Hi,

I have to design a Specification document which involves in creating new files which retrieves some rows from db2 tables.

To do so i need to calculate the file space attributes as no. of cylinders it occupies. I am not much familiar with the relation between the blocks and cylinders.

Can any one help me.

Cheers
Ashwin

HI ashwin,
IF YOU KNOW PARA FROM DCB i.e. LREC AND BLKSIZE WHILE CREATING NEW DATASET WHERE SUPPOSE WE GIVE LRECL=80 AND BLKSIZE = 800 THEN ONE BLOCK WILL CONTAIN 10 PAGES THAT IS THE RELATION BETWEEN LOGICAL RECORD LENGTH AND BLOCK SIZE
