Hi, im stunned, yes, i did use the wrong jndi binding it seems ... it's an error kept from my first day with orion ... All i wanted was already in there ! The performance is nearly the same as with my foolish caches.... Thanks a lot, Jens Stutte -----Ursprüngliche Nachricht----- Von: Magnus Stenman [mailto:[EMAIL PROTECTED]] Gesendet am: Samstag, 1.

Are you by any chance using the raw DataSource by mistake? >From inside user code you should use the source specified by ejb-location (will be renamed to cmt-location since ejb-location is a bit misguiding when it's used from servlets etc too). Look at the data-sources.xml's documentation for pooling settings (timeout, max-connections and so on). Also - if performance is important CMP is recommended since it generally yields better performance (only use BMP when it is really, really needed). /Magnus Stenman, the Orion team
