5 October 2015
Objectives
This specification explains how to install Oracle 11g Release 2 on Windows 7 system,
how to start and stop a database, and how to use SQL*Plus client.
Installing the system
To install the system, perform the following steps.
(0)
Copy a file OracleXE112_Win32.zip from CSCI315 folder located
on your CSCI315 DVD to the Desktop on your computer.
(1)
Unzip
a
file
OracleXE112_Win32.zip
to
OracleXE112_Win32 on the Desktop of your computer.
(2)
Open a folder OracleXE112_Win32. Open a folder DISK1.
(3)
Start setup.exe. The system should start InstallShield Wizard. It takes a
minute or two while the system prepares to install. Wait until the system
opens a windows “Oracle Database 11g Express Edition – Install
Wizard”.
(4)
When the preparations are finished, click at Next> button in a window
“Oracle Database 11g Express Edition – Install Wizard”.
(5)
Pick “I accept the terms in the license agreement” and click at Next>
button.
(6)
Choose a destination location (you may accept a destination location
proposed by Oracle Installer) and click at Next> button.
(7)
Type in a password for both SYSTEM and SYS users. A password is up to
you. It should be a string of characters that must start from a letter and it is a
combination of letters and digits. When both passwords for SYSTEM and
SYS users are typed in, click at Next> button.
(8)
Read information provided in a summary and if everything is all right, click
at Install button. The system should open a window Oracle Database 11g
Express Edition – Install Wizard and start the installation. The installation
a
folder
procedure will run for few minutes. Wait until the system displays a message
“Install Shield Wizard Complete”.
(9)
Click at Finish button.
(10)
Shutdown and restart an operating system.
(11)
The system should display an icon "Get Started with Oracle Database
11g Express Edition". Click at the icon. The system starts a default Web
browser and opens HTML document with information about the parameters
and the present state of "Oracle Database XE 11.2". Browse the document.
At the moment you do not need to perform any of the actions described in the
document. Close Web browser and perform the actions described in the next
section of this document.
Stopping/Starting the system
Oracle 11g XE server should be up and running now.
(0)
To shutdown Oracle XE server, navigate through START->All Programs>Oracle Database 11g Express Edition->Stop Database. Leftclick at
Stop Database. The system opens Stop Database command window and
stops OracleServiceXE service. You should get the messages:
The OracleServiceXE service is stopping ..... The
OracleServiceXE service was stopped successfully.
To stop a listener execute the following command in a command window:
lsnrctl stop
The system should display a message:
The command completed successfully.
Close a command window.
(1)
To startup the system, navigate through START->All Programs->Oracle
Database 11g Express Edition->Start Database. Leftclick Start
Database. The system opens Start Database command window. The
system should display the following messages:
The
The
The
The
OracleXETNSListener service is starting.
OracleXETNSListener was started successfully.
OracleServiceXE service is starting.....
OracleServiceXE was started successfully.
Close a command window.
Starting SQL*Plus client (method 1)
To start SQL*Plus client and to connect as a user SYSTEM perform the following steps.
(0)
Find a folder XE in CSCI315 folder on your CSCI315 DVD. Copy a folder
XE into drive C:.
(1)
Navigate through START->All Programs->Oracle Database 10g
Express Edition->Run SQL Command Line. Rightclick (!)Run SQL
Command Line.
(2)
Select Properties.
(3)
Type:
C:\XE
into “Start in” field. In this way you determine a location of your SQL scripts
each time SQL*Plus client is started. Leftclik OK button. Note, that you do
not have to perform this step (3) when running SQL*Plus client the next time.
(4)
Navigate through START->All Programs->Oracle Database 10g
Express Edition->Run SQL Command Line. Leftclick Run SQL
Command Line.
At SQL> prompt type:
connect system
to connect as a user SYSTEM.
(5)
Type a password of a user SYSTEM. It is a password you entered in a step (7)
of Installation procedure. The system should reply with a message:
Connected.
and with SQL> prompt in the next line.
(6)
We would like to run SQL script that lists the names of files and tablespaces
an Oracle database consists of. To do so type:
@sf
at SQL> prompt and press Enter key. The system should list the names of
tablespaces, the paths and names of files the tablespaces consist of, internal
file identifiers, and size of files in bytes. At the moment a database consists of
four tablespaces: USERS, SYSAUX, UNDO, SYSTEM. You may have to
expand a Command line window to get a nice and clear output.
(7)
To disconnect from SQL*Plus type:
exit
Comment: To connect as user anyuser you may also execute:
connect anyuser
instead of connect system. A connect command of SQL*Plus allows you to
connect as another user without closing SQL*Plus client. It is explained below how to
create a new user account, e.g. anyuser.
Starting SQL*Plus client (method 2)
To start SQL*Plus client perform the following steps.
(0)
Navigate through START->All Programs->Accessories->Command
Prompt, leftclick Command Prompt.
(1)
Use cd command to move to a directory that contains your SQL scripts, i.e to
move to a directory XE execute a command:
cd c:\XE
(2)
Execute a command:
sqlplus /nolog
A command sqlplus /nolog starts SQL*Plus client and does not
connect a client as any user.
(3)
Type at SQL> prompt:
connect system
to connect as a user SYSTEM.
(4)
Type a password of a user SYSTEM. It is a password you entered in a step (7)
of Installation procedure. The system should reply with a message:
Connected.
and with SQL> prompt in the next line.
(5)
We would like to run SQL script that lists the names of files and tablespaces
an Oracle database consists of. To do so type:
@sf
at SQL> prompt and press Enter key. The system should list the names of
tablespaces, the paths and names of files the tablespaces consist of, internal
file identifiers, and size of files in bytes. At the moment a database consists of
four tablespaces: USERS, SYSAUX, UNDO, SYSTEM. You may have to
expand a Command line window to get a nice and clear output.
(6)
To disconnect from SQL*Plus type:
exit
Next, close a Command line window.
Comment: To connect as user anyuser you may also execute:
connect anyuser
instead of connect system. A connect command of SQL*Plus allows you to
connect as another user without closing SQL*Plus client. It is explained below how to
create a new user account, e.g. anyuser.
Creating a new user
To create a new user, perform the following steps.
(0)
Start SQL*Plus client using either method 1 or method 2 explained above.
(1)
Connect as a user SYSTEM.
(2)
Assume, that we would like to create a new user QQQ with a password
PSSST. At SQL> prompt execute a command:
CREATE USER QQQ IDENTIFIED BY PSSST;
(3)
Next, we have to grant the functional privileges to the user. At SQL> prompt
execute a command:
GRANT RESOURCE,CONNECT TO QQQ;
(4)
To connect as a user QQQ execute at SQL> prompt:
connect QQQ
(5)
Type in a password (PSST).
(6)
We would like to run again SQL script that lists the names of files and
tablespaces an Oracle database consists of. To do so type: @sf at SQL>
prompt and press Enter key. The system should reply with a message:
SET ECHO OFF
FROM DBA_DATA_FILES
*
ERROR at line 5:
ORA-00942: table or view doest not exist
The error message above means that user QQQ has no rights to access a data
dictionary relational view DBA_DATA_FILES that contains information
about tablespaces and data files. At the moment, only the users SYSTEM and
SYS have the rights to access DBA_DATA_FILES. It is explained in the
laboratory classes how to grant to a user the data access rights and functional
access rights.
Dropping a user
To drop a user, perform the following steps.
(0)
If SQL*Plus client is not started then start SQL*Plus client using either
method 1 or method 2 explained above.
(1)
Connect as a user SYSTEM.
(2)
At SQL> prompt execute a command:
DROP USER QQQ CASCADE;
You can find more information about the management of the system in the
laboratory specifications.
What to do next ?
In the next step you have to create and to load data into a sample database. Open a file
CreatingSampleDB.pdf and follow the instructions written there.
