Create .txt empty file After Message Processing Command Line Linux command

Hi All,
An empty .txt file has to be created in FTP location(FTP loc c:\xyz\Customer20082910.txt) only after the .dat file has been created(FTP loc c:\xyz\Customer20082910.dat)
Note:.dat has the actual data and .txt is an empty file and is created only after .dat is created
I know that .txt empty file can be created using the After Message Processing Command Line...
But confused which command to be given such that it will be created in the FTP location(c:\xyz\Customer20082910.txt)
Can any one please give the Linux command for it...
Regards,
Sridhar

Hi Aamir,
Thanks for the suggestion, I will ask my client to create a shell script at FTP server...
And one more question,
This is reverse side , now the .dat file is to be picked only if .txt exists at the FTP server (scenario File > XI>SAP) (earlier was SAP>XI>File)..
So please can you suggest for this also...
How can i check for the .txt and pick corresponding .dat file...
i had posted question long back
Need to pick .TXT file only if .CTL file is available
Regards,
Sridhar

Create a trigger file after successfully processing of a regular file?

Hi,
I have 10 differet proxy-tofile scenario interfaces going to one target system (10 different transcational data sets). For each interafce after creating the file (fixed file name file1.txt), PI has to create/append a file called "trigger file" which has different structure with fine name, file creation date/time etc. and kind of file (all or delta) which comes from proxy.
So if file1.txt (all) has created, after that PI has to create "trigger file" with:
file1.txt 20110106 all
So if file2.txt (changes), another interface with different transaction, is created, we need to append "trigger file" with:
file1.txt 20110106 all
file2.txt 20110106 delta
Can I do this scenario without BPM, in Integrated Configiration, we are in PI 7.1 EHP1.
Regards,
N@v!n

Hi All,
Let me try to put the question differently for the same scenario. I have completed dev with two message mappings, two operation mappings (one for regular file and one for tigger file). In ID, I am using the Integrated Configuration (with multiple receivers; here I created 2 communication components, one for regular file, another one for trigger file). This scenario works fine, creates regular file and trigger file. Only thing is it creates trigger file even regular file fails, we dont want to create a trigger file when the regular file creation fails..... since we have lof of scenario like this, we want to use integrated configuration only......I have tried to use one operation mapping (with multiple message mappings with in it), but looks like Integrated Configuration doesn't support this.
So if I have one operation mapping with 2 message mappings in it, does operation mapping fail when one of the message mapping fails? At the end all we wanted to do create a file when ever the regular creats successfully. Pleae help me with the design. Let me know if you need more info.
Thank You,

How to Run Operating System Command Before/After Message Processing SAP PI

Hi,
We are trying to execute multiple commands via "Operating System Command Before/After Message Processing".
When we use single command say for example cp or mv (copy or move) the commands get executed fine.
eg: cp %F /var/opt/data/outbound/Test/Dummy.txt
/this works fine/
when we club commands together or try to redirect the outputs of commands, none of the commands get executed.
eg:
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
or
wc -l %F > /var/opt/data/outbound/Test/Dummy.txt
Is it possible to execute multiple commands or redirect the output of commands without using a shell script? The PI server we are working on iis hosted on UNIX environment.

Hi Harleen,
try like this
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
instead of semicolon try this
(1) &
command1 & command2
Execute Command1 and then execute Command2
(2) &&
command1 && command2
Runs the command2 only when command1 doesn't Complete successfully
(3) ||
command1 || command2
Runs the second command if the first command had an error
(4) ()
(command1 || command2) || (command3 & command4)
Defines the order in which commands are to be executed

Preflight keeps saying "Unable to save the PDF File after post processing"

I'm at a loss how to overcome this. Spent almost a whole day, together with another person, trying to fix it with no success!
I use Adobe pro CC on a PC
I usually receive pdf files from this one client who edits and formats a book in Mac Pages. Up until a few days ago I had no problems converting the client's pdfs into pdf/x3, but the last three versions of the latest file have stumped me.
Just to test, I first just tried to convert the file (33MB), unchanged, to pdf/x3 using the save as other option - message reads "the document has been saved, however, it could not be converted according to the selected standard profile: convert to PDF/X. Please use preflight with the profile "Convert to PDF/X" in order to identify those properties of the document which prevent it from being compliant to this profile"
if I then choose under Profiles - convert to PDF/X3 - it says no problems found, and appears to have saved the file. If I try to save again as a pdf/x3, just to make sure, it then tells me it's not pdf/x3 compliant
OK - so then I go back to preflight - and choose the standards function - then pdf/x3, then continue with the default colour profile. About halfway through the conversion, at the point of saving the file, I get the message "unable to save the pdf file after post processing"
So far I've had no luck figuring out what this is.
I then choose the option of "verify compliance of ppdf/x3" - message reads "pdf/x3 version key (GTS_PDFXVersion) missing", and "Trapped key not true or false"
Help!! How can I be sure the file converted / or not?

Yes I was/am aware of Preflight's inability to play nicely over cloud technologies in certain cases, especially wrt Standards technologies, this will be partially addressed in an upcoming version of Preflight without saying too much. But the same thing could theoretically have happened if the file was also located on another local network client or server. Leaving aside the argument that this may violate the Acrobat User Agreement - since purchasing the software, the user agrees to employ its functionality on a single host system and precludes host-client-based scenarios - this simply is not a supported use, meaning the user may not have expectations that it will work at all, if the applications requirements are not observed. There do exist server-solutions for Preflight files within networks, but Acrobat and by extension Acrobat Preflight is not one of those solutions, and (still) belongs in the single host-based desktop environment.
However most (99.9%) functions within Acrobat <-> acrobat.com file exchange are supported, file syncing across multiple devices will soon be supported, but Standards compliance is still admittedly a problem at this point. Some testing has been done using 3rd party cloud technologies starting with enterprise-based solutions, such as Office 365, and this will continue to ramp up to include other 3rd party products.
As for the second point, Preflight will usually change the PDF version to be complaint, are you saying that it was unable to do so in this case? It seems that this error should have popped up during the normal Preflight conversion attempt. Personally I think solving a workflow problem using the print path is a little bit of a heavy-handed approach, but if helped and the results are acceptable, then that is good. Since that path is non-existent on a Mac, as one needs to Save as Adobe PDF from the Print dialog's PDF drop-down menu, I am assuming your workflow involved file creation on a Mac, then further processing on Windows using the PDF printer. I am wondering if a simple resave/Save As... to PDF with overwrite on a Mac, or Preflighting the file using a PDF version compatibility profile before the PDF/X conversion would have helped. Since there are such a multitude of methods that a PDF can be created, there are also many ways within Acrobat that a user can shape the file to be compatible with the expected workflow, ie, 'many ways to skin a cat', without being morbid.

Creating an empty file using variable in script task

I created an empty file by writing a code in script task. how can i use a variable to do the same job.
System.IO.File.Create(@"C:\OneEmptyTextFile.txt");

Hi SyedF,
Just as you said, we should refer to the code below to create an empty file in the specified path using System.IO.File.Create:
System.IO.File.Create(Path)
If we want to use a variable named FilePath to control the path of the created file, please refer to the following code:
Dim Path As String
Path = Dts.Variables("FilePath").Value
System.IO.File.Create(Path)

Create an Empty file

Hi,
I want to know if there's a way to create an empty file (on PC) from a FORM.
A user would suply the file name and click on a button, and a piece of code would create an empty file on the LOCAL PC.
Similar to what TOUCH does in UNIX.
Thanks in advance,
Marc.

But isn't there any oracle PKG that will create an empty file for you? Yes , there is....This is called UTL_FILE.....
With this built-in db package , PL/SQL programs can read and write operating system text files...

Empty File has to write after Message Processing in File Adapter..!!

Hi,
File to File Scenario.
Once the file is processed and placed in the receiver folder, I need to generate one empty file with the original file name but with different extension (DON). This is used to indicate that the full file is written in the folder.
Example:
Original file has to write like "Output_Final.CSV"
Empty file has to be placed like "Output_Final.DON"
Is there any way I can achieve this requirement.?
Thanks
Deepthi.

I have no clue of removing the same using Graphical mapping ..
I hope you have set the option of Write Empty File if not try this and still doesnot work
then need to look for java or ABAP mapping
chekc the below thread may help

How to generate a empty file in AL11 using ABAP and unix command

Hi Experts,
when load infopackage triggers it will search file from AL11 if file is available it will get loaded successfully. When there is no file in AL11 error while opening file (orgin A) and the load will fail. At this level i have to write a abap code using unix command to generate a empty file.
Is there any way to achieve the above requirement.
Thanks
Vara

Hi,
If i get your requirement properly then you want to create a blank file if there is no file on the application server so that your infopackage does not fail, am i correct.
If this is your requirement then this can be easily done if you use process chain to load the file via infopackage. Follow the following steps:
1. Add a ABAP program before the infopackage and check if the file is present on the server or not. Use a simple ABAP statement OPEN DATASET <FNAME>. Check the SY-SUBRC after this statement if it is not 0 then it means that the file does not exist on the application server.
2. Once you have established that the file is not present create a flat file using a code similar to the below one
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE
MESSAGE D_MSG_TEXT.
IF SY-SUBRC NE 0.
WRITE: 'File cannot be opened. Reason:', D_MSG_TEXT.
EXIT.
ENDIF.
* Transferring Data
LOOP AT INT_table.
TRANSFER INT_table-field1 TO FILENAME.
ENDLOOP.
* Closing the File
CLOSE DATASET FILENAME.
3. Add your infopackage step after this ABAP program in your process chain.
I hope this helps.

Empty file after replace

Hello
I am facing a very strange problem saving files. Find attached a quick example showing the issue.
The first time I hit "save" and choose a name for the file (numbers.txt, for example), everything works great and the file is created with my data. Nevertheless, if I save the file numbers.txt the first time and then I click on "save" again and choose the same name for the file and click YES after "The file already exists. Do you want to replace it?", the file numbers.txt is replaced, but it gets empty!!!! If I click on "save" again and choose another name (results.txt, for example), the file results.txt is created properly. If I try to replace the file results.txt I will get the same error with an empty file again.
I think that the issue has something to do with "trying to write SAME DATA TWICE in a file", even choosing to "replace" the file. If you stop running the VI, start again, and try to save replacing a file that already exists, the file will not get empty.
Thanks.

Save File - Problem.vi ‏11 KB

Dear Dan07,
After you are done writing to the file, you should finish the whole operation with closing the file. Also, your original code writes the same set of random nubers to the file all the time. If you place the random nuber generation code inside your while loop, it will run every time you press the save button and it will generate a new set of random numbers. Please see the attached snippet for an example.
If you have any further questions, please feel free to ask!

File adapter - archiving files after successful processing & errors

Hi All
In sender file adapter, I understand that we can archive files after processing them.
After successful processing, we can archive the file, and if there are any errors, we can archive the file in a different folder (all files resulting in errors during processing are archived in a seperate folder).
Now, see this scenario.
My file is successfully picked up, processed and posted to receiving sap system thru proxy.
But, if there is any application specific error (ex: duplicate id), because of which this data cannot be processed in the receiving system, how can i move the file which is archived in successful messages folder to the folder where we archive error messages?
Is it possible?
This is required because, when there are these kind of errors with incorrect data, we want the corresponding file to be archived in the folder where erred files are archived.
Please let me know how we can achieve this.
Many Thanks
Chandra

in file sender CC, thr is option to archive and error file store also..
1)under processing mode - archive.. give the path thr..
2) To archive source files where a permanent error occurred during processing, select Archive Faulty Source Files

Cannot create a dump file for a process

Hi fellows,
I have a problem creating a dump file for an application. The application consists of C++ and C# dlls. It runs in Windows 7 64bit environment.
I constantly receive the following error:
ERROR_PARTIAL_COPY: Only part of a ReadProcessMemory or WriteProcessMemory request was completed.
and only a part of the dump is created ~ 400 MB (should be ~900 MB) although there is enough space on the disk drive.
I have tried the following options:
- Task Manager -> Create Dump File
- windbg (64bit version): .dump /a
This happens only on two machines and not on all the rest (~20 more).
All of them are equipped with Windows 7 64bit, the application is build in 64bit
Note that if I use the option /mA when calling .dump it creates the dump without errors. From the MSDN documentation:
The /mA option is equivalent to /ma except that it ignores any failure to read inaccessable memory and continues generating the minidump.
My questions are:
1) What can be the case when the memory being read is inaccessable
2) Why does it fail creating the dump file for only 2 machines

Okay, after reading the post here are the results I got:
0:013> !vprot 0x800000000

1) windbg is unable to tell me which the mapped file is
2) I have tried it several times and strangely always the problematic adress is 0x800000000 ... isn`t that weird ?

Self-created invisible system file not found via Finder's Find command

I need to see what is being created on my hard disk. To achieve that, I create a test file, call it .new in TextEdit, remove the hidden .rtf extension, and place it in one of the folders in /Library/Application Support. Then, I use Finders Find command, and ask to search This Mac, Created date: today, System files are included, File visibility Visible or Invisible, leaving the input field (for file contents or name) blank. The newly created file isn't found. I type its name into the input field, with the same result. I change its name to .new.plist . Same result. Suspecting that "System files" acutally means system files and doesn't include the Library on the top level, I place that same item in /System/Library/PodcastProducer. Same result.
Seriously, this is entirely incomprehensible. The Find command obviously doesn't do what it says it does. Could anyone tell me how to get it to, or name some alternative?
Thanks a lot.

Actually you CAN get ressults for .whatever files and folders. I created a saved search for my home folder with the criterion of "File visibility::Invisible Items" and then "None of the following are true::Name contains" DS_Store, Icon or localized. The result is a list of 65 invisible items including things such as the files /Users/francine/Library/Preferences/ByHost/.GlobalPreferences.0017f20dca84.plis t (a dot file), /Users/francine/Library/Preferences/com.freeverse.5012 (something with the invisible flag set), the dot folder /Users/francine/.fontconfig, and many others of all of these types. I thought it was interesting that lots of them were inside the ~/Library folder, even though I did NOT specify including system files.
I don't know why the original poster can't get Spotlight, using the the Command-f method, to display dot files. When I was setting my own invisible items search up I did manage to crash the Finder once, so it may be that the query for invisible items is buggy. Here's the Raw Query:
(true) && (((kMDItemFSInvisible = 1) && (!((kMDItemDisplayName = "\DS_Store"cd) || (kMDItemDisplayName = "\Icon"cd) || (kMDItemDisplayName = "\localized"cd)))))
If you go to a folder, do Command-f, then change from the default "Kind" to "Raw Query" and paste the above in as the query, you ought to get all the invisible files and folders, except the .DS_Store, Icon and localized files (of which there are likely hundreds of 'em in your home folder).

Installed 7 created dupe empty files in library...any way to easily delete?

I upgraded to the new Itunes. It initially lost my whole library settings..i.e. there were only empty files which would not play. I reset the link to the library, which is on a external drive, and consolidated the files. I now have doubled the library up so there are 3000+ files which are duplicated and dont play AND the same amount which do play. I know I can delete the duplicated empty files one by one by highlighting the exclamation point and delete. Is there a way to do this en masse? I did 600 or so and I think I have a repetitive motion disorder....
