kmtune vs lsattr

Thanks for your info. I have used lsattr -E -l sys0 command to look at the tunable kernel parameters. I cannot find any mention of minperm/maxperm nor minfree/maxfree in the output. Can these parameters only be accessed via kmtune? The box has live applications on it, so if invoking kmtune will affect the server in anyway, it won't be used.

The full output of lsattr -E -l sys0 gives:

# lsattr -E -l sys0
keylock normal State of system keylock at boot time False
maxbuf 20 Maximum number of pages in block I/O BUFFER CACHE True
maxmbuf 0 Maximum Kbytes of real memory allowed for MBUFS True
maxuproc 256 Maximum number of PROCESSES allowed per user True
autorestart false Automatically REBOOT system after a crash True
iostat true Continuously maintain DISK I/O history True
realmem 2097152 Amount of usable physical memory in Kbytes False
conslogin enable System Console Login False
fwversion IBM,M2P00279 Firmware version and revision levels False
maxpout 0 HIGH water mark for pending write I/Os per file True
minpout 0 LOW water mark for pending write I/Os per file True
fullcore false Enable full CORE dump True
pre430core false Use pre-430 style CORE dump True
rtasversion 1 Open Firmware RTAS version False
modelname IBM,7026-H80 Machine name False
systemid IBM,01654960A Hardware system identifier False
boottype disk N/A False
SW_dist_intr false Enable SW distribution of interrupts True
cpuguard disable CPU Guard True
#

Are there any parameters here that need their values changing?

Thanks,

xkbignoreextension

XkbIgnoreExtension(3)						   XKB FUNCTIONS					     XkbIgnoreExtension(3)

NAME

       XkbIgnoreExtension -  Prevents core X library keyboard functions from using the X Keyboard Extension

SYNOPSIS

       Bool XkbIgnoreExtension (Bool *ignore);

ARGUMENTS

       ignore True means ignore the extension

DESCRIPTION

       If  a server supports the Xkb extension, the X library normally implements preXkb keyboard functions using the Xkb keyboard description and
       state. The server Xkb keyboard state may differ from the preXkb keyboard state. This difference does not affect most clients, but there are
       exceptions. To allow these clients to work properly, you may instruct the extension not to use Xkb functionality.

       Call  XkbIgnoreExtension to prevent core X library keyboard functions from using the X Keyboard Extension. You must call XkbIgnoreExtension
       before you open a server connection; Xkb does not provide a way to enable or disable use of the extension once a connection is established.

       XkbIgnoreExtension tells the X library whether to use the X Keyboard Extension on any subsequently opened X display connections. If  ignore
       is  True, the library does not initialize the Xkb extension when it opens a new display. This forces the X server to use compatibility mode
       and communicate with the client using only core protocol requests and events. If ignore is False, the library treats  subsequent  calls	to
       XOpenDisplay  normally  and  uses Xkb extension requests, events, and state. Do not explicitly use Xkb on a connection for which it is dis-
       abled.  XkbIgnoreExtension returns False if it was unable to apply the ignore request.

RETURN VALUES

       True	      The XkbIgnoreExtension returns True if

       False	      The XkbIgnoreExtension function returns False if it was unable to apply the ignore request.
