Note: The number of pages requested for the
event partition must be not less than the
number of pages reserved for event
configuration records plus 8. If
necessary, 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 Restart sample monitoring
HCP6558E The MONITOR EVENT START failed
because the default partition size
cannot be allocated. Only n pages are
available.
Explanation: A MONITOR EVENT START command
has been entered to start event monitoring. The
PARTITION option was not specified, so monitor
attempted to allocate 50% of the saved segment to the
event partition. However, sample monitoring has already
been started, and the number of pages currently
reserved for sample recording is greater than 50% of
the saved segment.
System Action: The command is rejected.
User Response: Either reduce the number of pages
reserved for sample recording, or specify an event
partition size that is less than n pages.
To reduce the number of pages reserved for sample
recording:
v Use the QUERY NSS command to determine the
number of pages in the first type SC page range of
the saved segment.
v Use the QUERY MONITOR SAMPLE command to
check the number of pages currently reserved for
sample configuration records.
If larger than necessary, do the following.
– Enter MONITOR SAMPLE STOP to stop sample
monitoring.
– Use the MONITOR SAMPLE CONFIG command
to reserve a smaller number of pages for sample
configuration records.
– Restart sample monitoring (MONITOR SAMPLE
START command).
v If the number of pages reserved for sample
configuration records plus 1 is not greater than half
the size of the saved segment, you can start event
monitoring with the partition defaulted to 50% of the
saved segment.
If it is greater, you must specify a partition size no
larger than the size of the saved segment, minus the
number of pages reserved for sample configuration
records, minus 1.
HCP6559E The MONITOR EVENT START failed
because even with the largest possible
DCSS, the default partition size could
not be allocated. At most, n pages are
available.
Explanation: A MONITOR EVENT START or
MONITOR START command has been entered to start
event monitoring. The PARTITION option was not
specified, so monitor will attempt to allocate 50% of the
saved segment to the event partition. No user is
currently connected to *MONITOR, so the saved
segment to be used is not currently known to monitor.
However, sample monitoring has already been started,
and the number of pages currently reserved for sample
recording requires more than 50% of even the largest
possible saved segment.
System Action: The command is rejected.
User Response: Either reduce the number of pages
reserved for sample recording, or specify an event
partition size that is less than n pages.
To reduce the number of pages reserved for sample
recording:
v Use the DEFSEG command to determine the
maximum number of pages in a saved segment.
v Use the QUERY MONITOR SAMPLE command to
check the number of pages currently reserved for
sample configuration records.
If larger than necessary, do the following.
– Enter MONITOR SAMPLE STOP to stop sample
monitoring.
– Use the MONITOR SAMPLE CONFIG command
to reserve a smaller number of pages for sample
configuration records.
– Restart sample monitoring (MONITOR SAMPLE
START command).
v If the number of pages reserved for sample
configuration records plus 1 is not greater than half of
the maximum size of a saved segment, you can start
event monitoring with the partition defaulted to 50%
of the saved segment.
If it is greater, you must specify a partition size no
larger than the maximum size of a saved segment,
minus the number of pages reserved for sample
configuration records, minus 1.
HCP6577E Invalid ALET - alet.
HCP6558E HCP6577E
Explanation: The ALET is invalid because:
v The ALET alet is longer than eight hexadecimal
characters
v Or the ALET contains non-hexadecimal characters. If
alet is a valid command operand, the value after the
ALET operand is missing.
System Action: The command is not executed;
system operation continues.
