Documentation

Definition

This ID determines whether the number intervals are buffered for assignements and checks.

Use

The number interval buffer is in the Shared Memory of the application server. Each buffer is used to store the external number intervals and a certain number (subinterval) of the internal number intervals. If the numbers of an internal number interval are used up, numbers are taken from the database via the number range server. The status of the number interval in the database is increased by the number of numbers fetched to the buffer.

Procedure

Examples

Dependencies

When buffering number intervals, gaps may result in number assignment. Buffering is therefore not possible for applications, which require continuous number assignment.
