Oracle DB on VM

Assign different types of disks to separate paravirtualized SCSI controller.

Use EagerZeroedThick formatting on database disks to avoid performance penalty while zeroing during runtime.

Set VM property disk.EnableUUID to TRUE. Below PowerCLI code will do it

$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
$extra = New-Object Vmware.Vim.OptionValue
$extra.Key = "disk.EnableUUID"
$extra.Value = "true"
$vmConfigSpec.extraconfig = $extra

Get-VM | % { (Get-View $_.ID).ReconfigVM($vmConfigSpec)}
