oracle bare metal

The first part is to play PCDUINO3 under the bare metal, this process allows us to better understand the embedded system, familiar with the platform we use. First introduce the following development environment: Virtual machine: Vmware®workstation 10.0.2 build-1744117 System: Linux Slackware 3.2.29-SMP #2 SMP Cross compiler: arm-linux-gnueabihf-version number: GCC version 4.8.2 20130805 (prerelease) (Crosst

Nonsense will not say, straight into the subject. Before the research ARM11 development, using the OK6410, online bought the Flying Ling, to tell the truth, the software is really bad, the beginner will really be killed. Take a bare-metal development environment, for half a day, fortunately. 1. Material: An SD card, a big one, Kingston or SanDisk can. A serial line, no serial computer, the tragedy, you h

Therefore, the bare device is used for database applications with frequent reads and writes, it can greatly improve the performance of the database system. Of course, this is true when the disk I/O is very large and the disk I/O is already known as a system bottleneck. If the disk read/write operation is so f

It is the responsibility of the application to read and write it. Does not pass the file system buffer. 2. How to ident

Of course, this is only true if disk I/O is very large and disk I/O is already known as a system bottleneck. If the disk reads and writes are very frequent, so that disk reads and writes become the system bottleneck, then the use of

A bare device, also called a bare partition (raw partition), is a special character device that is not formatted and is not read by UNIX through a file system. This article collects the bare devices and Oracle Quiz 20 cases. 1. What is called the naked device? A bare devic

Recently, I found that there are more or less many problems in the online articles on creating a library with bare devices bound to linux lv, which is easy to mislead beginners. Therefore, I sorted out the preliminary steps for directly creating a library on a bare disk. OS: RedHat 4.4First, add a hard disk to the vmvm and enter the system to create a partition. We use sdc1 to divide the lv[Root @

Recently I plan to study the Linux bare device, so I tested it in linux to create an Oracle 10g Database Based on the bare device. Follow these steps: I.

In Linux, a raw device is used to create an oracle tablespace. Today, a test is performed to create a tablespace in linux: 1. create logical volume: run # lvcreate-L 100 M-n vg30 vg02. bind the logical volume to the bare device as the root user: under the root user, # raw/dev/raw/raw1/dev/vg01/oradta_life3. grant the read and write permissions of bare devices to

You need to know the fact that disk I/O is an important reason to affect Oracle database performance. In essence, any Oracle database is responsible for storing data, and querying data from disk is a very expensive and time-consuming operation. Because many Oracle systems require a large amount of I/O operations, many Oracle
