /usr/local/bin/coraenv                  >>lst
find   /usr/local/bin/dbhome                   >>lst
find   /usr/local/bin/oraenv                   >>lst

二、將清單中的檔案打包備份
#  tar -czvPWf $HOSTNAME.tgz -T lst

補充說明：
tar  -c,--create：建立一個新歸檔
tar  -z, --gzip, --gunzip：使用 gzip 處理歸檔
tar  -v, --verbose：詳細地列出處理的檔案
tar  -P, --absolute-names：不要從檔名中清除引導符‘/’
tar  -W, --verify：在寫入以後嘗試校驗歸檔
tar  -f,--file:指定備份檔案。後緊跟被處理的檔名，不要再加其它引數
tar  -T：從檔名清單建立tar歸檔

三、模擬重灌系統（本測試僅將RAC程式刪除）
# rm -rf /etc/init.d/init.*
rm -f /etc/rc{0,1,2,4,6}.d/K96init.crs
rm -f /etc/rc{3,5}.d/S96init.crs
rm -f /etc/inittab.crs
echo y|cp /etc/inittab.orig /etc/inittab
rm -rf /home/oracle/oraInventory
rm -rf /home/oracle/.ssh
#rm -rf /u01                            #為節約測試時間暫時不刪掉/u01
rm -rf /etc/oraInst.loc
rm -rf /etc/oracle
rm -rf /etc/oratab
rm -rf /opt/oracle
rm -rf /opt/ORCLfmap
rm -rf /tmp/hsperfdata_oracle
rm -rf /tmp/OraInstall*
rm -rf /tmp/OraInstall*
rm -rf /usr/local/bin/coraenv
rm -rf /usr/local/bin/dbhome
rm -rf /usr/local/bin/oraenv
#mkdir -p /u01/app/oracle
#chown -R oracle:oinstall /u01
#chmod -R 775 /u01

reboot

四、從 $HOSTNAME.tgz備份恢復中恢復程式檔案
# ls *.tgz 
rac1.tgz
# echo $HOSTNAME
rac1
# echo y|tar -xzwPf $HOSTNAME.tgz

補充說明：
tar  -w, --interactive, --confirmation 每次操作都要求確認
tar  -P, --absolute-names：不要從檔名中清除引導符‘/’

五、驗證還原是否有效果
1、以root身份重啟RAC節點
[root@rac1 ~]# reboot
2、驗證程式是否已經執行
[oracle@rac1 ~]$ crs_stat -t
Name           Type           Target    State     Host        
------------------------------------------------------------

六、特別補充
# cat 60-raw.rules 
# This file and interface are deprecated.
# Applications needing raw device access should open regular
# block devices with O_DIRECT.
#
# Enter raw device bindings here.
#
# An example would be:
#   ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
#   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8, minor 1.
ACTION=="add", KERNEL=="/dev/sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="17",RUN+="/bin/raw /dev/raw/raw1 %M %m"
ACTION=="add", KERNEL=="/dev/sdc1",RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="33",RUN+="/bin/raw /dev/raw/raw2 %M %m"
ACTION=="add", KERNEL=="/dev/sdd1",RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="49",RUN+="/bin/raw /dev/raw/raw3 %M %m"
ACTION=="add", KERNEL=="/dev/sde1",RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="65",RUN+="/bin/raw /dev/raw/raw4 %M %m"
KERNEL=="raw[1-4]", OWNER="oracle", GROUP="oinstall", MODE="640"
