Subject Re: transaction log directory on VM
Date Thu, 25 Jan 2018 16:08:45 GMT
Hi Kathryn,

The only benefit I can think of is that transaction logs cannot steal space
from other parts of the system. e.g. root filesystem
Other than that it should be on a physically different drive for
performance gain.
