Creating Disk Groups for a New Oracle Installation

This section describes the basic procedure to follow when creating disk groups during a new installation of Oracle Restart and Oracle Database. This information also applies to an Oracle Grid Infrastructure installation.

The procedure assumes that the data disk group is used for the storage of the database data files and the fra disk group is used for storage of the fast recovery area files. Detailed information about installation with Oracle Universal Installer (OUI) and database creation with Database Configuration Assistant (DBCA) is available in the installation guides for your specific operating system.

  1. Install Oracle Restart with OUI, following the screen prompts.

    During the installation, create the data disk group for storing database files such as the data and control files.

    This OUI process is similar to creating a disk group with Oracle ASM Configuration Assistant (ASMCA). For information about using ASMCA to create disk groups, see "Managing Disk Groups with ASMCA".

    The data disk group is the disk group used for storing Oracle Cluster Registry (OCR) and voting files in an Oracle Grid Infrastructure installation. See "Storing Oracle Cluster Registry and Voting Files in Oracle ASM Disk Groups"

  2. After Oracle Restart is installed, use ASMCA to create the fra disk group for storing the fast recovery area files.

    Create the fra disk group to hold the fast recovery area files.

    At this time, you can also update the data disk group if necessary. For information about using ASMCA to create or alter disk groups, see "Managing Disk Groups with ASMCA".

    You can also create the fra disk group with SQL*Plus or ASMCMD commands run from the Oracle Restart home. For information, see "Using the CREATE DISKGROUP SQL Statement" and "mkdg".

  3. Install the Oracle Database software with OUI, following the screen prompts.

  4. After the database software has been installed, run DBCA to create a database, following the screen prompts.

    During the creation of the database, make the appropriate selections to use Oracle ASM for storage of data files and fast recovery area files. When prompted:

    • Store database data files in the data disk group

    • Store fast recovery area files in the fra disk group
