---------------------------------------

Great work with the thorough use-cases, Fernanda. =20

I suggest to go for an implementations where locators work on copies and no=
t directly on the LOBs.  Working directly on a LOB can change the behavior =
of current applications since updates may occur without a call to updateRow=
().  Hence, applications which sets parameters and then for some reason ski=
ps updateRow(), will experience a changed behavior.  Also, it seems like th=
e infrastructure for working on a copy will be needed anyway in order to te=
mporarily store LOBs that have not yet been assigned to a row.

> Currently Network Server materializes all LOB objects.  LOB locator suppo=
rt is part of the DRDA spec so could be added to network server.  See

> It is not clear if SQL Support for LOB locators would also be required.
