Hi All!
This is more of a mainframe question than a COBOL one, but
nevertherless...
I am looking for a way to get information on dataset allocation (primary
and
secondary space) from a COBOL batch program. Basically what I am doing is
generating a JCL from this program, that will allocate a dataset with very
similar space allocation to a model dataset. To be correct on the PRI and
SEC allocation, I need the exact numbers - guessing them doesn't seem
right
:) This is a part of a larger backup manipulation process, so the amount
of
datasets is large.
Has anyone got a clue how to do it? I was already considering IDCAMS and
NAVIQUEST - the first one cannot be called from COBOL (at least not in a
programmer-friendly way), the second one is also batch driven. In both
cases
report analysis is difficult... I am sure some kind of a tool must exist
:(
BTW - no, I cannot use 'LIKE' in the space allocation parameters, as LIKE
has some serious limitations (i.e. it does not really allocate the same
space). "Unless you explicitly code the SPACE parameter for the new data
set, the system determines the space to be allocated for the new data set
by
adding up the space allocated in the first three extents of the model data
set. Therefore, the space allocated for the new data set will generally
not
match the space that was specified for the model data set." (IBM JCL
manual).
Please help! ;)
Thanks in advance,
Greg
