I like to know, how to convert cylinders to megabytes
and Track to Megabyte conversion? |
Quote: |
Here, I have coded RLSE parameter for DEAA11A.SWARS but still it shows 100% used.
How CYL,(2500,500) is shown as Tracks Used: 60000 Cyls: 4000 |
Code: |
XXSORTOUT DD DSN=DEAA11A.SWARS(+1), XX DISP=(NEW,CATLG,CATLG), XX SPACE=(CYL,(2500,500),RLSE),VOL=(,,,10), XX UNIT=SYSDA, XX MGMTCLAS=MC0030, XX DCB=(PSDSCB,DSORG=PS,RECFM=VB,LRECL=2004) |
Code: |
XXSORTOUT DD DSN=DEAA11A.SWARS(+1), XX DISP=(NEW,CATLG,CATLG), XX SPACE=(CYL,(2500,500),RLSE),VOL=(,,,10), XX RECFM=VB,LRECL=2004 |

RECFM and LRECL are parameters in their own right and no longer need to be coded as sub parameters of the DCB field. |
Quote: |
BLKSIZE would be LRECL+4 which would waste a lot of DASD space. |
Quote: |
do you mean the DCB parameters are not required |
Code: |
1 Cylinder = 55,996 * 15 = 839,940 bytes. so 1000 cylinders = 839,940 * 1000 1 Megabyte = 1,048,576 (2 to the 20th power) bytes. 1000 cylinders = (839,940 * 1000 ) / 1,048,576 = 801.029 MB 1 terabyte = 2 to the 40th power or approximately a thousand billion bytes (that is, a thousand gigabytes). 1000 cylinders = (839,940 * 1000 ) / (1,048,576 * 1,048,576 ) = .000763 Terabytes |
