Each scheduler has a list of pending i os that are checked to determine whether they have been completed every time there is a context switch 每个计划程序都有一个挂起i / o的列表,通过检查该列表,可以确定每次有上下文切换时它们是否已经完成。
" context switching " in sql server books online describes how to change the execution context to explicitly impersonate another user in a sql server 2005 database 要能够使用字符串串联,需要授予对表的select权限,这样,所有数据都将暴露给攻击者。
Option to provide a means of reducing the system overhead associated with the excessive context switching sometimes seen in symmetric multiprocessing environments 选项可以减少有时在对称多处理( smp )环境下遇到的、与过多的上下文切换有关的系统开销。
No context switches will occur , because the running thread is continually picking up completion packets and the other threads are unable to run 这样就不存在着环境的切换,因为该处于运行中的线程就会连续不断地从队列中取走完成包,而其他的线程就不能运行了。
When context switches are made on a thread , the next user - supplied code module stepped into may not relate to the code that was in the process of being debugged 如果线程的上下文发生了转换,进入并单步执行的下一个由用户提供的代码模块可能与正在调试的代码无关。
Fixed processes are suitable only for system server processes such as the file server , window server etc . since the majority of context switches involve these processes 固化进程只适用于系统服务进程,例如文件服务,窗口服务等。因为绝大多数的上下文切换都包括了三个步骤。
When excessive context switching is present , lightweight pooling can provide better throughput by performing the context switching inline , thus helping to reduce user kernel ring transitions 如果出现过多的上下文切换,轻型池可以通过上下文切换内联化,从而降低用户/内核环的转换频率,达到提高吞吐量的目的。
Too many threads in a process tend to slow down the server because of extra context switches , causing the operating system to spend cpu cycles on maintaining threads rather than processing requests 因为额外的上下文交换导致操作系统将cpu周期花在维护线程而不是处理请求上,所以进程中有太多线程往往会降低服务器的速度。
The sql server database engine security functionality includes highly granular authentication , authorization , and validation mechanisms ; strong encryption ; security context switching and impersonation ; and integrated key management Sql server数据库引擎安全功能包括高粒度身份验证、授权和验证机制;增强加密;安全上下文切换和模拟以及集成的密钥管理。
A context switch is the computing process of storing and restoring the state (context) of a Process so that execution can be resumed from the same point at a later time. This enables multiple processes to share a single CPU.
