Media libraries Encompass both online libraries and offline media physical locations. Online libraries, which include robotic libraries and stand-alone drives, are data-storage devices that provide a method of reading and writing to media when necessary. Offline media physical locations are holding places for media units that are cataloged by Removable Storage, but are not currently immediately available through an online library. Work queues Hold library requests until resources become available. For example, a robotic tape library has a fixed number of tape drives to access media. A request submitted to the library is held in a work queue until a tape drive becomes available and the requested tape is mounted. Operator (administrator) requests Hold requests for offline media. The operator must make the media available before processing can continue. Other situations that generate operator requests include the failure of a device or a device needing to be cleaned when no cleaner cartridge is available. After a request is satisfied, the administrator must inform Removable Storage so that processing can continue.

A partition scheme, which provides an alternate definition for storage, is defined to encompass one or more filegroups. An example of a partition scheme is as follows:

SELECT * FROM Credit;

approve the session. The only people who can forcibly disconnect you from a remote desktop are the ones who would be able to log you off if you d left your screen locked normally.

Third query filter; only supports filtering on the results of aggregate functions Determines which columns should be returned by the query Result sorting Fourth (and last) query filter; causes the query to return only the first X rows from the previous clause Converts the tabular result returned by the SELECT statement to XML

Figure 6-35: The Advanced Sharing Settings dialog box Typically, other computers on a small wired network connect to the Internet through the first computer that you configure on the network To enable this to happen, you need to configure ICS on that computer You Configured an ICS computer and an ICS client in Exercise 2, "ConfiguringICS on the Canberra Computer," in Lesson 1 When you enable ICS, your LAN connection is Configured with a new static IP address (19216801) and other settings (for example, subnet mask, default gateway, and DNS server address) The static address (192 16801) is used as the default gateway for the subnet If you connect other computers to your network before you enable ICS, you might need to change their TCP/IP settings, typically by rebooting.

After this lesson, you will be able to: Recognize what bad exception handling looks like. Identify the purpose of good exception handling. Construct a mechanism to handle exceptions that are not anticipated by the application. Estimated lesson time: 40 minutes

As a general rule, it is preferable to add other computers to your network after you have Configured ICS To add a computer to a wired network on which ICS is Configured, you connect it to the network and turn it on In Network And Sharing Center, you click Internet Options and, on the Connections tab, you click LAN Settings and clear the Automatically Detect Settings check box Provided that the computer's network adapter is set to receive its configuration automatically, and the computer's name is not the same as that of another computer already on the network, the computer joins the network and receives its configuration through ICS If you have changed the default workgroup name (WORKGROUP) on your network, you also need to change this setting on any computer you add.

Adding a computer through a wired connection to a hybrid network is even more straightforward than adding it to a fully wired network You simply plug it in and turn it on By default, it should be Configured to obtain its IP settings automatically In this case, however, it obtains them from the WAP..

type is set to Manual, or you want to start the service without restarting the computer, you use the Services snap-in: 1. While logged on as an administrator or another user account with privileges to manage services, click Start, right-click My Computer, and then click Manage. 2. Expand Services And Applications, and then click Services. 3. In the right pane, right-click your service and then click Start, as shown in Figure 8-6.
