In LabVIEW applicatio, I want to write some data in a MongoDB.
I found the C# Driver for LabVIEW under the following link: https://decibel.ni.com/content/docs/DOC-41766
When i open the LV-project and try to run an example, i get many errors.
Mainly the class of the driver can´t include / load.
.NET is installed on the system.
Has someone any idea or can give instructions to get the driver running in LabVIEW?
Did you create a LabVIEW.exe.config file (there's an example in the MongoDB-driver package) and store it in the same folder as LabVIEW.exe and relaunch? That did the job for me!

Here is my problem. I need to use the functions of mongodb defined in kettle source code. As in kettle-5.3 transformation steps, it supports mongodb input and output(in big data). I download the 5.3 version from github, github link. But I can not find the source file of mongodb in the path of "\pentaho-kettle-5.3\engine\src\org\pentaho\di\trans\steps\". Actually, all the steps can be found here.
Could anyone help me find the mongodb files?
And my target is to customize the mongodb input step by using Metadata Injection to rewrite the .ktr file. In this way, users can give the parameters(define the name of the data in mongodb) from outside, such as a web page. Is there any wrong with this idea?
Any suggestion is appreciated!! Thanks!!!
I'm not sure, but I think the sources you need can be found in here:
https://github.com/pentaho/pentaho-mongodb-plugin
The mongo DB steps are a separate plugin, not included in Kettle core.
How do we attach a sql query such as join query to an existing gdb process in eclipse? Whenever I try to fork the given process using debug configurations in eclipse, which is a shared library , I am getting the following error:
No source available for "__kernel_vsyscall() at 0xb729c424"
Also, whenever I set break points in a specific program in eclipse, control goes to main.c and finally the process never comes back to the actual program.
Is there any way that the process be constrained only to my specific program?

Um, what?
Are you attempting to debug a PostgreSQL server backend? If so, see the PostgreSQL wiki page that provides lots of details on the topic.

What is a shared library? Eclipse isn't. PostgreSQL isn't. So what's the shared library here?
Are you trying to debug a PostgreSQL extension? If so, see the above link for details on attaching to a PostgreSQL server backend.
No source available for "__kernel_vsyscall() at 0xb729c424"
That's normal. It's just telling you that there's no source code on record for the __kernel_vsyscall call that's the entrypoint into syscalls in linux-gate.so via glibc when using sysenter.
The stack below it should be more informative. Get a backtrace, then look at the lower stack frames.

Your "also" is really a separate question, and it's pretty hard to answer it usefully with the total lack of information provided. Try posting a new, more detailed question on just that topic. Specify how you compiled the program, set it up for debugging, how you're running it, where you're trying to set breakpoints, etc.
I have been trying to use gprof with MongoDB to do profiling. Having the corresponding build file to mongod, which is in Scons, modified to include the proper linker and compiler flags (based on the hints at How to build-in gprof support to a program built with SCons?), I am still unable to see the expected output file (gmon.out). I have made the same changes on a toy project and it's working just fine. I was wondering if there is any change that I can make on MongoDB to make it work with gprof. If there is no hope in using these two together, I'd appreciate any suggestions on other tools that I can use to get similar profiling numbers.
Hi Markloggers out there,
I am working now a coupe of months with Marklogic, developping xquery, modules, applications on the ML app server etc etc. I use eclipse a lot, I have XQDT up and running for several marklogic servers. We use the console also.
What I miss is a debug functionality... in Eclispe with XQDT I cannot get the debug function working?
What I need is a nice and clean way to quickly test and develop modelules and functions...
This is my basic lib from the ML example documentation:
xquery version "1.0-ml";
module namespace lib = 'http://www.example.com/lib';
declare function lib:user()
{
xdmp:get-current-user()
};
I have this is my XQDT project in eclipse, I have setup a marklogic XDBC server locally and it works ok.
Now I want to use the above module from a file again in the XQDT project in eclipse. But without going to steps of uploading the module to the db etc etc...:
(: XQuery main module :)
import module namespace lib = 'http://www.example.com/lib' at 'lib.xq';
lib:user()
Gives:
XDMP-MODNOTFOUND: (err:XQST0059) Module /lib.xq not found
Question 1: Is there a way to find the module without putting it in a module root? In the docs it says from a XQDT project I could source a module but I cannot get it to work...
Question 2: I can execute arbitrary xquery to the local Marklogic server but if I set a debug flag anywhere in a xgy file in the XQDT project and press the debug button I get a popup saying "The Debug Engine is not properly configured". Can anyone explain to me if it is possible to use the debug option in eclipse XQDT with Marklogic 7 ?
Regards,
hugo
It's best to limit yourself to one question per SO post. After all you can only accept one answer.

That's a problem. You can evaluate an ad-hoc query directly. But if it references a library module, that library module needs to be available to the server. You're going to have to copy it to the server sooner or later anyhow, so do it sooner. I don't use an IDE myself, but can't you set it up to do that for you?
Question 1: Is there a way to find the module without putting it in a module root?
Not in the broadest sense of "module root", no. The docs at https://docs.marklogic.com/guide/app-dev/import_modules talk about how this works. Somehow or other, you need to make the library module available to MarkLogic.
I can't address your last question. I don't use an IDE, and even if I did I probably wouldn't use a debugger. Instead I xdmp:log messages to ErrorLog.txt, and occasionally I'll plant an breakpoint-like error() call in my code.
I have downloaded and started the community version of SFSx2. I read everything on their documentation page:
http://docs2x.smartfoxserver.com/DevelopmentBasics/introduction
Which unfortunately only talks about flash client side code. Nothing about the corresponding server side code, nor about html5 client side which I need.
I downloaded the HTML5 examples, which took me a long time to find (they are here: http://www.smartfoxserver.com/download/get/140 )
None of the examples work, as they can't connect to the server. Presumably, this is because the examples only supply client side code. There are no instructions supplied on how to install or run the examples.
I can find no mention on the smartfox documenation on the following:
1) what language is used on the server side. One assumes its java.
2) how does one deploy java code to the smartfox server? I cant find any mention of this in the docs.
3) how does one find and install the server part of the client side examples (which are Tris, GameLobby, BuddyMessenger, AdvancedChat).
I applied to be allowed to post on the smartfoxserver forums, but no reply yet.
I also found it hard so I share what I've found out.
The server extensions are written in Java. I used Eclipse JUNO to write my code.
You can download Eclipse here. http://www.eclipse.org/downloads/
You export the extension in jar format from eclipse into you extension path. The name of your file has to end in 'extension' eg MyFirstExtension.jar otherwise sfs2x wont recognize it. Your extension path will be something like this: C:\Program Files\SmartFoxServer2X\SFS2X\extensions\MyFirstExtension\MyFirstExtension.jar if your working in windows.
You will find docs on JAVA API here. http://docs2x.smartfoxserver.com/api-docs/javadoc/server/
This is a link to the basic example code: http://www.smartfoxserver.com/download/get/120
Unzip the content into the [SFS2X_install_folder]/SFS2X/www/root/examples folder, overwriting the existing file. Run the index.html file, then navigate to another index.html to open the example. Run the sfs2x-standalone.exe first of course(see below). If you followed the 'server configuration tutorial' on smartfox website and changed the server ports, the examples wont work. Leave the ports alone until you start to understand the server.
This is a link to the flash example code: http://www.smartfoxserver.com/download/get/108
You will find the example code for apps mentioned above. They are written in Adobe Flash Builder and Java extensions. I don't know if there is any code for HTML5 but the Java server code and AS3 is there.
I also found that using the standalone server was the way to go rather than using SFS2x as a service. c:\program files\smartfoxserver2x\sfs2x\sfs2x-standalone.exe. Using the exe gives you the command prompt window. You can use the window for debugging and see the state of the server when it starts.
Most of the examples should work without creating extensions but to create an extension out of source examples:
Create and setup a new project in your Java IDE. You will have already set up a workspace.
Copy the content of the /source/server/src folder to your project's source folder.
Add SFS2X Libraries. Go to properties of the project -> Select Java Build Path -> Click Library Tab -> Add external jar. Add 'sfs2x.jar' and 'sfs2x-core.jar' from C:\Program Files\SmartFoxServer2X\SFS2X\lib folder. To create the extension, export jar file to extension path. Restart server.
Another problem I had was the Java Version I was using. I had to use Java1.6 with my version of sfs2x when writing extensions. This was trial and error as there was no documentation. There may be a newer version out now.
I had to copy all the server source into eclipse to try and understand how things were done. It was a way of having all the code in one place. There was a lot of trial and error as getting help is hard. I eventually accomplished what I set out to achieve. Good Luck.
SmartFox Server is easy to use even with extension. documentation Give try to Nuggeta solution for game development too. No extension needed at first. This is optionnal.
