NCache 4.4 - Online Documentation

Cache Size

 
Through this configuration option, you can specify an upper limit on the size of the cache in MB. The number of items in the cache are limited by maximum size of the cache and amount of free system memory (virtual or physical). If some eviction policy is specified, whenever total data size in cache reaches maximum size or when less than 10% of memory is left in the system, items are removed from the cache as per eviction policy. Maximum size of a cache can be specified by one of following two ways.
 
Using NCache manager
 
Default cache size is 250 MB but it can be changed as follows.
 
  • Click on the cache name in Cache Explorer to open cache settings
  • Go to the Main tab.
  • Change the Cache Max. Size as per your needs.
 
 
  • Right click the cache in Cache Explorer and select Apply Configuration option.
 
 
Using Command Line Tool
 
The size of the cache is also specified at the time of creating cache using S option in the definition using command line tool as follows.
 
  • Open command prompt
  • Go to the NCache tools directory: cd %NCHOME%/bin/tools
  • Use createcache.exe, provide the required information: 
createcache.exe Cache /s test1 /S 250
  • Hit ENTER key, it will create Cache of local topology of size 250mb on test1 node. Here, instead of 250, any size can be mentioned.
 
Through Config.ncconf
 
You can specify the cache max size through Config.ncconf as follows.
 
<cache-config name="mypartitionedcache" inproc="False" config-id="1" last-modified="6/20/2010 3:50:34 PM">
  <storage type="heap" cache-size="250mb"/>
</cache-config>
