Answer 1

Normally, you can use a lower version to export. That is not best practice
but people do it.
For example , the DBA does a full client install of 9.2.0.1 on his Windows
desktop and uses that to run exp against a 9.2.0.x database on a Unix/Linux
server. People do that. Although that is not the proper thing to do.
Also, if you need to export from one version and import into a lower version,
you do need to use the exp utility of the lower version.
However, in this particular case, the Notes I mentioned identify this as a bug
which is a regression after the 9.2.0.5 patchset fixed another issue with
dba_segments. So, now you have to use 9.2.0.5 or higher as your exp utility.
It is, of course, always best to run exp from the same ORACLE_HOME as
the database. But best practices aren't always practiced in the real world !
