Command Definitions A-B
ALTGROUP
Each capability is denoted by a two letter mnemonic, as follows:
Process Handling = PH
Extra Data Segments = DS
Multiple RINs = MR
Privileged Mode = PM
Interactive Access = IA
Batch Access = BA
Default is IA, BA except for the PUB group of the SYS account which has no
true default. It is assigned the maximum group capabilities when the
system is delivered and should not normally be changed.
filespace Disk storage limit, in sectors, for the permanent files of the group. A
group's filespace cannot be set to a value greater than the corresponding
limits currently defined for the group's account. Nor can a group's filespace
be set to a value less than the actual number of sectors in use in that
group. Default is unlimited file space.
cpu The limit on the total cumulative CPU-time, in seconds, for the group. This
limit is checked only when a job or session is initiated; the limit never
causes a job/session to abort. The maximum value allowed is 2,147,483,647
seconds. If the limit is exceeded, users with account manager capability
are warned when logging on; other users are denied access.
The CPU limit for a group cannot be set to a value greater than the
corresponding limit currently defined for the group's account. Default is
unlimited CPU-time. The counter may be set to zero with the RESETACCT
command.
connect The limit on the total cumulative session connect-time, in minutes, that
the group is allowed. This limit is checked at logon, and whenever the
session initiates a new process. The maximum value allowed is
2,147,483,647 minutes. If the limit is exceeded, users with account
manager capability are warned when logging on; other users are denied
access.
A group's connect limit cannot be set to a value greater than the
corresponding limit currently defined for the group's account. Default is
unlimited connect-time. The counter may be set to zero with the
RESETACCT command.
fileaccess The restriction on file access pertinent to this group. Default is
R,X:ANY;A,W,L,S:AL,GU for the public group (PUB); and R,A,W,L,X,S:GU
for all other groups, where R, L, A, W, and X specify modes of access by
types of users (ANY, AC, GU, AL, GL) as follows:
R = READ
L = LOCK
A = APPEND
W = WRITE
X = EXECUTE
S = SAVE
LOCK allows exclusive access. APPEND implicitly specifies LOCK. WRITE
implicitly specifies APPEND and LOCK.
