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.
