I found myself with a little unexpected time at work recently, and since we use Oracle (for a few more months), I decided to port Sqitch. Last night, I released v0.970 with full support for Oracle. I did the development against an 11.2 VirtualBox VM, though I think it should work on 10g, as well.
cpan install App::Sqitch DBD::Oracle
brew tap theory/sqitch brew install sqitch-oracle
Via ActiveState PPM, install ActivePerl, then run:
ppm install App-Sqitch DBD-Oracle
There are a few other minor tweaks and fixed in this release; check the release notes for details.
