Need to trace the application module

Hi,
Here i am running a module from EBS suite which taking time and DB cpu time get higher and it is pl/sql packages which creating lot of sessions So i can not enable the 10046 trace at session level or database level So please provide me ways to trace that .
Thanks
Puneet

If you are able to initiate some changes in the code of the procedure let the developer put in dbms_application_info. They can set up module and action with this call.
And you can use dbms_monitor to trace only the mentioned actions or modules. This way you can trace the code you want.
create or replace procedure procedure_to_trace as
begin
dbms_application_info(module_name=>'procedure_to_trace',action_name='action_starts_here');
dbms_application_info(null,null);
end procedure_to_trace;
/If this is set up in the procedure or package or whatever, you can do the following from outsite via sql
SQL>exec DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE(module_name=>'procedure_to_trace',action_name=>'action_starts_here',waits=>true,binds=>true);Now the tracing will start with the right point and stop when module or action is unset.

Problem releasing the application module after upgrade to 11.1.1.2

We have recently upgraded from JDeveloper 11.1.1.1 to 11.1.1.2.
In the "tearDown()" method in our Unit Tests, the Application Module is realeased using:
private ApplicationModule am;
Configuration.releaseRootApplicationModule(am, true);
Alter the upgrade, this produces the following error:
oracle.jbo.JboException: JBO-33025: Failed to release application module MapServiceGlobal. Cookie handle not found.
Please Help.
FYI - this is the code that is used to create the application module:
Hashtable env = new Hashtable(2);
env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
try
InitialContext ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(rootAM);
am = home.create();
catch (NamingException nex)
/* Handle the error here if you don't find it */
throw new NamingException("Application Module naming exception " + rootAM + " : " + nex.getMessage());
/* Connect the AM to a database connection */
am.getTransaction().connect(jdbcConnectionURL);
* Set the bundled exception mode so that exceptions are thrown in the
* same way as when we're running in the web application.
am.getTransaction().setBundledExceptionMode(true);
Thanks,

Hi,
I used OCEP 10.3.0.0 and upgraded the wlevs30 domain to PS6(11.1.1.7.0). and it worked without such error.
My experience is:
1) in OCEP 10.3.0.0 it needs not to add the security groups in atnstore.txt
2) you need to add <scratch-directory/> for Jetty in server's config.xml otherwise you will see the visualizer takes a long time to get up on Windows

Helper Class = oracle.jbo.common.remote.corba.RemoteApplicationModuleHomeHelper
The Application Module conatians an entity object and a view object for Dept Table in schema jd(Username -jd, Password -jd).

Moneesh,
I believe there is a problem with the way you set the variable theAMDefName. It should be:
String theAMDefName = freshJBO.FreshJBOModule";
Then you need to reinstate the line you commented out, to set the application path (but remove the trailing / from the path, as shown):
env.put(JboContext.APPLICATION_PATH, "test/jd");
If that doesn't work, and for future reference, I suggest testing your deployed application module from the Business Component Browser (aka the tester) before trying your hand-coded client. Start the tester, select Oracle8i as the middle tier server type, make sure the other information in the connect window is correct, then click Connect.
Good luck

How to get the application module instance in backing bean.

This is Ramesh, I am new to JDeveloper world.
In my current application I have change password screen which allows user to change there password.
Here this is a pop-up page. Here I don't have the view object and pagadef for this changepassword.jspx file.
My aim is to call the Application Module method which takes the user name, old password and new password.
In backing bean I am trying to call this method by using
MyProjAM obj = _binding.getDataControl().getApplicationModule(); //throw null pointer exception.
_binding is the object of DCBindingContainer.
( I have created the parameter called "binding" as my managed bean property and values as #{binding})
But the above line is throwing the NullPointerException.
Could you please help me to come out of this problem.
Thanks and Regards,
Ramesh Biradar.

If your page has no page definition, then #{bindings} will be null during the request for that page.
If you need your page to invoke a data control method when you press a button, the simplest (and declarative) way is publish your AM method on the AM's client interface, then drop the method as a button from the data control palette onto your page. You don't even need a backing bean to accomplish this.
That said, you can refer to a data control in a backing bean using the expression #{data.[i]YourAppModuleNameDataControl.dataProvider}
So, assuming you have a helper method like this:
public static Object EL(String expression) {
    FacesContext ctx = getFacesContext();
    Application app = ctx.getApplication();
    ValueBinding bind = app.createValueBinding(expression);
    return bind.getValue(ctx);
}and assuming that your application module is named SRService
and assuming that you have correctly nominated any Application Module custom methods as being available to clients by selecting them on the "Client Interface" panel of the application module editor, then in a backing bean you can acquire an instance.
Then, the ADF design time will have automatically generated you a custom AM client interface named SRService and you can reference that service interface in your backing bean by using code like this:
        SRService svc = (SRService)EL("#{data.SRService.dataProvider}");
        svc.yourCustomMethod(your,args);

Howto stop the application module from using a DB

Hello,
Maybe and unusual question, but is there a way to stop the application module from connect to a DB? I know its purpose is to do so. But currently we are using ‘stub’ views and entities.
In the executequery and dodml we wrote our own code to access data from webservices.
We did this because we are also using JHeadStart which requires BC.
It all works fine, but the application module needs a valid connection to a DB, although it will never query anything there.
So is there a method which I can overwrite to make the application module think its connected to the DB but it actually isn’t?
A second problem is most likely its state table.

Example #96 on my blog does this. It might have some useful clues.

Question about the Application Module in bc4j

Hi all,
I've been playing with JDeveloper9i for a little ovar a week only and have been trying to get access to a BC4J View Object in order to execute a runtime specific query on it, by passing 2 user input values to the object, and setting the WHERE clause by a call to the setWhereClause() method on the View Object. The only way i could come across to get hold of the View Object was to create an Application Object (in this case its called Bc4jModule) and then to use a call to a custom method in the Application Module Implementation which i created and set to be a Client Method.
The code is as follows:
In the Application Module (Bc4jModuleImpl)
public int authenticateUser(String strLogin, String strP_Word)
getUsersView().setWhereClause(" LOGIN='" + strLogin + "' AND P_WORD='" + strP_Word + "'");
System.out.println(getUsersView().getWhereClause());
getUsersView().executeQuery();
return getUsersView().getRowCount();
In the JClient panel (JButton action):
Bc4jModule app = (Bc4jModule)panelBinding.getApplicationModule();
int n = app.authenticateUser(txtUser.getText(), txtPassword.getText());
System.out.println("Number of rows queried = " + n);
I would like to know if this is the best way of doing a custom query on the Entity Object or is there some other way that i'm missing?

The best way would be to:
[list=1]
[*]Design a view object in JDeveloper which has bind variables for the parameters you need to pass in at runtime. For example, your WHERE clause for your view object would look like:
LOGIN = :0 and P_WORD = :1[*]Add an instance of that view object definition to your application module
[*]Write your custom AppModule method like this:
public boolean authenticateUser(String strLogin, String strP_Word)
getUsersView().setWhereClauseParams(new Object[]{strLogin,strP_Word});
getUsersView().executeQuery();
return getUsersView().first() != null;
}[list]

Java code common to the applications modules

I need help to generalise some methods and include them in project.
I have some Java methods and I need it to be able to include/calll these methods from different application modules.
I need it accessible to all app modules.
Is there any way to do it?

what we do is create a root application module to be the parent of all our app modules. edit that root app module and add your other app modules as nested app modules under the "Application Modules" section. then in your child app module java code you can initialize your root application module by using the getRootApplicationModule() method:
YourServiceImpl yourServ = (YourServiceImpl)getRootApplicationModule();
then you have access to all your methods in the master app module. however, to make sure you're accessing your app module in the desired hierarchy, you have to base your jhs app def file on your root app module or use your app module under the desired hierarchy in any of your custom adf pages.
hope this helps

I accidentally added the app store apple id wrong, then I was able to put the right one but now that I need to update the application tells me to insert the id of the psw wrong, how do I change it?

I accidentally added the app store apple id wrong, then I was able to put the right one but now that I need to update the application tells me to insert the id of the psw wrong, how do I change it?

You must update the apps with the Apple ID that they are purchased with.
The only way to get round this is to re-purchase the app with the new Apple ID.

ADF panel executes all queries in the application module.

Hi all,
I have created an ADF Panel, which allows the user to run a few simple queries against an Oracle database done using ADF view objects and ADF view links and ADF application module.
As I add more functionality meaning more available queries meaning more ADF views and ADF view links, running the Application Modules becomes slower.
Let’s say the application module AM1 is made of 30 different view links. And application module AM2 is made of another 30 view links.
Now let’s say that ADF Panel1 references 8 view links from AM1, but it appears that all 30 view links that make up Application Module AM1 are executed before returning the result sets of the 8 view links referenced in ADF Panel1. Let me also underline the fact that each view link in Application Module AM1 can be executed independently, so the question is how I can make Jdev not to run all 30 queries in view links in the Application Module AM1 when ADF Panel1 is executed, but just the 8 that are referenced in the ADF panel1.
I hope I made my question understood.
Your inputs are greatly appreciated.
Thanks.
Bobby A.

Hi,
if this is what you see then you should file a bug because certainly its not the way it is designed to work. Note that in JDeveloper 11g - you don't specify the release you are on - the iterators by default are set to refresh deferred. Only iterators that belong to a PageDef file are executed when the page loads (you can suppress this by setting a refresh condition). Other queries are not executed

Problems with the Application Module Pool

Hello,
We have an Oracle ADF Application working in a production enviroment. The application module pool seems to work properly during the first days, but after a few days, the application module pool seems not to work properly. We start to get some errors like JBO-30003: the application pool failed to checkout an application module.
We have included in the application a DumpPoolStatistics servlet, and what we have observed is:
1. When the application is restarted in the server, the "total number of application modules in the pool" is equal to "maximum number of application modules in the pool".
2. Several days after, the "total number of application modules in the pool" starts to decrease.
We don't know why the "total number of application modules in the pool" starts to decrease, but we think this is the reason of the errors. In fact, "total number of application modules in the pool" is lower than the "jbo.ampool.minavailablesize" parameter value.
The management of the application module pool is not a task of the developer, so we don't undestand where is the problem.
We have configured the application module with the next parameters:
<jbo.ampool.initpoolsize>10</jbo.ampool.initpoolsize>
<jbo.ampool.maxpoolsize>100</jbo.ampool.maxpoolsize>
<jbo.ampool.minavailablesize>10</jbo.ampool.minavailablesize>
<jbo.recyclethreshold>15</jbo.recyclethreshold>
<jbo.ampool.maxinactiveage>600000</jbo.ampool.minavailablesize>
<jbo.ampool.monitorsleepinterval>600000</jbo.ampool.monitorsleepinterval>
<jbo.initpoolsize>15</jbo.initpoolsize>
<jbo.maxpoolsize>30</jbo.maxpoolsize>
<jbo.poolminavailablesize>15</jbo.poolminavailablesize>
<jbo.poolmaxavailablesize>25</jbo.poolmaxavailablesize>
<jbo.poolmonitorsleepinterval>30000</jbo.poolmonitorsleepinterval>
<jbo.poolmaxinactiveage>30000</jbo.poolmaxinactiveage>
<jbo.dofailover>true</jbo.dofailover>
<jbo.ampool.resetnontransactionalstate>true</jbo.ampool.resetnontransactionalstate>
<jbo.ampool.doampooling>true</jbo.ampool.doampooling>
We are working with JDeveloper 10.1.3.4.
Thanks in advance!

Sorry, you are right, the number of application modules created whe the application starts is given by the jbo.ampool.initpoolsize. But what it is sure is that the "total number of application modules in the pool" starts to decrease. The number of days is not always the same. But we have to restart the application occasionally.
I think the time parameters are ok, I would like for example 10 minutes for pool resoruce cleanup, and 10 minutes for considering an inactive AM instance in the pool as a candidate for removal during the next resource cleanup.
<jbo.ampool.monitorsleepinterval>600000</jbo.ampool.monitorsleepinterval> --> 10 minutes
<jbo.ampool.maxinactiveage>600000</jbo.ampool.minavailablesize> --> 10 minutes
Is this right?

If your profile is correct you're already on the final version of Snow Leopard (10.6.8). Sure it wasn't Lion it was asking for?
If that's the only version available on the app store, you'll need to source a copy of the iWork '09 DVD - not cheap now - only available via Amazon or eBay etc.
