Cache-Related Overhead

Essbase uses additional memory while it works with the caches.

The calculation for this cache-related overhead uses the following factors:

  To calculate the cache-related overhead at startup:

  1. Calculate half the index cache size, in bytes.

    index cache size 
    * .5 
    = index cache-related overhead
    
  2. Calculate additional cache overhead in bytes using the following formula:

    ((# of server threads allocated to the Essbase Server process * 3) 
    * 256) 
    + 5242880 bytes 
    = additional cache overhead
    
  3. Sum the index cache overhead plus the additional cache overhead.

    cache-related overhead 
    = index cache-related overhead 
    + additional cache overhead

    Write the result to the cell labeled MC in Table 250, Worksheet: Estimating Memory Requirements for a Database.
