Abstract

The application discloses a method and a device for simulating network anomaly and testing automatic switching of database faults. One specific embodiment of the network anomaly simulation method comprises the following steps: receiving a to-be-sent data package; determining the current simulation task including any one of the following preset tasks: packet loss status simulation and network delay status simulation; and if the simulation task is the network delay status simulation, sending to-be-sent data to a receiving end corresponding to a sending end according to the correspondence rule of the network address of the to-be-sent data sending end and the network address between the preset sending end and the receiving end after receiving the to-be-sent data packet for a preset time period. According to the embodiment, the network anomaly of the network delay type between the sending end and the receiving end is simulated, so that the automatic switching of database faults triggered by the network anomaly of the network delay type can be tested.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of software technology, in particular to a test method and device for network anomaly simulation and database fault automatic switching. Background technique [0002] In the database storage service, for data security, a master database and multiple slave databases are usually deployed. When the master database fails (such as a network exception), the slave database needs to be automatically promoted to the master database to continue working. A system using this database storage service architecture can be called a system based on a master-slave database architecture. In order to test the automatic database failover, it is necessary to simulate various database failure scenarios to trigger the execution of the automatic database failover. For the scene of database failure caused by network abnormality, the simulation method in the prior art is to trigger t...
