This SOM can change CM capacity allocated to MPBs
with dierent workloads.
Mode 908 = ON: The
dierence in CM allocation
capacity among MPBs with dierent workload is
large.
Mode 908 = OFF (default): The dierence in CM
allocation capacity among MPBs with dierent
workload is small (existing operation) .
Notes:
1. If a CLPR is used by only some MPBs among all
the installed MPBs, set this SOM to ON for the
CLPR to increase CM capacity allocated to the
MPBs that use the CLPR.
Example:
(a) A CLPR only for UR JNLG.
(b) A conguration where MPBs and CLPRs are
separately used for Open and Mainframe
systems.
2. Since CM capacity allocated to MPBs with low
load is small, the performance is aected by a
sudden increase in load.
3. SOM 908 cannot be used with SOM 933. When
SOM 933 is set to ON, the function of SOM 908
is canceled even though SOM 908 is ON.
4. This SOM is eective for a CLPR. Therefore,
when setting this SOM to ON/OFF, select target
"LPRXX (XX=00 to 31)". For example, even when
CLPR0 is dened (any of CLPR1 to 31 are not
dened), select “LPR00” rst and then set this
SOM to ON/OFF.
