Hello.
I have read codes around impl.drda.Session and found they have something to do
with DRDA protocol.
In the specification of DRDA found in open group's site (http://www.opengroup.org/bookstore/catalog/dm.htm) told
that DRDA protocol provide connection architecture as next :
2.3 DRDA Connection Architecture
Connectivity in support of remote database management system processing
requires a
connection architecture that defines specific flows and interactions that
convey the intent and
results of remote database management system processing requests. DRDA
provides the
necessary connection between an application and a relational database
management system in a
distributed environment.
I think impl.drda.Session stands for connection defined in DRDA protocol.
Programmer might made effort to distinguish the word from java.sql.Connection
...
Best regards.

Subject: Re: Difference between Session and Connection.
My understanding from working with this code is that a Session on the
Network Server is a one-to-one correspondence with a Connection on the
Network Client. They are the two endpoints of the same communication
channel.

Hello.
I had found a class org.apache.derby.impl.drda.Session
(http://incubator.apache.org/derby/javadoc/engine/org/apache/derby/impl/drda/Session.html)
It seems that there exists concept of Session in Derby.
However, I'm not sure difference between Session and Connection ...
It seems very same but sence some difference ....
//I imagine Session may be concept which exists only in drda module ....
Does anyone know the certain imformation ...?
Best regards.

Make it clear the difference between EmbedConnection and Networked Connection
-----------------------------------------------------------------------------
Key: DERBY-458
URL: http://issues.apache.org/jira/browse/DERBY-458
Project: Derby
Type: Task
Components: Network Server, Network Client
Reporter: Tomohito Nakayama
This is question found in DERBY-397.
There must be significant difference between EmbedConnection and Networked
Connection.
What is the difference between them ?
It is a significant characteristic of Derby to have EmbedConnection.
Then, this difference will have special meaning in development of Derby ...
I think we should discuss in ML ....
