Using the general error handler on an embedded rt target

I would like to know how the general error handler can be best employed
with Labview RT on a Compact Fieldpoint controller. Clearly no
dialogue options are valid so how can error information be accessed
remotely - is there an error log file available on the controller?

I think there are plenty of ways to handle errors with Labview RT on a Fieldpoint controller.
Usually I use the general error handler vi to catch the error and get the error message (sure, no dialog), then write the eroor message into a log file (ordinary text file created on the controller), and/or send the eroor message through TCP/IP network to the host. You can use FTP to open, read and tranfer the log file at host. Hope help.

How to add sound to the general error handler

I'm looking for an easy way to create an audible indication (a beep or something) when the general error handler displays an error message. Anyone have any suggestions??
Solved!

Hi Bill,
I thought this was an interesting idea, so I wrote up the code and posted it on the NI Community here: Simple Error Handler with Beep. If you have any cool VIs that you'd like to share, you can post them on the community as well to share them with others. Thanks!

How to monitor the alerts(error handling) in seerburger adapter?

hi,
is it like normal moniotoring for any scenario..i have to do the monitoring in seeburger adapter.
any other specific thing i have to take care to do monitoring the alerts (error handling) in seeburger adapter for AS2 and FTP adapters..
plz give other ways to monitor interfaces for seeburger adapter.
Regards
Raja

Hi Raja,
All Seeburger adapters have option of some kind of acknowledgement to be sent to the sender or any partner... u need to check the respective adapter documention....
for eg: FTP adapter can be configured for Message protocol - FTP-REPORTS
for sending various types of reports to any Business Partner,,,reports like dispatch report, transmission reports,,....etc
and for monitoring errors in XI... u can configure alerts as u normally do.....
*Reward points if useful*

How to disable the LV error handler?

I want to disable the LV error handler, im my application if an error happens i use a case structure to handle it.
how can i do?

Once you wire the error output of your function, automatic error handling is no longer relevant. That setting only matters for subVIs where you don't wire the error output.
Just take the error output and wire it to the selector terminal of the case structure. You'll get an "error" and a "no error" case. Place appropriate code in each case so it act like you want it to.

So, again with the general error

Strange. I'll open a session. Not too much in it, just an chopped up .avi and a chopped up .aiff. It exports fine, UNTIL...I make a single cut with the razor blade. Not moving anything around. Just making a single slice with it. Then, I get the 'general error' message. If I go back and undo the error, it will export fine. I've tried trashing my preferences and render files per some suggestions in other threads. Any thoughts?
mbp duo 1.83 Mac OS X (10.4.6) FCP 5.1.1

Wow...none of those are really editable codecs.
H.264 is a web delivery and HD DVD codec...not meant
for editing with. And AVIs aren't optimized for FCP
to work with (depends on the codec too...an AVI can
be one of a dozen codecs, just like MOVs). And FCP
doesn't work with .wmv files.
I'm not trying to import .wmv files into FCP. Only export.
You are having all these errors and this trouble
because of this.
I don't think so. If I take the same sessions to my dual G5, many of the problematic FCP sessions work just fine. Although, I've had similar problems on that platform as well.
The long an short of it: The original clips are avi using the techsmith encoder. I'll drag those in, make a multiclip sequence with it, bring in some audio (aif), do a bit of editing, then export with flip4mac to wmv. Weird? Yes. But, it works a fair bit of the time on my G5 setup.
The other codecs I mentioned were encounted while trying to figure out what could possibly be causing this.

I have always gone the latter route when I needed it. I usually use an action engine to keep track of the error messages. Said action engine can be used to combine and suppress errors, as well. I have posted an example below (LabVIEw 7.1). In this case, the error propagation is occurring in a task handler which is processing multiple command/data pairs. The command is set at the beginning of the task and the error handler is sprinkled liberally throughout the task code. In this particular case, the desired behavior is to continue execution on error, but log the errors.
I prefer this type of method because it gives me complete control over the error propagation. It has the down side of requiring more code and effort, but I think it is worth it. I like functionality to be explicit on my block diagrams. It makes long-term maintenance much easier.

How to resolve "You don't have permission to use the application" errors?

We've been struggling with managed preferences, specifically applications, for a few users. They have mobile home folders which live on a Mac OS X 10.6.x Snow Leopard Server AFP server, preferences which are managed (by group) on a Mac OS X 10.6.5 Snow Leopard Server Open Directory Master, and the clients are running Mac OS X 10.6.4 Snow Leopard (bound to the Open Directory Master). There are also two Mac OS X 10.6.4 Snow Leopard Server Open Directory Replicas. We always manage applications and DO NOT sign the apps when adding them in Workgroup Manager.
Essentially, key applications are unable to run due to the "You don't have permission to use the application" errors, even though they're explicitly whitelisted. (See some prior investigation over on Serverfault.) After seeing that the Mac OS X 10.6.5 Server update included the following fixes, we upgraded our Open Directory Master to 10.6.5:
* Addresses an issue that could prevent managed preferences from being applied when a user logs in on a workstation that has been idle.
* Fixes an issue that could prevent administrators from bypassing client management settings on a workstation.
This seemed to improve the situation slightly, our most important application now seems to be allowed. Occasionally, it'll give the same error, but a simple log out & back in allows it again. We have not upgraded the client workstations with the Mac OS X 10.6.5 update as it doesn't note any related fixes and we haven't fully qualified it for mass deployment.
We now have two applications that live in ~/Applications which are explicitly whitelisted (again, NOT signed), which fail with the same error, but logging out & back in does not resolve it. `sudo mcxrefresh -n 'user'` doesn't resolve the issue. In fact, `sudo /System/Library/CoreServices/ManagedClient.app/Contents/MacOS/ManagedClient -f -u `id -u 'username'`` fails with the following error:
ManagedClient- bad parameter to -u option: use format '-u 501'
Today I was able to catch the following in /var/log/system.log while attempting to run one said applications:
Dec 22 17:36:24 hostname parentalcontrolsd[43221]: -[ActivityTracker checkApp:csFlags:] [954:user] -- * Incoming app appears to be masquerading as white listed app and failed signature validation: /Users/user/Applications/FileMaker Pro 5.5/FileMaker Pro.app/Contents/MacOS/FileMaker Pro. Note: This may be a valid app of a different version than what was whitelisted (on a different volume?)
Dec 22 17:36:24 hostname [0x0-0xa42a42].com.filemaker.filemakerpro[43304]: launch of /Users/user/Applications/FileMaker Pro 5.5/FileMaker Pro.app/Contents/MacOS/FileMaker Pro was blocked
Dec 22 17:36:24 hostname com.apple.launchd.peruser.1340[6375] ([0x0-0xa42a42].com.filemaker.filemakerpro[43304]): Exited with exit code: 255
Dec 22 17:36:24 hostname parentalcontrolsd[43221]: -[ActivityTracker(Private) _removeAppFromWhiteList:] [1362:user] -- * Couldn't find local user record
So, even though the apps are listed in Workgroup Manager and are unsigned, and also appear in '/Library/Managed Preferences/user/com.apple.applicationaccess.new.plist', it appears that the client somehow thinks they don't match what's in the whitelist even thought WE DON'T SIGN THEM WHEN WE ADD THEM!
What might be causing this? Any further troubleshooting tips would be GREATLY appreciated!

According to the [Code Signing Guide|http://developer.apple.com/library/mac/#documentation/Security/Conceptual /CodeSigningGuide/Procedures/Procedures.html#//apple_ref/doc/uid/TP40005929-CH4- SW2], it appears that there is no way to remove signing (emphasis mine):
"You can take a partial-update approach to revising your code on the user’s system. To do so, sign the new version as usual, then calculate the differences between the new and the old signed versions, and transmit the differences. Because the differences include the new signature data, the result of installing the changes on the end-user's system will be the newly signed version. You cannot patch a signed application in the field. If you do so, the system will notice that the application has changed and will invalidate the signature, +and there is no way to re-validate or resign the application in the field.+"
Upon further investigation, the version of FileMaker 5.5 in question appears to be signed even after a fresh install from original install media. I wouldn't have thought Code Signing was around back then (2001). And the code signing appears to match between the fresh install (to a new location) and the original install. I'll attempt to sign it in WGM and install the same, signed copy everywhere.
Also, I looked at one of our other working primary applications (4D.app) and it is unsigned, but appears in the Firewall as "Allow incoming connections", so I don't believe that the Application Firewall is necessarily signing apps automatically (but I certainly won't be ruling it out).
I haven't checked yet, but the other application that's failing is "Parallels Desktop 6", which I'd bet is signed. I wonder if the "Automatically allow signed software to receive incoming connections", which is checked, would come into play at all?
Thanks for pointing out how to use `codesign` to check whether an application is signed or not, this seems to be the first real break on this case.

What are the general errors will come in data uploading

Hi Friends,
What are the general errors will come in data uploading
Thanks in Advance

Paul
It all depends on how we configure the system. Errors may be different for different scenerios like
User ALEROMOTE Loacked for master data's
Data Sourcs has to be replicated
Activation Failures
Error occures in data Selection Etc.
Do you have any specific error so that we can work on that.
Thanks

An answer to the "General Error"

I'm in the process of importing old VHS tape through a Canopus ADVC-300 into FCE and prepping the video for DVD via iDVD.
In the process of exporting one of the tapes, FCE generated the "General Error". My queries on this forum found many posts from folks looking for an answer to the same error, albeit not always from the same set of circumstances.
For me, it turned out to be a specific frame of imported video. I located it by selecting half the video for export via In and Out points and exporting only that half. During export, if the error would occur I would further divide that half of video in half again and export. I did this 7 times (you don't need to subdivide any more than this) and relatively quickly located the specific frame of video that was causing the problem.
I cut out that single frame and then exported the entire sequence without generating the "General Error" problem.
It is helpful to note that the export processes the video linerally from left to right. Noting where in the export process the error occurs helps narrow down the general area to look in and which half of video to export to find the problem frame.
Hope this helps others figure this one out.

"In the process of exporting one of the tapes"
From this I understand the General Error was caused during capturing (exporting) the tape.
That sounds like it may have been a timecode break on the tape.

Intermittent "Cannnot send message using the server" error

I've been getting an intermittent "Cannnot send message using the server" error for a couple of months now. It happens every 3 or 4 e-mails I try to send or reply to. I select "Try Again Later" and then open the message from the Outbox and resend with no problem.
My setup is;
Mail 2.1.1
OSX 10.4.9
MacBookPro
CableVision is my provider
It's a POP account
My incoming server is pop.secureserver.net
My outgoing server is smtpout.secureserver.net
Server port 3535
Authentication - Password
SSL is off
Any help would be appreciated

Hi Dave, and a warm welcome to the forums!
No expert on this, but I wonder since your using the secureserver, if SSL might not work better.
Or maybe try...
Incoming Mail Server Name (POP3): pop3.optonline.net
Outgoing Mail server Name (SMTP): smtp.optonline.net
or mail.optonline.com for both!?
Nearly impossible to find any help on Cablevision's site.
Also, I wonder if this might have something to do with Tiger's Mail also...

Simulation Interface Toolbox: Problems using sbRIO with Tutorial: "Using the Example Sinewave Model with a VxWorks CompactRIO Target"

Hello
I faced a problem when I tried to do the Tutorial "Using the Example Sinewave Model with a VxWorks CompactRIO Target".
My specifications are:
Software:
Win7 64-bit
Matlab 2010b with RTW (to compile the *.dll) (32-bit)
GNU-Toolchain 6.3 running in Virtual PC-XP-Mode (to generate the *.out)
Labview 2011 with Simulation Interface Toolbox 2011 (32-bit)
Hardware:
sbRIO-9631 (from Labview Embedded Platform Evaluation Kit)
I was able to compile a dll and an out file.
I created a custom fpga-Bitfile with the Tutorial "Creating a Custom FPGA Bitfile".
In a blank VI I made the Host-VI and with the SIT Connection Manager I created the Driver VIs.
Until here everything worked fine.
Now my problem appeared. As long as I don't create Hardware I/O Mappings my model runs fine on the sbRIO:
But when I try to map the in and out port of the model to a HW I/O I get this error:
What causes this error?
On my sbRIO following software is installed (followed this instruction: Configuring a Real-Time Target to Run the LabVIEW SIT Server)
Best regards
Patrick

I have exctly the same issue. here is my error
my fpga for the bitfile
my driverVI
and my installed software

Cloning use the different gcc version between source system and target sys

Hi All,
Our system is: Application tier and Database tier is split to two servers.
We should run a cloning, but I found the different gcc version on application tier on source system and target system.
The source application tier server is RedHat Linux ES3, gcc version is 3.2.3
The target application tier server is RedHat Linux ES3, gcc version is 2.9.6
There is the same gcc version on database tier on source system and target system, they are gcc 2.9.6.
My question: Can I use the different gcc version between source system and target system when I run an erp cloning?
Thanks & Regards
Owen

Not necessarily, you might get some errors if the version is higher and it is not supported by the OS. An example is Note: 392311.1 - usr/lib/gcc/i386-redhat-linux/3.4.5/libgcc_s.so: undefined reference to 'dl_iterate_phdr@GLIBC_2.2.4'
To be on the safe side, make sure you have the same version (unless you want to give it a try).

General Error Handling - use of FEH (PPO/ECH)

We are investigating the usage of Forward Error Handling, known with SAP as PPO (Post Processing) and ECH (Error Capture Handler) to be able to re-process errors (automatically or manually) from incoming messages.
I am interested in talking with anyone who has implemented this. General questions are:
- how have you found it to work in real life?
- configuration/set-up straight-forward?
- what scenarios have used it in?
- incorporated into your custom services?
But am interested in any comments.
I am posting this within the PI forum as it ties into the fact we async scenarios inbound to SAP, typically from our PI system, and when those scenarios encounter an error we are looking for a way to have a business/end user - friendly interface for reprocessing the error. Implementing a proxy scenario, and thus having the errors show within sxmb_moni/sxi_monitor, is probably not going to work for us - too technical. I am also aware of an add-on, AIF I believe, but our company is not interested in installing that.
There are 4 blogs out there that I am aware of - 2 from Tobias and 2 from Michal. Very informative. I am finding some config not as ours though. Am really interested in anyone has really implemented and used this in a prod environment.
Regards,
Keith

I think I am exactly at the same position as you in figuring out the usage of FEH in an environment. I just completed a small document (for internal purpose) that I prepared gathering all the information from those blogs, SCN and TechEd. Here are my 2 cents:
>>- how have you found it to work in real life?
We haven't implemented it yet. But we believe it will be quite useful in handling business specific errors. We are trying to find out if it can be merged with the existing BPEM infrastructure to generate BPEM cases.
>>- configuration/set-up straight-forward?
Yes, the blogs should be quite useful to provide this information.
>>- what scenarios have used it in?
Most importantly it will be used for standard service implementation where we consume enterprise services from ES workplace. These services have FEH capability built in (they have FEH method implemented within). The scenarios are of course inbound abap proxy.
>>- incorporated into your custom services?
We are still in design phase. But if you ask me about it, i would say yes you can and I think you should use it for custom ones as well.
Kind regards,

How to use Request header in the OSB error handler

Hi
I have a scenario where OSB proxy service accptes the payload and routes to the target service
and before routing, I'm generating UUId and inserting in to the request header and publishing the request payload along with UUID to another service.
when the target service is thrown some business fault,i need to publish the fault along with the header(which has UUID).since my target service sends only fault body,header is getting emptied in the error hanlder section.
How can I use the requestheader in the error handler section. Any help is highly appreciated.
Thanks,
N

Just assign your request header ($header) to your variable (e.g. $myRequestHeader) and than use this variable in your error handler. Fault response will override your $header but can't override $myRequestHeader.

General error handling operation

Hi,
I did not find a comprehensive explanation how error handling works in TestStand, only bits and pieces about the callbacks (perhaps I looked at the wrong places).
Anyway, I made some experiments with SequenceFilePostStepRuntimeError and StationPostStepRuntimeError - intentionally leaving out ProcessModelPostStepRuntimeError to reduce complexity - and came up with the attached flow chart. I would like to know:
if that shows the correct operation of TestStand error handling (we are currently using 4.1, about to switch to 2010 or 2012, so it would also be interesting to know if anything changes with the new versions)
if it is always the case that the combination of ErrorReported=True und Error.Occurred=True after the error handler leads to termination of the execution? I could not find any setting governing that (the "goto cleanup immediately" setting of the sequence was off;
Best regards
Peter

Hi Peter,
1) Every step has :
error.code - to set the error code
error.occured - boolen if set true displays a popup error message to the user
error.message - the popup contains this message
when you set error.occured=true it will bring up a popup message with the error.message and error.code.
Please note that this may not be acceptable in the manufacturing environment where operators may not be trained to check for errors.
The general practice in manufacturing is to fail all important steps that errors out so that the final result is failed.Then do a offline analysis.This is done by step.results.status = "Failed".You can also populate step.results.ReportText with proper values so that your test report reflects the type of error/failure.
2) Regarding the SequenceFilePostStepRuntimeError and StationPostStepRuntimeError - they are optional error handling methods if you want to act on errors.
3)Every step has an option ( look for properties-->post actions).On Pass or On fail destinations can be set for each step.Cleanup is always executed except in cases of abort.
4) In the menu configure-->Station options-->execution there is an option for runtime errors ( one of them is run cleanup).
Hope the above information helps.
