Oracle 9i App Server Deinstall

Question

Does anyone have a clue on how to deinstall Oracle 9i Application Server?
In the documentation, i didn't find a mention of deleting the respective directories/files and it's corresponding registry entries. Any help on this is appreciated.
Thanks much,
Raj

Deinstalling the Software
How to Deinstall All Oracle Software
1. If you have already installed Oracle software, use Oracle Database Configuration Assistant to delete all current instances. Make sure that the necessary services are started in Control Panel Services before doing this.
2. Stop all Oracle-related services in the Services control panel.
3. Deinstall all Oracle products, using the appropriate installers.
4. Delete all Oracle software directories, including the inventory files in the C:\PROGRAM FILES\ORACLE directory.
How to Uninstall Additional Software
1. Deinstall the following additional software:
JDeveloper
Apache
JDK
2. In addition, delete your SCTW directory if you have already taken any of the courses in this series.
Checking the Registry
How to Check Registry Entries
1. Select Start > Run, enter REGEDIT, and click OK.
2. At the Windows NT Registry Editor, expand the HKEY_LOCAL_MACHINE\SOFTWARE registry item.
3. Delete the ORACLE key.
4. Expand the HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services registry item.
5. Delete all keys that begin with ORACLE.
6. Expand the HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\EventLog\
Application registry item.
7. Delete all keys that begin with ORACLE.
8. Repeat steps 5 through 8 for any other ControlSet references in your register that contain ORACLE keys.
Checking Environment Variables
How to Check Environment Variables
1. Select Start > Settings > Control Panel and double-click System.
2. Delete all Oracle-related environment variables (especially any ORACLE_HOME variables).
3. Delete all Oracle-related paths from the PATH variable.
4. Delete any reference to the JDK directory from the PATH variable.
Checking Virtual Memory
How to Check Virtual Memory
1. Select Start > Settings > Control Panel and double-click System.
2. Click the Performance tab and then click the Change button to open the Virtual Memory window.
3. You need approximately 512 MB of total memory (256 MB of RAM and 256 MB of virtual memory). However, if you have enough disk space, set virtual memory to 500 MB. Click the Set button. Then click OK.
Reconfiguring TCP/IP Services
How to Reconfigure TCP/IP Services
You must also make sure that the networking structure is set up correctly for installation off the network. If you are using DHCP to provide you with an IP address, you need to set up a static IP address for this example.
1. Select Start > Settings > Control Panel.
2. Double-click Network.
3. Click the Protocols tab.
4. Select TCP/IP Protocol and then click the Properties button.
5. Select Specify an IP address.
6. Enter a valid IP address, subnet mask, and default gateway. If you do not have an IP address, enter a dummy value. Click OK twice.
Note: the Enterprise Manager OMS and Agent do not support DHCP so you need to have a static IP address to use this capability.

Other Cleanup Tasks
1. You also need to set up your environment so that the local host name can be resolved without the need to look up DNS. To do this, edit the C:\WINNT\System32\Drivers\Etc\Hosts file. Add the IP address and fully qualified host name for your computer after the localhost line currently in the file. Save your work and close the file.
2. If you have taken a previous version of this class before, you must remove your NTOEM user from User Manager.
3. Reboot your machine.
