10g downwards compatibility

After installing 10g I find that some things are different. Especially I had to rely on O7_dictioniary_accessibility=TRUE on init.ora.

The parameter is understood. But still I have problems with the SYS user. Seems I cannot run an SQL script under user SYS any longer that creates some Views on SYS.all_tables or something in that vein.

How can I get 10g to behave more 9i or 8i like?
