is there a pressing NEED for installing a unsupported database
9 became unsupported back in 2010
and was released in 2001
the current Oracle DB in 12
and it is unlikely that the antique 9i will install with the current jvm 1.7
look for the also rather very old java 1.3
from the now no longer around SUN microsystems
