Mainframe Hardware

Mainframe hardware consists of:

• Central Processing Unit (CPU): The brain of the mainframe, responsible for executing instructions.
• Memory: Mainframes have a large amount of memory, which is used to store data and programs.
• Storage: Mainframes use various types of storage devices, such as disk drives and tape drives.
• Input/Output Devices: Mainframes use various input/output devices, such as terminals, printers, and network interfaces.

2. VSAM (Virtual Storage Access Method)

VSAM is a non-negotiable topic for any mainframe interview. Muthu’s Part 2 breaks down:

• VSAM Cluster Types: KSDS, ESDS, RRDS, and LDS explained with real-world use cases.
• Alternate Indexes (AIX): Building paths to access VSAM files by non-primary keys.
• IDCAMS Commands: Essential utilities like DEFINE CLUSTER, REPRO, LISTCAT, and ALTER.
• Performance Tuning: Understanding CI/CA splits and how to prevent them.
