tableBASE manages memory in a Data Space referred to as a TSR. It manages memory based on total table demand patterns and attempts to provide optimum memory utilization based on the needs of applications currently running.
The TSRSIZE parameter is an integer that represents the amount of storage to be used for the TSR. This parameter controls the size of the Data Space. The maximum value is 2G. This parameter must be selected with care as choosing a TSR that is too small may mean that your application may run out of space in which to load tables. The TSR must be of size large enough to hold all the tables that are open simultaneously. The delivered default value for the TSRSIZE is 10M for all interfaces.
