VMware recommends that the vCenter Server database be located on the same system as vCenter Server.

Before configuring an Oracle connection, review the required database patches specified in vCenter Server Database Patch and Configuration Requirements. If you do not prepare your database correctly, the vCenter Server installer displays error and warning messages.


Download Oracle 10g or Oracle 11g from the Oracle Web site, install it, and create a database.


Configure the TNS Service Name option in the ODBC DSN.

The TNS Service Name is the net service name for the database to which you want to connect. You can find the net service name in the tnsnames.ora file located in the NETWORK\ADMIN folder in the Oracle database installation location.
