Chapter 3. Operating NetView FTP V2.2.1 MVS - IBM

If an error occurred while processing one of these steps, the corresponding
error handling mechanisms are started. Specifying the function code COPY
means to transfer a file between the local and the remote system. After a successful
copy, the file is stored in MVS and registered in the OSI/File Services
filestore at both the sending and receiving systems.
3. After OSI/File Services has finished the transfer, the result is available at the
OSI/File Services interface (success or failure of the transfer). The OSI server
converts the format of the result to the format needed by the queue handler,
and then passes the result to the queue handler. Therefore, OSI/File Services
terminology is used in some situations rather than NetView FTP terminology.
4. Further processing is done asynchronously. After one request is passed to
OSI/File Services, the OSI server is ready to process the next request. This is
done independently of completion of the previous request.
5. When an OSI/File Services activity is completed, the result is available via the
GET_RESULT command at the OSI/File Services interface. The server keeps
the information necessary to obtain the result, and continues processing the
current request. For further information, refer to either the OSI/File Services
System/370 Programming Guide or the OSI/File Services System/370 User’s
Guide.
6. The OSI server asks for the result in the next processing cycle. The result of
the transfer includes detailed information about the success or failure of the
transfer, and the number of bytes transferred. This information is passed to the
queue handler.
If the function specified is MOVE, the same steps as for function COPY are performed
to process the MOVE request. After a successful MOVE:
� The file is removed from the sending system
� The file entry is removed from the filestore at the sending system.
Stopping NetView FTP V2.2.1 MVS Running
You stop NetView FTP V2.2.1 MVS running by stopping the queue handler using
the STOP command.
When you stop the queue handler, all running servers are stopped immediately.
The file transfers that are currently being processed are interrupted and checkpoints
are taken for the SNA file transfers. When you restart the queue handler,
any file-transfer request that specified automatic transfer restart is rescheduled
when a server that serves its request class becomes available.
You can also stop the queue handler by stopping the server first, using the
MODIFY command, and then stopping the queue handler. The file transfers that
are currently being processed are either completed or not, depending on the
command options you used. For further information, refer to Chapter 3, “Operating
NetView FTP V2.2.1 MVS” on page 43.
