2 Oracle Database Companion CD Requirements

2.3.1.1 Oracle Database Requirement

Oracle HTTP Server must have access to Oracle Database release 1 (10.1) or Oracle9i release 9.2.0.3 in order to run. Oracle Database can be on a separate system from Oracle HTTP Server, as long as it is accessible by Oracle*Net. However, Oracle HTTP Server must be in its own home.

For example, if Oracle Database has been installed in OraDB10g_home1, when you run Oracle Universal Installer to install Oracle HTTP Server, you can specify the Oracle Database in that home, but you need to install Oracle HTTP Server into its own home, for example, OraDB10g_home2.

2.3.1.2 Hardware Requirements

Oracle HTTP Server must meet the following hardware requirements for NTFS systems:

• Physical RAM: Minimum size 256 MB, recommended 512 MB

• Virtual Memory: Double the RAM

• Temp directory: 100 MB of disk space

• Disk space for Companion CD products:

  Products for Installation	System Drive Disk Space	Oracle Home Disk Space
  Oracle HTTP Server	80 MB	162 MB
  Oracle HTTP Server and Oracle HTML DB	100 MB	535 MB

  
  

For FAT 32 systems, use slightly higher settings.

2.3.1.3 Operating System and Service Pack Requirements

Oracle HTTP Server has the following minimum operating system and service pack requirements:

• Windows NT Server 4.0 with service pack 6a or higher

  Windows NT includes: Windows NT Server 4.0, Windows Server Enterprise Edition 4.0, and Terminal Server Edition

• Windows 2000 with Service Pack 3 or higher

  Windows 2000 includes: Window 2000 Professional, Windows 20000 Server, Windows 200 Advanced Server, Windows 2000 Datacenter Server, and Terminal Services

• Windows Server 2003

• Windows XP Professional: supported for Oracle HTTP Server

2.3.2.1 Oracle Database Requirement

Oracle HTML DB requires either Oracle Database release 1 (10.1) or Oracle9i release 9.2.0.3. You need to install Oracle HTML DB into an Oracle home that contains Oracle HTTP Server. (This home, with both Oracle HTML DB and Oracle HTTP Server, is referred to as the Companion CD Oracle home.) The Companion CD Oracle home can be on a different physical server from the Oracle Database home, as long as Oracle HTML DB can access this database with Oracle*Net.

For example, if Oracle Database has been installed in OraDB10g_home1, when you run Oracle Universal Installer to install Oracle HTML DB, you can specify the Oracle Database in that home, but you need to install Oracle HTML DB into its own home that contains Oracle HTTP Server, for example, OraDB10g_home2.

2.3.2.2 Disk Space Requirements

Verify that the file system that contains the Oracle home directory contains at least 460 MB of free disk space for the installation. The system drive disk space requirement is 100 MB.

2.3.2.3 Oracle HTTP Server Requirement

Oracle HTML DB must have access to Oracle HTTP Server in order to run. If you plan to install Oracle HTML DB into an existing Oracle home, check that the system has an Oracle home directory that contains Oracle HTTP Server release 9.0.4 or higher with mod_plsql. Oracle home directories for the following products meet this requirement:

• Oracle HTTP Server 10g

• Oracle Identity Management 10g (part of Oracle Application Server 10g)

If the system does not meet these requirements, you will need to install Oracle HTTP Server 10g when you install the Oracle Database 10g Companion Products.

2.3.2.4 Oracle XML DB Requirement

Oracle XML DB first must be installed in the Oracle database that you want to use. If you are using a preconfigured database created either during an installation or by Database Configuration Assistant (DBCA), Oracle XML DB is already installed and configured.

2.4.4.1 Checking if a Loopback Adapter Is Installed on Your Computer

To check if a loopback adapter is installed on your computer, run the ipconfig /all command:

prompt> ipconfig /all

If there is a loopback adapter installed, you would see a section that lists the values for the loopback adapter. For example:

Ethernet adapter Local Area Connection 2:
  Connection-specific DNS Suffix  . :
  Description . . . . . . . . . . . : Microsoft Loopback Adapter
  Physical Address. . . . . . . . . : 02-00-4C-4F-4F-50
  DHCP Enabled. . . . . . . . . . . : Yes
  Autoconfiguration Enabled . . . . : Yes
  Autoconfiguration IP Address. . . : 169.254.25.129
  Subnet Mask . . . . . . . . . . . : 255.255.0.0

2.4.4.2 Installing a Loopback Adapter on Windows NT

Installing a loopback adapter on Windows NT is more complicated than on other Windows platforms because Windows NT reports on the first network adapter installed. Since your DHCP computer already has a network adapter, you need to remove it and reinstall it later so that the loopback adapter becomes the first network adapter installed. This section describes how to do this in these subsections:

• "High-Level Steps"

• "Requirements"

• "Detailed Steps"

High-Level Steps

The high-level steps to install a loopback adapter on Windows NT are:

1. Collect information for the existing network adapter on your computer.

   You need to perform this step because you must remove the existing network adapter and reinstall it.

2. Install the loopback adapter.

3. Remove the existing network adapter.

4. Finish configuring the loopback adapter.

5. Restart the computer.

6. Reinstall the network adapter.

7. Restart the computer.

Requirements

To install a loopback adapter on Windows NT, you need the following items:

• Windows NT Installation CD-ROM, so you can can install the loopback adapter

• Drivers for your network adapters when you reinstall the network adapters.

Detailed Steps

1. Collect information for your existing network adapter so that you can reinstall it. Typically you need the following pieces of information:

   Table 2-1 Information for Your Existing Network Adapter

   Item	Where to Get Its Value
   IP address	Network control panel, Adapter tab. Select the network adapter, then click Properties.
   Subnet mask	Network control panel, Protocols tab. Select TCP/IP, then click Properties. In the Properties dialog, select the IP Address tab and click Advanced.
   WINS Server address	Network control panel, Protocols tab. Select TCP/IP, then click Properties. In the Properties dialog, select the WINS Address tab.
   DNS Server address	Network control panel, Protocols tab. Select TCP/IP, then click Properties. In the Properties dialog, select the DNS tab.

   
   

2. Insert the Windows NT Installation CD-ROM in the CD-ROM drive.

3. Right-click Network Neighborhood on the desktop, and choose Properties. This displays the Network control panel.

4. Select the Adapters tab.

5. Click Add.

6. Select MS Loopback Adapter and click OK.

7. In the MS Loopback Adapter Card Setup dialog, click OK to accept the default frame type (the default value is 802.3).

8. Enter the location of your Windows NT CD-ROM (for example, E:\i386) and click Continue.

   When the loopback adapter is installed, Windows NT displays the Network control panel showing all the network adapters (Figure 2-1).

   Figure 2-1 Network Control Panel Showing the Loopback Adapter

   
   Description of the illustration network_nt.gif
   
   

9. In the Network control panel, delete the network adapters that were installed before the loopback adapter. Select the network adapter and click Remove.

   You need to do this because you want the loopback adapter to be the first network adapter. In the example, you would delete the Intel network adapter. You will reinstall it later.

10. Click Close in the Network control panel. This displays the Microsoft TCP/IP Properties dialog (Figure 2-2).

11. In the Microsoft TCP/IP Properties dialog, select MS Loopback Adapter, and do the following:

    1. IP Address: Enter a non-routable IP for the loopback adapter. Oracle recommends the following non-routable addresses:

       • 192.168.x.x (x is any value between 1 and 255)

       • 10.10.10.10

    2. Subnet mask: Enter 255.255.255.0.

    3. Leave all other fields empty.

    4. Click OK.

12. Restart your computer.

13. When the computer comes back up, reinstall your real network adapter.

14. Restart the computer again.

2.4.4.3 Installing a Loopback Adapter on Windows 2000

Windows 2000 reports on the last network adapter installed. This means that if you install additional network adapters after you install the loopback adapter, you need to remove and reinstall the loopback adapter. The loopback adapter must be the last network adapter installed on the computer.
