Abstract

The invention provides a redundancy method and device for data files in a database. The method comprises the steps of adding mirror data files to master data files in the database; synchronizing data in the master data files to the mirror data files; and setting a concurrency control mechanism for the master data files and the mirror data files. Through application of the method, mirror functions is added to the data files in the database, when a problem occurs in one data file in a mirror, the other normal data file can provide data read / write service, so the security of the data is improved, the data loss problem generated when a fault occurs in a memory server or the memory server is replaced is avoided, the normal use of a business system is not influenced, and the availability of the database is improved.

Description

technical field [0001] The invention relates to the technical field of database security, in particular to a redundant method and device for database data files. Background technique [0002] Currently, large-scale relational databases do not have a data file-based redundancy mechanism, which identifies the uniqueness of the data file through the data file path and name, so each data file in the database is unique, and there is no other and this data file The content of the data files is exactly the same, and the data files are mirror images of each other, that is, the database does not have the function of redundant data files. [0003] When a data file in the database is lost or damaged, because the content in the data file cannot be read, the database cannot be used normally, thereby affecting the normal operation of the business system. However, it takes a long time to recover data files in the form of physical backup, and if many or all of the lost data files are lost,...
