On-line switchover method for computer production system

Abstract

An online cutting-over method of a computer production system comprises the following steps of: (1) determining the data volume scale, business degree, network speed and log file size; (2) preparing a parameter file, configuring a monitoring file, transmitting basic data online and finishing test of new business procedures; (3) waiting for the arrival of cutting-over: the production system continuously operates business, the cutting-over system continuously receives and reuses the logs, the production system is kept synchronously with the cutting-over system to wait for the arrival of the cutting-over; (4) stopping the business in the front end of the production system, switching the database of the original production system to the cutting-over system rapidly and starting the businesses on the cutting-over system; and (5) configuring a rapid rolling-back measure after the failure of the cutting-over of online businesses; starting the process of remote filing on the cutting-over system; and switching the cutting-over system to the original production system if the failure of the cutting-over is detected. The finish time of the business of the invention is very short, thereby beingcapable of precisely evaluating the cutting-over time and having good data rolling-back capability.

Description

technical field [0001] The invention relates to a computer service cutover method. Background technique [0002] During the initial construction of the IT business system, the amount of data was very small, generally below 100G, mainly due to the fact that there was no data accumulation and the type of business was single. The functions of the IT system at that time were far less complex than they are now. [0003] With the development of several years, the customer's business has become more and more complicated, and the business data has accumulated more and more. For example, five years ago, when the business was initially established, the IT system only needed to provide front-end input, back-end query, and comprehensive report functions. , and the current IT system is omnipotent. In order to cooperate with the market promotion activities of mobile phones, a communication company has more than 1,000 billing types. In the past, you could not check the real-time phone bill...

AI Technical Summary

Problems solved by technology

[0069] In order to overcome the shortcomings of the existing computer service cutover method, such as too long downtime, inability to accurately estimate the cutover time, and failure to roll back if the cutover fails, the present invention provides a short service termination time, which can accurately estimate the cutover time, On-line cutover method of computer production system with good data rollback ability
