MAXDXIZE

[nagendra_3]

Hi,
Could you please let me know if changing the MAXDSIZE , kernal parameter requires a reboot.

We are using HP-UX 11.0

Tks,
Nag

Yes it does require a reboot. At 11.0 *ALL* kernel changes require the kernel to be rebuilt and system rebooted.

Any modificarions in kernel needes a reboot..

Since 11.0 has no dynamic tunables, a reboot would always be required. Moreover, even in 11.11, maxdsiz is not a dynamic tunable.

Hi,

maxdsiz is for 32bit applications and maxdsiz_64 is for 64bit applications. So, make sure you are changing the correct parameter.

Yes. You will need to reboot the box after the kernel compilation. You can use either SAM or the following steps to make changes.

#cp /stand/system /stand/system.date
#/usr/lbin/sysadm/system_prep -s /stand/system
#kmtune -s maxdsiz=the_new_value
#mk_kernel -o /stand/vmunix
#kmupdate
#shutdown -r now
