JSR 352 :How to collect data from the Writer of each Partition of a Partitioned Step?

由 只愿长相守 提交于 2019-12-10 18:46:57
问题 So, I have 2 partitions in a step which writes into a database. I want to record the number of rows written in each partition, get the sum, and print it to the log; I was thinking of using a static variable in the Writer and use Step Context/Job Context to get it in afterStep() of the Step Listener. However when I tried it I got null . I am able to get these values in close() of the Reader. Is this the right way to go about it? Or should I use Partition Collector/Reducer/ Analyzer? I am using

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 9 months ago . A couple of questions regarding JSR 352, Spring Batch, and Java 1) When would someone use Java to build a batch JSR-352 application over Spring Batch? My initial take is it would require more coding in Java than Spring Batch. 2) Did version 7 of Java EE implement JSR-352? Or did

问题 What is the role of javax.transaction.global.timeout ? Do I need to implement the checkpointTimeout() method in CheckpointAlgorithm ? Is there anything at the server config level? How does this interact with whatever is set at the application level? 回答1: ( Edit 2016-12-02: Reworked with an explanation of the defaulting behavior when a timeout value of '0' is set for the application transaction). Overview Let me describe the application-level options and how that interacts with the server

JSR 352: Wildfly9 / JBeret - How to call a batch job that it is not contained at the same deployment file level

由 点点圈 提交于 2019-12-06 11:10:24
I have a WAR application that includes a JAR library. The JAR library contains the Batch Job and the Batch Artifacts ( META-INF/batch-jobs/... ). The WAR app includes this jar as a library and defines a JAX-RS Service that allows to clients to invoke the batch job calling the JobOperator Interface... When i run this deployment, the JSR 352 implementation (JBeret) keeps complaining that the Job cannot be found anyware when the JobOperator Interface is called... However, if the Batch Job and the Batch Artifacts are included as classes of the WAR deployment, everything runs smoothly... So, what

My initial take is it would require more coding in Java than Spring Batch. 2) Did version 7 of Java EE implement JSR-352? Or did it just come out with the spec and developers have to implement it? Whereas Spring Batch has implemented it, saving developers coding time? Overall this question is both subjective (subquestion 1) and lacks basic research (subquestion 2). I'll answer subquestion 2 since its not subjective. JSR-352 is part of the EE7

JSR 352 Restarting a job?

由 血红的双手。 提交于 2019-12-04 05:22:33
问题 When a job is restarted, only the failed partitions are run again. How do i run a successfully completed job again? Is there a difference between submitting a job again and restarting the job? i am using IBM's implementation of JSR 352 on Websphere Liberty. 回答1: Java Batch is designed so that when you restart a job instance, execution continues where you left off (in the previous failed or stopped execution). So typically this means two things: Within the job, you begin at the previously

Restarting the job should only
