VSAM Interview Question:

What is the meaning of each of the values in SHAREOPTS(2 3)?

Submitted by: Administrator

Value of 2 for cross region means that the file can be processed simultaneously by multiple users provided only one of them is an updater. Value of 3 for cross system means that any number of jobs can process the file for input or output (VSAM does nothing to ensure integrity).
