Embodiment 1

[0044] This embodiment provides a method for controlling database backup performance, which is applied in the data interaction process between the media management process and the backup process. The media management process is used to obtain the backup data from the database. The backup The process is used to share backup data from the medium management layer process and send it; the control system of the database backup performance includes the following steps:

[0045] Between the media management layer process and the backup process, create a data object pool for assisting the media management layer process and backup process data interaction; the data object pool includes at least one shared memory for caching backup data unit, the shared memory unit has backup data cached, the readable semaphore of the shared memory unit can be read, there is a data memory that can cache the backup data in the shared memory unit, and the writable semaphore of the shared memory unit ;

...

Embodiment 2

[0072] This embodiment provides a database backup performance control system, and the control system is applied in the data interaction process between a media management layer process and a backup process. During the interaction process, the media management layer process is used to obtain backup data from a specified database, and cache the obtained backup data in the created data object pool. In this embodiment, the specified database is an Oracle database. The backup data is used to obtain backup data from the created data object pool, and send the obtained backup data to a third-party media pool. see Figure 5 , is a schematic diagram showing the principle structure of a control system for database backup performance in an embodiment. Such as Figure 5 As shown, the database backup performance control system 2 includes: a creation module 21 and an operation module 22 .

[0073] The creating module 21 is used for creating a data object pool 1 between the media manageme...

Abstract

The invention provides a method and system for controlling database back-up performance and a server. According to the controlling system, a data object pool used for assisting data interaction between a media management layer process and a back-up process is created, and the data object pool includes at least one shared memory unit used for caching back-up data, readable signal amount of readable shared memory units and a writeable signal amount of the shared memory units, wherein the back-up data is cached in the shared memory units and the data memory of cacheable back-up data exists in the shared memory units; the readable signal amount of readable back-up data and the writeable signal amount of writeable back-up data in the data object pool are read, and according to the obtained readable signal amount of the readable back-up data and the obtained writeable signal amount of the writeable back-up data, the media management layer process and the back-up process execute asynchronous operation on the back-up data respectively. On the whole, the Oracle single channel back-up performance is improved, and the Oracle big datavolumn back-up speed is improved.

Description

technical field [0001] The invention belongs to the technical field of structured data protection, and relates to a control method and system, in particular to a database backup performance control method, system and server. Background technique [0002] Oracle provides a set of media management layer interfaces (Media Management Layer (MML) API), allowing third-party vendors to build their own media managers (Media Manager). A common practice is to obtain backup data from Oracle through MML, and then share it with the backup process of a third-party vendor, and the backup process sends the backup data to the media pool. [0003] The backup speed of the Oracle server can reach hundreds of gigabytes per second. That is to say, the message communication between the MML process and the backup process is under great pressure, and a large amount of data needs to be shared every second. The performance loss caused by message communication between processes directly affects Oracl...
