Two File Adapter

HI.
Our system have two instances, and we use file adapter(sender). These file directory is same.
If the two file adapter try to get file at same time,
does the locking error may occurred?
Have anyone met the this kind of problem?
regards,

>>If the two file adapter try to get file at same time, does the locking error may occurred?
I guess you would not get any locking error as the file adapter does not support the file locking.
For more information on file locking have a look at the note 821267 Question 3.
From SAP Note
Q: I sometimes observe that files are processed only partially,
i.e., only a fragment from the file's start is converted into an XI
message. Nevertheless, the file is usually archived completely.
Does the File Sender Adapter honor if another process has locked a
file for exclusive use?
o A: Unfortunately, the J2EE 1.3 technology the File Adapter is built
upon does not support file locking. This limitation affects the
File Adapter's operation. Depending on whether the JRE
implementation for the operating system under which the adapter
runs uses mandatory file locking or advisory file locking, opening
a file that is currently being written to by another process will
fail or not.
If opening the file fails, no problem exists and the adapter will
try to open the file each poll interval until it succeeds.
However, if opening the file is not prevented by the operating
system, the adapter starts to process the file although it is still
being modified.

Same setting for two file adapter but different output

Hi ,
I am having two receiver file adapter for two differrent scenario with same settings but different structure.
I want the output of the file for both the scenario should be displayed line by line but it is working fine for one scenario.File type,file encoding and FCC are same in both the interface except the fieldsnames in FCC.
When i check both the output file i found that the scenario which is working fine having OA OD hexadecimal value at the end of line of each line.and the second scenario which is giving the output in single line is having only OA.
waitng for Valueable inputs!!!
Thanks
Santosh

Hi Santosh,
Kindly elaborate your question.
it would be helpful if you post the content conversion parameters of the erroneous file channel.

Testcase problem using two file adapter and a transformation

We've got an input which looks like this :
<?xml version="1.0" encoding="UTF-8"?>

<row>

<naam>A</naam>
</row>
<row>
<id>20</id>

</row>
</rows>
I've created an XSD for this message which looks like this ( straightforward ) :

          </simpleType>
     </element>
</schema>
I've imported this XSD in my ESB project and created a file adapter which reads this type op files.
I've created another file adapter to write the files 1:1 to an output dir.
In the routingservice I've created a very straightforward XSL mapping which maps everything 1:1.
Now the problem
When I use this input :
<?xml version="1.0" encoding="UTF-8"?>
<rows>
<row>
<id>10</id>
<naam>Martin</naam>
</row>
<row>
<id>20</id>
<naam>Edward</naam>
</row>
</rows>
my output result is:
<?xml version="1.0" ?><imp1:rows xmlns:imp1="http://www.test.nl/testschema"/>
I know this is a namespace issue. When I add the namespace
<?xml version="1.0" encoding="UTF-8"?>
<rows xmlns="http://www.test.nl/testschema">
<row>
<id>10</id>
<naam>Martin</naam>
</row>
<row>
<id>20</id>
<naam>Edward</naam>
</row>
</rows>
I get the correct ( and 1:1 output ).
The problem is. In the scenario I'm about to build the input xml messages do not have an namespace. How can I alter my xsd file or anything within my ESB project that all files will be picked up correctly and processed without having an default namespace?
Any help is appreciated!

True,
But its the other way around what is causing my problem.
Because the input xml files contain no namespace at all the xml messages are transformed but result in an almost empty xml message. ( e.g. the root element is there and thats it ).
This is because the XML transformation mapper in ESB ( as well as BPEL ) excplicitly needs a namespace.
I solved it by editing the XSL by hand, removing the :imp1 namespace prefixes in the select="" tags. e.g.
<xsl:for-each select="/imp1:rows/imp1:row"> is updated in
<xsl:for-each select="/rows/row">
As far as I know this is the only workaround at the moment that I could find.

Two file adapter questions

First, can someone post a URL for detailed file adapter documentation?
Second, I'm a little confused how to use the file adapter in the case where I'm writing out a message whose schema is contained in one of the wsdl files instead of in an xsd file.
The particular case is that I call the Google search service, which returns a message of type doGoogleSearchResponse. The schema for this message is embedded in the google.wsdl file from Google. When I browse in the file adapter wizard to choose a schema for the write operation, I can only see schema from my projectName.xsd file, none from the google.wsdl file (even though it's in the project). How can I use the file adapter to write out the Google search reply?
Thanks,
Bret

Hmmm. Step 4 of the file adapter wizard requires me to specify a "Message Schema". There is no apparant way to get past that step without choosing one. Should I just choose any schema in the project and then go back and fix the code?

REG: File Adapter

Hi All,
I have a scenario where i need to pick 2 files from 2 different folders and process them in a particular sequence. Can anyone suggest me a method how this can be achieved.
Thanks,
Siva.

use two file adapter with different polling intervals.
first file adapter will pick up file then second adapter will be polled and will pick the another file from the folder.

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

Any pointer will be helpful.
Thanks,

Hi,
You are mentioning the wrong keyfield values i beleive.
RECORD_SET1.keyFieldValue 1     --- > on place of 1 enter the exactvalue which you want to use as key field.
RECORD_SET2.keyFieldValue 2     --- > same apply here.
As adapter is unable to find 1 or 2 in as keyfield in record its sending the empty document.
Try :
RECORD_SET1.keyFieldValue = P CONTRLT00010
RECORD_SET1.keyFieldValue = P CONTRLT00020
I hope his might help u.
Thanks.

Receiver File adapter : two choices "Directly" and "Use Temporarly file" ?

Hi All,
I am writing the file into a folder and I want to write the file completely into the folder.Once the file is placed , one tool will be keep on picking files every second from this folder.So I need to put the file after filling entire data.
In the File adapter, the put file option has two choices "Directly" and "Use Temporarly file".
"Directly" option will serve my purpose?
Which option I need to keep for Empty-Message Handling "Write Empty file" or "Ignore"?
Thanks
Seema

Hi Mohamad,
>> You need to place in the some other folder and do the transfer completely and move the file to desired location using command line parameters as recommended in the previous answers.
I will be posting all the files as .txt files. Can we move the file by using command line parameters for FTP connection?
I heard that we can get do it only for NFS and we cannot do for FTP connection.?
Can you please suggest the command line how to use it.
Thanks

Two Files merging using File adapter in Bpel 2.0

Hi All,
I have two different files (File 1 and 2) of same format(Two columns each) , now i want to merge these two files using their data and form a consolidated file (File 3 with four columns).
Please advise on how to make it possible using file adapter.
Example:
File 1 Format: A1 and A2 - are two columns of number and sring type
File 2 Format : B1 and B2 - are two columns of number and string type
Consolidated File 3 Format : A1 B1 A2 B2 - forming a single row if A1=B1 and also populating A2 and B2.
Thanks
Karthick.

Hi Karthick,
I would say read both files completely. Then create a transform and select both messages as an input creating one output. With XSLT it should not be too hard to combine the two inputs. You could loop on one file and then select each row from the other file. That output can be written to file.
I don't know what triggers the process, but you could either let bpel be triggered by the polling on one file and read the other synchronously. Or read both files synchronously.

Martien

Pick activity is not working properly while creating two or more file adapt

Hi,
pick activity is not working properly while creating two or more file adapter for bpel process.
bpel process compiled and deployed succesfully but while observing the wsdl file of deployed process you can find only one file adapter. so it polls only from that location.
can anybody help on over this? or it's limitation of jdev to use only one file adapter at time while using Pick.
Thanks

Does anybody tried this?

SAP XI - Combine Two files as one in File Adapter

Experts,
I want to combine two files as one in File adapter itself. I am using a simple scenario of File-to-File where i am just sending the file from sender to receiver as it is , EXCEPT, i want to add one line at the end of the file .
I was thinking of doing this in File adapter , avoiding any mapping program in Integration Repository ..
ANY INDEA's ??
Regards,
Ashutosh

Hey
You have 3 options,first one can be to execute a OS command before message processing or use adapter modules to append the new line in the sender adapter.
the second option(and better one) is to do this via message mapping.
third option is to write a OS script and execute it after message processing on receiver file adapter.
one thing you need to make sure is that since OS scripts run on XI server itself(not on FTP server) so in case you are picking file from FTP server and delivering to FTP ,then you can't use option 1 or 3,you can only use option 2
Thanx

Two sender file adapter

Hi.
We have two instances(central instace, dialog instance) on another hosts.
Becase of we want use sender file adapter, so we need place the file data on shared directory that the two instances can access it.
In this case two sender file adapter try to catch the file,
does the locking ploblem occurred?
regards,

Hi,
Yes it may cause the problem while reading the sender file.
The two instances will try to access the file ...it means you have processed the Sender fiel adapter as per File transfer....
But if youhave used the polling interval then...there will not be the problem...as only one instance will work for this.
Thanks

Multiple Exclusion Criteria[Exclusion Mask] in Sender File Adapter

Hello All,
I have a requirement to specify multiple exclusion criteria in the 'Exclusion Mask' property of a Sender File Adapter, i.e. I need to pick up files that correspond to 111*.txt from a specified source directory, but I would also want to exclude specific individual files that go by the following names:-111ACC.txt, 111INV.txt & 111PUR.txt.
I have tried the following - Specified 111*.txt in the 'File Name' field and in the 'Exclusion Mask' field specified ACC, INV & PUR - the exclusion criteria separated by commas. But this does not seem to work. All the 111* files are getting picked up.
Have gone through a couple of weblogs that deal with exclusion masks, but they do not talk about multiple exclusion criteria.
Is there any other way I could accomplish this?
Thanks,
Anand

Hi,
Try this config.
Give *.txt in filename. and Directory as <YourDir>
In exclusion mask give 111ACC.txt
Below this there will be a table. Add two Entries
Dont add anything to FilenameMask.
Directory ->FileNameMask--->ExclusionMask
<yourDir>->--->111INV.txt
<YourDir>->--->111PUR.txt
Try this and get back.

Questions about using FILE adapter to connect to other systems

Hi,
in my PI scenario i am facing a problem in usage of the file adapter.
Our PI system is installed on a UNIX server. The target system for upload an download files is a WINDOWS system. The software installed on the WINDOWS system is only able to export the needed file lokal on the WINDOWS server.
Between UNIX systems i can connect a together used fileshare folder. But this won´t help me in my UNIX <> WINDOWS scenario.
I thougt on using an FTP server on the WIDNOWS system to make the PI able to connect via the FTP adapter but this works fine for one or two systems. I don´t think that this ist the best solution when connection to a lot WINDOWS systems, but mayby i am wrong.
Actually i use UC4 to copy the files between the two systems.
Any ideas how to deal generally with such scenarios?
Many thanks
Michael

Even though if you map Unix and Windows OS to read the files, in the long run the design will put you in trouble. Means it requires constant support. Better you go with unix script as per the above suggestion.
