After you create and configure an Oracle database and user for vCenter Server, you must create a 64-bit DSN on the machine on which you plan to install vCenter Server. During the vCenter Server installation, you use the DSN to establish a connection between vCenter Server and the database.
- On the machine on which you plan to install vCenter Server, select .
- On the System DSN tab, modify an existing or create a new Oracle ODBC connection.
- To modify an existing Oracle ODBC connection, select the connection from the System Data Source list and click Configure.
- To create an Oracle ODBC connection, click Add, select the Oracle client, and click Finish.
- In the Data Source Name text box, enter an ODBC data source name (DSN).
For example, VMware vCenter Server.
- (Optional) In the Description text box, enter an ODBC DSN description.
- In the TNS Service Name text box, enter the net service name for the database to which you want to connect.
For example, VPX_TNS.
This is the net service name that you previously configured in the tnsnames.ora file that is located in the NETWORK\ADMIN folder in the Oracle database installation location.
- In the User ID text box, enter the database user name for vCenter Server.
For example, VPXADMIN.
- Click Test Connection.
- In the Password text box, enter the password of the database user and click OK.
If you configured the DNS correctly, the Connection successful message appears.
- Click OK.
