Method and system for automatically optimizing configuration of database

Abstract

The present invention discloses an automatic optimization configuration method and system of a database, applied to a DB2 database. The method comprises: establishing a configuration base, a rule base, and a benchmark test case base according to a rule of the DB2 database; obtaining a configuration parameter of the configuration base according to a category in the configuration base; selecting a running benchmark test case from the benchmark test case base; setting a parameter value according to the rule base, and forming a configuration parameter combination according to a permutation and combination strategy; modifying a DB2 database startup configuration file according to each configuration parameter combination, and running the benchmark testing case, to obtain a test result of each configuration parameter combination, and performing analysis by using the test result of each configuration parameter combination according to work load corresponding to each configuration parameter combination, to obtain an analysis result; and obtaining an optimized configuration parameter combination of the DB2 database according to the analysis result. According to the automatic optimization configuration method, the configuration difficulty can be reduced.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method and system for automatically optimizing configuration of a database. Background technique [0002] The database performance gap before and after database configuration optimization may reach 10 times, or even 100 times. Moreover, whether the database configuration reflects the characteristics of the business system and whether it is optimally matched with the business load will directly affect the performance of the database. Therefore, database optimization configuration is a difficult problem. In particular, DB2 database has many configuration parameters, the number reaches more than several hundred, the dependencies between configuration parameters are not clear, and there are many configuration parameter combinations. Finding the best parameter combination suitable for business load is a difficult problem. If manual configuration is adopted, the database confi...
