Thanks for quick response, As I am not good into oracle administration can you provide me step by step.
You need read teamcenter documentation - server installation guide for example. If there is no helpfull information about oracle DB creation I would recommended to find corresponding training - Teamcenter Installation, wich have to include oracle database intallations steps for TC environment
Just log into to your Oracle database using some clients (SQL Developer, Toad, etc.). Create a user in that database. Launch tem.bat and in the screen to populate database, select the option - database exists and need to populate it. In the dialog, give the user name schema) you had created earlier and keep going ahead. This will install Teamcenter schema under this Oracle user.
Hope this helps!!!
