.. Copy only the install directory from the CD to the hard disk ,say, e:\temp. 
b. Open oraparam.ini and make the following modifications (Assuming CD drive is f:) 
* Change the "SOURCE=" line to use the full path to the CD instead of a 
relative path. (i.e., SOURCE=f:\stage\products.jar) 
* Change the "JRE_LOCATION" line to use the full path to the CD instead of 
a relative path. (i.e., 
JRE_LOCATION=f:\stage\Components\oracle\swd\jre\1.1.7\1\DataFiles\Expanded)
* Change the "OUI_LOCATION" line to use the full path to the CD instead of a 
relative path. (i.e., 
OUI_LOCATION=f:\stage\Components\oracle\swd\oui\1.6.0.9.0\1\DataFiles\Expanded
* Change the "JRE_MEMORY_OPTIONS" line to add "-nojit" as the first argument. 
(i.e., JRE_MEMORY_OPTIONS=-nojit -ms16m -mx32m) 
^^^^^^ 
* Other entries should remain the same 
c. Launch setup.exe from the temporary location on your hard drive (i.e. 
e:\temp\install\win32\setup.exe). This will use the modified 
oraparam.ini and pick up the information from the CD since the absolute 
locations are specified. 
Choose a Custom install and choose not to create a database during the 
install. This way, the Database Configuration Assistant will not be launched  
during installation. 
The Net8 Configuration Assistant will still be launched, and there is no way 
to suppress it. You will need to kill the Net8 Configuration Assistant if it 
hangs due to the bug. The installation still will have been successful, and 
you can run the DBCA and NetCA after installation. 
To kill NetCA if it hangs during installation: 
In the "Configuration Tools" window, highlight the "Net8 Configuration 
Assistant" and click "Stop". If that does not work, look for the most recent 
JRE process using the Task Manager, and kill it manually. NOTE: the OUI 
itself will also have a jre process. Be sure to kill the one with the most 
recent date, which should be the jre process being used for Net8CA, not the 
one for OUI itself. 
After killing the configuration tools and continuing through the installation 
to the "End of Installation" screen, you should modify the configuration tools 
to use "-nojit", then call the appropriate tools from the Start Menu. 
Once installation is complete, each of the following files in the ORACLE_HOME 
needs to be modified: 
assistants\dbca\dbassist.cl 
assistants\dbma\dbmig.cl 
assistants\ifa\ifa.cl 
bin\elogin.cl 
bin\owm.cl 
ldap\oidamdin\oidadmin.cl 
network\tools\netasst.cl 
network\tools\netca.cl 
owm\install\instelogin.cl 
owm\install\instowm.cl 
Edit the contents of the above files to add "-nojit" as shown below: 
Command=("C:\Program Files\Oracle\jre\1.1.7\BIN\JREW" -nojit -classpath ....  
this is the only thing you need to add --> ^^^^^^
