-- 添加接口配置

[root@raw1 bin]# ./oifcfg setif -global eth0/192.168.1.119:public

三． 集群层

集群层是指由Clusterware组成的核心集群， 这一层负责维护集群内的共享设备，并为应用集群提供完整的集群状态视图，应用集群依据这个视图进行调整。 这一层共有4个命令： crsctl, ocrcheck,ocrdump,ocrconfig. 后三个是针对OCR 磁盘的。

3.1 CRSCTL

Crsctl 命令可以用来检查CRS 进程栈，每个crs 进程状态，管理Votedisk，跟踪CRS进程功能。

[root@raw1 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 - sets a parameter override

crsctl get css - gets the value of a CSS parameter

crsctl unset css - sets CSS parameter to its default

crsctl query css votedisk - lists the voting disks used by CSS

crsctl add css votedisk - adds a new voting disk

crsctl delete css votedisk - 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 turns on debugging for resources

crsctl query crs softwareversion [] - 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 \

Example: crsctl trace check css

3.1.1 检查CRS 状态

[root@raw1 bin]# ./crsctl check crs

CSS appears healthy

CRS appears healthy

EVM appears healthy

-- 检查单个状态

[root@raw1 bin]# ./crsctl check cssd

CSS appears healthy

[root@raw1 bin]# ./crsctl check crsd
