8.99.4 Examples

Example 1:

Change the MAXRATES interval from the default value (or the last manually set interval value) to 60
minutes.

HHC00013I Herc command: 'maxrates 60'

HHC02204I maxrates set to 60 minutes

Example 2:

Display the maximum observed MIPS and I/O rates during the last interval.

HHC00013I Herc command: 'maxrates'

HHC02272I Highest observed MIPS and IO/s rates:

HHC02272I From Thu Apr 19 22:58:34 2012 to Fri Apr 20 22:58:34 2012

HHC02272I MIPS: 105.333858

HHC02272I IO/s: 3068

HHC02272I From Fri Apr 20 22:58:34 2012 to Fri Apr 20 23:06:38 2012

HHC02272I MIPS: 5.678100

HHC02272I IO/s: 54

HHC02272I Current interval is 1440 minutes

8.100 MEMLOCK (Lock Hercules memory)

8.100.1 Function

The MEMLOCK console command is used to lock Hercules memory in storage. It defines the locking
state of the allocated Hercules memory (page lock by host operating system). Given without argument
MEMLOCK displays the current setting. If Hercules memory is locked in storage it cannot be paged out
by the host operating system. This may result in some performance improvements.

This console command is available if Hercules is built with option “_HAVE_MLOCKALL”. Currently
MEMLOCK is only supported under Linux host operating systems.
