Create A 32-Bit Dsn On A 64-Bit Operating System; Configure Vcenter Server To Communicate With The Local Database After Shortening The Computer Name To 15 Characters Or Fewer - VMware ESX 4.0 - INSTALLATION GUIDE UPDATE 1 Installation Manual

Create a 32-Bit DSN on a 64-Bit Operating System

You can install or upgrade to vCenter Server on both 32-bit and 64-bit operating systems.
Even though vCenter Server is supported on 64-bit operating systems, the vCenter Server system must have
a 32-bit DSN. This requirement applies to all supported databases. By default, any DSN created on a 64-bit
system is 64 bit.
Procedure
1 Install the ODBC drivers.
For Microsoft SQL Server and DB2 database servers, install the 64-bit database ODBC drivers on your
n
Microsoft Windows system. When you install the 64-bit drivers, the 32-bit drivers are installed
automatically.
For Oracle database servers, install the 32-bit database ODBC drivers on your Microsoft Windows
n
system.
N The default install location on 64-bit operating systems is
OTE
2 Run the 32-bit ODBC Administrator application, located at
3 Use the application to create your DSN.
You now have a DSN that is compatible with vCenter Server. When the vCenter Server installer prompts you
for a DSN, select the 32-bit DSN.
Configure vCenter Server to Communicate with the Local Database
After Shortening the Computer Name to 15 Characters or Fewer
The machine on which you install or upgrade to vCenter Server must have a computer name that is
15 characters or fewer. If your database is located on the same machine that vCenter Server will be installed
on and you have recently changed the name of this machine to comply with the name-length requirement,
make sure the vCenter Server DSN is configured to communicate with the new name of the machine.
Changing the vCenter Server computer name impacts database communication if the database server is on the
same computer with vCenter Server. If you have changed the machine name, verify that communication
remains intact by completing the following procedure.
The name change has no impact on communication with remote databases. You can skip this procedure if your
database is remote.
N The name-length limitation applies to the vCenter Server system. The data source name (DSN) and
OTE
remote database systems can have names with more than 15 characters.
Check with your database administrator or the database vendor to make sure all components of the database
are working after you rename the server.
Procedure
1 Make sure the database server is running.
2 Make sure that the vCenter Server computer name is updated in the domain name service (DNS).
One way to test this is by pinging the computer name. For example, if the computer name is
host-1.company.com
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.
