I have an application using SYBASE with JBOSS and TORQUE, and have been monitoring the database connections used in the jmx-console. When a user only views information, they only use one connection, however when they update or insert they use two.

Can anyone point me to why this is the case? Is it specific to J2EE , SYBASE, TORQUE, JBOSS or the pool we are using?

Any help in finding documentation to why this is the case is appreciated.

Thanks,
