Most of our production HP boxes have been up for 300 days or so. We never reboot them just for the heck of it. I guess that the most common reason to reboot is to install a patch that requires a reboot. I would not agree with a monthly reboot policy.
And a symptom like "some slowness" is not a good reason to reboot. You need to examine the box and find out why it is slow. Note that application memory leaks can be resolved to restarting the application. (Ideally such an application should be fixed.) Do you have a reason to suspect a memory leak? How many page outs is vmstat reporting?
Sometimes a box is wierd and you can't locate the problem and as a last resort, you need to try a reboot. But that should rarely happen and you should have a fairly lengthy list of other stuff that you tried first.

I'm in process of creating oracle RAC using Solaris 10 in VirtualBox. I want to know how can I change the ownership of device e.g /dev/rdsk/c0t3d0s0 and keep it persistent during rebbots.
When I enter

SYSTEMD-TIMESYNCD.SERVICE(8) systemd-timesyncd.service SYSTEMD-TIMESYNCD.SERVICE(8)
NAME
systemd-timesyncd.service, systemd-timesyncd - Network Time Synchronization
SYNOPSIS
systemd-timesyncd.service
/lib/systemd/systemd-timesyncd
DESCRIPTION
systemd-timesyncd is a system service that may be used to synchronize the local system clock with a remote Network Time Protocol server. It
also saves the local time to disk every time the clock has been synchronized and uses this to possibly advance the system realtime clock on
subsequent reboots to ensure it monotonically advances even if the system lacks a battery-buffered RTC chip.
The systemd-timesyncd service specifically implements only SNTP. This minimalistic service will set the system clock for large offsets or
slowly adjust it for smaller deltas. More complex use cases are not covered by systemd-timesyncd.
The NTP servers contacted are determined from the global settings in timesyncd.conf(5), the per-link static settings in .network files, and
the per-link dynamic settings received over DHCP. See systemd.network(5) for more details.
timedatectl(1)'s set-ntp command may be used to enable and start, or disable and stop this service.
FILES
/var/lib/systemd/timesync/clock
This file contains the timestamp of the last successful synchronization.
