Partial File picked up by XI

Hi,
In one of our Production Interface run we found that XI FTP Adapter Comm Channel was picking up files before they were completely written to by another legacy application.
We thought that because of the process lock by the writing application XI would not be able to poll/get the file and would only poll/get the file once it was completely written by the writing application. But we were proven wrong.
Is there any setting in the Comm chnnale that checks for process locks at file level or anything which can prevent XI application from picking up incomplete/partial files. For the moment increasing the polling interval has helped us in fixing the issue but we wanted to know if there is any cleaner solution for this.

Arunava

Hi,
have a look at this thread to give you more ideas on its control.
File got picked up too soon
check on this File adapter proprty:
Advanced Mode
To specify additional parameters in the adapter configuration, set the Advanced Mode indicator.
Msecs to Wait Before Modification Check
Enter the number of milliseconds that the adapter must wait before it checks whether the files have been changed.
This parameter is not available if you have selected File Content Conversion as the Message Protocol and then made an entry under Recordsets per Message that splits an input file into several messages.

  • File adapter picking up partial files

    Hi All,
    We are facing a wierd problem with the File Adapter.
    The problem is that, we are getting the xml files from the source system, and PI is supposed to pick them up and process them. Sometimes, the file adapter is picking up the empty files / partial files, i.e., before the file is completely written on to the FTP folder.
    We tried increasing the polling interval. But this did not help. Since we are taking the files from the FTP, the option "MSecs" in Additional Parameters also will not work. As we are on PI 7.0 SP13, we tried to search for the "Empty File Handling" option wherein we can make the file adapter skip the 0kb files. But we are not able to find that option anywhere.
    Please help us find a solution to this problem.
    Thanks,
    Hari.

    Hari,
    In sender communication channel click on  Advanced. Then you see the paramter Msecs to Wait Before Modification Check. Add a value 3000. Then you should be good.

  • How to avoid partial files via FTP from XI to an external server?

    Hi all,
    I'm working in an interface where XI sends a big file (greater than 1MB) via FTP to the client. The client needs an empty file to be created once the file has been fully sent from XI, with format <b>.ok</b>, so that their server can trigger their interface to process the file.
    They want this procedure to ensure no partial files are processed.
    Could someone please help me out on how to do this in XI.
    Thank you.

    HI rajendra
    look into this
    file.checkFileModificationInterval=<msecs>
    Use this parameter to define a length of time (default value: 0) for the file/FTP adapter to wait after the file has been read to see if the file length changes. If this is the case, the system repeats the read procedure. This is useful if the files to be imported by the adapter are generated dynamically without being locked on the operating system level (for example, files received from FTP servers). Without this workaround, the file/FTP adapter cannot recognize whether the generation of the file is complete in such applications with operating system functions.

  • File Pick up issue in PI 7.1

    Hi Everybody,
    I tried a File scenario , while configuring the communication channel i didnt know the exact path to provide, because if i use FTP error occurs and with local drive I'm getting error as unidentified.
    Please suggest me as what are the settings and authorization needed for setting up file pick up.
    Thanks

    Please go through the link below:
    http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
    It gives the details of the sender file adapter configuration.
    Source Directory
    Specify the directory where the files to be processed are located.
    You can either specify the entire path name or a name relative to the working directory of the Adapter Engine. In all platforms (including Windows), use a forward slash (/) to separate directory names in accordance with Java specification.
    File Name
    Specify the name of the file that you want to process. The name can contain placeholders (*, ? (placeholders for exactly one character)) so that you can select a list of files for processing.
    ALSO TAKE CARE OF THE FACT THAT THE SOURCE FILE AS WELL AS THE DIRECTORY WHERE THE FILE IS PLACED,BOTH SHOULD HAVE "WRITE" PERMISSION "ON".

  • Lock Finder view as list in every Window/File picker

    I have my Finder in list view: always and everywhere (except for the occasional pictures folder).
    Within Yosemite I encounter a lot of differences. Sometimes a folder opens in icon view. When the file picker windows appear (in Pages for example) it is icons or columns. It changes randomly.
    Is there a way to lock every view of files to "list view".
    I tried in Finder, View Options, set as Default. That doesn't work.

    Thx for that im gonna try it....but is there a way to do it without using toolbar or cmd-c...? i mean using only the mouse?why does it have to highlight the file even though i click a bit next to it....?using icon view i can right click next to the folder and i wont have a problem but with list view that i prefer using it will highlight the whole row.....and i dont find free space to right click cause i got many files

  • Empty file picked although file have lot of data in file adapter SAP PI

    Hello All,
    We are facing the weired behaviour of SAP PI file adapter channel.
    In without mapping Scenario of 7.31
    At some time whole file is archived properly in archive folder but in SAP PI log we can see the file size 0 bytes.
    And at received side empty file will be sent.
    But in actual there is lot of data in the file.
    The same file triggered next time then it working fine.archived and sent as it is.
    So can anybody help me for this ?what is the issue why sometime file with no data is  picked by PI?
    If file is pick up by PI before it is written completely by third party then is it possible that archived file will have all data as it although processed empty ?
    Thanks in advance,
    Anant

    Hi,
    Thanks for reply.
    I know this is common issue of file picking before completing the process of file writting and also i can use Msec to wait before modification check for avoiding this but
    my question is how the archived folder have the file with all data that sender is sending.
    So is it possible that empty file (before compete writting )is picked up by sap pi and then after completing the picking process it will archive the file that is completely written by third party in source folder.
    In other way file picking & File archiving is separate process means file that is picked is not archived but once pi processed the file then it will again check the source folder and archive and delete the same file.
    Thanks

  • How to increase the files picked up by File Adaptor per poll interval

    Hi,
    We have a scenario where in we post 80 files in the source directory and and the file adapter is configured for every 300 sec but i have noticed that the File adaptor is picking up one or two files per poll interval.Can some please suggest how to increase the number of files picked up by File adaptor
    Thank You,
    Nandini

    Nandini:
    Did you mention all the files names in the Adapter channel. One thing you can do is use wild cards and file adapter picks most of them
    /people/mickael.huchet/blog/2006/09/18/xipi-how-to-exclude-files-in-a-sender-file-adapter
    In case if your files are huge, then I guess file size may cause to process few files during each poll

  • Number of files picked up by file adapter

    Hi
       I have a scenario in which - I have a large number of files at the same time - to be picked up by the file adapter - each file is very small in size - like a token file a few k in size.
    If I have - say 1000 files present in the folder meeting the criteria to be picked up , will the comm.channel pick up all of the 1000 - or is there a limit - on the number of files picked up in each polling  ? Where is this limit set - in the comm. channel definition or somewhere on the J2EE engine at a much higher level ?
    Any correct answers will be instantly rewarded.

  • How to increase the number of files picked up by File adaptor

    Dear all,
    Can any one tell me how to increase the number of files picked up by File adapter.
    Pl post ASAP.
    Useful answers will be appreciated accordingly.
    Thanks,
    Srinivas

    Hi Srinivasa,
    there is no parameter for number of files to be picked..............if you have too many source files and you want to get them processed quickly, then you can specify a very small polling interval, then XI will pick your source files quickly..........but it will cause heavy load on the XI system which can lead to blockage of messages in queues........

  • What are *.partial files

    Hello,
    When getting existing projects into my local workspace from VS2013, it also retrieves some .partial files, all void (0 bytes), and in the 'pending changes' window of Team Explorer, they are suggested in the "promote candidate changes" window, all
    of them as 'add' change:
    What's more weird, if I delete the obtained project from my workspace and then re-obtain it a 2nd time, then I'm getting a different number of .partial files, and the third time I tested it (for the time being), finally NO partial file appeared. Could it
    be a bug ?
    Windows shows the extension type as a 'partial download'. I don't know why I'm getting these files, nor if they are necessary to include.
    Thanks in advance,
    Roger

    Hi Roger,
    Since you saw "promote candidate changes" window, so the files might added to the local path of your workspace but not added into source control. And you can click add them to source control or just delete the files if
    you don't need to them. You can also change the local path of your workspace, then you will not see the files
    Another option is create a new workspace and use a different local path, then do a workspace mapping. Thanks for your understanging.

  • Why does file picker unexpectadly closed by Windows message keep hanging Firefox 4 when trying to browse destination folder for download?

    Whenever I try to download a file, Firefox 4 asks me to choose a destination folder, then when I browse and choose the folder for the download, Firefox just hangs, and I get the file picker unexpectedly closed by Windows message. I end up having to use task manager to close Firefox.

    The post I was responding to said,
    "Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps. "
    Somehow, I think that means Windows...
    I've tried Firefox in Safe Mode - it makes no difference.

  • KM file picker for new WPC editors

    Hi there,
    I'm using new WPC editors and I want to insert some picture from KM into paragraph. However, the displayed popup only allows that users input the full URL.

    Is there something similar for new editors?

  • OpenOffice w/ KDE file picker dialogs

    I have OpenOffice 2.3 installed with KDE, and "export OOO_FORCE_DESKTOP=kde" (in /etc/profile), but I am still getting the yucky openoffice default dialogs for file save/open.
    The KDE file picker rocks - since you can access any konqueror bookmark, including sftp://, etc.
    Do I have to rebuild OO to get this?  If so, what build flag drives this?

  • Queue Blocking and File picked Partially Problem ?

    Hi All,
    The File which is placed in FTP server having more 50000 to 65000 rows .
    when XI picks the File the Partial Data is processed.
    In SXMB_MONI if we check the message we are able to see some rows not full Data which was in file.
    it's also blocking the Large message QUEUE -XBTM0000
    while processing.
    In QUEUE monitoring(SMQ2)  the STATUS message is "Connnection CLosed No DATA" .
    what could the reason here and also we are not able see any error related information(If it is having error) in SXMB_MONI.
    it's urgent because of Production issue.
