Hi, I updated the GOODS backend for SandstoneDb to work with Pharo 1.2, and I fixed a few bugs related concurrent access. To download and test it: Gofer it squeaksource: 'SandstoneDb'; package: 'SandstoneDb'; load. Gofer it squeaksource: 'BTree'; package: 'Collections-BTree'; load. Gofer it squeaksource: 'GOODS'; package: 'GOODS'; package: 'GOODSPlatformSqueak'; load. Gofer it squeaksource: 'SDGoodsStore'; package: 'SandstoneGOODS'; load Start GOODS on localhost:6000, and restart your image. I also wrote a blog post about it (the first part of the post) http://nicolas-petton.fr/2011/04/15/load-balancing-iliad-applications.html Cheers, Nico -- Nicolas Petton http://www.nicolas-petton.fr
