Primary and standby services switching method and device

Abstract

The invention discloses a primary and standby services switching method and device. The method comprises the following steps: performing concurrent pressure performance test on each standby service, monitoring the service condition of a server resource where the standby service is located, and counting the Transaction Per Second tps in the concurrent pressure performance test process; when determining that primary and standby services switching needs to be performed, selecting a standby service, of which the service condition of the server resource is within a reasonable range, as a new primary service; when the service conditions of server resources where various standby services are located are within a reasonable range or within a same abnormal range, selecting a standby service with the highest tps as the new primary service; and when the service conditions of the server resources where various standby services are located exceed the reasonable range, taking a high-priority standbyservice with the service condition of the server resource exceeding the reasonable range as the new primary service according to the preset priority of the server resources. The primary and standby services switching method provided by the invention can automatically select a standby service with better performance as the primary service.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method and device for switching between active and standby services. Background technique [0002] In the Internet system, in order to meet high availability, system services are deployed on multiple servers, forming an architecture with one master and multiple backups. Under normal circumstances, the standby service is in the ready state (cold standby, hot standby, and warm standby). When the main service fails, the standby service will immediately replace it as the main service and start working. However, when there are more than two standby services, there is a switching election problem of which one to become the primary service. The switching process can be performed manually or automatically, but the reason for election is usually judged based on experience. Even if some automated processes can make some basic function judgments, they lack performance evaluation...

However, when there are more than two standby services, there is a switching election problem of which one to become the primary service

The switching process can be performed manually or automatically, but the reason for election is usually judged based on experience. Even if some automated processes can make some basic function judgments, they lack performance evaluation, so the new main service may have poor performance (including response time length, support for small number of concurrency, etc.), which cannot meet the needs of the current growing network users for performance experience
