Read access to a schema!!!

Question

Hi GUys,
I am using oracle 10.2.0.4.0 on windows server 2003. I have a silly question as I am new to oracle. I have a schema call SAT and SATREAD. I have to give read only access TO SATREAD on all tables and views in SAT. I did the following :
GRANT SELECT ON TABLENAME TO SATREAD;
After this I logged in as SATREAD and did
select * from tab;
and I get no rows selected. But when I do
select * from tablename then I get the correct resultss. Any Idea on how to see tablename listing in SATREAD schema.
I also did the following but not sure what I did was right:
SAT> create public synonym test for test; ---test is a name of table in SAT schema
Synonym created.
SAT> grant select on test to public;
SAT> conn SATREAD/******
Connected.
SATREAD> select * from tab;
No rows selected
Thanks

...All I want is when the end users log into SATREAD schema and do select * from tab, they should see all the tables from SAT schema.That's not possible. I'm not sure if you read my post above, but TAB should not be used, and I'm still wondering why you are looking into that TAB view.
TAB is a view selecting objects for your own user you are connected with (like USER_TABLES), consequently you cannot see tables owned by others.
See :
SQL> select text from dba_views where view_name='TAB';
TEXT
select o.name,
      decode(o.type#, 2, 'TABLE', 3, 'CLUSTER',
             4, 'VIEW', 5, 'SYNONYM'), t.tab#
  from  sys.tab$ t, sys.obj$ o
  where o.owner# = userenv('SCHEMAID')
  and o.type# >=2
  and o.type# <=5
  and o.linkname is null
  and o.obj# = t.obj# (+)
SQL>It makes clear than SCHEMAID is yourself and objects return are only your own objects. So, what you are looking for is not possible until you use the proper views.
