[jira] [Commented] (ISIS-2651) JDO bootstrapping for h2 seems to only lazily create tables. For reliability, create all up-front.

Daniel Keir Haywood commented on ISIS-2651:
-------------------------------------------

datanucleus.generateSchema.database.mode=create is the secret sauce.

 

Also note that we dynamically create the persistence unit, as per [1], but even so this config prop is ALSO required.

> Our updated JDO integration no longer seems to eagerly create tables on bootstrap, instead creates them when first accessed.
> With our previous integration, this proved to be an issue with superclass tables when DN didn't have the full meta-model to hand.  It would be safer to create all up-front.
