Virtual storage access method (VSAM) Question:
How do you decide on optimum values for CI, FREESPACE etc?
Answer:
CI size should be based on record length, type of processing. Usually CI is 4K. If record length is larger(>1K), chose 6K or 8K.
FREESPACE should be large if more number of insertions are envisaged. Usual values are (20 20) when heavy updates are expected. CI size can be calculated.
