This sounds like the track size "problem". There were a lot of shops that implemented a default track size of 47476 (3380) rather than 56664 (3390). This ends up, after DADSM is finished with the allocation, with your dataset 80% of the request size.
Check with your. Storage Admins. (I forget where the size is specified) This crops up about once a year, even though it was identified over 20 years ago. - Ted MacNEIL eamacn...@yahoo.ca Twitter: @TedMacNEIL -----Original Message----- From: willie bunter <williebun...@yahoo.com> Sender: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> Date: Thu, 3 Oct 2013 07:48:05 To: <IBM-MAIN@LISTSERV.UA.EDU> Reply-To: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> Subject: SMS QUESTION - ACTUAL SPACE NOT ALLOCATED Good Day All, I am trying to allocate a dsn using PGM=IEFBR14 to create a dsn which of 25 cylinders. The dsn is SMS managed and it has GUASPACE as the Storage Class. The DC & MC are null. The dsn is allocated on the volume as requested however the space allocated is 20 instead of 25. I was able to allocated the space of 25 cylinders when I coded UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01. Could anybody tell me where my error is? Below is my jcl (which is run from a proc) //* //ALLOC EXEC PGM=IEFBR14 //A01065 DD &A01.DSN=&DSNIN..A01065,DISP=(,CATLG), // UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01 //IXX065 DD &IXX.DSN=&DSNIN..IXX065,DISP=(,CATLG), // UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01 //* Below is the inquiry on the dsn: Command ===> More: + Data Set Name . . . . : HEST.INTS.DATACOM.A01065 General Data Current Allocation Management class . . : **None** Allocated cylinders : 25 Storage class . . . : GUASPACE Allocated extents . : 1 Volume serial . . . : PROM01 Device type . . . . : 3390 Data class . . . . . : **None** Organization . . . : PS Current Utilization Record format . . . : F Used cylinders . . : 25 Record length . . . : 4096 Used extents . . . : 1 Block size . . . . : 4096 1st extent cylinders: 25 Secondary cylinders : 0 Dates Data set name type : Creation date . . . : 2013/09/27 SMS Compressible. . : NO Referenced date . . : 2013/10/03 Expiration date . . : ***None*** ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
