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
Re: SMS QUESTION - ACTUAL SPACE NOT ALLOCATED
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.

Re: SMS QUESTION - ACTUAL SPACE NOT ALLOCATED - ANSWER FOUND.
I found the answer to my question. In the SMS base config the Default device geometry is set up for 3380 instead of 3390 : Default Device Geometry Bytes/track . . . . . : 47476 Tracks/cylinder . . . : 15 This is causing the allocation to be reduced. To bypass the problem I am using UNIT=3390 instead of UNIT=SYSALLDA. Problem solved. Thanks.

Ted, Thanks. Our e-mails crossed each other. Yes, it is set to 47476 tracks as you had suggested. Thanks for your help.

I tried *really* to reproduce your problem but could not succeed in it. I even RTFM everything about that guarantee space, but of course it is *guaranteed* that I did not find anything. ;-D We are not using SYSALLDA, rather we use SYSDA with the type of device we're using the most. These days SYSDA means 3390. Now, it is 20:00 and it is guaranteed that I'm now going home. :-D Groete / Greetings Elardus Engelbrecht -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
