  • FTP Question

    Merry Christmas everyone!

    I have an FTP situation I've not run into before and cannot find anything on this anywhere.

    I need to pick up multiple files from a remote server (not an i).
    I do not know the file names and the names will never be the same name.
    I'd like all the data from all the files to go into 1 i file.
    The data format will always be the same for every file.

    I'm hoping someone can help with these questions;

    1. Is the proper format of the FTP command 'GET * QTEMP/MYFILE (REPLACE'

    2. Will all the data from all the files received be put into qtemp/myfile?

    Thanks all,
    Gary

    Re: FTP Question

    Hi Gary,

    Unless I'm much mistaken, you cannot use a wildcard on the GET subcommand. If you could, however, the way you've coded it would not work as desired -- it'd replace QTEMP/MYFILE for each file downloaded, the effect of which would be that only the last file would be in QTEMP/MYFILE (since it would've replaced the prior one.)

    May I suggest a different strategy?
    • Create a temporary directory in the IFS. If you're able to write a program, the IBM-supplied tmpnam() API can create a unique name that's unique.
    • Build an FTP script (on-the-fly) that uses the MGET FTP subcommand to download all files (using a wildcard) to the temporary IFS directory.
    • After FTP is successful, combine the files in the IFS directory (QShell could do this easily) into a PF in your desired library.
    • Delete the temporary IFS directory, and it's contents.


    I'd be happy to provide further details on any of these steps, if needed.

      Scott,
      I was afraid this might be the case.
      I'll probably be back for more information after I've had time to work on this approach.
      Thanks so much for the input.
      Gary

        I use this to list files on a server and copies them to IFS on IBMi
        be careful when testing it deletes the server copy!

            Re: FTP Question

            Jamie,

            I use SQL quite a bit, mostly for fetching, and am not much of an expert.
            Why would I be getting the error below when I try to INSERT into INPUT.

            Thanks,
            Gary

            Member INPUT not journaled to journal *N.
            INPUT in QTEMP not valid for operation.

                cool....
                did you do this as first executable line of code?
                PHP Code:
                exec sql  set option commit=*none,datfmt=*iso

                  Re: FTP Question

                  Yes I did. I searched out the answer, which I should have done before I posted.

                  I've been down this path before but I do this so infrequently that I had forgot this step.

                    Hi guys,

                    I continue to have problems trying to pick up files from a server.

                    Below is the session and the name of the file I am getting seems to be a problem.

                    Thanks again for any assistance you can lend.

                      Re: FTP Question

                      You are telling it FTP to create a file with a member named "0bte0l007dmdqvg80000qvp1_39", but a member name can only be 10 characters long.
