This is server side Manmath – often a Teradata instance will terminate idle connection, speak to your DBA about changing this.

The new connections are working fine but if I am trying to use the same connections next day, I am getting the below error. [Teradata JDBC Driver] [TeraJDBC 13.10.00.29] [Error 1095] [SQLState HY000] Cannot call a method on closed connection I am not sure but I thing this might be because of the connections getting dead after some ideal period. Please help me on this if anybody has ever faced this problem or know how to fix this. Thanks & Regards, Manmath
