In addition to action taken by the data class ACS, it is possible for a data class to be assigned via JCL (DATACLAS operand on the DD statement), the corresponding operands of dynamic allocation, the DATACLAS operand on the TSO ALLOCATE command, and the DATACLAS operand of the IDCAMS ALLOCATE/DEFINE command. (See DFSMSdfp Storage Administration.)
It is also possible for the RACF resource owner of a dataset (specified in the RESOWNER field of the DFP operand on the ADDSD command) to have a default data class (specified in the DATACLASS field of the DFP operand of the ADDUSER/ADDGROUP command). SMS will use this value if ACSDEFAULTS is set to YES in the PARMLIB member IGDSMSxx. :>: -----Original Message----- :>: From: IBM Mainframe Discussion List [mailto:[email protected]] On :>: Behalf Of John Dawes :>: Sent: Monday, February 18, 2013 9:24 AM :>: To: [email protected] :>: Subject: Re: SMS QUESTION - DATACLAS NOT DEFINED IN SMS ACS :>: :>: Greg, :>: :>: Sorry I should have worded my question more clearly.
