File Adapter Write missing files

Hello
I have some trouble with a bpel process containing a file adapter that should write files to disk. Each bpel-process is started when a read file adapter reads a new matching file (*.xml).
I have tested the process with a few files (5-20) and a new process is started for each file, and at the end of the process a new file is written to disk by the file adapter (Write). But when I am testing with a large number of files (40-50 files) something strange happens.
A new process is started for each file, but it looks like the file adapter that should write files to disk is not capable to handle the pressure. 10-20% of the processes doesnt complete as expected. In the BPEL Console everything looks ok, it seems like the File Adaper has written a file to disk, no error is trown. But when I look in the directory the file is not there...
Has this something to do with performance? Is there any parameters or settings I can tune to make the file adapters work better? Sometimes it also looks like the file adapter (read) doesnt manage to start a new process for each incomming file even if they are deleted and archived...

I ran into a similar issue. As a workaround we ended up just using java to write the files out. When the File Adapter attempts to write out a file it first writes that file to a temp file and then copies that to the appropriate directory.
I believe that when two or more threads were attempting to write at the same time the write was failing for one (but appearing to work in the console logs). I think a race condition may be created when two threads attempt to write using the File Adapter for access to the temp file. I contacted my oracle rep about it but they are always pretty worthless so I havent ever heard anything back concerning the issue.

File Adapter write XML file with special characters

Hi,
I have a BPEL processes which use DB adapter to retrieve record and output in a XML document using File Adapter.
In the table, some records contain these special characters - ">" , "<" , "." . I was expecting the file adapter will convert it to escape characters, but it didn't happen. it just put the same value back to the XML file, which cause other system to reject the file. Do anyone know how to resolve this ?
The version of SOA is 10.1.3.4
Thanks for the help.

one option is to specify validateXML on the partnerlink (that describes the file adapter endpoint) such as shown here
<partnerLinkBinding name="StarLoanService">
<property name="wsdlLocation"> http://<hostname>:9700/orabpel/default/StarLoan/StarLoan?wsdl</property>
<property name="validateXML">true</property>

File adapter picking up files with wrong content

Hello, We configured a file adapter to read *.xml files. We also defined the xsd for the files. We expected that the adapter would only pick up files that conform to the xsd. However we found that all *.xml files (even renamed jpeg's) are read. Is this intended behaviour? Or did we miss some configuration setting?
Richard

A short follow-up:
To make matters worse. If I take a completely different file (like the jpeg) and rename it .xml it gets picked up by the file adpater but there is no audit trail of the BPEL process instance. The file is not archived either, so it's completely gone! If I just change one of the elements the file is read and archived. I can also have the file adapter write the file with the wrong content.
I found a reference to a bug. (bug 5926809 or SR 6327165.994) is this related, is it solved?

File Adapter not processing Files which has COMMA in it

Hi Experts,
I am working on Project in SOA 11.1.1.6.
I am trying to process a file which has comma in it. for eg - XXXXXXX-XX_XX_XXX11,99.pdf
I am picking the file using file adapter from SOURCE directory and using another file adapter to WRITE to destination directory. Polling processing is working fine.
I am picking the file from SOURCE directory as ATTACHMENT and WRITING to DESTINATION folder through File Adapter
While doing file WRITE its failing. While reading the file the values of Content Type, Character Set and Encoding are NULL for the ATTACHMENT as they are optional properties.
The error I am getting while File WRITE is
<remoteFault>
<part name="summary">
<summary>java.lang.RuntimeException: Failed to decode properties string att.encoding=null,att.charset=null,att.contentId=AReadFile/XXXXXXXX_XX_XXX11,99.pdf_1352184009640,att.contentType=null,att.partName=attach</summary>
</part>
<part name="detail">
<detail>1</detail>
</part>
</remoteFault>

Comma is usually treated as a separator/delimiter and hence it is not really common to have comma in filename. I think because of this reason File adapter does not support it (have to cross-verify). If you really have a requirement to read/write files with comma in filename then better log a SR with Oracle support.

File Adapter : read XML file with data validation and file rejection ?

Hello,
In order to read a XML file with the file adapter, I have defined a XSD that I have imported to my project.
Now the File Adapter reads the file correctly but it does not give an error when:
- the data types are not valid. Ex: dateTime is expected in a node and a string is provided
- the XML file has invalid attributes.
How can I manage error handling for XML files ?
Should I write my own Java XPath function to validate the file after is processed ? (here is an example for doing this : http://www.experts-exchange.com/Web/Web_Languages/XML/Q_21058568.html)
Thanks.

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 Stores temp file?

I'm assuming a sender file adapter will store a copy of the retrieved file in the OS somewhere. Does anyone know where this file would be stored and does it only exist until the adapter has completed processing of the file?

Sorry folks I don't think I was clear in my original question. All I want to know is when the sender file adapter connects to some remote system to retrieve a file...
1) Does XI physically move the file to the XI box (regardless of the archive/delete/test setting) or does it simply load it in RAM? For the adapter to be able to process the file my assumption is that it has to be loaded somewhere on the XI box.
2) If it physically moves the file to the XI box where does it temporarily place it?
I'm aware of the archive setting and other options for creating local copies. I just want to know the "inner workings" of how the sender file adapter moves the files.

About Final Cut ProX: why a red line appears at the top o a file imported into a New Event? then when I restarted the Project that files comes as "Missed files" How can i fix it?

Where are you importing from – a camera or computer? If you are optimizing at import, make sure the background processes are completed. (Command-9)

How to use File Adapter to transport files

Hi,
Can i use File Adapter Additional Files settings to Transfer files from one system to other without conversion?
File Adapter's Additional Files documentation says "additional attachments require a receiver that can process them". In my case receiver is also
File Adapter.
Please let me know if there is any other way to achive this.
Thanks in Advance
Jayant

Hi Jayant -
Here is the link to the documentation related to this:
http://help.sap.com/saphelp_nw04/helpdata/en/3c/b4a6490a08cd41a8c91759c3d2f401/content.htm
Notice in "Rules for Additional Files":
"Messages with additional attachments require a receiver that can process them."
Currently, the receiver file adapter does not support the processing of attachments.

File Adapter Writting and Reading strategy

Hi All,
When i am trying to write data to file, it was opened by another person and it gave error in the receiver communication channel saying like source is using by another application. Which is well and good
But in case of Sender channel while writing the data to file even thought it is opened by another person, Sender file adapter is picked the file.
I didn't get the reason why it is like this. Any one of u had the same issue???
Regards

Hi Neetesh,
>>hmm ... that's weird ... you mean to say that the polling frequency is now (20 + 100) = 120 secs ? Unless and until the file is not being modified or the file is not "open", this parameter shouldn't work ...
Examples
Poll interval is 20 sec and MSecs to wait is 100000( 1 MIN 40 Sec)
1) If file is there and did not opened / modifying
waiting till 1 min 40sec to pick the file
2) If the file is there and Modifying it
Adapter is waiting 1 min 40sec if the files have been changed.
3) If there is a file and just opened, not writing any files
Waiting for 1 min 40 sec to pick the file
>>Can you share the adapter log?

File adapter write to network drive fails

Hi all,
I have a problem using the FIle adapter. The situation is as follows:
- SOA Suite 10.1.3.5.0. installed on Windows
- SOA Suite runs under windows user soaadmin, a user with local admin rights.
- A network share is mapped as a network drive on a remote (windows) server, assigned drive letter 'T'.
- user soaadmin is added to a user group on the remote server that has local admin rights on the remote server.
- In my BPEL process, the file adapter is configured to write files to 'T' drive.
- At runtime, ORABPEL-11054 occurs: Directory cannot be created successfully. Directory: T:/ cannot be created successfully.
- If I configure the file adapter to write to 'C' drive all functions well.
- From the windows explorer, user soaadmin can create files on 'T' successfully soa apparently has the right privileges on 'T'.
Any clue as to what may be wrong?
Thanks in advance,
Regards Rob

please use FTP adapter instead of File Adapter.
Thanks,

XI3.0 Receiver file adapter write to windows shared drive

Hi,
Our XI server SP09 currently runs on windows 2003 server, I wish to use the receiver file adapter to create a file on another windows server. I have created a folder on the other server and set permissions so that anyone can read and write to it.
The communication channel has been set-up with a target directory of //server/shared_folder/folder and a transport protocol of 'File system(NFS)'
When I try and send an XML message to the file adapter I get the following error on the runtime workbench :-
Last message processing started 09:47:10 2005-06-09, Error: Message processing failed with java.lang.Exception: Message processing failed - configuration error in file receiver adapter (Directory does not exist / cannot be created)
My questions are as follows :-
a) Do I have the target directory on the communication channel set-up correctly? i.e. do I use / or \
b) What username will need to be set-up on the other server so that the file adapter can write to the shared folder
c) Is there another way of providing user and password information for connecting to the other server?
Many thanks
Ian

Hi Ian
as i understood from ur description is that u want ur file to b generated in some other machine then u have to mention that machine in ur SLD using correct specification..

File adapter(write files with same extension as we read them)

Hello
I am trying to read file as an attachment using file adapter (it can be of any extension .pdf,.txt,.xml)
I want to write this file using file adapter with the same extension i.e. whatever is read as it is....I am least bothered for reading the content inside the file so am reading it as an attachment..
Please if anyone knows the answer..reply....

File Adapter Write Operation inserts a new line at the end

Hi,
I am using the write operation in the File Adapter from BPEL Process. The data is written successfully to the file and file is also created in the location specified in the adapter wsdl. But in the file created, it creates a new line at the end of the file. This new line has to be avoided when writing data to a file.
Has anyone faced this and solved this ?
I am SOA 10.1.3.4.

It is a bug in 10g and will be resolved in one of the versions of 11g.

File Adapter Write Compilation problem JDev 11.1.1.6 and BPEL 2.0

Hi,
Im creating a simple BPEL Project with a One-way Process template project.
I have added just one Partnerlink with a File Adapter to do a write operation.
I have assigned the main process input to the file Write Invoke operation.

The error seen in your case typically occurs when the schemas of BPEL valriable and the schema of message in file adapter WSDL are different. You may use a transform activity in BPEL to map the fields of the two schemas.
You may also like to have a look at various file adapter examples at
http://java.net/projects/oraclesoasuite11g/pages/FileAdapters
These samples provide working examples of how to handle various kinds of data when using file adapter.
