The Oracle Database software is available on installation media, or you can download it from the Oracle Technology Network Web site, or the Oracle Software Delivery Cloud portal. In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install the software. However, you can also use Oracle Universal Installer to complete silent mode installations, without using the GUI.
See Also:
Appendix A for information about silent mode installationsReview the information in Chapter 1, "Overview of Oracle Database Installation" and complete the tasks listed in Chapter 2, " Oracle Database Preinstallation Requirements".
If you must perform multiple installations of Oracle Database, you may want to use silent mode or response file mode. In response file mode, at each node, you run Oracle Universal Installer from the command line using a response file. The response file is a text file that contains the settings you typically enter in the Oracle Universal Installer GUI dialog boxes.

Appendix A for information about silent mode installationsReview the following guidelines before starting Oracle Universal Installer:
Using Oracle Universal Installer from an earlier Oracle release to install components from this release is no longer allowed.
Oracle Automatic Storage Management
In previous releases, Oracle Automatic Storage Management (Oracle ASM) was installed as part of the Oracle Database installation. With Oracle Database 11g Release 2 (11.2), Oracle ASM is part of an Oracle Grid Infrastructure installation, either for a cluster, or for a standalone server.
To upgrade an existing Oracle ASM installation, upgrade Oracle ASM by running an Oracle Grid Infrastructure upgrade. If you do not have Oracle ASM installed and you want to use Oracle ASM as your storage option, then you must complete an Oracle Grid Infrastructure installation before you start your Oracle Database installation.
See Also:
Chapter 3, "Oracle Grid Infrastructure" for information about Oracle Grid Infrastructure for a standalone serverIf Oracle Clusterware and Oracle RAC are installed on the system, Oracle Universal Installer displays the Specify Hardware Cluster Installation page. You must select the Local Installation option, unless you want to install Oracle RAC.
Oracle Database uses the database character set for:
Data stored in SQL character datatypes (CHAR, VARCHAR2, CLOB, and LONG).
Identifiers such as table names, column names, and PL/SQL variables.
Stored SQL and PL/SQL source code, including text literals embedded in this code.
After a database is created, changing its character set is usually very expensive in terms of time and resources. Such operations may require converting all character data by exporting the whole database and importing it back. Therefore, it is important that you carefully select the database character set at installation time.
Oracle recommends Unicode AL32UTF8 as the database character set. Unicode is the universal character set that supports most of the currently spoken languages of the world. It also supports many historical scripts (alphabets). Unicode is the native encoding of many technologies, including Java, XML, XHTML, ECMAScript, and LDAP. Unicode is ideally suited for databases supporting the Internet and the global economy.
Because AL32UTF8 is a multibyte character set, database operations on character data may be slightly slower when compared to single-byte database character sets, such as WE8MSWIN1252. Storage space requirements for text in most languages that use characters outside of the ASCII repertoire are higher in AL32UTF8 compared to legacy character sets supporting the language. The increase in storage space concerns only character data and only data that is not in English. The universality and flexibility of Unicode usually outweighs these additional costs.
Consider legacy character sets when compatibility, storage requirements, or performance of text processing is critical and the database supports only a single group of languages. The database character set to be selected in this case is the character set of most clients connecting to this database.
The default character set suggested or used by Oracle Universal Installer and Database Configuration Assistant in this release is based on the language configuration of the operating system.
For most languages, the default character set is one of the Microsoft Windows character sets, for example WE8MSWIN1252, even though the database is not installed on Windows. This results from the assumption that most clients connecting to the database run under the Microsoft Windows operating system. Because the database should be able to store all characters coming from the clients and Microsoft Windows character sets have a richer character repertoire than the corresponding ISO 8859 character sets, the Microsoft Windows character sets are usually the better choice. For example, the EE8MSWIN1250 character set supports the Euro currency symbol and various smart quote characters, while the corresponding EE8ISO8859P2 character set does not support them. Oracle Database converts the data between the database character set and the client character sets, which are declared by the NLS_LANG settings.
The list of database character sets that is presented to you for selection by Oracle Universal Installer contains only the recommended character sets. Even though Oracle Database supports many more character sets, they are either deprecated or they are binary subsets of another recommended character set. For example, WE8DEC is a deprecated character set and US7ASCII and WE8ISO8859P1 are both binary subsets of WE8MSWIN1252.
If, for compatibility reasons, you must create a database in one of the character sets that was not recommended, select the Advanced database configuration option. Database Configuration Assistant in the interactive mode gives you the opportunity to select any of the database character sets supported on Linux.
This section is optional and describes how to identify disk groups and determine the free disk space that they contain. You can store either database or recovery files in an existing Oracle ASM disk group that you created during the Oracle Grid Infrastructure installation.
Note:
The Oracle ASM instance that manages the existing disk group runs in the Oracle Grid Infrastructure home directory.To determine if an existing Oracle ASM disk group exists or to determine if there is sufficient disk space in a disk group, use the following procedure:
View the contents of the oratab file to determine if an Oracle ASM instance is configured on the system:
# more /etc/oratab
If an Oracle ASM instance is configured on the system, then the oratab file contains a line similar to the following:
+ASM:oracle_home_path:N
In this example, +ASM is the system identifier (SID) of the Oracle ASM instance and oracle_home_path is the Oracle home directory where Oracle ASM is installed. By convention, the SID for an Oracle ASM instance should be +ASM.
Open a shell prompt and temporarily set the ORACLE_SID and ORACLE_HOME environment variables to specify the appropriate values for the Oracle ASM instance to use.
For example, if the Oracle ASM SID is named +ASM and is located in the grid subdirectory of the ORACLE_BASE directory, then enter the following commands to create the required settings:
Bourne, Bash, or Korn shell:
$ ORACLE_SID=+ASM $ export ORACLE_SID $ ORACLE_HOME=/u01/app/oracle/product/11.2.0/grid/ $ export ORACLE_HOME
C shell:
% setenv ORACLE_SID +ASM % setenv ORACLE_HOME /u01/app/oracle/product/11.2.0/grid
Using SQL*Plus, connect to the Oracle ASM instance as the SYS user with SYSASM privilege and start the instance if necessary:
# $ORACLE_HOME/bin/sqlplus /nolog
SQL> CONNECT SYS as SYSASM
Enter password: SYS_password
SQL> STARTUP
Enter the following command to view the existing disk groups, their redundancy level, and the amount of free disk space in each one:
SQL> SELECT NAME,TYPE,TOTAL_MB,FREE_MB FROM V$ASM_DISKGROUP;
From the output, identify a disk group with the appropriate redundancy level, and note the free space that it contains.
If necessary, install or identify the additional disk devices required to meet the storage requirements listed in the previous section.
The Oracle Database software is available on installation media, or you can download it from the Oracle Technology Network Web site, or the Oracle Software Delivery Cloud portal. To install the software from the hard disk, you must either download it and unpack it, or copy it from the installation media, if you have it.
You can access and install Oracle Database by using one of the following methods:
To copy the software to a hard disk, see "Copying the Software to the Hard Disk"
To download the software from Oracle Technology Network, see "Downloading Oracle Software"
You can download the trial version of the installation files from the Oracle Technology Network (OTN) or the Oracle Software Delivery Cloud portal and extract them on your hard disk. Ensure that you review and understand the terms of the license. Most downloads include the development license. This section contains the following topics:
To download the installation archive files from Oracle Technology Network:
Use any browser to access the software download page from Oracle Technology Network:
http://www.oracle.com/technetwork/indexes/downloads/index.html
Go to the download page for the product to install.
On the download page, identify the required disk space by adding the file sizes for each required file.
The file sizes are listed next to the file names.
Select a file system with enough free space to store and expand the archive files.
In most cases, the available disk space must be at least twice the size of all of the archive files.
On the file system that you selected in Step 4, create a parent directory for each product, for example OraDB11g, to hold the installation directories.
Download all of the installation archive files to the directory that you created in Step 5.
Verify that the files you downloaded are the same size as the corresponding files on Oracle Technology Network.
Extract the files in each directory that you just created.
After you have extracted the required installation files, see "Installing the Oracle Database Software" .
You can download the software from Oracle Software Delivery Cloud as Media Packs. A Media Pack is an electronic version of the software that is also available to Oracle customers on CD-ROM or DVD. To download the Media Pack:
Use any browser to access the Oracle Software Delivery Cloud portal:
https://edelivery.oracle.com/
Complete the Export Validation process by entering information (name, company, email address, and country) in the online form.
In the Media Pack Search page, specify the Product Pack and Platform to identify the Media Pack you want to download. If you do not know the name of the Product Pack, you can search for it using the License List.

After you review the Readme, choose the appropriate Media Pack from the search results to download the individual zip files. Follow the Download Notes instructions in this page. After you download and extract the contents of the required zip files, proceed with the installation of the software.
Note:
Print the page with the list of downloadable files. It contains a list of part numbers and their corresponding descriptions that you may refer during the installation process.See Also:
Frequently Asked Questions section on the Oracle Software Delivery Cloud portal for more information about Media PacksTo extract the installation archive files, perform the following steps:
If necessary, change to the directory that contains the downloaded installation archive files.
If the downloaded file has the zip extension, use the following command to extract the content:
unzip file_name.zip
If the downloaded file has the cpio.gz extension, use the following command:
$ gunzip filename.cpio.gz
This command creates files with names similar to the following:
filename.cpio
To extract the installation files, enter a command similar to the following:
$ cpio -idcmv < filename.cpio
Note:
See the download page for information about the correct options to use with thecpio command.
Some browsers uncompress files while downloading them, but they leave the .gz file extension.
For each file, this command creates a subdirectory named Diskn, where n is the disk number identified in the file name.
When you have extracted all of the required installation files, see the "Installing the Oracle Database Software".
Before installing Oracle Database, you might want to copy the software to the hard disk to enable the installation process to run faster. Before copying the installation media content to the hard disk, you must mount the disk. The following sections describe how to mount the disk and copy its content to the hard disk.
On most Linux systems, the disk mounts automatically when you insert it into the disk drive. If the disk does not mount automatically, then follow these steps to mount it:
If necessary, log in as the root user and enter a command similar to one of the following to eject the currently mounted disk, then remove it from the drive:
Asianux, Oracle Linux, and Red Hat Enterprise Linux:
# sudo eject /mnt/dvd
SUSE Linux Enterprise Server:
# eject /media/dvd
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the installation media.
Insert the appropriate installation media into the disk drive.
To verify if the disk is mounted automatically, enter one of the following commands depending on the platform:
Asianux, Oracle Linux, and Red Hat Enterprise Linux:
# ls /mnt/dvd
SUSE Linux Enterprise Server:
# ls /media/dvd
Before running the following command, ensure that the /mnt/dvd directory exists on Red Hat Enterprise Linux. If not, create the /mnt/dvd as required, to mount the installation media.
If this command fails to display the contents of the installation media, enter a command similar to the following to mount it, depending on the platform:
Asianux, Oracle Linux, and Red Hat Enterprise Linux:
# mount -t iso9660 /dev/dvd /mnt/dvd
SUSE Linux Enterprise Server:
# mount -t iso9660 /dev/dvd /media/dvd
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the installation media.
If Oracle Universal Installer displays the Disk Location dialog box, enter the disk mount point directory path, for example:
/mnt/dvd
To continue, go to one of the following sections:
To copy software to a hard disk, see "Copying the Oracle Database Software to a Hard Disk".
To install the software from the installation media, see "Installing the Oracle Database Software".
Note:
If the system does not have an installation media, you can copy the software from the disk to a file system on another system, then either mount that file system using NFS or use FTP to copy the files to the system where you want to install the software.To copy the contents of the installation media to a hard disk:
Create a directory on the hard disk, outside of the Oracle base directory, to hold the Oracle software:
$ mkdir OraDb11g
Change the directory to the directory you created in Step 1:
$ cd OraDb11g
Mount the disk, if it is not mounted.
Some platforms automatically mount the disk when you insert it into the drive. If the disk does not mount automatically, see the "Mounting Disks" section for platform-specific information.
Copy the contents of the mounted disk to the corresponding new subdirectory as follows:
$ cp -R /directory_path OraDb11g
In this example, /directory_path is the disk mount point directory.
If necessary, mount the next disk and repeat Step 4.
During installation, you are prompted to select a database security configuration. The Secure Configuration option configures the database with database auditing options, and password policy and expiration settings.
For new database installations, the default configuration for Oracle Database 11g Release 2 (11.2) includes the Secure Configuration option. To disable these enhanced security controls you can deselect the Assert all new security settings check box in the Specify Configuration Option screen that appears during the database installation. Oracle Database is then installed with default options for Oracle Database 10g Release 2. You can enable or disable auditing or password security settings, or revert to a previous security setting. After installation, you can enable or disable the security configuration by starting Database Configuration Assistant through the command-line interface.
To enable the security configuration:
dbca -silent -configureDatabase -sourceDB SID -disableSecurityConfiguration NONE -enableSecurityConfiguration true
To disable the security configuration:
dbca -silent -configureDatabase -sourceDB SID -disableSecurityConfiguration [ALL|PASSWORD_PROFILE] -enableSecurityConfiguration false
SID is the system identifier.
For database upgrades, the upgraded database retains your existing database security configuration to ensure compatibility with existing applications.
Starting with Oracle Database 11g Release 2 (11.2), the Security Enhanced Linux (SELinux) feature is supported for Oracle Linux 4, Red Hat Enterprise Linux 4, Oracle Linux 5, and Red Hat Enterprise Linux 5.
Note:
Oracle recommends configuring your database with the Secure Configuration option either during installation or after installation using Database Configuration Assistant.
Database Vault is an enhanced security feature. If it is installed with the database, then you cannot change the secure configuration using the Database Configuration Assistant option.
In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install Oracle Database. The instructions in this section explain how to run the Oracle Universal Installer GUI to perform most database installations.
Note:
If you plan to use Oracle Restart or Oracle ASM, then you must install Oracle Grid Infrastructure before you install and create the database. Otherwise, you must manually register the database with Oracle Restart. For information about installing Oracle Grid Infrastructure, see "Installing and Configuring Oracle Grid Infrastructure for a Standalone Server".
You may have to shut down existing Oracle processes before you start the database installation. See "Stopping Existing Oracle Processes".
To install Oracle Database by using the silent or response file installation method, without the GUI, see Appendix A. This method is useful to perform multiple installations of Oracle Database. This appendix also describes other advanced installation topics.
For any type of installation process, start Oracle Universal Installer and install the software, as follows:
Logon as the Oracle software owner user (typically, oracle) to the computer on which you want to install Oracle components.
If you are installing the software from installation media, mount the disk if it is not mounted.
If the disk does not mount automatically, see the "Mounting Disks" section for platform-specific information.
Some platforms automatically mount the disk when you insert the installation media into the drive.
To start Oracle Universal Installer, complete one of the following steps depending on the location of the installation files:
Note:
Start Oracle Universal Installer from the terminal session where you logged in as theoracle user and set the user's environment.If the installation files are on installation media, enter commands similar to the following, where directory_path is the path of the database directory on the installation media:
$ /directory_path/runInstaller
If the installation files are on the hard disk, change the directory to the database directory and enter the following command:
$ ./runInstaller
Downloading Updates Before Installation
Starting with Oracle Database 11g Release 2 (11.2.0.2), if you plan to run the installation in a secured data center, then you can download updates before starting the installation by starting Oracle Universal Installer on a system that has Internet access in update download mode. To start Oracle Universal Installer to download the updates, enter the following command:
$ ./runInstaller -downloadUpdates
Provide the My Oracle Support user name and password, and provide proxy settings, if needed, in the Provide My Oracle Support credentials screen. Then, enter the Download location and click Download in the Download software updates screen. If updates are available, then they are downloaded in the location provided. The Finish Updates screen shows the successful download of the updates. Click Close.
After you download the updates, transfer the update file to a directory on the server where you plan to run the installation.
