Hi can you add a tutorial on spring batch process read the input from ibm websphere mq and inserting into databse
Hello gocnhintangphat.com,
Regarding Job Restart:::
can you add a tutorial on spring batch failed scenario(abnormal termination :jvm crash or power off) when the job is restarted then job start processing the input file where it has left off in the previous execution which was failed.
consider the scenario, parsing flat file line by line and printing or storing in database. Ex: input file contains 100000 records, 60000 records are processed successfully what i mean inserted into database successfully, but in the middle job crashes. I want to restart the batch and batch should start picking recrods from line 60001 (line number) but not from starting.
Thanks in-advance
I need to implement a file locking mechanism such that while a particular process is reading the file, no other process is able to read it. Using FileLock from Nio Api is not working when I am deploying the application in a local server, can you provide a proper solution for this?

I thought these collections were a great introduction to Spring Batch. I am still strugging to over-come the ORA error I encounter using Oracle for my job repository and I am trying to use the Spring Batch Admin from the instructions I found here: http://stackoverflow.com/questions/19840826/how-to-get-a-stable-release-of-spring-batch-admin And I have been successful at creating the appropriate batch-oracle.properties which I placed under the spring-batch-admin-sample (sub-directory within the set of things I downloaded per that link) under src/main/resources. I gather my problem is related to the transaction level for create, but I am uncertain where to provide whatever *.xml override or *.properties override as I see suggested in a few references regarding the: SQL
