Default Cache Settings
The following table shows the installed default sizes assigned to cache. You can modify the cache size if you do not want to use the default setting; however, you cannot reduce it below the minimum size shown below.
The following table shows the cache size used for separate storage sessions:
Session | Cache Size |
Configuration |  Default Size: 8 MB Minimum Size: 8 MB |
Run-time data | Default Size: Size of the physical memory on the host machine or the value specified in the max-memory-size parameter, whichever is smaller. That is, MIN ( physicalMemorySize, max-memory-size). Minimum Size: 64 MB |
The following table shows the cache size used for combined storage sessions:
Session | Cache Size |
Configuration | Default Size: Size of the physical memory on the host machine or the value specified in the max-memory-size parameter, whichever is smaller. That is, MIN ( physicalMemorySize, max-memory-size). Minimum Size: 64MB |
Note:
The actual size of the cache may exceed the specified maximum by up to 15% during peak loads. This 15% allowance gives Broker Server the leeway to expand the cache in order to accommodate an entire document.
