Problems solved by technology

[0002] At present, the database occupies an important position in information technology. With the rapid development of information technology, the database plays an extremely important role in daily work, business activities, and even people's lives. However, due to its own working principle, the computer system Due to the limitation, failures of all similar items often occur, and the database system is no exception. Problems such as data deadlocks and server crashes often occur. If there is no good emergency response preparation, various problems will be caused , causing heavy losses

Embodiment Construction

[0013] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0014] A database automatic recovery method adopts two groups of cluster database systems, one group is a main database, and the other is a hot backup database, and the two groups of database systems are respectively installed in different data storage servers, including the following steps:

[0015] A. When the main database is working normally, the main database is fully backed up to the backup database at regular intervals;

[0016] B. After the backup, the main database work is recorded and stored in chronological order;

[0017] C. Monitor the working status of the database. When the primary database system crashes, enable the backup database and convert the backup database to the new primary database, and ...

Abstract

The invention discloses an automatic recovery method for databases. The method has the advantages that two cluster hot backup systems are adopted to carry out backup of a master database at regular times, record data operation and save the recorded data operation to a work log; under the circumstances of a database breakdown, downtime and the like, a standby database is immediately enabled, and the working status is recovered back to the working status at the occurrence of the breakdown according to the work log, so that the operations of the databases can be connected in a seamless manner, and the system stability is ensured.

Description

technical field [0001] The invention relates to the field of databases, in particular to an automatic database recovery method. Background technique [0002] At present, the database occupies an important position in information technology. With the rapid development of information technology, the database plays an extremely important role in daily work, business activities, and even people's lives. However, due to its own working principle, the computer system Due to the limitation, failures of all similar items often occur, and the database system is no exception. Problems such as data deadlocks and server crashes often occur. If there is no good emergency response preparation, various problems will be caused , causing heavy losses. Contents of the invention [0003] The object of the present invention is to propose a database automatic recovery method to solve the above problems in order to realize the advantages of timely resolution of database failures. [0004] In ...
