centos6中搭建oracle 11g rac及常用维护命令 - 图文

vmware-vdiskmanager.exe -c -s 5g -a lsilogic -t 2 \

Vmware-vdiskmanager.exe -c -s 5g -a lsilogic -t 2 \

vmware-vdiskmanager.exe -c -s 5g -a lsilogic -t 2 \

4.2 将共享磁盘挂到两台虚拟机

关闭两台虚拟机并退出VM，分别用记事本打开虚拟机安装位置中虚拟机名字. vmx， 例如我的2个虚拟机安装在G:\\rac1 和G:\\rac2 打开G:\\rac1，找到rac1.vmx

添加以下内容

disk.EnableUUID=\disk.locking = \scsi1.shared = \

diskLib.dataCacheMaxSize = \

diskLib.dataCacheMaxReadAheadSize = \diskLib.dataCacheMinReadAheadSize = \diskLib.dataCachePageSize= \diskLib.maxUnsyncedWrites = \

scsi1.present = \scsi1.virtualDev = \scsil.sharedBus = \scsi1:0.present = \

scsi1:0.mode = \scsi1:0.fileName = \F:\\shdisk\\vot.vmdk\scsi1:0.deviceType = \scsi1:0.redo = \

13

scsi1:1.present = \

scsi1:1.mode = \scsi1:1.fileName = \F:\\shdisk\\fra.vmdk\scsi1:1.deviceType = \scsi1:1.redo = \scsi1:2.present = \

scsi1:2.mode = \scsi1:2.fileName = \F:\\shdisk\\data.vmdk\scsi1:2.deviceType = \scsi1:2.redo = \

4.3 两个虚拟机开机，格式化硬盘，确认是否共享成功。

在rac1上执行fdisk格式化刚才添加的硬盘，从rac2执行fdsik -l ，确认看以正常看到统一的分区 在rac1 上对第一块硬盘分区

[root@rac1 pnweb]# fdisk /dev/sdb
