The SDB parameter does generate the optimum blocksize. It only controls whether the generated blocksize can exceed 32760. Refer to the first part of the EXEC statement section in the IEBGENER chapter of the DFSMSdfp Utilities manual.
Note that for LARGE, the output CAN be greater than 32760 but the manual gives no clue as to when it actually will be. :>: -----Original Message----- :>: From: IBM Mainframe Discussion List [mailto:[email protected]] On :>: Behalf Of Paul Gilmartin :>: Sent: Saturday, April 12, 2014 7:06 AM :>: To: [email protected] :>: Subject: IEBGENER PARM='SDB=?????' :>: :>: What value of IEBGENER PARM='SDB=?????' is intended to allow SDB :>: to operate and select an optimum BLKSIZE for SYSUT2 regardless of :>: the BLKSIZE of SYSUT1?
