SQL Server Connection Pooling (ADO.NET)Connecting to a database server typically consists of several time-consuming steps. A physical channel such as
Connection pooling can help reduce the overhead of retrieving this information. Features in SQL Server Management Studio generally use the same base connection entered by the user in the connection dialog, and different features can reuse the same physical connection instead of opening a new one....
Pooling connection连接可以极大促进应用程序的性能与可扩展性。SQL Server .NET Data Provider自动提供connection pooling。用户也可以自己提供一些连接字符串修饰符来控制connection pooling。 Pool的创建与指定 当连接打开时,基于精确匹配算法的一个connection pool被创建,这个算法将pool和这个连接的连接字符串相关联。在新...
After a SQL Server application role has been activated by calling thesp_setapprolesystem stored procedure, the security context of that connection cannot be reset. However, if pooling is enabled, the connection is returned to the pool, and an error occurs when the pooled connection is reused....
SQL Server .NET Data Provider自动提供connection pooling。用户也可以自己提供一些连接字符串修饰符来控制connection pooling。 1、Pool的创建与指定 当连接打开时,基于精确匹配算法的一个connection pool被创建,这个算法将pool和这个连接的连接字符串相关联。在新连接打开时,如果连接字符串不精确匹配一个已存在的pool,新...
Connection Pooling会减少打开新建连接的次数. Pooler拥有物理连接的所有权. 对每一种数据库连接配置它都让几个处于活动状态的连接持续地处于活动状态, Pooler通过这种方式来管理数据库连接. 每当一个用户对一个connection调用Open方法, Pooler都会在连接池中寻找一个可用的active的连接. 如果有这样的一个connection可用,...
连接池(Connection Pooling)SQL Server.NET PoolConnection数据库连接是一种关键的有限的昂贵的资源,它的好坏影响到整个应用程序的性能指标.数据库连接池正是针对这个问题提出来的.数据库连接池负责分配,管理和释放数据库连接,它允许应用程序重复使用,这项技术能明显提高对数据库操作的性能.在本文中,重点介绍一下在SQL...
The Microsoft JDBC Driver for SQL Server provides support for Java Platform, Enterprise Edition (Java EE) connection pooling. The JDBC driver implements the JDBC 3.0 required interfaces to enable the driver to participate in any connection-pooling implementation that is provided by middleware vendors ...
Learn the details of connection pooling when using the Microsoft Drivers for PHP for SQL Server and how the experience may differ depending on your operating system.
Pooling(池):确定是否使用连接池。如果值为真的话,连接就要从适当的连接池中获得,或者,如果需要的话,连接将被创建,然后被加入合适的连接池中。其缺省值为真。 User ID(用户ID):用来登陆数据库的帐户名。 Workstation ID(工作站ID):连接到SQL Server的工作站的名称。其缺省值为本地计算机的名称。
