what is buffering and how does it apply to vsam files ?..

Answer / Sudershan Kumar

Buffering in VSAM refers to the technique of storing data temporarily in a buffer pool before writing it to the actual file. This helps improve performance by reducing the number of I/O operations required for large datasets. Buffering is applied to VSAM files by specifying the size and type of buffer pools during ALLOCATE or CHGBUF commands.
