SELECT grants are provided directly (do I need more then select?) - I've
just checked it.
If schema TARGET has its own private link then all goes well, if not
then while creating a mview the rdbms throws
00942. 00000 -  "table or view does not exist".

This error is when in the view in the MIDDLE schema there is no
qualification (ie. there is from some_view@SRC and not
some_user.some_view@SRC). If I add it then I 've got
04052. 00000 -  "error occurred when looking up remote object %s%s%s%s%s"

thus it seems that when I call the MIDDLE view from TARGET session in a
query, it is done entirely on MIDDLE objects, but when I try to build a
mview the definition is somthing like copied to the mview definition and
then performed - then in a wrong context.
