2.1 Becoming Familiar with the Features of Oracle Audit Vault

To plan the installation process, you must be familiar with the features of Oracle Audit Vault. Oracle Audit Vault Administrator's Guide discusses the basic features of Oracle Audit Vault.

2.2 Checking the Hardware Requirements

Table 2-1 lists the required hardware components for Oracle Audit Vault Server.

Table 2-1 Hardware Requirements

Requirement	Minimum Value
Physical memory (RAM)	512 MB
Virtual memory	Double the amount of RAM
Hard disk space	2.02 GB Total See Table 2-2 for details.
Video adapter	256 colors
Processor	550 MHz minimum

2.2.1 Hard Disk Space Requirements

This section lists system requirements for Windows platforms that use the NT File System (NTFS) file systems. FAT32 space requirements are slightly larger. Oracle recommends installing Oracle components on NTFS.

The NTFS system requirements listed in this section are more accurate than the hard disk values reported by the Oracle Universal Installer Summary window. The Summary window does not include the space required to create a database or the size of compressed files that are expanded on the hard drive.

The hard disk requirements for Oracle Database Client components include space required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, then installation fails and an error message appears.

Table 2-2 lists the space requirements for NTFS.

Table 2-2 Disk Space Requirements for NTFS

TEMP Space	Oracle Home	Data Files	Total
44 MB	0.976 GB	1.0 GB	2.02 GB

See Also:

"NTFS File System and Windows Registry Permissions" in Oracle Database Platform Guide for Microsoft Windows (32-Bit)

The 0.976 GB of disk space for the Oracle home is the disk space for the Oracle Audit Vault Server software files in the Oracle Base. The TEMP space required is 44 MB.

The 1.0 GB of disk space for the Audit Vault database files is only if the database storage option is on the file system. For other storage options, such as ASM, the database files will be stored elsewhere. Also, this 1.0 GB disk space is only the starting size. The Audit Vault administrator must take future growth of the database size into consideration, especially as the server collects more and more audit data.

To ensure that the system meets these requirements, perform the following tasks:

1. Determine the physical RAM size. For a computer using Windows 2003, for example, open System in the Windows Control Panel and select the General tab. If the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.

2. Determine the size of the configured virtual memory (also known as paging file size). For a computer using Windows 2003, for example, open System in the Control Panel, select the Advanced tab, and click Settings in the Performance section. Then select the Advanced tab. The virtual memory is listed in the Virtual Memory section.

   If necessary, see your operating system documentation for information about how to configure additional virtual memory.

3. Determine the amount of free disk space on the system. For a computer using Windows 2003, for example, open My Computer, right-click the drive where the Oracle software is to be installed, and choose Properties.

4. Determine the amount of disk space available in the temp directory. This is equivalent to the total amount of free disk space, minus what will be needed for the Oracle software to be installed.

   If there is less than 100 MB of disk space available in the temp directory, then first delete all unnecessary files. If the temp disk space is still less than 100 MB, then set the TEMP or TMP environment variable to point to a different hard drive. For a computer using Windows 2003, for example, open System in the Control Panel, select the Advanced tab, and click Environment Variables.

2.3 Checking the Operating System Requirements

Table 2-3 lists the software requirements for Oracle Audit Vault Server.

Note:

Oracle Universal Installer performs checks on your system to verify that it meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer.

2.5 Checking the Network Setup

Typically, the computer on which you want to install Oracle Audit Vault Server is connected to the network, has local storage to contain the Oracle Audit Vault Server installation, has a display monitor, and has a CD-ROM or DVD drive.

This section describes how to install Oracle Audit Vault on computers that do not meet the typical scenario. It covers the following cases:

• Installing on DHCP Computers

• Installing on Computers with Multiple Homes

• Installing on Computers with Multiple Aliases

2.5.1 Installing on DHCP Computers

dynamic host configuration protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing enables a computer to have a different IP address each time it connects to the network. In some cases, the IP address can change while the computer is still connected. You can have a mixture of static and dynamic IP addressing in a DHCP system.

In a DHCP setup, the software tracks IP addresses, which simplifies network administration. This lets you add a new computer to the network without having to manually assign that computer a unique IP address.

Audit Vault Server cannot be installed in an environment where the IP addresses of the Audit Vault Server or the Audit Vault Agent can change. If your environment uses DHCP, ensure that all Audit Vault systems use static IP addresses.

2.5.2 Installing on Computers with Multiple Homes

You can install Oracle Audit Vault on a computer that has multiple homes. A multiple-homed computer is associated with multiple IP addresses. This is typically achieved by having multiple network cards on the computer. Each IP address is associated with a host name. In addition, you can set up aliases for the host name. By default, Oracle Universal Installer uses the ORACLE_HOSTNAME environment variable setting to find the host name. If the ORACLE_HOSTNAME environment variable is not set and you are installing Oracle Audit Vault on a computer that has multiple network cards, then Oracle Universal Installer determines the host name by using the first entry in the hosts file, typically located in SYSTEM_DRIVE:\WINDOWS\system32\drivers\etc on Windows 2003 and Windows XP, or on Windows 2000 SYSTEM_DRIVE:\WINNIT\system32\drivers\etc.

Clients must be able to access the computer either by using this host name or by using aliases for this host name. To verify this, ping the host name from the client computers using the short name (host name only) and the full name (host name and domain name). Both tests must be successful.

Setting the ORACLE_HOSTNAME Environment Variable

To set the ORACLE_HOSTNAME environment variable:

1. Display System in the Windows Control Panel.

2. In the System Properties dialog box, click Advanced.

3. In the Advanced tab, click Environment Variables.

4. In the Environment Variables dialog box, under System Variables, click New.

5. In the New System Variable dialog box, enter the following information:

   • Variable name: ORACLE_HOSTNAME

   • Variable value: The host name of the computer that you want to use.

6. Click OK, then in the Environment Variables dialog box, click OK.

7. Click OK in the Environment Variables dialog box, then in the System Properties dialog box, click OK.

2.5.3 Installing on Computers with Multiple Aliases

A computer with multiple aliases is registered with the naming service under a single IP address. The naming service resolves all of those aliases to the same computer. Before installing Oracle Audit Vault on a computer with multiple aliases, set the ORACLE_HOSTNAME environment variable to the computer whose host name you want to use.

2.6 Creating Directories for Oracle Audit Vault Database Files

If you choose to place the Oracle Audit Vault database files on a file system, then use the following guidelines when deciding where to place them:

• The default path suggested by Oracle Universal Installer for the database file directory is a subdirectory of the Oracle base directory.

• You can choose either a single file system or more than one file system to store the database files:

  • If you want to use a single file system, then choose a file system on a physical device that is dedicated to the database.

    For best performance and reliability, choose a RAID device or a logical volume on more than one physical device and implement the stripe-and-mirror-everything (SAME) methodology.

  • If you want to use more than one file system, then choose file systems on separate physical devices that are dedicated to the database.

    This method enables you to distribute physical I/O and create separate control files on different devices for increased reliability. It also enables you to fully implement the OFA guidelines.

• For optimum performance, the file systems that you choose should be on physical devices that are used only by the database.

• The user with Administrators privilege or who is a member of the ORA_DBA group performing the installation has write permissions to create the files in the path that you specify.

2.7 Setting the System Time Zone to GMT 00:00

Before installing Oracle Audit Vault Server on Windows (32-bit), you must make sure the system time zone is set with its original value of GMT 00:00. Setting the time zone to its original value will allow Oracle Universal Installer to automatically set the agentTZRegion property in the emd.properties file to its correct timezone value for the geographical location of the system during the installation. This will then allow the Audit Vault Console to show correct data on the Overview page. To perform this task, follow this procedure:

1. Change the Windows system time to GMT 00:00 using the Control Panel -> Date and Time -> Time Zone tab -> select the (GMT) Greenwich Mean Time: Dublin, Edinburgh, Lisbon, London option, click Apply, then click OK.

2. Install Oracle Audit Vault Server.

Note:

If Oracle Enterprise Manager has an issue with the time zone, then see Section 10.1.5 "Setting the Management Agent Time Zone" in Oracle Enterprise Manager Advanced Configuration as a workaround. After performing the Oracle Enterprise Manager workaround, restart Oracle Enterprise Manager.
