Abstract

The invention relates to a data processing technology, and discloses a database page fault tolerance method, which comprises the following steps of: performing page verification processing on a data page in a preset database to obtain a damaged data page, extracting a log file from the preset database, performing analysis processing on the log file to obtain a corresponding relation list of the data page and a page number, extracting the page number corresponding to the damaged data page from the corresponding relation list, skipping the page number corresponding to the damaged data page, and performing page repair processing on the damaged data page after the database is successfully started. In addition, the invention also relates to a block chain technology, and the damaged data page can be stored in a node of a block chain. The invention further provides a database page fault tolerance device, electronic equipment and a computer readable storage medium. The problem that a database cannot be normally started when a page is damaged can be solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a database page fault-tolerant method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The data of large-scale general-purpose relational databases is generally stored in non-volatile storage media. With the data explosion generated by information technology, the amount of data stored in modern databases is increasing, and frequent access to data leads to damage in storage media. The frequency of pages is getting higher and higher. Once bad blocks appear in the database data file, some database objects will be inaccessible at least, and the database system will not be able to start at worst. [0003] The existing method to solve the above-mentioned problem is to detect data bad blocks in real time by the file system of the operating system, and find bad blocks in advance, but this method cannot 100% prevent bad blocks from ...
