It is important to track active transactions, especially when working with nested transactions and savepoints. When working with stored procedures, error handling routines should verify transaction completion (COMMIT or ROLLBACK) before closing a connection. You can use the @@trancount global variable to see the number of open transactions in the current session. For a greater level of detail, you can use the following transaction-specific dynamic management objects:

If an administrator removes the password on a user account, the user account will lose all EFS-encrypted files, personal certificates, and stored passwords for Web sites or network resources. Each user should make a password reset disk to avoid this situation. To create a password floppy disk, open User Accounts and, under Related Tasks, click Prevent A Forgotten Password. The Forgotten Password Wizard steps you through creating the password reset disk.

The Add Printer Wizard guides you through the steps to add a printer that is connected to the print server. The number of local printers that you can connect to a print server through physical ports depends on your hardware configuration. Table 11-2 describes the Add Printer Wizard pages and options for adding a local printer.

' VB Protected Overrides Sub OnStop() If serviceHost IsNot Nothing Then serviceHost.Close() serviceHost = Nothing End If End Sub // C# protected override void OnStop() { if (serviceHost != null) { serviceHost.Close(); serviceHost = null; } }

To further practice and reinforce the skills you learned in this chapter, you can perform the following tasks:

Physical memory pressure is pretty straightforward; if your server is under load and running low on available memory, Windows will issue a LowMemoryResourceNotification, which SQL Server will recognize and handle. Virtual address space memory pressure is more difficult and generally more limiting to SQL CLR because it might cause memory pressure even when there is enough physical memory available. This might happen because, as was noted above, most SQL CLR memory allocations occur outside of the SQL Buffer Pool in what is called the MemToLeave area. The size of this area of memory is set by the -g flag on SQL Server startup, but by default, it is at least 256 MB. Another item that database developers want to closely manage is how much time CLR objects spend executing. You can determine this by executing the following query:

After this lesson, you will be able to:

Oksana is responsible for the administration of several departmental file servers at the local community college. Each file server is configured with three hard disk drives. The first hard disk drive contains a single volume hosting the operating system and program files. The other two hard drives host a single spanned volume. All the shared folders are located on the spanned volume. Backups are performed every 24 hours to DAT. A full backup of all files and folders on the spanned volume, including a backup of the System State data, occurs every Sunday at 5 A.M. Incremental backups occur on Monday, Wednesday, and Friday at 6 A.M. Each tape is labeled with the day the backup it stores is taken. One of the disks hosting the spanned volume fails early Fri day afternoon. Oksana replaces the disk and recreates the spanned volume. Which of the following correctly describes the order in which Oksana should restore the backup tapes to the spanned volume
