Issue/Introduction

Is it possible to use an alias name instead of the full DSNAME in ZDMSPARM, SYSPAUTH, PARMAUTH, DMSSET jobs?

 

Resolution

An ALIAS can be used in PARMAUTH and DMSSET jobs, but not in ZDMSPARMS and SYSPAUTH.

Additional Information

In ZDMSPARM an ALIAS can't be used. The data set names specified in this member are simply compared with the data set name allocated to the PARMLIB DD. An ALIAS in this member will not be resolved to the true name. If we have the following ALIAS for example

ALIAS --------- DISK.PARMLIB
IN-CAT --- ICF.VMVXE54
HISTORY
RELEASE----------------2 CREATION--------2020.128
ENCRYPTIONDATA
DATA SET ENCRYPTION-----(NO)
ASSOCIATIONS
NONVSAM--hlq.DISK.CCUWPARM
***

and we have DISK.PARMLIB in ZDMSPARM, then we end up comparing "hlq.DISK.CCUWPARM", which is used in the JCL, with "DISK.PARMLIB" from ZDMSPARM which does not match.

In SYSPAUTH no data set name is used. Just the RESOURCE name for the security checks is specified.
