Oracle on UNIX platform is a process based concept and on windows it is thread based concept. So kernel parameter provided by UNIX OS are not sufficient , setting of kernel parameter is required in case of UNIX whcih is not required in case of WINDOWS.

Oracle Server = Oracle Instance + Oracle Database Oracle instance comprises of Background Process and memory structures in Unix all background processes are treated as independent processes but in windows all are combined together within oracle.exe in unix when a user logins he is dedicated to the server via an independed process so if require you can kill a process through os level ..this is one of the major advantage of using oracle on unix based system rather then windows system bcoz in case database stucks or hangs an independent process causing the problem can be killed and database will be made resumable immediately.

and one more diffrence is in windows you are require to create a service to start the instance by using oradim but in unix its not required .you can start the instance.in windows unique service name is required but in unix diffrent user can have the same service name started by them but its not advisable.

1. installing oracle on Windows is piece of cake which requires less DBA intervention.

2. While installing Oracle on Linux is a laborious process which involves in
a. creating the groups (oinstall, oracle) required
b. creating the Oracle user who own the Oracle software directories and is a member of the groups previusly created.
c. Configuring Kernel parameters
d. Checking the network configuration.
e. configuring shell limits.
f.  Checking the  package requirements and installing the missing packages.
g. Creating the required mount points and fixing the ownership of all those mount points.

h. Fixing the environment variables of oracle user and installing oracle as Oracle user

Hi

I strongly feel, with OUI, installtion is more or less same on Windows and Unix.
there is nothing great about Unix installation.
