Kernel parameters wont update

Luis Fernando Costa — Thu, 30 Jan 2003 13:40:54 GMT

Hi, all.
I updated some kernel parameters with SAM and rebooted (several times) my 9000/800 B.11.11 system, but kmtune -d still reports planned values (pending values):
Parameter Current Dyn Planned
==============================
maxdsiz 268435456 - 990056448
maxdsiz_64bit 1073741824 - 4294967296
maxfiles 500 - 1048
msgmnb 16384 Y 65535
msgseg 2048 - 32767
msgssz 8 - 32
msgtql 40 - 2046
nfile 2609 - 8192
nflocks 200 - 800
ninode 1538 - 8192
semmni 70 - 520
semmns 500 - 1024
semmnu 30 - 256
semume 10 - 100
shmmni 200 - 256
These are recommended for Sap Web App server 6.10 (64bits).
What is wrong ?

after updating the following steps are rquired.

/usr/lbin/sysadmin/system_prep -s system
mk_kernel -s system
kmpudate

reboot

sam can do this pretty easily too.

Allow me to post a complete procedure.

Don't point both posts please.

If you want to back up the system files. Its kind of late for that though.
# cp /stand/system /stand/system.$DATE
# cd /stand/build

# /usr/lbin/sysadm/system_prep -s /stand/build/system

# /usr/sbin/mk_kernel -s ./system"
# mv /stand/system /stand/system.prev"
# mv /stand/vmunix /stand/vmunix.prev"
# mv /stand/dlkm /stand/dlkm.vmunix.prev"
# mv /stand/build/system /stand/system"

Now you want to process the command:
# kmupdate /stand/build/vmunix_test"

cd /
shutdown -ry now

This will do you better than my earlier, incomplete post.

You'll need some space in /stand of course.
