Oracle Clusterware工具2

集群层

　　这一层的管理命令包括crsctl、ocrcheck、ocrdump、ocrconfig，其中后3个命令是针对OCR磁盘的。

CRSCTL:

　　crsctl是一个命令行工具，用于管理Oracle Clusterware daemons（何谓daemon，又名守护进程、后台进程，名称以字母d结尾）。这些daemon包括Cluster Synchronization Services (CSS), Cluster-Ready Services (CRS), and Event Manager (EVM)。

查看crsctl的help：

[oracle@node1 bin]$ ./crsctl

Usage: 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

使用示例：

检查crs状态

[oracle@node1 bin]$ ./crsctl check  crs

CSS appears healthy

CRS appears healthy

EVM appears healthy



检查单个状态 

[oracle@node1 bin]$ ./crsctl check  cssd

CSS appears healthy

[oracle@node1 bin]$ ./crsctl check  crsd

CRS appears healthy

[oracle@node1 bin]$ ./crsctl check  evmd

EVM appears healthy



启动crs栈，必须使用root用户

# ./crsctl start crs

Attempting to start CRS stack 

The CRS stack will be started shortly 



停止crs栈，必须使用root用户：

# ./crsctl stop crs 

Stopping resources. 

Successfully stopped CRS resources 

Stopping CSSD. 

Shutting down CSS daemon. 

Shutdown request successfully issued.



配置crs进程栈是否随着操作系统的启动而自启动，有时出于维护目的需要关闭这个特性，可以用root用户执行下面命令。 

# ./crsctl disable crs 

# ./crsctl enable crs 

这个命令实际是修改了/etc/oracle/scls_scr/node1/root/crsstart这个文件里的内容。



查看votedisk磁盘位置：

[oracle@node1 bin]$ ./crsctl query css votedisk

 0.     0    /dev/raw/raw2



located 1 votedisk(s).

[oracle@node1 bin]$ 

以下两个测试具有一定的破坏力，没有测试 (*^__^*)

--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.

 

--删除votedisk：

--# ./crsctl delete css votedisk /dev/raw/raw4 -force

--successful deletion of votedisk /dev/raw/raw4.

查看crs参数

[oracle@node1 bin]$ ./crsctl get css misscount

60

[oracle@node1 bin]$ 



修改crs参数,必须为root用户

# ./crsctl set css miscount 60

　　CRS由CRS，CSS，EVM三个服务组成，每个服务又是由一系列module组成，crsctl允许对每个module进行跟踪，并把跟踪内容记录到日志中。

查看3个服务各自的模块列表分别如下：

[oracle@node1 bin]$ crsctl lsmodules css

The following are the CSS modules :: 

    CSSD

    COMMCRS

    COMMNS

[oracle@node1 bin]$ crsctl lsmodules evm

The following are the EVM modules :: 

   EVMD

   EVMDMAIN

   EVMCOMM

   EVMEVT

   EVMAPP

   EVMAGENT

   CRSOCR

   CLUCLS

   CSSCLNT

   COMMCRS

   COMMNS

[oracle@node1 bin]$ crsctl lsmodules crs

The following are the CRS modules :: 

    CRSUI

    CRSCOMM

    CRSRTI

    CRSMAIN

    CRSPLACE

    CRSAPP

    CRSRES

    CRSCOMM

    CRSOCR

    CRSTIMER

    CRSEVT

    CRSD

    CLUCLS

    CSSCLNT

    COMMCRS

    COMMNS

[oracle@node1 bin]$ 

跟踪CSSD模块，需要root用户执行： 

# ./crsctl debug log css "CSSD:1"

Configuration parameter trace is now set to 1.

Set CRSD Debug Module: CSSD  Level: 1

查看跟踪日志:
