Connection string log messages
Hi David,My only issue is with the term "Physical Connection".Connections are logical, not physical. Ethernet cables, adapters, wires, RAM, disk drives are physical. Ports, sockets, connections, database tables and columns are logical.I really don't like using physical to describe the lowest level of connection. Isn't there another term that conveys the correct information, like Hard Connection, or Socket Connection, Port Connection, or simply Connection?CraigHere is an adjusted proposal, taking into account Kathey's *and Dan's* comments :)[ ] VOTE on toString() format for Derby embedded connections(a) Physical Connections, Pooled Connections (EmbedConnection, EmbedConnection30, BrokeredConnection, BrokeredConnection30): classname@hashcode (DATABASE = dbname), (SESSIONID = sessionid), (DRDAID = drdaid), (XID = xid)Example: [EMAIL PROTECTED] (DATABASE = wombat), (SESSIONID = 1), (DRDAID = null), (XID = 105)(b) Pooled Connections (EmbedPooledConnection, EmbedXAConnection): classname@hashcode (ID=uniqueid), Physical Connection=underlying connection stringExample: [EMAIL PROTECTED] (ID=2), Physical Connection = [EMAIL PROTECTED] (DATABASE = wombat), (SESSIONID = 1), (DRDAID = null), (XID = 105) Craig Russell Architect, Sun Java Enterprise System http://java.sun.com/products/jdo 408 276-5638 mailto:[EMAIL PROTECTED] P.S.

'physical connection' is the term used by the JDBC 3.0 spec, so I think it is the correct term to use here. In the embedded case the physical connection does not use a socket or a port so using such terms would be misleading. Dan.
Re: Connection string log messages
I don't need to use the term; I can just call it a Connection. This doesn't really impact the resulting code, just what we put into the comments and the JIRA bug. BTW, if you want to get picky, nothing is physical -- from the perspective of quantum physics, it's all a mass of probability. :) David Craig Russell wrote: Hi David, My only issue is with the term Physical Connection.

Re: Connection string log messages
Hi David,I don't need to use the term; I can just call it a "Connection". This doesn't really impact the resulting code, just what we put into the comments and the JIRA bug.I understand. Perhaps it would be more useful to avoid "physical" and use either Embedded or Network, as in "Network Connection" and "Embedded Connection".BTW, if you want to get picky, nothing is "physical" -- from the perspective of quantum physics, it's all a mass of probability. :)The point is that I am picky about terms. :-) And let me know next time you stub your toe on a bit of probability...CraigDavid Craig Russell Architect, Sun Java Enterprise System http://java.sun.com/products/jdo 408 276-5638 mailto:[EMAIL PROTECTED] P.S.
