Ora 02290 when using qms_transaction_mgt and autonomous transactions

Hi all,
I'm using the qms procedures:
qms_transaction_mgt for openeing and closing transactions.
Somewhere in my procedure when the transaction is opened i call another procedure which contains a autonomous transaction.
The next time qms_transaction_mgt.close_transaction is called i get an ORA-02290: check constraint (HST65.QMS_NEED_TO_CLOSE_TRANSACTION) violated
When i debug the qms_transaction_mgt.close transaction the g_current_trans_id variable is empty, which indicates the transaction is allready closed.
When i remove the pragma autonomous_transaction statement and the commit statement from the procedure i call, the problem is resolved.
Version information:
Designer 9.0.2 with a with a Oracle 9i 9.2 database and Headstart 9i.
Does anybody know how i can resolve this or if this is a bug and how to fix it?
Thanks,
Yvon

Ian, Yvon,
It is unfortunately a know restriction that the CDM RuleFrame component of both Headstart for Designer 6i and Headstart for Designer 9i doesn't work in combination with autonomous transactions.
The reason is that the RuleFrame administration relies on information stored in 1. pl/sql package variables and 2. database tables. Using autonomous transactions (that involve CDM RuleFramed DML) causes this information to dissynchronize.
A year ago I investigated the possibilities to make autonomous transactions possible with RuleFrame but unfortunately this is fundamental problem: RuleFrame wants to combine multiple DML-actions into one logical transaction (gards this with the "need_to_close_transaction" constraint), while autonomous transactions intend to to the opposite: commit a part of a transaction while the rest of the transaction still is posted/not committed.
There is one exception: if you call an atonomous procedure that does DML on a non-ruleframe-enabled table (no TAPI triggers that intend to open/close the transaction, no CAPI etc), everything functions.
Problem explanation:
====================
1. Outer transaction is opened (by front end or TAPI triggers of first DML)
2. DML takes place
3. Autonomous transaction-procedure is called
4. Auto-transaction again tries (and succeeds!) to open the transaction, it doesn't see that the transaction is opened (db table qms_transactions is empty for the autonomous transaction on query)
5. DML within auto-transaction is posted
6. Auto-transaction closes transaction
7. Auto-transaction is committed
8. Outer transaction thinks the transaction is already closed, because the auto-transaction cleaned out the package variables when it closed the transaction.
9. Commit of the outer transaction fails as the deferred check constraint need_to_close_transaction avoids this to happen (rollback takes place because of this violation).
Hope this helps
Kind Regards

Mark is correct, you will need to contact support. ORA-600 errors usually require you to patch the database or at least use a workaround to avoid the error.

How to use DataSource and External transaction in 9ias?

I'm working on a project that the application server needs to connect to over 100 databases.
I'd like to use connection pooling and external transaction service defined in OC4J's Datasources.
I wonder if anyone has an example of using datasource and external transaction service for OC4J.
Right now, I export toplink project to a java source and do the initialization there manually but I don't know how to use Datasource to get connections and how to use the external transaction service in the java code for OC4J.
I really appreciate you help.
Wei

Here is a fill in the blank example on how you could set this up through code:
Project project = new MyProject();
// alternatively, use the XMLProjectReader
server = project.createServerSession();
server.getLogin().useExternalConnectionPooling();
server.getLogin().setConnector(new JNDIConnector(new javax.naming.InitialContext(), "jdbc/DataSourceName"));
// the next line depends on the type of driver you want to use.
server.getLogin().useOracleThinJDBCDriver();
server.getLogin().useOracle();
server.getLogin().setUserName("username");
server.getLogin().setPassword("password");
server.getLogin().useExternalTransactionController();
server.setExternalTransactionController(new Oracle9iJTSExternalTransactionController());
server.logMessages();
server.login();

How do I close a JInternalFrame when using subclasses and a separate cla...

The heading should be: How do I close a JInternalFrame when using subclasses and a separate class for the actionListener?
I have just created a JInternalFrame appclication and now I want to structure up my code. I have a Superclass that contains the usual settings for the two JInternalFrame:s, and the two subclasses with frame specific information. Both the JInternalFrames use the same OK button. I want to have the actionListener outside the classes to avoid repetition of code. But the dispose()-function does not work properly, it does not close the opened JInternalFrame. What�s wrong?
class Superclass extends JFrame
     JButton b= new JButton("ok");
     Superclass()
class Subclass1 extends Superclass
     Subclass1 ()
          add(ok);
       ok.addActionListener(new Listener());
class Subclass2 extends Superclass
     Subclass2 ()
          add(ok);
       ok.addActionListener(new Listener());
class Listener extends Superclass implements ActionListener
     public void actionPerformed(ActionEvent e)
               dispose();
}How do I controll in the Listener class that the button in Subclass1 is beeing pressed?

First of all I think I misunderstood your question. You said you had two internal frames, so I thought you wanted to close the internal frame.
It now looks to me like you want to close the entire JFrame, which makes the code even a little easier. Something like:
JComponent component = (JComponent)event.getSource();
JFrame frame = (JFrame)SwingUtilities.windowForComponent( component );
frame.dispose();
Ok, I will make a try:
public static Container getAncestorOfClass(Class c, Component comp)
w.getAncestorOfClass(w, this); Fiirst you need to learn the basics of reading the API.
"getAncestorOfClass()" is a static method. That means you don't use a variable to invoke the method. You use the class itself.
"w" is a variable, which is a JFrame, but that is not what the first parameter should be. The first parameter is a "Class".
"this" will refer to your Listener class, but you need the Component that generated the ActionEvent.
When I thought you wanted to close an internal frame then the code would have been something like:
JComponent component = (JComponent)event.getSource();
Container container = SwingUtilities.getAncesterOfClass( JInternalFrame.class, component );
JInternalFrame internalFrame = (JInternalFrame)container;
internalFrame.invokeSomeMethodHere();If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)", that demonstrates the incorrect behaviour.

My photos are sharp but become soft when used in and IDVD slide show.

My photos are sharp but become soft when used in and IDVD slide show. How can I prevent this from happining??

Hi,
I suggest that you try unchecking both of the crop options - landscape & portrait.
To re-create your situation, I had to check the crop for landscape pictures option.
I prefer to have control over any cropping so I tend to crop each image first before creating the slide show.

Thanks Jon. I tried all of those solutions before posting. Same problem. It seems that the problem is tied to DWCC. Do not have the problem when using DW6 on Win8.1. When running DWCC on a Win7 pc, we get the same error message. When running DW6 on Win 7, f&c works fine. It seems to be a bug in DWCC. DWCC works flawlessly on our Macs.
The same steps apply to DWCC, you just need to choose the CC folders rather than the DWCS4-6 versions that the page talks about. The layout of CC's folders hasn't changed from the older versions which is why, I think, Adobe hasn't updated the troubleshooting page as of yet.
As Nancy mentions, a 38,500 page site is sort of ridiculously large for a static website, that could be part of the problem, but your response quoted above leads me to think you may have tried the troubleshooting steps in the wrong version of the program. Could you confirm that?

TS3742 I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto.

I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto. I have to power off my system to get it running again. Any suggestions on what I can do to address this situation.

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these procedures don't solve the problems.
Hope this helps

Building executables when using LV and MATRIXx

Hi!
With respect to Building executables when using LV and MATRIXx, I need clarification on following:
1) Pre-requisites to use MATRIXx? We have LV 7.1 FDS with application builder.
2) Licensing scheme? We would like to have MATRIX on 3 development stations.
3) Can we build stand alone executables when using MATRIXx with LV?
4) Do we need to purchase any addon to achieve (3) ?
Thanks,
Gurdas

Hello Gurdas,
Before I answer your questions, I am curious to know what you have in mind for the stand alone executables you are interested in building. It may help me to know a little more detail about your plans. Depending on your application, some of these answers may or may not be applicable. In any case, here are answers to your questions:
1) There are no prerequisites for using MATRIXx. LabVIEW is not required. However, with LabVIEW FDS, you do have an Xmath Script node located in the Functions > All Functions > Analyze > Mathematics > Formula palette. This node can be used to call Xmath scripts from LabVIEW.
Note: To use the Xmath Script node successfully, you will want to install LabVIEW 7.1.1 Maintenance Release. Refer to KnowledgeBase 300A6NDT: How Can I Resolve MATLAB and Xmath Script Node Issues in LabVIEW?
2) There are two licensing options for MATRIXx: node-locked and floating (concurrent). A node-locked license is restricted to a specific node and can be installed and used on that single computer. A floating (concurrent) license allows use of the product by a specified number of concurrent users on any computer on a local area network that includes a server running a single license manager. For more information, follow the link to the MATRIXx Price List from Products and Services: MATRIXx.
3) There are two ways you might build executables when using MATRIXx and LabVIEW. One way uses a component of MATRIXx to automatically generate C code. AutoCode is a component of MATRIXx that allows the user to turn system models into C code. This C code can then be compiled into an EXE or DLL. If built into a DLL, LabVIEW can be used to call the DLL. A more thorough explanation of this is provided in Developer Zone Tutorial: Running MATRIXx SystemBuild Models in LabVIEW/LabVIEW Real-Time.
Another way that may work is to build an executable from a LabVIEW VI that uses an Xmath Script Node. Any target machine running this executable would need to have Xmath and the LabVIEW Run-Time Engine installed.
4) No other add-ons are needed for (3). Do be sure to refer to the note following the answer to (1).
Regards,
Eric M.

Photoshop CC. Colour selection not working when using alt and brush.

Hi, Photoshop CC. Windows 8.1 64 bit. Colour selection not working when using alt and brush. I have tried rebooting and other things like closing swatch panel etc.
The alt key is otherwise OK. It's not the recent upgrade from Win 8 to 8.1 (5 days ago) because the colour selection facility was working yesterday. Any ideas.

I'd say things sound desperate enough to try resetting Preferences
Reset Preferences
Windows — Hold down Shift Ctrl Alt immediately after starting Photoshop
Mac — Hold down Shift Cmd Opt immediately after starting Photoshop
If that fails, we need to know your operating system?
Do you have a full CC subscription, or by apps do you mean Photoshop, Bridge and Lightroom?
Another other information that might pertain ?

Thank you so much wchp, this is brilliant. I have had this annoying problem for a long time. I eventually rang Mac support, they did not know how to fix the problem as you have suggested so they instigated many hardware replacements which eventually left my iMac severely crippled. They eventually replaced it with the latest model. But I spent two months working with a disabled computer which really interfere with my work.
Your solution appears to have solved my problem, at least so far, but I am hopeful that it is a permanent fix. I hope that your suggestions are taken up by Apple support. This may solve many users problems and avoid Apple making expensive fixes that don't actually work.
I thought that the new iMac would not have the 'Wake up from sleep by painting in the login window' problem but it did, this really annoyed me. Anyway now the problem appears to be solved, it's not I will repost and keep working on it. Thanks again.
