rmss command

rmss command in AIX

The rmss (Reduced Memory System Simulator) command is used to estimate the effects of reducing the amount of available memory on a system without having to physically remove memory.

Syntax

rmss [-s startmemsize] [-f finalmemsize] [-d deltamemsize]
[-n numiterations] [-o outputfile] command
rmss -c memsize
rmss -r
rmss -p

Examples of rmss

To display the current memory size, use the -p flag.

Example : Using rmss -p

r33n01:/ # rmss -p
Simulated memory size is 7168 Mb.

To change the memory size, use the -c flag.

Example : Using rmss -c

r33n01:/ # rmss -c 2048
Simulated memory size changed to 2048 Mb.
r33n01:/ # rmss -p
Simulated memory size is 2048 Mb.

To reset the memory back to the real size, use the -r flag.

Example : Using rmss -r

r33n01:/ # rmss -r
Simulated memory size is 7168 Mb.
