通过使用线程和连接，下载是串行，正如我上面所说的。
By using threads and join, downloading is serial, as I said above.
每个连接线程还执行身份验证和查询执行。
Each connection thread also performs authentication and query execution.
本文还讨论了如何在应用服务器上配置内存、线程池和JDBC连接池的初始值。
The article also discusses how to initially configure the memory, thread pool, and JDBC connection pool on the application server.
此示例显示了维护线程如何使用获得时间和未使用超时属性防止连接过时。
This example has shown how the maintenance thread USES the Reap time and Unused timeout properties to prevent stale connections.
该引擎提供了事务和崩溃恢复，支持多个连接，而且支持使用一个连接的多个线程。
The engine provides transactions and crash recovery, and allows multiple connections and multiple threads to use a connection.
通常而言，许多应用程序都可以通过调优以下三个核心区域实现一定程度的性能改进：J VM、线程池和连接池。
In general, a large number of applications will realize some improvement from tuning in three core areas: the JVM, thread pools, and connection pools.
图1显示了连接池、会话池、线程池和最大会话属性之间的关系。
Figure 1 shows the relationship between the connection pool, session pool, thread pool and the maximum sessions property.
不能存在并发用户(应用程序独占地访问数据库文件)，但因此也没有额外的线程和TCP连接开销。
There can be no concurrent users (the application has exclusive access to the database files), but there are no additional threads nor TCP connection overhead.
这是一种异步服务Web请求的可扩展方式，无需在服务器上输入所有连接和线程资源。
This is a scalable way of servicing Web requests asynchronously without tying up all of the connection and thread resources on a server.
因为上面介绍的模式非常有效，所以可以通过连接附加线程池和队列来进行扩展，这是相当简单的。
Because the pattern demonstrated above is so effective, it is relatively simple to extend it by chaining additional thread pools with queues.
有关更多信息，请参见下面的使用全局连接工厂和线程级别连接缓存。
For more information, see Use of a global connection factory and thread level connection caching below.
尽管这个基本模式比较简单，但可以通过将队列和线程池连接在一起，以便将这个模式用于解决各种各样的问题。
While this basic pattern is relatively simple, it can be used to solve a wide number of problems by chaining queues and thread pools together.
作为此支持的一部分，WebSphereMessageBroker使用资源管理器管理连接、线程关联性、连接池和连接的生命周期。
As part of this support WebSphere Message Broker manages the connections, thread affinity, connection pooling, and life cycle of connections with resource managers.
使用全局连接工厂和线程级别连接缓存。

在WebSphereApplicationServerV6.x 之前，在并发客户端连接数和Web容器线程池中的线程数之间存在一对一的映射。
Prior to WebSphere Application Server V6.x, a one-to-one mapping existed between the number of concurrent client connections and the threads in the Web container thread pool.
这也将有另一个问题-背景和任何操作，在使用的上下文中的上下文或数据库连接实体不是线程安全的。
This will also have another problem - context and any manipulation with entities in the context or a database connection used by the context is not thread safe.
在我的主线程是维护脚本，和“其他线程”是一个连接处理。
"Main" thread in my case is the maintenance script, and "other thread" is a connection handler.
一般蛮力的SSH不是问题，只要你的服务器没有一吨的线程接受连接和密码足够复杂。
Generally brute forcing of SSH is not a problem so long as your server doesn't have a ton of threads accepting connections and your passwords is sufficiently complex.
从配置参数调整、设置监听线程和运行日志等管理方案的实施，弥补了现有连接池技术的不足。
It applies configuration parameter, setting up the thread of monitoring and running log of management scheme etc, to solve the inefficiency of current connection pool.
也可以指示错误信息接口支持、连接点和自由线程封送处理。
You can also indicate support for the error information interface, connection points, and free-threaded marshaling.
