Parameter
zcsa/tablp_request_unit
Short text
Counter for eviction and reorganization of the table
Parameter Description
This parameter triggers the frequency of an eviction and reorganization run of the single record buffer. Following each “zcsa/request_unit” read access to the buffer, the system checks whether an eviction or reorganization run is to take place. If this value is increased, there is a risk that the eviction is performed too infrequently and this would mean that buffered tables cannot be stored in the buffer. The result can be a loss in performance because accesses to these tables then go to the database. On the other hand, the value of this parameter must not be set too low because this could result in the notification mechanism becoming overloaded and the queue overflowing.
