The “tora” database client package in Feisty Fawn comes with Postgres support, and MySQL if you have the libraries. This How-To shows you how to build Oracle Instantclient 10g support into tora.
This is client only. You will not install the whole Oracle database.
BTW, if you don’t have time to build the whole thing, here is the .deb package I built using this How-To. It’s x386 only, and you’ll need to have instantclient installed before you can use it.
tora_1.3.22-5_i386.deb is an updated .deb package for instantclient 11.1.0.1 and tora 1.3.22.
