What is the batch operations?

Batch processing is the execution of a series of programs ("jobs") on a computer without manual intervention.

Jobs are set up so they can be run to completion without human interaction. All input parameters are predefined through scripts, command-line arguments, control files, or job control language. This is in contrast to "online" or interactive programs which prompt the user for such input. A program takes a set of data files as input, processes the data, and produces a set of output data files. This operating environment is termed as "batch processing" because the input data are collected into batches or sets of records and each batch is processed as a unit. The output is another batch that can be reused for computation.

Batch operations are defined in batchOperationHandlers.lrbod file located under Definitions folder of your customization project.

Beginning with LPT version xxxx , there  kinds of batch operations that can be defined in an LPT project:

Batch Operation Types

public class OrdinaryBatch extends BatchOperationBase
{
      public int run()
      {
            return 0;
      }
      public void setParams()
      {
      }
}
