During data set allocation processing, DFSMS requests the external security package to derive the RESOWNER of the specified data set name. If the data set is defined to CA Top Secret and the ownership record for that data set has been assigned a specific ACID as the RESOWNER, then this ACID is returned to DFSMS. If there is no RESOWNER assigned to a defined data set, or if the data set is not owned, CA Top Secret determines if the High Level Qualifier matches a User or Control ACID. If the High Level Qualifier is a valid ACID, this ACID is returned as the RESOWNER. In all other instances, the currently signed on ACID will be returned as the RESOWNER.
The RESOWNER attribute can be added to a data set, at the same time ownership of that data set is established. For example:
TSS ADDTO(deptacid) DSNAME(PAY.)
RESOWNER(smsacid)
If a data set is already owned and you want to assign a RESOWNER to that data set, you must determine the owner of the data set and the exact prefix of the data set that is owned. This can be accomplished with the TSS WHOOWNS command function. If you are attempting to assign a RESOWNER to data set PAY.MASTER, then you must initially perform:
TSS WHOOWNS DSNAME(PAY.MASTER)
A response indicates that PAYDEPT owns DSNAME(PAY.). To assign or change a RESOWNER of smsacid to data set PAY.MASTER, enter:
TSS ADDTO(paydept) DSNAME(PAY.)
RESOWNER(smsacid)
To remove a RESOWNER of smsacid from data set PAY.MASTER, enter:
TSS ADDTO(paydept) DSNAME(PAY.)
RESOWNER()
Note: When removing a RESOWNER there is nothing specified within the parentheses.
