.NET/Java PDF, Tiff, Barcode SDK LibraryTypes representing ASCII, Unicode, UTF-8, and other character encodings. Also abstract types for converting blocks of characters to and from blocks of bytes. See s 3 and the section Using Regular Expressions and Formatting later in this chapter. Types for creating and synchronizing threads. See 13. Types that enable web applications. See 14. Types for creating windowed applications. See 11. Types that implement standards-based support for processing XML. See s 9 and 15. Types that wrap Win32 API common dialog boxes and components.

If the SGA is much larger due to the UGA being located in it, where does the memory savings come from It comes from having that many fewer PGAs allocated. Each dedicated/shared server has a PGA. This is process information. It is sort areas, hash areas, and other process-related structures. It is this memory need that you are removing from the system by using shared server. If you go from using 5,000 dedicated servers to 100 shared servers, it is the cumulative sizes of the 4,900 PGAs (excluding their UGAs) you no longer need that you are saving with shared server. So, what about DRCP, the new 11g feature It has many of the benefits of shared server such as reduced processes (we are pooling), possible memory savings without the drawbacks. There is no chance of artificial deadlock; for example, the session that holds the lock on the resource in the example above would have its own dedicated server dedicated to it from the pool, and that session would be able to release the lock eventually. It doesn t have the multi-threading capability of shared server; when a client process gets a dedicated server from the pool, it owns that process until that client process releases it. Therefore, it is best suited for client applications that frequently connect, do some relatively short process, and disconnect over and over and over again; in short, for client processes that have an API that do not have an efficient connection pool of their own. Table 10-3 shows the primary namespaces in F# library DLLs from Table 10-1. The following are opened by default in F# code: Microsoft.FSharp.Core Microsoft.FSharp.Collections Microsoft.FSharp.Control Microsoft.FSharp.Text Table 10-3. Namespaces in the DLLs from Table 10-1 Unless your system is overloaded, or you need to use a shared server for a specific feature, a dedicated server will probably serve you best. A dedicated server is simple to set up (in fact, there is no setup!) and makes tuning easier. Note With shared server connections, a session s trace information (SQL_TRACE=TRUE output) may be spread Provides primitive constructs related to the F# language such as tuples. See 3. Provides functional programming collections such as sets and maps implemented using binary trees. See 3 and the section Using Further F# and .NET Data Structures later in this chapter. Provides functional programming control structures including asynchronous and lazy programming. 8 covers programming with the IEvent<'a> type and the IEvent module, and 13 covers the Async<'a> type. Provides types for structured and printf-style textual formatting of data. See 4 for an introduction to printf formatting. Provides extensions to the System.Reflection functionality that deal particularly with F# record and discriminated union values. See 9 for a brief introduction, and see the section Further Libraries for Reflective Techniques section later in this chapter for more details. Provides access to F# expressions as abstract syntax trees. See 9. across many individual trace files; thus, reconstructing what that session has done is more difficult. With the advent of the DBMS_MONITOR package in Oracle Database 10g and above, much of the difficulty has been removed, but it still complicates matters.
