Setup
The Setup tab contains various setup options.
 Log Statistics Automatically—If enabled, Storage Mirroring statistics logging will start automatically when Storage
Mirroring is started.
 Enable Task Command Processing—Task command processing is a Storage Mirroring feature that allows you to insert
and run tasks at various points during the replication of data. Because the tasks are user-defined, you can achieve a wide
variety of goals with this feature. For example, you might insert a task to create a snapshot or run a backup on the target
after a certain segment of data from the source has been applied on the target. This allows you to coordinate a
point-in-time backup with real-time replication.
Task command processing can be enabled from the Management Console, but it can only be initiated through the
Storage Mirroring text clients or a DTCL script. See the Scripting Guide for more information.
If you disable this option on a source server, you can still submit tasks to be processed on a target, although task
command processing must be enabled on the target.
 Advertise service with Active Directory—If enabled, the Storage Mirroring service registers with Windows Active
Directory when the Storage Mirroring service is started.
 Automatically Reconnect During Source Initialization—If enabled, Storage Mirroring will automatically reconnect
any connections that it automatically disconnected.
 Perform Remirror After Auto-reconnect—If enabled, Storage Mirroring will automatically perform a remirror after
an auto-reconnect has occurred.
 Server Shutdown Timeout—This setting indicates the amount of time, in seconds, for the service to wait prior to
completing a shutdown so that Storage Mirroring can persist data on the target in an attempt to avoid a remirror when
the target comes back online. A timeout of zero (0) indicates waiting indefinitely and any other number indicates the
number of seconds. The timeout setting only controls the service shutdown from the Storage Mirroring clients. It does
not control the service shutdown through a reboot or from the Service Control Manager.
