RE: granting SELECT privilege on SYS.X$ TABLES

P.S. I forgot to mention that in all the databases (including the 8.1.7 databases) in which I tried this, init parameter O7_DICTIONARY_ACCESSIBILITY was set to FALSE.

I always thought that one could not grant SELECT privilege on the SYS.X$ tables, and to make them accessible to another user one would have to create a view on the table (as mentioned on Steve Adams' ixora website: create_xviews.sql)

However someone told me recently that you could grant SELECT on sys.X_$...

When I tried this, I saw results that confused me. In Database A, Oracle, Windows 2000 server, I was able to

1- grant select on SYS.X_$KTFBFE to another_user ;
2- grant select on SYS.X_$KTFBHC to another_user ;
3- grant select on SYS.X_$KTFBUE to another_user ;

BUT 4- grant select on SYS.X_$KDXST to another_user ; returns ORA-00942 table or view does not exist.

In database B, using the same ORACLE_HOME as database A (i.e. identical Oracle version and OS) even the first three grant statements returned ORA-00942

When I tried it on more recent Oracle databases on Windows / SunOS servers, it worked intermittently: Oracle 9.0 (SunOS): all GRANTS failed
Oracle 9.2 (SunOS): GRANTS 1-3 were successful, GRANT 4 failed Oracle 10.1 beta (Windows 2000): all GRANTS failed

Does anyone know the reason for this strange behaviour?
