How to refresh CR 2008 datasource

Hello,
We have upgraded CR 10 that came with the Visual Studio 2005 to CR 2008. However, just upgrading of the Visual Studio project was not enough, to make old CR 10 reports to work I have to open each report in the CR 2008 application (not the Visual Studio), refresh their data source and save, after this they work.
I'm using datasets as a datasource, so I don't have problem with it. But some reports I inherited from the previous developer. He was using a C# class as a datasource for reports. It's just a C# class file - InvReport.cs. This file contains field definitions for several reports.
I cannot figure out how to refresh this datasource. Class file is not in the list of the datasources for Crystal Reports, so whatever I'm trying to do in the Database Expert (or by setting datasource location) fails.
Could you please advise me on how to deal with this situation? Or perhaps there is another way to to upgrade the old reports to 2008 version? According to Visual Studio - they all had been upgraded automatically, but in reality they don't work until I open each one in the report application and refresh datasource.
Thank you,
Peter Afonin

Peter,
Rather than updating the reports from VS2005 I would suggest you to use CR2008 designer. During updating of the application the reports might not have got updated properly as it depends on the complexity of the reports like stored procedures, formulas etc. So I would suggest you open the .rpt file in designer, Go to Field Explorer -> set data source location and then create a new connection in Replace with window and update the fields in Current datasource window.
Preview to ensure the report displays proper data and then use this report in the application.
Hope that helps!

No datasources in SPM after all refresh datasources option

Hi,
I tried Refresh all data sources option in SPM, checking the log it showed that the Metadata loaded message. But post that, I could not see any data sources in User preferences or datasource Administration. But I could the list in Application properties.
This is a crtical issue as till this is resolved no reports are displayed.
Regards,
Sampat Desai

Hi Sampat,
We have seen this error in the case when some user is saving reports at the same time when refresh datasource is being done. Please try following steps which should most likely resolve this issue:
    1) Delete all nodes under the folder "/application/metadata" using the methods OPM_PS_GET_NODE_METADATA and OPM_PS_REMOVE_NODE(Please note that /application/metadata itself should not be deleted)
    2) Go to table "OPM_PS_ITEM_DET" and search for all objects with "NODE_TYPE" as "AUI_METADATA_CACHE". This will return all the nodes which are dangling as there should be no such value.
    3) Retrieve the GUIDs from step 2 and remove the existing nodes using the FM OPM_PS_REMOVE_NODE
Thanks,

How to refresh/initialize sy-tabix in a loop?????

Dear all,
Please do let me know how to refresh/initialize 'sy-tabix' for every new document in a loop statement.
Thanx in advance.
Alok.

Never try to refresh or initialize system variable. It shall always lead to errors in the programs. For this I have an alternative way below.
Please declare a variable for e.g
data: <b>l_count</b> type sy-tabix.
Inside loop you can write the code like this:
say for eg. you need to refresh l_count for every new material.
Loop at itab.
on change of itab-material.
clear : l_count.
endon.
l_count = l_count + 1.
endloop.
Hope this clarifies your issue.

You never delete a Time Machine backup by dragging it to the Trash. You are supposed to use the TM application to manage the backups. What you will need to do now is to simply erase the drive using Disk Utility.

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();

Thank you,

Hi Hari,
Yes i have a apex page redirects from the ebs menu like you said. But for the refresh issue instead of modifying in the jsp i thought of bringing the automatic refresh for that apex page once it is loaded within apex.
However these type of issues are sometimes get fixed by clearing browser cache or just by restarting your browser. Have you tried it?Yes i have tried, by clearing the browser cache and also by restarting the browser then too it still persist.
Any DA action will be helpful for refreshing that page for 1sec once it is loaded. Since i dont want it to be loaded multiple times often once it is loaded.
The refresh has to be only once if the page is loaded.
or is it possible to Refresh the page based on the application page item through DA
Thanks
Brgds,
MiniTechnically Yes, you can create a D.A. that will fire only once based on some apex page item or application item value. However this is NOT the correct solution.
<li> When you see apex page (after clicking menu in EBS), do you see apex url in browser address bar? Can you post the URL here?
<li> If you directly log-in to APEX (not via EBS), do you still face this issue?

How-To "Refresh a table of data after inserting or deleting"

I'd like to say a word on the how-to article "How to refresh a table of data after inserting or deleting a row using ADF".
(http://www.oracle.com/technology/products/jdev/howtos/1013/updtable/index.html?_template=/ocom/technology/content/print)
I spent a lot of time on it because I needed help in implementing simple CRUD functionality on a table, using JSF-ADF-TopLink technologies.
While the the article does provide correct steps, it is in one important place not specific enough, so the reader may easily get stuck. In section "Refresh the data table", point 1: when you double click on the removeEntity() button, in Structure window, then you do not get the required dialog. You get CommandButton Properties dialog.
You must click on the removeEntity() button in Editor's Design view. But even there you may get the CommandButton Properties dialog, not managed beans dialog.
You may resolve that by going to JSF configuration file, faces-config.xml, and switch to Overview view. This will show you the managed beans that you have.
Then, you may already have a backing bean for the page. You can use that and avoid creating a new managed bean.
I could understand what the operations mean only after very careful reading of "Creating More Complex Pages", section "Overriding Declarative Methods" in JDeveloper Help (or in ADF Developer's Guide PDF document).
In general: I believe that "ADF bindings" need more conceptual explanation, maybe in form of an article. Grammatical form "bindings" may create a false understanding that "bindings" are just references. But they are not -- ADF bindings are active objects that handle traffic between UI components and Data Controls. It seems that "bindings" even communicate among themselves. Maybe it would be more understandable to differentiate strictly between "binding objects" (or "binders"?), binding object definitions and binding object references.
It would be very helpful to have a diagram showing grahically what specific binder objects are created in a small apllication (2-3 pages using 1-2 tables), with whom they communicate and what type of data is passed on.

Hi
Thanks for your infos.
Yes exactly I use almost the same code you have post here.
Could You answer to my next questions?
First - >what do you mean by saying that "it's not good idea using refreshing in IE?" Of course I use refreshing in backing_bean for my button "remove" that removes row, commit changes to database and refresh table, almost the same as You said in your post:
Code in backing_bean is and comments on difference to Your code is below:
public commandButton2_action1(){
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("removeEntity");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
//above remove entity, but I dont now if it do commit to database? So i do it below
OperationBinding commit1 = bindings.getOperationBinding("Commit");
commit1.execute();
//and at the end I refresh my table, "findAllRezerwacja1 - it is an id of the methodAction, not the iterator -> is it ok? or should I change to Iterator id?
OperationBinding requery = bindings.getOperationBinding("findAllRezerwacja1");
requery.execute();
return null;
Page Definition code for this:
<methodAction id="findAllRezerwacja1"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="findAllRezerwacja"
RequiresUpdateModel="true" Action="999"
ReturnName="SessionEJBLocal.methodResults.SessionEJBLocal_dataProvider_findAllRezerwacja_result"/>
<table id="findAllRezerwacja2" IterBinding="findAllRezerwacja1Iter">
<AttrNames>
<Item Value="dataDo"/>
<Item Value="dataOd"/>
<Item Value="idRezerwacja"/>
<Item Value="liczbaUczestnikow"/>
<Item Value="prowadzacy"/>
<Item Value="uwagi"/>
</AttrNames>
</table>
<methodAction id="removeEntity" InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="removeEntity"
RequiresUpdateModel="true" Action="999">
<NamedData NDName="entity"
NDValue="${bindings.findAllRezerwacja2.currentRow.dataProvider}"
NDType="java.lang.Object"/>
</methodAction>
<action id="Commit" IterBinding="findAllRezerwacja1Iter"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" RequiresUpdateModel="true"
Action="2"/>
</bindings>
//and rest of code for Iterator etc
My second question is, why when you use refresh button in IE (I know is not recommended as You said, but sometimes user do it, so I want prevent situations that I will describe here) so when I press refresh button in IE exactly after removing one row by clicking my button, refreshing by pressing IE button is doing the same --> is deleting next row. How to stop deleting row, when for example user would press IE refresh button after pressing remove button for table. If I change selection in table after deleting row, and press refresh button in IE, instead of deleting row, I got error message: JBO-29000: JBO-35007: and
JBO-35007. So where Im doing wrong. Maybe I should do sth with postback ? Could You help me? Thanks in advance
Last one question: what is the difference between using delete and removeEntity from operations node? Im now reading carefully ADF Dev Guide, so I hope I can find infos there? But if You know, please answer to this question.
Thanks

How to Refresh a Single Graphic based on Time of Day

On this Muse Developed Website, HOME | The Great American Car Wash, The traffic light is programmed to change to Red when the business is closed and to green when it opens. The code that I wrote incorporates this meta tag:
<meta http-equiv="refresh" content="5"/>
This refreshes the entire page every 5 seconds. The page blinking as it refreshes is undesirable. My best temporary fix is to change the refresh rate to 2 minutes. I have it tentatively set to 5 seconds for troubleshooting. It will be set to 30 seconds when it is time to publish the site.
I used the "INSERT HTML" command in Muse to add the code. It works as intended, except for the annoying page blink to refresh the traffic light. The business owner could easily tolerate a traffic light blinking on refresh.
Is there a way to just refresh only the graphic? Or is there a better way to automatically "update" the status of the light?
Thanks.
