i) Difference between ps, esds,
ii) Difference between lrecl, blksize among PS, PDS issues?
i.e in jcl at dcb
Answer Posted / tanmay
(i)Ps stands for Physical sequential data set and ESDS is a
VSAM data set defined as Entry sequenced data set.In ESDS
records are processed one at a time in the order which they
were loaded.
(ii)lrecl stands for logical record length and blocksize
will be the multiple of lrecl.Lrecl gives the actual length
of the record and block size tells what unit of bloch has
been assigned on the DASD for that record.In DCB of JCL the
diference between PS and PDS are that the PDS will contain
one extra quantity called "directory blocks" alongwith
primary and secondary quantity whereas Physical Sequential
(PS) will contain only the primary and secondary quantity.
