Copying the data set attributes

After copying the data set attributes, all data set records of the target data set make the data set appear to be the source. DFSMSrmm copies all attributes that are not related to the physical aspects of the data set, volume, and tape drive.

Note:

Those attributes related to retention are subject to update by the next run of inventory management. The intention is that the copied data set will be retained in the same way as was the source data set. The actual results depend on the retention methods and policies used.
When you use the CHANGEDATASET COPYFROM subcommand operand, the last user change date and time information of the target data set is also updated during command processing to reflect that the command was processed.
After the attributes are copied, there will be no trace of the copy application or the batch job used to perform the copy, because all target data set attributes reflect the creation and use of the source data set. However, the last change information reflects the time the COPYFROM was done.

Table 1 identifies data set attributes that are not copied or are copied only in certain cases. For each attribute, it lists the CHANGEDATASET operand (if any) that can set this attribute and the extract file field and REXX variable (if any) for that attribute.
