Ive heard Bugzilla can be used with Oracle?
Red Hat’s old version of Bugzilla (based on 2.8) worked on Oracle, but it is now so old as to be obsolete, and is totally unsupported. Red Hat’s newer version (based on 2.17.1 and soon to be merged into the main distribution) runs on PostgreSQL. At this time we know of no recent ports of Bugzilla to Oracle; to be honest, Bugzilla doesn’t need what Oracle offers.

At this time we know of no recent ports of Bugzilla to Oracle but do intend to support it in the future (possibly the 2.20 time-frame).
