My VMware Cloud Team colleague Max Daneri of VMTS fame was building a vSphere 4.1 environment this week. During the installation of VUM(VMware Update Manager) he ran into an issue with the database connection which I thought would be useful to share with you. After some playing around he found out that apparently VUM requires a 32-bit ODBC DSN. Which was a surprise as VUM requires a 64-bit OS.
Of course we should have read the documentation first as it is stated on page 27 of the VUM Install Guide…
IMPORTANT: Although you can install the Update Manager server only on 64-bit machines, Update Manager is a 32-bit application and requires a 32-bit DSN.
