The main Moto is need to transfer the data from one data base to another date bade for that am going to write a batch program but spring batch is creating tables in both the data bases how to stop that
I would like to know if there is a way to load a large data in csv format, and then save only a part (ex: 50-100 lines) in csv format.
CSV in reality is just text, you can turn your image into text byte but will not be usable as CSV.
If your data is too large and you can't load everything at once, you could read the csv file line by line and get the data that you want.
How can I loop one csv file to another csv file in JMeter, where the first csv file contains all the login data and the other csv file contains the transaction data. I am supposed to run where 1 teller should process 30 transaction.
Go for __CSVRead() function.
You will not be able to use CSV Data Set Config as it is a Configuration Element and according to the JMeter Test Elements Execution Order all the configuration elements are being initialised at the very beginning of the test while your requirement is to read data based on user dynamically.
Check out How to Pick Different CSV Files at JMeter Runtime article for comprehensive information on using __CSVRead() function
I am working on a spring batch application where I read from a stored procedure from database and write it to an xml file.
My writer is a org.springframework.batch.item.xml.StaxEventItemWriter
I am trying to implement a situation in which I find duplicates using this method - Spring Batch how to filter duplicated items before send it to ItemWriter
However, in my situation I don't want to skip a duplicate but override an existing record written to XML by my ItemWriter.
How can I achieve it ?
We have a use case where we receive data in flat files which we load into an Oracle DB using Spring Batch. Post data load in Oracle, we have to distribute the data in form of flat files to several consumers. The data selection criteria depends on some pre-decided values in some fields of the data.
We have a design in place which generates a list which contains objects that can be passed to a Spring Batch job as job parameter to generate the flat files needed to be sent to the data consumers.
Using a Splitter component, I can put the individual objects into a channel and plug a JobLaunchingGateway to launch a batch job to generate the flat file.
Need help on how I can launch multiple batch jobs in parallel using JobLaunchingGateway so that I can generate files in parallel.
A setup is already in place to FTP the files to consumers. We do not need to worry about that.
Use an ExecutorChannel with a task executor before the JobLaunchingGateway.
