熟悉主要程式的啟停順序瞭解獨佔模式 -excl crsctl start crs與crsctl start cluster 區別

1.熟悉主要程式的啟停順序

1.1 啟動節點rac1：

1 [root@rac1 bin]# ./crsctl start crs -excl

2 CRS-4123: Oracle High Availability Services has been started.  --啟動OHASD程式

25

26 觀察節點rac2：                                                 --節點未啟動，說明 crsctl start crs -excl 只啟動單節點程式

27 [root@rac2 bin]# ps -ef|grep grid         

28 root      5823  4165  0 23:26 pts/1    00:00:00 grep grid

29 [root@rac2 bin]#

1.2 關閉節點rac1

1 [root@rac1 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'

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'

23 CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'rac1' has completed --關閉OHASD程式

24 CRS-4133: Oracle High Availability Services has been stopped.

25 [root@rac1 bin]#

　　總結：重要程式的啟動順序為：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 [root@rac1 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 [root@rac1 bin]#

2.2 RAC1在獨佔模式下時，看看節點RAC2搶佔資源時會發生什麼：

1 [root@rac2 bin]# ./crsctl start crs -excl

2 CRS-4123: Oracle High Availability Services has been started.

3 CRS-2672: Attempting to start 'ora.gipcd' on 'rac2'

4 CRS-2672: Attempting to start 'ora.mdnsd' on 'rac2'

5 CRS-2676: Start of 'ora.gipcd' on 'rac2' succeeded

6 CRS-2676: Start of 'ora.mdnsd' on 'rac2' succeeded

7 CRS-2672: Attempting to start 'ora.gpnpd' on 'rac2'

8 CRS-2676: Start of 'ora.gpnpd' on 'rac2' succeeded

9 CRS-2672: Attempting to start 'ora.cssdmonitor' on 'rac2'

15 CRS-2676: Start of 'ora.diskmon' on 'rac2' succeeded

16 CRS-4402: The CSS daemon was started in exclusive mode but found an active CSS daemon on node rac1, number 1, and is terminating

17 CRS-2674: Start of 'ora.cssd' on 'rac2' failed

18 CRS-2679: Attempting to clean 'ora.cssd' on 'rac2'

19 CRS-2681: Clean of 'ora.cssd' on 'rac2' succeeded

20 CRS-2673: Attempting to stop 'ora.diskmon' on 'rac2'

21 CRS-2677: Stop of 'ora.diskmon' on 'rac2' succeeded

29 CRS-2677: Stop of 'ora.gipcd' on 'rac2' succeeded

30 CRS-4000: Command Start failed, or completed with errors.

31 [root@rac2 bin]#

　　出現狀況了(CRS-4402,CRS-2674),現在看看兩個節點的的程式狀況.

2.3 檢視兩個節點此時的程式狀況

1 節點RAC1的程式狀態：

2 [root@rac1 bin]# ps -ef|grep grid

3 root     16810     1  0 00:56 ?        00:00:01 /u01/grid/bin/ohasd.bin exclusive

4 grid     16944     1  0 00:56 ?        00:00:00 /u01/grid/bin/oraagent.bin

5 grid     16959     1  0 00:56 ?        00:00:00 /u01/grid/bin/gipcd.bin

6 grid     16964     1  0 00:56 ?        00:00:00 /u01/grid/bin/mdnsd.bin

7 grid     16983     1  0 00:56 ?        00:00:00 /u01/grid/bin/gpnpd.bin

8 root     17020     1  0 00:56 ?        00:00:00 /u01/grid/bin/orarootagent.bin

9 grid     17640     1  0 01:02 ?        00:00:00 /u01/grid/bin/diskmon.bin -d -f

10 root     17708 14498  0 01:06 pts/1    00:00:00 grep grid

11 [root@rac1 bin]#

12

13 節點RAC2的程式狀態：

14 [root@rac2 bin]# ps -ef|grep grid

15 root      8557     1  0 01:01 ?        00:00:01 /u01/grid/bin/ohasd.bin exclusive

16 root      8929  7581  0 01:08 pts/1    00:00:00 grep grid

17 [root@rac2 bin]#

　　哈哈，在爭奪資源時RAC1,RAC2兩敗俱傷！獨佔模式一般用於資料庫恢復，升級時。

以非獨佔模式啟動則是去掉 -excl：crsctl start crs

3. crsctl start crs與crsctl start cluster 區別

1 啟動命令：crsctl start  cluster

2 --[root@rac1 bin]# ./crsctl start  cluster

3 CRS-2672: Attempting to start 'ora.cssdmonitor' on 'rac1'

4 CRS-2676: Start of 'ora.cssdmonitor' on 'rac1' succeeded

5 CRS-2672: Attempting to start 'ora.cssd' on 'rac1'

6 CRS-2672: Attempting to start 'ora.diskmon' on 'rac1'

7 CRS-2676: Start of 'ora.diskmon' on 'rac1' succeeded

8 CRS-2676: Start of 'ora.cssd' on 'rac1' succeeded

9 CRS-2672: Attempting to start 'ora.ctssd' on 'rac1'

10 CRS-2676: Start of 'ora.ctssd' on 'rac1' succeeded

11 CRS-2672: Attempting to start 'ora.asm' on 'rac1'

12 CRS-2672: Attempting to start 'ora.evmd' on 'rac1'

13 CRS-2676: Start of 'ora.evmd' on 'rac1' succeeded

14 CRS-2676: Start of 'ora.asm' on 'rac1' succeeded

15 CRS-2672: Attempting to start 'ora.crsd' on 'rac1'

16 CRS-2676: Start of 'ora.crsd' on 'rac1' succeeded

17 [root@rac1 bin]#

　　crsctl start/stop cluster 命令只是控制Start CRS stack(ora.cssdmonitor,ora.cssd,ora.diskmon,ora.ctssd,ora.asm,ora.crsd)。

使用命令 crsctl start/stop cluster 的前提是OHASD程式已經被啟動

結論：crsctl start/stop crs 管理 CRS 包含程式 OHASD ;

　　　crsctl start/stop cluster 不包含OHASD程式,必須要先啟動 OHASD 程式才可以使用
