Verification is the process of analyzing the code loaded into CA. The verification process demands a lot of CPU power. COBOL Analyzer is designed to use a single CPU core for the main application, but each Queue Processor can run on a separate CPU core. The Queue Processors can even run on multiple computers to help with the verification database loading. There are two ways of initiating the verification process. The first is the online tool (COBOL Analyzer) and the second is through the Batch Refresh Process (BRP).
