NOTE: Note that each memory record must be preceded by the #! characters. These lines are
not treated as comments.
A white paper, titled HP Process Resource Manager memory resource groups: Memory calculation,
on the web at http://h20338.www2.hp.com/hpux11i/downloads/5983-1676EN.pdf presents
a case study of setting memory allocations for PRM groups.
Use the following syntax to specify a memory record:
#!PRM_MEM:{PRMID|GROUP}:SHARES:[MAX]:::[[IMPORT]:[EXPORT]:]
where
#!PRM_MEM Indicates the start of a memory record.
PRMID | GROUP Is a PRM group ID or group name that corresponds to an existing group.
When specifying parents in a group hierarchy, use their names.
SHARES Specifies the group’s guaranteed proportion of available memory. Shares
are integer values ranging from one to MAXINT.
MAX (Optional) Specifies a cap (upper bound) for memory consumption for any
non-HIER PRM group. This integer value represents a percentage and must
be greater than or equal to the percentage determined by the group’s
number of memory shares. There is no requirement that the max values
total 100%.
IMPORT, EXPORT Allow a PRM group to borrow or lend memory resources. Leave both fields
blank to allow unrestricted borrowing and lending. (Leaving the fields blank
enables the proportional overachievement feature.) Assign both fields a
value of 0 to isolate a memory-critical group to ensure it gets exactly the
memory you give it.
You cannot set EXPORT to 0 for the OTHERS group.
NOTE: If you add memory records to the PRM configuration file, your configuration file must not
contain a PRM_SYS (PRMID 0) group. If the group is already present, delete it.
Consider the following example memory records:
# PRM memory records
#!PRM_MEM:1:10:25:::
#!PRM_MEM:databases:30::::
#!PRM_MEM:databases/inventory:15::::
#!PRM_MEM:3:15::::
#!PRM_MEM:4:55::::
#!PRM_MEM:5:5:15:::
#!PRM_MEM:6:20::::0:0:
The example shows:
• A memory record for PRMID 1 (group OTHERS), which specifies 10 memory shares. The
memory cap is 25%.
• The parent group databases starts a hierarchy and is granted 30 memory shares to be
divided by its child groups.
• A memory record for the databases/inventory group. Rather than using its name, we
could have used its PRMID, which is 2, as we see from the example in the section “Group/CPU
record syntax” (page 55). This record specifies 15 memory shares. No memory cap is set.
• A memory record for PRMID 3. We could have used the group’s name, databases/order,
in place of the PRMID. This record specifies 15 memory shares. No memory cap is set.
• A memory record for PRMID 4, which grants 55 memory shares. No memory cap is set.
