systems on a single entity server. This allows each system service to run on a single operating system, while multiple operating systems can run concurrently on the same entity server.Not only maintain the service isolation, but also improve the efficiency of hardware resources. This is: Server consolidation (Consolidation).3) High availability.You can solve complex problems such as high availability, fault tolerance, load balancing, and backup.Can solve the problem that the device cannot solve

Some friends want to use the VirtualBox tool to build a RAC test environment and share the storage division on their personal computers, but they do not know how to use the RAC test environment, the following section describes how to use VirtualBox to build a RAC test environment and share the storage design process. The process is as follows: 1. Use the vboxmanage.exe tool in virtualboxto create a disk. This tool can be found in the VirtualBox installation directory. # VBoxManage.exe createh

. Select the template and click Next. Select storage. By default, only one storage is available. Select the number of virtual desktops to be created on the xen Server 2 and the virtual desktop computing group. The names of the virtual desktops created subsequently are vdgroup1 and vdgroup2. Select the ou in the ad, and you can specify the xendesktop ou by default. Click the group name of the virtual desktop on the DDC Server In

There are still many steps to generate a shared disk and mount it to asm when Oracle VM builds Oracle RAC. Record it. The premise is that a linux has been installed in the VM.1. here I create five disks, cd C: \ Program Files \ Oracle \ VirtualBoxVBoxManage.exe createhd-filename D: \ OracleVM \ ASM \ asm1.vdi-size 5120-format VDI-variant FixedVBoxManage.exe createhd-filename D: \ OracleVM \ ASM \ asm2.

This article describes how to build a Acfs file system on a virtual machine that already has 12c RAC installed, and use the ACFS snapshot to brush a cow (Copy-On-Write) library to do the test library. Highlight Step: Add ASM disk to virtual machine to build Acfs file systemSecond, create Acfs file systemThird, create the database on the Acfs file system in Node 1. (12c supports data files, control files, log files and other database files on the ACFS.) Reference doc ID 1369107.1 acfs Advanced

OracleLinux configure UDEVSCSIRules Udev scsi Rules configuration in Oracle Linux The configuration of ASM in Oracle RAC can be implemented in two ways: raw and asmlib. Raw is recommended for actual maintenance. There are two ways to use raw: multipath and UDEV. On the RedHat platform, refer: Redhat 5.4 + ASM + RAW + Oracle 10g RAC installation documentation For ASMLIB, refer: RAW + asm rac installation document In this article, let's take a look at the UDEV configuration in Oracle Linux.

VirtualBox Virtual disk space is not enough, the default is 10G. To enlarge, the graphical interface does not find the operable menu. Google a bit with the VBox command tool vboxmanage can be resolved.

Adjust and expand the disk space of VirtualBox in VMDK format If the format of the virtual machine is VDI, you can use this article to adjust the disk size: adjust the size of the VirtualBox hard disk. However, when creating a virtual machine, the landlord used the VMDK format to ensure compatibility with VMWare. At this time, it will be a bit difficult to expand the hard disk space. An error will be reported when you follow the procedure described ab

Virtralbox uses a VDI file to provide a virtual hard disk for the Virtual Machine. during use, this file grows more than actually used, for example, in a Virtual Machine, the operating system may have only 2 GB space for other files, but the virtual hard disk file may have 5 GB space in the host machine, and the most important thing is that even if the file is deleted from the virtual machine, it will not be reflected in the

I made a WinXP virtual image with VirtualBox.You want to make a few copies without reinstalling, that is, loading several virtual machines at the same time.However, directly copying the installed VDI files, the system will report the error that the UUID already exists.Therefore, you need to modify the UUID to use$CP Winxp1.vdi (source VDI) Winxp2.
