Re: DB schema migration
Hi Erik, Took a look at this - it's not actually the jpox tables (we don't use the pre-configured schema), but problems when we turn on autocreation: In an ALTER TABLE statement, the column 'INTEGER_IDX' has been specified as NOT NULL and either the DEFAULT clause was not specified or was specified as DEFAULT NULL. we also have (which is probably because of our metadata): In an ALTER TABLE statement, the column 'CHANGEDATE' has been specified as NOT NULL and either the DEFAULT clause was not specified or was specified as DEFAULT NULL. So I think I'm going to do the migration tool. - Brett On 24/04/2007, at 7:35 AM, Erik Bengtson wrote: Quoting Brett Porter [EMAIL PROTECTED]: Erik - the problem in upgrading is the changes in private tables between versions of jpox that we hadn't given explicit names to. We'd probably appreciate most help in future proofing our jpox use a bit more in case it's internal schema changes again. If you mean by private tables the JPOX_TABLES, you can drop it and JPOX will automatically recreate if it's needed.

Hopefully it won't change too much, but it should in no way stop the developers from breaking stuff. I agree. What is important here is the ability to dump the database to an external DB file (xml would be a natural choice) which can be read by a newer Continuum. As soon as this is in place, I'll migrate. Cheers, Stéphane Hopefully 1.1 will be pretty stable so it can be released ASAP and bugs can be fixed on a 1.1.x branch. -- Trygve Thanks, Stéphane On 4/23/07, Brett Porter [EMAIL PROTECTED] wrote: This was one of the things I was going to try and have done before alpha-1 - I just forgot.

Thanks Erik - I'll give that a try ASAP.

RE: DB schema migration
Sounds like this is the answer to my question: Should I start fresh with alpha 1.1? I got nightly build continuum-20070317.00.war to work with Jboss 4.0.5.GA, but I couldn't get the nightly build: continuum-20070418.03.war to work, even when I followed the same instructions at http://docs.codehaus.org/display/CONTINUUMUSER/Continuum+on+JBoss I only have 2 projects so far so seems it would be good for me to start fresh with alpha 1.1.

Re: DB schema migration
The problems Stephane has is because of the JPOX upgrade, not the schema changes we've made. I'm not saying it won't be possible to migrate from 1.0.3, it just won't come out of the box (or necessarily be ready by the time the release goes out). - Brett On 23/04/2007, at 9:00 PM, Jesse McConnell wrote: any remaining changes in 1.1 will at _most_ be additive in the form of a boolean value here or there for some improvement, there should be no more changing of column names or anything of that ilk...Those were taken care of in one fel swoop when we fixed things up to remove potential DB keyword conflicts jesse On 4/23/07, Stephane Nicoll [EMAIL PROTECTED] wrote: Can I be sure at least that the DB model won't change as from alpha-1?
