Restoring involves extracting data from a backup and then applying logged transactions to that data to bring it forward to the target recovery point. If a problem occurs with the restore sequence for example, a database administrator overshoots the intended recovery point it is necessary to restart the restore sequence from the very beginning. Restoration involves three distinct phases: the data copy phase, redo phase, and undo phase. During the data copy phase, data, log, and index pages are copied from the backup media to the database. During the redo phase, logged transactions are applied to the database. During the undo phase, uncommitted transactions are identified and rolled back to bring the database to a consistent state. File restores enable restoration of one or more damaged files without requiring the restoration of the entire database. Page restores are used when a small number of pages have been damaged. Restoring several individual pages is often faster than performing a file restore. A database snapshot is a read-only static view of a database as it existed when the snapshot was created. You can store multiple snapshots of a database, and snapshots persist until dropped. You can query a database snapshot. You can revert the database to the state it was in when the snapshot was taken. You can bulk copy data from the snapshot into the database and then manually merge it. Snapshots cannot be backed up or restored, nor attached or detached. An orphaned user is a database user for which the SQL Server login is undefined. The sp_change_users_login stored procedure can be used to re-link orphaned users who use SQL Server 2005 authentication, but not users who use Windows for authentication.

Distributor The machine that distributes data. The Distributor makes the publication available to the Subscriber. It creates tables and files to store the data it replicates, and you need to choose a machine that has sufficient disk space to do so. Optionally, you can configure a Distributor to store a snapshot replication file

When you select Disk Management on Node2, the Initialize And Convert Disk Wizard does not appear because the disks already have a signature written to them. You do not need to format the disks because you already performed this step when you configured Node1. You also do not need to specify drive letters because Node2 picks them up from the cluster after you configure it. Table 8-10 Node2 Disk Configuration

William Ryan Many people are intimidated by threading and asynchronous invocation. How ever, the difference between applications that users enjoy and ones that anger users is often asynchronous invocation. In the previous Real World example, I spoke of our move to Web services. In the beginning we had a few problems. We typically built customized client applications and used standard invocations. However, the Web isn t always stable and available, so our applications would often freeze up while waiting for methods to return. Fortunately, changing from a synchronous application model to an asynchronous application model was very simple. Using asynchronous delegates made everything a lot easier, and, fortunately, it was an easy port in most cases.
