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 11:40:33 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:23 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:13 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:03 AM   Polling interval started. Length: 10.0 seconds
Normal :
4/25/11 11:41:50 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:41:50 AM   Processing finished successfully
4/25/11 11:41:50 AM   Processing started
4/25/11 11:41:40 AM   Polling interval started. Length: 10.0 seconds
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 ?

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 <i>http://<ximachine>;<port>/AdapterFramework</i>....and the status for the file adapter is green...
but the message it gives there is
<i>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</i>
y is the sender adapter not polling the file..
i am using NFS as my File System....i gave the source directory as <i>d:/test_dir/</i>
is this way of specifying the source directory on a windows machine correct...
thanks

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.

Is Sender File Adapter always throws error when there is no file?

Hi,
I have a simple question but can't find a straight answer to it. I have a Sender File adapter that configured to pick up file XXX* from FTP server every 1 hour. But a file can come every 2, 3, or 7 hours- no certain time.When there is no file I got "File not found " error. As we use alerts, this behaviour is not acceptable.
Does this error comes always if there is no file? Any possible way to avoid this error ?
Thanks for help.
Nataliya

Hi Ravi,
I can see the error in Runtime Workbench under CC monitoring. To be precise it says:
An error occurred while connecting to the FTP server '1X.1XX.XX.XX:21'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 552 RMS-E-FNF, file not found, ES4_SAP*'. For details, contact your FTP server vendor.
My ftp server has the following set up:
Server: xx.xxx.xx.xx
Port:21
Dataconnection:Active
Timeout:120
Connection secuirity: None
User name .... etc set up.
Connect mode: Per file transfer
Transfer mode:Text
QoS:EO
Pollinterval: 120 (for test purposes)
Processing Mode: delete
Can it be that its a ftp server generates error and sends back to XI?
Thanks,
Nataliya

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.

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.

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

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 - 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

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.

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:
Java proxy to use XI as a file mover

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
<b>chmod 777 <folder_name></b>
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.

Sender file adapter error

Hi,
The sender file adapter is reading a fixed width file . The file is not to be seen in the sxmb_moni. In the adapter monitoring is showing processed and green in color.
How do i resolve this issue.
In my recordset contains multiple substructures
<Recordset>
        <Header>
             type
             code
             id
        </Header>
        <Item>
                    type
                    qty
                    price
        </Item>
</Recordset>
Header.fieldFixedLengths = 1,5,10
Header.endSeparator = 'nl'
Header.fieldNames = TYPE,CODE,ID
Header.keyFieldValue = 01
Item.fieldFixedLengths = 4,5
Item.endSeparator = 'nl'
Item.fieldNames = QTY,PRICE
Item.keyFieldValue = 02
What should i give in keyFieldValue . Is the above configuration correct.
Kindly suggest
Thanks
Varghese

Hi,
The key field value is normally a record type identifier. For example, a header record may always start with '1' or 'HD', and an item record may always start with '2' or 'IT' in your file. The 'type' field, which appears in both header and item records in your example, fits in as the identifier.
So, your parameters should be:
Header.fieldFixedLengths = 1,5,10 (or maybe 2,5,10)
Header.endSeparator = 'nl'
Header.fieldNames = TYPE,CODE,ID
Header.keyFieldValue = 1 (or maybe HD)
Item.fieldFixedLengths = 1,4,5 (or maybe 2,4,5)
Item.endSeparator = 'nl'
Item.fieldNames = TYPE,QTY,PRICE
Item.keyFieldValue = 2 (or maybe IT)
If your file has varying values of TYPE instead of 1,2 (or HD or IT), the File Adapter will not be able to handle the structured file. You may have to choose the option 'File without content conversion'.
Hope this helps,
Bhanu

Sender File Adapter is not reading anything

Hi,
I have a really strange problem here. I'm tyring to read a file using file adapter (FTP) and the adapter doesn't read anything and it does not throw any error in the communication channel monitoring.
I'm using a receiver file adapter to write files to the same FTP folder, so it can't be a connectivity problem. And I tried to get the file using Filezilla and it works fine...
In the sender file adapter I tried to simplify the maximum to solve the problem:
- NO File Content Conversion
- NO advanced attributes
- I used the "*" in the file name to read any file
- I've only configured the FTP connection, the folder and the file name. I don't understand why it isn't working...

Yes I got this message:
Polling interval started. Length: 5,0 seconds
Now I tried something... In the FTP Connection parameters, I set as the server a random and unexisting name, and I get the same result...
I'm starting to thing that some firewall is blocking the connection, but I have to wait until next monday to know this. But I don't understand why the receiver FTP channel is working...
PD: The cache is correctly refreshed because I changed the polling interval time, and it has been updated on the monitoring

Sender File Adapter Not Showing in Decentral Adapter Engine

Hi,
We have recently implemented a Decentral Adapter Engine on a windows box. The adapter engine seems to be working fine because my adapters show and seem to work fine in it.
However, when I define a Sender File Adapter that uses File Content Conversion message protocol instead of just File messaeg protocol, the adapter does not show up in the decentral adapter engine.
I made sure that Adapter Engine parameter in the Sender File Adapter shows the new adapter engine but that does not seem to be working. If change the Adapter Enginer parameter to show the Central Adapter Engine, then I can see the Sender File Adapter on the Central Adapter engine and it works fine. (Note: The Central Adapter Engine is installed on a Unix box)
Here are the paramters I defined for the Sender File Adapter:
- Transport Protocol: File System (NFS)
- Message Protocol: File Content Conversion
- Adapter Engine: (new Adapter Name)
Source Directory: (
server/drive/path)
File Name: purchaseOrder.txt

Your help is much appreciated.

Hi Alaa,
look into this document:
http://service.sap.com/nw-howtoguides -> Exchange Infrastructure -> Troubleshooting: Adapter Engine 3.0 (Expert Call slides)
If the File Adapter works without conversion, then you should count the number of fields in a row. If it differs from the configuration, then it runs on error.
Another idea is to check the content type of the file. When you do not enter a File Encoding, then the file adapter assumes utf-8. If the file is for example latin-1, then the number of characters in a row are not counted correctly.

Stefan

Sender File Adapter picking the same file twice

We are facing a weird issue with File Sender Adapter
We are using PI File Adapter ( NFS ) to read files for a NFS folder and
processing those in PI.Normally it works fine. But for a scenario we
are noticing it sometimes process the same file twice before archiving,
thus duplicating the financial postings.
What we have is :
File Sender Adapter - NFS, Polling interval 60 secs, and Processign
mdoe Archive. File name includes Wildcards - JE_Upload*.txt
what we are noticing is that :
when it picks up a file, it immediately polls again to check for
another file, and sometimes the file is not yet archived so it picks up
and reprocess the same file.
If you see the message below, both belong to the same file, and it
picked up the same file again in 12 secs after processing it the first
time
Successful 02.11.2009 15:01:00 02.11.2009 15:01:01 APMANUAL urn:bl:i2g:003:100
SI_SKF_FIDOC_OB XI Message
Successful 02.11.2009 15:00:49 02.11.2009 15:00:50 APMANUAL urn:bl:i2g:003:100
SI_SKF_FIDOC_OB XI Message
Anyone seen this behavior before?

Hi,
Please check the script which creates file in source NFS Folders. There is possibility that script is making change in file when PI is picking up the file.
When PI picks the file first time it creates one message ID in system. After that if script is making any change in file without file name change (This need not necessary data change), for PI it becomes new file and new message gets generated in PI for same file.
This error normally comes when File adapter is not able to archive file succesfully. For eg. file with same name alredy exists in Archive folder.
File adapter generates the new message id whenfile get modified(eg.change in its length or data change) even though
the file name is same and when file get change ,XI file adapter thinks that its new file and hence generate the new message id for same file.
If file has same name and notmodified then XI adapter will not generate new message id and will keep on throw the error till you remove that file with same name from the
archieve directory.

Gouri
