Invoke File Adapter to read just once.

Hello all,
I want to invoke a partnerlink which is using File Adapter to poll for a file every fixed interval. I want the File adapter to read the file just once. In other words, what would be the behaviour of the File Adapter when i invoke it syn or asyn way? Would the file adapter read the file only once? Is there anyway to do this? I read in some post about it but i cannot find or recall the thread.
Thanks for your help.

I think I need to explain the scenario in order to give you some more idea as to why i need to poll file just once.
I am trying to create a schedular using Quartz and If i have this BPEL process scheduled to trigger at say some time, the process would keep on polling. Whereas i just need to poll when the trigger is fired that is once per every trigger fired.
Can anybody throw some ideas on this?

File Adapter and reading all XML files from direcotry

Problem occurs on PI 7.1
I defined sender file adapter. File name mask is: "*.xml" to read all XML messages from directory.
Quality of service is: Exactly One.
Poll Interval: 30
Retry interval: 30
Processing mode: Archive with option "Add Timestamp".
Processing sequence: by name.
I though that with above configuration my File Adapter will be reading folder for all coming XML files. But somehow it is reading XMLs only when I'm activating it in Integration Builder.
Any idea what can cause such strange problem?

Hi Tomasz,
As per my understanding, you need to activate the file adapter for reading the XML files on your directory. Right?
If that is the case, then the issue might be with the Cache.
1. Clear the cache from the Integration Builder.
2. Check in SXI_CACHE whether there are any issues. Click on Delta Cache refresh to find out if there are any cache related issues.
Thanks,

FILE ADAPTER NOT READING FILE.

HI, GUYS.
I'M USING A FILE ADAPTER TO READ A FILE THAT HAVE 4 REGISTERS AND EACH REGISTER ONLY HAS ONE FIELD THAT IS NUMBER TYPE.
I CREATE THE FILE ADAPTER, AND I LET BPEL TO CREATE THE SCHEMA. THE IDE CALLS THES FIELD "C1". I ALSO CONFIGURE THAT THE FILE THAT MUST RAD IS THE PATTERN "*.TXT" AND EVERY 5 SECONDS.
THEN A CREATE A RECEIVE ACTIVITY THAT RECEIVES WHAT WAS READ FROM THE FILE ADAPTER IN A VARIABLE.
THEN I CREATE AN ASSIGN ACTIVITY AND I ASSIGN THE VALUE FROM THE RECEIVE ACTIVITY VARIABLE TO A NUMBER VARIABLE THAT IS THE INPUT OF A WEB SERVICE.
THEN I DEPLOY THE BPEL, AND I INITIATE IT, BUT I GOT AN ERROR THAT SAYS THAT THE FIELD "C1" IS EMPTY. SO LOOKS LIKE THE FILE ADAPTER IS NOT READING THE FILE. I WOULD THANK ANY HELP THAT YOU CAN BRING ME.

caps off
You're sure the interface of the fileadapter (client partnerlink) is the same as your data-file which needs to be picked up?
can you paste the content of the file and the content of the xsd of the process.

Sener file adapter has read/pick the files first in first out method.

HI
In my Interface I am Using Sender as File adapter. As per my requirement Sender file adapter has to read the file from file directory. This directory having 1000u2019s of files with some files are same name (time stamp is different) and some files are different name here file adapter has to pick the file with mentioned name in File sender adapter like ZMPSMSGSTATUSMST-.xml .
But source file name is like <TABLENAME>-<TIME_STAMP>.XML (ZMPSWRKFLOWHIST-20090527-150522-628) in file directory.
The file adapter in XI will poll to this directory and picks the file in first- in first-out by sorting according to timestamp.
To do this configuration what I have to do in sender file adapter please give me your valuable inputs.

HI Abhi,
Thank you for your spot replay.
I tested now but i am geting below error.

Hi,
You have use the attribute quotedBy... By default, the specified string is &quot; ("). If your data includes this character, you must override this default even if the field is not quoted.
For example:
{code}
<element name="field" type="string" nxsd:style="terminated" nxsd:terminatedBy=";" nxsd:quotedBy="<"/>
{code}
Read this...

File Adapter Not Reading Large Files

Dear Experts,
Enviornment :-
OS:-Linux
Jdeveloper:- 11.1.1.6
SOA:-11.1.1.6
Weblogic:-10.3.6
JDK:-SUN
Allocated RAM:-16GB
Currently we are in UAT Phase and now we are facingan issue in reading large file.Below is the Design details of the service
FileAdapter(Read)-->Bpel(Business login,Using FlowN)-->FileAdapter(Write CSV),JMS Adapter(AQ JMS topics)
In this case at the time of read itself we are facing issue. File adapter reading xml file but in receive activity receives input data as
xmlDocKey:1C135990067411E3BFA6B5087B629F9DI
I really couldn;t understand about the error. Even i tried reading as Opaque format and still end up with same error.
In order to make sure i have create mediator and tried reading the file, in case i was able to read file upto 15mb with out any error.Also i tried as "read as Attachment" in Bpel component and able to read the attachment upto 7 mb file, but this is hitting the performance side.
I request some one please let me know why the file adapter is giving XmlDOCKey rather then XMLContent to the inputvariable
Regards,
Tarak

Can you check your BPEL Properties in EM?
Go to Soa-infra > right Click > SOA Administration > BPEL properties
increase the Dispatcher Engine Thread = 10, Dispatcher Invoke Threads = 60 and Dispatcher Engine Threads to 90
Click on "More BPEL Configuration Properties"
Increase the DispatcherMaxRequestDepth from 600 to 1000.
Bounce the server and see if works..
Bounce the server and try again.
If this fails, try get a threshold by increasing the file size until it fails again.

File Adapter-Problem Reading Huge Files

Hi,
Here is the issue that i am facing
When reading huge file(csv file upto 6MB-8MB) the communication channel configured as File Adapter with a polling interval of 7 min(420 sec) is inconsistent in reading the complete file.Sometimes it reads the the complete file of 6 MB and sometimes it reads a part of the file say 3MB/6MB.Can this inconsistent behaviour be resolved.??
Your suggestions highly appreciated.
Regards
Pradeep

Hi Pradeep !
8mb is not a huge file for XI, I think it is a small one. Maybe your problem is not the size..please check if XI is not starting to read the file before it is completely written to the source folder. If you are creating that csv file from another application directly to the poll source directory of the XI scenario specified in the file adapter, and your poll interval is small, XI could start reading the file while you are still writing it. If this is the case, try to put the file with a different extension or filename than the specified in file adapter comm channel and when the file is completely written, rename it to its final filename and check if you are still having that misbehavior.
You can write the file to a temp directory and the move it to the XI directory once finished.
Regards,
Matias.

File adapter : automatically read file ?

Hi,
I would like to read a file as soon as it is copied to a folder, without waiting for the polling interval. Is it possible to use File adapter reading capabilities without using the polling frequency ?
Thanks
Message was edited by:
Alexandre Abric

The only way to check for the existence of a file is to do this on a regular basis, i.e. in case of the file adapter with a polling interface. If you have control over when this file is created, you could ofcourse signal the BPEL process another way, maybe by sending a JMS message or invoking a process via SOAP.

How to add do not read file content option inside File Adapter (Synch Read)

Hi,
Is there any way, that I can skip reading the file content inside file adapter with operation as Synchronous Read ( I just want to read the file name and directory and if the file name matches with the input variables then I have to delete the files, for this i am using FA with synch read operation, everything is fine like deletion, but it is reading the file content and storing it in DB, i dont want this) .

This will solve your problem.

Using sender file adapter to read the most current file

Hi,
in my sender file adapter , i have to read the latest file- all files in the source directory are named as <filename><timestamp>.txt . I need to read the file with the latest timestamp (i.e. the most current file )
How do i configure this using file adapter.
thanks

Hi Sreeram,
thanks for the answer- but i found that the option can only be used with NFS transport protocol. what if i am using FTP ?
alos, by date option means- files are processed according to their time stamp in the file system, starting with the oldest file.
However in my case i only want to read the latest file and ignore the older files.
Thanks

Sender File Adapter Error reading file

Hello!
I have a problem with reading a file using the FTP adapter.
I have configured everything according to the steps of weblog "FILE to JDBC Adapter using SAP XI 3.0" (/people/sap.user72/blog/2005/06/01/file-to-jdbc-adapter-using-sap-xi-30).
I know the sender FTP adapter can connect to the directory and file because:
1) it has complained about wrong format in the content conversion (has been fixed)
2) when there is no file for it there to pick up, the FTP flag in the adapter monitor is green
When I put a file in the specified directory I get the following error:
- 2006-06-21 09:52:23 CDT: Retry interval started. Length: 10.000 s
- 2006-06-21 09:52:23 CDT: Error: Retrieving file 'test_file.dat' failed unexpectedly: FTPEx: Public: The system cannot find the file specified.
- 2006-06-21 09:52:20 CDT: Processing started
- 2006-06-21 09:52:13 CDT: Error: Retrieving file 'test_file.dat' failed unexpectedly: FTPEx: Public: The system cannot find the file specified.
- 2006-06-21 09:52:10 CDT: Processing started
I also get the same error if I skip the content conversion and put a "ready" XML file there.
There should be no auth problems at all. Public server, and I can log on, get, put, delete etc. Also it can apparently read it since it can complain about the content format. Anyone seen this before?
Please advise. Thanks!
Nam

Hi Nam,
Is your User Id and User Id/Password is correct ?
Is connection mode is per file transfer in File Adapter configuration?
Also you can see the log from Visual Admin..

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 not reading (not starting polling interval)

Hello,
I've got one communication channel trying to read a file each 10 seconds.
The file adapter is configured correctly and the channel is started but sometimes it stops the polling interval process and I don't know why.
For example the channel was working fine until Friday but with no reason it stopped to attempt to read the file on the directory... what can it be?
And another question. What's the difference about communication channel with "Automatic control" or "Started" manually?

Hi,
And another question. What's the difference about communication channel with "Automatic control" or "Started" manually?
Whenever you create new communication channel in Integration directory and activate it,its status in control data is Automatically and whenever you change it in RWB (Stop/Start) its status changes to Mannually.
Thanks!
