Actually, I can just compare with the embedded derby system : it is a little longer to import xml in the JCR (typically when bootstrapping), but quicker to read the datas (typically, when using the app!). The "how to install DataSourcePersistenceManager" is not yet written in the wiki (and if someone wants, no pb, feel free to update !), but I said all that is necessary I think in the user mailing list, thread "A jackrabbit PersistanceManager which not use only one Connection".

Cheers,
   Anthony

How's the performance on MySQL? I heard it was pretty bad with the DataSourcePersistenceManager.

Alternatively, you could use a database like MySQL, and the 
DataSourcePersistenceManager ...

Ok, based on Pascal's last email, it looks like I can't go this route.
My goal is to create a Tomcat / Magnolia CE bundle that uses a BDB storing blobs in the database. Is that possible? I was almost to the point of being able to deploy a Tomcat/Magnolia bundle without building any code.

If you are using magnolia dbd persistence distributed with enterprise edition then only you can change binary store. if you have this jar, to make it work without compiling you can override properties file under classes

create a file bdb.properties under classes/info/magnolia/state/berkeley
with a single property stating the store

blobStoreType = db

and bootstrap, from now on it will store all binaries in database.

Not yet. We're trying to get BDB running on 3.0 CE first. We plan to move to Oracle and 3.0 EE early next year. In the meantime, are you saying we cannot change the blob storage in the Tomcat Magnolia bundle
CE version?

Hi Ben,

are you are using magnolia enterprise? if so you can contact magnolia support we can build it for you. if you are enterprise customer and have access to the enterprise SVN then you need to change bdb.properties under resources

----- from bdb.properties --------------------- # blobStore can be either db (database) or fs (filesystem) blobStoreType = fs

currently this is a compile time flag and cannot be changed later on once built this property file is packaged with the jar under info/ magnolia/state/berkeley


Hope this helps

The Enterprise Edition instructions include the below step, but no instructions on how to do so. I think this change may fix my "too many files open" problem. Does anyone know specifically how/what to change?


4. Set BLOB storage
- by default all binaries are stored on file system for performance reasons, but you can change this behaviour
        and force binaries to store in berkeley database.
NOTE : This is a compile type configuration and must be changed while building the connector and can
        only be applied on an empty repository.

Thanks in advance,

Ben
