Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
As mentioned above, the distributed batch Job scheduling of the core bank X86 system is realized by adopting an Elastic-Job-Lite framework which is a lightweight decentralized solution and provides a coordination service of distributed tasks in the form of jar packages. Under the framework, the time for starting execution of each job is set, and then the jobs are scheduled to be executed in sequence according to the timing sequence of each job. However, the method cannot accurately correspond to the actual operation condition, the problems that the subsequent operation starts after the previous operation is not completed easily occur, the scheduling accuracy of the batch operation is low, and the normal operation of the system is seriously influenced.
In order to implement accurate scheduling of batch jobs, corresponding to an actual job running situation, avoid a problem that a preceding job starts running without completing the following job, and ensure normal running of a system, an embodiment of the present invention provides a batch job scheduling processing method, as shown in fig. 1, which may include:
102, determining one or more previous jobs of the jobs corresponding to each unexecuted state label according to the execution sequence data;
103, scheduling each job corresponding to the unexecuted status label until the executed status label of each job is the executed status label, according to the following steps:
determining whether to trigger job scheduling according to the execution state tags of one or more previous jobs corresponding to the jobs; and if the job scheduling is triggered, updating the execution state label of the job to the executed state label.
As shown in fig. 1, in the embodiment of the present invention, an execution status tag of each job in a plurality of jobs and execution sequence data of the plurality of jobs are obtained, where the execution status tag is: an executed state tag or an unexecuted state tag; determining one or more previous jobs of the jobs corresponding to each unexecuted state label according to the execution sequence data; scheduling the job corresponding to each unexecuted state label until the executed state label of each job is an executed state label: determining whether to trigger job scheduling according to the execution state tags of one or more previous jobs corresponding to the jobs; and if the job scheduling is triggered, updating the execution state label of the job to the executed state label. According to the method and the device, the front-back relation of the operation is determined through the execution sequence data, and then whether the scheduling of the operation is triggered or not is determined according to the execution state label of the front-back operation corresponding to each operation, so that the problem that the operation is started when the front-back operation is not completed is solved, the accurate scheduling of batch operation is realized corresponding to the actual operation condition of the operation, and the normal operation of the system is guaranteed.
In specific implementation, an execution status tag of each job in a plurality of jobs and execution sequence data of the plurality of jobs are obtained, wherein the execution status tag is: an executed state tag or an unexecuted state tag.
In an embodiment, the executed state tag comprises: an executed tag and a timestamp, wherein the timestamp is an execution date.
In specific implementation, one or more previous jobs of the jobs corresponding to each unexecuted state label are determined according to the execution sequence data.
In an embodiment, after obtaining the execution status tag of each of the plurality of jobs and the execution order data of the plurality of jobs, one or more subsequent jobs of each unexecuted status tag corresponding to the job may be determined according to the execution order data. The execution sequence data is association structure data obtained from the context between jobs.
In an embodiment, the execution state tag of each of the plurality of jobs and the execution order data of the plurality of jobs are stored in a data table. The data table field includes: job name, execution date, unique serial number, execution state tag, current execution state start time, current execution state end time, list of successor job serial numbers, executed flag, and/or unexecuted flag. By the data table, the execution sequence data of the operation can be obtained, and the maintenance is convenient; and secondly, the execution state label of each job can be obtained, and the execution state of the tracking job is convenient to implement.
In specific implementation, scheduling processing is performed on the job corresponding to each unexecuted status tag according to the following steps until the execution status tag of each job is an executed status tag:
determining whether to trigger job scheduling according to the execution state tags of one or more previous jobs corresponding to the jobs; and if the job scheduling is triggered, updating the execution state label of the job to the executed state label.
The inventor finds that the existing batch job scheduling method cannot accurately correspond to the actual job running condition, the problem that the subsequent job starts to run when the previous job is not completed easily occurs, and the normal running of the system is seriously influenced due to low batch job scheduling accuracy. Therefore, the embodiment of the invention determines the tandem relation of the operation through the execution sequence data, and then determines whether to trigger the scheduling of the operation according to the execution state label of the tandem operation corresponding to each operation, thereby avoiding the problem that the operation is started when the tandem operation is not completed, realizing the accurate scheduling of batch operation corresponding to the actual operation condition, and ensuring the normal operation of the system.
In an embodiment, for each job corresponding to the unexecuted status tag, after determining one or more jobs preceding the job, determining whether to trigger job scheduling is as follows:
if the execution state label of one previous job corresponding to the job is an executed state label, or the execution state labels of a plurality of previous jobs corresponding to the job are all executed state labels, triggering job scheduling;
and if the execution state label of one previous job corresponding to the job is an unexecuted state label or at least one of the execution state labels of the multiple previous jobs corresponding to the job is the unexecuted state label, not triggering the job scheduling.
In the embodiment, before scheduling processing is carried out on each job corresponding to the unexecuted state label, whether the execution state labels of one or more previous jobs corresponding to the job are updated or not is determined; and if the execution status labels of one or more previous jobs corresponding to the jobs are updated, scheduling the jobs. If the execution status tags of one or more previous jobs corresponding to the job are updated, which indicates that the execution status tags of the previous jobs are updated from the unexecuted status tags to the executed status tags, the job has a chance to be scheduled, and if the execution status tags of one or more previous jobs corresponding to the job are not updated, which indicates that the unexecuted status tags in the previous jobs are not updated to the executed status tags on the basis that the previous scheduling is not triggered, the job is not scheduled at this time, so that the scheduling process can be omitted, and the redundant processing process can be effectively reduced.
In an embodiment, the execution state tag update of the job may be implemented by using a Zookeeper cluster. Zookeeper is a piece of software that provides a consistent service for distributed applications, using Watcher to perceive event information, such as: connection timeouts, node data changes, node changes, etc. Each job has a corresponding node on the Zookeeper, and the data in the corresponding node is modified when the job updates the execution state label each time, and the modification also triggers the scheduling processing of the job corresponding to each unexecuted state label.
It should be noted that, in the initial state, the execution status tags of all jobs are all unexecuted status tags, and the Job without a preceding Job uses the timing interface provided by Elastic-Job to time-trigger one or more jobs whose execution sequence is the top one. After the one or more jobs are scheduled, the execution status tag is updated to the executed status tag, and at this time, the batch job scheduling processing method in the embodiment of the present invention is applied to the jobs which are still the unexecuted status tag for processing until the execution status tag of each job is the executed status tag.
Based on the same inventive concept, an embodiment of the present invention further provides a batch job scheduling processing apparatus, as described in the following embodiments. Because the principles of solving the problems are similar to the batch job scheduling processing method, the implementation of the device can refer to the implementation of the method, and repeated details are not repeated.
