While trying to open the TN (in 6.1),its giving the error of Broken Pipe exception.The full error is given below:

Error querying documents: java.sql.SQLException: [wm-cjdbc33-0069][Oracle JDBC Driver]Broken pipe. Original SQL: SELECT

WHERE
d.DocTypeID = t.TypeID AND
d.SenderID = s.PartnerID AND
d.ReceiverID = r.PartnerID AND
d.DocTimestamp > {ts ‘2007-06-17 00:00:00.0’} AND
d.DocTimestamp < {ts ‘2007-06-18 00:00:00.0’}

(0) java.sql.SQLException: [wm-cjdbc33-0069][Oracle JDBC Driver]Broken pipe
(1) java.sql.SQLException: [wm-cjdbc33-0069][Oracle JDBC Driver]Broken pipe

Can anyone please suggest a solution for the above problem?

I had similar error when the TN database was down. test it from the JDBC Pools page.
