A resource dispenser manages nondurable shared state on behalf of the application components within a process. Resource dispensers are similar to resource managers, but without the guarantee of durability. MTS provides two resource dispensers:
The ODBC resource dispenser manages pools of database connections for MTS components that use the standard ODBC interfaces, allocating connections to objects quickly and efficiently. Connections are automatically enlisted on an object's transactions, and the resource dispenser can automatically reclaim and reuse connections. The ODBC 3.0 Driver Manager is the ODBC resource dispenser; the Driver Manager DLL is installed with MTS.
The Shared Property Manager provides synchronized access to application-defined, process-wide properties (variables). For example, you can use it to maintain a Web-page hit counter or to maintain the shared state for a multiuser game.
