User Response: There are several actions you can
take to make more saved segment pages available for
the event partition, or to reduce the number of pages
required, or both.
Enter the QUERY MONITOR EVENT command to
display the number of pages reserved for configuration
records. Then do one or more of the following:
v If the number of pages reserved for event
configuration records is larger than required, use the
MONITOR EVENT CONFIG command to reduce that
number.
v Increase the size of the event partition by using the
PARTITION option (when you start event monitoring)
to specify a larger number at least as large as 8 plus
the number of pages reserved for event configuration
records, or use a larger saved segment if defaulting.
Reenter the command to start event monitoring.
HCP6555E The MONITOR EVENT START failed
because even with the largest possible
DCSS, the default partition size will not
be large enough. At least n pages are
currently needed.
Explanation: A MONITOR EVENT START or
MONITOR START command has been entered to start
event monitoring. No user is currently connected to
*MONITOR, so the saved segment to be used is not
known to monitor. However, even 50% of the largest
possible saved segment will not contain n pages, the
number of pages needed to contain those pages
currently reserved for configuration records and the
minimum number of pages (8) needed for event data
records.
System Action: The command is rejected.
User Response: Make more saved segment pages
available for the event partition or to reduce the number
of pages required, or both.
Enter the QUERY MONITOR EVENT command to
display the number of pages reserved for configuration
records.
Then do one or more of the following:
v If the number of pages reserved for event
configuration records is larger than required, use the
MONITOR EVENT CONFIG command to reduce that
number.
v Increase the size of the event partition by using the

to specify a larger number at least as large as 8 plus
the number of pages reserved for event configuration
records.
Reenter the command to start event monitoring.
HCP6555E HCP6556E
HCP6556E {Sample|Event} monitoring cannot start
because there are not enough pages
available in the DCSS dcssname. n
pages are available.
Explanation: A MONITOR START command has been
entered to start event and/or sample monitoring, and the
saved segment saved segment name previously
established as the monitor saved segment does not
have enough unused pages to start the requested type
of monitoring.
For sample monitoring, this means that the available
space, n pages, is not large enough to contain the
reserved number of pages for sample configuration
records plus at least 1 page for sample data records.
For event monitoring, this means that the available
space, n pages, is not large enough to contain the
number of pages specified for the event partition.
System Action: The command is rejected.
User Response: Enter QUERY NSS saved segment
name to determine the number of pages in the saved
segment being used by monitor.
If starting event monitoring has failed, you can do one
or more of the following:
v Reenter the MONITOR EVENT START command
with the PARTITION option specifying fewer than n
pages.
Note: The number of pages requested for the event
partition must be at least the number of pages
reserved for event configuration records plus
8. If not, use the MONITOR EVENT CONFIG
command to redefine the number of pages
reserved for event configuration records before
entering the command to start event
monitoring.
v In addition to, or instead of the above, you can
reduce the size of the sample area before starting
event monitoring by the following actions.
– Enter MONITOR SAMPLE STOP to stop sample
monitoring.
– Use the MONITOR SAMPLE CONFIG command
to redefine the number of pages reserved for
sample configuration records. The number must
not be greater than the size of the saved segment,
minus the desired number of pages in the event
partition, minus 1 page for sample data records.
– Restart sample monitoring (MONITOR SAMPLE
START command).
– Enter the MONITOR EVENT START command
with the PARTITION option specifying a value that
is not greater than the number of pages in the
saved segment, minus the minimum number of
pages in the sample area (the number of pages
reserved for sample configuration records, minus
1).
