Regarding issue sender file adapter in clustered environment(PI 7.0)

Hi Experts,
we are using sender file adapter in clustered environment(there are 6 J2EE cluster nodes in XI system) for an interface.the file sender communication channel for this interface is scheduled to run twice every day. recently the channel stopped polling (picking the files from the source directory) and i dont see any error.
when i open Communication Channel monitoring in RWB and select the file sender communication channel and run it manually, none of the cluster nodes are polling for the file.
i have tried editing the communication channel in Integration Directory and activating it. but it does not pick the file.
Can you let me know how the issue can be resolved.
Thanks

Kausik,
A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.
clearly your cluster nodes are out of sync...!!!!
It is possible that your ftp server went down for a while . And in the profile of FTP machine the entry of XI server is not made permanent .
1. Try to ping the FTP site from XI server.
BTW are u getting any error msg at RWB ?

Production issue - Sender File adapter not picking up the files from folder

Hi Guys,
Ever since the upgrade from XI 3.0 to PI 7.1, we have come acrossinstances of weird error.
Thsi time again - now the 3rd time - tandom basis, in our production PI server, we have teh file slying in the source directory folder in the server.
I can see the files lying there in AL11.
However, it looks like that the file polling has just stopped and the channel is going blank in channel monitoring.
I have checked in SXMB_MONI and there are no messages since the morning.
I have tried craeting a replica of the current channel but it is not working.
This is teh production server and thsi has alraedy created production issues.
I ahve checked in the SDN forum but am not able to find the details.
Plaese help me.
I am anyway going to raise the issue with SAP now.

Archana

Hi Prateek,
I have trying all sorts since the morning and then just checked teh file permissions.
The file permissions were incorrect as compared ot the other files that were processed successfully today.
Somehow the permissions were changed on the server and the interface channel was not able to poll the files.
I got teh permissions changed back to 666 and all the files were pikced up in a minute.
I got the folder checked and it seems like that the permissions were changed somewhere very early in the morning and we are trying to find out how it happened and who did that.
However, another question i had - this sender file adapter was polling the source directory and deleting the files from there.
I would have expected that if the channel had issues with the file permission because of which it was not able to access the file, it would have thrown an error something like the file permissions error.
But there was not a single error in the channel monitoring.
How can we configure it in a beter way so that we at least soem kind of error indication?
Please advice.

Archana

Duplicate File Handling Issues - Sender File Adapter - SAP PO 7.31 - Single Stack

Hi All,
We have a requirement to avoid processing of duplicate files. Our system is PI 7.31 Enh. Pack 1 SP 23. I tried using the 'Duplicate File Handling' feature in Sender File Adapter but things are not working out as expected. I processed same file again and again and PO is creating successful messages everytime rather than generating alerts/warnings or deactivating the channel.
I went through the link Michal's PI tips: Duplicate handling in file adapter - 7.31 . I have maintained similar setting but unable to get the functionality achieved. Is there anything I am missing or any setting that is required apart from the Duplicate file handling check box and a threshold count??
Any help will be highly appreciated.
Thanks,
Abhishek

Hello Sarvjeet,
I'd to write a UDF in message mapping to identify duplicate files and throw an exception. In my case, I had to compare with the file load directory (source directory) with the archive directory to identify whether the new file is a duplicate or not. I'm not sure if this is the same case with you. See if below helps: (I used parameterized mapping to input the file locations in integration directory rather than hard-coding it in the mapping)
AbstractTrace trace;
    trace = container.getTrace();
    double archiveFileSize = 0;
    double newFileSizeDouble = Double.parseDouble(newFileSize);
    String archiveFile = "";
    String archiveFileTrimmed = "";
    int var2 = 0;
    File directory = new File(directoryName);
    File[] fList = directory.listFiles();
    Arrays.sort(fList, Collections.reverseOrder());
    // Traversing through all the files
    for (File file : fList){
        // If the directory element is a file
        if (file.isFile()){
                        trace.addInfo("Filename: " + file.getName()+ ":: Archive File Time: "+ Long.toString(file.lastModified()));
                        archiveFile = file.getName();
                      archiveFileTrimmed = archiveFile.substring(20);
                      archiveFileSize = file.length();
                        if (archiveFileTrimmed.equals(newFile) && archiveFileSize == newFileSizeDouble ) {
                                var2 = var2 + 1;
                                trace.addInfo("Duplicate File Found."+newFile);
                                if (var2 == 2) {
                                        break;
                        else {
                                continue;
    if (var2 == 2) {
        var2 = 0;
        throw new StreamTransformationException("Duplicate File Found. Processing for the current file is stopped. File: "+newFile+", File Size: "+newFileSize);
return Integer.toString(var2);

I have 4 segments (Header,Detail,Text,Trailer) with "|" as the field separator and HD,DTL,TXT,T are the Keyfields
I need to get the xml structure like below heirarchy. Text segment has to come under Detail structure. Header,Detail and Trailer has to be in the same position.
Recordset
--Header
--Detail
Text
--Trailer
After completion of content conversion, I am getting the XML structure in the below format. All the segments are coming in the same hierarchy.
Recordset
-Header

-Trailer
Text segment has to come under Detail segment. I used the below parameters for FCC.
Recordset Structure: Header,1,Detail,,Text,,Trailer,1

Hi All,
Thank you for your replies.
I thought of doing it in mapping . My map is like
DTL -
> E1EDP01
TXT----
> -
EIEDPT2
According to my scenario when ever DTL comes then E1EDP01 has to come and EIEDPT2 has to repeat untill next DTL comes.
Ex: 1DTL and 4TXT segments .So the output will be..
DTL -> E1EDP01
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
DTL -> E1EDP01
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
Right now I couldn't able to generate the above target XML. Everytime I am getting all the TXT segments under one DTL segment like below.
DTL -> E1EDP01
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -

EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
TXT -
> -
EIEDPT2
Any suggestions how we can get rid of in mapping?
Thanks

Sender File adapter Pooling interval & file Size issue

Hi ALL,
I have a file size of 400 MB to be picked to be the sender file adapter i am facing issue that the system is unable to even pick the file and place in the Q for Processing.
1)we have no mapping no content conversion ....only pick the file from one loaction and place it in 3 different locations with 3 different names ...can any one help me in solving this .. ? the best workable method to achive this .
2) this file is getting created once in a day .say 2 PM .so i can give the poll intravel to 24 hours ..but some times ..the file creation in server gets delayed ..but they cont wain for the next 24 hour to come for processing the file ..so my query is can we reduce the poll intravel for 2 PM till 3PM hour for some 3 times ..and once it reches 3PM it can poll as usual with a gap of 24 hour time ..
thanks
RK

Hi Rupash,
>>I have a file size of 400 MB to be picked to be the sender file adapter i am facing issue that the system is unable to even pick the file and place in the Q for Processing.
Never use File adapter for picking large file (maximum size which I have seen it to work successfully is 200 MB)
Instead go for Java proxies. Check this forum post for the discussion:

Issue with Sender File Adapter

Hi,
In Sender File Adapter I have used content convertion. If the content convetion fails or the channel goes to error state, the sender file channel stops polling. The channel is not polling in the next interval once it goes to error state.
Please help.
Thanks
Aravind

Hi,
That's true.
If one file fails to process due error in content coversion or for any other reason, the channel would stop polling for the next time and also would not process the files following it.
Please correct the content conversion and process the file.

Socket connection time Out - Sender File adapter (Intermittent Issue )

Dear FrIends,
In our sender file adapter i am getting the following issue:
I have already places timout : 120 secs.
This isssue is occuring intermittently.
Error occurred while connecting to the FTP server "100.142.131.30:21": java.net.ConnectException: Socket connection timed out: 100.142.131.30:21

Hi Renu,
You need to increase the timeout Seconds and check.
Run the report RSFTP002.
and check whether the connection to FTP works. Provide the below parameters:
user = <your ftp user>
pwd = <your ftp pwd>
host= <your ftp host/ip>
command1 = <ls>
RFC Dest = SAPFTP
Compress = N
If the issue still exists, then check with your BASIS Team.

Issue while fetching the file through *.extension by FTP sender file adapte

Hello Experts,
I am facing a issue while fetching the data through sender File adapter with ' *.file extension' .I am illustarting the scenario as below .
It is a simple scenarion of File to File inboumd scenarion.Here file is getting picked up from a third party system
through FTP sender chanel and stored in a temp folder of PI through NFS rceiver file adapter .
The problem is however I am getting, while picking the file with file name as "*.exo"(where exo is the file extension).
But while fetching the file with particular name like"abcd_10032011*.exo"(file naming has been done by combination of abcd(always same)_currentdate(change according to current date)),file picked successfully .
So here ,in the prior case file not getting picked up,but in later case it dose .
Can anyone please let me know what might be the issue?

Hi Sunit,
Connect from your PI System to 3rd Party System (where are placed the Source Files)
FTP <PartySystemHostName>
eg. FTP 10.2.3.456 (then insert Username & Password to Login)
Go to source directory
cd \<SourceDirectory>
eg. cd \donaldduck\directory\
Execute a File List command
ls -la *.<extension>
eg. ls -la *.exo
In this way you should be able to view all files with this extension (*.exo), the same action that Sap XI perform to pickup the file.
Then, try to copy that file to your Local PI System (to check if there're some permissions issue):
mget <filename>.exo
eg. mpget File1_01012011.exo

Sender File Adapter always "Polling interval started" without complete

Hi,
I have problem with sender file adapter suddenlty the status from Communication Channel Log monitoring always with polling started without completed.

4/25/11 11:41:40 AM   Processing finished successfully
4/25/11 11:41:40 AM   Processing started
I have tried to stop and start the channel but still no luck. This problem only happen for this particular communication channel others channel is working fine.
Please advise other solution before i need to restart the java engine since this in the production environment. The problem is some of the process was delayed because this issue. CC was delayed to pickup the file.
Thank You in advance.

Hi Abhistek,
Thank you for your correction. It was typo.
Which assumption is correct ?
1. All 3 instance running together in the same time ? or
2. Either 1 of the instance running once time manage by clustering setting.
Example :
15:01:00   ---> A
15:02:00 -
> A
15:03:00 -
> B
15:04:00   -
> B
Currently :
15:01:00   -
> A
15:01:00   -
> B (lock)
15:02:00 -
> A
15:02:00 -
> B (lock)
It seems all 3 instance lose control from clustering ?

File missing from Sender File Adapter

Hi,
I have got some serious issue in the production environment where the file picked up by the J2EE Sender File Adapter has disappeared and I can't see any trace in sxmb_moni, adapter engine monitoring, integration server monitoring within the Message Monitoring.
I have tried increasing the log to 1 in the sxmb_adm-->integration server configuration, still no help.
Can somebody please suggest where should I look at.
TIA.
Ranjan Koirala
The issue was that I was using a separate queue name and somehow the queue was corrupted thats why the message was not going anywhere.

Ranjan,
Incase you are trying to find out what happened to your message, one option could be to use the JMS commands - in particular 'JMS LIST DEADMSGS'. this command i believe lists the destinations for all the dead message on the server.

Archiving TXT files in Sender File Adapter--Unformatted Way

Hello,
I am Archiving TXT files thru Sender file adapter, files are getting archived to specified directory.No issues in that.,
When i open the archived files, those are not in the correct format way that i placed before file pickup.
Header & lines got messed up side by side.
Regards

Hi,
If the file that it being archived is not transformed, it should exactly be the same as the original file.
Please make sure that you are not transforming the archive file by any means(unix script, mapping logics etc).
As suggested above, it is advisable to open the file in the editors like textpad, ultraedit etc. The difference in the alignment could be because of the notepad editor.
Try to open the original and archived files in any of those(textpad,ultraedit etc) editors and check.
Please let us know if you are still able to find the difference in the alignment.

Sender File adapter stops polling

Hi All,
We have a strange issue. A sender File (NFS) communication channel which was working fine, suddenly stops polling.
The cache, is upto date. There are no errors in the channel monitoring. In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the file which is lying in the file location. Channel has been working fine till then.
Finally we had to create a new communication channel with the same configuration which picked up the file instantly.
Is this a known issue with File adapter and is there a solution to prevent this situation from happening.
Regards,
Sathya

In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the
file which is lying in the file location. Channel has been working fine till then
Did you checked if the adapter was locked out? Normally this is the reason....happens with FILE and JDBC....channel shows successfully processed but there is no message that is actually passed.
Needs to unlock the adapter from VA....SAP Note available mentioning this problem.

Abhishek.

Sender File Adapter Ignore Last Line

Hi All,
Like in Sender File Adapter configuration like we have Document Offset to specify the number of starting lines to be ignored,
Like the same way can we ignore the last line of a text file .
Regards,
Rahul

Rahul,
><i>I somehow wait for your answer,</i>
Is that a compliment
I guess there is no standard way to ignore the last line . Like you pointed out, read the line and ignore it in the mapping!
><i>btw ..
suppose in a flat file..
i just want to read the 4th line??
is there any way i can do this?</i>
Again no straight forward way to do this. You can use KeyFields etc , but there is no direct way to do this and every solution would depend on the exact requirements!

Sender File adapter not picking the file ABCD.PRN extension file

Hi
Am doing File to Abap Proxy scenario. My source will be in text format of fixed length of fileds 7.
My souce file will be generated by a third party machine with the extension EEE150809.PRN. In my scenario my file adapter should pick the file and update the same in ECC via a Proxy.
I have configured the Sender File adapter with Message Protocol - Content Conversion but file adapter is not picking the file. I have checked the Communication channel and status is fine. But the same Communication Channel works for .XML file.
What are the parameters that I have to consider with the file extension .PRN using File adapter?
Thanks.
S.

Hi Swarna,
You dont need to worry about the extension when picking the file. You can try using EEE* so that is picks all the files starting with EEE. If you have the fixed name then you can try giving EEE150809.*. Also EEE150809.PRN should not have any issue. Try to see in sender commu ication cahnnel for anyerrors. Probably there might be some network issues or authorisation issues. If you are reading with NFS then ask them to give necessary permissions. If you are reading through FTP check the user id and pwd you are using.

How to count the number of files read through sender file adapter

Hi ,
I have a scenario where I am reading files from a third party system and trying to send those files to R/3 system .The frequency is 1 file per day .But there can be situation where the source system can put 2 to 3 files in source folder and so XI sender adapter will pick up all the 3 files at time . And I want to send only 1 file at a time to r/3 .
Do you know any way to handle this requirement ?
Thanks ,
Suvarna

Hi,
Like Bhavesh pointed out, you could EOIO as the Quality of Servie in the sender file adapter.
But I guess this would solve your issue only to a certain extent.
Marking this QOS in the sender file adapter would only mean sequential processing of the files. That is, the second file will be sent only when the first file is successfully received by the end system.
It would not ensure that the files are sent only after 15 mins of the first file is sent.
If the 15 mins time period is important, then this needs to be achieved using a BPM which ensures that the messages are sent to the target only every 15 mins.
In case, the frequency of the incoming files is not known (in which case, the having a BPM would be a bad idea) you could use a ztable, which stores the filename and time the file was sent to the R/3.
You could query this table each time, before sending the file data to the R/3

Smitha.
