Documentation
Definition
Determines how numbers are determined in parallel processing:
- Determination from a number range (1)
- Fixed assignment to a number (2)
Use
Determination from a number range (1):
If you choose this setting, the system defines a number range when a table is generated. The system then distributes the number range to the available work processes of the affected work process category This means that an application server with many work processes of the affected work process category has more number ranges available than an application server with fewer work processes. The system randomly determines a number from this range for the term. The work processes and therefore the number range intervals for the term are utilized differently. To prevent this from happening, program logic that shifts the random values cyclically in one hour intervals has been incorporated.
his setting is useful for dialog processes as fewer lock times occur in a dialog process than in a batch operation.
Note:
During processing, the system randomly determines a value in this option from the start value (STRAT_NUM) and the offset value (NUM). This value is within the defined number range (START_NUM to MAXNUM).
Fixed assignment to a number (2):
To determine a simple number, choose the fixed setting (2).
This setting is useful for batch processes as the processes in a work process run in sequence and the average utilization of the intervals is more even.
Note:
In this option, the value is made up of the start value (START_NUM) and the offset (NUM).
The assignment is made so that the number ranges are sorted by database servers and application server and there is no overlapping.
