I am running the tzupdater for Java from HP and it errors out because
of the maxfiles limit. HP said to change both of those parameters to
'4096'.

I know I can do:

kmtune -s maxfiles=4096
kmtune -s maxfiles_lim=4096
kmtune -u

That will update those parameters. What I have found is if those two
parameters are dynamic or whether I will have to rebuild the kernel
and reboot or just reboot after the change or no reboot necessary
because they are dynamic values.

I am not quite sure what you are trying to say in the paragraph above
- are there some missing "not"'s in there? Whether a given tunable is
dynamic depends on the OS release - later OS releases have a greater
percentage of dynamic tunables. I was under the impression that the
list one can get from kmtune/kctune had some indication as to whether
or not a rebuild/reboot was required.

It has been a while since I've messed with those things, but you may
also want to check the process's ulimits.

Probably my English wasn't that good... : )

maxfiles_lim is dynamic...so I changed that and it fixed my problem.
