If an agent is not found on the local host, then this option is disabled during installation. If you are setting up a single database for the first time, then it is recommended that you configure local management with Oracle Enterprise Manager, which is the default. You can later install additional databases and configure central management using Enterprise Manager. You specify whether automated backups should be configured for the database. If you choose this option, you must specify whether the recovery area should be stored on the local file system or in an Oracle ASM disk group.
You must also specify the operating system credentials the backup job uses when performing backups. When you create a database, certain administrative user accounts are created automatically. You can use the same password for each account, or specify passwords for each account individually. If you do not enter a secure password, you will receive a warning message during installation. Administrative access to the database is granted by membership in certain operating system groups. This section briefly describes the steps for a desktop-class installation. Most steps are common to all platforms and involve running the Oracle Universal Installer.
Platform-specific steps are noted. For further assistance, consult the online Help or the Oracle Database Installation Guide for your platform. Log on to your computer as a member of the administrative group that is authorized to install Oracle Database software and to create and run the database. Refer to your operating system-specific documentation or contact your system administrator to determine whether you have the necessary privileges and permissions to install new software. If you are installing from distribution media, then insert the distribution media for the database into your computer.
If you downloaded the installation software from the Oracle Web site, then follow the instructions on the site to run the Oracle Universal Installer. Or, see the Oracle Database Installation Guide for your platform. The first window that appears is the Configure Security Updates window. To receive notifications about security issues via e-mail, enter your e-mail address in the Email text field. To receive security updates from My Oracle Support, enter the e-mail address registered with My Oracle Support, select the I wish to receive security updates Choose the Create and configure a database option.
Or, you also have the option of choosing to only install the database software, but then you must create a database in an additional step after the software is installed. If you are currently using a previous version of Oracle Database, choose Upgrade an existing database. After you have chosen an option, click Next. You can choose the Server Class option to customize your installation.
For example, you use this method to configure Oracle Automatic Storage Management for your database, install the Sample Schemas, or configure automated backups. Selecting this option guides you through a series of installation steps that are not documented in this guide. For more information about the advanced choices, see "About Advanced Installation".
Also see Oracle Database Installation Guide for your platform.
Provide the following configuration details for the database:. Oracle Base Location— The Oracle base directory helps to facilitate the organization of multiple Oracle software installations. You can click Browse to find the directory you want to act as the Oracle base directory.
Software Location—The software location is the Oracle home for your database. You must specify a new Oracle home directory for each new installation of Oracle Database software. By default, the Oracle home directory is a subdirectory of the Oracle base directory. You can click Browse to find the directory where you want to install the Oracle Database software. Database File Location—The database file location is the location where Oracle Database files are stored. You can click Browse to select a different location. See "Installation Type". Character Set—Choose the character set to use to store the data within the database.
You can choose between the Default , which is based on the operating system language settings, or Unicode. Host computer users in this group have administrative privileges on the database. This group is typically named dba. Global Database Name—Enter the fully qualified global database name. See "Installation Type" for more on global database name. If the password you choose is not a secure password, a warning message will be displayed. If Oracle software has not previously been installed on this server, then the Create Inventory window appears.
If this is not the first installation attempt on this server, then the Perform Prerequisite Checks window appears. For first time installations on Linux and UNIX operating systems only , specify a directory for installation files and the name of an operating system group that has write permissions for that directory.

If this is the first time you are installing any Oracle software on this computer, then the Create Inventory Directory window appears. You must specify a local directory for the inventory, which OUI uses to keep track of all Oracle software installed on the computer. This information is used while applying patches or upgrading an existing installation, and while deinstalling Oracle software.
Note that this directory is different from the Oracle home directory.

In this window you can also specify the operating system group that has write permissions on the inventory directory. This prevents other users from writing over the Oracle product installation files. Typically the oinstall group is selected. After you enter a directory path and optionally specify an operating system group, click Next to continue. OUI performs several environment checks and indicates whether the check was a success, or resulted in a warning or failure. Details of the checks are provided in the displayed window.
The installation can proceed only when all checks have a status of either Succeeded or Warning. If any of the environment checks failed, then they must be resolved manually. See "Checking Prerequisites" for more information. If all the prerequisite checks passed, or after you click Next , the Summary window appears,. Review the installation summary, then click Finish to start the installation. The Install window appears, showing the installation progress. After the installation phase, the Configuration Assistants window appears.
This window lists the configuration assistants that are started automatically. If you chose to create a starter database, then Database Configuration Assistant starts automatically in a separate window. Optional Click Password Management to unlock user accounts to make the accounts accessible to users. In the Execute Configuration Scripts window, you are prompted to open a new terminal window, and to run scripts as the root user. After you run the scripts, return to this window and click OK. Your installation and database creation is now complete.
DBCA then creates a database using the information you provided. If you do not create a starter database and later want to create one, or to create additional databases, use DBCA. DBCA also enables you to modify a database configuration, delete a database, and more. This section describes the following DBCA tasks:. Online Help is available by clicking Help. It provides information that guides you in selecting configuration options.
In the Operations window, select Create a Database and click Next to start the guided workflow for creating a database. The workflow requests your input in the following windows:. This window enables you to select the type of database to create.

You can use DBCA to create a database from templates supplied by Oracle or from templates that you create. The templates contain settings optimized for a particular type of workload. Click Show Details to see the configuration for each type of database.
Select the template suited to the type of workload your database will support. If you are not sure which to choose, then select the default General Purpose or Transaction Processing template. For more complex environments, you can select the Custom Database option. This option does not use templates and results in a more extensive interview, which means that it takes longer to create your database.
In the SID field, enter the system identifier. The SID defaults to the database name and uniquely identifies the instance that runs the database. Use this window to set up your database so it can be managed with Oracle Enterprise Manager. Oracle Enterprise Manager provides Web-based management tools for individual databases, and central management tools for managing your entire Oracle environment. Then, select one option:.
If the Oracle Management Agent is installed on your host computer, then you can choose central management by selecting Register with Grid Control for centralized management and then selecting the Management Service. To manage your database locally, select Configure Database Control for local management.
You can then optionally configure e-mail notification of database alerts or a daily backup of the database. In this window, specify the type of storage you would like your database to use.

For more information, see "About Advanced Installation". Later, you can make modifications to database file names and locations. All the database files are created in this location. Use Oracle Managed Files —This option instructs Oracle Database to directly manage operating system files comprising an Oracle database. You specify the default location, called a database area, for all your files.

Oracle Database thereafter automatically creates and deletes files in this location, as required. You can also create multiple copies of your redo and online log files by selecting Multiplex Redo Logs and Control Files. To learn more about online redo log files and control files, see Chapter 9, "Performing Backup and Recovery". Selecting this option enables you to delegate the complete management of database files to the database. You no longer have to specify the file names, their location, or their sizes.
When you create a new database, it is important to configure the database so you can recover your data if a system failure occurs. Online redo log files contain a record of changes that were made to data files. Online redo log files are stored in online redo log groups. You must have at least two online redo log groups for your database.
After the online redo log files in a group have filled up, the log writer process LGWR switches the writing of redo records to a new online redo log group. Oracle Database can automatically save the inactive group of online redo log files to one or more offline destinations, known collectively as the archived redo log also called the archive log.
The process of turning online redo log files into archived redo log files is called archiving. A group of online redo log files cannot be reused by the log writer LGWR process until the group is archived. Only the most recent changes made to the database, which are stored in the online redo log files, are available for instance recovery.
A database backup, with online and archived redo log files, guarantees that you can recover all committed transactions if the operating system or hardware fails. You can recover the database using a backup that was taken while the database was open and being used, if you have a copy of the archived log files that were written while the database was being backed up. You can perform online tablespace backups, and use these backups to restore a tablespace following media failure.
You can keep a standby database current with its original database by continuously applying the original archived redo log files to the standby database. Before you can archive the online redo log files, you must determine the destination to which you want to archive. Oracle recommends that the archive log be stored in a fast recovery area because it can simplify backup and recovery operations for your database.
A fast recovery area is a location in which Oracle Database can store and manage files related to backup and recovery. It is distinct from the database area, which is a location for the current database files data files, control files, and online redo log files. Specify Fast Recovery Area —Select this option to specify a backup and recovery area and its directory location and size.
You can use variables to identify standard locations. Enable Archiving —Select this option to enable the archiving of database online redo log files, which can be used to recover a database. Oracle recommends you select Enable Archiving. Selecting this option provides better protection for your database for software or hardware failure.
Oracle guides and educational materials contain examples based upon the Sample Schemas. Oracle recommends that you include them in your database. Scripts are useful for performing postinstallation tasks, such as loading custom schemas. Note that if you choose to run scripts after installation, then your scripts must include a connection string that identifies the database.
