Hi,
Can somebody help me.
//OUTPUT DD DSN=XXXX.YY.ABCDE.XYZ.D200507,
// DISP=(NEW,CATLG,DELETE),AVGREC=K,
// SPACE=(TRK,(200,150),RLSE),UNIT=(SYSDA,10),
// DCB=(RECFM=VB,LRECL=7077,DSORG=PS)
Suppose I have the output file above. How do I compute for the suitable space allocation if I am expecting 190K records to be processed.
We are afraid that we will be getting abends because of the volume of records that we are expecting to be processed. |

Primary allocation 200 tracks (not contigious) and 150 secondary extend if necessary spreaded out over 10 dasd-units. Primary allocation could eat up all extends. No volumes assigned. No blocksize.
Find out the number of cylinders on the sysda units. Multiply your recordlength with 190K and divide that number by one cylinder capicity.

Going by our shop standards, you would specify
| Code: |
// SPACE=(7077,(187,37),RLSE),AVGREC=K,DATACLAS=XXXX
