Duplicate namespace declarations when writing a file with JCA file adapter

I am using JCA File adapter to write a an XML file. The composite contains a mediator which received and transforms an XML to desired format and then calls a JCA file adapter to write the file.
The problem that I am having is that the written file has declaration of namespaces repeated with repeating elements instead of a single declaration at root. For ex.
instead of
<ns0:Root xmlns:ns0="namespace0" xmlns:ns1="namespace1" xmlns:ns2="namespace2">
<ns0:RepeatingChild>
<ns1:Element1>value1</ns1:Element1>
<ns2:Element2>value2</ns2:Element2>
</ns0:RepeatingChild>
<ns0:RepeatingChild>
<ns1:Element1>value3</ns1:Element1>
<ns2:Element2>value4</ns2:Element2>
</ns0:RepeatingChild>
</ns0:Root>What I see in the file is:
<ns0:Root xmlns:ns0="namespace0" xmlns:ns1="namespace1" xmlns:ns2="namespace2">
<ns0:RepeatingChild>
<ns1:Element1 xmlns:ns1="namespace1" xmlns:"namespace1">value1</ns1:Element1>
<ns2:Element2 xmlns:ns2="namespace2" xmlns:"namespace2">>value2</ns2:Element2>
</ns0:RepeatingChild>
<ns0:RepeatingChild>
<ns1:Element1 xmlns:ns1="namespace1" xmlns:"namespace1">>value3</ns1:Element1>
<ns2:Element2 xmlns:ns2="namespace2" xmlns:"namespace2">>value4</ns2:Element2>
</ns0:RepeatingChild>
</ns0:Root>So basically all the elements which are in different namespace than root element have a namespace declaration repeated even though the namespace identifier is declared at the root elment level.
Although, the XML is still valid, but this is unnecessarily increasing the filesizes 3-4 times. Is there a way I can write the XML file without duplicate declarations of namespaces?
I am using SOA Suite 11.1.1.4
The file adapter has the schema set as above XML.
I tried the transformation in mediator using XSL and also tried using assign [source(input to mediator) and target(output of mediator, input of file adapter) XMLs are exactly same].
but no success.

I used automapper of JDeveloper to generate the schema. The source and target schema are exactly same.
I was trying to figure it out and I observed that if the namespaces in question are listed in exclude-result-prefixes list in xsl, then while testing the XSL in jDeveloper duplicate namespaces occur in the target and if I remove the namespace identifiers from the exclude-result-prefixes list then in jDeveloper testing the target correctly has only a single namespace declaration at the root node.
But, when I deployed the same to server and tested there, again the same problem.

Increase the trace level of AFW components to "info" with the Log Configurator J2EE service using VisualAdmin.
When the error happens again, crawl into the most recent DefaultTrace, either by opening the file or by using the more confortable NetWeaver Administrator log viewer (defaulttrace), reachable via browser at http://xiboxhostname:5<sysnr>00/nwa

Out of memory error when writing large file

I have the piece of code below which works fine for writing small files, but when it encounters much larger files (>80M), the jvm throws an out of memory error.
I believe it has something to do with the Stream classes. If I were to replace my PrintStream reference with the System.out object (which is commented out below), then it runs fine.
Anyone else encountered this before?
     print = new PrintStream(new FileOutputStream(new File(a_persistDir, getCacheFilename()),
                                                            false));
//      print = System.out;
          for(Iterator strings = m_lookupTable.keySet().iterator(); strings.hasNext(); ) {
               StringBuffer sb = new StringBuffer();
               String string = (String) strings.next();
               String id = string;
               sb.append(string).append(KEY_VALUE_SEPARATOR);
               Collection ids = (Collection) m_lookupTable.get(id);
               for(Iterator idsIter = ids.iterator(); idsIter.hasNext();) {
                    IBlockingResult blockingResult = (IBlockingResult) idsIter.next();
                    sb.append(blockingResult.getId()).append(VALUE_SEPARATOR);
               print.println(sb.toString());
               print.flush();
} catch (IOException e) {
} finally {
     if( print != null )
          print.close();
}

Yes, my first code would just print the strings as I got them. But it was running out of memory then as well. I thought of constructing a StringBuffer first because I was afraid that the PrintStream wasn't allocating the memory correctly.
I've also tried flushing the PrintStream after every line is written but I still run into trouble.

How to change value of ${eol} from \n to \r\n, writing by File Adapter

Hi All,
How to change value of ${eol} from \n to \r\n, while writing file through File Adapter.
As my file is being created in Linux environment, so for new line separater, \n is used. I mounted this file directory to windows System.
As Windows requires \r\n for new line seperator. So I need to change value of ${eol} in the Schema created for file writing.
Can any one provide help regarding this.
Thanks in advance

Hi,
When an XML payload is written to a file \n would be used as the default line separator regardless of if its windows or linux, as per the XML specification http://www.w3.org/TR/REC-xml/#sec-line-ends.
As such, one need not worry about the line separators because, the XML file would eventually be processed by a parser which usually would be able to understand both line endings (as they are whitespace characters as far as the parser is concerned).
If you want to convert the line terminators (for readability etc), 10.1.3.4 has a new feature - in the XML schema definition for the file adapter payload, add these two top level directives to the schema element:
xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"
nxsd:normalizeLineTerminators="false"

Error when configuring Sender File Adapter (XI 7.0)

Hi all,
After i had configured my Sender File Adapter of Communication Channel 'CC_SEND_MATERIAL_FILE', an error message for this Communication Channel (in Runtime WorkBench/Component Monitoring/Adapter Engine/Communication Channel Monitoring) occurred as below:
Error: com.sap.aii.af.ra.ms.api.DeliveryException: java.net.MalformedURLException: unknown protocol: dest
I think that all configurations for this Sender File Adapter are correct. But i don't know where is protocol "dest" and how can i correct this protocol.
Could anyone please help me to resolve this problem?
Thanks for all in advance,
Vinh Vo

Hi Sarvesh,
Yes, i have configured the source file with the path in the AL11. I think all an other configurations are also OK. But i don't know what is protocol 'dest'.
Anybody can explain and help me, please!

Duplicate message handling in the sender file adapter

Hi,
I enabled duplicate file handling check in the sender file adapter so that whenever there is a duplicate file it should send me an alert also it should disable the channel so that i do not get that duplicate file alert message again and again.
My question is will it activate the channel again as soon as a new file arrives or do i need to manually do that.
Michal's PI tips: Duplicate handling in file adapter - 7.31

Hi Hema,
You will have to activate the channel manually. The idea behind the 'disable' functionality is to avoid further file processing through that channel which can only start once the channel is activated again manually.

Security issues when using the file adapter

I want to use the file adapter, and in the documentation it states that you can use "directories" and "ftp".
I want to transfer a file secure and both of these options are not really secure.
Directory reading is not really secure when you read files from a windows share (SMB protocol).
Is it possible to make a share more secure in a windows environment?
In an ftp session everybody can steal the password. Is there a possibility to use "sftp"? Or will this be available?

Currently we dont have, but we will have it soon.

How to avoid duplicates when writing a file

Hai all,
I wrote a jsp program which generates html files dynamically taking particular keyword and category. In the same program i am also writing the links in xml file i.e page location (href). I page will call everday once. for the first time it is adding once if that page was called on second day it is adding agin those links are adding twice to that xml,even if those links are present in that xml file. but i need if the link is present in that xml file then it does not write again in that xml file for that i put the condition but is giving error.

Not equal
plese help me to solve this problem. I donot want to write second time if that link was already present in that. If link was not in that file then it has to write that link in that file.

while ( (record=dis.readLine()) != null )
   recCount++;
   r=record;
   //System.out.println(recCount + ": " + record); //compareTo
String sb=r.toString();
int l =0;
boolean b=sb.contains("http://localhost:8080/Links/debt_no to debt.html");
// l =sb.indexOf("http://www.abacapital.com/privacy/?action=print");
l =sb.indexOf("http://localhost:8080/Links/debt_no to debt.html");
System.out.println(b);I think the contains and indexOf checks should be done within the loop for each line; the way it is written above, i think the loop finishes after reading all the lines which means r always contains the last line. Which means the check is always made for the last line.

"PLS-00172: string literal too long" When Writing XML file into a Table

Hi.
I'm using DBMS_XMLStore to get a XML file into a db table. See the example below, I'm using that for my PL/SQL format. Problem is that because there're too many XML elements that I use in "xmldoc CLOB:= ...", I get "PLS-00172: string literal too long" error.
Can someone suggest a workaround?
THANKS!!!
DECLARE
insCtx DBMS_XMLStore.ctxType;
rows NUMBER;
xmldoc CLOB :=
'<ROWSET>
<ROW num="1">
<EMPNO>7369</EMPNO>
<SAL>1800</SAL>
<HIREDATE>27-AUG-1996</HIREDATE>
</ROW>
<ROW>
<EMPNO>2290</EMPNO>
<SAL>2000</SAL>
<HIREDATE>31-DEC-1992</HIREDATE>
</ROW>
</ROWSET>';
BEGIN
insCtx := DBMS_XMLStore.newContext('scott.emp'); -- get saved context
DBMS_XMLStore.clearUpdateColumnList(insCtx); -- clear the update settings
-- set the columns to be updated as a list of values
DBMS_XMLStore.setUpdateColumn(insCtx,'EMPNO');
DBMS_XMLStore.setUpdateColumn(insCtx,'SAL');
DBMS_XMLStore.setUpdatecolumn(insCtx,'HIREDATE');
-- Now insert the doc.
-- This will only insert into EMPNO, SAL and HIREDATE columns
rows := DBMS_XMLStore.insertXML(insCtx, xmlDoc);
-- Close the context
DBMS_XMLStore.closeContext(insCtx);
END;
/

You ask where am getting the XML doc. Well, am not
getting the doc itself.I either don't understand or I disagree. In your sample code, you're certainly creating an XML document-- your local variable "xmldoc" is an XML document.
DBMS_XMLSTORE package needs
to know the canonical format and that's what I
hardcoded. Again, I either don't understand or I disagree... DBMS_XMLStore more or less assumes the format of the XML document itself-- there's a ROWSET tag, a ROW tag, and a then whatever column tags you'd like. You can override what tag identifies a row, but the rest is pretty much assumed. Your calls to setUpdateColumn identifies what subset of column tags in the XML document you're interested in.
Later in code I use
DBMS_XMLStore.setUpdateColumn to specify which
columns are to be inserted.Agreed.
xmldoc CLOB :=
'<ROWSET>
<ROW num="1">
<KEY_OLD> Smoker </KEY_OLD>
<KEY_NEW> 3 </KEY_NEW>
<TRANSFORM> Specified </TRANSFORM>
<KEY_OLD> Smoker </KEY_OLD>
<VALUEOLD> -1 </VALUEOLD>
EW> -1 </VALUENEW>
<DESCRIPTION> NA </DESCRIPTION>
</ROW>
ROWSET>';This is your XML document. You almost certainly want to be reading this from the file system and/or have it passed in from another procedure. If you hard-code the XML document, you're limited to a 32k string literal, which is almost certainly causing the error you were reporting initially.
As am writing this I'm realizing that I'm doing this
wrong, because I do need to read the XML file from
the filesystem (but insert the columns
selectively)...What I need to come up with is a proc
that would grab the XML file and do inserts into a
relational table. The XML file will change in the
future and that means that all my 'canonical format'
code will be broken. How do I deal with anticipated
change? Do I need to define/create an XML schema in
10g if am just inserting into one relat. table from
one XML file?What does "The XML file will change in the future" mean? Are you saying that the structure of the XML document will change? Or that the data in the XML document would change? Your code should only need to change if the structure of the document changes, which should be exceptionally uncommon and would only be an issue if you're adding another column that you want to work with, which would necessitate code changes.
I found an article where the issue of changing XML
file is dealt by using a XSL file (that's where I'd
define the 'canonical format'), but am having a
problem with creating one, because the source XML is
screwed up in terms of the format:
it's not <x> blah </x>
<x2> blah </x2>
x2="blah" x3="blah> ...etc
Can you point me in the right direction, please?You can certainly use something like the DBMS_XSLProcessor package to transform whatever XML document you have into an XML document in an appropriate format for the XMLStore package and pass that transformed XML document into something like your sample procedure rather than defining the xmldoc local variable with a hard-coded document. Of course, you'd need to write appropriate XSL code to do the actual transform.

Page fault in nipalk.sys when writing large file , system crashes

When reading from VXI 2211 and writing to a file the system crashes with a page fault error in nipalk.sys. I tried loading new drivers for VISA, VXI, even DAQ which I don't use. Where does nipalk.sys come from??

This is the low level device driver used by all NI hardware device
drivers. PAL stands most probably for Platform Abstraction Layer and
what that means it is providing an uniform device driver API for
managing memory, IO addresses, DMA channels and Interrupts. Most
probably this NIPAL device driver API is almost the same on all
platforms NI develops modern hardware drivers for. This allows easier
porting of device drivers to new hardware as the big work for porting a
hardware driver is about porting this NIPAL device driver.
I
would not think that disk writing is the real culprit here, but it may
trigger a problem occuring earlier during VXI access.

Duplicate Records error when processing transaction file....BPC 7.0

Hi All,
I have a situation. I am using BPC NW 7.0 and I have updated my dimension files. When I try to validate my transaction file every single record is validated successfully. But when I try to import the flat file into my application, I am getting a lot of dupplication records error and these are my questions.
1. Will we get duplicate records in transaction files?
2. Even if there are duplication, since it is a cube it should summarize not display that as a error and reject records?
3. Is there something I can do to accept duplicates (I have checked the Replace option in the data package, to overwrite the simillar records, but it is only for account, category and entity only.
5. In mycase I see identical values in all my dimension and the $value is the only difference. Why is it not summing up.
Your quickest reply is much appreciated.
Thanks,
Alex.

Hi,
I have the same problem.
In my case the file that I want to upload has different row that differ for the nature column. In the conversion file I map different nature to one internal nature.
ES: cost1 --> cost
cost2 --> cost
cost3 --> cost
In my desire was that in BPC the nature cost assume the result cost = cost1 + cost2 + cost3.
The result is that only the first record is uploaded and all other recorda are rejected as duplicate.
Any suggestion?

Not enough memory to complete operation when writing TDMS file.

Hello,
I am new to Labview and having a bit of trouble. I attach some code here. What I want to do is sample from a NI 9220 DAQ from 16 channels at 20kHz, while from a second NI 6009 sample from 4 channels at 1000 kHz. I want to append these together and then write to a TDMS file.
I have tried to write this code using NIDAQmx VIs but when I have it has resulted in the two DAQs not having the right timing with each other. The 6009 samples for a longer time.
I have now tried instead to use the DAQ assistant to read from the two VIs and it works in that TDMS files produced have the correct timing between the two DAQS. However, if I record for more than 2 minutes, in the end I want to end up recording for a much longer time, I have the "Not enough memory to complete operation" message appearing. This still happens even if I get rid of my charts to display the data, and also if I get rid of the NI 6009 completely and just keep the 9220 sampling at 20kHz. It happens even if I repalde my TDMS write and put a write measurement assistant in which I tell it to write a series of files that are each less than 2 minutes long.
I think it is something to do with the amount of data I am reading and is being held in memory. What can I do about this? Also, my charts display very slowly, basically evey second when the 20k are read in. However if I lower the amount of data read the charts don't display all the data points.
I attach my code, thanks for your help!

As far as your charts updating very slowly - the way your code is designed, your charts only get data when both 20K samples & 1M samples are done collecting. Have you tried setting up DAQ assistant for continuous sampling instead of 20K samples or 1M samples?
