The Database Restore orders for maximal Access Path sharing as well.
Thus even if LFA had been created before LFB and saved onto media
wherein the SAVLIB [or SAVOBJ] had included saving of both of those
Access Paths which were valid, compatible attributes, and compatibly
maintained, then the RSTLIB [or RSTOBJ] would actually restore LFB first
to enable the compatible LFA [i.e. same equal\duplicate-key ordering
rule, LIFO, FIFO, FCFO] to share the keyed access path of LFB... thus
limiting the required storage and maintenance from two AccPth to one.
So... Yes, the DBF restore feature will indeed be smart enough to
preserve that, as well as /smart enough/ to possibly /enhance/ that;
i.e. such that to maintain non-shared, explicit means must be taken to
prevent sharing. The restore ordering may even be done according to
definition [I do not recall], such that the actual existence of access
paths on media is moot, in order that potential eligible sharing is
established irrespective of actual ability to share upon the load [of
data and access paths] after create-for the restore; i.e. the DB restore
is accomplished by /create/ of the objects followed by placing the data
from media into the pre-created objects.
