File adapter - delete empty/small files

Hi, are there any way to configure the sender file adapter to delete and not pick up empty files or files with, say, max. 4 bytes of size?
Thanks!

hi Rune,
if the file is empty it will be deleted
in standard (with the file adapter)
no need to do anything
and it will not be processed by the XI
if you want to check for small files you can use this approach:

File adapter with empty files!

Hi guys,
My scenario is: File -> XI (BPM) -> JDBC
Under BPM I have a fork with two parallel receivers correlated and two sender file adapters for that. Those senders also have file conversion (.seq file to XML).
My problem is: in case of files coming empty, is it possible that senders file adapter generates error during file conversion? And/or generates errors during correlations?
If so, "I wouldnt like", because after receive these two files I have a switch to check if the file(s) coming empty and a control step to terminate the process in case of true. But this only works if no errors have occurred on the earlier steps!
At this moment I cant test it, so Im asking If anyone has faced an issue like this one?
Thanks in advance,
Ricardo.

Hi,
Which SP are you on?
Before Sp19 on XI 3.0 and SP10 on Pi, Empty Files are ignored by XI. The file adapter picks the file and if it is a empty file ( a zero byets file ) the file does not create a message at all for the file.
From Sp19, the file adapter has options that allow you to decide how to process the empty file. You can create an error message etc.

File Adapter polls all the files from the directory when deployed again

Hi,
File Adapter polls all the files from the inbound directory irrespective of the timestamp when deployed again.
For ex. when the BPEL process with file adapter is deployed, it starts polling the directory based on the timestamp as and when the directory is written with the files. I did not opt for deleting the files after read by the File Adapter.
But, when BPEL process is modified and deployed again, this time, the file adapter picks up all the files in the inbound directory and doesn't consider the timestamp.
My guess is that it should not pick all the files but based on timestamp only.
I guess I can observe the same behavior if I bounce the Application Server also
Do I have an option to achieve this?
Thanks,
Sasi Bhushan.

try this:
1- create a File object for the directory. (look at isDirectory() )
2- create a File[] that represents the files in that directory. (.listFiles())
3- if (file[x].isDirectory()) {recursive method call;}
4- else {
process file;
If you want more help--do some work on it, and come back with specific questions relating to specific lines in your code and specific error messages you've been receiving.

File Adapter Not picking the files

Hi All,
We have a process wherein the file adapter picks up the file from a particular location and it processed thereafter. We get the files once every month. We noticed that if the files that are being dazzled are of the same, i.e if the same nomenclature is there for the file that was dazzled the previous month, the adapter does not pick up the file. Only after renaming the file, it picks the file and processed them.
Any idea why the files that are dazzled with the same name are not being picked up.
Thanks in Advance...!!

Hi,
While configuring file adapter to pick up the files cross verify with file name putting in the directory location against the
"Includes files with name pattern" "Excludes file with name pattern" file name..
let say if u kept .*txt if picks the files txt with any name and one more think once after picking up the file from particular location are u enabling (delete file once read) option in configuration(It all depends on ur req)..
cross check the schema element of the file pattern.

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.

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.

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.

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

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.

File Adapter to read Zip file and send it as input to another webservice

Hi,
I have the below requirement:
1. A service will generate 3 attachments and place it in a particular directory.
2. SOA service has to pick those 3 files and send those files as input to another custom application which will email.
Design :
1. First SOA will create an archive file of those 3 attachements and then file adapter will poll for that zip file in that location and send that file as a whole to the custom application.
Query:
Now my question, is the above design feasible? If so, how to configure the file adapter to pass the file as input to that custom application?
Kindly do the needful
Thanks,
Priya

You can accomplish this via java embedding activity...Create a java embedding, which will create a zip file.. this java code is easy to implement..
You can also do away with un-necessary polling file adapter.. and you can use "Synchronous File Read" operation of File Adapter.. For Sync Read, you'll have to pass the zip file name, which you can easily fetch from java embedding activity..
Let me know, if this doesn't work.

File Adapter is not polling File.

Hi All,
I am using file adapter to poll a file. When I am restarting server then it is picking file. After then when I am dropping a file then File Adapter is not picking File.
Can any one guide me what si problem?
I am using SOA SUITE 10.1.3.4
Thanks in Advance.

First clusterGroupId is a unique value. Do not use the same clusterGroupId across different adapters even in different process.
Once clusterGroupId is defined, the multiple activations of the same adapter Activation Agent is to be detected implicitly and automatically by all the instances of the adapter framework active in that cluster. The cluster will allow onlye one node activation to start the reading the files/messages. The adapter framework instances chooses one among multiple nodes, randomly to assume the Primary Activation responsibility. The other activations (instances) in the cluster will initiate to a hot stand-by state, without actually invoking EndpointActivation on the JCA resource adapter.
If a primary activation at some point becomes unresponsive, is deactivated manually or if it crashes/exits, then any one of the remaining adapter framework members of the cluster group will immediately detect this, and reassign the primary activation responsibility to one of activation agents standing by.
This feature uses JGroups underneath for the implementation, hence the clusterGroupId property. These features require cluster and JGroups configuration in collaxa-config.xml and jgroups-protocol.xml. All BPEL instances participating in the cluster must share the same cluster name in collaxa-config.xml,and the same multicast address and port in jgroups-protocol.xml.
As far as for this issue, I too face the same across diff environments and searching for the exact reason. I believe this happens when primary activation agent crashes, the hand-over to the other node is not happening properly through jgroups.

XI File Adapter sending/receiving zip files

Can the XI File Adapter create a zip file to send outbound from XI and/or can it also translate a zip file inbound into XI?

Hi Kirk.
What you can do is use the OS command option on the adapter in order to unzip the file after the File\FTP adapter completes its file transfer to the specified path.One of my colleagues used a freeware zip app. that excepts an os command actions.
I know it works for file receiver but not sure about the sender. check SAP Note 801926 for more sender adapter parameters.

File adapter reading while the file is still being written....

Hello BPEL Gurus,
I had a quick question around BPEL or ESB file adapter. Does BPEL file adapter starts reading a huge file that is being written or it waits until the writing process is completed and file is complete?
Any response is highly is appreciated.
Thanks.
SM

It goes like this. At every polling frequency, the adapter looks into the directory for the files with specified pattern (e.g. *.csv, MYCOMPANY*.txt) and specified condition, e.g. minimum file age. This means if there will be 2 files available with matching criteria, the both will be picked up and processed simultaneously in two different BPEL instances. No specific order of execution. However you will find the instances in BPEL console with little delay based on file size.
Perhaps you can elaborate your scenario further. Do we have knowledge of the file name that are to be picked up from the folder. You may use synchronous read option. If you are using 10.1.3.4 version then you can specify the file name before file adapter makes a synchronous read into the give directory.

NFS File adapter donu00B4t generate log file.

Hello!
We have a problem with a File adapter. when adapter catch file, this one don´t archive this file into archive directory.
We have:
Processing mode: Archive.
Archive directory : /XIcom/INT181_GECAT/LOG
This directory is created correctly.
Someone can i help me. Thanks.
Best regards.

Hi ,
>>>NFS File adapter don´t generate log file
Do you mean you are not getting the processed files archived only when the file adapter set to NFS File system ?
Did you try same thing by setting File adapter as FTP ?
If you face same issue with File adpter set in FTP mode also then there is some issue with access to the folders.
Please check this ...

Receiver file adapter creates empty files, Empty-Message Handling SP19

Hello,
We have just upgraded the system to SP19.
One of the new features is that it should be possible to determine how XI messages with an empty main payload are to be handled in the receiver file adapter.
If the parameter Empty-Message Handling is set to 'Ignore' no file should be created if the main payload is empty. In our case an empty file (size 0 kb) is still created even though the main payload is empty and the flag is set to 'Ignore'.
Has anybody experienced the same problem?
// Best regards Hans

This should work:
Use your own adapter module that parses incoming message and checks if it has any record sets in the document. If it does not have any record sets, then set the message to empty and then give this modified message to File receiver.
For example, see the example code below:
Module imports..
Audit log import..
DOM imports/SAX imports..
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          try {
               // get the XI message from the environment
               Message msg = (Message) inputModuleData.getPrincipalData();
               AuditMessageKey amk = new AuditMessageKey(msg.getMessageId(),AuditDirection.INBOUND);
               Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"RemoveRootTag: Module called");
               XMLPayload payLoad = msg.getDocument();
               Document doc = parseXmlFile(payLoad.getInputStream());
               if(doc != null){
                    if(!doc.getDocumentElement().hasChildNodes()){
                         Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Document is empty!!");
                         payLoad.setContent("".getBytes());
                         msg.setDocument(payLoad);
               // provide the XI message for returning
               inputModuleData.setPrincipalData(msg);
               } catch (Exception e) {
               // raise exception, when an error occurred
               ModuleException me = new ModuleException(e);
               throw me;
               // return XI message
          return inputModuleData;
     private Document parseXmlFile(InputStream xmlpayload) {
          try {
               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
               factory.setValidating(false);
               //        Create the builder and parse the file
               Document doc = factory.newDocumentBuilder().parse(xmlpayload);
               return doc;
          } catch (SAXException e) {
          } catch (ParserConfigurationException e) {
          } catch(IOException e){
          return null;

Text Content Conversion - File Adapter - Creates empty file

I am running XI 7.0.
Mapping from abap proxy to file - text content conversion.
The process works, generates and sends file from mySAP, maps through XI, logs onto ftp site and creates file, but doesn't write any data into the file!
I am really confused as to what is happening!
This is taken from the communication channel!

hi,
this is starange:)
did you refresh FTP (F5) ?
maybe you're checking wrong ftp server? with the same folders ?
ups - I thought I doens't create any file...
as suggested check your mapping as per my blog:
/people/michal.krawczyk2/blog/2005/09/16/xi-how-to-test-your-mapping-in-real-life-scenarios
just use TCODe for abap mapping tests - SXI_MAPPING_TEST
