SPACE param doubt

Postby ranga_subham » Mon Oct 05, 2009 9:15 pm

Hi,

I am creating an output file -

//SYSUT01   DD DSN=OUT-FILE,
//             AVGREC=K,                                 
//             RECFM=VB,                                 
//             LRECL=31034,                             
//             BLKSIZE=31038,                               
//             VOL=(,,,10),                             
//             MGMTCLAS=MGMC01,                         
//             DISP=(NEW,CATLG,DELETE),                 
//             SPACE=(31034,(100,50),RLSE)               
//*                                                     


My doubt is whether I should refer LRECL or BLKSIZE in SPACE? I mean, Is SPACE=(31034,(100,50),RLSE) or SPACE=(31038,(100,50),RLSE) correct?

Thanks.

Hello,

Suggest you use TRK (or CYL) as the system will convert to TRKs anyway if blocklength is used. . . From the manual:
Primary Requests in Blocks

If you request space in terms of average block length, the system will compute and allocate the smallest number of tracks (or cylinders if ROUND is specified) to contain the number of blocks specified in primary-qty.
Hope this helps,
d.sch.
