How does zVM store data in it's spool file? More specifically,
in VSE/Power, a decision had to be made as to the block size of the
Power data file (spool file). If you made the block size small, you
utilized space better for small entries but you'd get an increase in
I/O. If you used large block sizes, you reduced I/O but lost space.
For example, if you submitted JCL, say 3 or 4 cards, they would occupy a
whole block. A small report or items in the punch queue worked the same
way. (I haven't worked with VSE in a loonnngg time so this may have
changed.)
I was wondering how zVM stored data in it's spool file. I don't recall
specifying a block size specifically for the spool size.
Thanks,
