To resolve this issue, verify the Update Manager database settings.
To verify Update Manager database settings:
  1. Connect to vCenter Server.
  2. If you have created separate database for Update Manager, verify the ODBC connection at Start > Control Panel > Administrative Tools > Data Sources ODBC.
  3. Click the System DSN tab, click Configure and verify the user information for the Update Manager database.
  4. If you are using a remote SQL 2000 or 2005 database, verify that the Update Manager user has a default Update Manager database assigned. If not, assign a default Update Manager database to the Update Manager user.
  5. Verify the permissions for the user to access the Update Manager database on the remote SQL database machine.
  6. Re-login to vCenter Server through the vSphere Client and verify that Update Manager is working. If it does not work, reboot.
