The JPEG format uses "lossy" compression methods. This means is some minor details of an image saved as a JPEG are lost during compression. The degree of loss can be adjusted via the JPEG.

Quite a lot of the online guides say that you'll have to clone the hard drive image to shrink it, as virtualbox 2.2 and above dropped support for compacting the image. this isn't true, certainly not for version 4.0.4, And you can shrink

Step 2: Clears the remaining space of the guest OS disk, that is, writes the value 0 to every byte of the space not used by the disk. This step is critical, because in the next step, all disk space containing only 0 values will be withdrawn. You can use sdelete, a command line tool produced by sysinternals. Run the following command in the guest OS command line:
Sdelete-c :\

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

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.

In doing experiments, we need to often use VMware this software, after a period of time to find that it generated more and more system files, and sometimes very much disk space. After you delete some unnecessary files and programs in this way, and then find that the system files are not smaller, how do you lose weight?
After the experiment, we found that we need to do the following operations, we can make it thin body.
First, close the snapshot.Because it holds some snapshot data in it, the so-c
