Connecting to a PI Data Historian with xMII 12.0

I'm trying to connect to a PI data historian from xMII 12.0. The PI connection was running OK on my xMII 11.5 server with the UDS 2.5 framework and PI UDS installed on the PI server. The UDS 2.5 stuff is still running on the PI server but I'm not sure what I need to do on the xMII 12.0 server to make the connection.
Thanks!
David

Thanks, Jeremy. The data server info came over from 11.5 to 12.0 during the migration but, while I can still make a connection and pull in data with my 11.5 development server, I get an 'Error' status with my 12.0 development server.
Any ideas?

Error of data exchange with an external server

Help to understand.
There is a client which is connected to a server, data exchange with a server is realized through a method sendData(byte[] sendbytes, String code, int resplen)

Why the specified method normally works in Tomcat a server,

I can not understand in what the reason ...

José,
The 6036E User Manuals gives the best definition of the STARTSCAN, TRIG, and CONVERT* signals as well as their relationship to eachother. See 4-20 Connecting Timing Signals of the User Manual for this information as well as timing diagrams.
NI 6034E/6035E/6036E User Manual

You are correct that configuring your board for external timing is just as simple as connecting your external clock to a PFI line and using it as the STARTSCAN signal. The clock output of your GPS receiver will now be defining when scans are perform on your 6036E due to the synchronization between the two devices. The only synchronization issue you may encounter is
propogation delay. This will be a factor of the cable length connecting your GPS clock to the 6036E.

Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of '

When I deploy the cube which is sitting on my PC (local) the following 4 errors come up:
Error 1 The datasource , 'AdventureWorksDW', contains an ImpersonationMode that that is not supported for processing operations.  0 0
Error 2 Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Adventure Works DW', Name of 'AdventureWorksDW'.  0 0
Error 3 Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Customer', Name of 'Customer' was being processed.  0 0
Error 4 Errors in the OLAP storage engine: An error occurred while the 'Customer Alternate Key' attribute of the 'Customer' dimension from the 'Analysis Services Tutorial' database was being processed.  0 0

Sorry hit the wrong button there. That is not entire solution and setting it to default would work when using a single box and not in a distributed application solution. If you are creating the analysis database manually or using the wizard then you can
set the impersonation to your heart content as long as the right permission has been set on the analysis server.
In my case I was using MS Project Server 2010 to create the database in the OLAP configuration section. The situation is that the underlying build script has been configured to use the default setting which is the SQL Service account and this account does
not have permission in Project Server I believe.
Changing the account to match the Project service account allowed for a successful build \ creation of the database. My verdict is that this is a bug in Project Server because it needs to include the option to choose impersonation when creating the Database
this way it will not use the default which led to my error in the first place. I do not think there is a one fix for all in relations to this problem it is an environment by environment issue and should be resolved as such. But the idea around fixing it is
if you are using the SQL Analysis server service account as the account creating the database and cubes then default or service account is fine. If you are using a custom account then set that custom account in the impersonation details after you have granted
it SQL analysis administrator role. You can remove that role after the DB is created and harden it by creating a role with administrative permissions.
Hope this helps.

Impossible to use "Connect to Data/Service" with BlazeDS

Hi everybody, I'm work on FB4 since 3 weeks, but I have big problem to use "Connect to Data/Service" with BlazeDS. each time I try to use it, it's the same question " You must define a BlazeDS server" and when I define the BlazeDS server and .war, I have the question again... You must define a BlazeDS server
I work on Mac OsX Leopard and his java 6.
Thanks for your help

Hi,
Thanks for your feedback
Can you please tell us which version of Flash Builder4 and BlazeDS you are using.?
Also, can you try the same workflow by using the turnkey version of BlazeDS(4.0.0.11428) with Flash Builder BETA2 build.

Business View data foundation with dynamic data connection hangs

We are running Business Objects XI 3.0 with Crystal Reports 2008 and Business View Manager 12.0.0.683. In the Business View Manager tool, when I try to open a data foundation that uses the ACD Dynamic data connection, it hangs with the hourglass icon. I have left it trying to open for at least an hour before killing the Business View Manager with the Windows Task Manager. Data foundations using a static connection open fine as do the elements and views based on the data foundation with the dynamic connection. The static data connections included in the ACD Dynamic connector point back to an Oracle Server. Any ideas how to get the data foundations to open so I can edit our custom business views?
Thanks,
Kathy

I created some Views to pull the data in from the Oracle side.

Connecting XML files with xMII

Hi,
i want to connect xml file (say one.xml having table name and price) with xMII. how can i do it? by using TAG query? what is the simulatorTag.xml?
- senthil

Senthil,
Save your .xml file in your local system
Open Business Logic Editor and under WEB you can find xmlLoader.
Right Click and configure the path of the xml file in source URL.
This will load your xml file and all the rowsets will be available for further manipulation...
Tag Query is normally used to query a Tag type database like simulator..
Hope this helps,
Ajitha

How to connect Data Services with microsoft SQL/ Steps

Dear All,
i attend to connect the SAP BO Data Services to Microsoft SQL.
1. Is there any document which explains the steps to follow?
2. Is there any document how to build a prototyp
Thank you.
Pat.

Hi Aditya,
You can use a datastore of type ODBC using the IBM Client Access driver or the DataDirect driver that comes packaged with Data Services. There is a sticky thread on downloading the DataDirect driver. There is also another option to connect with the Attunity driver for the AS400. You cannot use the DB2 UDB drivers to connect to the AS400 V6R1.

Getting 401 error while creating a Report Data Source with MOSS 2010 Foundation

I have setup SQL Server 2008 R2 Reporting Services with SharePoint 2010 Foundation in SharePoint integrated mode. SharePoint Foundation is in machine 1 whereas SQL Server 2008 R2 and SSRS Report Server are in machine 2. While configuring Reporting
Services - Sharepoint integration, I have used Authentication Mode as "Windows Authentication" (I need to use Kerberos).
My objective is to setup a Data Connection Library, a Report Model Library, and a Reports Library so that I can upload a Report Data Source, some SMDLs, and a few Reports onto their respective libraries.
While creating the top level site, "Business Intelligence Center" was not available for template selection since SharePoint Foundation is being used. I therefore selected "Blank Site" as the template.
While creating a SharePoint Site under the top level site, for template selection I again had to select "Blank Site".
I then proceeded to create a library for the data connection. Towards this, I created a new document library and selected "Basic page" as the document template. I then went to Library Settings for this newly created library and clicked on
Advanced Settings. In the Advanced Settings page, for "Allow management of content types?" I selected "Yes". Then I clicked on "Add from existing content types" and selected "Report Data Source". I deleted the existing
"Document" content type for this library.
Now I wanted to created a Data Connection in the above Data Connection library. For this when I clicked on "New Document" under "Documents" of "Library Tools" and selected "Report Data Source", I got the error "The
request failed with HTTP status
401: Unauthorized.".
Can anybody tell me why I am getting this error?
Note: I have created the site and the library using SharePoint Admin account.

Hi,
Thank you for your detailed description. According to the description, I noticed that the report server was not part of the
SharePoint farm. Add the report server to the
SharePoint farm and see how it works.
To join a report server to a SharePoint farm, the report server must be installed on a computer that has an instance of a SharePoint product or technology. You can install the report server before or after installing the SharePoint product
or technology instance.
More information, see

Data Federator with BW 3.5

Hi Experts,
We are using Data Federator and connected to our Client BW 3.5 Oracle Data base directly.
We were looking to connect to below Cube and Ods tables
InfoProviders Table Names
InfoCube ZSD_BILDP /BIC/EZSD_BILDP, /BIC/FZSD_BILDP
ODS Object ZDP_O04 /BIC/AZDP_O0400
ODS Object ZDP_O03 /BIC/AZDP_O0300
ODS Object ZDP_O02 /BIC/AZDP_O0200
ODS Object ZDP_O01 /BIC/AZDP_O0100
But we are not able to see the above tables in Data Federator and all the tables we are seeing is
SAPBIW.?22FBIO?22fsMAT_ITEM
SAPBIW.?22FBIO?22fsMAT_PLANT
Can you suggest how can I see the Cube and Ods Tables directly in DF Designer???
P.S: I did worked with DF in BI 7.0 with my previous Client and it has got the RSDRI_DF_* Functional Modules in SE37, but to new Client we have requirement to use DF with BW3.5 which is becoming troublesome to get to Cube and Ods tables.

Hi Ingo,
Thanks for responding.
We are directly connecting to BW Oracle Data Base and not the BW/BI integration as we don't have the DF* Functional
Modules present in BW 3.5
Find below couple of Connection Parameters using which I am connecting to BW from DF Designer.
Data Source Type -- Oracle
Defined resource -- jdbc.oracle.oracle10
Host name        -- xxx.xx.xxx.xx(not specifying here due to security)
Port             -- 1xxx

Excel SSAS Tabular error: An error occurred during an attempt to establish a connection to the external data source

Hello there,
I have an Excel report I created which works perfectly fine on my dev environment, but fails on my test environment when I try to do a data refresh.
The key difference between both dev and test environments is that in dev, everything is installed in one server:
SharePoint 2013
SQL 2012: Database Instance, SSAS Instance, SSRS for SharePoint, SSAS POWERPIVOT instance (Powerpivot for SharePoint).
In my test and production environments, the architecture is different:
SQL DB Servers in High Availability (irrelevant for this report since it is connecting to the tabular model, just FYI)
SQL SSAS Tabular server (contains a tabular model that processes data from the SQL DBs).
2x SharePoint Application Servers (we installed both SSRS and PowerPivot for SharePoint on these servers)
2x SharePoint FrontEnd Servers (contain the SSRS and PowerPivot add-ins).
Now in dev, test and production, I can run PowerPivot reports that have been created in SharePoint without any issues. Those reports can access the SSAS Tabular model without any issues, and perform data refresh and OLAP functions (slicing, dicing, etc).
The problem is with Excel reports (i.e. .xlsx files) uploaded to SharePoint. While I can open them, I am having a hard time performing a data refresh. The error I get is:
"An error occurred during an attempt to establish a connection to the external data source [...]"
I ran SQL Profiler on my SSAS Server where the Tabular instance is and I noticed that every time I try to perform a data refresh, I get the following entries:
Every time I try to perform a data refresh, two entries under the user name ANONYMOUS LOGON.
Since things work without any issues on my single-server dev environment, I tried running SQL Server Profiler there as well to see what I get.
As you can see from the above, in the dev environment the query runs without any issues and the user name logged is in fact my username from the dev environment domain. I also have a separated user for the test domain, and another for the production domain.
Now upon some preliminary investigation I believe this has something to do with the data connection settings in Excel and the usage (or no usage) of secure store. This is what I can vouch for so far:
Library containing reports is configured as trusted in SharePoint Central Admin.
Library containing data connections is configured as trusted in SharePoint Central Admin.
The Data Provider referenced in the Excel report (MSOLAP.5) is configured as trusted in SharePoint Central Admin.
In the Excel report, the Excel Services authentication settings is set as "use authenticated user's account". This wortks fine in the DEV environment.
Concerning SecureStore, PowerPivot Configurator has configured it the PowerPivotUnnattendedAccount application ID in all the environments. There is
NO configuration of an Application ID for Excel Services in any of the environments (Dev, test or production). Altough I reckon this is where the solution lies, I am not 100% sure as to why it fails in test and prod. But as I read what I am
writing, I reckon this is because of the authentication "hops" through servers. Am I right in my assumption?
Could someone please advise what am I doing wrong in this case? If it is the fact that I am missing an Secure Store entry for Excel Services, I am wondering if someone could advise me on how to set ip up? My confusion is around the "Target Application
Type" setting.
Thank you for your time.

Hi Rameshwar,
PowerPivot workbooks contain embedded data connections. To support workbook interaction through slicers and filters, Excel Services must be configured to allow external data access through embedded connection information. External data access is required
for retrieving PowerPivot data that is loaded on PowerPivot servers in the farm. Please refer to the steps below to solve this issue:
In Central Administration, in Application Management, click Manage service applications.
Click Excel Services Application.
Click Trusted File Location.
Click http:// or the location you want to configure.
In External Data, in Allow External Data, click Trusted data connection libraries and embedded.
Click OK.
For more information, please see:
Create a trusted location for PowerPivot sites in Central Administration:

Another reason is Excel Services returns this error when you query PowerPivot data in an Excel workbook that is published to SharePoint, and the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis
Services (PowerPivot) service is stopped. Please check this document:

Finally, here is a good article regarding how to troubleshoot PowerPivot data refresh for your reference. Please see:
