Trigger's execution hierarchy

HI,
EVERYONE;
I AM NEW TO DEVELOPER, SO PLZ HELP ME. I HAVE
CREATED A FORM WITH A DATABLOCK. I HAVE WRITTEN A
"WHEN_MOUSE_CLICK" TRIGGER ON FORM,BLOCK,ITEM LEVEL
ECAH HAVING EXECUTION-HIERARCHY PROPERTY TO "BEFORE"
WITH DIFFERENT MESSAGES.
WHEN FIRST TIME I RUN THIS FORM IT RUN OKY WITH DISPLAYING
ITEM MESSAGE > BLOCK MESSAGE > FORM MESSAGE. BUT WHEN AGAIN
WHEN I CLICK ON THE SAME ITEM WITHOUT CLOSING THE FORM THEN
THE ORDER OF MESSAGE IS DIFFERENT. THE ORDER IS:
FORM MESSAGE > ITEM MESSAGE > BLOCK MESSAGE
I WANT TO ASK WHY IT IS HAPPENING?

Hi,
I think there is some other problem at your side, may be something wrong in your code, as it is Ok, at my side. I tested it.

Execution Hierarchy of a Trigger at RunTime

Hello Everybody,
Does anybody know, how to get to know what is the execution hierarchy of a given trigger at run time ?
What is the built-in or any work around ?
John

Hierarchy is based on how and what triggers you are using, it can be many scenarious and there is no single answer. The best way for you to find, what fires after what on your form is to put debug messages with trigger name, trigger item/block in each trigger and see in what order messages get displayed at run time.

Execution hierarchy of firing for a trigger?

could you please tell me the execution heirarchy for trigger

e.g. when you have a WHEN-NEW-ITEM-INSTANCE :
if you create a trigger on item, block and form-level, then only the ITEM-Level will start. If you use the exec-hierarchy Override.
If all trigger use After, then the FORM, BLOCK and ITEM starts in that sequence.
If all trigger use Before, then the ITEM, BLOCK and FORM starts in that sequence.
the execution-hierarchy on FORM-Level is ignored, because there is no higher level than FORM

How to externally trigger the execution of TestStand with a start and abort button through a digital interface?

Hello,
I'm Currently evaluating TestStand as an alternative for an in-house developed Test Sequencer.
To start our own Test Sequencer we use a small box, connected to a DIO board. The box has a start button and an abort button. The box also has a pass, a fail and a running led.
The interface with this box is made via some digital lines of a PCI-DIO-96.
In our own Test Sequencer we have groups named Init, Run, Abort, Exit.
The Init group is executed at startup (only once). It is used to initialize all the HW and SW. -> I guess this is the Pre UUT Loop callback in TestStand.
The Exit group is only executed once at the end of the day when the application is terminated. It is used to free all the used hardware and cleanup all the resources. This probably is the Post UUT Loop Callback in TS.
When a product needs to be tested, the operator presses the "start" button which triggers our own Test Sequencer and the run and abort group are being executed (first the run group, afterwards the abort group).
When the product is being tested the "running led" of the little box lights up to indicate to the operator that the application is running. (only when the run and abort group are running)
The Run group has all the functional tests in it. (MainSequence)
The abort group is used to put everything back in it's original state after the test on this single product is done. (Post UUT)
When executing the tests and something goes wrong (operator gets stuck in a clamper, ...) the operator can still press the abort button and then the execution immediately jumps from the currently executing step in the run group to the first step of the abort group. So, when something goes wrong, immediately the abort group is called.
At the end of the run and abort group, if no errors occured, the "pass led" lights up. If one or more steps went wrong the "fail" led lights up.
This setup can also be used to test multiple product in parallel. At that time all the different parallel testers have such a small box which contains a "start" and "abort" button and a pass, fail and running led. (it is possible that they are all connected to the same PCI-DIO-96 board. )
My question:
Is it possible to do something similar like this in Teststand? If yes, is there an example available that shows me how to do this in TestStand? (externally trigger the execution of TestStand)
Typically, in the Init group (Pre UUT Loop) the digital interface box gets initialised.
In the Close group (Post UUT Loop) the digital interface box is taken out of scope.
Note: The PCI-DIO-96 board to which the digital interface box is connected will also be used in the rest of the developed application (MainSequence, ...)
What's really important for me is that I can create a process model that all the application developers in our organisation can use. I really don't want any of the application developers (limited software experience) to mess around in all the features of TestStand.
For them it's important that they just add the function DigitalInterfaceBoxInit () in the Pre UUT Loop Callback and the DigitalInterfaceBoxClose () in the Post UUT Loop Callback, and then everything works!
It is important that the appliation developers do not have to create any global variables, other functions, synchronisations, parallel sequences, ... in TestStand. All this needs to be done with a simple call to the DigitalInterfaceBoxInit function.
Thanks in advance for all the help!

Dennis-
Your application sounds very well suited to TestStand's abilities. I am also quite impressed with your knowledge of how TestStand's architecture is arranged when you are still just considering whether or not to use it.
I think that TestStand would work really well for you in this application. Like you mentioned it will provide you with a form of standardization for your application developers to work from. It also provides the flexibility for you to add your custom routines in many different places. TestStand also makes parallel and batch testing much easier in TS 2.0 so that you could develop one test for your product and execute different instances of it in parallel to test multiple products at once.
As for your specific question about how to c
ontrol TestStand using a DIO board. I think this is very feasible and should not be too difficult. Since TestStand provides you the ability to create a custom operator interface your operator interface could monitor the status of your DIO board and launch/abort executions based on the read values. Usually the executions are launched/aborted when a button on the GUI is pressed however, I do not see any thing different about basing the action on a DI signal vs a mouse click. I am sure your application is more involved than this high level description but from the sounds of it I think it is very possible to do with TestStand.
Based on my experience of building test systems with TestStand and your description of the application, I would feel very confident in using TestStand to achieve all the goals you mentioned. If you have further detailed questions on how one of your features might be implemented, feel free to contact one of our Application Engineers or email us at www.ni.com/ask
and we would be glad to help you.

Version Problem??

Hi,
I am using Form Builder 6.0.8.11.3 .
I have a problem with the Trigger Level Execution Hierarchy Property.
I have when-new-item-instance trigger set at Item level and at the block level.The Item level triger has it's execution hierarchy set to after.
But still the Item level trigger fires first and then the block level trigger fires whereas it shud be the other way round.
Is it a Version Bug or anything else??
Pls help
Alfred

We do have a fix in this area and it was for WTC to TUX6.5.
I believe this is a padding problem. I was expect if you send
101 bytes and tuxedo will get 104 byte. Sending 100 bytes and tuxedo
receives 101, 102, or 103 bytes is strange to me. Anyway, please contact
with BEA customer support to create a CR and a test case for this. At
this moment, I do not know where is the problem. It could be in tuxedo
side.
Thanks

Are you saying that you send 100 bytes, but when the server receives
the message,
the TPSVCINFO->len value is 101?Right! sometimes it may be 102 or 103. and befor tpcall, the length of bytes is
still 100.
my code:
data = new TypedCArray(baInput.length);
// for example: length = 100
data.carray = baInput;
// my data, byte[] type
System.out.println("data carray length:"+ data.carray.length);
// length =100
System.out.println("data length:"+ data.sendSize);
// length =100
try {
reply = tc.tpcall(svcName, data, 0);
} catch (TPReplyException tre) {
throw tre;
however, the tuxedo server get 101(102 or 103) bytes.
And if the tuxedo server reply 100 bytes, i get 100!!

How to override trigger in Oracle Apps

If i have W-V-I trigger at form level, block level and at item level how can i override the triggers above item level. can anybody tell me how to do this Apps ?

Hi,
You just need to change the property 'Execution Hierarchy' on the item trigger to 'Override'. That should override the trigger at block and form level.
Hope it helps.

Is it possible to change trigger firing sequence by program?

Hi,
I would like to know if there is a command like set_item_property or set_block_property or set_lov_property which can allow to change by program a trigger firing sequence. I do not find any, so i think i have to do it manually in property palette of the trigger. Thanks for your answer.

Thx
To change Execution Hierarchy of a trigger, we go into Property palette of that trigger to change this property, i want to know if it is possible to change this property by program without need to go into Property palette of that trigger, EXECUTE_TRIGGER executes an indicated trigger but how to change Execution Hierarchy (for example set_lov_property sets the given LOV property for the given LOV, we use set_lov_property in the program and do not need to go into property palette of this lov), hope you understand what i would like to do. thanks for your help.

Why Module level trigger contains "WHEN-CHECKBOX-CHANGED" trigger in Forms 6i?

Hi,
Why Module level trigger contains triggers like "WHEN-CHECKBOX-CHANGED", "WHEN-BUTTON-PRESSED" etc.? "WHEN-CHECKBOX-CHANGED" trigger is present in CheckBox & "WHEN-BUTTON-PRESSED" trigger in Button. Then why these triggers are also presnt in Module?
Can anyone please clarify my doubt?

There's a lot of triggers that are present at different "scopes". Like they exist at the item level, the block level,
the module level...
The idea is if you have an action that should only occur at that one single item it can do in the item trigger. If
it's for all of them on the block, in the block level trigger. If for all of them ever, at the module level.
For example suppose you wanted it to do a next_item after the trigger executed you can put that logic in the module
level trigger. A key thing to notice here is the trigger hierarchy. That is essential to know about.
Right click on one of these triggers in the object navigator. The execution hierarchy is override, before and after.
since each of these levels of the same trigger has this execution hierarchy this is, well, potentially not easy to
understand what is going to happen. I would typically have a per-item trigger be before and a higher level trigger
be after.
And this execution hierarchy thing is something I'd love to see enhanced in the gui. I wish it was a lot easier to see
what the execution hierarchy is when editing a trigger text. I wish one could see and modify the execution hierarchy on the
same screen as the trigger text and what would be really great is some way to tell how the trigger hierarchy will sort out
at run time. For example if one is looking at an item level trigger it would be fabulous to know that as is, that trigger will be
overridden by a higher level trigger and so on. Or vice versa if one is looking at a block level or form level trigger that it is
overridden by a lower level trigger, or it will execute before or after some other trigger. I don't know what is defined to happen
with various levels of triggers that have the same execution hierarchy. Like suppose they are all override,before,after.. then
what happens? It'd be good to know.

Oracle Forms 9i
Hai All
In forms when_button_trigger is a block level or item level trigger and give me some
Form level trigger,block level trigger, item level trigger
Thanks & Regards
Srikkanth.M

in forms u have 3 level triggers
Level triggers basically defines the scope of the trigger
FORM LEVEL : can see all blocks and items in the block
Block Level : can see only items in its block
Item level: Works on only item to whom it is attached.
IF U HAVE SAME WHEN-BUTTON-PRESSED TRIGGER on all levels (FORM, BLOCK, ITEM) then first ITEm level trigger will fire then block then Form
but u can change the execution of trigger in TRIGGER's property EXECUTION HIERARCHY to Before/after or Overide
Hope it helps
Plz mark it correct or helpful

Force Form to Execute builtin trigger at form level

Hi,
I have form 10g R2 I put PRE-UPDATE trigger at block level and Form level but I when I update a record it executes only block level update trigger, I want to execute both builtin at block as well as form level, is there a way.
Thanks and Regards, Khawar.
Message was edited by:
S. Khawar

I created a test form (Oracle Forms 10g r1) that hits the EMP table in the SCOTT schema. In the form, I added a Pre-Update trigger at the Form and Block level. With the "Execution Hierarchy" (EH) left at the default Override, saving my form caused only the Block Pre-Update trigger to fire. Changing the Block EH to Before and the Form EH to After caused the Block Pre-Update to fire first followed by the Form Pre-Update. I then changed the Form EH to Before and the Block EH to After and tried it again. This time, the Save caused the Form Pre-Update to fire first and the Block Pre-Update to fire second. Therefore, S.Khawar, depending on which Pre-Update trigger you want to fire first, I suggest you set the Execution Hierarchy accordingly.
That was an fun little exercise. I've had this discussion with people before, but never took the time to throw together a test case to confirm what really happens in a Form. Steve - thanks for raising the question! :-)

Remotely trigger tests in OTM?

Hi there,
All my searching is just returning results regarding database triggers, so I'll just ask here... Is it possible to remotely trigger test execution in Oracle Test Manager? I know I can schedule tests for a specific time/dates/etc., but I was hoping to get a step further. For example, we will have an automated process in Hudson that builds the product and then deploys it after there's new code pushed into Mercurial, is it possible to have tests get triggered or kicked off in OTM other than manually or time-based?
Thanks,
-Troy

Getting the test to run from the command line was really simple with Appendix A, and it created results saved results to disk... But those results aren't showing up in OTM. Is there a way to import results into OTM? The end goal is to be able to run the tests housed in OTM to take advantage of the reporting capabilities built-in, whenever there is a successful build of our product.
Thanks,
-Troy

Workflow; Trigger to execute IDOC matmas update

Hi
I do not know workflow at all. Is is possible to trigger a execution of an program using workflow as soon as there is a create/change of an material on the Materials master?
Message was edited by: Giovanni Baumann

Hi James
Thanks for your reply.
Your suggestion is as good as updating the dimension manual in Dimension excel sheet & processing. This processes will update the new data in mbr table . So in this approach following two steps involves
Step-1 u2013 Customer fills temp table or customer update dimension manually & processes it. Both the action will trigger package
Step-2 u2013 Data also need to be updated in data source i.e flat file. This task is performed by ETL team
Only when both of these task are performed that data source & BPC will in sync.
But what I want is only one step i.e. Step 2. This mean that when the data changes, the ETL team make necessary change in data source & this change should trigger the package. To do this I need to write cmd command to trigger the package.
I hope my situation is more clear to you know. Kindly let me know if you have any solution.
Regards,
Rahul
