Intermittent error when using the Disco Viewer client

Hi, I have a user receiving the following intermittent error when using the Discoverer Viewer client:
“The application encountered an invalid state.
- Discoverer Beans XML Exception. Method: findNode Class: XMLUtils Error: Cannot find parent node. Parent element does not exist in XML document, looking for database_account/eul
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.”
Any idea what this might be? Any help or direction would be very much appreciated! Thank you!

Hello
Is this related to a single machine or common to a single report or is it purely random?
I did a search on your behalf and came up with nothing related to this error. You may therefore need to raise the problem with Oracle Support.
Just out of curiosity which version of Discoverer are you using?

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

Multivalue error when using the previous() function

I am getting a multivalue error when using the previous() function on a dimension object in the report. I thought that the previous function was supposed to look at the current report and then look at the previous record's contents. How could this possibly give me a multivalue error when the value is clearly output in the previous row? Anyone have any ideas?
By the way, this is a valuable function for the types of reports that I design. The next() function would be even more valuable.
Thanks for your help.

Hi Michael,
Could you please test the following solutions it might help you to resolve the issue.
Solution1:
Use slice and dice to reset all the tables that have #multivalue in it. The only problem with this workaround is they have to do the formatting manually.
Solution2:
Also, test the issue by changing the object to dimension if it is a measure or to measure if it is a dimension.

TS1702 unknown error when using the app store

unknown error when using the app store

Im sorry I will try to be more clear.. and I appreciate all of ur input. Wi-fi works fine.. everything opens and functions fine on the I pad. The problem is I will click on app store or the I tunes store...it opens fine and I am able to look at and download apps etc... but after being in the appstore or I tunes store for a couple of minutes I get kicked out to the I pads home screen. Its like pushing the home button but I didn't. It only seems to do this when im in the app store or I tunes store. I have been using the chrome browser and other downloaded apps such as ebay just fine with out this problem occurring. Not sure about safari as I dont use it and use chrome instead. Um I don't think the home button its self is faulty because it works fine and as stated before this only happens when I am in the appstore or I tunes . I've only had this I pad 1 64gb wi-fi for a few days .. I got it off of ebay it was stuck in restore mode getting error code 1611. I was able to successfully Restore it with I tunes and it running ios 5.1. Seams to work great besides the problem being mentioned.

UDESEncrypt Errors when using the JAVA engine (NW IDM 7.0)

Folks,
I'm seeing an error when I use the uDESEncrypt function with the Java Engine in NW IDM SP2 Patch 3.
The error I am getting is:
runFunctionsInString($FUNCTION.encrPWD()$$) got exception
org.mozilla.javascript.EvaluatorException: uDESEncrypt: Key should be exactly 24 bytes long.
The code calling it is:
// Main function: encrPWD
function encrPWD(Par){
     //Example calling DSE internal function
     //UserFunc.uStop("Terminated by user");
     key = "C:\Program Files\SAP\IdM\Workflow\configs\KEY\keys.ini";
     OutString = UserFunc.uDESEncrypt(key, Par);
     return OutString;
I have also seen this error when using Patch 4.
Interestingly enough, the error does not occur when using the Windows Engine. Anyone else seeing this?
Thanks,
Matt

Hi Matthew,
Try to replace the '\' with '
key = "C:
Program Files
SAP
IdM
Workflow
configs
KEY
keys.ini";
Alternative approaches,
1) setting key empty and it will look into %DSE_HOME%\KEY\key.ini
which should be C:\Program Files\SAP\IdM\Identity Center\Key\key.ini on default installation path.
2) or setting the key to something like = 6D5A2AF59B1CDD7F9592484F178331C891537A3F9B91D362
   a 24 byte key...
Also when using DES you should ensure that in Identity Center underneath Options/General
you have encryption algorithm set to 3DES.
Normally if you intend to use this for password provisioning in IC you would also
on the identity store (for instance 'Enterprise people') underneath 'password policy' check
of for 'enable password provisioning.'
By doing so the MX_ENCRYPTED_PASSWORD with be set when operating through
workflow (3DES encryption version of the MX_PASSWORD) which allows you to obtain password
when provisioning to other target systems...

Intermittent errors when retrieving through smart view (11.1.2.5.210) in Oracle 11.1.2.3.500

We are getting the below errors when retrieving from huge smart view sheets for couple of our applications. We have increased the time out settings from the local registry, server registry, mod_wl_ohs file, Web logic console, http.conf, Essbase.properties. Also, increased the JVM from opmn.xml & setCustomParamsAnalyticProviderServices.bat. However we still face the error.
Note: this is an intermittent error and does not happen all the time.
Cannot connect to the provider. Make sure it is running in the specified host/port. Error(12152).

Also, we are facing retrieval performance issues after we upgraded to 11.1.2.3.500 after we migrated from 11.1.1.3.500. Has anyone faced this issue? if so, any suggestions in improving the retrieval performance (especially with MDX member formulas in ASO applications) in 11.1.2.3.500 version?

Is there a load balancer being used?
Does the issue common on both Shared and Private connection?

Getting error when using the option "Open Shared Calendar"

Hello Everyone,
I have created four calendars for our office all of them for booking meeting rooms.
Three of the four work just fine but the fourth is being a pain.
I'm running Exchange 2010 and all our clients are running Outlook 2007. I have re-created
the meeting room a couple of times just to make sure I hadn't missed anything.
When I, or another staff memeber tries to use the "Open a Shared Calendar"
withing Outlook 2007 in Calendar view, we get the below error.
Cannot display the folder. Microsoft Exchange is not available. Either there are
network problems or the Exchanges computer is down for maintenance.
Any ideas why I'm getting this error?
Thanks,
Sean

Hi Sean,
Could you please check the conference room type,whether it is an Auto Accept or Delegate Type.
checking the conference room type :
Get-CalendarProcessing conference room| fl *policy*
you may get the below results:
>Get-CalendarProcessing conferenceroom name| fl *policy*
RequestOutOfPolicy : {}
AllRequestOutOfPolicy : False
BookInPolicy : {}
AllBookInPolicy : True
RequestInPolicy : {}
AllRequestInPolicy : True
If "AllBookInPolicy : True" it mean it is an Auto Accept type and if "AllBookInPolicy : False" then it is Delegate type conference room.
If it is an Auto accept type then you should have Editor access on the concern room calendar to manage it and the same time if the room is an Delegate type you suppose to have Delegate access over the room.
To check whether you have permissions to access the room calendar.

Org.xml.sax.SAXException: Invalid element    error when using code in view project

I have a SOAP (RPC style) client bundled in a jar. It uses Axis1.4.
I have created a ADFBC model project with programmatic view & entity objects that uses this soap client for CRUD operations.
The Model project works fine when I run the Appmodule and a standalone java tester class.
This model project is then deployed as a library and included in a different ADF web application.
When running this application, I get the following exception for one method.
Has anyone faced this issue? Any idea what's going on?
Surprisingly, "dbAttributes" -the cause of the error is not even in the User class (or any other class in the entire application)!
I am using JDeveloper 11.1.1.5. Issue occurs in integrated wls.

org.xml.sax.SAXException: Invalid element in
I think this is a very common problem, and the sad thing is there are so many forums with no answers. I was getting this error because I was using client stubs generated by wscompile instead of wsdl2java. Once i used the stubs from wsdl2java, the error vanished****. I think its because the wscompile classes do not have property descriptors for each field in the response class. an example of such descriptors would be:
        typeDesc.setXmlType(new javax.xml.namespace.QName("https://ns.ns.btu", "LoginResponseData"));
        org.apache.axis.description.ElementDesc elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("sessionID");
        elemField.setXmlName(new javax.xml.namespace.QName("https://ns.ns.btu", "SessionID"));
        elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "int"));
        elemField.setNillable(false);
        typeDesc.addFieldDesc(elemField);The wsdl2java classes do have these descriptors for each field.

Error when using the template installer MI post installation process

Hi all,
I am busy to configure the Netweaver Administrator in order to create setup packages for mobile devices. This is a WAS 6.40 ABAP JAVA instance with mobile infrastructure.
I have installed the netweaver SR1 and upgraded abap and java to SPS18 afterwards.
Afterwards I used the template installer, I executed: MI post installation process.
But when I did this an error message occured on the following node:

Here after I followed manual: MI25 SPS18 inst newtech.pdf for configuring the NWA.
I checked the complete manual, but still the error message occurs, when I am using the template installer.
There is one more thing.
When I go to the NWA, to the Mobile Infrastructure node, allmost all subnodes give me the following error:

Does this error message relate to the other error message?
Please give me advise/hints/directions to solve this problem....
Your help will be appreciated!

Getting Deploy Error when using the WebDynpro Compiler

Hi,
I have a VC application which uses the RFC from R/3.
When i am using the Compiler as WEBDYNPRO, it is giving me Deploy Error as:
WebDynpro Compiler:
Portal request failed
(Model properties Namespace and Vendor are not specified for source archieve generator)
Also,
I checked the Iview property in the Portal but i am unable to find this properties.
Guide me when and where this Complier type is uesd..?
Thanks & Regards,

Hi,
I am unable to find this properties.
In the Model View i searched a lot.
I have another question also.
Do you know how to refresh the table from the RFC.

Error when using the RelationManager: WdfError

Hi,
I'm trying to use the IRelationManager to get Relation between rooms. I tried to retrieve the manager using:
IRooms roomsAPI = (IRooms)PortalRuntime.getRuntimeResources().getService(IRooms.PORTAL_SERVICE_ID);
roomsApi.getRelationManager();
Unfortunately this does not work most of the times, I get a nullpointer back from the roomsAPI. Funny thing: sometimes it works, but mostly not...
Also, I can not delete rooms or view the room-relations using the corresponding standard-portal IViews, I'm getting an excpetion:
com.sapportals.wdf.WdfError
Does anybody has a clue what is causing this strange behaviour of the portal?
Thanks and regards,
Jan Hempel

This may be a bug in the expression validation, decode is valid in an expression operator always when Set Based code generation only is used (you may get errors if row based is used), if you configure the mapping to set based only code generation mode and default operating mode then try deploying the mapping you should be OK. Otherwise you build an expression that is valid SQL (set based) and PLSQL (row based), the CASE statement will give you this

Hi,
It worked for me, I dont for your case.
Mine syptom:
When filtering by using the context menu's "keep filter" and then filter by using a "Hierarchy Web Item" (based on Calendar month),
then I was getting the message <i>"System error in program CL_RSR_WWW_RENDERER and form SUBMIT_FILTER"</i>
It is solved by adding a "Filter Web Item" to display the filter values. If you dont want that object in your report, you can hide it.

Is anybody else struggling with an intermittent connection when using the Magic Mouse/Trackpad ONLY on Boot Camp?

Hi,
I've seen thousands of posts about Bluetooth connection issues and interference and stutter/lag for both the Magic Mouse and Trackpad (affecting both Mac OS X and Windows under Boot Camp) but my problem is different.
To summarise my setup, I use:
- Retina MacBook Pro (lid closed or open, doesn't make a difference to this problem)
- Thunderbolt Display
- Wireless Keyboard
- Magic Trackpad (have also tried a Magic Mouse and experience similar issues to the Trackpad)
And in Mac OS X, everything works perfectly. The keyboard and trackpad work smoothly when I'm 6-7 metres from the machine, whether or not the laptop lid is open or closed, and whether or not the Thunderbold Display is connected.
But on to my problem: the bluetooth connection is incredibly unreliable/intermittent when in Windows (I run Windows 7 64-bit and Boot Camp 4.0, and got both devices connected without any trouble via Bluetooth).
But during usage, the cursor stutters/lags frequently, and tap to click (when enabled) seems to get triggered by mistake all the time (even when I'm not touching the Trackpad or even at the computer, clicks get registered).
The Wireless Keyboard is perfect, and works well 5 metres from the machine. The Mouse and Trackpad, though, don't even work reliably when they are 6 inches from the machine. The built-in trackpad on the laptop works perfectly too, in Windows and Mac.
I spent a week assuming I was suffering from Bluetooth interference, so I tried:
- using the laptop with the lid open
- removing the Thunderbolt display completely and trying the Magic Trackpad
- repositioning items on my desk
- disabling wifi
All of these adjustments made minor differences to how good/bad the Trackpad was, but none came close to fixing the problem or making it work as smoothly as under Mac OS X. It was only after doing all of this that I realised perhaps it was just a Apple driver for Windows issue, so I booted into Mac OS X and tested everything out, and sure enough, it's all perfect. But back into Windows, the Trackpad doesn't work reliably at all.
Obviously, the hardware is not at fault, and I assume the signal strength doesn't vary between operating system (why would it?) so I'm left believing this must be a driver issue. The TrackPad and Magic Mouse drivers have been out for a couple of years, so I'm surprised they can still be this bad. I tried both the latest driver from Boot Camp 4.0 (3.2.0.0) for the Trackpad, and also the older one from Boot Camp 3.2 (3.1.0.7) and both are equally bad for me.
So my question is: has anybody else struggled with using the Trackpad (or Magic Mouse) with Boot Camp 4.0 and Windows 7 64-bit, whilst finding it to be perfect under Mac OS? I haven't found many posts complaining about the Windows driver, which is why I assumed it was an interference issue. But I'm almost sure it isn't, having spent 2 weeks investigating.
Any thoughts/suggestions/answers much appreciated!
Kyle

SOLVED!
After much testing, I have found the cause of lagging/jumpiness on the Bluetooth Magic Mouse and Magic TrackPad in Boot Camp. Hopefully this will help others:
The drivers for the Broadcom 802.11n Wireless Adapter have a setting called "Bluetooth Collaboration" that is Disabled by default. Enabling this option removes the problem instantly. My Magic Trackpad now works flawlessly, even if I stand 6 metres from the machine. It now works just as well as under Mac OS. The setting can be found under:
Control Panel > Device Manager > Network Adapters > Broadcom 802.11n Network Adapter (right click and choose "Properties". Under the "Advanced" tab, highlight the setting named "Bluetooth Collaboration", then change it to Enable. Then click OK.
I narrowed the problem down to the wireless card by disabling ALL startup services and processes for Windows, then re-enabling one by one. As soon as I enabled the Windows Wireless Service, the problem came back. Similarly, disabling the Wireless Card inside the Network and Sharing Center (or Device Manager) removes the problem. This led me to believe it must be a driver issue with the wireless card, since the problem didn't occur with the Magic TrackPad under Mac OS, or on my mother's Windows 7 64-bit computer. So when I went into the Driver Properties to check for an update, I found this setting about Bluetooth Collaboration.
I really hope this helps others trying to use Bluetooth devices under Boot Camp. All Apple notebooks use the Broadcom card (and have done for years), so this driver is installed for almost anybody using Boot Camp on an Apple notebook. I'd assume this problem would affect anybody using Boot Camp + wifi + a Bluetooth device.

Error when using the variable System::ErrorDescription

HI All,
When I try to use the variable System::ErrorDescription I get the following error:
The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.
Do I need to declare it or it's a variable that always is available to get exceptions from the execution states?

if this is in a Script Task then:
- add the variable in the Script task property ReadOnlyVariables list
- in the Script Code refer to it as
string ErrorDesc = (string) Dts.Variables["System::ErrorDescription"].Value;

500 internal server error when using the web interface

I've created several tables in Visual Studio, and I'm using a .NET backend for my mobile services.
The table code looks something like this...
using Microsoft.WindowsAzure.Mobile.Service;
namespace AzureService.DataObjects
public class Country : EntityData
public string Name { get; set; }
I then added a scaffolded item to generate the controller for my table, then published.
I then went to my azure service, flipthechipservice.azure-mobile.net, and tried to run the default POST with default data.
I then get back a popup, which looks like the following...
Now what baffles me is I have already created another table, called 'Call', which has exactly the same 'Name' field as the above Country table, yet the Call POSTs work.
I then tried creating another table, with a Name field, and I get the 500 error again.
How can this be possibly happening? Nothing is different, and now I get 500 errors?
This makes no sense.
Thanks

Thank you, I looked at the logs, and this is the error...
System.NotSupportedException: Model compatibility cannot be checked because the database does not contain model metadata. Model compatibility can only be checked for databases created using Code First or Code First Migrations.

I looked this error up, and tried
this proposed solution on StackOverFlow
I changed the line of code in my WebApiConfig Register() method from...
Database.SetInitializer(new MobileServiceInitializer());
to
Database.SetInitializer<MobileServiceContext>(new DropCreateDatabaseIfModelChanges<MobileServiceContext>());
I also have this in my WebApiConfig...
public class MobileServiceInitializer : DropCreateDatabaseIfModelChanges<MobileServiceContext>
protected override void Seed(MobileServiceContext context)
base.Seed(context);
My understanding is that the database should drop and create if the model changes? So why is this not happening?
I then tried another solution, and changed DropCreateDatabaseIfModelChanges to DropCreateDatabaseAlways. I still get an internal error. Then the logs show this problem...
System.Data.SqlClient.SqlException (0x80131904): Cannot open database "master" requested by the login. The login failed.
Login failed for user 'QEOzFqAnDXLogin_flipthechipservice'.

As an additional question, how do I re-generate my local SQL database when debugging on my local PC's web browser? I deleted the database, but can't seem to get it back?
Thanks
