數(shù)據(jù)庫關閉ok后此時我們進行關閉crs服務，切忌不要直接關閉ASM實例，在11g中 11.2.0.2 中 ocr 服務的信息存放在asm 磁盤上，是依賴于asm的，所以要關閉crs 而不是直接關閉asm實例，若在此處強行關閉asm實例，很有可能造成的后果是asm磁盤損壞或者丟失，導致整個集群徹底崩潰。我在測試RAC時，曾dismount某個磁盤組后，首先關閉了數(shù)據(jù)庫，接著直接關閉了asm實例，關閉時一切正常。無報錯，但當啟動時，發(fā)現(xiàn)asm無法啟動crs提示CRS-0184: Cannot communicate with the CRS daemon.無論如何也是無法啟動CRS的，意識到可能是表決磁盤或者OCR出現(xiàn)問題，隨即查看asm磁盤情況：oracleasm listdisks，沒有任何磁盤信息，oracleasm scandisks也是同樣的情況，這下估計麻煩了。在登錄到另外一個節(jié)點上，同樣命令查看asm磁盤，發(fā)現(xiàn)磁盤正常。故此此時我也將該節(jié)點的數(shù)據(jù)庫及asm實例關閉，然后重啟服務器，之后悲劇的一幕想當然的發(fā)生了，兩個節(jié)點都無法掃描到asm磁盤信息。整個集群破壞的很徹底，丟失數(shù)據(jù)。也許是我個人原因造成這種異常的數(shù)據(jù)丟失，但個人還是建議按照常規(guī)的順序來關閉啟動RAC。

2.          [root@RAC01 bin]# ./crsctl stop crs

如果你足夠細心，你可以通過下面的關閉日志看出在RAC的CRS關閉的過程中是一個怎樣的順序以及關閉crs的時候都會有那些服務會同時關閉。此外你可能還會發(fā)現(xiàn)我們的這個命令是在RAC01這個節(jié)點執(zhí)行的，所以這時候應該RAC02這個節(jié)點還是可以正常使用的。強烈建議大家對下面的日志進行研究。

4.          啟動crs服務：

[root@RAC01 bin]# ./crsctl start crs-------------此處可能需要等待一段時間。

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

6.          啟動數(shù)據(jù)庫：

[grid@RAC02 ~]$ srvctl start database -d RACwh

PRCR-1079 : Failed to start resource ora.racwh.db

ORA-16038: log 3 sequence# 41 cannot be archived

ORA-19504: failed to create file ""

ORA-00312: online log 3 thread 2: '+DATA/racwh/redo03.log'

CRS-2674: Start of 'ora.racwh.db' on 'rac01' failed

CRS-2632: There are no more servers to try to place resource 'ora.racwh.db' on that would satisfy its placement policy

[grid@RAC02 ~]$

        針對上述的報錯，經(jīng)查看原來是歸檔日志所在的asm未能mount所致，執(zhí)行該磁盤的mount后重新執(zhí)行數(shù)據(jù)庫啟動即可。

此外給大家推薦幾個日常的啟動關閉命令：

其他管理維護指南

一.通過srvctl管理

1.關閉RAC數(shù)據(jù)庫服務順序

[oracle@dbp ~] $ srvctl stop   database    -d RACwh

[oracle@dbp ~] $ srvctl stop   asm         -n RAC01

[oracle@dbp ~] $ srvctl stop   asm         -n RAC02

[oracle@dbp ~] $ srvctl stop   nodeapps    -n RAC01

[oracle@dbp ~] $ srvctl stop   nodeapps    -n RAC02

2.啟動RAC數(shù)據(jù)庫服務順序

[oracle@RAC01 ~] $ srvctl start  nodeapps    -n RAC01

[oracle@RAC01 ~] $ srvctl start  nodeapps    -n RAC02

[oracle@RAC01 ~] $ srvctl start  asm         -n RAC01

[oracle@RAC01 ~] $ srvctl start  asm         -n RAC02

[oracle@RAC01 ~] $ srvctl start  database    -d RACwh

3.其他命令

實例管理

[oracle@RAC01 ~] $ srvctl status instance    -d RACwh  -i RACwh2

[oracle@RAC01 ~] $ srvctl stop   instance    -d RACwh  -i RACwh2

[oracle@RAC01 ~] $ srvctl start  instance    -d RACwh  -i RACwh2

監(jiān)聽管理

[oracle@RAC01 ~] $ srvctl status listener    -n RAC01

[oracle@RAC01 ~] $ srvctl stop   listener    -n RAC01

[oracle@RAC01 ~] $ srvctl start  listener    -n RAC01

二.通過crsctl工具管理

[oracle@RAC01 ~] $ crs_stat -t

[oracle@RAC01 ~] $ crs_stat

[oracle@RAC01 ~] $ crs_start -all

[oracle@RAC01 ~] $ crs_stop -all

[oracle@RAC01 ~] $ crs_stop "ora. RACwh.db"

Crs_stat命令在oracle11g后逐漸趨于廢棄，如下即可明白：

[grid@RAC02 ~]$ crs_stat -h

This command is deprecated and has been replaced by 'crsctl status resource'

This command remains for backward compatibility only

Usage:  crs_stat [resource_name [...]] [-v] [-l] [-q] [-c cluster_member]

        crs_stat [resource_name [...]] -t [-v] [-q] [-c cluster_member]

        crs_stat -p [resource_name [...]] [-q]

        crs_stat [-a] application -g

        crs_stat [-a] application -r [-c cluster_member]

        crs_stat -f [resource_name [...]] [-q] [-c cluster_member]

        crs_stat -ls [resource_name [...]] [-q]
