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
Disk
Use the virtualbox command to create the image. Shut down the VM before creating the VM.

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
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.

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.

viruses and network impacts. The editor was often harassed by viruses and delays in the POC and implementation of the project. Most security problems can be solved by installing patches. In addition, if your computer has already installed IIS, uninstall it before installing Connection Server.

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.

Attention
It is recommended that the operating system, including domain control, first install the latest patches to prevent the system from viruses and network impact. The editor has often been subjected to virus disturbances during project POC and implementation, and delays, and most security issues can be solved by installing patches. Also, if you have IIS installed on your computer, uninstall before installing Connection server.

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
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

Disk I/O performance is very important for storage arrays, But I/O problems may also come from the network. For example, an Ethernet-based SAN, such as iSCSI or FCoE, may cause network bandwidth bottlenecks. Therefore, configuring storage on an independent application server can simplify potential network congestion problems. Network I/O performance can also respond to the bandwidth-intensive application stream. The bottlenec
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.
Prepare a template computer
Prepare a Windows XP or Windows 7 virtual machine, install the operating system, update the latest patch, and install the application software to configure the user environment. After everything is ready, make sure that your computer has Installed VMware Tools and started preparing the View's template computer. Now the model machine does not need to be added to the domain.
