How to improve calculation script performance in Essbase?

How to improve calculation script performance in Essbase?

Essbase uses memory to optimize calculation performance, especially for large calculations….Managing Caches to Improve Performance

1. Calculator cache. Ensure that the calculator cache is large enough to optimize calculation performance.
2. Dynamic calculator cache.
3. Index cache.
4. Data cache.
5. Data file cache.
6. Application cache.

How to optimize the performance in Essbase?

You can remove fragmentation and compact an Essbase database using either of the following methods:

1. Perform an export of the database, delete all data in the database with CLEARDATA, and reload the export file.
2. Run the MaxL statement alter database force restructure.

What is Essbase calculation script?

Calculation scripts are text files that define how to calculate data in the database. For example, you can calculate part of a database or copy values between members. Because calculation scripts perform specific mathematical operations on member, they are typically associated with a particular database.

How is number of blocks calculated in Essbase?

Multiply the number of stored members of the first dense dimension (line a) by the number of stored members of the second dense dimension (line b) by the number of stored members of the third dense dimension (line c), and so on, to determine the total number of cells in a block.

What is intelligent calculation in Hyperion Essbase?

Introducing Intelligent Calculation. If you then load a subset of data, on subsequent calculations, Essbase calculates only the data blocks that have not been calculated and the calculated blocks that require recalculation because of the new data. This process is called Intelligent Calculation.

What is label only in Essbase?

Essbase – Consolidation Storage Properties Essbase sums the values of store data members and stores the result at the parent level. For example, you can change a store data member to a label only member. Members with the label only tag, for example, do not have data associated with them.

What is restructuring in Essbase?

Dense restructure: If a member of a dense dimension is moved, deleted, or added, Essbase restructures the blocks in the data files and creates new data files. When Essbase restructures the data blocks, it regenerates the index automatically so that index entries point to the new data blocks.

How do you do dense restructure in Essbase?

To perform a dense restructure, Essbase does the following:

1. Creates temporary files that are copies of the following files: essxxxxx.ind essxxxxx.pag dbname.otl dbname.esm dbname.tct.
2. Reads the blocks from the database files copied in step 1, restructures the blocks in memory, and stores them in the new temporary files.

Who owns Essbase?

Oracle Corporation
Essbase began as a product from Arbor Software, which merged with Hyperion Software in 1998. Oracle Corporation acquired Hyperion Solutions Corporation in 2007, as of 2009 Oracle market Essbase as “Oracle Essbase”, both on-premises and in Oracle’s Cloud Infrastructure (OCI).

How does Essbase calculate database size?

Total number of cells in a block: 50. 8 bytes per cell, so 50 * 8 = 400 bytes expanded block size. You have 2 sparse dimensions: Markets – 10 stored members.

How is block created in Essbase?

Essbase creates a data block for each unique combination of sparse dimension members (providing that at least one data value exists for the combination). Each data block contains all the dense dimension member values for its unique combination of sparse dimension members.
