Where do I find these?
There are two interfaces. One is the /proc/sys directory, and the
other
is sysctl. If you want to set something with sysctl, the easy way is
to
add a line in sysctl.conf (for example: vm.overcommit_memory=2) and
then
run sysctl -p to process the config file again.
Have just been through a few man pages.
Temporarily, the command sysctl vm.overcommit_memory=2 would do the job?
By itself, probably not.
What does the value '2' signify?
0 = heuristic overcommit
1 = always overcommit (until completely out of RAM + swap)
2 = overcommit (swap + (vm.overcommit_ratio * RAM))
What do sysrq-m and sysrq-t do? I haven't found them yet.
alt+sysrq+m prints memory statistics
alt+sysrq+t prints thread state information
Oh, currently vm.overcommit_memory=0 and kernel.sysrq=0.
You'll need to set kernel.sysrq=1 for keyboard sysrq input to be
honored. If you set vm.overcommit_memory=2, then vm.overcommit_ratio
will be honored.
