Understanding Communication
•ADO uses the Connection Object to communicate with the AS/400. •Like ODBC and JDBC, OLEDB talks to the QSERVER subsystem, (QUSRWRK on V5) •A connection causes a pre-start job, QZDASOINIT, to be used. The QZDASOINIT job will stay alive until the connection is closed •The QZDASOINIT job is returned to a pool, and then reused by a subsequent connection.
