Re: [gatein-dev] Portal and page names and case sensitivity

Moreover, I'm pretty sure that it will create side effects more painful than case sensitivity issues. The only way to solve this problem is to specify clearly in the doc that the database must be case insensitive. Can this be set at DB level ? I thought it was at table level ? And since tables are created by JCR it's a bit tricky. We're going without any change, it's not as bad as I originally thought it was, I'm still curious about the possibilities though.
