Payment Predictor Multiprocess Job

The Payment Predictor multiprocess job (ARPREDCT) is a shell process that runs multiple subprocesses that process different sets of data concurrently. The multiprocess job contains two subprocesses that run sequentially. The second subprocess runs multiple child processes in parallel when you set up parallel processing for the Payment Predictor process.

• The AR_PREDICT1 Application Engine process gathers the data for the process run, determines how many rows each parallel process should process, and starts each parallel process.

• The Payment Predictor multiprocess job (AR_PP) starts after AR_PREDICT1 and calls each of the child processes that you define for it, such as AR_PP1 or AR_PP2. The child processes are multiprocess jobs and run in parallel.

  Each child process, such as AR_PP1, calls the AR_PREDICT2 Application Engine process, which does the actual payment application. AR_PREDICT2 matches the payments, updates the application tables, and generates process instances before ending the process. Each child process has its own process instance number and set of temporary tables and matches payments independently from the other child processes.
