Before you install the Update Manager server, review the installation prerequisites.
Update Manager Database Requirements
Update Manager requires an Oracle or SQL Server database. Update Manager can handle small-scale environments using the bundled SQL Server 2008 R2 Express. For environments with more than 5 hosts and 50 virtual machines, you must create either an Oracle or SQL Server database. For large-scale environments, set up the database on a machine different than the machines on which the Update Manager server is installed and the vCenter Server database is located.
For more information about setting up the Update Manager database, see Preparing the Update Manager Database.
Create a database and 32-bit DSN, unless you are using the bundled SQL Server 2008 R2 Express.
Make sure that if the Update Manager database is located on a remote machine, the database and the system DSN use SQL Server authentication.
Update Manager does not support Windows authentication of the database when the database is located on a different machine because of local system account problems.
If you plan to use the bundled Microsoft SQL Server 2008 R2 Express database, make sure that you install Microsoft Windows Installer version 4.5 (MSI 4.5) on your system. You can download MSI 4.5 from the vSphere installer.
Make sure that the database privileges meet the requirements listed in Required Database Privileges.
Create the 32-bit ODBC connection to a supported database server version by using a supported database client version.
If you create an ODBC connection to a database server that is of an unsupported version, and your database client is of a supported version, a DSN for the unsupported database might be displayed in the drop-down menu of the Update Manager installation wizard.
vCenter Server Installation
Install vCenter Server.
If prompted, you must restart the machine on which vCenter Server is installed. Otherwise, you might not be able to register Update Manager with vCenter Server, and the Update Manager installation might fail.
For more information about installing vCenter Server, see vSphere Installation and Setup.
Gather the following networking information for the vCenter Server system.
User name and password for the vCenter Server system.
During the Update Manager installation process, you must register the Update Manager server with the vCenter Server system. To register Update Manager with vCenter Server, you must provide the credentials of the vCenter Server user that has the Register extension privilege. For more information about managing users, groups, roles, and permissions, see vCenter Server and Host Management.
Port numbers. In most cases, the default Web service port 80 is used.
If the IP address of the vCenter Server system or Update Manager changes, you can re-register the Update Manager server with the vCenter Server system. For more information about configuring the Update Manager server after installation, see Reconfiguring VMware vSphere Update Manager.
Update Manager System Requirements
Make sure that your system meets the requirements specified in System Requirements.Important:
You can install the Update Manager 5.5 server component only on a 64-bit machine. Make sure the system on which you are installing the Update Manager server is not an Active Directory domain controller.
Log in as a local Administrator or a domain user that is member of the Administrators group.
