File Adapter read Operation

I am using File adapter to read files from the given location.
With this read operation it picks all the files at time.
I want to configure File Adapters that it should pick one file at time from the given location with given polling interval.
Can we do this with file Adapters in BPEL.
I am using SOA Suite 11g.
Thanks,
Arun Jadhav

Hi, in order to achieve that you need to set the "SingleThreadModel" and "MaxRaiseSize" properties for your file adapter.
Edit the adapter's jca file and add the following properties:
<property name="SingleThreadModel" value="true"/>
<property name="MaxRaiseSize" value="1"/>
You can set these properties also through jdeveloper, by opening composite.xml, selecting the adapter and then changing the properties through the properties panel.

File adapter Read operation not working.

Hi All,
I have a simple file adapter which will read from a csv file and insert into a table. I have deployed the application successfully, but the application is not reading from the specific location. I am not getting any error in the EM console. Below is the XSD that I used.

Please help friends.

You should extensively practice the samples given in Oracle's documentation guide for modelling Native XSD. That will give you a better idea, about how to go about the native xsd schemas.. Anyways, I looked into your schema.. You need to make 2 changes to make this xsd work..
(1) Change "xsd:choice" tags to "xsd:sequence".
(2) Include a closing tag of "xsd:schema" to make the xsd well-formed.

How to get file name from file adapter (Read Operation)

Hi All,
I am reading files from local location, in jca file i gave filename property =*.* ( which reads all files), and now I want to read the incoming file name inside bpel and I want to copy the file name to some variable. Is this possible?

Yes, its possible.
In your receive activity,set below property in its properties tab:
<bpelx:property name="jca.file.FileName" variable="FileName"/>
Before that make sure to create a variable "FileName" of string type.
Whatever file your file adapter will read,its name will be stored in this variable.
Hope this helps.

Karan

[File-Adapter] Reading not finished files

Hey,
my sender file adapter reading files which are not finished yet.
The files are created by an ABAP programm. The creation could
take some seconds. If the file adapter polls while creation is not
finished, we have a problem.
The flag "Process Read-Only Files" is not set, so the ABAP programm
doesn't seem to set the file to read only.
Is there a way to check (e.g. with an operating system command) if the
file is processed completly?
For example I could check if the date of creation is higher than 10 minutes
or something like this.
Any other ideas?
thanks
chris

What is the file adapter option you are using?
If NFS, you have the option "Milliseconds check before modification" that will prevent the file from being picked up till they are completly written.
If FTP, then when the file is being written to the ftp folder you should have the option to use temporary files option

Can Scheduler be used in ORACLE SOA to trigger FTP Adapter read operation

I need to create an ESB project where scheduler should trigger the File/FTP Adapter read operation.
Where can I provide the time settings viz. (xx HR: yy MM: zz SS everyday)?
Is it possible in Oracle SOA?
Please provide any tutorial where scheduler has been used to invoke the File/FTP Adapter rather than invoking it real time (gets triggered the moment files are placed).
Thanks

You should the quartz timer within the SOA Suite to obtain this functionality.

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.

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>
</partnerLinkBinding>

File adapter SyncRead Operation adds "???" to first record of csv file

Hi All,
One interface is reading one CSV file (containing two fields only) using SyncRead Operation of File Adapter. But I found, when file adapter parsed the data it appends "???" to first field of the first record which cause further data validation in the process.

Can anyone help me to understand , what is reason? Or I missed anything.
Thanks & Regards,
Sharmistha

Unfortunately, this is documented bahaviour (solution/workaround anyone?!):
Elapsed Time Exceeds:
Specify a time which, when exceeded, causes a new outgoing file to be created.
Note:
The Elapsed Time Exceeds batching criteria is evaluated and a new outgoing file is created, only when an invocation happens.
For example, if you specify that elapsed time exceeds 15 seconds, then the first message that is received is not written out, even after 15 seconds, as batching conditions are not valid. If a second message is received, then batching conditions become valid for the first one, and an output file is created when the elapsed time exceeds 15 seconds.

How to configure File Adapter (Read)..?

Hi all,
While configuring the Read Adapter in BPEL 11g i am getting not reading any data from given location. But my location are correct.. So please how to configure File Read adapter and give any URL for this ... Thank you

Hi all,
The file adapter it consists many operations like
1: Read
2:Write
3:Synchronous Read
4:ListFiles
So you are asking about Read operation
First you take one File Adapter-->Select Read Operation--->Give Incomming file Location ( In local system you can give like C:/temp/NewDir Or Unix Envornment like you can give /temp/NewDir)
After that you can give file Name like wich format it's incomming file name like CSV.txt or CSV.xml after you give Polling Intervels second or Mintued or Hour.You can select Native format or Define service Later once configure all those things the file adapter configration is done . If you have any doubts in file configrigation please go for the below link...........

File adapter read activity.

Hi,
is it possible to make the file adapter to look for specific files and ignore others in the same directory or do you have to write a web service for that? I want the file adapter to poll for certain files only.
Best Regards
Johan

Hi Johan,
In the Adapter Configuration Wizard its already providing the setting
You can found the setting as following
File Adapter > Operation Type (Read File) > Step 5 of 7 (File Filtering)
This step allows you to specify the file name pattern of both include and exclude files
Notice: I am using JDeveloper 10g

Difference in File Adapter Read File as attachment and Use File streaming

Hi all,
As part of our POC we created a File adapter using the option Read file as attachment and File streaming we observed below things
1.When we are taking “Attachment” option in file adapter, Its able to archive, but not supporting to write data to different location(using fileadapter’s write operation.)
2.when WE are taking “ file streaming “ option in the adapter , Its not able to achive, but it writes data to different location(using fileadapter’s write operation.)
Can anyone know is this is a correct behaviour . If yes what is the reason .
Thanks

File Adapter Read, Translation error

Hi,
I got problem with BPEL File Adapter. When i'm reading file i got scheme - termineted with semicol and without quoting.
In uploaded test file there was line - first colums;second colums;""third"" column";forth column;
And the problem are five quotes and adapter fails with translation error. Can i somehow ignore them?

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}

Dynamic update to Inbound Directory for File Adapter Read

I've seen references to others asking similar questions but never a good answer.
I have a process that outputs files into daily dated directories. In other words, my Inbound Direct name is dynamic. I would like BPEL to be able to pick up these files but the Directory Spec for the inbound file adapter seems to be set at design time (or in the case of a Logical Directory Deployment time).
The directory names are in YYYMMDD format. So it would be:
importdir/YYYMMDD
for each day.
Is there a way I can monitor an entire subtree, or have some event that triggers the directory name to be updated (for instance, a process watches the parent directory and kicks off when a new directory is created), or any other method I can inform the FileAdapter to begin polling a different directory.
Thanks.

Hi,
Look at this document : [Oracle JCA Adapter for Files/FTP|http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10231/adptr_file.htm#CIAFJCCE]

File adapter : Read poll setting is not picking the file

Hi all,
I created a soa project to read a file and load in to the database table.
File adapter to read file > Mediator > Database adapter
Is the above structure i created. While i created this my imagination is that file adapter has poll frequency to read the file i set the value to 10 seconds.
After i deploy my project i checked in enterprise manager that there is no option to test this , because test button will be disable due to file adapter and database adapter , so no inputs required here. But i feel this will automatically read the file for every 10 seconds. but its not happening.
any help will be appreciated.
Thanks,
Sabari
Edited by: 933406 on May 25, 2012 3:49 AM

You have to have cluster id property setting on composite level and deploy. This will restrict reading twice.
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="readCustomersFile">
<property name="portType">Read_ptt</property>
<property name="clusterGroupId">ProcessClusterID</property>
<property name="InvoiceInboundInput" type="LogicalDirectory">/path/</property>
<property name="InvoiceInboundArchive" type="LogicalArchiveDirectory">/path/</property>
<property name="rejectedMessageHandlers" >file:////path/</property>
</activationAgent>
</activationAgents>
