That works well for small schemas. It tends to generate a

This number varies with how intensely RI was implemented.

This is a bug in sqlplus. You are using two different releases Oracle,
and when you are using the 8i version of sqlplus and trying to describe
a table on a lower version of Oracle through a dblink, you will get this

The work around is: Don't do that. Seriously. It's not fixed,
