Abstract This article introduces the working principle of the JDBC-based database connection pool, describes the transaction processing and multi-database servers of the connection pool technology.
Various key technologies propose an efficient connection pool management policy. At last, the specific implementation process of the database connection

1. For the ASP. NET database connection pool, you can use a group of name-value pairs to configure the connection pool as a link string. For example, you can configure whether the pool is valid (which is valid by default). The maximum and minimum capacity of the pool is used for the time when the queued requests that o

Simply put, if an application needs to create and destroy threads frequently, and the task executes in a very sho
1. Why does it take a lot of time to create and initialize new objects using the object pool technology. In the initialization of such objects, if you rely on rpc Remote calls to create objects, such as connecting to remote service resources through socket or http, the most typical is the database service and RemoteQueue ), establish a connection

Introduction
C/C ++ memory management is a headache for almost every programmer. allocate enough memory, track the memory allocation, and release the memory when it is not needed-this task is quite complicated. The direct use of the system to call malloc/free and new/delete for memory allocation and release has the following drawbacks:
When calling malloc/new, the system needs to find an idle memory in the memory idle block table
Most ADO. NET data providers use connection pools to Improve the Performance of applications built around Microsoft's disconnected. net structure. The application first opens a connection (or obtains a connection handle from the connection pool), then runs one or more queries, processes the row set, and finally releases the connection back to the connection pool. Without a connection
Currently, the connection pool of JDBC2 is only an interface and is not actually implemented. JDBC3 is under development,
It is reported that the connection pool is supported, ..........
JDBC3 uses the JNDI technology, and the configuration of the connection pool can upset a master.
Currently, the connection pool impl
The Boost library is a portable open-source C ++ function library. Given that STL (Standard Template Library) has become an integral part of the C ++ language, it is no exaggeration to say that, boost is currently the most influential universal C ++ library. The Boost library is initiated by members of the C ++ Standards Committee Working Group. Some of the content is expected to become the content of the next-generation C ++ standard library and is a quasi-standard library.The Boost memory

Introduction?? This article will introduce the Chang and packing unpacking mechanism, the reason is that the two together introduced, is because many articles on the internet when it comes to Chang, the wrapper class cache mechanism, Java constant pool, mixed together in a discussion, or even completely the two as a whole, for beginners to bring a lot of trouble, I just came over. Also, because the caching of wrapper classes is the same as the idea of
1, for a asp.net database connection pool, you can configure a link pool as a link string using a set of name-value pairs. For example, you can configure whether the pool is valid (default is valid), the maximum and minimum capacity of the pool, and the time that the queued request for the link is blocked. The followin
