Distributed system node configuration updating method, application node and control node

Abstract

The invention discloses a distributed system node configuration updating method, an application node and a control node, and the method comprises the steps: reading configuration information from a database when a configuration updating notification broadcasted by the control node through a dubbo service is received, and starting timing; if the configuration information is successfully read, updating the configuration information to a local cache; if the configuration information fails to be read or the configuration information fails to be updated to the local cache, judging whether the operation time from the timing starting moment to the current moment exceeds a time threshold value or not; and if the time exceeds the time threshold, triggering a communication timeout mechanism with thecontrol node, so that the control node confirms that the application node fails to update the configuration according to the communication timeout mechanism. According to the method, the problems that the system complexity is improved and the timeliness of node configuration updating cannot be guaranteed in order to realize node configuration updating at present can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a distributed system update node configuration method, an application node and a control node. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] For a distributed architecture system, the same application may be deployed on multiple nodes, and each node can process business requests according to the same business logic. If it is necessary to modify the system parameters cached in the memory of each application node, the system parameters in the memory of each node in the distributed architecture system need to be refreshed synchronously to ensure that when a new business request comes in, no matter which node is routed for processing, the obtained The processing results are the s...
