the amount of memory available for the reorganization process volatile and nonvolatile the number and speed of access paths to the data being reorganized and the particular overhead associated with running cooperating tasks or processes within a given environment must be considered tradeoffs between these factors will inform the decision maker as to how many of each task read sort and write should be selected to optimize the reorganization process e g minimize start to finish reorganization time while complex this task is within the ability of those having ordinary skill in the art of database system design management and administration it is noted that the number of read sort and write tasks initiated in accordance with the invention are independent of one another thus in one embodiment the number of read tasks and the number of sort tasks are equal with one sort task associated with each logical partition in other embodiments there are more or fewer read tasks than sort tasks and more or fewer sort tasks than logical partitions similarly the number of write tasks may be equal to less than or greater than the number of sort tasks it has been found that in some environments matching the number of sort tasks and the number of write tasks that is associating one write task to one sort task during the operations of block 245 reduces dasd write back conflicts one of ordinary skill in the art will recognize that the use of multiple read sort and write tasks coordinated through the logical partition of a target data object 39 s.
