Does SDB make an adverse selection for loadlibs?
The issue is not block size selection but rather deterministic
recognition of the library as being a loadlib. Though common, DSORG=PO
and RECFM=U do not necessarily indicate a loadlib/polib. Therefore, the
system can't arbitrarily assume BLKSIZE=32760.
Has a suggestion
been made to IBM to ameliorate this? How much worse, by what
metric, is SDB's default (half track?) than 32760?
Non-sequitur. SDB does not choose 1/2 track blocking when RECFM=U.
My suggestion is to enhance SMS data classes to provide block size
information. If absent, SDB will be used. That way a user/task/program
can specify something like DATACLAS=LOADLIB to assign "shop standard"
attributes for load and program object libraries -- including block size
-- when they are created.
