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

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.

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 ?

Sender file adapter not polling the file

hi all,
i have configured a filexifile scenario....
but the file sender adapter is not polling the file at all....
i dont c any message either in RWB or in SXMB_MONI
i checked the adapter framework url at http://<ximachine>;<port>/AdapterFramework....and the status for the file adapter is green...
but the message it gives there is
Sender Adapter v1014 for Party '', Service 'TASL_FILE_SENDER':
Configured at 03:07:24 2006-02-02
Up and running - no message processing until now
last poll interval started 04:01:24 2006-02-02
length 60,000 secs
y is the sender adapter not polling the file..
i am using NFS as my File System....i gave the source directory as d:/test_dir/
is this way of specifying the source directory on a windows machine correct...
thanks
pavan

There is probably something wrong with the File Adapter. You will need to go to the RunTime Workbench >> Component Monitoring >> Display >> Click on the Adapter Engine >> More information will display and click on the button 'Adapter Monitoring' >> A new window will display and click on the arrow next to your adapter engine. This displays a list of adapters running on your system. Green light means good; Red, you have a configuration problem. Look at the error and try and resolve it.

Sender File Adapter stop processing all files

Hello all,
the file adapter pick up all files in the directory by default.
if a large number of files are in the directory then this could slow down the pi processing.
is there any way to process only one file per polling??
regards

I do not have any proble if you have got the answer. BUT this blog says how to exclude the other files from the same folder.
Your Case: For example, Your Sender CC wants to pick up file ABC.txt from /xyz dir, now suppose there are 10 thousand files of same name in the dir and you want ABC.txt should be picked up one by one, So how this blog is going to help you. Can you Plz explain to me and others too?
@Sachin may be you can throw some light on this... may be I am missing something.

FTP File adapter stops polling

We r using SAP PI 7.0
In File FTP adapter we had set 120 sec polling interval and timeout parameter 120 sec
I have seen 1083488 sap notes even , it shows this patch..
PI 7.0 SP12 ADAPTER FRAMEWORK CORE 7.0
Support Package 12, Patch Level 3 (SAPXIAFC12P_3.SCA)
Can anyone tell more about this error resolution...

Check whether the Adapter Engine is working fine(In RWB). check your coummunication channel in RWB channel monitoring
May be your channel is locked. See this 1083488

PI 7.1 File & JMS Adapter stops polling at random times

Hi All,
IN PI 7.1, at random times, the File Adapter stops polling. But status is green in RWB.
It starts working after the restart of File Service.
Any idea why this happens? (We don't use FTP Protocol)

Yes Ravi. We recently migrated to PI 7.1 from PI 7.0.
We dont use AAE.
We are on Support Pack 7.
"Adapter Framework is changed in handling threads on the backend in SAP PI 7.1"
what impact it might have on the File Polling?

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.
Regards,
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

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.

Read uniquely named file. Sender File Adapter unsuitable for synchronous

Hi All,
We have a requirement to read a specific file that has a unique name based on a transaction ID. The transaction ID will be passed from the source application.
The communication is required to be synchronous. There could be multiple requests/files generated and present at the directory at any given time but each corresponding to a specific transaction ID. If the file is not yet generated for that transaction ID we return back an error to the calling system.
I think we can not use Sender File Adapter - because of the dynamic naming and also because we have to return a synchronous response back depending on the file availability. i.e. We can not have a defined pattern in the file name nor can we specify a wild card as there could be more than one files in the location.
In theory we could use the File Sender adapter to read all the files in the directory and a BPM with correlation set based on the transaction ID and let the process wait for the request. But as far as possible I want to avoid this unnecessary wait or extra demand on the system. More so because the files could get big.
If I were using a tool like SAP Business Connector or webMethods then I would I used a readFile Java service and given it a filename to return the required bytes in a synchronous read.
Is something like this possible in XI? If someone has written a synchronous Java to read file can they share the code? Or do you suggest I write a ABAP server proxy to read the file? The problem however will be how do we map the data to a XML within the code.
All suggestions welcome. There has to be a simple and effective solution to this mundane requirement !
Wishing all SDNers a bright start to this new year,
Thanks,
Charu

"The transaction ID will be passed from the source application so we know what file to pick"

Hi,
You could make the scenario a little simple and avoid custom development if the logic can be put into scripts(out of XI).
Say all the files are coming into a directory called D1.
Here, you could use a script to arrange all these in an order (say ascending) and move the first file into another directory D2.
The sender file adapter would poll this directory D2. The adapter can have a wild card character for the filename field now.
Once the file is in XI, you could check this against the transactionId present(I am not sure how you get this though!), and determine whether to send a mail, or to send a file back.
Here, I have assumed that there is somekind of order present in the files placed in the directory D1.
Again, this is just a suggestion.. I might be wrong with all the assumptions.

Smitha.

Selective Polling in the Sender File Adapter

Hi,
I have the following requirement
1) File X is placed in the directory which is the source file for the sender adapter to poll
2) File X is appended regulary with data until it is polled. During this appending the sender adapter should not poll this file
3) Current process (without PI) they use a control file to stop this happening. i.e. they place a File Y in the directory to show the file is being updated and not to be touched. Once The file is appended File Y is removed and the file should be polled
So ultimately I have to configure the sender adapter to poll for File X (say every minute) except when there is File Y in the directory.
Any ideas?

Hello,
You can use the "Msec to wait before modification check" feature in sender file adapter to achieve the requirement.
No need to place the "File Y"...i.e step 3 to perform.
Check the below link for more details:

Sender File Adapter - Restrict number of file polled at each poll interval

Hi all,
PI 7.0 SPS16.
We would like to know whether it is possible to configure a sender file adapter (file conversion mode) in order to restrain the number of file taken at each poll interval and if yes how ?
Thanks for your future answers.
Jean-Charles

Hi Jean
Standard adapter do not provide functionality to take an input like number of files to be taken at poll interval. But using adapter module you can achieve this.
SAP PI is having the function to set poll timings and scheduling. You can write adapter module and execute this module using File adapter type communication channel before the standard bean and you can restrict the number of files.
Check the link given above as well as this How to Guide
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/3bdc14e1-0901-0010-b5a9-a01e29d75a6a

Sender file adapter is not polling the file.

Dear all,
Sender file adapter is not polling the file.(But Receiver file adapter is getting the file)
we have installed SP15.
It was worked fine for previous SP14.
I have cheked in Adapter monioring also.
Can you help me out of this problem
Regards
Dhanabal

Hi Dhanabal,
Is the XI system running on a unix machine ?
If yes, from the OS level for the folder you are using in the file comm. channel, execute the command
chmod 777 <folder_name>
The reason for the file to show up in receiver side and not get deleted might be that the xi user mighht be having only read access to the folder...
Thanks,
Renjith.

Poll interval for sender file adapter.

I have a 1_sender file NFS file adapter which picks a trigger file from X location in PI application server, this trigger file initiates the unix script present in the sender file adapter.
Unix script brings all the file which starts with 25588* from bank FTP and places in Y location in PI application server then script deletes the "trigger file".
another NFS File adapter 1_receiver file adapter places the trigger file in the X location of PI.
for 1_sender file poll interval given as 86400, that means it should trigger only once a day @ 1:30pm.
But today same sender file adapter had triggered 4 times, could any one let me know the reason why it had triggered 4 times instead of single time.

Vidya,
There are two things :-
1. The polling interval should be 24 hrs;
2. The polling interval should be 24 hrs and it should poll at 1:30 pm every day.
For any reason if the channel is re-started, then with your present configuration, you will never be able to achieve # 2.
So, better use ATP.
But today same sender file adapter had triggered 4 times, could any one let me know the reason why it had triggered 4 times instead of single time.
Might be the connection dropped / failed at the time of polling and the channel re-tried. If you give more details (what time and with how much interval it triggered), someone might be able to help.

Neetesh

Sender File adapter and duplicate file processing

If I set the sender file adapter to delete or archive and when a file gets picked up and processed, this file will not get deleted/archived unless it was successfully processed. However, if it errors out during processing, the file remains but it's message will get persisted in the integration engine or adapter engine. Since there's automatic retry, we have the potential for duplicate processing as in addition to the retry, the file is still continously polling for this file. In other words, how do we stop this duplicate file processing?
Thanks.

Hi Bevan,
However, if it errors out during processing, the file remains but it's message will get persisted in the integration engine or adapter engine.
your file wont get deleted unless adapter engine sucesfull pickups. if does not picked up at adapter engine then is not stored in adapter engine . if it reached Intergation Server and failed their then file would be deleted.
please let me know if you haveany questions
please reward points

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 ?
