节点层相关工具集

1.olsnodes:关注集群由那些节点组成
-n选项：显示每个节点编号
[root@rac1 bin]# pwd
/u01/app/11.2.0/11ggrid/bin
[root@rac1 bin]# ./olsnodes -n
rac1    1
rac2    2
[root@rac1 bin]#
-I选项：显示每个节点的VIP
[root@rac1 bin]# ./olsnodes -i
rac1    rac1vip
rac2    rac2vip
[root@rac1 bin]#
-p选项：显示私有IP地址
[root@rac1 bin]# ./olsnodes -n -l -p
rac1    1       192.168.137.101
-g选项：打开日志开关
[root@rac1 bin]# ./olsnodes -g
rac1
rac2
-V选项：显示详细日志
[root@rac1 bin]# ./olsnodes -v
lang init : Initializing LXL global
main: Initializing CLSS context
memberlist: No of cluster members configured = 256
memberlist: Allocated mem for lease node vector.
memberlist: Leased NodeList entries used = 2.
memberlist: Getting information for nodenum = 1
memberlist: node_name = rac1
memberlist: ctx->lsdata->node_num = 1
print data: Printing the node data
rac1
memberlist: Getting information for nodenum = 2
memberlist: node_name = rac2
memberlist: ctx->lsdata->node_num = 2
print data: Printing the node data
rac2
main: olsnodes executed successfully
term: Terminating LSF
[root@rac1 bin]#
其它参数用法说明
root@rac1 bin]# ./olsnodes -n -p
Usage: olsnodes [ [-n] [-i] [-s] [-t] [ | -l [-p]] | [-c] ] [-g] [-v]
        where
                -n print node number with the node name
                -p print private interconnect address for the local node
                -i print virtual IP address with the node name
                print information for the specified node
                -l print information for the local node
                -s print node status - active or inactive
                -t print node type - pinned or unpinned
                -g turn on logging
                -v Run in debug mode; use at direction of Oracle Support only.
                -c print clusterware name
2.网络层工具oifcfg,网络层由各个节点的网络组件组成，先看下网络配置是什么样的
[root@rac1 bin]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
#public ip:
192.168.44.101 rac1
192.168.44.102 rac2

#private ip:
192.168.137.101 rac1priv
192.168.137.102 rac2priv

#vip
192.168.44.201 rac1vip
192.168.44.202 rac2vip

#scan
192.168.44.200 racscan

#opfiler

192.168.44.251 openfiler
192.168.137.251 openfilerpriv

oifcfg可用来定义和修改oracle集群需要的网卡属性。用法说明
[root@rac1 bin]# pwd
/u01/app/11.2.0/11ggrid/bin
[root@rac1 bin]# ./oifcfg -help

Name:
        oifcfg - Oracle Interface Configuration Tool.

Usage: oifcfg iflist [-p [-n]]
        oifcfg setif {-node | -global} {/:}...
        oifcfg getif [-node | -global] [ -if [/] [-type ] ]
        oifcfg delif [{-node | -global} [[/]]]
        oifcfg [-help]

        - name of the host, as known to a communications network
        - name by which the interface is configured in the system
           - subnet address of the interface
        - type of the interface { cluster_interconnect | public }

[root@rac1 bin]#
用法举例：
iflist显示网口列表
[root@rac1 bin]# ./oifcfg iflist
eth0 192.168.44.0
eth1 192.168.137.0
[root@rac1 bin]#
getif查看每个网卡的属性
[root@rac1 bin]# ./oifcfg getif
eth0 192.168.44.0 global public
eth1 192.168.137.0 global cluster_interconnect
[root@rac1 bin]#
【注】global为接口的配置方式，接口的配置方式分global,node-specific.global则说明所有节点的配置信息相同，即所有节点配置对称。后面当然是不对称。
查看非对称配置
[root@rac1 bin]# ./oifcfg getif -node rac1
[root@rac1 bin]# ./oifcfg getif -node rac2
[root@rac1 bin]#
查看指定类型的网卡配置
[root@rac1 bin]# ./oifcfg getif -type public
eth0 192.168.44.0 global public
[root@rac1 bin]# ./oifcfg getif -type private
eth1 192.168.137.0 global cluster_interconnect
[root@rac1 bin]# ./oifcfg getif -type cluster_interconnect
eth1 192.168.137.0 global cluster_interconnect
[root@rac1 bin]#
搞不清楚，通过setif添加新的网卡，慎用
搞不清楚，通过delif删除接口配置，慎用
3.集群层，负责维护集群内的共享设备，并为上一层的应用集群提供完整的集群状态视图。主要命令包含：crsctl,ocrcheck,ocrdump,ocrconfig

crsctl用来检查CRS进程栈，每个CRS进程的状态，管理VOTEDISK,跟踪CRS进程
用法说明
[root@rac1 bin]# ./crsctl
Usage: crsctl
