spring batch-processing
I am using spring batch to parse files and I have the following scenario:I am running a job. This job has to parse a giving file. For unexpected reason (let say for power cut) the server fails and I have to restart the machine. Now, after restarting the server I want to resume the job from the point which stopped before the power cut. This means that if the system read 1.300 rows from 10.000 now have to start reading from 1.301 row.How can I achieve this scenario using spring batch?About configu

java java-ee log4j batch-processing
We have a weblogic batch application which processes multiple requests from consumers at the same time. We use log4j for logging puposes. Right now we log into a single log file for multiple requests. It becomes tedious to debug an issue for a given request as for all requests the logs are in a single file. So plan is to have one log file per request. The consumer sends a request ID for which processing has to be performed. Now, in reality there could be multiple consumers sending the request ID

java-ee architecture iteration batch-processing recovery
Our system is processing more than 100 000 subscribers. On a weekly basis another external application builds special file(s) containing users’ financial information with >100 000 rows. Our application should parse it and process every record (send sms/mms/email in our case). Of course, these operations are quite time consuming, so we’re doing them asynchronously via JMS.But first we need to put all the records to the queue. Performance test showed that it takes around 30-40 minutes or even mor

I have a complex string I’m trying to parse. I have a short subroutine to fine the index of two specific characters, and I need the string in between. So the question is: How do I use variables inside string manipulation of another variable?Here’s some sample code:@ECHO offset start=2 set end=5 set str=Hello Worldecho %str:~2,5% echo %str:~%start%,%end%%How do I get the second echo to display what the first echo displays? (right now second echo is just showing what I want, it’ll crash as is)

I got a quite long windows batch script. In the middle of it there’s a section using appcmd to detect the root path of a site in my IIS. That section runs fine when executed standalone. But when I execute the whole batch, this section could fail to detect the site path once in a while. I am totally confused by this unreliability issue. Have anyone met this before?ThanksSolutionIt seems that there’s some delay between a variable declaration and its coming into effect. I changed the order of some
