210 The Virtualization Cookbook for Red Hat Enterprise Linux 5.2

In this example, it starts at x3300 and ends at x6FFF (this is a PAGE boundary). You also

need to issue q nss all map to determine where the new MONDCSS can be located with no

overlap.

First, delete the old MONDCSS by issuing:

PURGE NSS NAME MONDCSS

If any users are currently connected to the MONDCSS, you need to log off those users. You

can determine who is connected by issuing Q MONITOR.

Next, create a new MONDCSS:

CP DEFSEG MONDCSS 03300-09FFF SC RSTD

Save the new MONDCSS:

CP SAVESEG MONDCSS

Then you can restart PERFKIT. If you receive any messages from the PERFKIT that the

MONDCSS SAMPLE CONFIG size is too small, you have to enlarge it as previously

explained. The same would apply to the MONITOR EVENT CONFIG SIZE, if you receive a

PERFKIT message pertaining to that.

If you continue to receive MONDCSS SIZE TOO SMALL messages, you will need to restart

this process over again, increasing the total size of the MONDCSS segment.

RESTART the PERFKIT and monitor the startup for at least 2 monitor interval timeframes to

ensure things are working and there are no error type messages.

Important: Check carefully to make sure that the new MONDCSS does not overlap any

other NSS. If it does, PERKIT may not be able to use it.

One way to test whether the MONDCSS segment can be loaded is to issue SEGMENT

LOAD MONDCSS before you start PERFKIT. If it returns any error (for example,

DMSDCS343E), there may be an overlap and you have to redefine the MONDCSS

location.

Often, you can simply raise the ending location of the current MONDCSS to solve this

problem.

Recommendation: There is a relationship between the PERFSVM virtual machine

storage size and the MONDCSS segment size, as described here.

򐂰 The PERFSVM virtual machine storage size should be of ample size to contain the

entire MONDCSS segment, plus some CMS pointer tables.

򐂰 Or, the MONDCSS must be located outside the size of the PERFSVM virtual machine

storage size (the preferred solution).
