Problems solved by technology

[0003] (1) In the related industries whose business depends on the date, in order to ensure the reliability of date switching, the host database and preset programs used to realize the date switching operation need to run on high-performance and high-reliability high-end servers, so as to ensure The low failure probability of the date switching process and the high reliability of the date switching results, which will inevitably lead to excessive costs
[0004] (2) The date switching operation needs to ensure that the date is switched backwards, and the host that implements the date switching operation needs to perform the date switching operation according to the network time. If the network time changes slowly due to technical reasons and the time in the host database changes quickly, the network time If it lags behind the time in the host database, switching the date in the host database according to the network time may cause the date to roll back forward, resulting in an error

Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0047] An embodiment of the present invention provides a time node switching method, such as figure 1 As shown, the method includes:

[0048] S101. Regularly request the standard time from the time service server.

[0049] S102. Maintaining that the system time of the device where the switching service process is located and the system time of the device where the data center is located are consistent with the standard time.

[0050] The standard time provided by...

Abstract

The invention provides a time node switching method and a time node switching system. A plurality of switching service processes perform preemptive change operation on a time node of a data center. The fault of a certain switching service process does not affect finishing of a time node switching task. A success rate of an integral switching task does not reduce on the condition that common hardware with a low cost is used for performing service switching. The switching service processes and the data center timely and independently perform time synchronization with a timing server. Furthermore, the switching service processes and the data center further ensure system time correctness of equipment with the switching service processes and the equipment with the data center through mutual time verification, thereby further improving time node switching reliability.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a time node switching method and system. Background technique [0002] In today's society, the management of time nodes, as one of the important contents of data management and engineering management, has penetrated into various fields of national life. Common time nodes include half-day (12-hour system), date (24-hour system), week (7* 24-hour clock), month and year. As one of the main contents of time node management, the importance of accurate switching of time nodes is self-evident. However, there are some defects in the existing time node switching methods. Take date switching as an example: [0003] (1) In the related industries whose business depends on the date, in order to ensure the reliability of date switching, the host database and preset programs used to realize the date switching operation need to run on high-performance and high-reliability high-end servers...
