init parameter

[@more@]

The O7_DICTIONARY_ACCESSIBILITY initialization parameter controls restrictions on system privileges when you upgrade from Oracle7 to Oracle8i and higher releases. If the parameter is set to TRUE, access to objects in the SYS schema is allowed (Oracle7 behavior). If this parameter is set to FALSE, system privileges that allow access to objects in "any schema" do not allow access to objects in SYS schema. The default for O7_DICTIONARY_ACCESSIBILITY is FALSE.

When this parameter is not set to FALSE, the ANY privilege applies to the data dictionary, and a malicious user with ANY privilege could access or alter data dictionary tables.
