Starting / Shutdown Oracle Database in Unix
| Posted by watashii | Filed under Database, Unix
This simple guide to shows how to start /stop your Oracle database from Unix. You must have logon access to do this.
Step 1
Unix login as oracle (usually the user that installed the database)
Step 2
Make sure your environment variables are set, eg:
ORACLE_SID=MYDBSID
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/product/11.2.0/dbhome_1
LD_LIBRARY_PATH=/opt/oracle/product/11.2.0/dbhome_1/lib
PATH=/usr/bin:/usr/sbin:/usr/ucb:/usr/local:/usr/local/bin:/usr/local/sbin:/opt/oracle/product/11.2.0/dbhome_1/binStep 3 – Start DB Instance
On the Unix command line, run sqlplus with sysdba, and simply type startup in the prompt to start it up.
oracle@db-srv-01 % sqlplus '/ as sysdba'

Abort Windows Shutdown Using Shortcut
| Posted by watashii | Filed under Programming
This follows on from the previous post on how to force shutdown your Windows machine using a shortcut. This post shows how to cancel / stop Windows from shutting down after launching the shutdown command (eg by accident).
To create this shortcut, open Notepad, and add the following line of text, then save it with a .bat extension. You need to hit the shortcut quickly if you want to abort in time.
shutdown.exe -a
Where:
-a abort shutdown

Windows Vista – Change Sleep Button to Shutdown Button
| Posted by watashii | Filed under Software
Recently got my new computer system loaded with Windows Vista (Home Basic). The first annoyance I encountered was that the default power down on the Start Menu is the orange sleep mode button.
Having sleep mode allows quick resume of Windows without needing to reload Windows from scratch, as well as saving power – the benefits obvious.
But for the not-so occasional PC user, a shutdown button is more convenient. Here is how to swap it with red shutdown button.
- Goto [Start > Control Panel > Power Options]
- Click on the power plan in use, and select Advanced Power Settings
- Expand the + signs under Power Buttons and Lid, then Start Menu and Power Buttons
- Then in the dropdown box set it to the Shutdown setting
