Use Temporary File (File Receiver)

Hi All,
I have a file format in the file receiver which has a special charecter(#0) that represents the end of the file. but i wanna append more than one message to the same file. if i do so, the content would be added after the end of the file charecter (#0) there by my system which processes these files ignores the content. i think i hav to do something using the option 'Use Temporary File'. but i din't find ample info about it on help.sap.com. Can any one plz throw some light on this?
Thnx in Advance
Anil Kumar Veepuri

Hi Anil,
The functionality of temporary file is that, the receiver file adapter first collects the data of the file into a temporary file before putting it on the server.
This is generally use so that ur target system does not read the file when u are writing it on the server.
Try using File construction mode Append.
Hope this helps.

Temporary Internet Files in Java Application

Hello,
I would like to know how to use "Temporary Internet Files" in a Java application.
When I make a Java Applet that fetch some internet files and launch it from internet browsers,
the fetched files are cached in "C:\Documents and Settings\***\Application Data\Sun\Java\Deployment\cache\6.0"
as "Temporary Internet Files". However when I launch it from Applet Viewer in eclipse or use the
fetching code from a Java application, no files are cached in the directory.
Is it possible to enabling cache with a Java application?
Here is the test code I used.
final String USER_AGENT = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)" ;
String urlString = "http://www.abysse.co.jp/japan/pref/images/hokkaido4.jpg";
URL url = new URL( urlString );
URLConnection conn = url.openConnection();
conn.setDoOutput( true );
conn.setRequestProperty( "User-Agent", USER_AGENT );
DataInputStream in = new DataInputStream(conn.getInputStream());
byte[] jpgBytes = new byte[conn.getContentLength()];
in.readFully(jpgBytes);
FileOutputStream fos = new FileOutputStream("C:\\httpoutap.jpg");
fos.write(jpgBytes);
fos.flush();
fos.close();
fos = null;Edited by: mirror_j on Jan 28, 2009 12:22 AM

I would like to know what the caching feature is build in.As I said "You cannot enable it as it is not a built in feature."
This is not strictly correct. You can use LinkedHashMap for a simple cache, but its not a persisted cache so wouldn't be very useful for you.
I suggest you look at using ehcache. It free and widely used.

'Use Temporary File' in Receiver File channel

hi all,
I am facing a strange issue with receiver file channel which I am not sure if somene had already faced. I couldnt find any help from blogs..!
I have configured the Receiver File channel with Write mode as 'Use Temporary File' with a temporary file name(say tmp.xml) scheme and Empty-Message Handling set to 'Write Empty File'
When the scenario is executed, its so happening that the temporary file of 0 bytes(empty file) is being created as tmp<msgID>.xml before the actual file is being completely written. It is expected that once the Actual file is completely written, the tmp file should be deleted, but here is not the case.Thus causing both the files being present in the target location. This is not happening often though.
As the receiving application is processing all files from the target direcotry, the file is getting errored out in the target application.
I think the 'Write Empty File' has nothing to do with this as the option 'Write Empty File' is for empty payloads resulting from the message mapping.
Please correct me if am wrong and also provide me the inputs on my issue. Am on PI7.0
thanks in advance,

Hi Tilak,
this is real time interface
real time by using a file... that's a non-sens according to me. You should use a non physical solution (web service, JMS, JDBC, etc...) but a not a file. well... Anyway, you can image that the receiver application schedule the folder every 30s or every 1min, that's almost a real time. Real time is mainly a conceptual view (only synchronous exchange needs really real time). Morevoer, if you really wanted a real time, you should not add a tool like PI (or other) between your source and your target system, the more we have systems, the less it's efficient (in term of delay and response time!).
Even if we propose that the receiver application should have a condition to its script to avoid picking the tmp*.xml files, after a period of time there would be a chance that the *tmp files may increase in number..
No ! coz if my theory is good, if your receiver application does not pick-up tmp.xml, that means this file is not currently treated and so PI is authorized to delete it. So no increase of tmp.xml files in this folder.
Another solution: to create the target file without option "temporary", but to create it in another folder than this one scheduled by your receiver application, and use an OS command AFTER processing, in your receiver CC, which move the created file from the "temp" folder to the target folder.

When to use "Use Temporary File" in receiver FTP adapter

Hi Experts,
I have nerver used "Use Temprary File" as the "Write Mode" in receiver ftp adapter.
I want to knwo under what kind of requirment we should use this option?
Thanks in advance.
Best Regards,

Hi Aditya
Usually it's advisable to use "use temporary file" as write mode when you want to avoid your file to be picked up by receiver while PI channel is still writing it.
Obviously larger the file, more chances you have that this issue could occur.
If you select the "use temporary file", XI will write the content to a temporary file with another name of your choice and only once writing has finished it will rename it to the actual name setup in the "file name scheme".

Use temporary file in FTP receiver adapter

Hi guys,
I'm not getting the purpose of "use temporary file" in FTP receiver adapter. Can you describe any situation, where this should be used?
What is the location of this temporary file?
Is it deleted after "normal" file is created?
Thanks a lot,
Olian

> I'm not getting the purpose of "use temporary file" in FTP receiver adapter. Can you describe any situation, where this should be used?
Some times when you create the file on your target dir then if there is another application looking for same file is quite faster to pick the file before it is complety written on target dir then in this situation using temporary file option is very helpful. What it does, it simply creates the file first by using temporary name once all bytes or bits has been transfered then it creates the original name and the temp file get deleted.
> What is the location of this temporary file?
Same location, where your original file is suppose to be written.
> Is it deleted after "normal" file is created?
Yes.

Location/directory used by JRE, for saving the temporary Internet files

Hello sir,
I am working on a project( in JavaFX ) which takes the URL of a streaming FLV video( eg: http://sun.edgeboss.net/download/sun/media/1460825906/1460825906_11810873001_09c01923-00.flv ) as input and plays it in Media Player component.
I have successfully played the streaming video, by taking the aid of sample project, Media Box( http://javafx.com/samples/MediaBox/ ).
Now I am interested in knowing the location/directory, where these temporary Internet files will be downloaded to. Please let me know, the location/directory used by JRE( on both Windows and Linux ) for saving the temporary Internet files. Also let me know, if there is any possibility of changing that location/directory.
Thanks for any help, in advance.

You should avoid posting the same message multiple times...
By definition, streaming is supposed to play the received movie data on the fly, without intermediary file. Now, it depends on implementation, if that's real streaming, etc., so in practice there might be a temp file, or not.
But this temp location will be, obviously, highly dependent on the current system (even between WinXP and Win7, for example). You can find the answer experimentally, eg. on Windows by using Sysinternals' Process Monitor application (did that to find out where Storage files go), but it is brittle.
I doubt there is (an official) way to know that from within the JavaFX application...

I am using Adobe Acrobat 9 Standard version in Windows 8.1 and when I try to create a .pdf file, I receive the following error message "Acrobat could not open "file name.log" because it is either not a supported file type or because the file has been damaged. To create a PDF document, go to the source application then print the document to .pdf" I am going to the source application and printing the document to .pdf yet it's saving the file as a .log file. After reinstalling the software, I initially didn't encounter this problem but on my second and third attempts to convert files to .pdf format, this error message reappeared. How do I resolve this problem?

I have a similar problem which i did not have before...and it exists only in some powerpoint files which i want to print as a pdf file...and i get the same message as above.
the log says the bellow details...what's the problem and how can i resolve it? thanks.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

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.
http://help.sap.com/saphelp_nw2004s/helpdata/en/4b/a20c4cfea96b498b1e1af3f32f0670/frameset.htm
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.

Did you check if the Firefox file is in that location?
If it isn't there then do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
If the file is there then do a malware check with some malware scan programs.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of the database before doing a scan.<br />

File adapter @ receiver end using fieldFixedLengths

Hi ,
I am using file adapter @ receiver end using content conversion.
Using field separator as 'nl'.
When i open file in Hex mode it's showing the field separator as 2 Cariage returns(CR) & 1 line feed(LF).
But the requirement is only 1 CR n 1 LF . I tried giving like this,
Datarow.fieldFixedLengths : 15,15,15,15,10,10,10,10
Datarow.endSeparator : '0x0A' or '0x0D'
but da result is same...2 CR n 1 LF..
even if i dont give endseparator then also same thing is happening..
regards,
Kishore

Hi Kishore,
Try using fieldseparator directly, instead of working around with fixedFieldlength.
cheers,

GPO Disk space to use (8-1024 MB) for Temporary Internet Files and History Settings

I am trying to create a GPO that will allow me to specify 1024 (MB) for Disk space to use to go to IE, the General Tab, Settings,

User configuration, windows settings, Internet Explorer Maintenance, (use preferred mode) Corporate Settings, Temporary Internet Files, (I select for the settings) Every visit to the page
Set amount of disk space to use (in MB)
It maxes out at 256 MB - I tried to manually adjust this but it does not work....
I tried to adjust some equivalent registry entries for under content, cachelimit (decimal) 102400 but it did not work.
Any ideas how to adjust it so that it will allow to use 1024 MB? I tried just about everything....

Why does FF use the IE Temporary Internet Files directory?

I have used Firefox exclusively as my browser for the past 6 months. Recently, I checked my "Temporary Internet Files" folder, where IE stores visited pages, and found it full and up to date, even though I had deleted everything in it when I started using FF. Why is Firefox storing data in here? Please note: On my computer, I have set up the "Temporary Internet Files" as the IE cach folder...IT IS NOT THE FF CACHE FOLDER. Thanks for any help.
