ORACLE 11G RAC--CLUSTERWARE工具集1

目的：熟悉工具集的使用

節點層相關工具集

1.olsnodes:關注叢集由那些節點組成
-n選項：顯示每個節點編號
[root@rac1 bin]# pwd
/u01/app/11.2.0/11ggrid/bin
[root@rac1 bin]# ./olsnodes -n
rac1    1
rac2    2
[root@rac1 bin]#
-I選項：顯示每個節點的VIP
[root@rac1 bin]# ./olsnodes -i
rac1    rac1vip
rac2    rac2vip
[root@rac1 bin]#
-p選項：顯示私有IP地址
[root@rac1 bin]# ./olsnodes -n -l -p
rac1    1       192.168.137.101
-g選項：開啟日誌開關
[root@rac1 bin]# ./olsnodes -g
rac1
rac2
-V選項：顯示詳細日誌
[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]#
其它引數用法說明
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.網路層工具oifcfg,網路層由各個節點的網路元件組成，先看下網路配置是什麼樣的
[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可用來定義和修改oracle叢集需要的網路卡屬性。用法說明
[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]#
用法舉例：
iflist顯示網口列表
[root@rac1 bin]# ./oifcfg iflist
eth0  192.168.44.0
eth1  192.168.137.0
[root@rac1 bin]#
getif檢視每個網路卡的屬性
[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為介面的配置方式，介面的配置方式分global,node-specific.global則說明所有節點的配置資訊相同，即所有節點配置對稱。後面當然是不對稱。
檢視非對稱配置
[root@rac1 bin]# ./oifcfg getif -node rac1
[root@rac1 bin]# ./oifcfg getif -node rac2
[root@rac1 bin]#
檢視指定型別的網路卡配置
[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，通過setif新增新的網路卡，慎用
搞不清楚，通過delif刪除介面配置，慎用
3.叢集層，負責維護叢集內的共享裝置，併為上一層的應用叢集提供完整的叢集狀態檢視。主要命令包含：crsctl,ocrcheck,ocrdump,ocrconfig

crsctl用來檢查CRS程式棧，每個CRS程式的狀態，管理VOTEDISK,跟蹤CRS程式
用法說明
[root@rac1 bin]# ./crsctl
Usage: crsctl
