How application processes are assigned to workload
groups at start-up
Table F-2 describes what workload groups an application process is
started in based on how the application is started.
Table F-2 Group assignments at process start-up
Process initiated Process runs in workload group as follows
By user
By at
By cron
Upon login
Process runs in the user’s initial group. If the user does
not have an initial group, the process runs in the user
default group, OTHERS. (If the process has a
compartment record or an application record, or is
owned by a user or Unix group that has a record, or if it
is identified by a process map, it still starts in the
invoking user’s initial group. However, the application
manager will soon move the process to its assigned
group—with process maps taking precedence over
compartment records, compartment records over
application records, application records over user
records, and user records over Unix group records.
Record types and their precedence in workload group
assignments are discussed in Chapter 5, “Configuring
WLM,” on page 135.)
By prmrun {-g targetgrp | -i} Process runs in the workload group specified by
targetgrp or in the user’s initial group. The application
manager cannot move a process started in this manner
to another group. For more information on the PRM
utility prmrun, see Appendix E, “Useful PRM utilities,”
on page 445 and prmrun(1).
By prmrun application
(-g targetgrp is not specified)
Process runs in the application’s assigned workload
group. If the application does not have a group, an error
is returned.
