Currently you cannot use an in-memory mode on a server that is participating in a High Availability (aka HA or Mirroring) or a Scale Out configuration. The reason is that for both of these configurations the database must be actively using (writing / reading / transfering-to-remote server) a transaction log and the in-memory modes turn off these operations by design. See the -im switch in the 12.0.x docs for more information on what the in-memory modes are and what they do. We have discussed within SA engineering the possibility of using an in-memory mode in an HA or Scale Out configuration and will consider supporting this in some future release. |
