How to use one Assign action to create multiple context variables

Hello, everyone.
I read some tips from Oracle documentation that said:
Avoid creating many OSB context variables that are used just once within another XQuery
Context variables created using an Assign action are converted to XmlBeans and then reverted to the native XQuery format for the next XQuery. Multiple "Assign" actions can be collapsed into a single Assign action using a FLWOR expression. Intermediate values can be created using "let" statements. Avoiding redundant context variable creation eliminates overheads associated with internal data format conversions. This benefit has to be balanced against visibility of the code and reuse of the variables.

But I don't know how to do that. Can you show me ?
Thank in advance

if you return sequences, you can declare the return type of your xquery as xs:double*
(notice the asterix at the end)
but I have the impression that in the assign action only the first element will be assigned to the context variable
(correct me if I am wrong)
So in fact you might indeed have to transform the sequence into a element()*, or concatenate it into a CVS string - for instance using string-join

How to use one pop up window for multiple buttons and input fields?

Hi Experts,
I have created a pop up window that will be opened from multiple buttons in the same view. There are input fields that the data will be populated from a pop up window. How can I set up which button that a pop up window is opened from? I also would like to populate the data from a pop up window to the input field next to a clicked button. There are 6 buttons and 6 input fields that share the same pop up window. I would very appreciate your responses.
Thank you,
Don

Hi,
Try creating 2 context attributes, one in your component controller and the other in the pop-up view. Bind the attribute of pop-up view to the component controller attribute.
In the main view, on click of every button set a unique code in the controller's context which helps you in identifying the button clicked. Since u have created a binding to the pop-up view attribute the value flows from the controller.
In the init method of your pop-up view, check the value of the attribute and based on that display which ever UI elements are required.
Eg:
On Button 1 click set value "B1", Button 2 value "B2" etc. In the init() of pop-up view u can check the values and perform the required operation:
if(("B1").wdContext().currentContextElement().getButtonIdentifier()){
else...{
Hope this helps you.

How to use one pageflow to cater for multiple display?

Hi, I trying to use one pageflow to display different kind of contents because the logic behind the retrieval is similar except that different parameter(string) us passed in for different content retrieval.
How do i achieve the above? thanks in advance :D
Cheers

What do you mean by "display different kind of contents"? do you mean you want to display PDF/HTML/Image based on certain parameters or You are using different media like PC/PDA etc.
In both cases you can redirect to different success page based on your query parameters.
if(param.equals(image))
forward image.jsp
if(param.equals(pdf))
forward pdf.jsp
else
forward html.jsp
Hope it helps

How to use one I-tunes library with multiple windows users (family) on 1 pc

On our family pc we log in with different accounts. We want to use I-Tunes but all have the same library. I tried to create a library not in the users directory, but in the All Users folder that is accessible for everyone. However, when I import the music in the library for one user and set the same location for another user, I-tunes does not recognize the library. So everyone has to create it's own library.
What are the best practices to overcome this?

Keep in mind that what you have done now is you have multiple iTunes libraries accessing the same media folder. Meaning, that each account can have their own ratings, playlists, etc. but more importantly, each account does NOT know what the other account does, so if your daughter adds a CD to her account, it will go into the shared folder, but it will NOT automatically go into your wife's iTunes library. She would have to add it manually. Likewise, if one account deletes music from their library and tells iTunes to remove it to the trash, the other accounts will not know and iTunes will still try to access the file from the shared location even though the file is now trashed.
Each account has their own database files (.itl files in the iTunes folder) which stores this stuff.
If you want to have everyone use the exact same library which means the same ratings, playlists, etc. then you need to move the database files into that same location and set each iTunes account to read the same data.

How to use one dynamic connection managers for multiple parallel data flow tasks

hi there:
I have 6 databases residing on the same server. What I want to do is call a store procedure with identical name on each database dbo schema and transport results to a centralized place. The key is to have those SPs run in parallel instead
of in sequence as each SP may take around 10 mins to finish.
The simplest way is to create 6 OLE DB connection managers and create 6 DFT tasks. However, I do not want to maintain 6 OLE DB connection managers as there is a chance to have more connection managers.
What I did so far is to create a OLD DB connection manager and use expression to set up connectionString properties so that it will get populated by variables at run time. It is fine when running all SPs in a Foreach Loop Container. However, it takes
around 60 mins to finish.
When I try to run it in parallel ( basically created 6 DFTs but use only one Dynamic Connection Manager), the connection string gets confused therefore all DFT tasks failed.
Does anyone here have some experience on this topic?
Thanks
hui

Yes, basically, on the connectionString property of ONE OLEDB, you are using an expression to supply value and this expression is pointing to a variable.
In this case , you can update this variable from a table which contains many connection strings. It's good if you want to execute Store procedures in a sequential order. When in parallel mode, this will cause issues as connectionString gets overwritten.
I am thinking about using script task to exec sp.
The whole idea is that I do not want to maintain a large number of Connection Managers.
Hope it helps
--Currently using Reporting Service 2000; Visual Studio .NET 2003; Visual Source Safe SSIS 2008 SSAS 2008, SVN --
So you are not able to run parallel executions using same conn mgmr, even with dynamic connectionstring, is that correct? Yes, script task will be a way to go if you wish to execute it in parallel, you may connect to SS and query the proper conn string with
SELECT/WHERE clause in each script > pass it to a script variable > use that script variable and execute the proc. This will require only two things to change in each script, the WHERE condition to get the conn string and the proc name (you may even
get the proc names the same way you get conn string) and everything else will be same. Let us know how that goes.
Hope no two or more procs doing insert/update/delete on the same tables.

How to use one commandButton to execute two task in JSF

I have a form in JSF page which contains different faces components. These faces bind to ADF BC to insert one row in the database when the user press commandButton. Also I need to bind the value of one inputText in that form to managed bean to execute another task in the application when the user press the same commandButton.
The code of the inputText:
<h:inputText value="#{bindings.ProjectNumber.inputValue}"
id="pn"
size="10"
required="#{bindings.ProjectNumber.mandatory}">
The code of commandButton:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}"/>
The managed bean is “findInspector”. I tried to insert inputHidden inside commandButton tag and assign the value of the inputText to the inputHidden as follows:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}">
<h:inputHidden value="#{bindings.ProjectNumber.inputValue}" binding="#{findInspector.project}"/>
</h:commandButton>
But it was not work
Please how can I write the code to use the value of the inputText more than one time in the JSF(one to insert one row by using ADF BC and another to use the same value to bind to a managed bean) and how to use one commandButton to execute two task in JSF.
Thank you
Waheed

Yes I did
<managed-bean>
<description>The bean for get project No</description>
<managed-bean-name>projectBean</managed-bean-name>
<managed-bean-class>
mcscm.model.ProjectBean
</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>bindings</property-name>
<value>#{bindings}</value>
</managed-property>
</managed-bean>
Also I changed the method in the managed bean as follows:
public String commandButton_action() {
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding vb = fctx.getApplication().createValueBinding("#{bindings}");
DCBindingContainer dcb = (DCBindingContainer) vb.getValue(fctx);
OperationBinding operation = (OperationBinding) dcb.get("projectNumber");
operation.execute();
return null;
where projectNumber is my method in the java class of the application module "TaskInformationImpl". I made this method to be accessed from outside of ADF BC.
I just create a sample code for projectNumber method for testing only as:
public void projectNumber (String data){
System.out.print(data);
In the page Pagedef file I added this :
<methodAction id="projectNumber"
InstanceName="TaskInformationDataControl.dataProvider"
DataControl="TaskInformationDataControl"
MethodName="projectNumber" RequiresUpdateModel="true"
Action="999" IsViewObjectMethod="false">
<NamedData NDName="data" NDValue = "#{bindings.ProjectNumber.inputValue}" NDType="java.lang.String"/>
After I did all of this I get a new error like:
javax.faces.FacesException: #{projectBean.commandButton_action}: javax.faces.el.EvaluationException: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlAttrsBinding cannot be cast to oracle.adf.model.OperationBinding
Is it very difficult to do this in JDeveloper?. yes ADF BC provide me a lot of facilities, but when I want to do a specific task I face a lot of troubles

Just dopublic void execute() {
anotherAction(inputValue);
I guess those articles might be interesting about passing params and the usage of inputHidden and also about using datatables:

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

How to use one ODSI project artifact as jar for other ODSI project?

Hi,
I am working on multiple ODSI proejcts in Same Server. My problem is how to call one projects resources in other ODSI project. I need this as Some of Data Services read the data from more then one database. The projects are in seprate Dataspace projects but they are deployed in same server. When I try to export artifacts from one projects and include them as Jar in other projects I am not able to see any Data service methods so unable to call any method of one project in other project. Please advise how to recsolve this problem.
Thankyou in advance.
Rahul

If you already have a case open, it's polite if you mention that - so I don't have to answer the same questions to support and also to this forum. Likewise, when you get an answer to your question on this forum, you can tell support. So they don't keep looking for something you already have the answer to. Cuts down on the duplication of effort.
You have one project. You add more files to it (regardless of how you add them - by creating files with the editor, by using a wizard or by importing files from another project), you still have only one project.
If you had some other project that you exported the files from - that project is still there - but the original project does not know or care about it.

How to use one DC's view/component/appln in another DC

 From this point onwards I am not getting any clues. How do I call A's component in DC B. Please guide. Any examples will be great.
Thanks and Regards,
Ganga.

Hi Gangadharaya,
Just tell me do u want to display a view, use some context or use some methods defined in other controller.
So that i can help you in the same direction.
Component Usage
Suppose you have following scenario:
1) DC2 has component Comp2. In this dc you read the context a value and stores it in context named "Ctx_value".
2) DC1 has component Comp1. Here you want to read the Ctx_value from comp2.
In Comp2 create a method getValue()
public java.lang.String getProcessId( )
 return wdContext.getCurrentElement().getAttributeValue("Ctx_value");
In the interface controller of Comp2 click on properties tab and add reference to the cont2 controller. Now create a method here in interface controller to get the value of Ctx_value
public java.lang.String getValue( )
 return wdThis.wdGetComp2Controller().getValue();
Expose the Comp2 as public part now.
In DC1 add DC1 as used DC.
Build both dc's
In Comp1 create Component usage by name Comp2Usage to Comp2.
Now you can access the method getValue() from interface controller of Comp2.
wdThis.wdGetComp2UsageInterface().getValue();
This is how you can access a value of Context. Same can be done by direct binding.
View Access
If you want to access a view v2 in comp2 then goto windows in comp1 and embedd an existing view and in that select the interface view of comp2. The default view in comp2 can now be displayed in comp1.
