Appending into File using File Adapter

Hi,
I am trying to write to a file, whenever any data is getting inserted into Database table.
My scenario is like this: I have created a database adapter which is polling for every new record inserted/updated. After this, I am trying to write the content into a file.
The problem what I am facing is, I am not able to append the data what I am receiving from database(Whenever I am inseting new record). Everytime my previous content is getting deleted & a new entry is made into that file.
Is there any way out, by which we can append to a file whenever any new entry is coming into database.
Any possible solution on this..
Thanks in advance...
Abhi..

In order to achieve this follow the steps given below:
1) Open pc.properties located at C:\[BPEL HOME]\integration\orabpel\system\services\config
Set oracle.tip.adapter.file.numProcessorThreads=1
2) Manually modify the interaction spec for the outbound file write and add an extra attribute-value pair as shown below
<jca:operation
LogicalDirectory="......"
InteractionSpec="oracle.tip.adapter.file.outbound.FileInteractionSpec"
FileNamingConvention="MyFinalFile.txt"
NumberMessages="1"
ElapsedTime="60"
FileSize="1024000"
OpaqueSchema="false"
Append="true">
The Append="true" causes MyFinalFile.txt to be appended to everytime the fileadapter is invoked on the outbound.
Also notice that the FileNamingConvention does not have a dynamic part; it has to be a static file name.

How to eliminate inserting Duplicate rows into database using JDBC Adapter

File->Xi->JDBC
In above Scenario if the file has two rows their values are identical, then how can we eliminated inserting Duplicate rows into database using JDBC Adapter

Database is a consumer of a SERVICE (SOA!!!!!!).
Database plays a business system role here!!!!
Mapping is part of an ESB service
Adaptor is a technology adapted to ESB framework to support specific protocol.
ESB accomplish ESB duties such as transformation, translation, routing. Routing use a protocol accepted by the consumer. In a JDBC consumer it is JDBC protocol and hence it a JDBC adaptor.
There is clear separation on responsibilities among business system and ESB. ESB do not participate in business decision or try to get into business system data layer.
So who ever are asking people to check duplicate check as part of mapping (an ESB service) may not understand integration practice.
Please use an adaptor module which will execute the duplicate check with business system in a plug and play approach and separate that from ESB service so that people can build integration using AGILE approach.
Thanks

Row level commit using DB adapter

We have a soa 11g requirement, where a File is polled using File adapter and this is inserted into DB using DB adapter. All the commits should happen
at the record level, where in if one of the record fails due to improper data, the others should commit. I am using a single DB insert rather than looping for
each record in the bpel process. I initially tried with XADatasource, later created a non XA datasource and used it in DB adapter. ALso used the property setting
Idempotent=false. But if one of the record fails, the whole transaction is failed. How to achieve the record level commit?

How to achieve the record level commit?You'll have to redesign your process... One option would be to split your process in two... have a BPEL1 to read the file and send individual messages to a JMS queue, and a BPEL2 to listen to the queue and process individual messages...

How to send XML file into XI using sender HTTP adapter

I am using HTTP sender adapter to post the XML file into XI. I tried to form the URL by using the following String query , but I am unable to execute file.
String urlString = "http://<servername:portno>/sap/xi/adapter_plain?namespace=<namespace>&interface=<interface name>&service=<service name>&party=&agency=&scheme=&QOS=BE&sap-user=xiappluser&sap-password=satyam&sap-client=100&sap-language=EN";
How can I execute xml file by using HTTP sender adapter.
Any one with better suggestions, about this idea?
Thanks in advance for all.
Ram Raj

Hi
Just use the following parameter to send xml file using HTTP adapter.
"http://xiserver:8000/sap/xi/adapter_plain?namespace="senderNamespace"&interface=senderinterface&service=sender service";
"&party=sender party"&agency=&scheme=&QOS=BE&sap-user=userid &sap-password=password&sap-client=100&sap-language=D";
with the help of this you are able to point out which interface you would like to use.
And in payload pass the xml.
and thats it
carry on

Appending in file and supplying file name at run time using File Adapter

Hi,
Can we use File Adapter to write in a file in append mode. i.e. a BPEL process opening a file appending some text and closing the file each time it called.
Another query is can we create the file at run time with the supplied file name?

In order to append to a file, we can use Append="true" in the interaction spec for the File/Ftp adapter.

Hi,
To write a file in append mode, you need to add one line in wsdl file.
Make an entry with Append="true"
inside <jca:operation> tag found in wsdl file, created after Write file adapter.
<jca:operation
PhysicalDirectory="C:\TMP"
InteractionSpec="oracle.tip.adapter.file.outbound.FileInteractionSpec"

How to write a plain string into a file using File Adapter

Hi All,
I am new to ESB technology. I have created one ESB application to invoke a java web service(Which will return string as result) and to write retrieved result in to a file. To achieve it i have created the file adapter using user defined schema. It was working fine. But, I got the modifications in my requirement to store the returned result(String value) in to a text file without any user defined schema. So i used native format for FileAdapter and mapped the returnedResponse(String value) to opaque:opaqueElement. But i am facing relationship error.
anybody can help me to solve this issue?.. is there any method to convert a string value to opaqueElement..
Thanks in advance..

How to write file into multiple directories by using file adapter?

i need to write my file into multiple directories,i able to do in single directory.But i need to write to muliple directories.Please help me out.Thanks in advance.

If you are passing the values at runtime then you can loop it and and invoke the file adapter in loop by dynamically passing the value in invoke properties for "File Directory and File name" etc.

Reciever File Adapter - Temp File Name Scheme using Variable Substitution

How can I create a temporary file that uses variable substitution?
We are having a problem with files merging when we write files using the "Use Temporary File" setting on the FIle Adapter. So two independent files are merging into a single file. We are not using the "Append" setting.
We would like to use a Temp File Name Scheme that would append the message id onto the temporary file name.
Using variable substitution we created a msgid variable. When added to the temporary file name using %msgid% the temporary file name is created with %msgid% in the name instead of the actual message id. We put the variable into the "File Name Scheme" as well and the end completed file used the message id in the name.
Any Ideas?
Thanks,
Matt

HI Matthew,
Why are you adding the message id into the temporary file??
I understand that you want the output of the filename to contain message id .. and hence you are using variable substitution for the same.
Temporary file name will anyways get overwritten by the actual file name (here the actual filename will be using variable substituion).
So i suggest to achieve your scenario you can add any name in the temporary file and maintain the desired filename you require as output in the variable subsititution.
Temporary File Name option actually acts as a lock - unlock mechanism from PI side while the file is getting written to the file server so that while PI is writting the file no third party application batch program picks it up.
I hope this helps.

File conversion and append file in receiver file adapter

Hi
I have a batch IDoc -> XI(3.0) -> file scenario with file conversion to create a flat CSV-like file. The problem is that because of the amount of data sent from R/3 (~20000 employees), the idoc is split into several idocs. In my receiver file adapter I want to append all the idocs contained in this data transfer to one flat file, before transmitting to FTP server.
For the next batch transfer (the next day) XI should start all over and create a new file and append all idocs contained in that transfer before transmitting the flat file to FTP server.
Can this be done using the 'Use Temporary File' and 'Append' options in the FTP connection Parameters in the comm-channel?
It is not an option to append the file in the FTP-server, because the files in the destination folder are moved immediately after arrival, so the file will be moved before file adapter can append all the files.
Does anyone have any suggestions to how to solve this?

How to use File Adapter Receiver to write attachments

Hi,
i have a scenario, in which our own XInotes adapter sends an XIMessage from an IBM Lotus Notes database into XI. This XIMessage contains an XML document as application main document and several PDF files as additional attachments
On the receiver side, i must use a File Adapter to write both the XML documents and the PDF attachments into a directory.
The problem is i don't know how to use the file adapter receiver to write the attachments. In the Channel Monitoring, i can see that all PDF files are transferred to the file receiver. But the file adapter writes only the XML document into the directory.
I've also tried the AF_Modules/PayloadSwapBean, but it can only swap one PDF file into the application payload. And the file name must be hard coded in the module configuration as swap.KeyName.
Could anyone give me any ideas?
thanks a lot in advance
Xiang

hi,
receiver file adapters do not supprt attachments.
Only File Sender adapter is capable of handling attachments not the receiver.

Configuring the sender FILE adapter
The sender file adapter is configured to pick the normal payload (file1.xml), which is specified in the File
access parameters, and the additional image file (file1.jpg) that is to be sent as an attachment is configured
under the Additional File(s) as shown in the screenshot below. The file type would still remain binary.
Since, by default, XI sends payload and attachments in XML format, we need to call two beans, namely the
MessageTransformBean and the PayloadSwapBean to help us is transforming the content to jpeg format
and also change the file extension.
The PayloadSwapBean module is used to replace the application payload of the XI message that holds the
data with another payload which is appended to the message as an attachment. In our case, the payload
would be file1.xml whereas the attachment would be file1.jpg
The swap module is denoted in our scenario with the module key swap. It has two parameters from the
MIME header.

File adapter-How to set line break in text file-split record into two lines

Dear Guru's,
I have to solve following problem with XML (with mulitiple records) to TEXT file scenario using file adapter. I have to output for ever ONE data record in XML always two identical lines in text file. Second line should have a little bit different mapping in few fields like date,... So I did duplicate fileds in my output structure in mapping and need to know how to set line break in the middle and see half of structure in first line and next structure half in second line
My output structure in mapping is:
CASHFLOW
- INTERFACE
- GESELLSCHAFT
- ANWENDUNG
- PRODUKT
- VERTRAG
- BETRAG
- WAEHRUNG
- DIRECTION
- BEWEGUNGSTYP
- FAELLIGKEIT
- ZINSFESTSTELLUNG
- ZAHLUNGSTAG
- RENDITE
- INTERFACE2
- GESELLSCHAFT2
- ANWENDUNG2
- PRODUKT2
- VERTRAG2
- BETRAG2
- WAEHRUNG2
- DIRECTION2
- BEWEGUNGSTYP2
- FAELLIGKEIT2
- ZINSFESTSTELLUNG2
- ZAHLUNGSTAG2
- RENDITE2
Question is how can I set on receiving file adapter in Content Conversion Parameters that fields from first structure half INTERFACE...RENDITE should be outputed in one line and fields from second half of structure INTERFACE2...RENDITE2 should start on second line in final text file.
I'm getting at the moment one line only and I need to know how can set line break so that second line starting with INTERFACE2(CA)...RENDITE2 will start in new line.
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000",CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
This should be final output:
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000"
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
My file adapter settings:
RecordsetStructure=CASHFLOW
CASHFLOW.fieldNames=INTERFACE,GESELLSCHAFT,ANWENDUNG,PRODUKT,VERTRAG,BETRAG,WAEHRUNG,DIRECTION,BEWEGUNGSTYP,FAELLIGKEIT,ZINSFESTSTELLUNG,ZAHLUNGSTAG,RENDITE
CASHFLOW.fieldSeparator=,
CASHFLOW.endSeparator='nl'
CASHFLOW.fieldNames=INTERFACE2,GESELLSCHAFT2,ANWENDUNG2,PRODUKT2,VERTRAG2,BETRAG2,WAEHRUNG2,DIRECTION2,BEWEGUNGSTYP2,FAELLIGKEIT2,ZINSFESTSTELLUNG2,ZAHLUNGSTAG2,RENDITE2
CASHFLOW.fieldSeparator=,
It wont help if I add two identical structures in mapping because in output i would see for multiple entries section with first lines only and after that section with second lines only. And CASHFLOW is one part of more complex mapping ...
(This is final output structure RecordsetStructure=HEADER,CASHFLOW,CONDITION,REFERENCE,CONTRACT - more sections with different data and all these should have duplicate lines at the end)
Thanks a lot for any help
Cheers
Marian

Hi Ivan,
right, I did test just for sure.
Putting constant 'nl' into field CASHFLOW-INTERFACE1 didnt help - still getting one line instead two lines.
CA ,"0100" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,2 ,12 ,2009-01-28 ,2009-01-27 ,2009-01-28 ,"0.0000000" ,'nl' ,"GTP1" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,1 ,10 ,2009-01-27 ,2009-01-27 ,2009-01-27 ,"0.0000000"
So there is still question. Is there any way (mapping,...) how to output always 2 lines in text file for one record in XML. It always does 1 record in mapping structure = 1 line but we need 2 lines ...
Example:
Input: 4 records in XML
Output: 8 lines in final text file ...
Thanks to you all guys

Can I use a schema with no targetnamespace with the file adapter?

I am loading a file using a file adapter configured to use an xsd from a third party, the third party controls the xsd and incoming xml and does not have a targetnamespace defined in the xsd or xml.
When I define a file adapter for it the wizard indicates that I need to fix the xsd by adding a namespace. I dont have control over the xsd or xml as they are an external party.
I think I can hand edit the wsdl and change the import statement that requires a namespace to an include statement with no namespace.
Have you run into this before? Will that work?
Thanks,
John

Hi John,
Did we get any solution for this ?
Even in our case, the third party controls the xsd & incoming xml message. Both does not have a targetnamespace defined. The file adapter wizard indicates that we need to fix the xsd by adding a namespace. As a workaround, we manually added the target namespace to xsd and created file adapater. Now the question is how do we automatically add the name space in xml message as well, so that it can be parsed by BPEL process
thanks
