Problems solved by technology

[0004] The existing method of synchronizing from the emergency database to the production database, because it uses sql records, increases the database processing logic, increases the number of database processing times, and the time for data synchronization is relatively long, resulting in the probability of errors during processing also relatively large

Abstract

The invention relates to a database emergency handling method and system. The method comprises the following steps of: detecting an operational state of a production library; when the production library is in a normal state, synchronizing data of the production library into an emergency library in real time; when the production library has a fault, switching the production library to the emergency library, and switching a database connection address of an application system to the emergency library; and when the production library returns to the normal state, switching the emergency library back to the production library, and reversely synchronizing data read-write, which is performed in the emergency library within the fault time period of the production library, into the production library. According to the method and the system, in a mode of reverse synchronization from the emergency library to the production library by use of oracle Active Data Guard, data operation records of the emergency library are reduced, and the processing time based on sql covering data in the past is effectively shortened. Furthermore, data covering modes for all services are same, so that the operation is convenient and quick, and each system is not needed to process covering data.

Description

technical field [0001] The invention relates to the field of computers, in particular to a database emergency processing method and system. Background technique [0002] Databases used by many commercial systems, including production and emergency databases. When the database is running normally, the system accesses the production database. When the production database fails due to a problem, the system will switch to the emergency database. After the production library can be used normally, switch the system to the production library. The process of database switching needs to keep the data in the production database and emergency database consistent. [0003] At present, the data in the production database is consistent with that of the emergency database. Through oracleActiveDataGuard technology, the data in the production database can be synchronized to the emergency database in real time. However, when the system uses the emergency database, it is necessary to record ...
