You must choose a location for recovery files only if you intend to enable automated backups during the installation.If you place the Oracle recovery files on a file system, use the following guidelines when deciding where to place them To prevent disk failure from making both the data files and the recovery files unavailable, place the recovery files in a file system on a different physical disk from the data files.Note. Alternatively, for both data files and recovery files, use an Automatic Storage Management disk group.The file system that you choose should have at least 2 GB of free disk space.The disk space requirement is the default disk quota configured for the flash recovery area specified by the DBRECOVERYFILEDESTSIZE initialization parameter.If you choose the Custom installation type or the Advanced database configuration option, you can specify a different disk quota value.After you create the database, you can also use Oracle Enterprise Manager Grid Control or Database Control to specify a different value.The default location suggested by Oracle Universal Installer for the database file directory is a subdirectory of the Oracle base directory.However, this default location is not recommended for production databases.Creating Required Directories.Note. You must complete this procedure only if you want to place the Oracle database or recovery files on a separate file system from the Oracle base directory.To create directories for the Oracle database or recovery files on separate file systems from the Oracle base directory, follow these steps Use Windows Explorer to determine the free disk space on the file system.From the display, identify the file systems that you want to use File Type.File System Requirements.Data files. Choose either.A single file system with at least 9.MB of free disk space.Two or more file systems with at least 9.MB of free disk space in total.Recovery files. Choose a file system with at least 2 GB of free disk space.If you are using the same file system for more than one type of file, add the disk space requirements for each type to determine the total disk space requirement.Note the names of the directories for the file systems that you identified.If you also want to use Automatic Storage Management, see Preparing Disk Groups for an Automatic Storage Management Installation for instructions.Otherwise see the Stopping Existing Oracle Services section.Preparing Disk Groups for an Automatic Storage Management Installation.If you plan to use Automatic Storage Management to manage database files for your databases, use the procedures in this section to prepare disk groups before you install an Automatic Storage Management instance.This section covers the following topics 2.General Steps for Preparing Disk Groups for an Automatic Storage Management Installation.You will follow these general steps to configure Automatic Storage Management Identify your sites storage requirements.Optionally, use an existing Automatic Storage Management disk group.If you are creating a new Automatic Storage Management disk group, create partitions for direct attached storage DAS or storage area network SAN disks.Use one of the following methods to complete the Automatic Storage Management configuration If you plan to install Oracle Database using interactive mode, Oracle Universal Installer prompts you for the Automatic Storage Management disk configuration information during the installation.If you plan to install Oracle Database using silent or noninteractive mode, you will need to manually configure the disks before performing the installation.Step 1 Identifying Storage Requirements for Automatic Storage Management.To identify the storage requirements for using Automatic Storage Management, you must determine how many devices and the amount of free disk space that you require.To complete this task, follow these steps Determine whether you want to use Automatic Storage Management for Oracle data files, recovery files, or both.Note. You do not have to use the same storage mechanism for data file and recovery files.One storage mechanism can use the file system while the other uses Automatic Storage Management.If you plan to use Automatic Storage Management for both data files and recovery files, you should create separate Automatic Storage Management disk groups for the data files and the recovery files.If you plan to enable automated backups during the installation, you can choose Automatic Storage Management as the storage mechanism for recovery files by specifying an Automatic Storage Management disk group for the flash recovery area.Depending how you choose to create a database during the installation, you have the following options If you select an installation method that runs Oracle Database Configuration Assistant in interactive mode, by choosing the Advanced database configuration option for example, then you can decide whether you want to use the same Automatic Storage Management disk group for data files and recovery files, or you can choose to use different disk groups for each file type. 100 Android Paid Applications Apps For Iphone . Ideally, you should create separate Automatic Storage Management disk groups for data files and recovery files.
