Description

I have been extensively testing mirroring, and I'm hardening it as an overal task, improving its behavior:

• Page Transactions on mirror target are now optional.

• If you had an interrupt mirror while the target destination was paging, duplicate detection would be ineffective unless you used paged transactions
• Users can now configure the ack manager retries intervals.
  Say you need some time to remove a consumer from a target mirror. The delivering references would prevent acks from happening. You can allow bigger retry intervals and number of retries by tinkiering with ack manager retry parameters.
• The ackManager was only restarted when new acks were coming in. If you stopped receiving acks on a target server and restarted that server with pending acks, those acks would never be exercised. The AckManager retries are now restarted as soon as the server is started.
