General J2EE: In-memory databases

  1. In-memory databases (3 messages)

    I try to speed up our JUnit tests. They often involve persisting and retrieving data from our Oracle database.

    Because we use CMP, this process is slow.

    I read about in-memory databases like Cloudscape. But it is not a free product. Is there a free alternative?

    Does Oracle provide such a in-memory support?

    What do you think about the in-memory persistence approach?

    Are there any good tutorials or best practices for it in the context of J2EE/CMP?

    Hi Hans,

    It is neither free or a database but this is exactly the issue that most of our customers use Coherence to solve. The cache can be 'bound' to a database for read-through and write-behind of the data.
