6 Installing Oracle Database

You can use the media for installing Oracle Database on all supported operating systems. This chapter covers the following topics:

Preinstallation Considerations for Installing Oracle Database
Reviewing Component-Specific Installation Guidelines
Accessing the Installation Software
Installing the Oracle Database Software
Cloning an Oracle Home
Configuring Oracle Configuration Manager in a Cloned Oracle Home

6.1 Preinstallation Considerations for Installing Oracle Database

The Oracle Database software is available on installation media or you can download it from the Oracle Technology Network (OTN) website. 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 without the GUI by supplying a response file with silent or response file mode.

Note:

Windows requires Administrator privileges at the command prompt.

Complete the requirements described in Chapter 3, "Oracle Database Preinstallation Tasks" and "Reviewing Component-Specific Installation Guidelines" before you begin the installation.

Next, consider the following issues:

Installation Consideration on Windows
Performing Multiple Oracle Database Installations
Installing on Systems That Already Have Oracle Components
Installing with Minimum Memory Requirements

6.1.1 Installation Consideration on Windows

On Windows, command prompts should be opened with Administrator privileges.

6.1.2 Performing Multiple Oracle Database Installations

If you must perform multiple installations of Oracle Database, then you may want to use either of the following methods to install Oracle Database:

Response files: At each node, you run Oracle Universal Installer from the command line using silent or response file mode and you supply a response file to provide information Oracle Universal Installer needs. The response file is a text file containing the settings you normally enter in the Oracle Universal Installer GUI dialog boxes.

See Also:
Appendix C, "Installing and Configuring Oracle Database Using Response Files"
Cloning the Oracle home of an existing Oracle Database installation: With this method, you install one instance of Oracle Database, and then clone its Oracle home for each additional installation.

"Cloning an Oracle Home"

6.1.3 Installing on Systems That Already Have Oracle Components

See Also:

"Upgrade Considerations" before running Oracle Universal Installer

Follow these steps when other components exist on your computer:

Log on as a member of the Administrators group for the computer on which you want to install Oracle components.

If you are installing on a Primary Domain Controller (PDC) or a Backup Domain Controller (BDC), log on as a member of the Domain Administrators group.
Delete the ORACLE_HOME environment variable if it exists. See the Microsoft online help for more information about deleting environment variables.

Note:
The ORACLE_HOME environment variable is automatically set in the registry. Manually setting this variable prevents installation.
Back up any databases you must upgrade. Review "Upgrade Considerations" for more information.

Chapter, "Preinstallation Checklist" in Oracle Real Application Clusters Installation Guide before running Oracle Universal Installer

6.1.4 Installing with Minimum Memory Requirements

Installations of Oracle Database on computers with RAM and virtual memory lesser than the minimum required have the following limitations:

Computers cannot run Oracle Database Upgrade Assistant, Oracle Database Configuration Assistant, or Oracle Net Services Configuration Assistant during an Oracle Universal Installer installation session.
Depending on how many applications run on the computer, you must further increase the paging file size or reduce the size of the System Global Area (SGA) if you run out of virtual memory. If temporary files and the paging file are both stored on the same physical drive, the space requirements for one may limit the size of another. If your system has limited free space, first install the Oracle Database software. After the installation is finished, create a database with Oracle Database Configuration Assistant.

Note:

Do not install the database on computer systems that barely meet the minimum memory and virtual memory requirements of 1 GB.

You can install only the database software by selecting the Install Database Software only option provided on the Select Installation Option screen.

After installation, run the appropriate configuration assistant for your needs:

To create a new database, run Oracle Database Configuration Assistant. From the Start menu, select All Programs, then Oracle - HOMENAME, then Configuration and Migration Tools, then Database Configuration Assistant.
To upgrade an existing database, run Oracle Database Upgrade Assistant. From the Start menu, select All Programs, then Oracle - HOMENAME, then Configuration and Migration Tools, then Database Upgrade Assistant.

6.2 Reviewing Component-Specific Installation Guidelines

Review the following guidelines before starting Oracle Universal Installer:

Oracle Universal Installer

Do not use Oracle Universal Installer from an earlier Oracle release to install components from this release.
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 Automatic Storage Management is part of an Oracle Grid Infrastructure installation, either for a cluster, or for a standalone server.

If you want to upgrade an existing Oracle Automatic Storage Management installation, then you must upgrade Oracle Automatic Storage Management by running an Oracle Grid Infrastructure upgrade. If you do not have Oracle Automatic Storage Management installed and you want to use Oracle Automatic Storage Management as your storage option, then you must complete an Oracle Grid Infrastructure for a standalone server installation before you start your Oracle Database installation.

See Also:
"Oracle Grid Infrastructure for a Standalone Server" for information about Oracle Grid Infrastructure for a standalone server
Installations on a cluster

If Oracle Clusterware or Oracle RAC is installed on the system, Oracle Universal Installer displays the Grid Installation Options page. You must select Single instance database installation , unless you want to install Oracle RAC. The other options on the page are Oracle Real Application Clusters database installation and Oracle RAC One Node database installation.

See Also:
Oracle Real Application Clusters Installation Guide

6.2.1 Selecting the Database Character Set

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.

Once a database is created, changing its character set is usually very expensive in terms of time and resources. Such operation 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, LDAP. Unicode is ideally suited for databases supporting the Internet and the global economy.

As 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. Note that 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.

Legacy character sets should be considered 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 such case is the character set of most clients connecting to this database.

The database character set of a multitenant container database (CDB) determines which databases can be plugged in later. Ensure that the character set you choose for the CDB is compatible with the database character sets of the databases to be plugged into this CDB.

See Also:

"Choosing a Database Character Set for a Multitenant Container Database" in Oracle Database Globalization Support Guide

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. It is noteworthy that the same default is used by the database installation process on UNIX-based platforms. This results from the assumption that most clients connecting to the database run under the Microsoft Windows operating system. As the database should be able to store all characters coming from the clients and Microsoft Windows character sets have 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. In any case, Oracle 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 non-recommended character sets, choose 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 Windows.

See Also:

"Choosing a Character Set" in Oracle Database Globalization Support Guide

Caution:

AL32UTF8 is the Oracle Database character set that is appropriate for XMLType data. It is equivalent to the IANA registered standard UTF-8 encoding, which supports all valid XML characters.

Do not confuse Oracle Database database character set UTF8 (no hyphen) with database character set AL32UTF8 or with character encoding UTF-8. Database character set UTF8 has been superseded by AL32UTF8. Do not use UTF8 for XML data. UTF8 supports only Unicode version 3.0 and earlier; it does not support all valid XML characters. AL32UTF8 has no such limitation.

Using database character set UTF8 for XML data could cause an irrecoverable error or affect security negatively. If a character that is not supported by the database character set appears in an input-document element name, a replacement character (usually a question mark) is substituted for it. This terminates parsing and raises an exception.

6.2.2 Using an Oracle Automatic Storage Management Disk Group

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 Automatic Storage Management disk group that you created during the Oracle Grid Infrastructure for a standalone server installation.

Note:

The Oracle Automatic Storage Management instance that manages the existing disk group runs in a different Oracle home directory.

To determine whether an existing Oracle Automatic Storage Management disk group exists, or to determine whether there is sufficient disk space in a disk group, use the following procedure:

In the Services Control Panel, ensure that the OracleASMService+ASM service has started.
Open command prompt and temporarily set the ORACLE_SID environment variable to specify the appropriate value for the Oracle Automatic Storage Management instance.

For example, if the Oracle Automatic Storage Management SID, which is named +ASM, is located in the asm directory, you would enter the following setting:
```
DRIVE_LETTER:\>set ORACLE_SID=+ASM
```
Connect to the Oracle Automatic Storage Management instance as the SYS user with the SYSASM privilege and start the instance if necessary:
```
DRIVE_LETTER:\>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 section "Selecting the Database Character Set".

Note:
If you are adding devices to an existing disk group, then Oracle recommends that you use devices that have the same size and performance characteristics as the existing devices in that disk group.

6.3 Accessing the Installation Software

6.4 Installing the Oracle Database Software

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.

See Also:

If you plan to use Oracle Restart or Oracle Automatic Storage Management, then you must install Oracle Grid Infrastructure for a standalone server 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 Services"
Appendix C, "Installing and Configuring Oracle Database Using Response Files" to install Oracle Database using the silent or response file installation method, without the GUI. It also explains how to clone an existing Oracle home. These methods are useful to perform multiple installations of Oracle Database.

To install the Oracle Database software:

Log in to Windows as an Administrator user.

If you are installing on a Primary Domain Controller (PDC) or a Backup Domain Controller (BDC), log on as a member of the Domain Administrators group.
If you are installing Oracle Database on a computer with multiple Network Interface Cards or multiple aliases, use System in the Control Panel to create the ORACLE_HOSTNAME system environment variable. Set this variable to point to the host name of the computer on which you are installing Oracle Database.

Select ASM Disk Group	This screen is displayed only if you select Oracle Automatic Storage Management as your storage option. Disk groups are created during the Oracle Grid Infrastructure installation. Disk groups are configured with the `SYSASM` privilege using `asmcmd` or `SQL create diskgroup` commands. An ASM disk group consists of multiple disk partitions. The table in this screen displays existing disk groups created during the Oracle Grid Infrastructure installation. Select a disk group to use for database file storage.
Specify Schema Passwords	Enter and confirm passwords for the privileged database accounts: SYS, SYSTEM, and DBSNMP. If you chose to create the database as a CDB, then Oracle Universal Installer also asks for the PDBADMIN password. Click Next. Note: Optionally, you can use the same password for all accounts. However, Oracle recommends that you specify a different password for each account. You must remember the passwords that you specify. See Also: "Unlocking and Resetting User Passwords" for information about password guidelines
Perform Prerequisite Checks	This option checks if the minimum system requirements to perform the database installation are met. Click Fix & Check Again, if you want the installer to fix the problem and check the system requirements once more. If you click Check Again, then you can run the prerequisite check again to see if the minimum requirements are met to carry on with the database installation. To get a list of failed requirements, select Show Failed from the list. To get a list of all the prerequirement checks run by the OUI, select Show All. To get a list of the prerequirement checks that are successful, select Show Succeeded. Note: Oracle recommends that you use caution in checking the Ignore All option. If you check this option, then Oracle Universal Installer may not confirm that your system can install Oracle Database successfully. See Also: "Oracle Database Preinstallation Tasks" for information about the system requirements
Summary	Review the information displayed on this screen, and click Install. Note: You can save all the installation steps into a response file by clicking Save Response File. Later, this file can be used for a silent installation.
Install Product	This screen displays the progress of a database installation. It also shows the status information while the product is being installed. Click Next. This screen then displays the status information for the configuration assistants that configure the software and create a database. When the message is displayed after Database Configuration Assistant process, click OK to continue.
Finish	This screen is shown automatically when all the configuration tools are successful.

6.5 Cloning an Oracle Home

You can copy an existing Oracle home and then configure it for a new environment. This process is called cloning. If you are performing multiple Oracle Database installations, you may want to use this method to create each new Oracle home, because copying files from an existing Oracle Database installation takes less time than creating a new version of them. This method is also useful if the Oracle home that you are cloning has patches applied to it. When you clone an Oracle home, the new Oracle home has the patch updates.

Note:

Oracle Database Administrator's Guide covers cloning Oracle databases in detail, and cloning Oracle homes.

To clone an Oracle home:

Ensure that the Oracle Database installation whose home you want to clone has been successful.

You can check the success of the installation by reviewing the installActionsdate_time.log file for the installation session, which is normally located in the C:\Program Files\Oracle\Inventory\logs directory.

If you have installed patches, you can check their status by running the following commands at a command prompt:
```
C:\ORACLE_HOME\OPatch> set ORACLE_HOME=ORACLE_HOME_using_patch
C:\ORACLE_HOME\OPatch> opatch lsinventory
```
Stop the Oracle-related services on this computer.

You can stop Oracle services by using one of the following methods:
- Oracle Administration Assistant for Windows: From the Start menu, select All Programs, then Oracle - HOMENAME, then Configuration and Migration Tools, then Administrative Assistant for Windows, then Oracle Managed Objects, then Computers, and then machine-name. Select Databases, then right-click global database name, select Stop Service.
  
  Note:
  Choose Startup/Shutdown Options to control whether a database instance should be stopped along with the service.
- Microsoft Windows Services utility: From the Start menu, select Control Panel, then Administrative Tools, then Services. Right-click any service that begins with Oracle, and then from the menu, select Stop.
Create a ZIP file with the Oracle home (but not Oracle base) directory, selecting the Save full path info option.

For example, if the source Oracle installation is in C:\app\username\product\12.1.0\dbhome_1, you zip the dbhome_1 directory, leaving out the admin, flash_recovery_area, and oradata directories that are under 12.1.0. These directories are created in the target installation later on when you create a new database there.
Copy the ZIP file to the root directory of the target computer.
Extract the ZIP file contents, selecting the Use folder names option.
Repeat steps 4 and 5 for each computer where you want to clone the Oracle home, unless the Oracle home is on a shared storage device.
In the source Oracle home, restart the services that you stopped in step 2.
On the target computer, cd to the unzipped Oracle home directory, and perform the following steps:
1. Remove the *.ora files that are present in unzipped ORACLE_HOME\network\admin directory, such as listener.ora, sqlnet.ora, and tnsnames.ora.
2. From the clone\bin directory, run clone.pl for the unzipped Oracle home. Use the following syntax:
```
C:\ORACLE_HOME\clone\bin>
ORACLE_HOME="target location" ORACLE_BASE="target Base location" ORACLE_HOME_USER="Windows User Account"

-defaultHomeName 
```
  where ORACLE_HOME_USER="Windows User Account" is the Oracle Home User for the cloned home.
  
  Windows Built-in Account is used as the Oracle Home User if the parameter for ORACLE_HOME_USER is not specified.
  
  For example:
```
C:\ORACLE_HOME\clone\bin> <target home>\perl\bin\perl.exe clone.pl 
 
ORACLE_HOME="C:\app\username\product\12.1.0\dbhome_1" 
ORACLE_BASE="C:\app\username"
ORACLE_HOME_USER="mydomain\username" -defaultHomeName
```
Oracle Universal Installer starts, and then records the cloning actions in the cloneActionstimestamp.log file. This log file is normally located in C:\Program Files\Oracle\Inventory\logs.
To configure connection information for the new database, run Net Configuration Assistant.

To start Net Configuration Assistant, select Start, then All Programs, then Oracle - HOMENAME, then Configuration and Migration Tools, and then Net Configuration Assistant.
To create a new database for the newly cloned Oracle home, run Oracle Database Configuration Assistant.

To start Oracle Database Configuration Assistant, select Start, then All Programs, then Oracle - HOMENAME, then Configuration and Migration Tools, and then Database Configuration Assistant.

6.6 Configuring Oracle Configuration Manager in a Cloned Oracle Home

Configuring Oracle Configuration Manager for a cloned Oracle home depends on its configuration in the original Oracle home.

If you have already installed but not configured Oracle Configuration Manager in the original Oracle home, then run the following commands from the cloned Oracle home:

DRIVE_LETTER:\> cd %ORACLE_HOME%\ccr\bin
DRIVE_LETTER:\> setupCCR

If you have already configured Oracle Configuration Manager in the original Oracle home, then run the following commands from the cloned Oracle home:

DRIVE_LETTER:\> cd %ORACLE_HOME%\ccr\bin
DRIVE_LETTER:\> deriveCCR

If deriveCCR cannot find the original configuration, then the Oracle Configuration Manager command-line interface prompts for the My Oracle Support credentials (MOS). Then, deriveCCR configures Oracle Configuration Manager in disconnected mode.

Run the following command to reconfigure Oracle Configuration Manager after running the deriveCCR command:

DRIVE_LETTER:\> configCCR
