Connecting to the SAP System

The connection to SAP is managed within the proxy’s connection object. You do not have to determine the status of the connection yourself as the connector manages this automatically. Before an RFC can be executed, the connection must be opened. After the RFC has finished executing the connection should be closed. 

For applications that have many concurrent users, the connector provides a connection pool object. It is possible to get the connection from the pool instead of creating one for each client. In this way connections are reused and performance is improved.
