B HP-UX command/system call support
Several HP-UX commands and system calls support PRM in assigning users and applications to the
proper PRM groups. Other commands have options that allow you to use PRM more efficiently. In
either case, this functionality is available only when PRM is configured. See the following tables
for information on these commands and system calls.
Table 32 lists HP-UX commands and system calls that support PRM groups. With HP-UX 11i v1
and later, most HP-UX commands and system calls support PRM.
Table 32 HP-UX commands/system calls that support PRM groups
Supports PRM as followsCommand/ system call
Places the scheduled job in the user’s initial PRM group. If the user does not have an initial
group, the job is placed in the user default group, OTHERS (PRMID 1).
at
Places the scheduled job in the user’s initial PRM group. If the user does not have an initial
group, the job is placed in the user default group, OTHERS (PRMID 1).
cron
Places the login process in the user’s initial PRM group. If the user does not have an initial
group, the login process is placed in the user default group, OTHERS (PRMID 1).
login
Process remains in its current PRM group.exec
Starts children processes in the parent’s PRM group.fork
Returns a process’s FSS PRMID.pstat
Table 33 describes HP-UX commands that have options for PRM.
Table 33 PRM options in HP-UX commands
DescriptionOptionCommand
Displays the PRMID of each process.-Pacctcom
Displays only processes belonging to the PRM group given by group, which
is specified by PRM group name or PRMID.
-Rgroupacctcom
Displays the PRMID and name of the invoking user’s initial group.-Pid
Adds a column named PRMID to the ps output that gives the PRM group name
associated with each process. If you also specify -l, you get the PRMID instead
of the PRM group name.
-P [-l]ps
Displays only the processes that belong to PRM groups specified in
group_list.
group_list must consist of PRMIDs or PRM group names. Groups must be
separated by commas; no spaces are allowed.
-Rgroup_listps
For more information on these commands, see their manpages.
