[Oracle] Loopback Adapters for Oracle Installation in DHCP Networks

Loopback Adapters for Oracle Installation in DHCP Networks
DHCP 서버로부터 IP 주소를 임대하여 사용하는 서버에 Oracle10g를 설치하는 경우, 설치 중간에 경고 메시지가 발생하거나 일부 구성요소들의 설치가 실패 할 수도 있다. (DHCP 서버를 사용하고 있다면 '네트워크 구성 요구 사항을 확인 하는 중' 항목에 경고 표시가 뜸) 이런 경우는 Oracle10g를 설치하기 전에 Loopback Adapter를 설치하면 Oracle10g의 설치 과정에서 경고 메시지가 발생하지 않도록 할 수 있다.
#1 cmd에서 ipconfig /all을 실행하여 DHCP 서버를 사용중인지 확인한다
NIC
DHCP Enabled ... : Yes 인지 확인
#2 DHCP서버를 사용하고 있는지를 확인하여 사용하고 있을 시 "Microsoft Loopback Adapter"를 설치한다
A. 제어판 ->하드웨어 추가 ->목록에서 직접선택 ->네트워크 어댑터 선택 ->Microsoft ->Loopback Adaptoer
B. cmd에서 hdwwiz.exe
#3 설치하면 Network가 하나 더 생긴다 TCP/IP 선택하고 IP 주소를 다음과 같이 설정한다.
- Microsoft Loopback Adapter 설치 (192.168.X.X, 255.255.255.0, no gateway)
#4 hosts파일 수정 Loopback IP 등록 (XP에서는 필수) c:/windows/systmes32/drivers/etc/hosts
127.0.0.1 localhost
192.168.X.X hostname domainName
* 예 192.168.10.10 ken ken
* hostname 확인은 cmd에서 hostname을 치면 나온다
#5 Oracle10g를 설치한다
# Loopback Adapters for Oracle Installation in DHCP Networks
Dynamic Host Configuration Protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing allows 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. However, before installing Oracle Database onto a computer that uses the DHCP protocol, you need to install a loopback adapter to assign a local IP address to that computer.
Loopback adapter approach is recommended particularly for laptops (presumably used only for learning purposes!) which connect and disconnect from the real, corporate network. The loopback adapter means that Oracle will function regardless of whether the laptop is connected to the network or not: it gives Oracle a static, always-there, point of reference independent of what shenannigans the real NIC gets up to.
To install a loopback adapter on Windows XP:
1. From the Start menu, select Control Panel.
2. Double-click Add Hardware to start the Add Hardware wizard.
3. On the Welcome screen, click Next.
4. On the Is the hardware connected? screen, select Yes, I have already connected the hardware, and click Next.
5. On the The following hardware is already installed on your computer screen, select Add a new hardware device, and click Next.
6. On the The wizard can help you install other hardware screen, select Install the hardware that I manually select from a list, and click Next.
7. From the list, select the type of hardware you are installing screen, select Network adapters, and click Next.
8. On the Select Network Adapter screen, make the following selections: * Manufacturer: select Microsoft. * Network Adapter: select Microsoft Loopback Adapter.
9. Click Next.
10. On the The wizard is ready to install your hardware screen, click Next.
11. On the Completing the Add Hardware Wizard screen, click Finish.
12. If you are using Windows 2003, restart your computer.
13. Right-click My Network Places on the desktop and choose Properties. This displays the Network Connections control panel.
14. Right-click the connection that was just created. This is usually named "Local Area Connection 2". Choose Properties.
15. On the General tab, select Internet Protocol (TCP/IP), and click Properties.
16. In the Properties dialog, 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.
17. Click OK.
18. Click OK in the Local Area Connection 2 Properties dialog.
19. Restart the computer.
20. Add a line to the C:\windows\system32\drivers\etc\hosts file with the following format, after the localhost line: IP_address hostname.domainname hostname where:
* IP_address is the non-routable IP address you entered in step 16.
* hostname is the name of the computer.
* domainname is the name of the domain.
For example: 10.10.10.10 mycomputer.mydomain.com mycomputer
21. Check the network configuration:
1. Open System Properties, and select the Computer Name tab. In Full computer name, make sure you see the hostname and the domain name.
2. Click Change. In Computer name, you should see the hostname, and in Full computer name, you should see the hostname and domain name.
3. Click More. In Primary DNS suffix of this computer, you should see the domain name.
