Work Areas

Three processes create temporary work areas on the disk:

To create these temporary work areas, Essbase may require disk space equal to the size of the entire database. Restructuring and migration need additional work space the size of the outline. Because none of these activities occur simultaneously, a single allocation can represent all three requirements.

To calculate the size of a work area used for restructuring, migration, and recovery, calculate the sum of the sizes of the following database components from Table 247, Worksheet: Estimate of Disk Requirements for a Database:

Use the following formula to calculate the size of the work area:

work area = size of compressed data files 
+ size of index files 
+ fragmentation allowance 
+ outline size 

Write the result of this calculation to the cell labeled DI in Table 247, Worksheet: Estimate of Disk Requirements for a Database.
