Registered Object Question

Hi, I have changed an object and supplied the object key successfully. I can now successfully edit the object. But, when I sign on to another machine with the same profile I get prompted for the object key again.
Any ideas why this would be? Any idea what table holds the registration information?
Thanks!

When you say "another machine" are you referring to a different instance of SAP? If this is the case, when you register an object, you are registering the object for that instance of SAP only. Now, I believe that you can use the same key to access the same object in two different systems. In our landscape, we get the key for the object in our development system, make the change, then send it on to production. We only enter the key one time.

External transaction control and ability to find new registered objects

Hello, We are using Toplink with external transaction control and have a process inserting a complex hierarchy of objects. During the process we either do a registerObject or deepmergeClone depending on if the instance is already in the db. With external transaction control the registerObject does not actually do the commit to db until the global transaction (Container) issues the commit. Unfortunately we end up doing creating multiple instances of same objects ( because the assumption that registerObject would have written the row to the db ) with the same keys and when the container issues the commit we end up with duplicate key violation. Is there a way to find out if an object with a particular key is already registered?

This sounds like the kind of question that can only be answered with a whiteboard and a good review of your architecture.
In general, there should be no problem registering objects multiple times. I.e.,
x = some object
x1 = uow.registerObject(x);
Then x1==uow.registerObject(x), and x1==uow.registerObject(x1), etc. When you register an object with the UOW, based on PK it'll always return that same one.
Do you have multiple units of work on the go? (that may explain this behavior).
In any case, I think the real problem here is that you're somehow registering objects that are no longer cached. I.e., some object is serialized or rebuilt and then registered after it's gone from the cache. By default, TopLink determines if an object is new or existing (to determine INSERT vs UPDATE) by hitting the cache. You can change this default behavior in the Mapping Workbench, open the advanced property for "Identity" and change existence checking to "check database". Although, this can be a slow and tedious process to have to keep hitting the DB.
A little trick I use sometimes is to take advantage of the "readObject" API that will read the object from the databaes if it's not already in cache, and just return it from cache if it is in cache. Check out the UOW primer at http://otn.oracle.com/products/ias/toplink/index.html for more info, but the jist is that I would do this if I were you:
x = some object that you're not sure is cached and you want to register in UOW;
x' = uow.readObject(x);
IF the object was in cache, you'd get back a working copy, nice and fast. IF it's not in cache, you hit the database, it goes in cache, and you get your working copy. Now you don't have to change the existence checking option which could slow everything down.

Registered objects with Unit of work

Hi,
I am using the following code for persisting some data to the database. I register the following objects with the UOW obtained. If there is any exception with the business rules method(shown below) , the code uow.commit() is never invoked.
My question here is what happens the registered objects in that uow if commit is never invoked.
Any help will be appreciated.
Thanks
Priya
node=(DeviceNode) uow.registerObject(node);
station=(Station)uow.registerObject(station);
user=(User)uow.registerObject(user);
//Call a method to do some businees rules check
startWork(node,station,user);
uow.commit;

It depends on how you set things up. If you are managing the connection directly via Toplink (no pooling or containers or transactions), then if you dont commit, it doesnt save. If you are using JTS, registering the object will save it to the database barring any unchecked exceptions.

Remote register object

The UnicastRemoteObject can register OBJECT by the export method. Is it feasible to register the object remotely to a seperate machine?
e.g.
Machine A register object A at Machine B
Machine C invoke RMI on Machine B and use object A
If it works, i can eliminate the RMI from Machine B to Machine A.
Otherwise, i need to invoke twice of RMI, C --> B then B --> A since we don't want to run C-->A directly.

The UnicastRemoteObject can register OBJECT by the
export method.No it can't. What it does is to export it from the current machine.
Is it feasible to register the object
remotely to a seperate machine?The question makes no sense as stated given the terminology error.
Machine A register object A at Machine B
Machine C invoke RMI on Machine B and use object ATo put it correctly, once a remote JVM B has acquired a remote reference to a remote object exported from A, it can pass it to another JVM in the same or another host, say C, and JVM C will then communiate directly with the original host from which A was exported when calling methods on A, without involving B in the exchange.

Registering a child of registered object goes into endless recursion

Hi
Looks like we have found another bug in toplink.
test scenario: object A have a indirection relation 1:1 with object B
Lets register object A. Everything works fine. Lets register that cloneA1 again. It is fine again ( registration returns same object).
Now lets ask cloneA1 for related object B : cloneA1.getB(). Works fine. And we know that it retirn registeres object cloneB1. Now - lets imagine that developer made a mistake (usual thing is this unperfect world) and trying to register cloneB1 again. Instead of silently returning same object instance cloneB1, toplink in going into some endless recursion which ends up with StackOverflowError:
Received execption: java.lang.reflect.InvocationTargetException
java.lang.reflect.InvocationTargetException: java.lang.StackOverflowError

The mapping of A and B is as follows:
Both A and B are interfaces of concrete classes
mapped with Interface Alias:
Aimpl implements A
Bimpl implements B
The attribute mappings are:
Bimpl.as is a OneToMany collection of A (bidirectional to Aimpl.b)
and using Transparent Indirection with IndirectList
Aimpl.b is the OneToOne "owner" B (bidirectional to Bimpl.as)
Aimpl.b OneToOneMapping to switched to ProxyIndirection
upon startup.
Application code works exclusively with A and B and gets
concrete instances from a factory.
There's much more to the mapping, but that seems to be all
the bits related to this problem.

Objective question book for certification

Hi,
I was preparing for my first level certification CLAD. I wanted to know if there is any book on the objective questions . I have already cleared the fundamental test at ni.com. I am looking for more practise.
Anyone who has given the test or plan to give one, please post some ways of preparing for the exam.
Also how hard it is ?
Any special tips for 2006 exam?
Any help would be greatly appreciated.
I am preparing for the exam by reading basic I and Basic II books.
I have given couple of fundamental tests on the NI website.
Also I keep reading and answering NI discussion posts to check on my knowledge about Labview.
Any other material that would be helpful in clearing the exam.
Also according to certification FAQs the passing percentage is 70% whereas the fundamental test results will declare you Pass only when you score more than 80 %.
What is actually the passing percentage for the exam?
Regards
CLAD
Using Labview 5.1,6.1,7.1.8.0

Passing the test myself you are required by NI not to disclose any information so where do I start? If you have been using LabVIEW for at least a year you should be fine. The test is constantly changing so even if I were to tell you what to study it may be all different. I guess the best advice would be able to inspect code without running it and know what LabVIEW result will be. If you are comfortable with loops and shift registers and understand what the result of the code wold be then you should do OK. I know the questions was what books would help the most. I just looked at the LabVIEW manual and managed to do fine. Another tip would to be study the things that you typically don't use or how it is implemented. A book will help you to a point but you need to be comfortable with LabVIEW and its wide functionality.
Does this help?

Activex Object Question

Hi,
I posted this question by mistake in the LabVIEW/CVI fourms, so I am reposting it here. I have a question about how LabVIEW "sees" activex controls. I have a dll, which displays createable objects in the activex menu. LabVIEW sees the type library name and I can create methods and property nodes. Now, when I load the same dll into VB 2008, I get the self-registration error, eventhough the dll was manually registered using regsrv32. What is LabVIEW doing to be able to "see" the activex controls inside the dll?

Hey shivels,
The dll you are using is working properly in LabVIEW? It seems like the problem is less with LabVIEW and more with VB2008. It might be more helpful to post your question in a forum for VB2008 to figure out why it is not working. The lowest level code that LabVIEW is using to interface with ActiveX is not information that is really make available.
Hope this helps.

      old_BP [nbCombis] = BP;
      old_MP [nbCombis] = MP;

I don't understand the lower thing...

ADF View objects question

Hello,
I created a view object (which bases on an entity object) that I'd like to use for searching for records in a table called "CARS". Cars will be searched by names. I also have a JSP page for adding cars (administration functionality).
The situation is as follows:
1. I go to the page for adding cars and click "Submit" (which only submits data without committing to the database).
2. Then I have validation errors (which is ok because some fields are mandatory).
3. I search for cars by name.
The funny part is that if I search for cars with given names, I get those cars AND I get the empty row with this new car I'd tried to add just a moment ago. It's definitely not yet in the database and the name of this car is not set (so it shouldn't match with the name I'm searching for).
My question is: why is it happening and what should I do to get the rows created but not yet committed not appear in the search results?
I tried to use clearCache() method of ViewObjectImpl but the result is still the same.
Please help because I desperately need this for my diploma project.
Thanks,
Anna

I run: "java -Djbo.viewlink.consistent=false -jar oc4j.jar" and I still get new rows. I'm using OC4J 10g (9.0.4.0.0) standalone that comes with JDeveloper 10g (9.0.5.2) on Linux.
And about that Create pages: I mean I click on a link "New something" 3 times (for example). I don't use the browser back button because I have my menu on each page. In this case I'm just curious if it's possible to somehow "overwrite" previous "new" rows with the most recent one.
I thought I would need that but now I know I need something else.
Imagine such a situation:
1. A user wants to create a new row or update an existing one.
2. They start filling the form and submit it (in my case it's committing at the same time)
3. During validation it turns out that some required values are missing so the user has to enter them.
4. At this point the user leaves the input form and decides to add or update a different row.
5. The user enters all the required values and this time validation would succeed. However, because of points 2. and 3. it does not.
Now my question is: how can I make ADF somehow "forget" about the row inserted/updated in point 2. I know that ADF validates all new/changed rows at a time. But I would like to change that behavior so that it would validate only the row changed/created most recently.
Thanks,
Anna

Using ChaRM to register objects in Marketplace

Hello,
We want to control what changes are done to SAP standard workbench objects, using ChaRM, so that for example every time a program needs to be registered to make customer modifications in the marketplace we can do it using a ticket from ChaRM. Then we can have an approval process and a total traceability.
Is that possible? Is there any alternative way to have that controlled in Solution Manager?
I appreciate your comments.
Regards
Esteban

Hi Prakhar,
Thanks for your answer. However the issue is a bit different. Customer found that they want to make a modification in a standard code because of business needs. So, they need to access to the marketplace to register that object. No incident was created in Service Desk, no notes from SAP. We want to have a Change Request and a Change Document to control the modifications and registration of this object. However I did not found any action in ChaRM Change Document that allows me to access marketplace and keep track of this registration in the change document.
Do you have any idea?
Many thanks
Esteban

Using a registered object outside a UnitOfWork

We are constructing a multi-tiered application using TopLink 4.6. The Model and Controller are in different JARs but are part of the same EAR. Data objects mapped in TopLink are sent by the Model to the Controller. The Controller may modify these objects locally, and send them back to the Model for persisting.
When the Controller makes a request for a data object to the Model, the Model does the following -
1. Gets the object from the TopLink cache through a query
2. Gets a UnitOfWork
3. Registers the object with the UnitOfWork to get the clone
4. Releases the UnitOfWork
5. Returns the clone to the Controller
I am registering the object with a UnitOfWork, even though I am not modifying it in that UnitOfWork.
I have to do this because the object model is very complicated. The Controller needs access to the root object, and also all of its nested parts. Using this technique, I retain the benefit of Indirection. The other option is to use a ObjectCopyingPolicy, but that is expensive as the Model is forced to do a cascadeAll copy. Also, I cannot send back the original object returned by the query because this object comes from the cache, and the Controller could end up modifying it, thus causing possible data inconsistency.
After the Controller sends back the modified object, the Model now does the following -
1. Check the incoming object and perform business validations
2. Get a UnitOfWork
3. Do a deepMergeClone on the UnitOfWork to save the object.
4. Commit or release the UnitOfWork
This seems to work without any problems. Will this have any other repercussions? The object is initially obtained through a different UnitOfWork, and is saved using a different UnitOfWork.
Is there a better way of handling this situation?
Thanks

Hi,
The key here is that the object is cloned (copied) and the clone (copy) is returned to the client.
The client then makes the changes to the copy (the original is still in the session cache and has not changed)
When the object is register, TopLink does a look-up, using the copy Object, in the session to find the original object, it then makes a clone of the original object.
You now have three copies of the same object. The Original Object (no changes), the clone of the Original Object (no changes yet), and the copy Object (with client changes).
The next step merges the Original Object Clone (without changes) and the copy Object Clone (with changes).
Now your system has two copies, The Original Object (no changes) and the clone Object (with changes).
Now on commit, TopLink compares the Original with the Clone and updates the DB.
