Design And Implementation Of High Availability Scheduling System Based On Distributed Architecture

Timing task scheduling is a very general software development and general requirements,but with the rapid growth of business,timing task number will have the massive growth,at the same time,with the improvement of timing task importance application scenario,the task of reliable trigger security is becoming more and stricter.The traditional scheduling system based on single machine mode cannot meet the demand.This article is mainly aimed at today's distributed application architecture mode,how to so lve the mass timing task of unified configuration management,how to provide timely and accurate high reliable trigger safeguard,and how to efficiently use application of cluster computing problems such as big tasks in parallel computing are discussed in this paper.Concerning the requirement of the distributed regular task scheduling business scenario,we have adopted a number of distributed Java development technology,design a peer,clustering trigger scheduling service core,used to horizontal extension service cluster to subdivision load growing huge task.Design the machine hot standby,rob trigger lock mode to provide timing task trigger to ensure high availability,designed a clustering support applications access at the same time,with the application of cluster dimensions to ensure the steady and efficient enforcement mechanism of task.By the mass,high availability,unified configuration management,task,load balance business scenarios,such as system architecture design,and the subsequent development testing,etc,finally realizes the function of a set of complete high availability timing task scheduling system based on distributed architecture.
