RE: [Hibernate] Re: [JBoss-dev] switch to derby in JB5?
There maybe some setting we are just missing for test purposes. For example, I don't know about you, but on my Oracle setup I disable recovery logging on the datafiles backing my test schema. Without disabling this option, it is painfully slow to run the testsuite against Oracle; and obviously I don't care about recovery of my test data ;).

Re: [Hibernate] Re: [JBoss-dev] switch to derby in JB5?
Hi, The JVM wide system property derby.system.durability to the value true does just that (recommended by the Derby crowd).
