Running program hotfix method and apparatus

Abstract

The invention discloses a running program hotfix method and apparatus. The method comprises the steps of querying configuration information according to a data access request; judging whether the configuration information includes update configuration information of a program providing a data access service or not, wherein the update configuration information records information of replacing a first program file with a second program file subjected to fix; if a judgment result is yes, obtaining and loading the second program file according to the update configuration information; and running an executable program of the second program file in a running system to make a response to a data access request. The problem of relatively long time of a running program fix process in the prior art can be solved; the running program fix duration can be greatly shortened; the realization process is simple and the operation is flexible; and lots of convenience is brought for program development andusers during use.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for hot repairing running programs. Background technique [0002] At present, when there is a problem with the online running program on the server side (for example, there is a bug in the running program file), since the repair process usually needs to go through the process of the program's development environment, pre-release environment, and release in sequence, there is a time-consuming process for the program repair process. The problem of long time (usually more than half an hour, when there are many machines running, it will take several hours or even more time), brings a lot of inconvenience to program development and user use, and may also cause relatively long time to developers. Large asset loss and loss of reputation. [0003] In view of the above existing problems, in the prior art, the running program is dynamically updated through the hot de...

Problems solved by technology

However, hot deployment technology and hot loading technology have the following limitations: hot deployment technology (such as tomcat hot deployment module) usually needs to reload the entire application, and the time it takes is almost the same as restarting the server. The time is too long; and the hot loading technology usually has relatively large restrictions on program modification (for example, Hotswap only allows modification of the method body, does not allow adding new protocols, does not allow new fields, methods, and does not allow modification of method signatures, etc., which is extremely large. Limits the type of problem solving), complex installation (such as JRebel and jvm strong coupling, installation is more complicated), inconvenient maintenance (such as OSGi) and scripts are not applicable (such as Groovy can only be used to fix its own script problems, for other scripts Not applicable) and many other problems, and on this basis, it is impossible to effectively solve the problem that the running program repair takes a long time
