Hi,
In webdybnpro ,each Model in an Application utilizes a seperate Connection.If u create JCO connection pool for the User then while connecting to backend
1)The JCO connection pool Manager will open a new connection pool and opens the first connection.
The next available connection from the pool is allocated to the model object.
2)The model object is now able to invoke the required functionality in the ABAP system.
3) When the connection is no longer required by the application, it is returned to the pool.
4) The connection remains logged on to the backend system until either the next application
request is received, or the connection timeout is reached.
5) If no application requests arrive before the timeout is reached, the connection is flagged
for closure.
Note:-If an Application contains 2 models which are connecting to same ABAP system then second Model can be told to share the same JCo connection used by First model This is done by calling its setConnectionProvider() method.
