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

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

Since last year, Citrix products have basically been adhering to the last day of each quarter, a large-scale update of the Xenapp/xendesktop 7.6 version of the habit, September 30 This day no accident, released Feature Pack 3.An important part of this update is full support for Windows 10. As Microsoft released Windows 10 on July 29, manufacturers began supporting Windows 10 with support for Windows 10 through the TP version of the VDA earlier. Citrix now begins full and formal support for Windo

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.

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.

Solve a basic problem first: How to make less code?Technical Means Technical means are not the focus of our speech today. Because technical means are limited by the level of developers, it is extremely difficult to increase the number of technical means at once. Moreover, the business itself will limit the use of technical means. However, let's

paying close attention to the development of flash drives recently ." 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
