How to load configuration files with to TestStand

Hello,
I need an expert advise on setting up Teststand environment. I am developing a generic tester that will eventually support multiple product lines. The PXI equipment is common but the Pin assignment will change from product to another. So, I was thinking to have a configuration file (xml, excel, .csv...etc) that defines each product line. The configuration file will contain all the pin routing, like which pin is connected to which NI Card channel and fault insertion unit. My thought was to load this configuration file to the Teststand environment before starting a series of tests. I had in mind using XML files and use a labview parser to extract the data and write it to Teststand variables. My question is:
Is this the best practice for this approach ? Is there a better method ? Can I load data into Teststand first and hold the data in Teststand while testing a bunch of UUTs. I do not want load this file at the beginning of every Test, just once when opening Teststand.
I appreciate any advise on this.
Thanks,
Ayman

I'm using .ini file with configuration information and a startup sequence what read this file, configure the system and then run selected tests. Selected tests list is in the .ini file as well. Configuration info is passed to subsequences as a parameter or "propagate local".
I disagree with the idea of creating a separate sequence for each product, this solution is not scalable.

How to load a file with out specifying its absolute location

Hi,
I'm having some config files in a specific location. I'm setting that folder path to the CLASSPATH and trying access those file just by giving its name.
For eg: contents are in e:\config folder
I set e:\config to CLASSPATH
and trying to load the file which is in the above said folder.
using getResourceAsStream(filename).
The above approach is working in certain cases, but not working when i try to do in a class which under a big package structure.
Can someone help me out, the reason for this unexpected behaviour.
Please do suggest me, if u know some work-around for this problem.
Thnaks in advance,
Chandrasekhar

Hi,
Thank you. I tried by adding a forward slash, it started working.
But I still have one doubt, when the program is within the package structure, then we have to give forward slash, where as if the program doesn't have any pkg structure we have to give only the file name without prefixing the slash.
Any idea, why is it so ??
Is it bcz, that getOutputAsStream() will prepend the package names, if forward slash is not given. Even if this is true, why providing a forward slash in a program with no packages doesn't work ?

How to call sql loader ctrl file with in the pl/sql procedure

Hi Friends,
I am doing a project related with the transferring data using queues. In the queue , I will get a tab delimited data in the form of CLOB variable/message. I do want to store that dat in the oracle table.
When updating data into the table ,
1. Don't want to write that data into a file.( Want to access directly after dequeueing from the specfic queue).
2. As the data is in tab delimited form, I want to use sql loader concept.
How do I call the sql loader ctrl file with in my pl/sql procedure. When I searched , most of the forums recommending external procedure or Java program.
Please Guide me on this issue. my preferrence is pl sql, But don't know about external procedure . If no other way , I will try Java.
I am using oracle 9.2.0.8.0.
Thanks in advance,
Vimal..

Neither SQL*Loader nor external tables are designed to read data from a CLOB stored in the database. They both work on files stored on the file system. If you don't want the data to be written to a file, you're going to have to roll your own parsing code. This is certainly possible. But it is going to be far less efficient than either SQL*Loader or external tables. And it's likely to involve quite a bit more code.
The simplest possible thing that could work would be to use something like Tom Kyte's string tokenization package to read a line from the CLOB, break it into the component pieces, and then store the different tokens in a meaningful collection (i.e. an object type or a record type that corresponds to the table definition). Of course, you'll need to handle things like converting strings to numbers or dates, rejecting rows, writing log files, etc.

Failed to load configuration file for the workflow

There are two of us who have full control on our Sharepoint 2013 site. I'm able to create workflows and publish them fine. The other user is able to create workflows, but he gets an error when trying to run them. I tried opening his workflow and got
the error "Failed to load configuration file for the workflow."
Any ideas?

Hi Carltonw1,
Based on your description, I recommend to verify the things below:
Clear the SharePoint Designer cache and then open the workflow.
Ask the user to open the workflow in SharePoint Designer and check if the workflow contains error.
Ask the user to create the same workflow and associated with another list to see how it works.
Check the ULS log for more detailed error message.
To reproduce this issue, could you please provide the detailed steps in the workflow for further research?
Thanks,
Victoria

Uregnt - How to Load Flat File into BW-BPS using Web Browser

Hello,
We have followed the 'How to Load Flat File into BW-BPS using Web Browser' guide to build BSP web front-end to upload flat file. Everything works great but we have a requirement to populate the Planning Area Variables based on BSP drop down list with values. Does anyone know how to do this? We have the BSP coded with drop down list all we need to do now is populate variables. We can populate the variables through the planning level (hardcoded) but we need to populate them through the web interface.
Thanks,
Gary

Hello Gary,
We have acheived the desired result by not too a clean method but it works for us.
What we have done is, we have the link to load file in a page where the variables can be input. The user would then have the option to choose the link to load a file for the layout in that page.
By entering the variable values in the page, we are able to read the variables for the file input directly in the load program.
Maybe this approach might help.

How to load text files in GUI

plz tell me .. how to load and compare two text files using file popup's . example file i have attached..
Attachments:
testW_FF.txt ‏2 KB

I don't understand whether your question is on how to load text files or how to show them on a panel or how to compare them... or all aspects together!
The first operation (loading the file) can be accomplished with functions included in the Formatting and I/O Library like OpenFile, ReadFile and so on; with a file like yours even FileToArray could be an option.
How to show the data on screen is heavily dependent on what you intend to do with them: data can be shown in textboxes, listboxes, tables or graphs so... what do you want to do?
The same applies with comparison: without additional details is difficult to give you the proper hint.

How to delete the file with space in name

Hi
I want to delete the file "test ex.txt" file.
i run the following command in command prompt.i can delete the file successfully.
/bin/rm -f /mnt/"test ex.txt"
I want to run the command from java.So i am using the following code
String cmd = "/bin/rm -f /mnt/\"test ex.txt\"";
Runtime rt = Runtime.getRuntime();
process = rt.exec(cmd);
The file was not deleted.
How to delete the file with space in name?
Help me

Use the form of exec that takes an array of command + args.
arr[0] = "/bin/rm"
arr[1] = "-f"
arr[2] = "/home/me/some directory with spaces";Or use ProcessBuilder, which is the preferred replacement for Runtime.exec, and which Runtime.exec calls.

How to load flat file in existing Architecture.

Hi everyone!
There is an existing architecture that I have to upload data into. There is a cube on top, followed below by an ODS and its update rules to the cube, followed below by an Infosource and its corresponding update rule to the ODS above it, followed below by a datasource (it says PC FILES(PC_FILE)) and its accompanying transfer rules to the infosource....
There is nothing in the ODS... No data. The Datasource says emmulated 3.x Datasource... (What does this mean?)
What I want to do is upload data via a flat file... Good BI Masters, how do I do this? How do I create a "dummy file" for upload? What are the specific sequence of steps that I need to do to load this flat file data?
Thank thank you so much!

I'm not sure what you are asking - is it how to load a file all the way to cube in 7.0?
From the architecture desc you have given, you havent migrated ur dataflow to new 7.0 dataflow, as you still have the update rules and transfer rules. So though ur system is 7.0, ur backend is still on 3.x, so the way you load a file is the same when your system was 3.x(before upgrade)
Or - are you asking the steps to load the file to a cube - no matter which environment you are in (3.x or 7.0)? if so, let us know .. and do a search on the forum for steps to load flatfile

Hi Dilpreet,
reading wav files is easy using the functions from the sounds palette...
For your other tasks you could use a seperate toolkit or do some programming on your own!

How to load flat file in BPS through Web-debugging

Hi,
We are working on flat file upload in BPS thru guide 'How to load flat file in BPS through Web'. Can some one guide on how to debug the function modules used while uploading the data.
We have set up the break point in the function modules and also in the BSP page. But when trying to debug while uploading, it is not going to the break point which was set.
Could you assist in setting up the break point.

Hi,
I have put an external break-point.
I have hard coded it in the coding of the function module itself.
The code is perfectly working. But, when I want to check for the values of the variables in the F.M during runtime, the break-point is not triggering. Any ideas??

How to create pdf files with text field data

how to create pdf files with text field data

That looks like it should work, but it doesn't.
I opened the PDF I had created from Word in Acrobat (X Pro). Went to File > Properties. Selected "Change Settings". I then enabled "Restrict editing...", set a password, set "Printing Allowed" to "none", "Changes Allowed" to "none", and ensured that "Enable copying of text..." was disabled.
I saved the PDF file, closed Acrobat, opened the PDF in Reader, and I was still able to select text and graphical objects.
I reopened the PDF in Acrobat, and the document summart still shows everything as allowed. When I click on "show details" (from File > Properties) it shows the correct settings.
Any ideas?
