Configuring PRM
Chapter 7 113
Controlling memory use
You can define private memory shares and caps for existing PRM groups
as well as allocate shared memory as discussed in the following sections:
• “Adding/modifying private memory shares/caps” on page 118
• “Adding/modifying shared memory allocations” on page 119
• “Removing private memory shares” on page 120
• “Removing shared memory allocations” on page 121
• “Isolating private memory for a group” on page 122
Memory record syntax
This section explains the syntax of memory records. PRM can control
allocation of both private and shared memory. The PRM configuration
file has separate record types for allocating memory, based on whether
the memory is private or shared. The syntax for each of these records is
discussed below.
NOTE Do not perform online cell operations, using parolrad or any other
interface, when PRM is managing memory. For more information, see the
WARNINGS section in the prmconfig(1) manpage.
Private memory Private memory records define real memory shares
and caps. They also allow you to isolate the memory of a group.
Memory records are optional. However, if you use PRM memory
management, you must have one memory record that corresponds to
each group/CPU record. A memory record corresponds to a group/CPU
record when the PRMIDs or group names match.
NOTE Note that each memory record must be preceded by the #! characters.
