How to protect process model being modified (using Teststand3​.1)?

I'm developing a custom Process model, and don't want to be modified by others. I know there's a password protection function in Teststand3.5 but not available in Teststand3.1. Is there any other methods to prevent my process model  being modified by others in Teststand3.1??
Thanks!
Jacky

Protect from whom? Are you using the user manager and are you checking privileges? If you want to protect the process model fro other TestStand administrators, I'm not sure what you can do but the default privileges prevent operator and technicians from editing a sequence file or process model and if you can use the user manager to change the Developer profile Privileges>Configure>Edit Process Model to false.

  • How to push Process model to design model?

    I just learned how to capture business requirements and a logical design using the logical data modeler and process molder to create data flow diagrams, with composite, primitive and transformative processes in SQL Developer 3.0
    I know in Oracle Designer we were able to associate entities to business functions and transform the business functions into modules of type PL SQL or screen, etc.... We could create detail design documents from this information in Oracle Designer. In Oracle Designer the modules would be associated to the physical table definitions. However, the data flows in SQL developer are associated to logical entities.
    My question is can these objects/items (processes primitive, composite, transformative) be transformed into design items similar to how we transform a business function in Oracle Designer into a modulel?
    Thanks

    Hi Mark,
    there is no support for applications and modules in Data Modeler.
    Design can be exported to reporting repository and there is no limit in how you can utilize these meta data. Column groups and UI defaults can be defined at table and column level - I know some people are generating APEX applications and process model can be very helpful for that.
    In Oracle Designer the modules would be associated to the physical table definitions. However, the data flows in SQL developer are associated to logical entities.Each entity can be mapped to unlimited number of implementations in form of tables in relational and physical models. You need to engineer logical model to one or more relational models. There is small wizard appearing in context menu of data flow diagram node in browser - "Transform Process model roles to Physical role". You can create roles in process model and assign them to processes connected to data stores. Then this wizard will create these roles in selected physical model and CRUD settings will be transferred to permissions to select, insert, update and delete for related tables. This is just example that physical model can be reachable from process model.
    We'll add more utilization of definitions in process model in future releases.

  • How to release process model sequence file object?

    Calling engine's method GetStationModelSequenceFile we get the reference to the process model sequence file object. According to TestStand Help, you should "Release this reference when you are done using it." The question is: how do you release it? Call engine's method ReleaseSequenceFileEx passing the reference to the model sequence file gotten from GetStationModelSequenceFile won't work, it returns FALSE which means the sequence file can't be released. Similar problems exist with methods SequenceFile.GetModelSequenceFile, Execution.GetModelSequenceFile. My aplication is written in VB. Using the statement like
    Set modelSequenceFile = Nothing also does not solve the problem.  I want to get some information of process model, such as version number, so I call those API functions in my code, which was developed under TestStand 3.1. I post this question because when I ran my application with TestStand 3.5 or 4.0 beta, I got the warning dialog when loading a sequence file and then closing the application. The dialog listed all the unreleased objects which I figured out is due to that the process model file was not released. Because message in the dialog is as following:
    The following top-level objects were not released:
            Sequences [1 object(s) not released]
                Sequence #1:
                    Name: Test UUTs
            Type Definitions [43 object(s) not released]
                Type Definition #1:
                    Name: TimeDetails
                Type Definition #2:
                    Name: ReportOptions
    Of course there are more in the list, but the sequence file loaded into the application is released correctly by calling engine's method ReleaseSequenceFileEx, so it does not appear in the list.
    Any help will be greatly appreciated.

    Here are what I did after launch the operator interface:
    1) Call Engine.GetSequenceFileEx to get a reference to a sequence file.
    2) Display steps of MainSequence of the sequence file in GUI.
    3) Call Engine.GetStationModelSequenceFile to get a reference to the station process model sequence file. The variable used to save the reference of process model sequence file is modelSequenceFile.
    4) Loop through all the sequences in process model sequence file, get the references of entrypoint sequences in the process model and put them in a container (VB Collection).
    At this point,
    Calling modelSequenceFile.CanUnload returns TRUE
    Calling modelSequenceFile.IsExecuting returns FALSE
    Calling Engine.ReleaseSequenceFileEx(modelSequenceFile, ReleaseSeqFile_UnloadFile) returns FALSE
    There is no other loaded process model sequence file reference at this point.

  • How to add process model results to the sequence file results?

    After my sequence file runs, I would like to add some additional results using the process model. I need to log my equipment list which is obtained by the process model. Alternatively, I could add a sub-sequence to the end of each of my sequence files for doing this, but that would create maintenance problems if I ever needed to change the way equipment is logged. Does anyone know a way to (1) append process model results to the sequence file results or (2) force each client sequence file to call a sub-sequence before returning to the process model.

    Mark -
    The report and database process model routines expect a single subsequence step result that invoked MainSequence. This result contains the results from the sequence call.
    In TestStand after the process model root sequence call to MainSequence is performed, the property Locals.ResultList[0] is the MainSequence result. The subproperty Locals.ResultList[0].TS.SequenceCall.ResultList contains the results from the steps in MainSequence.
    One option is to create a subsequence call in the process model that logs the equipment info in the results for its steps. The call to the subsequence should not be checked to record results.
    This subsequence would have a parameter called ResultList. The Result type does not exist in the Insert menu, so you can only create the parameter by copying the empty Locals.ResultList and pasting it in the parameters. Then change its type from By Value to By Reference.
    In the setup of the subsequence, add the following steps which do not record results. These steps rename the Locals.ResultList parameter to ResultListOrig, and then create a new Locals.ResultList alias property that really references Parameters.ResultList. This way any additions to the Locals.ResultList really append to the Parameter.ResultList.
    Setup
    Step: "Rename Locals.ResultList"
    StepType, Adapter: Action, Active-X
    Description:
    Action, Set PropertyObject.Name = "ResultListORIG"
    Record Results: False
    Step: "Create Alias in Locals"
    StepType, Adapter: Actioin, Active-X
    Description:
    Action, Call PropertyObject.SetPropertyObject ("ResultList",
    0x201 ' Not Owning and Create, Parameters.ResultList)
    Record Results: False
    In the Main steps, you add your equipment info steps which record results.
    In the Cleanup steps you undo the steps performed in Setup.
    Cleanup
    Step: "Delete Alias in Locals"
    StepType, Adapter: Action, Active-X
    Description:
    Action, Call PropertyObject.DeleteSubProperty ("ResultList",
    0x400 ' Refer to Alias)
    Record Results: False
    Step: "Rename Locals.ResultListORIG"
    StepType, Adapter: Action, Active-X
    Description:
    Action, Set PropertyObject.Name = "ResultList"
    Record Results: False
    I have attached a TS 2.0 version of SequentialModel.Seq that has a AppendResults subsequence in it and this is invoked after MainSequence in Single Pass entry point.
    Hope this helps...

  • How to protect applications running in Weblogic using OAM

    Hi all,
    I have a doubt,
    I have 2 application running in weblogic.
    I need to protect those application using OAM and provide single sign on.
    How this can be done?
    In the OAM integration guide i saw OAM with BEA Weblogic SSPI
    Is SSPI like a connector r what is the use of this?
    Is there any other way to protect a application running in weblogic using OAM and provide SSO for those applications
    thanks in advance.

    You will need to also add the OAMIdentityAsserter and possibly an Authenticator to get group/role information in the weblogic instances (assuming it's not the same one where OAM is installed).

  • How to protect application from being run by 2 browser with same session ?

    Hi all,
    As we know, in Firefox, if we open two browser windows or tabs it will share same session. In IE, it does the same thing if we open two tabs in same window.
    The impact is user can open the application twice (or more) yet share the same session. This will result in unwanted behaviour in our application.
    (ADF Faces 10.1.3.3 + BC)
    Is there aniway for us to disable user from opening the same application in the second Tab (IE) or second Browser window (Firefox),
    eg :
    - to invalidate the session at all
    - or any other way ?
    Thank you for any help,
    xtanto

    Taken from the release notes:
    Ctrl+N support The application user may experience incorrect behavior if they use Ctrl+N to open a new window from their application, press the refresh button on their browser toolbar (i.e. F5), copy and paste a URL for an
    ADF Faces app fromone window to another, or use the ADF Faces dialog framework to open new browser windows. If these usecases are critical to you, please set the following context parameter in your web.xml file.
    We expect to support the Ctrl+N use cases by default in a future release.

    <param-name>oracle.adf.view.rich.newWindowDetect.OPTIONS</param-name>

  • How to restrict customer records being displayed using 'sales_channel_type' criteria in customer search form at 11g?

    OS: Linux
    DB: 11.2.0.3
    ERP: 11g
    Hi There,
         I would like to create a new custom responsibility, which the responsibility is having access to Standard Customer Form (ARXCUDCI.fmb) , but I would like to make a restriction in the customer search form is that, everytime the responsibility user search by customer number, customer name, party name or what ever search field, I would like to limit to restrict further of searching criteria where SALES_CHANNEL_TYPE = 'RTL' is allowed to populate the customer records, there rest of customer records are not allowed to search out.
        This SALES_CHANNEL_TYPE column is from HZ_CUST_ACCOUNTS table.
        I have tried the Form Personalization already, but the customer searching form has too many fields for user to search, therefore form personalization will be putting all over the places in the form. Therefore I saw others recommended of doing "Custom DLL"...may I know for my scenario, how to I go about Customer DLL? or any other more effective solution?
       Appreciate if anyone can share your experience related to matter above.
    Regards,
    Lygine

    Hi Lygine,
    The personalization i sent you works in this way:
    -It does not matter which field you choose to enter the query.
    -If a record is found, when the form opens and the cursor hits the Customer Name field, the personalization looks for the content of the Sales Channel field.
    -If the content of this field is different from the 'RTL' string, the form Customers form (ARXCUDCI) is cleared.
    Independently from the field you fill to perform the query, is a record is found, the Customer Name field is the first the cursor hits when the form is opened.

  • Secondary Process Model

    The TestStand Reference Manual states on page A-4:
    "In addition to using a primary, or parent, process model file, you can use a secondary, or child, process model file to encapsulate specific functionality, such as report generation."
    A "secondary process model" file is also mentioned on page 10-3:
    "A primary process model file can directly call model callback sequences in a secondary process model file. At run time, if the client sequence file of the primary sequence file implements a callback defined in the secondary process model file, TestStand invokes the callback sequence in the client sequence file, even if the primary process model file does not define the callback. You must add a copy of the callback sequence to the primary model file for the callback to appear in the Sequence File Callbacks dialog box for the client sequence file."
    I cannot find any additional information on the secondary process model.
    Can anyone explain how a secondary process model would be used?
    Are there any examples using a secondary process model?
    Thanks!
    CLA, CTA
    Solved!
    Go to Solution.

    1. How does one create/designate a secondary/child process model?
    It appears this is done by creation of a callback sequence in a "child" sequence file AND the "parent sequence file".  Is this correct?
    To create a process model in general you would open a sequence file and go to Edit>>Sequence File Properties.  Then on the Advanced tab change the Type to Model.  For it to become a secondary/child process model you would make a sequence call to it from the primary process model.  For instance the SequentialModel.seq at one point makes a call to ProcessOTFStepResult in either of the Engine callbacks in there.  Then the ProcessOTFStepResult sequence makes a call to PutOneResultInReport (if you are using the reportgen_txt.seq).  Then the PutOneResultInReport sequence makes a call to ModifyReportEntry (which is a callback).  However, if I have a client sequence file I would like to intercept that result and do some modifications.  So I would override that callback.  But since ProcessOTFStepResult and PutOneResultInReport are not in the process model there needs to be a mechanism for me to override that from the client.  This is because reportgen_txt.seq has different behavior than reportgen_html.seq or reportgen_xml.seq.  So it doesn't make sense to put everything in the process model.  Otherwise, your PM would be ridiculously large.  But you also need to make a copy of the callback in the PM so the client can see it.
    2. Is the parent sequence file callback simply acting as a pointer to the child sequence file callback?  Yes and No.  It depends on if it's invoked in the secondary PM or in the primary PM.
    3. How many levels of "child process models" can one create?  Is it possible to create a "third process model"? I just tested this out and it looks like you can.  But you do not have to put the callback in your secondary one.  Just the third layer and primary PM.

  • Finding the name of my teststand sequence in the process model

    I would like to be able to find the file path and name of a teststand sequence in the process model. I have created a simple vi which will display this information when run in a sequence. If i insert the vi into the process model, the file path and name returned is that of the process model and not the sequence under exectution. Is there a way of extracting this information in the process model?

    Davepar -
    If you are executing in the process model you can use the following as a lookup string if you are in the root context "RunState.ProcessModelClient.Path" or "RunState.Root.RunState.ProcessModelClient.Path" if you are not in the root context.

  • How to strongly protect the step types from being modified by others?

    how to strongly protect the step types from being modified by others?

    Hi Jacky,
    You can make a property of a step uneditable by changing the property
    flags for the step.  First, you want to be able to view the hidden
    properties so that you can change the flags for these properties as
    well.  You do this by going to Configure>>Station Options
    and selecting the Preferences tab.  Check the box for Show Hidden
    Properties.  Once you have done this you can select the step type
    from the types palette.  In the window to the left, you can expand
    the tree for the type to see all the properties of that step. 
    Right click on the property that you do not want users to be able to
    edit, select Properties.  Then click the Advanced button. 
    Here you will see a list of the setable flags.  Check the box for
    PropFlag_NonEditable.  You can then do this for all the properties
    of the step that you do not want users to edit.

  • Best way to modify Sequential Process Model for report generation.

    I am using the Sequential Process Model in my application and the TestStand Reference Manual, (Figure A-1), clearly shows the following processing sequence:
    ...<part removed>
        Call the Test Sequence
        Display the UUT results
        Generate a Report
        Log Result to a Database
    ...<more removed>
    I want to generate the report BEFORE displaying the results to the operator, or at a minimum, I want to generate the report in parallel with displaying the results to the operator.  Currently, the problem I have is that when the test is done I have some automated scripts that take the data file and do some statistical processing on it, but the way the Sequential Process Model is set up, the test might finish but until the operator acknowledges the PASS/FAIL results display, the resulting file is never created.  It could be overnight, over the weekend, or several days before an operator comes back and says, "Oh that last test finished, I guess I can press the OK button!", but until they do, I get no data.  So I want the report generated no matter what, and right after the test finishes.
    Any ideas as to how that might be best accomplished?
    Thanks a billion -  Ski (noob)

    Ray,
    Is that new in 4.2 that the engine won't call a callback with nothing in it?  I just did it and it seemed to work fine.  I'm using 4.1.1 though.
    Ski,
    Maybe there is a better solution for what you want.  Are you using the SequentialModel?  What version of TS do you use?  Why does the report have to be written before the pass/fail banner displays?  The pass/fail banner gets displayed in the PostUUT callback.  Like Ray said if you just put that in your client sequence you won't see the banners.  However, I'm assuming there is more to this than just that.  I'm assuming you want to see the report because of your external analyzer that is gathering the statistical data.  And then based on that data you want to allow the user other options.  Is this correct? 
    If so then I would override the PostUUT callback and then use a different callback (possible the ProcessCleanup callback) to displaly the banners.  You could even do this without modifying the process model (which I always try to avoid).  Just override both the PostUUT and ProcessCleanup callbacks.  And then put code in the ProcessCleanup to behave like you need.
    Or if you want you can modify the process model and create a new callback lower in the process model.  Then have that new one do the post report analysis.
    Just some thoughts.

  • How to assure index is being used for Query

    Hi All,
    Indexed are best way to speedup the data retrieval process selectively.
    however i wanted to how to trace that weather index is being used in a particular query.

    2. Select a,b,c from tab1 where a>500 ;
    Will this query use index create from 1 ?
    Conceptually it should not because where as part contains only field A where as index is composit on field A and B.
