spring-batch

I just want to know if there is a "JOB" scope in spring batch, like the "STEP" scope ? If there is not, should we develop our custom scope, or is there a better alternative ? Thanks in advance. Raphaël Brugier A jira has been opened some times ago on the spring batch issues tracker regarding this issue: https://jira.springsource.org/browse/BATCH-1701 A pull request has been submitted as well, hopefully it will be merge soon, because I have this use case too: https://github.com/SpringSource/spring-batch/pull/41 There are multiple workarounds in the mean time, each with its drawback, see this

I'm trying to configure spring batch inside spring boot project and I want to use it without data source. I've found that ResourcelessTransactionManager is the way to go but I cannot make it work. Problem is I already have 3 another dataSources defined, but I don't want to use any of them in springBatch. I've checked default implementation DefaultBatchConfigurer and if it is not able to find dataSource it will do exactly what I want. Problem is I've 3 of them and dont want to use any. Please dont suggest to use hsql or other in memory DB as I dont want that. Nandish I got around this problem

firstly, thanks for attention,in my spring batch project defined many jobs , for example: <batch:job id="helloWorldJob1" job-repository="jobRepository"> <batch:step id="step1" > <batch:tasklet> <batch:chunk reader="itemReader1" writer="itemWriter1" processor="itemProcessor1"> </batch:chunk> </batch:tasklet> </batch:step> </batch:job> <batch:job id="helloWorldJob2" job-repository="jobRepository"> <batch:step id="step1" > <batch:tasklet> <batch:chunk reader="itemReader2" writer="itemWriter2" processor="itemProcessor2"> </batch:chunk> </batch:tasklet> </batch:step> </batch:job> <batch:job id=

Use case: A one-time read of data set X (from database) into a Collection C. [Collection size could be say 5000] Use Collection C to process/enrich items in a Spring Batch Step (say enrichStep) If C is much greater than what can be passed via ExecutionContext, how can we make it available in the ItemProcessor of the enrichStep? Luca Basso Ricci In your enrichStep add a StepExecutionListener.beforeStep and load your huge collection in a HugeCollectionBeanHolder bean. In this way you will load collection only once (when step start or re-start) and without persist it into execution context. In

I have dao which basically inserts a record into a table using hibernate, this dao is marked by @Transactional annotation with propogation-NESTED , and I have service which makes some other stuff and then invokes my dao. My service is also annotated with @Transactional with propagation-REQUIRED . I call service in a loop. Does my inserts on my dao works in batch or one by one? How can I be sure that they work in batch? Does hibernateTransaction manager manage batch inserts? I am using Oracle DB. I have set following property and my performance increased; hibernate.jdbc.batch_size=50 I am no

Spring batch had it's own database schema. My application has it's own database schema. I want to keep these separated into different databases so the spring-batch tables are not inside my applications database. By default spring-boot only supports connection to a single database.

Well this is how I did it. In application.properties ### Database Details datasource.app.driverClassName=oracle.jdbc
