Do you mean "repack your data set" as in using Adager/Dbgeneral to
reorganize the data set (which I can't do in a 24x7 environment)?
Or "repack your data set" as in delete all entries while writing
them to a flat file, sort the flat file, and then add the records
back in (which I can do, but I don't think it will reset the high
water mark)?

You can use either "repack" you mentioned.  If you delete all entries, the
highwater mark and deletechaincount are both set back to zero.  Of
course your applications may have a cow about the temporarily missing
data.
