1.在rac2節(jié)點(diǎn)使用oracleasm找不到共享磁盤(pán)

成都創(chuàng)新互聯(lián)公司專(zhuān)注于觀山湖企業(yè)網(wǎng)站建設(shè),成都響應(yīng)式網(wǎng)站建設(shè)公司,商城開(kāi)發(fā)。觀山湖網(wǎng)站建設(shè)公司,為觀山湖等地區(qū)提供建站服務(wù)。全流程定制網(wǎng)站制作，專(zhuān)業(yè)設(shè)計(jì)，全程項(xiàng)目跟蹤，成都創(chuàng)新互聯(lián)公司專(zhuān)業(yè)和態(tài)度為您提供的服務(wù)

[root@rac2 ~]# oracleasm scandisks
Reloading disk partitions: done
Cleaning any stale ASM disks...
Scanning system for ASM disks...
[root@rac2 ~]#

解決方法:

  是因?yàn)樵趓ac1節(jié)點(diǎn)格式化磁盤(pán)沒(méi)有使用partprobe命令,分區(qū)沒(méi)有生效

在rac1執(zhí)行:

[root@rac1 ~]# partprobe

在rac2執(zhí)行:

[root@rac2 ~]# /usr/sbin/oracleasm scandisks
Reloading disk partitions: done
Cleaning any stale ASM disks...
Scanning system for ASM disks...

2.安裝grid集群軟件時(shí)出現(xiàn)ORACLE_HOME和ORACLE_BASE目錄不對(duì)

錯(cuò)誤提示:

INS-32026]The Software Location specified should not be under Oracle base location.
  CAUSE: Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location. As a result, all named directories in the software location path will acquire root ownership. This may create problems for subsequent installations into the same Oracle base.
  ACTION: Specify software location outside of Oracle base

解決方法:

我當(dāng)前目錄是:ORACLE_BASE=/home/grid

      ORACLE_HOME=/home/grid/11.2.0/grid

這樣目錄是不正確的,因?yàn)镺RACLE_BASE和ORACLE_HOME目錄要分開(kāi),ORACLE_BASE安裝好后是有root權(quán)限的,而ORACLE_HOME則沒(méi)有.

這樣才對(duì):ORACLE_BASE=/home/grid/app

     ORACLE_HOME=/home/grid/11.2.0/grid

3.在安裝grid到最后一步出錯(cuò)誤,是因?yàn)閟can的IP問(wèn)題補(bǔ)占用了

日志:

INFO: All nodes have same "hosts" entry defined in file "/etc/nsswitch.conf"

INFO: Check for integrity of name service switch configuration file "/etc/nsswitch.conf" passed

INFO: ERROR:

INFO: PRVG-1101 : SCAN name "scan-cluster" failed to resolve

INFO: ERROR:

INFO: PRVF-4657 : Name resolution setup check for "scan-cluster" (IP address: 192.168.3.155) failed

INFO: ERROR:

INFO: Verification of SCAN VIP and Listener setup failed

INFO: Checking OLR integrity...

INFO: Checking OLR config file...

INFO: OLR config file check successful

INFO: Checking OLR file attributes...

INFO: OLR file check successful

解決方法:

(1).直接跳過(guò)不影響

(2),修改系統(tǒng)的nslookup二進(jìn)制文件(http://www.ithao123.cn/content-1094742.html)

4.crs無(wú)法共享磁盤(pán)通信

錯(cuò)誤信息:

CRS-0184: Cannot communicate with the CRS daemon.

日志信息:

解決方法:

 這是共享磁盤(pán)的問(wèn)題,我是用iscsi做的共享,查看了下asm只能掛載自己在磁盤(pán)組,將共享磁盤(pán)換成虛擬機(jī)自帶的磁盤(pán)共享就解決了.
