JDBC Connection to Teradta 14 best practices for high volumn.

To whom it may concern,
The dev team here are trying to implementing the solution for publishing medium/high volumn of the data into Teradata database (insert and update statements @ around  /hour) via jdbc transaction.
The connection string that's used is normal JDBC Connection string:
e.g.
jdbc:teradata://STETSTADWAPP02/Database=D101_PROC_APP without any parameter append at the end of the string.
 
The main problem that we are currently encountered is:
- The database table dead lock (according to the Teradata team, this could be due to the insert/update statement doesn't close the session)
 
Here I am after the best practice of the jdbc connection string for teradata and try to explore the way how can the connection pool and the session can be controlled.
Best,
