Oracle Clusterware工具2

叢集層

　　這一層的管理命令包括crsctl、ocrcheck、ocrdump、ocrconfig，其中後3個命令是針對OCR磁碟的。

CRSCTL:

　　crsctl是一個命令列工具，用於管理Oracle Clusterware daemons（何謂daemon，又名守護進程、後台進程，名稱以字母d結尾）。這些daemon包括Cluster Synchronization Services (CSS), Cluster-Ready Services (CRS), and Event Manager (EVM)。

查看crsctl的help：

[oracle@node1 bin]$ ./crsctlUsage: crsctl check  crs          - checks the viability of the CRS stack       crsctl check  cssd         - checks the viability of CSS       crsctl check  crsd         - checks the viability of CRS       crsctl check  evmd         - checks the viability of EVM       crsctl set    css <parameter> <value> - sets a parameter override       crsctl get    css <parameter> - gets the value of a CSS parameter       crsctl unset  css <parameter> - sets CSS parameter to its default       crsctl query  css votedisk    - lists the voting disks used by CSS       crsctl add    css votedisk <path> - adds a new voting disk       crsctl delete css votedisk <path> - removes a voting disk       crsctl enable  crs    - enables startup for all CRS daemons       crsctl disable crs    - disables startup for all CRS daemons       crsctl start crs  - starts all CRS daemons.       crsctl stop  crs  - stops all CRS daemons. Stops CRS resources in case of cluster.       crsctl start resources  - starts CRS resources.        crsctl stop resources  - stops  CRS resources.        crsctl debug statedump evm  - dumps state info for evm objects       crsctl debug statedump crs  - dumps state info for crs objects       crsctl debug statedump css  - dumps state info for css objects       crsctl debug log css [module:level]{,module:level} ...                              - Turns on debugging for CSS        crsctl debug trace css - dumps CSS in-memory tracing cache       crsctl debug log crs [module:level]{,module:level} ...                              - Turns on debugging for CRS        crsctl debug trace crs - dumps CRS in-memory tracing cache       crsctl debug log evm [module:level]{,module:level} ...                              - Turns on debugging for EVM       crsctl debug trace evm - dumps EVM in-memory tracing cache       crsctl debug log res <resname:level> turns on debugging for resources       crsctl query crs softwareversion [<nodename>] - lists the version of CRS software installed       crsctl query crs activeversion - lists the CRS software operating version       crsctl lsmodules css - lists the CSS modules that can be used for debugging       crsctl lsmodules crs - lists the CRS modules that can be used for debugging       crsctl lsmodules evm - lists the EVM modules that can be used for debugging If necesary any of these commands can be run with additional tracing by adding a "trace" argument at the very front. Example: crsctl trace check css

使用樣本：

檢查crs狀態[oracle@node1 bin]$ ./crsctl check  crsCSS appears healthyCRS appears healthyEVM appears healthy檢查單個狀態 [oracle@node1 bin]$ ./crsctl check  cssdCSS appears healthy[oracle@node1 bin]$ ./crsctl check  crsdCRS appears healthy[oracle@node1 bin]$ ./crsctl check  evmdEVM appears healthy啟動crs棧，必須使用root使用者# ./crsctl start crsAttempting to start CRS stack The CRS stack will be started shortly 停止crs棧，必須使用root使用者：# ./crsctl stop crs Stopping resources. Successfully stopped CRS resources Stopping CSSD. Shutting down CSS daemon. Shutdown request successfully issued.配置crs進程棧是否隨著作業系統的啟動而自啟動，有時出於維護目的需要關閉這個特性，可以用root使用者執行下面命令。 # ./crsctl disable crs # ./crsctl enable crs 這個命令實際是修改了/etc/oracle/scls_scr/node1/root/crsstart這個檔案裡的內容。查看votedisk磁碟位置：[oracle@node1 bin]$ ./crsctl query css votedisk 0.     0    /dev/raw/raw2located 1 votedisk(s).[oracle@node1 bin]$ 

以下兩個測試具有一定的破壞力，沒有測試 (*^__^*)

--增加votedisk：--# ./crsctl add css votedisk /dev/raw/raw3 -force--Now formatting voting disk: /dev/raw/raw3--successful addition of votedisk /dev/raw/raw3. --刪除votedisk：--# ./crsctl delete css votedisk /dev/raw/raw4 -force--successful deletion of votedisk /dev/raw/raw4.

查看crs參數[oracle@node1 bin]$ ./crsctl get css misscount60[oracle@node1 bin]$ 修改crs參數,必須為root使用者# ./crsctl set css miscount 60

　　CRS由CRS，CSS，EVM三個服務組成，每個服務又是由一系列module組成，crsctl允許對每個module進行跟蹤，並把跟蹤內容記錄到日誌中。

查看3個服務各自的模組列表分別如下：

[oracle@node1 bin]$ crsctl lsmodules cssThe following are the CSS modules ::     CSSD    COMMCRS    COMMNS[oracle@node1 bin]$ crsctl lsmodules evmThe following are the EVM modules ::    EVMD   EVMDMAIN   EVMCOMM   EVMEVT   EVMAPP   EVMAGENT   CRSOCR   CLUCLS   CSSCLNT   COMMCRS   COMMNS[oracle@node1 bin]$ crsctl lsmodules crsThe following are the CRS modules ::     CRSUI    CRSCOMM    CRSRTI    CRSMAIN    CRSPLACE    CRSAPP    CRSRES    CRSCOMM    CRSOCR    CRSTIMER    CRSEVT    CRSD    CLUCLS    CSSCLNT    COMMCRS    COMMNS[oracle@node1 bin]$ 

跟蹤CSSD模組，需要root使用者執行： 

# ./crsctl debug log css "CSSD:1"Configuration parameter trace is now set to 1.Set CRSD Debug Module: CSSD  Level: 1
