利用Python语言实现软件系统准热备的一种方法——以JOPENS0.5.2流服务器为例

Software System Quasi-hot Standby Using Python:Taking the JOPENS0.5.2 Streaming Server as an Example

为提升数字地震台网中心软件系统运行的安全性,降低故障排除时间,以JOPENS0.5.2系统的流服务器为例,介绍了一种利用Python语言实现流服务器准热备的方法。经实际检验,采用该流服务准热备方法后,其服务器切换用时在30~210 s之间,较人工处理具有较大优势。该方法还可在一定程度上推广至其他需要热备的软件系统。

In order to improve the software system operation safety of the seismic network and reduce the troubleshooting time,we introduce an implementation method for quasi-hot standby of streaming servers using Python—taking the streaming server of JOPENS 0.5.2 system as an example.The test results show that the server switching time is between 30 to 210 seconds,which is better than manual processing.This approach may be extended to other software systems that require hot standby.
