Specifies the maximum number of blocks that Analytic Services can get addressability to concurrently when calculating a sparse member formula.
SET LOCKBLOCK HIGH | DEFAULT | LOW;
HIGH, DEFAULT, and LOW | Levels defining the number of blocks that Analytic Services can get addressability to concurrently. |
SET LOCKBLOCK specifies the maximum number of blocks that Analytic Services can get addressability to concurrently when calculating a block.
You can choose one of three levels. The number of blocks that Analytic Services can get addressability to at each level is defined using the CALCLOCKBLOCK setting in the essbase.cfg
file.
When a block is calculated, Analytic Services locks (gets addressability to) the block along with the blocks containing its children. Analytic Services calculates the block and then releases it along with the blocks containing its children.
By default, Analytic Services 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 Analytic Services 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 Database Administrator's Guide.
If the essbase.cfg
file contains the following settings:
CALCLOCKBLOCKHIGH 500 CALCLOCKBLOCKDEFAULT 200 CALCLOCKBLOCKLOW 50
then:
SET LOCKBLOCK HIGH;
means that Analytic Services can get addressability to up to 500 data blocks when calculating one block.
SET LOCKBLOCK DEFAULT;
means that Analytic Services can get addressability to up to 200 data blocks when calculating one block.
SET LOCKBLOCK LOW;
means that Analytic Services can get addressability to up to 50 data blocks when calculating one block.
