| -----------------------                                              |
| This parameter triggers the frequency of a displacement and          |
| reorganisation run for the table buffer. After each                  |
| 'zcsa/request_unit' read access to the buffer the system checks whether|
| a displacement or reorganization run is to take place.
| If this value is raised, there is the danger that the displacement   |
| is carried out too seldom and as a result, buffered tables           |
| cannot be stored in the buffer. This can result in a
| loss of performance, since the access to these tables                |
| go to the database. Conversely, the parameter must not have too low  |
| a value, since this results in am overloading of the                 |
| authorization mechanism (ADM message) and may lead to an overflow    |
| of the corresponding queue.                                          |
