Using MERGECOPY with individual data sets

Use MERGECOPY on copies of an entire table space, on individual data sets, or on partitions. However, MERGECOPY can only merge incremental copies of the same type. That is, you cannot merge incremental copies of an entire table space with incremental copies of individual data sets to form new incremental copies.

About this task

The attempt to mix the two types of incremental copies results in the following messages:

DSNU460I DSNUBCLO - IMAGE COPIES INCONSISTENT.
                    MERGECOPY REQUEST REJECTED
DSNU010I DSNUGBAC - UTILITY EXECUTION COMPLETE,
                    HIGHEST RETURN CODE=4

With the NEWCOPY YES option, however, you can merge a full image copy of a table space with incremental copies of the table space and of individual data sets to make a new full image copy of the table space.

If the image copy data sets that you want to merge reside tape, refer to How the RECOVER utility retains tape mounts for general information about specifying the appropriate parameters on the DD statements.
