Use the following syntax with ListChildren(): rs.ListChildren(Item, Recursive). The Item argument is the full path of the parent folder whose contents you want to list. For example, use / to list the contents of the root folder (known as the Home folder in Report Manager) or, for nested folders, use a string like /Example Reports/Execution Log Reports. The Recursive argument is a Boolean expression used to specify how much content is retrieved by the method. If True, all items in the specified folder and its nested folders are returned. If False, only the items in the specified folder are returned. The ListChildren() method returns an empty CatalogItem object if the specified folder is empty, but returns an array of CatalogItem objects if items exist there. You can then use a FOR loop to iterate through the CatalogItem objects and read the properties for each object. Because security settings for items as defined in Reporting Services are enforced even when accessing contents programmatically, the array of CatalogItem objects might not contain all items that exist in the specified folder. The credentials that you use to run the script are compared with role definitions and assignments to determine what items you can access with Web service methods. In this procedure, you ll run a script that uses the ListChildren() method to display a list of items and selected properties in the command window. List items in a specified folder 1.

Database transactions and locking Long-running conversations The NHibernate first- and second-level caches The caching system in practice with CaveatEmptor

Now that you understand the basics of object/relational mapping with NHibernate, let s take a closer look at one of the core issues in database application design: transaction management. In this chapter, we examine how you use NHibernate to manage transactions, how concurrency is handled, and how caching is related to both aspects. Let s look at our example application. Some application functionality requires that several different things be done together. For example, when an auction finishes, the CaveatEmptor application has to perform four tasks:

1 2 3 4

17:

Mark the winning (highest amount) bid. Charge the seller the cost of the auction. Charge the successful bidder the price of the winning bid. Notify the seller and the successful bidder.

What happens if you can t bill the auction costs because of a failure in the external credit card system Your business requirements may state that either all listed actions must succeed or none must succeed If so, you call these steps collectively a transaction or a unit of work If only one step fails, the whole unit of work must fail We say that the transaction is atomic: several operations are grouped together as a single indivisible unit Furthermore, transactions allow multiple users to work concurrently with the same data without compromising the integrity and correctness of the data; a particular transaction shouldn t be visible to and shouldn t influence other concurrently running transactions Several different strategies are used to implement this behavior, which is called isolation We ll explore them in this chapter Transactions are also said to exhibit consistency and durability.

Consistency means that any transaction works with a consistent set of data and leaves the data in a consistent state when the transaction completes Durability guarantees that once a transaction completes, all changes made during that transaction become persistent and aren t lost even if the system subsequently fails Atomicity, consistency, isolation, and durability are together known as the ACID criteria We begin this chapter with a discussion of system-level database transactions, where the database guarantees ACID behavior We look at the ADONET and Enterprise Services transactions APIs and see how NHibernate, working as a client of these APIs, is used to control database transactions In an online application, database transactions must have extremely short lifespans A database transaction should span a single batch of database operations, interleaved with business logic It should certainly not span interaction with the user.

Note In this chapter, steps and illustrations are provided for creating applications using Visual Basic .NET. Corresponding C# .NET code samples are available in the C:\Documents and Settings\<username>\My Documents\Microsoft Press\rs2005sbs\chap17 folder, and completed C# .NET projects are in the C:\Documents and Settings\<username>\My Documents \Microsoft Press\rs2005sbs\Answers\chap17 folder. To use these alternate code samples when following the procedures in this chapter, replace VB with CS wherever you need to type a name or open a file.

We ll augment your understanding of transactions with the notion of a long-running user transaction called a conversation, where database operations occur in several batches, alternating with user interaction There are several ways to implement conversations in NHibernate applications, all of which are discussed in this chapter Finally, the subject of caching is much more closely related to transactions than it may appear at first sight For example, caching lets you keep data close to where it s needed, but at the risk of getting stale over time Therefore, caching strategies need to be balanced to also allow for consistent and durable transactions In the second half of this chapter, armed with an understanding of transactions, we explore NHibernate s sophisticated cache architecture You ll learn which data is a good candidate for caching and how to handle concurrency of the cache.
