C O m
Introduction
C O m is a powerful new version of the technical function of M i C R O S O f T old-style component object mode. Starting from Windows 2000, C O m adds many previously independent technologies, such as MICrosoft Transaction Server, M T, Ms, Ms, Microsoft Messaging Queue, M s M q, directly adds to the operating system. Although COM provides a very friendly user interface (named component service manager, which is Component Services Explorer), but it still rely on a set of registry entries, system administrators can fully use some of them. Server COM device (COM Installation). Very interesting, different from the standard C O m, C O m does not save its data in a standard registry, but save the data in a dedicated database called R E G D B. COM provides a wide range of services for Windows 2000 developers, including Distributed Tringsactions, DCOM Support, Asynchronous Procedure Calls, Memory Database (In-Memory Database), Object Pool (Object Pooling) and Load Balancing (L OA DB Alancing).
COM capacity
Com provides a strong service for Windows 2000 systems, including: transaction. Load balancing and fault recovery support. Object pool and Just (Just In Ti ME, scheduled) object activation. Asynchronous function calls. Publishing Subscribe event
DCOM support
C O m provides comprehensive support to remote component interaction using distributed C O m (D C O m). If necessary, a special registry entry can be used to manually control it. In addition, the new protocol of D C O m is called C i s (component I n t e R N e t service, and Component Internet Services) allows C O M components to connect through standard I n t e R N e t. D C O m itself should be managed by D C O m C F G instead of Component Services.
The ODBC resource pool is a software object that consumes memory and time is the O D b C database connection, and a busy server in the specified time may have many connection creation and close. C O m is fully improved by saving O D B C connection resource (or even when they are not in use), and correctly enhance performance.
IMDB
IMDB (In-Memory Database) is one of the most useful features of C O m . I M D B allows data from the server to be placed in memory and treated as the local O D B C data source, which has the ability to be opened, running S Q L query statements. Registry entries can control the three main characteristics of I M D B: Connection (C O N N E C T I O N), allocated memory (A l L o C A T E DM E M O R Y) and B L O B. 1. Connecting I M D b is like a standard, working with the O D B C compatible database server, so it also limits the number of concurrent connections. After reaching the maximum number of connections, any additional requests will fail until there are available connections. The system administrator can improve the upper limit of concurrent connections by manually modifying the registry settings. 2. All I m D b databases allocated all I m D b use a certain number of hard-wired memory, which limits the amount of data that can be included in a database. System administrators can increase and reduce this restriction through registry to achieve optimal performance. 3. Blobblob (Binary Large Objects, Binary Object) is a special database domain for saving binary data (such as images). I M D B has a relatively small default size limit on B L O b. If a database environment is required, the system administrator can add dimensional limit by setting the registry value. Allow COM Registry Database Auto Backup
