Defining sort work data sets

To improve the performance of Log Master sort actions, use one of the techniques described in this section to control the allocation. If you do not allocate enough sort work space, or if you place the sort work data sets on different units inefficiently, Log Master can perform at less than optimum levels.

You can also use the following methods to affect the performance of sort actions:

• You can control how much memory Log Master allocates for each invocation of the sort routine. For more information, see SMCORE=0M,0K.

• You can estimate the amount of data to be sorted and pass that estimate to the sort routine. For more information, see  Sort file size parameters.
