Mysql connects to the database, mysql connects to the database Wow, there's something that comes in touch with the background today! Isn't "mysql" counted? Hey, I feel very happy to write code. Let's summarize it today! (Good god, don't like it, don't spray it) 1. Start mysql and link the data! Yes, right? Mysql-uroot-p // connect data Net start mysql // start mysql 2. query the data on the current server.

Here we will talk about how Flash (as3) connects to the database through Asp.net, hoping to help some children's shoes. Let's talk about the logic first, and then paste itCode: As3 cannot directly operate databases. It can only operate data in one background language, such as C # And java. Here we will talk about as3's simple logic of calling Asp.net to operate databases, that is, as3 initiates a request, uses Asp.net to accept the correspondin

After 11.2, you can rename ASM DiskGroup without having to create a new diskgroup, and then do image copy. In 11.2, in the GI home, with a command renamedg, look at the following example: RENAMEDG phase=The steps can be divided into 2 phase, the first is to generate a configure file (Renamedg_config), and the second phase is to execute the Configure file, and the Phase=both in the document is to indicate that the build is executed directly after it

I. Features of ASM1. automatically adjust the I/O LoadASM can automatically adjust the I/O load in all available disks, which not only avoids manual I/O adjustment, but also optimizes the performance, with ASM, you can increase the database size online without shutting down the database.2. Band-based storageASM divides files into multiple allocation units (allocation units) for storage, and allocates the AU of each file among all disks.3. Online Autom

The ASM instance is similar to a common database instance (RDBMS) and also consists of SGA and a bunch of background processes.

ASM (AutomaticStorageManagement) is a software storage solution officially recommended by Oracle. Since the 10g version was officially launched, the position of ASM in the software architecture is constantly improving. The first step is to strip ASM from the database layer at 11 GB and manage it in GridInfrastructure. ASMDisk becomes the basic component of ACFS (

ASM concepts 1. what is Automatic Storage Management (ASM, it is a disk management tool that can implement strip, image data files, recovery files, and other files among multiple physical devices. The distribution unit is AUs (allocation units) the balance is distributed across all disks in the disk group. ASM uses the index technology to track the positions of e

The purpose of this document is to provide information about the ASM rolling upgrade feature and step by step to install a patchset or patch in ASM home without downtime.Solution The following conditions shoshould be met for to perform ASM rolling upgrade (*) An ASM rolling upgrade applies only to clustered

Label:ASM OverviewAutomatic Storage Management (ASM) is a great new feature in Oracle database 10g that provides services such as file systems, logical volume managers, and software raid in a platform-agnostic manner. ASM can stripe and mirror disks, enabling the addition or removal of disks as the database is loaded, and automatic balancing of I/O to remove "hotspots".Files in

In the previous article wrote the file system library, in the exception recovery before the backup method (Oracle exception recovery before the backup protection site recommended-filesystem environment), for the ASM Library, because the ASM inside the data file can not direct DD file header, As a result, the backup approach has changed. For ASM is mount, but the

1. concepts related to ASM (concept taken from: the world of amasha) 1. What is ASM (Auto Storage Management) 1 Automatic Storage Management is a tool used to manage disks.2 Supports striping, mirror data files, and restore files between multiple physical devices.3 Files are evenly distributed across all disks in the disk group according to the allocation unit aus (Allocation units).

I. basic information and concepts 1. ASM is an ORACLE automatic storage management software. It uses bare devices and ASM disks. Before using the software, you need to secure the ASM library driver for the corresponding platform. 2. ASM combines multiple disks to form a disk group. The disk group has the advantages of

4G, greatly improving the ability of file storage management. In earlier versions of ORACLE78, data files could be stored on file systems and bare devices provided by the operating system.ü Shared file system: With the development of IT system, simple bare device storage and operating system to provide file system storage can not meet the needs of business development, in order to improve the system's computing power, Oracle database has developed a variety of highly available architecture, The
