oracle 11g rac啟停
1.熟悉主要程序的啟停順序
1.1 啟動節點rac1：
1 [[email protected] bin]# ./crsctl start crs -excl 2 CRS-4123: Oracle High Availability Services has been started. --啟動OHASD程序 3 CRS-2672: Attempting to start 'ora.gipcd' on 'rac1' 4 CRS-2672: Attempting to start 'ora.mdnsd' on 'rac1' 5 CRS-2676: Start of 'ora.gipcd' on 'rac1' succeeded --啟動ora.gipcd 6 CRS-2676: Start of 'ora.mdnsd' on 'rac1' succeeded --啟動ora.mdnsd 7 CRS-2672: Attempting to start 'ora.gpnpd' on 'rac1' 8 CRS-2676: Start of 'ora.gpnpd' on 'rac1' succeeded --啟動ora.gpnpd 9 CRS-2672: Attempting to start 'ora.cssdmonitor' on 'rac1' 10 CRS-2676: Start of 'ora.cssdmonitor' on 'rac1' succeeded --啟動ora.cssdmonitor 11 CRS-2672: Attempting to start 'ora.cssd' on 'rac1' 12 CRS-2679: Attempting to clean 'ora.diskmon' on 'rac1' 13 CRS-2681: Clean of 'ora.diskmon' on 'rac1' succeeded --清除ora.diskmon 14 CRS-2672: Attempting to start 'ora.diskmon' on 'rac1' 15 CRS-2676: Start of 'ora.diskmon' on 'rac1' succeeded --啟動ora.diskmon 16 CRS-2676: Start of 'ora.cssd' on 'rac1' succeeded --啟動ora.cssd 17 CRS-2672: Attempting to start 'ora.ctssd' on 'rac1' 18 CRS-2672: Attempting to start 'ora.drivers.acfs' on 'rac1' 19 CRS-2676: Start of 'ora.ctssd' on 'rac1' succeeded --啟動ora.ctssd 20 CRS-2676: Start of 'ora.drivers.acfs' on 'rac1' succeeded --啟動ora.drivers.acfs 21 CRS-2672: Attempting to start 'ora.asm' on 'rac1' 22 CRS-2676: Start of 'ora.asm' on 'rac1' succeeded --啟動ora.asm 23 CRS-2672: Attempting to start 'ora.crsd' on 'rac1' 24 CRS-2676: Start of 'ora.crsd' on 'rac1' succeeded --啟動ora.crsd 25 26 觀察節點rac2： --節點未啟動，說明 crsctl start crs -excl 只啟動單節點程序 27 [[email protected] bin]# ps -ef|grep grid 28 root 5823 4165 0 23:26 pts/1 00:00:00 grep grid 29 [[email protected] bin]#
1.2 關閉節點rac1
1 [[email protected] bin]# ./crsctl stop crs -f 2 CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac1' 3 CRS-2673: Attempting to stop 'ora.crsd' on 'rac1' 4 CRS-2677: Stop of 'ora.crsd' on 'rac1' succeeded --關閉ora.crsd 5 CRS-2673: Attempting to stop 'ora.cssdmonitor' on 'rac1' 6 CRS-2673: Attempting to stop 'ora.ctssd' on 'rac1' 7 CRS-2673: Attempting to stop 'ora.asm' on 'rac1' 8 CRS-2673: Attempting to stop 'ora.drivers.acfs' on 'rac1' 9 CRS-2673: Attempting to stop 'ora.mdnsd' on 'rac1' 10 CRS-2677: Stop of 'ora.cssdmonitor' on 'rac1' succeeded --關閉ora.cssdmonitor 11 CRS-2677: Stop of 'ora.mdnsd' on 'rac1' succeeded --關閉ora.mdnsd 12 CRS-2677: Stop of 'ora.ctssd' on 'rac1' succeeded --關閉ora.ctssd 13 CRS-2677: Stop of 'ora.drivers.acfs' on 'rac1' succeeded --關閉ora.drivers.acfs 14 CRS-2677: Stop of 'ora.asm' on 'rac1' succeeded --關閉ora.asm 15 CRS-2673: Attempting to stop 'ora.cssd' on 'rac1' 16 CRS-2677: Stop of 'ora.cssd' on 'rac1' succeeded --關閉ora.cssd 17 CRS-2673: Attempting to stop 'ora.gpnpd' on 'rac1' 18 CRS-2673: Attempting to stop 'ora.diskmon' on 'rac1' 19 CRS-2677: Stop of 'ora.gpnpd' on 'rac1' succeeded --關閉ora.gpnpd 20 CRS-2673: Attempting to stop 'ora.gipcd' on 'rac1' 21 CRS-2677: Stop of 'ora.diskmon' on 'rac1' succeeded --關閉ora.diskmon 22 CRS-2677: Stop of 'ora.gipcd' on 'rac1' succeeded --關閉ora.gipcd 23 CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'rac1' has completed --關閉OHASD程序 24 CRS-4133: Oracle High Availability Services has been stopped. 25 [[email protected] bin]#
總結：重要程序的啟動順序為：OHASD -> ora.gpnpd -> ora.cssd -> ora.asm -> ora.crsd
2. 瞭解獨佔模式 -excl
既然是以獨佔模式啟動，那麼有些資源一定是不能被其他節點共享的。出現搶佔資源會出現什麼情況
2.1 啟動節點rac1：
1 [[email protected] bin]# ./crsctl start crs -excl -- -excl表示以獨佔模式啟動 2 CRS-4123: Oracle High Availability Services has been started. 3 CRS-2672: Attempting to start 'ora.gipcd' on 'rac1' 4 CRS-2672: Attempting to start 'ora.mdnsd' on 'rac1' 5 CRS-2676: Start of 'ora.gipcd' on 'rac1' succeeded 6 CRS-2676: Start of 'ora.mdnsd' on 'rac1' succeeded 7 CRS-2672: Attempting to start 'ora.gpnpd' on 'rac1' 8 CRS-2676: Start of 'ora.gpnpd' on 'rac1' succeeded 9 CRS-2672: Attempting to start 'ora.cssdmonitor' on 'rac1' 10 CRS-2676: Start of 'ora.cssdmonitor' on 'rac1' succeeded 11 CRS-2672: Attempting to start 'ora.cssd' on 'rac1' 12 CRS-2679: Attempting to clean 'ora.diskmon' on 'rac1' 13 CRS-2681: Clean of 'ora.diskmon' on 'rac1' succeeded 14 CRS-2672: Attempting to start 'ora.diskmon' on 'rac1' 15 CRS-2676: Start of 'ora.diskmon' on 'rac1' succeeded 16 CRS-2676: Start of 'ora.cssd' on 'rac1' succeeded 17 CRS-2672: Attempting to start 'ora.ctssd' on 'rac1' 18 CRS-2672: Attempting to start 'ora.drivers.acfs' on 'rac1' 19 CRS-2676: Start of 'ora.ctssd' on 'rac1' succeeded 20 CRS-2676: Start of 'ora.drivers.acfs' on 'rac1' succeeded 21 CRS-2672: Attempting to start 'ora.asm' on 'rac1' 22 CRS-2676: Start of 'ora.asm' on 'rac1' succeeded 23 CRS-2672: Attempting to start 'ora.crsd' on 'rac1' 24 CRS-2676: Start of 'ora.crsd' on 'rac1' succeeded 25 [[email protected] bin]#
