SUBMIT adds a character only if the job text does not contain JOB
statement. IMHO submitting jobs without JOB statement is "quick and
DIRTY" method. Very dirty. It can be easily changed to allow 8-char
userids (add 1 charecter OR change eight character with random one).
Of course, requiring that job names begin with the user ID is the only
way to almost guarantee that job names are unique.
Of course it's not. One can imagine other naming conventions.
But even nowadays
is there anything to prevent my submitting a job not with the TSO SUBMIT
command (e.g. via FTP or by writing directly to INTRDR) that has your
user ID as a prefix?
Fortunately there is JESJOBS class which protects jobnames. You can
easily set up the rule "everything is allowed with exception to
reserverd names". No need to prefix jobnames with userid.
Is there anything except the good conscience of the
admin to prevent creating two user IDs where the second is the first
with a single character appended?
Naming convention, you can call it good conscience ;-)
Last, but not least: does anyone remember that userid can begin with
numeric? A user name 1234567 is legal one. Obviously TSO segment for
such userid is still big problem.
Simply because of DSN prefixing, or are there other concerns?
Yes. Some irony missed. ;-)
