SQL*Plus Client
First of all start SQL*Plus - see this page for details: Starting SQL*Plus
It will then present you with a log on screen similar to the following figure:
Fill in the following, note the format of the username carefully:
| User-name: | This is your student number, preceded by OPS$ and followed by @ora19c |
| E.g., if your username is 0912345, then type in: OPS$0912345@ora19c | |
| Password: | When you registered for Oracle, you will have been given a password. Type this in when prompted. |
| Note, the password will not be echoed on the screen, nor any asterisks shown. |
Do note that the password is case sensitive, but the user-name is not. Generally the initial password given starts with a capital letter. You can change this once you have logged in.
If you have logged in successfully you will be presented with the SQL> prompt:
Easy Connect String
If you find the @ora19c returns with
ORA-12154: TNS:could not resolve the connect identifier specified
Then when prompted for a username in SQL*Plus, type in:
yourOracleUsername/yourOraclePassword@ora-srv.wlv.ac.uk:1521/catdb.wlv.ac.uk
This must be entered as one line at the Enter user-name: prompt. Replace yourOracleUsername and yourOraclePassword with your own details.
SQL*Plus Command Line
The prompt: SQL> means the system is waiting for you to enter a command.
There are two types of command that you may enter:
• SQL commands. For manipulating data in the database. Each SQL command is terminated by a semi-colon, which will be seen later.
• Control commands. For formatting results and editing. The semi-colon is optional for these commands.
Changing Your Password
It is advisable to change your initial password to something else. To do this, once you have logged in, type:
password
It will ask for your old password first, before you can set a new one.
If you forget your new password and the system locks you out after several attempts, re-run the registration program and it will reset it back to the original password:
Please note: we can not access any updates to your password once you change it!
