What is the difference between BLKSIZE and LRECL?

Answer Posted / guest

LRECL is the length of ur record file.
Blksize is the length of the block in which records are
stored.It varies in case of fixed length records and
variable length records.
fixed length records-It is a multiple of lrecl.
e.g. suppose u have blksize =800 & lrecl=80.It means that
there are 10 records each of size 80.
variable length records-It is the length of longest record
in the block + 8 (bcoz. here lrecl=length of longest record
+4 & blksize=lrecl+4).
