Updating the conﬁguration

To update your conﬁguration, simply change your conﬁguration ﬁle and

load it. You do not need to disable or reset PRM to make changes to your

PRM conﬁguration.

For small changes you can bring the conﬁguration ﬁle into a text editor

or a GUI, make the changes, save the ﬁle, and then load the

conﬁguration with prmconfig or a GUI.

If you are adding a large number of new users to the conﬁguration ﬁle,

you can use prmloadconf to add the users for you. For each user in the

password ﬁle not already speciﬁed in the conﬁguration ﬁle, prmloadconf

appends a PRM user record to the conﬁguration ﬁle. The added record

speciﬁes the user’s login name from the password ﬁle and the

placeholder (NONE) instead of a PRM group. After using prmloadconf,

you may want to modify the user’s initial group and add alternate

groups. After changing the conﬁguration ﬁle, you must still load the

conﬁguration using either prmconfig or a GUI.

When using prmloadconf, if the conﬁguration ﬁle already exists,

elements of the existing ﬁle are checked for suitability (such as the

presence of the user default group). Use the -f option to specify a

conﬁguration ﬁle other than /etc/prmconf.

If the new conﬁguration deletes a group, then all currently running

processes that were associated with that group are moved to the owner’s

initial group, and to the assigned groups for conﬁgured applications. If a

process owner does not have an initial group or its group does not exist in

the new conﬁguration, the process is moved to the user default group

OTHERS (PRMID 1). If the owner of a process running in a group that is

deleted is a root user, the process is moved to the system group. The

system group, PRM_SYS (PRMID 0), is automatically created by PRM,

and system processes run there by default.
