Summary:A method for managing memory allocation in a database receives an invocation of a stored statement defined to allocate objects, each with a stored size. The method determines an actual size relating to the invocation and determines a preferred statement among defined statements with defined object sizes. The defined statements include the stored statement and alternative stored statements that provide an alternative implementation of the stored statement defined to allocate the objects with alternative sizes lower than stored sizes. The preferred statement has defined sizes compliant to actual sizes according to preference criterion based on comparing defined and actual sizes. The method invokes the preferred statement for execution in place of the stored statement when different. The method stores a new statement, having new sizes compliant to actual sizes according to alternate criterion, responsive to unfullfilling a condition based on comparing defined sizes of the preferred statement with actual sizes.
