How PRM manages applications

Chapter 266

The precedence of PRM record types—from highest to lowest—is:

1. Compartment record

2. Application record

3. User record

4. Unix group record

The PRM application manager goes through the following steps to

determine in which PRM group to place a process.

1. Manually moved processes

Leave manually moved processes (processes moved using prmrun or

prmmove) in their current PRM groups.

2. Compartment records

Move a process running in a secure compartment that is mapped to a

PRM group using a compartment record to the assigned PRM group.

3. Application records

If the ﬁle ID of the process matches the ﬁle ID for the full pathname

of any application listed in an application record in the current

conﬁguration, make the following checks:

a. If the process name is an exact match of an alternate name given

in the application record, move the application to the PRM group

assigned in the record.

b. If the process name matches any of the alternate names speciﬁed

by pattern (regular expression) in application records, then:

• If it matches only one alternate name, move it to the PRM

group speciﬁed in that record.

• If it matches multiple alternate names speciﬁed by pattern,

move the process to the PRM group speciﬁed in the “ﬁrst”

matching record.

The “ﬁrst” matching record is determined by sorting the

alternate names speciﬁed by pattern in lexicographical

(ASCII dictionary) order.

c. Move the process to the PRM group speciﬁed in the application

record that has no alternate name.
