None of the file Sender Communication Channels are wotking in Prod-Urgent

facing a wierd situation, since yesterday all of my File Sender Comm Channels have stopped picking up files.This is in Production and was working fine day before.When I check in Comm channel monitoring the Channels are started and Functioning and also shows me that they are polling for the files.But no file is picked though files exist in the directory.These channels have been working fine since months and nothing had been changed since then.Suddenly all of them stopped picking up files.
I have about 10 Comm Channels that pick files, Is this related to Adapter Engine....any suggestions on this would be really apprecated.
Thank You.

Hi!
Check access rights on your files. Try to set them to 777 (using chmod). Maybe this will help.
Problem is, when the XI does not have rights for picking up files, you see no errror message in CC monitoring and everything seems to be ok, but it is not..
We faced the same problem.. And we figured out, that our partner started to upload files with different access rights.

  • File sender Communication Channel is not working

    Hi friends
    we  Created File sender Communication Channel and Activated but It is not picking up file
    1.  0 messages in Message Monitoring
    2. My Communication Channel not appearing in Communication Channel Monitoring also
    3. We have refreshed the cache and activated the channel.
    we chack with File name, Directory name and  path ....
    Friends have any idea
    Regards

    Perosnally, I would recommend setting a trace and letting the system telling you exactly why.
    Traces are used to analyze runtime errors.  By setting a specific trace level for specific locations, you can analyze the behavior of individual code segments at class and method level.  This is done with the help of the log configurator service:
    Log onto the Java Admin Console
         Services
         Log Configurator
         Locations
         Choose the location (Java package) and the tracing level (severity)
    (for example, com.sap.aii.adapter.file)
         Root Location > com > sap > aii > File
         Set the severity and choose Copy Severity to Subtree

  • File sender communication channel stop working

    Hi Guru,
    I have a file sender communication channel. It usually works good. But sometimes it just stop working. And In RWB, it shows no error. If I stop it and restart it in RWB, it immediately works again. This happens once a while. Any ideas?
    Thanks,
    Meiying

    Hi,
    option 1--
    Do some dummy changes and activate channel and try and perform cache refresh.
    If still not working then  stop and restart SFTP service,if still no luck then restart JAVA stack
    option 2
    try to put timeout value in the channel.
    Regards.

  • FILE SENDER COMMUNICATION CHANNEL DOESN'T GET FILE

    Hi,
    I have create a new sender communication channel with ftp file configuration. Server parameter and source directory are correct.
    I have also checked file and directory permission (chmod 777)
    Poll interval is 600 secs.
    There is no error in communication channel monitor  (returned log: CC is correctly configured and started).
    Process started every poll interval, but no file is picked up.
    Why?
    Carme

    Hi,
    What type of file are you processing. Check whether the file type is binary or text mode.
    Also check whether the file name you have specified in the CC and the exact file in the directory are the same.
    Also check the file processing mode, whether it is read only, delete or in test mode.
    If the file is in read only mode when the file first processed, then once the file was processed it would be in read only mode, so if you place the new file it should process, so try deleting the existing file in the directory and place a new file with exact file name along with the correct extension and try to process it.
    Also I would suggest you check the exact file extension, by unchecking the radio button in the folder option under the menu tools> Folder options> view-->hide extension for file type.

  • Problem in File Sender Communication channel

    Dear all,
    We have FIle TO RFC scenario, which have been running in Production since long time.
    Problem :  Many of the time we have obsereved that even if the FTP is up and running , but file is not getting picked from ftp server. File name and all other details are maintained correctly. Can you please suugest me to resolve this issue.
    Regards,
    Raghvendra

    First of all: the connect parameter should be set to 'Per Transfer': this ensures that a new connection to the FTP server is established for each file transfer. That means that you don't loose connection to the FTP server in case of a hick-up.
    Second: are there any errors in your communication channel monitoring?

  • File Sender Communication Channel not working

    Hi All,
    We have one file sender channel which sends file after every 3 hours.
    But currently it has stopped the processing of file.
    If we see in RWB it shows that "Correctly configured and started",but if we start and stop the chanel it doesnt show any processing started message.
    File is there in the folder but the channel doesnt poll the folder to pick up the file.
    We have refreshed the cache and activated the channel again.
    But still no luck,does anybody have any idea?

    Hi Shweta,
    Please check the parameters of your File adapter. There can be following  possibility if File adapter is not picking the file :
    1. File adapter is not active
    2. Incorrect File name, Directory name or path,
    3. File does not exist in the source directory.
    4. If you are accessing file from other server (use FTP protocol) check you have READ and WRITE access.
    Thanks
    Farooq.

  • Update query not working in the JDBC sender Communication channel

    Hi,
    We are working on JDBC to File scenario. As per the configuration, XI should pick the data from SQL database every 20 secs and should update the corresponding flag. We are using subquery in the select and update statement as both header and detail tables are involved.
    Now the issue is, select query is working fine but update statement is not working as expected. It is somehow updating some other records rather than doing for the ones selected by the adapter.
    Moreover logSQLstatement is also not working. Hence we are unable to identify the records which are getting updated.
    Please advise.

    Hi Rumi,
    See Question 8. Transaction Handling (Sender) in [SAP Note 831162 - FAQ: XI 3.0 / PI 7.0 / PI 7.1 JDBC Adapter|https://websmp130.sap-ag.de/sap(bD1wdCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=831162].
    8.  Transaction Handling (Sender)
    Q: If I have the following configured in a JDBC Sender:
    Select Query:
    SELECT column FROM TABLENAME WHERE FLAG = "TRUE"
    Update Query:
    UPDATE TABLENAME SET FLAG = "FALSE" WHERE FLAG = "TRUE"
    How do I know that the JDBC adapter will not update newly added rows (rows that were
    added between the time that the SELECT and UPDATE queries were executed) that were
    not read in the initial SELECT query?
    A: The SELECT and the UPDATE are run in the same DB transaction, i.e. both statements
    have the same view on the database.
    Make sure that both statements use the same WHERE clause. An additional
    requirement for the correct operation of this scenario is the configuration of
    an appropriate transaction isolation level on the database
    (i.e., repeatable_read or serializable). You might also consider using a
    "SELECT FOR UPDATE" statement instead of a plain SELECT statement to
    ensure proper locking on the database. "SELECT FOR UPDATE"
    is not supported in MS SQL database. In this case please make use of an
    appropriate transaction isolation level on the database. For more details
    please contact your DB vendors.
    After, see Transaction Handling Issues in [SAP Note 1039779 - JDBC Adapter issues(Escape character,Transaction handling)|https://websmp130.sap-ag.de/sap(bD1wdCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1039779].

  • Why my FIle sender Communication channel is inactive?

    I tried to edit and save it again, but i can see active at ID but inactive at RWB-->Channelmonitorring..
    what to do?

    May be in the channel monitoring the channel is stopped. If you are sure that the channel is active in ID and in Start mode in communication channel, then it is a cache issue. Then, perform full CPACache refresh.

  • Restrict E-mail sender in the Mail sender communication channel.

    Hi All,
            My scenerio customers want to Email with attachment to PI server. I've successfull tested this scenerio without one open issue. Right now anyone having email id can send mail to PI server.
    I want to restrict the senders list. Is this possible in the sender Mail adapter configuration.
    Thanks,

    Hi,
    Its possible.
    You need to configure 2 receiver
    1)MailA
    2)MAILB
    in receiver determination.
    then you need to route it based on Subject using condition in receiver determination.
    Use the below XSD to create your sender mail message type
    <?xml version="1.0" encoding="utf-8" ?>

    and use mail package in sender mail adapter.
    Then your mail will come in XI in the above format.
    then based on subject field you can conditionaly determine the receiver.
    Message Protocol
    u25CF      XIALL
    In this mode, the content of the RF C822 e-mail matches the content of the XI message. The XI message is a multipart MIME message with a SOAP envelope as its first part. See also: Messages, under XI Message Protocol.
    u25CF      XIPAYLOAD
    In this mode, the content of the e-mail is put in the payload of the XI message. If you do not set the Use Mail Package indicator, the information about the sender (From), receiver (To), and subject of the e-mail is lost.

  • Testing the File sender from local computer

    Hi Gurus,
    I know that this is a very low level question. I am working on a File-XI-IDOC interface. I wanted to keep the file on my computer. How to set the file adapter sender which can pick up the file from my machine.
    I have downloaded WS-FTP Server on my machine and given my computer's IP address in the file sender communication channel. Where to keep the file so that XI can pick it up?
    Please help.

  • XI-Multiple instance scenario -File & SQL sender communication channels

    Hi
       i have a basic question regarding how file sender communication channel ( where we poll for a particular file pattern either using file/ftp types in a particular subfolder ) or a sql sender communication channel - ( selecting records from a sql source ) would work in a scenario with two active XI instances and j2EE file and sql adapter services running on both of the J2EE servers ?
    1. How would the file polling from both J2EE servers - avoid a conflict looking for the same file pattern ? Is there any inbuilt mechanism from SAP to make multiple instances work with the file polling - without a confict ?
    2. Simlar question for SQL sender type communication channel ?
    If SAP does have a mechanism to handle multiple instance scenarios for file and sql sender adapter based communication channels, is there a link/document on this ?

    Hi Karthik,
    Please see my comments.
    I am just wondering aloud - what will happen if we use a select for update clause in the sql sender adapter communication channel -
    Gouri: Yes you can use select + update. In fact that is the right way.
    will this ensure that polling from one J2EE instance will lock the selected records so that the second instance does not select the same set of records from the sql server ? Or should we not use a select for update and use a simple select statement ?
    Gouri: Yes. SQL DB will ensure that same data will not be picked by another node. As I mentioned earlier use serilizable option from advanced mode.

  • JMS sender communication channel content conversion

    Hi,
    I struck with the content conversion in the JMS Sender communication channel.
    I have configured the communication channel with the filed fixed lengths. (Simple type)
    The field fixed lengths i have given are 10,2,3,11
    The contents in the file 1000000072  230 111
    but, in the input xml after conversion iam getting 100000007 in the first field and 2 in the second field 23 in the third field.
    I have configured the sender communication channel as in the document in SDN.
    Even, i configured several communication channels. I didn't get this strange error any time.
    I have gone through SDN to fix this issue, but i didn't get solution.
    If anyone got rectified this kind of error, please answer your solution to me
    Thanking you,
    Regards,
    Krishnaraju.

    Hi,
    Thanks for all your support. The issue got resolved.
    The issue is due to the file, In the file the special characters are appearing. We are not able to see these characters in the notepad, wordpad, text editor.
    But, these characters are appearing in th syn text editor. So, we removed those characters and processessed the file. Now, it is successfull.
