Embodiment Construction

[0057] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0058] In the communication industry, TimesTen memory database is used in billing system. Since the billing system involves customer billing, voice communication, short and multimedia messages, GPRS (General Packet Radio Service, general packet radio service technology) Internet access (especially 4G), the customer sensitivity is very high. Affect customer perception, affect the company's business and reputation.

[0059] The TimesTen database product itself does not provide table statistics collection function, and statistics collection itself needs to consume certain resources. Under normal circumstances (business peaks), statistics collection cannot be performed on database table objects, which will affect the normal operation of the system. Therefor...

Abstract

The invention provides a method and a device for processing faults of a database, relates to the field of databases and aims at solving the problem that existing memory databases cannot timely monitor and process faults of the databases. The method include: acquiring a first detection value of a preset monitoring event to detection on database running efficiency in the running process of the database; determining a first running state of the database according to the first detection value, and statistically collecting an intermediate temporary table of the database for the first time when the first running state of the database is in a fault state; acquiring a second detection value of the preset monitoring event to detection on database running efficiency after first-time statistical collection is performed on the intermediate temporary table of the database; determining a second running state of the database according to the second detection value, and statistically collecting a whole database table of the database for the second time when the second running state of the database is in a fault state. By the method and device, faults caused by untimely table statistical collection can be timely monitored and processed, so that processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method and device for processing database faults. Background technique [0002] TimesTen memory database is a database in which all data and transaction change operations are completed in memory during the running process. Memory is currently recognized as the fastest storage device in the industry, so TimesTen memory data is often used in scenarios that require very high timeliness of business response. In the current communication service system, the billing system has very high service response requirements, and generally requires the response to be completed within 1 second. Therefore, in the communication industry, TimesTen memory database is used in the billing system. [0003] However, the Timesten database product itself does not provide the statistical collection function of the table, and whether the statistical information of the table is accurate plays a decisive role in ...
