Hibernate version:2.0

Name and version of the database you are using:mssql 2000

Sometimes when I execute session.getConnection(),hibernate will connect to db again and
hibernate will warm me that database changed to XXX.
Why?
I use ThreadLocal to manange a same db session.
SessionFactory is singleton.
When I close connection ,I execute connection.close() and remove session from ThreadLocal .
One of my servlets invoke 20 database,if one of databases appears this hibernate's warm,servlet's speed will be much slow.

its is the driver that sends that warning, not hibernate.

session.getConnection() means jdbc.getConnection()?
why often warn?
Another thread closed Connection due to reset to connect to db?

if one thread get Connection from session ,another get a same Connection, one thread execute con.close(), what happen on another thread's connection? will reconnect?

again - its the database that says it.

Im guessing you are using ms jdbc - go on their forums and ask why they report this warning each time you connect.
