Explanation

This is an informational message to report the copy statistics. This message is issued by the following utilities:

• COPY
• LOAD, if a full image copy has been requested during a table space load
• REORG, if a full image copy has been requested during a table space reorganization

The statistics apply to pages that are included in the scope of the COPY request: a full table space, a full index space (DSNUM(ALL)), or a partition (DSNUM(integer)). All of the pages in the table space, index space, or partition can be copied (FULL(YES)), or only the changed pages can be copied (FULL(NO)).

csect-name

The name of the control section that issued the message.

object-type

The type of object.

object-qualifier.object-name

The name of the object, as a qualified name.

total-pages

The number of pages written out. The number of pages written includes valid instances where pages are written more than once, or for incremental copies, pages written which have not changed since the last copy was taken. A slight discrepancy between this value and the actual number of pages is possible and is considered normal.

free-space

The average percentage of free space within the copied pages, in the format nn.nn. This value indicates the amount of change activity that can occur without significant impairment of reference performance.

This value is 0 for sequential copies made from a FlashCopy®.

changed-pages

The percentage of changed pages, to two decimal places (nn.nn or 100.00). This value indicates the amount of change activity that occurred since the last image copy or reorganization. The percentage of changed pages is obtained by dividing the number of changed pages by the number of pages in the object. Preformatted pages consisting of all zeros are included in the count of pages scanned. Because these preformatted pages are not copied to the output data set, the number of pages scanned is usually larger than the number of pages copied.

When this message is issued for image copies produced during LOAD or REORG, this percentage will always be reported as 100.00 (100%), because the utility is resetting and reformatting the entire table space.

This value is 0 for sequential copies made from a FlashCopy.

hh:mm:ss

The elapsed time, shown as the number of hours, minutes, and seconds.
