User and Group (Job)

Draft MDC Standard

Right Hand Pointer

7.1.3.5.4 Characteristic: User and User Group

^$Job( processid , expr1 V "UseR" ) = expr2
^$Job( processid , expr1 V "GROUP" ) = expr2

If and only if the process identified by processid is associated by the implementation with a user for security purposes, the value of the node "UseR" is an implementation-specific unambiguous identifier of the user owning the process.

If and only if the process identified by processid is associated by the implementation with a group of users for security purposes, the value of the node "GROUP" is an implementation-specific unambiguous identifier of a user group to which the user owning the process belongs.

These are write-once ssvns. At the time of process initiation as the result of execution of a Job command, the ssvn values associated with the initiating process are copied to the ssvns associated with the new process's processid unless overridden, in an implementation-specific manner, by the processparameters on the Job command's jobargument. If a node has a $Data value of 0 or 10, the process may create the node and assign an unconstrained value to it. When a node has a $Data value of 1 or 11, a value may not be assigned nor may the node be Killed; when a process attempts to do so an error occurs with ecode = "M96". At the termination of the process identified by processid, these ssvns become undefined.
