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

iostat true Continuously maintain DISK I/O history True
realmem 2097152 Amount of usable physical memory in Kbytes 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,
