Usage Notes
For FTP, if the returned Allow operation output parameter is not valid, the FTP
application will not allow the operation and the message “Data from exit program for
exit point &1; is missing or not valid” will be issued to the job log.
For FTP, if any exception is encountered when calling the exit program, the FTP
application will issue the message: Exception encountered for FTP exit program
&1; in library &2; for exit point &3;
Two different exit points are provided for the FTP application. Exit point
QIBM_QTMF_CLIENT_REQ is used to validate requests processed by the FTP
client program. Exit point QIBM_QTMF_SERVER_REQ is used to validate requests
processed by the FTP server program. If desired, the same exit program can be
used to validate requests from both of these exit points.
Table 80 summarizes the operation-specific information required for each operation
identifier.
