Comment on Spring Batch - Imperfect Yet Worthwhile by sactel

this is precisely my point - when it comes to practical scenarios like these there is not enough help or information out there (documentation / samples).

that’s why i feel in enterprise where batch is critical - batch platforms like datagrid, tivoli wlm etc would be a better strategy? just an opinion from enterprise architecture perspective, kindly note, though, i am myself am using spring batch framework

I don’t have convenient examples for either case. But in both cases I’d be thinking about approaching it by having a scheduled task check the job repository to see if the desired job was run successfully and, if not, restart it.

but talking about real practical scenarios like

*handling server crash (where the framework fails to store the state in job repos), how can this be handled; any concrete information that can be shared ?

*for job running say every 30 min (scheduled by external scheduler and batch started using commandjobrunner), what logic can be used to restart the failed job (automatically) . keeping in view job instance= job + job parameter; any sample for this

thanks in advance

Like Sam’s already said, Spring Batch seems to be the only game in town when it comes to free batch processing frameworks.

You’re right, Sam, in that Batch seems to have improved pretty drastically. My point was just that there’s a higher startup cost to get a custom batch job running than is typical for most other Spring endeavors I’ve tried. In the end, though, it’s all good.

I’ve been using Spring Batch for some time now & I find it pretty awesome. The frameworks got all the right components - specially when it comes to building scale-able batch jobs.

Its (the only?) industry standard batch framework available that I know of!

Quote
“I wasn’t alone in thinking the API left something to be desired.”

That article about three years old, and spring batch has come a long way since. There been loads of improvements between version 1.xx and version 2.xx

P.S. - You can also have a in memory repository and so the point of requiring a database is moot. But like you said, it’s definitely good to have it persisted in a database!

And finally do you recommend other alternatives for lightweigh batch-proccessing?

Comment on Four Java Surprises! by Vasanth

Vasanth — Mon, 09 Jan 2012 09:55:32 +0000

Bullets 2 and 3 was a surprise.. Thanks for that .
And regarding point 4 there is lot to ponder about Out of Memory,
Out-of-Memory error can happen for many reasons , like one quoted for heap size full , perm space full or even major collections i.e. garbage collection on Tenured generation made application irresponsive for longer duration. So , the idea is not that some space is full when Out-of-Memory error happens it can be due to garbage collection could not recover any space or the collection is taking longer time etc. It is better to anaylse the application with a profiler say Jconsole which is part of JDk 1.5 onwards.
Then we should look for
1. Spaces for each generation in heap i.e young and tenured
2. Major and Minor Collection frequency and its duration
2. Perm gen space etc.

Thanks everyone for the feedback! I’m glad this post has been helpful.

Also, I’m sorry (Nagababu, etc.) that I haven’t replied to specific questions. Maybe StackOverflow would be a better forum for quicker feedback? Thanks again.

When using on-line storey board, make sure it works well for all locations (it is a real pita to have one that is slow just because you aren’t co-located with server)
