Connecting HiFi to an FM source

Is it possible to use an optical cable with any device that receives an FM signal to connect to the HiFi? I simply want the option to listen to the radio through the HiFi. Also, has anyone had an opinion on sound quality using a 3.5mm to 3.5mm cable? Thanks for your interest!

Thanks Mitch. What about this?

Can I find that mini to mini cable anywhere? I've never come across one.

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.
Regards,
P.

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:
http://msdn.microsoft.com/en-us/library/ee637428.aspx
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:
http://technet.microsoft.com/en-us/library/ff487858(v=sql.110).aspx
Finally, here is a good article regarding how to troubleshoot PowerPivot data refresh for your reference. Please see:
Troubleshooting PowerPivot Data Refresh:

Connection verification failed for data source using mySQL

Hi,
I having problem with mySQL datasource and getting the above error. This is only happening in our staging server. We are using ColdFusion 8 running JRUN4 and trying to connect to mySQL v 5.1.41. I tried adding DSN from my localhost using ColdFusion 9 developer edition and I am able to connect without error.I know that mysql server, username & password is valid. I can access the mysql also using mySQL gui tool from different pc and it works fine. I'm believe that this has something to do with mySQL driver? Can somebody shed some light on how can I fix my DSN connection problem? Thank you.
here's the error:

Also make sure your firewall has the required port open (1433
default) and if you are running 2003 on the SQL box, especially if
you ran the security Wizard, make sure the IPSec is allowing the CF
box to communicate with it, and vise verse.

Regarding Making DB Connect Delta Capable with external Sources

Hi Everyone!
Although as standard DB Connect does not support Delta, this much I have understood. Lately I came across an article from Shreekant Shiralkar and Bharat Patel, BW System Managers, Bharat Petroleum, India in an old BW Expert Article... I have understood that this is from BW 3.0 upwards. Can this be applied to BI 7.0? The Title of the article is "Make DB Connect Delta Capable with External Sources"
Chetan? Edwin? Olivier? Anil? Sandeep? Moderators?
Regards,
Philips

Hi Philips,
I didn't read this article but I'll expose what we have implemented here.
All data coming from non SAP systems are loaded into what I named a "pre staging" database (PSDB) prior extracted to BW. This PSDB is nothing else than a simple, cheap, easy to manage MSSQL server 2000.
Our BW has this PSDB system declared as DBConnect source system.
In few words, we do data cleansing, preparation, formatting in this PSDB when any non SAP data shall be loaded in SAP BW. In addition, we use this machine to perform any R/3 datamigration required for new Rollouts.
Coming back to the delta handling: we don't handle deltas with this DBConnect source system because SAP BW doesn't consider it as delta capable natively.
We develop function modules extractors having the MyBW as source system. MyBW then "think" it is a SAP delta capable source system and we can then setup our MyBW DataSources with any kind of delta type by changing manually the core table ROOSOURCE.
The extractor itself does many things because all structures are handled dynamically and some part of the extractor coding itself is generated on the fly.
The extractor also creates temporary stored procedure directly in the PSDB so that only deltas are delivered to BW.
The core of the extractor, I think everyone would agree, is the OPEN CURSOR statement. The OPEN CURSOR in our case is simply done within an EXEC SQL having our PSDB connection open.
I could discuss this approach at length but we are now running this for more than 3 years (of course a certain effort has been done initially) to our full satisfaction.
I am now finalizing the next "generation": having the PSDB server posting itself, deltas to the MyBW TRFC queue, emulating some how a LO/LIS DataSource.
hope this shed light (at leas mine...)

Connection verification failed for data source on port 1433

Hi,
Is that SQL Express edition? If so perhaps TCP protocol is not enabled. Is Windows firewall turned on? Check port 1433 is open.
Normally you would not create a datasource to apache port 8500, that is a web server not database server port.

Excel-2007 cannot connect to Oracle ODBC data source, Control Panel can.


I cannot make an ODBC connection from Exce-2007 to Oracle work. I am an expert Excel and VBA user (since 1994) and I have frequently used Excel to access ODBC databases, including Oracle (I have done this with Excel-2003 both with worksheet queries and have written VBA ADO-connection routines). And even though in Excel-2007 a worksheet ODBC query is supposed to be easier to create than in previous version of Excel, my connection fails. Any suggestions and all help are welcome and much appreciated.
DETAILS


1) What is my system? I am using Excel-2007 on Windows Vista x64 and Oracle server v.11g on my computer (all this is on my computer, no network issues).
2) Why use Excel with Oracle at all? I use Excel-2007 to access Oracle rather than Access-2007 (or any other application like TOAD, etc.) because I do engineering calculations with the data stored in Oracle. These calculations are easier done in Excel (I suppose that one alternative to this could be to use some sql or Access to get the data from the database, then store it as plain vanilla CSV file, then open this file in Excel, then do the math (the math involves complex optimisation algorithms), then save the results as CSV, then use some sql or Access to put the data back into the database. Howwever this does not strike me as a quick or neat solution. And after all Excel has been designed to access ODBC databases, so why not use it?)
3) What do I do in Excel-2007 that won't work? I create an ODBC link to Oracle that does not work. In Excel-2007 this is straightforward:

<ul>
<li>define an ODBC connection (Data tab --> From other sources --> From data connection wizard);</li>
<li>define a query on the worksheet -- that's it, this is all!</li>
</ul>

I start with creating an ODBC connection:
a) I choose an ODBC data source type: ODBC DSN
b) Excel-2007 displays the list of the available ODBC data sources. I see in it my Oracle database name and I select it.
c) Excel-2007 displays the Data Link Properties:
- the "Provider" has a list of the OLE DB drivers with preselected "Microsoft OLE DB Provider for ODBC Drivers". I keep this default selection.
- the "Connection" tab has a connection string "DSN=<my database name>" which I keep, it also has fields for the user name and the password, which I fill with the correct credentials.
- Finally there is a button "Test Connection", which when I click produces the following error message:
"Test connection failed because of an error in initializing provider. 
Unespecified error"

4) Additional food for thought:
a) In the above walk-through the only data, which I type, are the user name and password, everything else is selected from lists offered by Excel-2007, hence any possibility of typos being the cause of the problem can safely be discarded.
b) I can test the ODBC driver in the Control Panel and it shows that it can connect to the Oracle database:
- in Control Panel --> Admin Tools --> Data Sources (ODBC) on the "User DSN" tab I can see the list of the available ODBC data sources (same list as in Excel-2007, point 3b above) with the name of my database in it;
- selecting the name of my database from the list of the sources and clicking "Configure" button opens a tab with Data Source Name (same as in Excel-2007), TNS Service Name and User ID. I enter <user name>/<password> and click "Test Connection" button. A message "Connection successful" appears (just for a test I enter incorrect user credentials and "Unable to connect" message appears)
BOTTOM LINE


The procedure for using an ODBC connection from Excel is very simple, in the past I have created and used such connections numerous times with Excel-2003 and earlier on Win-XP and earlier. But now on Excel-2007 and Vista-x64 I cannot make it work.
Also, testing an ODBC connection driver is really easy and simple to be done in the Control Panel. There testing the same ODBC connection, which fails in Excel-2007, results in success.
I am frustrated by the simplicity of the problem and yet the persistant error. I have lost now two full days in failed attempts to make the simple procedure work and in searching the internet for answers.
All help is highly appreciated <img class="emoticon" src="images/emoticons/happy.gif" border="0" alt="" width="16" height="16" />,

Did you find the solution to your problem?
If not, I think I may know.
Excel 2007 is a 32-bit application.
When installing 32-bit applications in a 64-bit environment, the "default" location is:
C:\Program files (x86)\...
Excel then launches from this location.
However, when it connects to Oracle and passes the name of the calling program, Oracle attempts to "interpret" the value of (x86) as if
the value within the parenthesis are being passed as a reference. Of course, iOracle doesn't find anything, so the result is (),
and then it cannot return the connection info back to the calling application.
I corrected it by installing Excel in C:\Program Files\, and once launched from that location, it works the same as on the 32-bit machines.
However, at my location, they are FORCING Excel to be installed in the(x86) location.
What I'm trying to discover now is:
Is it possible to flag Oracle to NOT process the embedded variables?
Or, is it possible to assign a variable in Oracle such that x86 = "(x86)", so that the end result is viable?
Have you had any luck with your installation?
thanks,
Paul

Missing Connection Types in Report Data Source Properties

I am running three installations of SharePoint 2013 with SQL 2012 for Business Intelligence, with Kerberos working.
I have been having intermittent issues with SQL Reporting Services in a multi-server configuration, but finally had it working in all three environments. We discovered many of our issues were caused by master page customizations which we have now disabled
temporarily while we work on function issues.
However, we started having a new problem with Reporting Services on just ONE of the environments, and we are not sure what happened. Most everything appears to still be working, except Reporting Services. I have verified that features are enabled
in both the farm and the site collection, as well as insured managed content types are being allowed on the target document libraries. I also verified the Reporting Service properties and database connections. However, I have found two clear symptoms
which I can find no other information regarding (in logs or in online searches):
1) If we try to create a new "Report Data Source" using the SharePoint UI, it will open a new Data Source Properties window, but in the "Data Source Type" field, there are no values available for me to select my connection type (e.g.,
Microsoft SQL Server).
2) In Central Administration, while administering the Reporting Services Service Application, I can manage a majority of the settings, including System Settings, Manage Jobs, Key Management, etc. However, if I click on the link for "E-mail Settings,"
I get the dreaded "Sorry Something went wrong screen," with an error saying that "Object reference is not set to an instance of an object."
So I am hoping someone has an idea of where I can look for additional information on this issue, or even better, knows what I am missing to get Reporting Services functional again in this environment!
Thanks in advance for any help provided.
Elohir

However, we started having a new problem with Reporting Services on just ONE of the environments, and we are not sure what happened.
Hi Elohir,
I assume you are installing Reporting Services SharePoint mode for SharePoint 2013, you need to:
1. Install "Reporting Services – SharePoint" and "Reporting Services add-in for SharePoint Products" on the SharePoint server that the SSRS service will run on. All other SP servers only need the "Reporting Services
add-in for SharePoint Products."
2. Run the Insall-SPRSService and Install-SPRSServiceProxy on Central Admin and SSRS server.
3. Start SSRS Service only on desired SSRS servers.
http://msdn.microsoft.com/en-us/library/jj219068.aspx
Since the issue occurs only to one of the environments, please provide more information about your multi-server configuration, and point out the server where the issue occurs.

HT1414 My iphone 4s is stuck in the CONNECT TO ITUNES screen (appears everytime i turn it on or connect it to a power source)

It all started when i tried to update to iOs 6 but then, my battery drained. I charged it (va power source) and waited for the red battery bar icon to appear. However, it did not appear. Instead a CONNECT TO THE ITUNES screen appeared even when i'm not connected to a laptop. It was stuck there. When i turned it off and on again, the same screen appears even my iphone is not connected to any kind of power source.
What should i do?
i tried turning it off and on again
tried restarting it by pressing the wake button and the home button (a lot of times already), still the same
i tried restoring it (noe effect)
pls help me
I bought the iphone in another country, i'm not sure if apple can repair it in my country

i tried to connect it but it didnt work...nothing changed...

Using several data connections in one SSIS data source?

I am loading data from several SQL Server 2012 databases into a datamart. Currently, I am simply using sql sources and destinations for that. However, some of the queries require JOINs between the source databases. Therefore I currently refer to the databases
within the command text of the sql source, e.g.
SELECT t1.Field, t2.Field
FROM [server1].[db1].[dbo].[table1] t1
JOIN [server1].[db2].[dbo].[table1] t2 ON t1.Table1Id = t2.RemoteTable1Id;
This is flawed, since all the sql commands have to be changed if the database or server names change. It would be far better to refer to connections which can be changed on package level and my question is how to get that done.
One way I can think of to get that done is to use several sql source queries and join the data with SSIS join operations. For that all current data flows need to be reworked and I am unsure about the performance when joining large databases compared to the
performance of a single t-sql query.
The other approach would be some dynamic sql stuff which I want to avoid whenever possible. However, if it was possible to use a parameter to insert server/database into the sql command somehow, then that could be an option.

Whatever you're doing now is a bad practice inside SSIS. You should be using data flow tasks for this if data come from different sources and use connection managers pointing to each of them. You add these connection properties as config items which will
enable you to change them from outside package based on your environment
If performance is your concern you can go for staging approach where you bring deltas(changes) alone on daily basis and then use it in the comparisons with destination tables using MERGE or T-SQL for set based processing. You need to have audit columns in
your tables for this though.

Hi can i connect hifi digital and my home wifi to airport express.

Hi i have been thinking about adding my hifi and sony digital TV to my home network which consist of three mac computers and has a wifi internet connection. What are the advantages of using airport express over bluetooth hardware. Using the male single plug on the airport express what is the sound clarity like from my Iphone. At present it is not very good using earphone jack on my Iphone 4 to Hifi. Will it improve with airport express. What is the difference between airport express and extreem. Lots of questions maybe a few answers. thankyou Paul

Re Airport Express. I use one of these to play Apple Lossless files through my hifi. The stereo connector on the Express is capable of both analogue and digital output. To use the analogue output - which is the same from standard stereo equipment like CD Tape players, and iPhone headphone connector, use the standard plug with the appropriate connectors for your amplifier. To use the digital output, you will need to use a toslink cable - AND your amplifier will need to have a digital in port. The toslink will need to have a connector that fits inside the connector on the Express ( it is a bit longer than the usual stereo / headphone jack and allows the laser light inside the Express to shine down the cable to the amp - which may have a slightly different connector and require an attachment to the end of the tosling cable. If your amp does not have a digital connector - my does not - then you could purchase a stand alone DAC that takes the laser light and converts it to analogue output. These can vary in price substantially but MAY givea better sound - depending on the quality of the DAC and the quality of the amp. The Express has a built in DAC that is used if you use the standard stereo cable, and by-passed if you use the toslink cable.
Quality
The difference in quality will depend on the type of files you are using, your amp and your speakers.
MP3 files may not sound any different, but Apple Lossless or FLAC files which are much higher quality MAY - or MAY NOT - sound better using toslink cable and the DAC compared to using the analogue output and standard stereo cable from the Express.
Personally, I use Apple Lossless files from iTunes and the analogue output from the Express into Rega Amp and Royd Speakers and I'm very pleased with the sound. I have considered using an stand alone DAC but feel the extra expense is not worth it in my case. You could start with the same setup and see how it sounds to you. The quality is difinitely very good and you can add the toslink cable and DAC later. The latest Airport Express may contain an even better DAC than earlier versions so may sound even better.
If you have an iPhone, you can use Apples Remote app to control iTunes on your Mac, to choose music,change track, change volume etc. This all works over the wifi network. You can also stream music directly from your iPhone - or your friend's iPhone - to the Express over the wifi network.
I have my MacBook Pro in my office space, 15 metres away in the next room, my Express and stereo in the living room and my iPhone in my hand on the couch and I'm delighted with the flexibility and the sound.
I have no experience with bluetooth for sound.
