SET LOCKBLOCK

Specifies the maximum number of blocks that Essbase can get addressability to concurrently when calculating a sparse member formula.

You can choose one of three levels. The number of blocks that Essbase can get addressability to at each level is defined using the CALCLOCKBLOCK setting in the essbase.cfg file.

Syntax

SET LOCKBLOCK HIGH | DEFAULT | LOW;
Parameter Description

HIGH, DEFAULT, and LOW

Levels defining the number of blocks that Essbase can get addressability to concurrently.

Notes

When a block is calculated, Essbase locks (gets addressability to) the block along with the blocks containing its children. Essbase calculates the block and then releases it along with the blocks containing its children.

By default, Essbase allows up to 100 blocks to be locked (addressable) concurrently when calculating a block. This is sufficient for most database calculations.

However, you may want to set a number higher than 100 if you are consolidating very large numbers of children in a formula calculation. This setting ensures that Essbase can get addressability to all the required blocks when calculating a data block and that performance will not be impaired.

For more information on data blocks, see the Oracle Essbase Database Administrator's Guide.

Example

If the essbase.cfg file contains the following settings:

CALCLOCKBLOCKHIGH           500
CALCLOCKBLOCKDEFAULT        200
CALCLOCKBLOCKLOW            50

then:

SET LOCKBLOCK HIGH;

means that Essbase can get addressability to up to 500 data blocks when calculating one block.

SET LOCKBLOCK DEFAULT;

means that Essbase can get addressability to up to 200 data blocks when calculating one block.

SET LOCKBLOCK LOW;

means that Essbase can get addressability to up to 50 data blocks when calculating one block.
