Do you want to save reduced data?

If you want to keep historical Accounting and Statistics data about DB2 performance, consider using REDUCE and SAVE.

This processing has advantages and disadvantages. Reducing and saving data uses a considerable amount of system resources, but the resulting Save data set is much smaller than the original input data set. The size of the resulting Save data set varies with the specified reduction interval and the type of environment the data is from (for example, the number of different users and plans present in the input data).

You can produce reports from the reduced and saved data by using the RESTORE command. Remember that you cannot produce traces from reduced data.
