HP-UX Workload Manager User's Guide

Configuring WLM
Defining the PRM components (optional)
Chapter 5 165
init_group Is the name of the initial workload group for the user or
netgroup. This is the group login chooses when
launching the user’s login shell, and the group cron
chooses when scheduling jobs for that user.
For information on a user’s group placement when the
user belongs to multiple netgroups, see the Process
Resource Manager User’s Guide.
alt_groupX (Optional) Is the name of one of the alternate workload
groups for the user or netgroup. Alternate groups are
groups other than the initial group in which the user or
netgroup members are allowed to run processes.
NOTE A process may start in a workload group other than its assigned group
due to its inheriting the group of the process that started it. However,
WLM will eventually move the process to the workload group specified in
its user record.
When determining the workload group assignment for a process
identified by multiple records, WLM gives highest precedence to
assignments defined in process maps (or to assignments made using the
prmmove or prmrun commands). The precedence given to the various
records that define workload group placement is described in “How the
application manager affects workload group assignments” on page 459.
Assigning Unix groups to workload groups (optional)
When the number of users in an organization or enterprise is
substantial, users might be assigned to Unix groups to simplify
permissions assignments and other management tasks. You can assign
Unix groups to workload groups. Processes whose effective group ID
(GID) matches a Unix group record will run in the associated workload
group. WLM supports Unix group records only if PRM C.03.02 or later is
running on the system.
You can assign a Unix group to one workload group only; however,
multiple Unix groups can be assigned to the same workload group. If a
user should be given access to more than one workload group, it might be
simpler to use the user record instead of the Unix group record to assign
users to workload groups.
