Parallel model using different testsequece.

Hi
How can i use the parallel or batch model to call two different test sequences?
The idea is two run the one test then imediately the test one.

How to Use Same Models in Different DC's.

Hi Experts,
I want to use same Models in Different DC's. How I achieve it by adding Model to Public parts.
With Regards,
Roop Kumar.

Hi Roop,
It's enough to reimport Only Parent DC. No need to change in Child DC
This depends on scenario according to my experience.
Changes to the model definition can be three ways
1)Addition: Adding new fields or structures to your model.
In this case "It's enough to reimport Only Parent DC. No need to change in Child DC", if you are not using the new fields or structures in child DC.
2)Modification: Modifying existing fields or structures (e.g. data types) in your model.
In this case "It's enough to reimport Only Parent DC. No need to change in Child DC", because fields or structures in child DC are reference to the Parent DC.
3)Deletion:Deleting fields or structures in your model.
In this case, "It's enough to reimport Only Parent DC. No need to change in Child DC", if you are not using the deleted fields or structures in child DC.
But this holds if you make your DC as a public part but not the model and the parent DC's Interface Controller must have the context that you are going to use in child DC. You will find more help [here |/docs/DOC-8661#section5]

When to use parallel models?

I am using TestStand to control test execution in a thermal chamber. I am unsure which process model best suits my needs (sequential, parallel, or batch). My requirements are as follows:
Up to 4 UUTs will be tested using a single test system. Each UUT shares assets in the test system. An entire sequence of tests will be run repetitively on each unit for a period of 24 hours. Within the 24 hour period, a single control signal is received from the thermal chamber indicating when tests should be run. (run for two hrs, soak for two hrs; run for two hrs, soak for two hrs �). Typically (prior to using TestStand) the test controller would run all tests on UUT#1, then all tests on UUT#2, then all tests on UUT#3, and so on. At the completion o
f this cycle, testing for UUT#1 would occur again. Each UUT has its own data report generated.
I know the parallel process model allows for the removal and/or addition of UUTs at any time during the test sequnce. Although that is a nice feature, it is not a necessity.
I would appreciate some advice on how to handle this situation. How can I affect the �infinite looping� of an entire test sequence for this multi-UUT environment?

Maz,
in the TestStandI course they stated that the serial model is for serial testing of one UUT after the other. The parallel model could somehow be assumed as multiple serial models running in parallel. The batch model is somehow inbetween or extra. It handles the test of a whole batch of UUTs in parallel, where there are some things to be tested in common.
Of course everything can be coded in every process model, but this would give up a lot of the built-in comfort.
In your case I would choose the parallel model, except there are some steps that need to be done on the whole batch at the same time. Consider some UUTs that must all pass a voltage test where you have just one DMM, and must be cooled down when all are done. This would be a batch model.

Using different jacob.dll verions parallel on the same PC-Client ?

I need to work with Windows7 Client and IE-Browser with SunJava-Plugin 6_u29
against
a WLS 10.3.5 / Forms 11.1.1.4 application
alternately with
the 'old' AS10g / Forms 10.2 - version
that works ok except using client_OLE2
I found, the reason is the different jacob.dll
in forms 10g and forms 11g
for using 10g the jacob.dll is in JRE6/bin-folder
for work with WLS the jacob.dll is in the folder c:\webutil
defined from install.syslib.location.client in webutil.cfg
is there a way to work on client different with both jacob.dll ?
a) can I define & using different search-Pathes ?
b) is there a Jacob.dll -Version for running on both AS 10g and WLS 10.3.5 ?

That's true... you can use whatever combinations you like, but the Oracle certification represents what they have tested and will guarantee to work. If a certified configuration does not work correctly, a bug can be filed against the issue and usually be corrected. Uncertified configurations are technically not entitled to support or bug filing. In some cases, Oracle may support it, but they are not required to.
As for what I mentioned regarding Jacob, I do know that technically, unless you are using the versions I mentioned (of Forms) you will not be able to accomplish what you want... at least not in a supported manner. By using the Forms patches I mentioned, you will be able to custom set the client destination directory of the libraries, which I believe is what you wanted in the first place. However, the result of installing those patches requires that you upgrade to Jacob 1.10.1 in order to be compatible with the Forms upgrade, which is the same version used by Forms 11.1.1.x. So, in this case, even though patching will let you customize the target directory, you won't need to do that because both versions will be using the same Jacob version. That said, if you have Win7 client machines, those patches and new jacob version will be needed to overcome some Win7 security restrictions.

Help with the Parallel Model configuration

This is my first time posting, but I am a long time reader....
First off, I would consider my Teststand knowledge level as high novice to low intermidiate. I created a test sequence using in Teststand which calls labview vi's. My test sequence tests 5 units at a time in a parallel model (parallel model sequence). Functionally, everything runs great in single pass and looping. However, here is my issue:
When selecting "Test UUT's", it brings up a window that asks for the serial number for each of the five stations. The operator then needs to enter a serial number for each and press okay to proceed. This setup is not valid for what I am doing. My test fixture has a button at each of the 5 stations. The user is to push the button to start the test (connects to a DAQ). Then, the serial number is read from the UUT and populated in the report.
How would I go about reconfiguring this? I am not looking for someone to solve my problems for me, I just need a little direction. I looked at the parallel model sequence and I can't figure out where to go with it.
Please help,

No problem Ryan,
When you are done here you will be a pro.
Here is a link that talks about callbacks and how overriding them works: http://zone.ni.com/devzone/cda/tut/p/id/6605
The PreUUT will be a Model Callback.
One thing I should point out- There is a huge difference between the Batch Model and the Parallel Model. People tend to get them confused and sometimes use the wrong when the other one is a better fit for their architecture. They way I think about it is like a race track. Each car on the track represents a different test socket. One time around the track represents a full test. Pretend the race is completed by teams of cars. Each team can only race one car for one lap (sorta like a relay). The team would represent the available test fixture for the next UUT and the car would be the UUT. Here's how the race would work with each model:
Batch Model- Let's say there are 2 available spots in the race so we have 2 teams of 5 cars each. Both of the teams 1st cars would line up at the starting line. The gun would go off and each car would take off. Let's say team 1's car gets around the lap first. Before they can start their 2nd car they have to wait for team 2's 1st car to get around the track as well. Then both team's 2nd cars would line up and continue the same as the first go around and so on until all 5 cars had raced.
Parallel Model- In the same car scenario as the Batch Model both of the team's 1st cars would line up and the gun would go off and they would go. However, this time if team 1's car gets around the track they can immediately send their second car without waiting for Team 2's 1st car. In fact all 5 of team 1's cars could be finished before team 2's 1st car even finishes it's lap.
Not sure if you are a fan of analogies but they work for me. In short-
Batch Model- Everything in that set of test sockets must start and stop at the same time.
Parallel Model- Each test socket is independant of any other test sockets.
I'm picturing your scenario where you have 5 different stations that will be running independantly of each other and trying to figure out if you would want the Batch behavior or the Parallel behavior. Or..... Why wouldn't you just use the sequential model on each station and deploy your sequence to each station? Maybe you can describe your setup in a little more detail and we could come up with a better solution.
How does the one station know that the others have the Go button pushed?

Parallel model questions

I have a few questions about how to implement a parallel model multi-socket test.
So, we have a test board which is controlled by USB (1 per board).
I have developed a VI based test sequence, that runs fine in a single mode.
Now i need to rconfigure this to use 2 sockets to run 2 iidentical test simultaniously (asynchronous)
A few things are unclear to me in the implementation:
1. Are the variables common to the 2 instances, or separate? For instance i use a local which is the handle to the comms for that board, but do i now need a different local variable for each socket? If yes, i dont see how that would be implemented, because the variable is specified in the sequence.
2. How to define constants that will apply only to one or other of the sockets (i.e. the board usb port)
3. Is it really multi-threaded? i.e can i call the same VI in 2 instances?
Labview 2010, TestStand 2010

Hi,
1. Do you have one resource or you multiple comm ports?
2. You can use the Socket index to get the correct data, off course you would have to use an array to hold this data. If handles are not from a shared resourse then there is no need for any special consideration. Each Socket will be totally independant of each other. Its only when resourses are shared that you need to make sure each socket is not trying to use it at the same time.
3. Providing VI are re-entrant then you can multiple instances of a VI in memory. Otherwise you would have to use synchronization so that you can share resourses.

Loop counter reset in parallel model ?

Hello,
i am using TestStand 3.1 with parallel model. There is a loop counter for each UUT in RunState.Root.Parameters.TestSocket.UUT.UUTLoopIndex. This increases with every loop that is done.
Now my problem is: If i start the NextUUT, this counter is not set to 0. It just increases.
Is there a different counter that i can use ? Or where can i get the information that the NextUUT button is pressed so that i can reset the counter manually ? Or is there another solution.
Thanks for Help.

Hi,
I don't completely understand, why you want to reset the UUTLoopIndex, because it shows the number of iterations per test socket to check how many uut's have been tested on each. However, you could reset the value with a simple statement before you start the tests. You could do this in the setup step group, e.g. with RunState.Root.Parameters.TestSocket.UUT.UUTLoopIndex = 0. You could add a message popup or evaluate an extra condition or so.
Kind regards,

Creating a custom UUT dialog for the parallel model

Hello,
I am attempting to customize the parallel process model in order to (amongst other things) present a different UUT info dialog. (The default one defined in modelsupport2.dll only presents a single "Serial number" field where I need numerous other ones.) Because I am not familiar with CVI (and don't have the development tools for it), I was hoping to create an ActiveX DLL in Visual Basic, or a .NET assembly to manage a slightly more complex version of the UUT info dialog... While I am sure it would be great fun to fumble with all the complexities of this until it shows some semblance of proper functionality I am hoping there may be some resources available online that would demonstrate how one would go about doing this kind of thing. I've seen LabVIEW code that provides a different UUT dialog, but it was based on the sequential model which circumvents the most complex issues such as synchronizing the dialog with the TestStand threads, etc. Any pointers would be greatly appreciated.
Thanks!

I am just posting this in case anyone else runs into the same sort of requirement. The attached zip file contains the source for a .NET assembly that is the beginnings of a VB .NET replacement for the parallel UUT dialog of the modelsupport2 DLL. I don't want to write an epic here, so the general idea is that the parallel model sequence is modified to make calls into this assembly instead of the modelsupport2.dll component. But you can't just disable the dialog by setting the ShowUUTDlg boolean to false - that will completely remove the consumer loop in the ProcessDialogRequests sequence which the .NET assembly is trying to send requests to. I've attached the modified ParallelModel.seq in case anyone's interested.
Note that there are still significant problems with this and it is provided as-is. In particular, if you attempt to break and step through the parallel model sequence after the dialog has been initialized, you will not be able to continue - the main thread will hang until you restart TestStand. With a little more thread mgmt, that could be fixed. If nothing else, it is useful code to look at if you need to enqueue items from a .NET assembly into a queue defined in a TestStand sequence.
If you can afford to use the existing dialog as-is, and then add additional info gathering to the main sequence, that is clearly easier. (That will be OK for my purposes so that is what I'll do.) However, if you need to have one custom dialog that manages everything in the parallel model, this is the kind of code you should expect to need.
Hopefully that helps somebody. There is not much info out there about integrating .NET at this level.

Replacing the default Parallel model UUT Dialog

What is the best way to replace the default UUT Dialog for the parallel model? I don't want to modify the default parallel model, but use the callback options in my sequence to replace the default UUT dialog.
Things already tried:
1) Generated a UIR to replace the default UUT dialog.
2) Placed an action to call the new dialog into the PreUUT callback.
3) Created a statement function that change the status to display the default UUT Dialog and place into the ModelOption callback.
This replaced Default UUT Dialog with the new UUT dialog. But the new UUT Dialog panel shows up in four different panel, one for each of the four socket being executed.
The goal is to have the new UUT Dialog appear only once to handle all 4 sockets. The default parallel model initialize the default UUT dialog panel then uses display panel to view UUT dialog. Is there a different method to have the new UUT Dialog panel appear only once for all four socket inputs and not multiple times?

There is an example for this under the directory:
<TestStand>\Examples\ProcessModels\ParallelModel
Edited: Just realized that what you asked is a bit different than the example.
I recommend you try one of 2 possibilities:
1) In addition to disabling the old dialog as shown in the example,
override the ProcessSetup and ProcessCleanup model callbacks and add
your code to display and remove your dialog there (you should probably use a "new thread" sequence call when displaying the dialog so that it has its own thread for message processing). Then also override
the preuut callback and add code to communicate with your dialog in
some way to pass and return the necessary information for each
testsocket. This could be a dll call or some other way of doing this communication.
2) Modify the existing code for the current dialog or implement something similar. The code for the dialog is in the cvi project for modelsupport in the same directory as the process models. If you are going to modify this dll you should copy the Models directory from Components\NI to Components\User and modify the version of it there. The Components\User version will override the version under Components\NI.

What is the best way to open close and pass instrument handles from labview in teststand parallel model?

I have a number of test systems that use a parallel model with labview. We have a good number of instruments(PXI).
What is the prefered method for open,closing and passing instrument handles in teststand using labview?
Solved!
Go to Solution.

Hi,
No, Below is a bit from the Session Manager Help
Currently, Session Manager supports the following instrument session types:
IVI Sessions—Use an IVI session to obtain the C-based instance handle for an IVI logical or virtual instrument name. NI Session Manager does not support IVI-COM drivers at this time. When IVI-COM drivers are available, you can use an IVI session to obtain an ActiveX interface reference to an IVI-COM driver.
VXIplug&play Sessions—Use a VXIplug&play session to obtain a C-based instance handle for a VXIplug&play logical or virtual instrument name. Configure VXIplug&play names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
VISA Sessions—Use a VISA instrument session to obtain a C-based viSession handle to a VISA resource or logical name. Configure VISA logical names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
Custom Sessions—Use a custom session to create a data container object that shares ActiveX objects you create or other data between software components you write. Use the Attach and Get methods to attach data to and retrieve data from a session. A custom session does not initialize, close, or own an instrument handle. The data you share with a custom session does not have to be instrumentation related. You can create a custom session with any name you request.

How to host one application using different database connection on OAS?

Hi,
Jdeveloper - 10.1.3.4
Application - ADF/BC
Oracle Application Server - 10.1.3
Above our the specifications for our application,
We have two database schemas different for development and production therfore we have different databse connections for the two,
we have one application which is in production and enhacements on the same application are done by the development team.
Since we have two different schemas for developement and prduction we use different database connections for the application on development and production.
The problem is our Model and View Controller project are same, only the database connection file changes that's why we are able to host only on application at a time on our OAS. This is probably because the URL generated by OAS for developemnt and prodyction application is same.
Is there a way we can host two instances of the same application with two different database connections on the a single OAS.

How to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller

we are using VS 2013, I need to run multiple Coded UI Ordered Tests in parallel on different agents.
My requirement :
Example: I have 40 Coded UI Test scripts in single solution/project. i want to run in different OS environments(example 5 OS ). I have created 5 Ordered tests with the same 40 test cases.
I have one Controller machine and 5 test agent machines. Now I want my tests to be distributed in a way that every agent gets 1 Ordered test to execute.
Machine_C = Controller (Controls Machine_1,2,3,4,5)
Machine_1 = Test Agent 1 (Should execute Ordered Test 1 (ex: OS - WIN 7) )
Machine_2 = Test Agent 2 (Should execute Ordered Test 2 (ex:
OS - WIN 8) )
Machine_3 = Test Agent 3 (Should execute Ordered Test 3
(ex: OS - WIN 2008 server) )
Machine_4 = Test Agent 4 (Should execute Ordered Test 4 (ex:
OS - WIN 2012 server) )
Machine_5 = Test Agent 5 (Should execute Ordered Test 5 (ex:
OS - WIN 2003 server) )
I have changed the “MinimumTestsPerAgent” app setting value
as '1' in controller’s configuration file (QTController.exe.config).
When I run the Ordered tests from the test explorer all Test agent running with each Ordered test and showing the status as running. but with in the 5 Test Agents only 2 Agents executing the test cases remaining all 3 agents not executing the test cases but
status showing as 'running' still for long time (exp: More then 3 hr) after that all so its not responding.
I need to know how I can configure my controller or how I can tell it to execute these tests in parallel on different test agents. This will help me reducing the script execution time.
I am not sure what steps I am missing.
It will be of great help if someone can guide me how this can be achieved.
-- > One more thing Can I Run one Coded UI Ordered Test on One Specific Test Agent?
ex: Need to run ordered Test 1 in Win 7 OS (Test Agent 1) only.
Thanks in Advance.

Hi Divakar,
Thank you for posting in MSDN forum.
As far as I know, we cannot specify coded UI ordered test run on specific test agent. And it is mainly that test controller determine which coded UI ordered test assign to which test agent.
Generally, I know that if we want to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller.
We will need to change the MinimumTestsPerAgent property to 1 in the test controller configuration file (QTControllerConfig.exe.config) as you said.
And then we will need to change the bucketSize number of tests/number of machines in the test settings.
For more information about how to set this bucketSize value, please refer the following blog.

A special Rendezvous that works on subsets of processes in the parallel model

I have a parallel model test that works great on 14 UUTs so far, but now I must write some sequences where the processes have to share hardware two at a time. I need to pair up the processes like (0,1), (2,3), (4,5), etc. and have a Rendezvous operate on them two at a time like this:
Processes (0,1) operate in parallel.
Processes (2,3) operate in parallel.
Processes (4,5) operate in parallel.
And so on....
Given enough time, maybe I could write that programmatically in TestStand; but I hope TestStand has a built-in Rendezvous for subsets of processes, or something else to do that. Does such a thing exist?

bmihura wrote:
OK I tried your pairing up idea with six processes (three seperate Rendezvous, one for each pair), but they all still ran in parallel. I'd like for one pair to execute at a time while locking out the others. This is because my system has two electronic loads (and two of many other things) that the six UUTs must share.
Ok, then what you proposed before (a separate rendezvous for each pair of threads) is not the correct way to synchronize things. A rendezvous just causes threads to block until the specified number of threads reaches the rendezvous point. You have three independent pairs of threads running in parallel. If that is not what you want, then using rendezvous like this isn't the right approach.
Please describe in more detail the entire flow of execution you are looking for. At what scope do you want the other threads to be blocked? Do you want each pair of threads to run all tests before any other threads can run? Do you want this only around certain steps? or Group of steps? Also, why do you want the threads to be paired? The most straightforward way I can think of to allocate two of a resource is to not care about which thread is using it, but to only allow two threads at a time, they don't necessarily have to be in pairs or even the same two threads every time. Do you really need the threads to be paired?
One of the simplest TestStand specific ways to allocate resources is to use the auto-schedule step types. They allow you to define blocks of code which require specific resources and then automatically run those blocks of code when those resources are available. I recommend you read the documentation for these step types and see if that sounds like it will work for you.
Another relatively simply way to synchronize access to a fixed number of resources among many threads is with a semaphore. A semaphore allows a certain number of threads through at a time, and blocks other threads until one of the ones using the resource release their acquisition of the semaphore. If the resources involved are more complicated though, I think you are better off using the auto-scheduler step types.
Hope this helps,

Schedule parallel activities on different resources for the same period

Hi,
I am trying to create a PPM where I need to define parallel activities on different resources for the same time period.
For example:
Input prod: P1
Output prod: O1
Now I define a dummy activity A1 to define this consumption i.e. 1 PC of P1 gives 1 PC of O1.
Now I have got 3 resources R1, R2, R3.
I define 3 activities A2, A3, A4 for these resources.
Now I have to arrange activities A2, A3, A4 such that they start simultaneouly after activity A1 and also end simultaneouly.
The Fixed duration for all the resources is 1 week.
My requirement is that out of these resources system should plan for demand considering the resource with minimum capacity
i.e. kind of bottleneck resource.
I am using CTM engine for planning.
I have defined A1 as predecessor for all the 3 activities A2, A3, A4 and after completion all the activities have a dummy successor activity S.
But this setting is not working and PPM is not getting exploded, If I use a normal linear relationship between activities it works fine but my requirement is not getting satisfied.
Can anyone please help me in this case or suggest some alternate method.
Thanks & Regards,
Sanjog Mishrikotkar

SequenceFileUnload in TestStand 4.0 Parallel Model

Has anyone experienced a problem when updating to TestStand 4.0 with the SequenceFileLoad and SequenceFileUnload callbacks? I’m using the parallel process model configured for 8 threads and in earlier versions of TestStand have had no problems placing my hardware initialization steps in the SequenceFileLoad callback and the cleanup steps that release hardware references, in the SequenceFileUnload. It seems very random that sometimes when I close my sequence, the Unload steps are executed. Sometimes they only run if I select File->Unload All Modules or close TestStand.
Is there a flag in TestStand that I can use to trigger the Unload steps or possibly a better place in the parallel model to place my hardware cleanup? I don’t want to release and have to reinitialize hardware references with each loop so any cleanup steps will need to be done once after all parallel threads are finished.

Most of the time people do this in the Process Setup Callback and Process Cleanup Callback. Those are process model callbacks that you can override from your client sequence. They are probably better to use than the engine callbacks (SequenceFileUnload and SequenceFileLoad). They get executed before and after the looping respectively.
If you open the process model you'll see where they get called. Process Setup Callback is in the Setup step group and Process Cleanup Callback is in the Cleanup step group.
