z/OS V1R6.0 DFSMS Access Method Services for Catalogs

ALLOCATEYou cannot use the REUSE parameter to reallocate a file from a disposition ofOLD to a disposition of SHR. However, you can first free the file with OLD,then reallocate it with SHR.ROUNDAllocates space equal to one or more cylinders. Use this only when yourequest space in units of blocks. This parameter corresponds to the ROUNDparameter in the SPACE parameter in JCL.SECMODEL(profile-name[,GENERIC])Names an existing RACF profile to copy to the discrete profile. UseSECMODEL when you want a different RACF data set profile from the defaultprofile selected by RACF, or when there is no default profile. The model profilecan be a:v RACF model profilev RACF discrete data set profilev RACF generic data set profileUse GENERIC to state the profile name as a generic data set profile.The system copies this information from the RACF data set profile to thediscrete data set profile of the new data set:vvvvvvvvvOWNER indicates the user or group assigned as the owner of the data setprofile.ID is the access list of users or groups that are authorized to access the dataset.UACC gives universal access authority that is associated with the data set.AUDIT|GLOBALAUDIT selects which access attempts are logged.ERASE indicates that the data set when it is deleted (scratched).LEVEL is the installation-defined level indicator.DATA is installation-defined information.WARNING indicates that an unauthorized access causes RACF to issue awarning message, but allows access to the data set.SECLEVEL is the name of an installation-defined security level.||||||||||||Exception: You can use the SECMODEL parameter to allocate bothSMS-managed and non-SMS managed data sets. If SMS is notactive, however, the system checks the syntax and then ignores theSECMODEL parameter.For more information about RACF, see z/OS Security Server RACF CommandLanguage Reference.SPACE(quantity[,increment])Allocates the amount of space for a new data set. If you omit this parameter,the system uses the IBM-supplied default value of SPACE(4,24) AVBLOCK(8192). However, your installation might have changed the default. For moreinformation about default space, see z/OS MVS Programming: AuthorizedAssembler Services Guide.To have the system determine the amount of space, include the AVGRECparameter in place of BLOCK, AVBLOCK, CYLINDERS, and TRACKS. Tosupply your own space value, define one of the following: BLOCK(value),BLKSIZE(value), AVBLOCK(value), CYLINDERS, or TRACKS. The amount ofspace requested is determined as follows:vBLOCK(value) or BLKSIZE(value): The BLOCK or BLKSIZE parameter’s valueis multiplied by the SPACE parameter’s quantity.Chapter 4. ALLOCATE 45
