When the server processes objects, it raises trace events to which client applications can subscribe to see progress reports. The Process Progress dialog box listens to these events and shows the progress of the processing operation. You can see which objects are being processed in parallel, the duration of the processing job, the SQL SELECT statement that the server sends to the data source to load data, and the number of rows retrieved, as Figure 7-26 shows. In the case of an error, the Process Progress dialog box shows the error message.

Once the file has been set up, an event handler needs to be defined. This event handler will be notified when the config file is changed. Within the event handler, the RefreshSection method on System.Configuration.ConfigurationManager is used to mark the section so that it is reread from disk the next time it is accessed.

A little more than two years ago, we were at a customer site to help implement clustering. Instead of starting with the installation and configuration of cluster ing, we had to back up and explain clustering. Some consultant told employees of this company that clustering could be used to eliminate downtime when ser vice packs were installed and enable them to load-balance their hardware resources. They were also told that clustering could enable a transaction that started on one node to be completed after the cluster failed over. Clustering does not have the capability to do any of these things. SQL Server failover clustering provides protection against hardware failures. In the event of a failure of one piece of hardware, a second piece of hardware automatically takes over and starts up SQL Server. Service packs still cause an outage on a cluster because the SQL Server instance can exist on only a single node at any time. Any transactions that are not completed when a cluster fails over are rolled back. Because SQL Server does not allow multiple processes to simultaneously access database files, load balancing is not possible. After explaining that clustering only protects from hardware failures, we still implemented the cluster within the customer s environment. The customer could effectively manage the database within the cluster by understanding that failures would still incur outages, but the amount of downtime because of hard ware failure would be minimal.

Authentication is the validation of the credentials, such as a name and password, a user gives to a remote access server. Authorization is the verification that the authenticated individual does indeed have permission to use the resource he or she is attempting to access.

Suppose that you have a Customer dimension that includes a Phone number attribute that stores customers phone numbers. It is unlikely that end users will group data by the Phone number attribute. So you can set this attribute s Aggregationusage property to none to instruct the Aggregation Design Wizard not to consider the Phone number attribute when designing aggregations.

To illustrate the usefulness of DTUtil for SSIS management and operations, we will look at a few common examples. In the first example, shown here, the DTUtil operation copies a file named MyPackage.dtsx from a local folder to the same local folder with the new file name MyCopiedPackage.dtsx. (Note that parentheses are needed if any spaces exist in the path.)
