Problems solved by technology

[0010] In the mode of active and standby machines, only the main machine provides business services to the outside world, while the standby machine is only used to keep in sync with the main machine's in-memory database, and the main machine's in-memory database is performing operations such as zero-level backup, dirty data refresh, and logical log writing. At this time, all external commands to the data in the memory database must be terminated. Only after these operations are completed can the function of executing external commands be resumed. During this period, the performance of the billing system will be greatly affected, resulting in intermittent blocking of the memory database. question

Embodiment Construction

[0037] Various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Take the implementation of memory data backup in a converged billing system (CBE, Convergent Billing Engine) as an example.

[0038] The CBE system is a real-time billing system based on an in-memory database. The CBE system uses memory database technology to improve the real-time response performance of the system. The memory database maps all the data in the common database tables of the system to the shared memory of the host, and establishes memory indexes on the key fields of the database tables. , to improve the real-time access performance of the system to key data.

[0039] The CBE system implements the backup of data in the memory database by means of master and backup machines. The main and standby machines initially store the common data in the same memory database table in the memory. Wherein, the standby machine implements zero-le...

Abstract

The invention discloses a method, device and system for implementing memory data backup. And the method comprises: receiving logic log generated by memory database of a host computer; according to the logic log, synchronously backuping the memory data in the host computer, and making backup operation on the memory data. And the device comprises: receiving unit and memory database, where the memory database comprises: synchronizing unit and backup unit. And the invention can assure the memory database in the host computer real-timely supplies data operation to the outside and can not interrupt by the effect of the backup operation, improving working performance of the host computer and raising working efficiency of the host computer.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method, device and system for realizing memory data backup. Background technique [0002] In the field of communication technology, for network operators, the billing system is an important part of the network, and the real-time performance requirements for the billing system are very high; whether the billing system can operate normally, that is, the security of the billing system It is related to the interests of all users in the network. [0003] Therefore, in order to realize the real-time response of the billing system, a billing system based on the memory database is developed. The billing system based on the memory database can respond to external commands quickly and in real time, and perform various operations such as querying, deleting, and modifying data in the memory database. [0004] The billing system based on the memory database, because all the data of ...
