the database cache manager
Tradução de "the database cache manager" em chinês
数据库缓存管理器
Database Cache Size is the amount of system memory used by the database cache manager to hold commonly used information from the database file(s) to prevent file the database cache size seems to be too small for optimal performance and there is very little available memory on the system (see Memory/Available Bytes), adding more memory to the system may increase performance. If there is a lot of available memory on the system and the database cache size is not growing beyond a certain point, the database cache size may be capped at an artificially low limit. Increasing this limit may increase performance.
Database Cache Size 是資料庫快取管理員用來保留資料庫檔案中經常使用的資訊，以防止進行檔案作業的系統記憶體數。如果資料庫快取大小對於取得最佳效能來說顯得太小，且系統上的可用記憶體過少 （請參閱記憶體/可用的位元組），則可將更多的記憶體新增到系統以增加效能。如果系統上有許多可用記憶體，而資料庫快取大小卻無法超過某個限制值，則資料庫快取大小可能是處於手動的低限制值。增加此限制值可增加效能。

Database Cache Size 是数据库缓存管理器用来保存来自数据库文件的常用信息，以阻止文件操作的系统内存量。如果数据库缓存看起来过小而无法优化性能，而且系统上的可用内存太少（参见"内存/可用字节"），则给系统增加更多内存可能会提高性能。如果系统中有大量可用内存，但数据库缓存大小的增加没有越过某点，则数据库缓存大小可能被人为限制在了较低的范围。增加此限制值可能会提高性能。
Database Page Evictions/sec is the rate that database file page requests that require the database cache manager to allocate a new page from the database cache force another database page out of the cache. The eviction count is charged when the page is allocated and not when the previous owner of that page was actually evicted from the cache. If this rate is too high, the database cache size may be too small.
Database Page Evictions/sec 是要求数据库缓存管理器从数据库缓存中分配新页面的数据库文件页面请求强制另一个数据库页面退出缓存的速率。此页面被分配时，逐出数增加，而当该页面的前一个所有者从缓存中逐出时，逐出数并不会发生变化。如果此速率过高，则说明数据库缓存可能太小。
Database Cache Size Effective is the amount of memory reserved for fully dehydrated page data by the database cache manager. This is not the actual system memory used, but the hypothetical memory usage in effect if all dehydrated/compressed database cache buffers were rehydrated/uncompressed.
Database Cache Size Effective 是資料庫快取管理員為完全凍結的頁面資料保留的記憶體數目。如果所有已凍結/壓縮的資料庫快取緩衝區是解除凍結/解壓縮的，則這不是實際使用的系統記憶體，而是有效的假設記憶體使用量。
Database Cache Size Min is the minimum amount of system memory configured for use by the database cache manager to hold commonly used information from the database file(s) to prevent file operations. [Dev Only]
Database Cache Size Min 是为了让数据库缓存管理器用于保存数据库文件中的通用信息以避免文件操作而配置的最低数量的系统内存。［仅适用于开发人员］
Database Page Faults/sec is the rate that database file page requests require the database cache manager to allocate a new page from the database cache.
Database Page Faults/sec 是数据库文件页请求要求数据库缓存管理器从数据库缓存中分配新页的速率。
Database Page Faults/sec is the rate that database file page requests require the database cache manager to allocate a new page from the database cache.
Database Page Faults/sec 為資料庫檔案頁要求需要資料庫快取管理程式從資料庫快取配置新頁的比率。
