Problems solved by technology

[0003] During the operation of the job scheduling system, the core scheduling calls each job unit. Since the job scheduling system processes jobs at night, the problem that often occurs is that a large number of job units are instantly called up, and the concurrency required for the execution of a large number of job units Added up can cause the database to block or process slower

Abstract

The invention provides a concurrency degree control method and device in a job scheduling system. The method comprises the following steps: acquiring the total concurrency degree corresponding to a currently running job unit and the concurrency degree corresponding to each scheduled job unit; and controlling each called operation unit in an exclusive lock manner, and judging whether to allocate concurrency to the called operation unit or not according to the concurrency corresponding to each called operation unit, with the total concurrency corresponding to the currently running operation unitand the total concurrency of the instance nodes. Efficient concurrence can be carried out according to the concurrence degree of the database, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of job scheduling, in particular to a concurrency control method and device in a job scheduling system. Background technique [0002] The job scheduling system mainly checks whether the system can meet the resource requirements of user jobs according to the information in the job control block, and selects certain jobs from the backup queue of external memory and transfers them into memory according to a certain algorithm, and creates processes for them. , Allocate the necessary resources. The newly created process is then inserted into the ready queue, ready to execute. [0003] During the operation of the job scheduling system, the core scheduling calls up each job unit. Since the job scheduling system processes jobs at night, the problem that often occurs is that a large number of job units are called up instantly, and a large number of job units execute the required concurrency. Add up to cause databas...
