update w/o reboot
Hi,

The apar instructions is to reboot on the ibm site. Is there's a way to update apar w/o reboot? I think I heard something before that it's possible.

Thanks in any idea you will type...

As long as you don't want to use the changed feature that comes with such an APAR which requires a reboot you don't have to reboot. I am not aware of any os update that would force you to reboot immediately. However if you want to use the updated kernel you will have to reboot.

Mind also that if you don't reboot the patched kernel on disk is not the same as the kernel in memory. Hence some things won't work. E.g it might be impossible to do any io or vm tuning till you reboot and you might get strange/silly error messages.
