Setting the system date and time is fairly easy on solaris. Because you can easily set the time from the command line, you can set the time on a server remotely but you have to do it as superuser (root user).
date mmddhhmmyy
The date command takes the syntax mmddhhmmyy, or “month day hour minute year”. You have to be superuser to set the time.
Example:
# date 1201053112
Fri Dec 1 05:31:00 PST 2012
Starting up and shutting down the oracle listener is a routine task for a database administrator. However a Linux system 
administrator or programmer may end-up doing some basic DBA operations on development database. It is critical for non-DBAs to understand the basic database admin activities.
In this article, let us review how to start, stop, check status of an oracle listener using Oracle listener control utility LSNRCTL.
Before starting, stopping or restarting make sure to execute lsnrctl status command to check the oracle listener status as shown below. Apart from letting us know whether the listener is up or down, you can also find the following valuable information from the lsnrctl status command output.
If the Oracle listener is not running, you’ll get the following message.
lsnrctl status

If the Oracle listener is not running, start the listener as shown below. This will start all the listeners. If you want to start a specific listener, specify the listener name next to start. i.e lsnrctl start [listener-name]

ALOM System Controller enables you to remotely manage and administer a server.
It comes preinstalled on the machine, so as soon you plug in power cable, it works.
Yes, it uses server’s standby power, which enables you to remotely power off and on server (very useful when someone schedule power outage in remote office and you want gracefully to bring server down and after outage power it on). ALOM monitors hardware in the server, like CPU, RAM, Power supply, etc, and much more like Voltage and status of alarms. Of course, all this exercise assumes you configured ALOM’s network parameters.
Try to have dedicated management subnet for this. If you access ALOM and stay idle for 1 minute, it will switch to serial console. Or you can type console and reach serial console of remote system from your cube or home living room.
sc> console To go back to ALOM type #. (pound and dot)
ALOM Commands :
showplatform [-v]
consolehistory [-v] [boot | run]
showusers [-g]
showsc [-v]
showlogs [-v]
