There are several method to know this information.
The easiest is talk with your storage admin that(I'm sure) has a lot of utility.
But if you want retrieve the same information by yourself you can write a Clist or a Rexx and with a few row of code you can do it fast.
The only prerequisite that you must to have is a list or radical(root) of your dataset.
Do you need samples? |

Ok, try with this rexx and this jcl:
Rexx(to be stored in a library FB and LRECL=80):
| Code: |
/*% NOCOMMENT REXX */
/* PROGRAMMA: xxxxxxxx */
/* AUTORE : MGIndaco */
/* ENV. : BATCH */
ADDRESS TSO
'Profile noprefix'
TrkTotal = 0
Say '-----------------------------------------'
Say '- Begin ---------------------------------'
Say '-----------------------------------------'
"execio * diskr FILELIST (stem FileList. finis"
say ' Files List : ',
!!' SysAlloc :',
!!' SysUnits :',
!!' SysTrksCyl :',
!!' Tracks :'
say ' -------------------------------------------',
!!'+-------------',
!!'+-------------',
!!'+-------------',
!!'+-------------'
Do iList = 1 To FileList.0
FileList.iList = Strip(FileList.iList,T)
Info = ListDSI("'"FileList.iList"'")
Select
When Strip(SysUnits) = 'CYLINDER' Then Do
Tracks = SysAlloc * SysTrksCyl
End
When Strip(SysUnits) = 'TRACK' Then Do
Tracks = SysAlloc
End
End
say ' '!!Substr(FileList.iList,1,44),
Substr(SysAlloc,1,13),
Substr(SysUnits,1,13),
Substr(SysTrksCyl,1,13),
Substr(Tracks,1,13)
TrkTotal = TrkTotal + Tracks
End
Say ' ------------------------'
Say ' Tracks used : ' TrkTotal
Say ' ------------------------'
Say '-----------------------------------------'
Say '- End -----------------------------------'
Say '-----------------------------------------'
Exit Rc |
This is the JOB:
| Code: |
//STEP010X EXEC PGM=IKJEFT01,PARM='name of rexx pgm'
//SYSEXEC DD DISP=SHR,DSN=library where pgm is stored
//SYSTSPRT DD SYSOUT=B
//FILELIST DD *
File1 without quotes
File2
File3
File4
//SYSPRINT DD SYSOUT=B
//SYSTSIN DD DUMMY |
P.S.= If you copy/paste use "Renum;Unnum" after to avoid error. |
