Answer 1

You mean that I can install isqlplus from oracle9i into my oracle8.1.7.You would need to install into a new Oracle9i-only directory (i.e. a
new ORACLE_HOME). The iSQL*Plus in it would be able to connect to
your existing 8.1.7 database using Oracle Net.
Unfortunately I see 9i is not supported on Solaris x86 (though 10g is
"projected".)
The French iSQL*Plus 8.1.7 document you refer to talks about the first
pre-production version of iSQL*Plus released. It cannot be
recommended for use, and is no longer available.
