Failed to open model viewer error, for Decision Tree Model

Oracle 11.0.2
SQL Developer 3.0.04
I am trying to follow ODM tutorial here :
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/bidw/datamining/ODM11gR2.htm
After completing initial analysis, I want to investigate the Decision Tree model more closely. As I choose View Models > CLAS_DT_1_1, I get an error message:

I get this error for Decision Tree Model only. For other models, there is no problem. How can I fix it?
Thank you.

After setting system language to English, be sure to restart SQL Dev to retry the test.
Make sure you have the latest patches installed.
Go to menu: Help-> About. In the About dialog, select the Extensions tab and check if you have Data Miner version 11.2.0.2.04.40. If not, go to menu Help->Check for Updates, and install the SQL Developer and Data Miner patches.
SQL Dev 3.0 is not certified with Java 7.
Thanks,
Marat

Failed to open the connection error using Business View OLE DB

I have a Crystal Report built on a Business View with the db being accessed by an OLE driver. Everything works fine using Crystal Designer, but when I try to access it through BOE I get the "Failed to open the connection" error. I have the ole drivers installed on the server.
We are on BOE 12.1.0.
The db is IBM as400.
Suggestions??

Ok so I spent the day trying to find the differences between the working and the non-working application. I began by adding code one piece at a time to the working application. The goal was to try and get it to break on the deployment server. I found the lines of code that is causing the break on the deployment server. Here it is:
    private void setReportParameters()
        try
            crystalReportDocument.SetParameterValue(0, reportUserName.Value);
            crystalReportDocument.SetParameterValue(1, reportArea.Value);
            crystalReportDocument.SetParameterValue(2, reportCDR.SelectedValue);
            crystalReportDocument.SetParameterValue(3, reportStatus.Value);
        catch (Exception ex)
            throw ex;
This sub-routine is called from my button click code and is used to set the parameters for the report. Once I added this to the working application it broke also. My goal here is to send the parameters to the report from a form the user is filling out. Please keep in mind this code works in Visual Studio 2005 and my local IIS server running on my development machine. It breaks on the target deployment server
The code broke on reports with sub-reports as well as report with no sub-reports. As soon as it was added and deployed the application through the "Failed to open the connection" error.
Thoughts?

Item Open Interface giving error for Org Assignment

We ran the MTL_SYSTEMS_ITEMS_INTERFACE & loaded all the items at master level.
We are having issues in setting at Org level. Cant figure out what the issue as only few records gets assigned & then garbage sets in for remaining records. An SR has been raised & the tech support representative was saying that UOM's are different at master & org levels. Never heard of this issue earlier. I have worked with UOM's different at Master/Org levels.
The UOM's are different at Master & Org Level and in some cases the UOM are different for different Orgs. Attribute Control for Primary/Sec UOM is at Org level. The UOM's belong to the same UOM Class. There are standard conversions defined for all these UOMs.
Any pointers for quick resolution ?

Failed to open the connection: Error Code 17

Here's an odd one.
Environment:
VB.NET Winform
Visual Studio 2008
.NET framework 2.0
Crystal Reports 2008
ODBC connection
I have three reports, living in the same directory. They are essentially identical, except for the grouping. All three run successfully within Crystal reports.
From a report viewer Winform in VS, two of the three run. As I am dealing with a small data set, the reports render quickly. On the third report, There is a long pause when the report viewer form opens, then I finally get an error:
"Failed to open the connection.
Details: [Database Vendor Code: 17]
Failed to open the connection.
CallReportByExtension 58F5C135-7BA3-4215-898A-DADA6C7DAD9C.rpt
Details:[Database Vendor Code: 17]
I was initially getting similar errors on all three reports, before changing the datasource location to my ODBC connection. I have double-checked the location, verified the database, etc.
What am I doing wrong? I can provide the VB code if requested, but since the other two reports work properly, I doubt it's code. I do know that I am passing the report name and path correctly to the report viewer form.
As I am about to kick my monitor through the window and become a street denizen, I would greatly appreciate any help that would be offered.
Thanks,
Mike Beckner

"Extraction Failed: Cannot Open Output File" error message when installing new drivers

Hello, I'm trying to install new drivers for my HP Photosmart C4385 Printer. I downloaded the full feature drivers for Windows XP 32-bit, and when I start to install (extract), I get the error message:
Extraction Failed
Cannot Open Output File
And the process closes. It happens at about 85% extraction every time.
Any idea why? I called HP but since it is out of warranty they wanted money, which I think as absolutely ridiculous - won't even give me basic support?? Poor, poor customer service.
This question was solved.
View Solution.

Hi,
If you haven't still got the Full Feature software installer, download it from the link below and save it to your Desktop. If you already have it, place it on your Desktop.
ftp://ftp.hp.com/pub/softlib/software10/COL20274/mp-53147-4/100_228_PS_AIO_02_Full_USW_enu_NB.exe
Make sure the Printer is disconnected from your PC.
Download and install 7-ZIP. Once installed, right click on the software installer for your printer, select 7-Zip and choose extract files, then click Ok.
Open the newly extracted folder and double click the setup application to start the installation ( the setup application will probably have the same icon as the original software installer you downloaded ). Connect the printer to your PC when the software asks.
Hope this helps.
Best wishes,
DP-K

Failed to open a rowset error

Post Author: lala1
CA Forum: General
Hi,
I am getting the following error in Crystal reports:
Failed to open a rowset
Details: HY000: [DataDirect][ODBC Oracle Driver][Oracle]ORA-06550: line 1, column 8:
PLS-00306: wrong number or types of arguments in call to 'RUN-REPORT'
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
This is happens anytime I want to edit something in a report: I have tried to reinstalled crystal and the oracle client, but it did not work. Also checked the ODBC settings. Someelse tried to run the reports on their crystal and they did not come across any problem. We both run the same version of Crystal reports.
Can you please help as it is preventing me from doing anything in Crystal?
thanks

Deepa,
I've run into the same deadlock error. It usually happens to me when I'm running reports that are particularly intensive in terms of server memory and / or processing, such as correlated sub-queries or looping statements involving big tables. It will also happen when there is heavy usage from the from end application, by front line users.
I'm no DBA, but I get the impression that SQL Server is smart enough prioritize requests. Basically, it deadlocked the report request in order to keep other processes up and running.
My solution... Wait for "off peak" times to run these types of reports. Also I publish my reports to CR Server and schedule them to run at night.
Hope that helps,
Jason
PS If you do find a way to avoid this error without compromising front end application performance please post it. I hate, it makes me nuts too.

Palm Desktop software - Fails to open with msg "Error: Failed to open Address Book database"

In July 2009 I dropped my trusty Visor on a tile floor and it stopped working. So, in the meantime I have been using only the Palm Desktop software.
Just yesterday, when I attempted to launch the Palm Desktop software, it failed with the message “Error: Failed to open Address Book database”. I think this error was caused by a very ungraceful shut-down of my Win XP system yesterday.
I really do need to use the Palm Desktop software for my address list, calendar, and memo. The problem is that the error with the Address Book database seems to be preventing the Palm Desktop software from initializing.
I am using Palm Desktop 4.0.1 on Windows XP SP3. I do NOT have an export file of the Palm address book or other databases. However, I do have five levels of backup history on my external Maxgor backup drive.
Specifically, on my current c drive I have files in the directory:
C:\Program Files\Handspring\WR\address
            address.bak                  5/16/2009   (from last sync before I broke Visor)
            address.dat                   5/24/2011
            Personal.ABA   11/6/2008
            Unfiled.ABA    3/28/2008
On my most recent backup of my system, there are the following files:
                        address.bak                 5/16/2009   (from last sync before I broke Visor)
                        address.dat                  5/12/2011
                        Personal.ABA   11/6/2008
                        Unfiled.ABA      3/28/2008
I have not listed the four older backup versions.
I haven’t tried any corrective measures yet (I don’t want to make matters worse) and am hoping that someone can guide me along the right path.
Is it possible for me to just rename the “current” address.dat file to something like address.SAV and then copy the Address.dat file file with date of 5/12/2011 into the current directory. Will the software then just use the older version of the data, or must I do something else.
I am grateful for any assistance. Thank you very much.

Thanks for the speedy response. However, I read the article for which you provided the link, and I hve also read many other articles that I found via search, but I don't think these will help me. All of these articles seem to assume that (1) you have a handheld to which you can sync and thereby rebuild the database on the PC, or (2) you have a backup that you created via the Palm Desktop export function. Unfortunately, I have neither and so I don't think any of these solutions will work for me.
I did read with great interest an article that stated that recent versions of Palm Desktop have a built-in function that will repair a corrupted Datebook database. Will this also fix a corrupted Address Book database which is my problem?
So, I downloaded and attempted to install the latest version of Palm Desktop. I was careful to read the instructions that stated NOT to uninstall my current version of Palm Desktop, but to just install the latest version on top of my current Palm Desktop. However, when I attempted to do the installation, the installer software said it could not install on top of my current software and that I should first uninstall my current software.
I have some questions now:
(1) If I uninstall my current version of Palm Desktop, will this destroy my Address Book, Datebook, and Memo databases ( I don't care about the ToDo database)? If so, what can I do to preserve those databases?
(2) Is there really a function built in the recent versions of Palm Desktop that will fix a corrupted database? Is this an "automatic" function that will detect and fix a broken database or is this something I will have to invoke?
Thanks for your help.

Palm Desktop software - Fails to open with msg "Error: Failed to open To Do List database"

In July 2009 I dropped my trusty Visor on a tile floor and it stopped working. So, in the meantime I have been using only the Palm Desktop software.
Just a couple days ago, when I attempted to launch the Palm Desktop software, it failed with the message “Error: Failed to open To Do List database”. I think this error may have been caused by a very ungraceful shut-down of my Win XP system the day before.
I really don’t care about the To Do List data since I really don’t use it --- in fact, I haven’t used it in many months. However, I really do need to use the Palm Desktop software for my contacts, calendar, and memo. The problem is that the error with the To Do List database seems to be preventing the Palm Desktop software from initializing.
Just guessing, I saved the todo.dat and todo.bak files by renaming them, and then renamed the todo.bak file to todo.dat. Then I attempted to launch the Palm Desktop application, but it failed with the same error “Error: Failed to open To Do List database”.
I also tried renaming all of the todo files so that none had a name of todo.dat or todo.bak. The result is that the Palm Desktop software still will not start up.
I think I am using Palm Desktop 4.0.1, at least that is what the help text file seems to tell me.
I am grateful for any assistance. Thank you.

Your on the correct path by saving the data by renaming the files. But to resolve this error we need to remove the data all together. Since you no longer need this data if you just delete it then it should not matter. If Palm Desktop is giving this error but will not open I doubt that the data can be recovered in any event.

Unable to view error for website created on iWeb

We have hosted a website created on iWeb. When we access the site we often get the following error message. We contacted the hosting company, but they asked us to make the changes on the web pages as suggested in this error message in order to be able to view the actual error. Only then will they be able to help us out. Can someone help us incorporate these changes in our web pages.
Thanks

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

In my first posting (just below my name) I've quoted the entire content of the error message that pops up. But it only pops on certain occasions, it doesn't happen every time. The other curious fact is that this message does not give you the actual error. It only tells you to make certain changes in your script so that you can view the error remotely. Therefore, until we are able to make these changes in the script or html code for the web page, we won't be able to know the actual error. When I tried to view the code or script of my web page, I didn't find a place where I could make these changes. Can you help me in this respect?
BTW I was trying to study the pattern of these error messages and I think I've found a correlation. However, I'm not sure if that could be a valid reason. It seems like every time I update my website, people get these error messages until about 3-6 hours after each of these updates. Once a reasonable time has elapsed after the update, the site seems to be working fine. Could it be due to a conflict between the older & newer versions of the web page being simultaneously resident on the site for a while after the update. Or could it be due to the change in the index file? Pl comment.
Thanks

Log aborts, with Failed to open log file error

Flash Media server version 2.0.3 periodically fails to open

roll time as it occurs at c.01:50. Does anyone else have a similar
issue ?
I am running Falsh Media Server on windows 2003 server SE!
Any help would be much appreciated.

Are you trying to run this code from job or something? Check if account executing the package has access to the path. Also check if path value passed is correct. If its a remote system path pass it in UNC format (ie //machine/...)

Problem in datamining :Wanting package holding classes for Decision Trees

Hello,Friends.Please,I have downloaded the package odmapi.jar several times (several releases ) but there was a problem that I did not find the class DecisionTreesSettings(or classes concerning to Decision Trees ) in the path :oracle.dmt.odm.settings.algorithm...
Please help with giving me release of this package that holds this class....thanks

I only have to put null in the instance variable declaration for it
to pop up again in my application.This almost always points to you performing some initialization from a superclass constructor. I know you say this isn't happening. However, it's by far the most likely situation. You could also have threading issues, as you don't synchronize your singleton creation.
FYI, Java initializes class instances using the following (simplified) sequence
1) Allocate the memory and initialize it to default values (nulls for references, 0 for numbers, false for booleans). This happens before any constructors are called.
2) For each class in the hierarchy, starting with Object, invoke the instance initializers and appropriate constructor. If a superclass constructor changes a variable defined by a subclass (typically by calling one of the subclass's methods), that value will be overwritten by any instance initializer (or constructor-time assignment) of the subclass.
For testing, I suggest you put logging messages in the code that assigns the variable, and at the start of the subclass constructor. You should probably log the current thread ID, and it wouldn't hurt to dump a stack trace as well.
Edit: wow, lots of posts between the time I started writing this and the time I finished ... oh well, perhaps the OP will understand instance initialization better if he/she reads this.

Maximum open Cursors Excedded error - for every transaction

Hi All,
I am getting the maximum opn cursors exceeded error suddenly for every single db transaction i am trying to make in my application. this did not happen previously during my developemnt and testing phase.
I have a question here that i tried to google but failed to get satisfactory answer.:-
When we use a cursor in the stored procedure to fetch data, how to make oracle automatically close the cursors once the stored proc finishes executin. Or is there something i have to follow other with my current open cursors limit to ensure this problem does not happen?
Thanks,
Chaitanya

Hi Justin,
My oracle stored procs are called by java framework. In each place i was closing the connection object but there were a few places where i was not closing the resultset object which directly pointed to my oracle cursor.
I have closed the objects in such places and tried again but still i am getting the same error. Mit it be an instance where the oracle db is not allowing me to connect to it at all. Something like restarting it would help? Restarting the server where the oracle software is hosted.
Please excuse my blatant ignorance in this issue.
Thanks,
Chaitanya

CRVS2010 Beta - Report Viewer Errors for Crystal Reports in VS 2010

I have a project that was written in VS 2008 targeting the 3.5 framework which contains a ton of Crystal Reports. I recieved my new license for VS 2010 and did the install along with the Crystal Reports for Visual Studio 2010 Beta 2. I converted my project over successfully. I am able to open up the reports on their own. When I try to save them they want to be converted to the new format. This also works fine. My problem is the Crystal Reports Viewer. I am not able to add any reports to the viewer without receiving error messages. I have tried using the 10.5 and the latest version of the viewer, but receive errors everytime that I try to add a report to it. I always recevie the following error:
"Error invoking 'Choose a Crystal Report...'. Details: Invalid Report Source"
I have also tried just creating a brand new report from the Crystal Report Viewer Tasks window. When I do that I get this error:
"Unable to find the report in the manifest resources. Please buld the project, and try again." "Error invoking 'Create a New Crystal Report...'. Details: Unable to find the report in the mnifest resources. Please build the project, and try again."
I have tried changed the framework target to 4.0, but this has not helped. I have tried using the 14.0 versions of the references and the 10.5 versions. I have searched all over the internet for a resolution, but can't seem to find one. Any help would be greatly appreciated.

I am having the same problem. You say make sure all of my assemblies are version 14. Three questions:
1. Now that I have removed all of the old Crystal assemblies from my project, what are the assemblies that I need to add back?
2. My VS 2010 "add references" popup shows me many crystal assembles (Crystal XI is also installed) which ones to I need to install now?
3. If I don't know what they are, or where to find them, how do I determine their version?
You solution reminds me of the old saying "If I had ham, I could make ham and eggs. If I had eggs!"
More information please,
J Rich

Well, I compared my classpath between my windows batch file and the
makefile (that comes with the samples installation) on Solaris and realized
that I am using different sets of jars.
So, I removed the extra jars from the makefile to narrow down the
problem. If I remove the /opt/SUNWam/lib/servlet.jar from the makefile,
I can reproduce this problem on the Solaris box as well.
When I include this servlet.jar on my windows machine the program works!
Only jars I have in my classpath are amclientsdk.jar and servlet.jar which
I have copied from my installation (/opt/SUNWam/lib) on the Solaris box.
Just the same way, by copying the am_services.jar, saaj-api.jar, and jaxm-api.jar,
from the Solarix box to the windows machine,
I am also able to pull the assertions from the Access Manager.
I installed Sun Java Enterprise System 2005Q1 on a Solaris 10 machine.
During the installation, I configured to install the Access Manager
in Sun Application Server.
Why do I need to have different set of jars on the windows machine
for the Access Manager client SDK ?
Could you please point me to a download link where I could download
the correct Windows Access Manager Client SDK for
Sun Java System Access Manager 6.0 (Sun JES 2005Q1)?
Thanks.
