Embodiment Construction

[0016] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0017] Install and deploy in-memory databases and middleware applications on servers configured with large memory, then cache hotspot data (including read-only data and readable and writable data) stored in disk databases into memory, and configure corresponding data synchronization methods . At this time, if most of the data that the application needs to access the request is cached in the memory, then it only needs to operate in the memory, which eliminates the IO bottleneck caused by the disk operation, and at the same time, the changed data in the memory will be automatically synchronized To the disk database to ensure data reliability.

[0018] Step 1: Deploy in-memory database and middleware applications on servers with large memory;

[0019] Step 2: Configure the disk database, create a management user, and grant corresponding permissions;

[0020]...

Abstract

The invention provides a method for optimizing the performance of a disk database by the memory database technology. Memory database and middleware applications are installed and allocated on a server with a large memory configuration, hotspot data stored in the disk database, including read-only data and readable and writable data, are cached in a memory unit, and a corresponding data synchronization mode is configured to automatically synchronizing the varying data in the memory unit to the disk database, therefore, the reliability of data is ensured. By the memory database technology, the hotspot data stored on the disk are ached in the memory unit and meanwhile the application is modified to configure the original data request to the memory unit instead of the disk, although the operation of the disk is changed into the operation of the memory unit. Therefore, the I / O bottle neck in the conventional disk database system is eliminated and the performance of the system is greatly improved.

Description

technical field [0001] The present invention relates to computer database management technology, specifically a method for optimizing disk database performance using memory database technology. Background technique [0002] The database is an important part of a large-scale application system. With the enrichment of application system functions and the passage of time, the data in the database will increase to varying degrees. Traditional databases are disk-based databases, such as oracle, db2 , SQL Server, etc. When the data stored in the disk database reaches a certain level, the IO bottleneck will appear in the database, the performance will be seriously degraded, and the application access will also wait slowly. [0003] Faced with this situation, in-memory databases and applications can be deployed on large-memory servers, and then use in-memory database technology to cache hotspot data stored in disks into memory, so as to eliminate disk IO bottlenecks and improve sys...
