Before a vCenter Server system can access the Oracle database remotely, you must configure an Oracle connection.

Review the required database patches specified in vCenter Server Database Configuration Notes. If you do not prepare your database correctly, the vCenter Server installer displays error and warning messages.

1

Install the Oracle client on the vCenter Server system machine.

2

Download and install the ODBC driver.

3

Create a new tablespace for a vCenter Server system using a SQL statement such as the following statement.

CREATE TABLESPACE "VPX" DATAFILE 'C:\Oracle\ORADATA\VPX\VPX.dat' SIZE 1000M AUTOEXTEND ON NEXT 500K;
4

Create a user, such as vpxAdmin, for accessing the tablespace through ODBC.

CREATE USER vpxAdmin IDENTIFIED BY vpxadmin DEFAULT TABLESPACE vpx;
5

Grant permissions to the user, in one of the following ways.

Grant dba permission to the user.

Grant the following permissions to the user.

grant connect to user
grant resource to user
grant create view to user
grant create sequence to user
grant create table to user
grant create materialized view to user
grant execute on dbms_lock to user
grant execute on dbms_job to user
grant unlimited tablespace to user # To ensure space is sufficient

By default, the RESOURCE role has the CREATE PROCEDURE, CREATE TABLE, and CREATE SEQUENCE privileges assigned. If the RESOURCE role lacks these privileges, grant them to the vCenter Server database user.

6

Use a text editor or the Net8 Configuration Assistant to edit the tnsnames.ora file located in the directory C:\Oracle\Oraxx\NETWORK\ADMIN, where xx is either 10g or 11g.

Add the following entry, where HOST is the managed host to which the client must connect.

VPX =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP)(HOST=vpxd-Oracle)(PORT=1521))
   )
(CONNECT_DATA =
(SERVICE_NAME = VPX)
   )
   )
7

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, in this case, VPX. You can find the net service name in the tnsnames.ora file.
