Event Flow from an FTP File Transfer Service

How events flow from an FTP server to CA NetMaster FTM depends on the underlying TCP/IP mechanism:

• CA TCPaccess CS for z/OS
• CA TCPaccess FTP Server for z/OS
• IBM's Communications Server

Event Flow from CA TCPaccess CS for z/OS

The following diagram shows the flow of events from an FTP server on CA TCPaccess CS for z/OS to CA NetMaster FTM if you are not using CA TCPaccess FTP Server for z/OS:

CA NetMaster FTM provides an SMF exit, IPSMFEX. The exit forwards FTP events to a receiver by using the event delivery facility. CA NetMaster FTM listens to that receiver for the events. The FTPCNTL parameter group controls whether that receiver is enabled.

The SOLVE SSI task that provides the event delivery facility is specified in the CA NetMaster FTM SSI parameter group.

Event Flow from CA TCPaccess FTP Server for z/OS

The following diagram shows the flow of events from the CA TCPaccess FTP Server for z/OS to CA NetMaster FTM if you are using CA TCPaccess FTP Server for z/OS:

CA TCPaccess FTP Server for z/OS forwards FTP events to a receiver by using the event delivery facility. CA NetMaster FTM listens to that receiver for the events. The FTPCNTL parameter group controls whether that receiver is enabled.

The SOLVE SSI task that provides the event delivery facility is specified in the CA NetMaster FTM SSI parameter group.

The CA TCPaccess FTP Server for z/OS policy rule sets and rules let you control the use of FTP functions. A rule set containing the policy rules must be defined for your CA NetMaster FTM region.

Event Flow from IBM's Communications Server

The following diagram shows the flow of events on IBM's Communications Server to CA NetMaster FTM:

CA NetMaster FTM provides an NMFTP Monitor SSI. The SSI exploits IBM's network management interface to obtain FTP file transfer-related SMF records and forwards the events to a receiver by using the event delivery facility. CA NetMaster FTM listens to that receiver for the events.

Note: The FTPCNTL parameter group controls whether the receiver is enabled.

The network management interface does not recognize termination failures if the file transfer does not start; therefore, the FTP post-processing exit, FTPOSTPR, is used to provide these missing events.

The SOLVE SSI task that provides the event delivery facility is specified in the CA NetMaster FTM SSI parameter group.
