If you intend to use a normal or high redundancy disk group, you can further protect your database against hardware failure by associating a set of disk devices in a custom failure group.
By default, each device comprises its own failure group. However, if two disk devices in a normal redundancy disk group are attached to the same SCSI controller, the disk group becomes unavailable if the controller fails.
The controller in this example is a single point of failure. To avoid failures of this type, you could use two SCSI controllers, each with two disks, and define a failure group for the disks attached to each controller. This configuration would enable the disk group to tolerate the failure of one SCSI controller. If you are sure that a suitable disk group does not exist on the system, install or identify appropriate disk devices to add to a new disk group. Use the following guidelines when identifying appropriate disk devices:.
All of the devices in an ASM disk group should be the same size and have the same performance characteristics. Do not specify more than one partition on a single physical disk as a disk group device. Automatic Storage Management expects each disk group device to be on a separate physical disk. Although you can specify a logical volume as a device in an Automatic Storage Management disk group, Oracle does not recommend their use.
If you want to use Automatic Storage Management as the storage option for either database or recovery files, and an existing Automatic Storage Management disk group exists, you have the following choices, depending on the installation method that you select:.
If you select an installation method that runs Oracle Database Configuration Assistant in interactive mode, by choosing the Advanced database configuration option for example, you can decide whether you want to create a new disk group or use an existing one. If you select an installation type that runs Oracle Database Configuration Assistant in noninteractive mode, you must choose an existing disk group for the new database. You cannot create a new disk group.
However, you can add disk devices to an existing disk group if it has insufficient free space for your requirements. To determine whether an existing ASM disk group exists, or to determine whether there is sufficient disk space in a disk group, you can use Oracle Enterprise Manager Grid Control or Database Control. Alternatively, you can use the following procedure:. Enter the following command to view the existing disk groups, their redundancy level, and the amount of free disk space in each one:.
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 the previous section.
Oracle recommends creating exactly one partition for each disk containing the entire disk. Before you can configure partitions or logical drives on Windows Server , you must enable disk automounting. Enable disk automounting when using:.
To create disk partitions, use the disk administration tools provided by the operating system or third party vendors. The following administration tools are provided by the operating system:. To access this tool, type diskmgmt.
Then select the Disk Management node in the Storage tree. On Windows Vista, create primary partitions and logical drives in extended partitions by selecting the New Simple Volume option.
To create a raw device, select Do not assign a drive letter or drive path. To mount the raw device, assign and remove a drive letter. Do not use spanned volumes or striped volumes. These options will convert the volume to a dynamic disk. Automatic Storage Management does not support dynamic disks. The command line tool diskpart. This tool is not included with the Windows operating system. You can download it from the Microsoft Windows Resource Kit.
The examples in this section use diskpart. To access this tool, enter diskpart. The syntax for using diskpart. You can enter the diskpart. In bit Windows, you cannot create more than four primary disk partitions on disk.
If you need more, you can get around this limitation by creating three primary partitions and then creating the fourth partition as an extended partition with as many logical partitions within as you need.
If you install Oracle Database in interactive mode, Oracle Universal Installer configures the disks' headers during the installation process. However, if you plan to install Oracle Database in noninteractive mode, you need to manually configure the disks before installation by using either asmtoolg GUI version or asmtool command-line version.
You can also use these tools to reconfigure the disks later on after installation. The asmtoolg and asmtool utilities only work on partitioned disks—you cannot use Automatic Storage Management on unpartitioned disks. The asmtoolg and asmtool tools associate meaningful, persistent names with disks to facilitate using those disks with Automatic Storage Management. Automatic Storage Management uses disk strings to more easily operate on groups of disks at once, so the names that asmtoolg or asmtool creates make this easier than using Windows drive letters.
The asmtoolg tool is a graphical interface for creating device names. Use asmtoolg to add, change, delete, and examine the devices available for use in Automatic Storage Management. In the installation media labeled Oracle Database 10 g Release 2 Select the Add or change label option, then click Next. The asmtoolg tool will show the devices available on the system. These are not available for use as disks and cannot be selected.
Automatic Storage Management can generate unique stamps for all of the devices selected for a given prefix. The stamps are generated by concatenating a number with the prefix specified. Select the Delete labels option, then click Next. The delete option is only available if disks exist with stamps. The delete window shows all stamped Automatic Storage Management disks. The asmtool utility is a command-line interface for stamping disks.
It has the following options:. However, if an existing Oracle Net listener process is using the same port or key value, Oracle Universal Installer can only configure the new listener; it cannot start it. To ensure that the new listener process starts during the installation, you must shut down any existing listeners before starting Oracle Universal Installer. Satisfy hardware and software requirements so that you can use authentication support with Oracle components.
All Oracle Enterprise Manager products must be the same release. Older versions of Enterprise Manager are not supported with the new release. If you choose the Custom installation type or the Advanced database creation option, you can use the Oracle-managed files feature with the new database.
If you use this feature, you need only specify the database object name instead of file names when creating or deleting database files. Configuration procedures are required to enable Oracle Managed Files. These Snap-ins require MMC version 1.
Install Internet Explorer version 5. If you install any Oracle Snap-ins before installing IE 5. Oracle Database Client is version 8. Oracle Database Client is not running as Administrator. Note: Ensure that the Telnet service is started on the Windows Services utility.
Platform-specific support information is as follows: Windows : Oracle supports installing, configuring, and running Oracle Database from a remote Terminal Services Client.
Oracle Migration Workbench is not supported on Windows Vista. Oracle Workflow is not supported on Windows Vista. Instead, use the Oracle Universal Installer that has been already installed on your system using the In the System Properties dialog box, click Advanced. Install a loopback adapter on the computer. See Also: "Installing a Loopback Adapter". Note: When you ping a computer from itself, the ping command should return the local IP address the IP address of the loopback adapter.
In the Welcome window, click Next. Click Next. In the Start Hardware Installation window, click Next. Oracle recommends the following non-routable addresses: Record the values you entered, which you will need later in this procedure. Leave all other fields empty. Click OK. Close the Network Connections window. Restart the computer. For example: Click Properties. Exit the System Control Panel.
Double-click Add Hardware to start the Add Hardware wizard. If you are using Windows , restart your computer. Close Network Connections. The remaining steps are same as given for Windows XP.
In the Hardware tab, click Device Manager. After you choose the storage method that you want to use for each file type, use the following sections to configure the required storage: Choosing a Storage Option for Oracle Data Files Choosing a Storage Option for Oracle Database Recovery Files Configuring Disk Storage Note: You do not have to use the same storage option for each type of file.
For information about how to configure disk storage before you start the installation, see one of the following sections depending on your choice: To use a file system for database or recovery file storage, see the "Creating Directories for Oracle Data Files or Recovery Files" section. Note: Alternatively, for both data files and recovery files, use an Automatic Storage Management disk group. Two or more file systems with at least MB of free disk space in total.
Recovery files Choose a file system with at least 2 GB of free disk space. Optionally, use an existing Automatic Storage Management disk group.
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 connect the computer to a network after installation, the Oracle Database instance on your computer can work with other instances on the network.
Remember that you must have installed a loopback adapter on your computer. When you install a loopback adapter, the loopback adapter assigns a local IP address for your computer.
After the loopback adapter is installed, there are at least two network adapters on your computer: your own network adapter and the loopback adapter. To run Oracle Database on Windows, set the loopback adapter as the primary adapter. You can change the bind order for the adapters without reinstalling the loopback adapter.
The bind order of the adapters to the protocol indicates the order in which the adapters are used. The local address is used for tools, such as Oracle Enterprise Manager. Any other applications that use a different Ethernet segment are routed to the network card. You are installing on a non-networked computer and plan to connect the computer to a network after installation. If there is a loopback adapter installed, you would see a section that lists the values for the loopback adapter.
