If you wish to upgrade in place from Oracle 7.3.4 to Oracle 10g (either release 1 or 2), you must first upgrade your 7.3.4 database to 126.96.36.199, and then you can upgrade to Oracle 10g.
How you upgrade depends on many factors – disk space, physical memory on the server, etc. A good source of information is the Oracle documentation on Oracle's Technology Network Web site.
