Depending on whether the database lock it uses is acceptable or not,
the simplest answer is to dbexport the original database and dbimport
it - possibly afer renaming it.   If you only need the schema and not
the data, then dbschema and dbaccess will do the trick.  You could
also consider onunload and onload.  Art Kagel has a program, myschema,
which does a pretty good job of schema replication - and myexport and
myimport, which are scripts that use myschema and sqlcmd.  All that's
available from the IIUG software archive.
