SQL Server system memory management in the absence of configured memory maximums, many times we find that the system memory running SQL Server is often high. This is because his strategy for memory usage is how much idle memory to occupy, until memory usage takes into account the system peak (reserved memory based on the system default reserved use, at least 4M), will clear some

On the network, there are some cache servers, and the browser itself has caching capabilities.For example:The 1th time you visit this page, the normal download picture, the return value is 200:Packet capture analysis of the response head:Based on a premise-the image will not be changed frequently, the server returns 200 at the same time, also return the image's eigenvalues (signature ETag), when the browser

SQL Server servers run for a while to find that memory is growing exponentially to 98%. Workaround: Restart the host computer to restart the SQL Server service setting maximum memory the first two methods are less suitable for the online environment and the indicator does not recommend setting the maximum memory if there are SQL Server servers constantly eating m

1) Image Service Cache Just like creating a cache for the map service, you can now create a server cache for the image service. The two use the same tool to create a cache. 2) create cache for custom regions of interest W

The BIEE itself provides several ways to manage the cache, either by setting the cache's expiration time at the physical level or by invoking the Sapurgeallcache () process.The first two methods are passive management policies (the event table is timed polling, the expiration time is specified as valid duration), is inefficient, and the individual is more active in the cache management policy. This is to pr

To improve browsing performance, ArcGIS Server is usually used for map caching (commonly referred to as "tile technology "). For example, mapabc and GoogleMap currently use this technology.The so-called map cache technology refers to cutting a map into images of certain specifications and saving it to a computer hard disk according to certain mathematical rules. When a user accesses the map service through

Article Title: reverse proxy-based Web Cache accelerates modern server management. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 Implementation of reverse proxy cache Acceleration Based on Apache mod_proxy Apache contains

By using ArcGIS Server for map Publishing, the current more popular map caching techniques (popular as "tile technology") are usually used to enhance browsing performance. such as the current MAPABC and GoogleMap is precisely the use of this technology. The so-called map caching technology, is according to a certain mathematical rules, the map into a certain size of the picture saved to the computer hard disk, when the user through the client browser
