Process Move Recommendations
This section of the report (Example 3-13) contains recommendations, based on the GPA
analysis of the node, for improving the performance of the system. It tells what
processes could be moved to other CPUs on the node to achieve a more balanced
load distribution and better utilization of existing memory. You implement the moves
that are appropriate for your particular situation.
Example 3-13. Process Move Recommendations
Process Move Recommendations Primary Issue: MEMORY SHORTAGE
1 CPU: 0 2 SHORT MEMORY BY: 612 PHYSICAL PAGES.
MOVE 0, 71 $ZVPT $SYSTEM SYSTEM PATHMON TO CPU 2 5.30% BSY PGS 431 P
MOVE 0, 73 $Z194 $SYSTEM SYSTEM PATHTCP2 TO CPU 3 3.74% BSY PGS 170 P
As Example 3-13 shows, the report gives: (1) the identification number of each memory-
short or over utilized CPU and (2) the number of pages of memory shortage or, in the
case of an over utilized CPU, the percentage of overutilization (before any process
moves but after the GPA primary path moves for the CPU).
(1) CPU: The identification number of each memory-short or over utilized
CPU.
(2) SHORT MEMORY BY: The number of pages of memory shortage or, in
the case of an over utilized CPU, the percentage of overutilization
(before any process moves but after the GPA primary path moves for
the CPU).
For each processor, the report lists:
(3) The process identification (CPU number, PIN, and process name).
(4) The program file (volume, subvolume, and filename).
(5) The CPU to which the process is to be moved.
(6) The percentage busy time for the process. (This figure may be adjusted
by the appropriate factor if the CPU to which the process is moved is
of a different type than the original one.)
(7) Number of pages in memory occupied by the process.
(8) Whether the move refers to a process pair (designated by P or B) or a
single process (designated by *).
