What is Batch Processing Integration?

Batch processing integration in CICS involves integrating CICS systems with batch processing environments. It includes CICS batch processing concepts, batch job integration, batch scheduling and management, and batch monitoring and reporting for comprehensive batch processing solutions.

Batch Processing Integration Explained Simply

Think of batch processing integration like having a factory assembly line that works together with a warehouse. Just like a factory processes large batches of products efficiently, batch processing handles large amounts of data efficiently. The integration means your CICS system can work together with batch processing systems to handle big jobs.

In CICS, batch processing integration means your CICS system can process large amounts of data in batches - like processing thousands of customer records at once, or generating reports for thousands of accounts. Instead of processing each record one by one (which would be slow), batch processing handles them all together efficiently.
