3 Licensing Restrictions

This section covers the following topics:

- Oracle Database XE CPU Limitations

- Oracle Database XE Installation and Execution Restrictions

- Oracle Database XE User Data Limitations

- Oracle Database XE RAM Limitation

- HTTPS Support

3.1 Oracle Database XE CPU Limitations

If Oracle Database XE is installed on a computer with more than one CPU (including dual-core CPUs), then it will consume, at most, processing resources equivalent to one CPU. For example, on a computer with two CPUs, if two Oracle database clients try to simultaneously execute CPU-intensive queries, then Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition will use both CPUs to efficiently process the queries. However, with Oracle Database XE, the Oracle database will process the queries at the rate of a single CPU even if concurrent processing on two CPUs would be faster. To use the full processing resources of your computer, upgrade to Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition.

3.2 Oracle Database XE Installation and Execution Restrictions

Only one installation of Oracle Database XE can be performed on a single computer. This does not affect any existing installation or new installations of Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition. In addition, users can run only one instance of the Oracle Database XE database on each individual computer. To run more than one Oracle Database server instance or install more than one copy of the database software, upgrade to Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition.

3.3 Oracle Database XE User Data Limitations

The maximum amount of user data in an Oracle Database XE database cannot exceed 11 gigabytes. If the user data grows beyond this limit, then an ORA-12592 error will appear. To use more than 11 gigabytes of user data, upgrade to Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition.

3.4 Oracle Database XE RAM Limitation

The maximum amount of RAM that an Oracle Database XE database uses cannot exceed 1 gigabyte, even if more is available. Table 1, "Oracle Database XE Requirements" provides the minimum and recommended RAM that you should use. The exact amount of RAM that Oracle Database XE uses is computed automatically using Automatic Memory Management.

To use more than 1 gigabyte of RAM, upgrade to Oracle Database 11g Standard Edition, Oracle Database 11g Standard Edition One, or Oracle Database 11g Enterprise Edition.

For more information about managing memory, refer to Oracle Database Express Edition 2 Day DBA.

3.5 HTTPS Support

HTTPS is not supported natively with the HTTP listener built into Oracle Database XE. If you want HTTPS support, use an alternative Web listener, such as Apache, that does provide HTTPS support, and provide proxies for the URLs provided by Oracle Database XE.

For information about managing security in Oracle Database XE, refer to Oracle Database Express Edition 2 Day DBA.

4 Installing Oracle Database XE

This section covers the following topics:

- Procedure for Installing Oracle Database XE

- Performing a Silent Installation

- Setting the Oracle Database XE Environment Variables

- Compiling the Oracle ODBC Driver Demos

- Making Oracle Database XE Available to Remote Clients

4.1 Procedure for Installing Oracle Database XE

Before attempting to install Oracle Database XE 11.2 uninstall any existing Oracle Database XE or database with the SID XE from the target system.

To install Oracle Database XE:

1. Log on to your computer with root permissions.

2. Go to the following Web site:
http://www.oracle.com/technetwork/database/express-edition/downloads/index.html

3. Click Free Download and follow the instructions to select and download the Linux version of Oracle Database XE.

4. Run the Oracle Database XE executable oracle-xe-11.2.0-1.0.x86_64.rpm to install Oracle Database XE.

# rpm -ivh downloads/oracle-xe-11.2.0-1.0.x86_64.rpm

The installation displays a status of its progress.

5. When prompted, run the following command:

# /etc/init.d/oracle-xe configure

6. Enter the following configuration information:

- A valid HTTP port for the Oracle Application Express (the default is 8080)

- A valid port for the Oracle database listener (the default is 1521)

- A password for the SYS and SYSTEM administrative user accounts

- Confirm password for SYS and SYSTEM administrative user accounts

- Whether you want the database to start automatically when the computer starts (next reboot)

This completes configuration. The database starts during the boot process.

Note:
The password for the INTERNAL and ADMIN Oracle Application Express user accounts is initially the same as the SYS and SYSTEM administrative user accounts.

To start the database manually, run this command as root user:

# /etc/init.d/oracle-xe start

To stop the database manually, run the following command as root user:

# /etc/init.d/oracle-xe stop

Note:
You can find the database creation logs in $ORACLE_HOME/config/log/*.

4.2 Performing a Silent Installation

The response file xe.rsp is shipped along with the Oracle Database XE executable .rpm file.

To perform a silent installation:

1. After downloading the installation executable (described under "Procedure for Installing Oracle Database XE"), prepare the response file xe.rsp that contains settings for the following values:

- ORACLE_LISTENER_PORT: A valid listener numeric port value, so that you can connect to Oracle Database XE

- ORACLE_HTTP_PORT: A valid HTTP port numeric value for Oracle Application Express

- ORACLE_PASSWORD: A password value for the SYS and SYSTEM administrative user accounts

- ORACLE_CONFIRM_PASSWORD: The SYS and SYSTEM password value again, to confirm it

- ORACLE_DBENABLE: Yes (y) or no (n), to specify whether you want to start Oracle Database XE automatically when the computer starts

The default values are populated for ORACLE_LISTENER_PORT, ORACLE_HTTP_PORT, and ORACLE_DBENABLE in the response file.

2. Create a wrapper shell script to perform the silent installation.
It should contain commands similar to the following:

#!/bin/bash

rpm -ivh  /downloads/oracle-xe-11.2.0-1.0.x86_64 > /xe_logs/XEsilentinstall.log

/etc/init.d/oracle-xe configure responseFIle=<location of xe.rsp> >> /xe_logs/XEsilentinstall.log

3. Run the wrapper script as the root user.
For details of the installation, see the XEsilentinstall.log file.

After you complete the silent installation, set the Oracle Database XE environment variables, which is described in Section 4.3, "Setting the Oracle Database XE Environment Variables".

Note:
You can find the database creation logs in $ORACLE_HOME/config/log/*.

4.3 Setting the Oracle Database XE Environment Variables

After you have installed and configured Oracle Database XE, users must set their environment before they use Oracle Database XE. They do not need to log on with root permissions to do so. Oracle Database XE provides a script that sets the necessary environment variables.

Follow these steps:

1. Go to the following directory:
/u01/app/oracle/product/11.2.0/xe/bin

2. Look for the following scripts:

- oracle_env.csh (for C or tcsh shell)

- oracle_env.sh (for Bourne, Bash, or Korn shell)

3. Run the appropriate script for your shell. For example:

- Bourne, Bash, or Korn shell:

$ . ./oracle_env.sh

- C or tcsh shell:

% source oracle_env.csh

You may also want edit your login or profile files so that these environment variables are set properly each time you log in or open a new shell.

For Bourne, Bash, or Korn shell, enter the following line into the .bash_profile (to log in) or .bashrc file (to open a new shell):

. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh

For C or tcsh shell, enter the following line into the .login file (to log in) or .cshrc file (to open a new shell):

source /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.csh

4.4 Making Oracle Database XE Available to Remote Clients

After you install Oracle Database XE, the Get Started With Oracle Database 11g Express Edition home page is only available from the local server, not remotely.

Security Note:
With remote HTTP access to Oracle Database XE, all information exchanged between the browser and the database is in clear text—that is, unencrypted—including database user names and passwords. If this is cause for concern, do not enable remote HTTP connection to the database.

To use the SQL Command Line, follow these steps:

1. Start SQL*Plus and log in as SYSTEM:

$ sqlplus system
Enter password: SYSTEM_password

Or, if you are logging in remotely:

$ sqlplus system@xe_server_host_name
Enter password: SYSTEM_password

2. At the SQL prompt, enter the following command:

SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);

4.5 Compiling the Oracle ODBC Driver Demos

If you plan to compile and run the Oracle ODBC Driver demos, then follow these steps:

1. If you do not have unixODBC DriverManager installed, then download it from the following Web site:
http://www.unixodbc.org/

2. Set the ODBCDM_HOME environment variable to point to the directory where you installed DriverManager.

3. Run the following make file to compile the Oracle ODBC Driver demos:

make -f demo_xe.mk buildodbcdemo ODBCDM_HOME=DriverManager_location

5 Starting Oracle Database XE

After you have installed Oracle Database XE, the database is up and running and you can begin using it right away, as follows:

1. If the database is currently stopped, start it as follows: click the Main menu (on Gnome) or the Applications menu (on KDE), then Oracle Database 11g Express Edition, and then click Start Database.

2. Go to the Main menu (on Gnome) or the Applications menu (on KDE), then Oracle Database 11g Express Edition, and then click Run SQL Command Line. Connect to the database using the user name SYSTEM, and supply the password that you created during configuration.

3. To begin learning about Oracle Database XE, use the OracleDatabase XE Documentation.
To access the Oracle Database XE Documentation, from the Main menu (on Gnome) or the Applications menu (on KDE), select Oracle Database 11g Express Edition, then Get Help, and then click Read Documentation.

Note:
To use Oracle Database XE, your user id must be a member of Linux group dba.

6 Deinstalling Oracle Database XE

When you deinstall Oracle Database XE, all components, including data files, the database, and the software, are removed. If you want to save your data files but remove the Oracle Database XE software and database, then first export the data by using one of the methods described in Oracle Database Express Edition 2 Day DBA before you deinstall.

Because the deinstallation process removes all files from the directory in which Oracle Database XE is installed, back up any files from the directory (if needed) before you deinstall.

This section covers the following topic:

- Deinstalling the Oracle Database XE Software

6.1 Deinstalling the Oracle Database XE Software

Follow these steps:

1. Log on with root privileges.

2. Run the following command to deinstall Oracle Database XE:

# rpm -e oracle-xe

7 Importing and Exporting Data between 10.2 XE and 11.2 XE

To import and export data between 10.2 XE and 11.2 XE, perform the following steps:

1. Copy the gen_inst.sql file from the upgrade directory of 11.2 XE shiphome to your local directory.

2. Connect to 10.2 XE database as SYS user and run gen_inst.sql. This will generate install.sql, gen_apps.sql and other .sql files. The files will be generated in the folder containing gen_inst.sql.

SQL> @<local_dir>/gen_inst.sql

where local_dir is the local directory where gen_inst.sql is copied

Note:
Do not copy the gen_inst.sql file into the 10.2 XE home directory if you plan to install XE 11.2 on the same system. All generated files get deleted if XE 10.2 is uninstalled.

3. To export the data from 10.2 XE database, perform the following steps:

1. Connect to 10.2 XE database as SYS user.

2. Create a dump folder dump_folder on the local file system.

3. Create directory object DUMP_DIR with READ and WRITE privilege to SYSTEM user.

SQL> CREATE DIRECTORY DUMP_DIR AS '/<dump_folder>';
SQL>GRANT read, write ON DIRECTORY DUMP_DIR TO system;

4. Export data from 10.2 XE database to the dump folder.

expdp system/system_password full=Y
EXCLUDE=SCHEMA:\"LIKE \'APEX_%\'\",SCHEMA:\"LIKE \'FLOWS_%\'\"
directory=DUMP_DIR dumpfile=DB10G.dmp logfile=expdpDB10G.log
expdp system/system_password TABLES=FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$
directory=DUMP_DIR dumpfile=DB10G2.dmp logfile=expdpDB10G2.log

4. Deinstall 10.2 XE if installation of 11.2 XE is planned on the same system.

5. Install 11.2 XE database. For more information see Section 4, "Installing Oracle Database XE".

6. To import data to the 11.2 XE database, perform the following steps:

1. Connect to 11.2 XE database as SYS user.

2. Create directory object DUMP_DIR with READ and WRITE privilege to SYSTEM user.

SQL> CREATE DIRECTORY DUMP_DIR AS '/<dump_folder>';
SQL>GRANT read, write ON DIRECTORY DUMP_DIR TO system;

3. Import data to 11.2 XE database from the dump folder.

impdp  system/system_password full=Y directory=DUMP_DIR
dumpfile=DB10G.dmp logfile=expdpDB10G1.log
impdp  system/system_password directory=DUMP_DIR
TABLE_EXISTS_ACTION=APPEND  TABLES=FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ dumpfile=DB10G2.dmp logfile=expdpDB10G1b.log

7. Connect to 11.2 XE database as SYS user and run the script install.sql, which was generated in Step 2. This will trigger the execution of ws.sql, gen._apps.sql, and other .sql files.

- The database is created using Unicode(AL32UTF8) character set, which is suitable for global data in any language.

- Japanese, Brazilian Portuguese, and Simplified Chinese language message files are installed in ORACLE_HOME.

- The Oracle Application Express user interface and database error messages are available in English, Japanese, Brazilian Portuguese, and Simplified Chinese.

"Globalization Support: Configuring Locale and Character Sets with the NLS_LANG Parameter" provides additional character and language information.

10 Globalization Support: Configuring Locale and Character Sets with the NLS_LANG Parameter

This section explains how to configure globalization settings for Oracle Database XE. It covers the following topics:

- About the NLS_LANG Parameter

- Default Values for NLS_LANG

- Supported Character Sets

- Charmap and Oracle Character Set

10.1 About the NLS_LANG Parameter

Oracle provides globalization support that enables users to interact with a database in their preferred locale and character set settings. Setting the NLS_LANG environment variable specifies locale behavior for Oracle software. It sets the language and territory used by the client application and the database server. It also sets the character set for entering and displaying data by a client program, such as SQL*Plus.

The NLS_LANG parameter uses the following format:

NLS_LANG = LANGUAGE_TERRITORY.CHARACTER_SET

This format is explained in the following table:

Parameter

Description

LANGUAGE

Specifies the language for displaying product messages, day names, and month names in SQL.
Oracle Database Globalization Support Guide provides more information about languages.

TERRITORY

Specifies the cultural-specific conventions for date, number, time, and monetary formatting.
Oracle Database Globalization Support Guide provides more information about territory conventions.

CHARACTER_SET

Specifies the encoding used by the client application, which is usually the character set of the source data being processed, and the character set used in displaying the output.
"Supported Character Sets" provides a list of supported character sets.

Oracle Database Globalization Support Guide provides information about the NLS_LANG parameter and Globalization Support initialization parameters.

10.2 Default Values for NLS_LANG
