Mainframe utilities are software tools designed to perform specific tasks on mainframe computers. These utilities are essential for managing, maintaining, and optimizing mainframe systems. They are commonly used for tasks such as data management (copying, sorting, and merging datasets), system monitoring, performance tuning, backup and recovery, security administration, and job scheduling. Some examples include IBM's DFSORT for sorting and merging, IDCAMS for VSAM file management, and various utilities for system debugging and diagnostics. These utilities help to streamline mainframe operations, improve system efficiency, and ensure data integrity.
