Oracle RAC installations with VMWare and change block tracking
Are you plagued by that need for five 9's and have an Oracle RAC VM? Can't spare the time to shut down that VM? You don't need the Bass-o-matic 76 just the following to allow you to alter Change Block Tracking with an online VM. (Though a Bass-o-matic is highly recommended).
Just fetch your friendly PowerCLI interface to VMWare and connect to your friendly neighborhood vCenter:
$vm="VM_Name"
$vmtest = Get-vm $vm| get-view $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
