Hi Tom, ok, I did that. I read the parameters for the database (protocol, subprotocol, ...) from database_repository.xml. Then I try to establish a connection to the DB. If that fails the DB is not available.
You don't think this could be a functionality that PB API could provide? Frank -----Ursprüngliche Nachricht----- Von: Thomas Dudziak [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 19.

I think that in JDBC you'd have to try to establish a connection to it and if that fails, then likely the database is not available (for whatever reason). AFAIK there is no other generic way (though individual databases may provide other means). Since OJB builds upon JDBC, you probably got to try to establish a connection and execute the query that you've defined as the keep-alive query, and see whether this is possible.
