page memory system的意思|示意

The most important changes were made to address paging issues, where database servers frequently page out computational pages, even though the system has enough free memory.

最重要的更改是处理分页问题，即使系统拥有足够的空闲内存，数据库服务器频繁地交换出计算性页面也可能导致这个问题。

However, if you make it too large, you can waste valuable memory resources on your managed system due to the size of the page table created for the partition.

然而，如果将它设置的太大，则可能会由于为该分区创建的页表大小而浪费所管理系统上的宝贵内存资源。

The page section in the output indicates current paging status of your system; pi column indicates number of pages read into the memory and po column indicates number of pages paged out of the memory.

输出的 page 部分指示系统的当前分页状态；pi 列指示读入内存的页数目，而 po 列则指示移出内存的页数目。

With a simple vmo change here, you can actually tune the system to provide for large page usage, which can improve system performance substantially in very memory-intensive applications.

通过下面一项简单的vmo更改，您就可以对系统进行优化以提供大型的页面，从而对于消耗大量内存的应用程序极大地提高系统性能。

These virtual addresses are mapped to physical memory by page tables, which are maintained by the operating system kernel and consulted by the processor.

这些虚拟地址映射到物理内存页表，这是维护操作系统的内核和处理器咨询。

If a process requests a page in memory and the system cannot find the page at the requested location, a page fault occurs.

如果某个进程请求内存中的某个页面，但是系统在所请求的位置中未找到该页面，则会发生页面错误。
