The Question is: I am running OpenVMS Alpha version 7.2-1 with Digital TCP/IP Services 5.0A. I have a program that populates a directory with a bunch of files that get FTPed to a server everyday. I want to delete the files that are successfully FTPed, but I do not see a way to determine which ones were successful or unsuccessful without restarti ng FTP everytime. Establishing a FTP connection everytime is very inefficient and timing is somewhat critical. We used to use TCPware instead of DIGITAL TCP/IP Services and I was able to use an ERROR_EXIT n (n is the file number that I was on) to determine which file I failed on. This was very helpful so I could be certain of the file that failed. This eliminate d resending all files but allowed me to send the file that the errors occurred on and the remaining files during the next FTP. The Answer is :
The Compaq FTSO package would be one approach. FTSO provides
automatic restart, retry, command execution upon completion, and
a variety of other useful features.
A sequence of COPY/FTP commands would be another -- see below.
Alternatively, configure NFS serving of the directory involved.
To relocate specified files from one system to another through FTP
or similar file transfer tool via an automated process can be performed
utilizing a three-step procedure:
o The FTP script copies the file to the target host with a
temporary file name.
o It then directs the host to rename the file to the desired
target filename on the remote host.
o When the remote rename has been completed successfully, then
the file on the local system can be renamed to a name
indicating that the file has been transfered.
This sequence prevents the target system from inadvertently
trying to process an incompletely-transfered file.
In the event of a transfer problem, the FTP client will stop executing
the script and control will be returned back to the DCL procedure with
a $STATUS and a $SEVERITY code that can be used for additional error
handling.
