Specify Configuration Options

Memory

Specify the amount of physical memory (RAM) that you want to allocate for the database. Oracle Universal Installer computes and displays a default value for the memory allocation in the Allocated Memory spin box and adjusts the slider bar accordingly. The values of the slide bar and spin box are also limited to the minimum and maximum values according to the available physical memory. You can use the slider bar or the spin box to specify a value (MB) for the amount of memory that you want to allocate for the database according to the requirements of the database.

Enable Automatic Memory Management option is selected by default. This option enables the database to automatically distribute the allocated memory between the System Global Area (SGA) and Program Global Area (PGA). If you deselect this option, then the SGA and PGA must be sized manually. If the option is selected, then the status of the memory distribution between the memory areas is displayed as AUTO on the screen. If the option is not selected, then the memory distribution between the memory areas is static. The ratio of the distribution of the allocated memory between the memory areas depends on the database configuration that you have selected.

The following is the ratio of the memory distribution according to the database types:

Character Sets

This option enables you to store the character data in the database in one of the following methods:

• Use the default - This option makes use of the operating system language settings.

• Use Unicode - This option enables you to store multiple language groups.

• Choose from the following list of character sets - This option enables the Select Database Character Set drop down list.

  To determine which character set to specify, you must decide which language groups you want to support in the database. You must apply these guidelines:

  • If you want to support the Euro symbol, then select WE8ISO8859P1, WE8MSWIN1252, or Unicode (AL32UTF8 or UTF8).

  • If you want to support only English, then select the default character set displayed by Oracle Universal Installer.

  • If you want to support both English and another language , then select the appropriate character set from the list.

    If your operating system is configured to use the other language, then the default character set displayed by Oracle Universal Installer may be the correct one to choose

  • If you want to support English and two or more other languages, or a language that is not listed, then select Unicode (AL32UTF8 or UTF8).

  Here is the list of languages and common character sets for a language group:

Security

Specify whether you want to disable the default security settings in the database.

The Assert all new security settings option is selected by default. Oracle provides enhanced security settings for the database. The setting includes enabling auditing and using new password profile.

Note: Oracle recommends that you use the default settings.

Sample Schemas

Specify whether you want to include the sample schemas in the database. Oracle provides sample schemas for use with product and documentation examples.

The Create database with sample schemas option is not selected by default. However, you can select the option, if you want to create the starter database with sample schemas.

Note: If you choose to install the sample schemas, then Oracle Database Configuration Assistant creates the EXAMPLES tablespace in the database, which requires 150 MB of disk space. If you are using raw devices for database storage, then you must create and specify a separate raw device for this tablespace. If you choose not to install the sample schemas, then you can manually create them in the database after the installation.
