MicroStrategy ONE

Server-Side Behavior Changes for Cache Settings

Beginning with MicroStrategy Update 2, Intelligence Server will not be enforcing the "Formatted Documents - Maximum Number of Caches" setting if the values are set below the default value of 1000000 (1M).

Beginning with MicroStrategy 2020 Update 1, Intelligence Server will not be enforcing the following 3 cache count limit settings if the values are set below the default value of 100000 (100K):

  • Dataset - Maximum Number of Caches
  • Formatted Documents - Maximum Number of Caches
  • Maximum number of cubes

When configuring the registry setting for the left disk size to 0, Intelligence Server will fall back to use the cache count limit settings as the maximal number for document, report, or cube cache entries. This allows the opportunity to fall back to the old behavior

Make Document Cache Expiration dependent on the lifetime of its datasets (standalone or embedded)

Document Cache Expiration based directly on Cache Duration (hrs) will be retired for newly created document caches.The DssProjectReportCacheLifeTime, will remain in effect for existing document caches that remain unchanged.

Monitor the disk and stop to generate caches for document, report, or cube if the free disk space is less than a specific value

Intelligence Server will use a single absolute value representing the left free disk space as a threshold to stop generating caches, the default value for release build is 10GB.

This setting can be configured through the registry. If the registry number is 0, we will fall back to use the 3 cache count limit settings.

The registry setting for the disk size:

  • Key: SOFTWARE\\MicroStrategy\\Data Sources\\CastorServer
  • Value: Reserved Disk Space(GB)

Update the page cache number limit from 10 to 20 for a certified Dashboard.

If a value larger than 20 is already set for a certified Dashboard, the value will be kept.

At least 20 page caches will be generated for any Shortcuts or Bookmarks for a certified Dashboard.

For example, suppose this setting was customized on a MicroStrategy 10.11 installation and the customized value is set to X.

Intelligence Server will:

  1. Generate at most X pages of caches for the Dashboard Shortcut or Bookmark for an uncertified Dashboard.
  2. Generate at most Max(X, 20) pages of caches for the Dashboard Shortcut or Bookmark for a certified Dashboard.
