Problems solved by technology

[0002] The database high-availability middleware (Pgpool II) has realized the high-availability cluster of the object-relational database (PostgreSQL) in the basic active-standby switching mode. Pgpool II cannot automatically restore the database when the network is interrupted
[0003] In the existing related technologies, when encountering the above situation, it is necessary to manually participate in fault recovery, resulting in poor timeliness of fault recovery

Abstract

The invention provides a failure recovery method and device and a computer device. The failure recovery method comprises the steps that the network connectivity of a mainframe where a local database is located is monitored; if the mainframe where the local database is located is connected, the running conditions of the local database are obtained; according to the running conditions of the local database, when the running conditions of the local database are abnormal, the abnormal running status of the local database is recovered through high-availability middleware of the database. Database recovery actions can be automatically executed in various abnormal states, man-made operation is avoided, and the timeliness of failure recovery is improved.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular to a fault recovery method, device and computer equipment. Background technique [0002] The database high-availability middleware (Pgpool II) has realized the high-availability cluster of the object-relational database (PostgreSQL) in the basic active-standby switching mode. Pgpool II cannot automatically restore the database in the event of a network outage. [0003] In the existing related technologies, when the above situation is encountered, it is necessary to manually participate in fault recovery, resulting in poor timeliness of fault recovery. Contents of the invention [0004] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, the first purpose of this application is to propose a fault recovery method to automatically execute database recovery actions in various ab...
