Sharing target application between two external data connections

If I want to create two BDC connections to two separate external systems (let's say one is for HR system and one for IT admin system), can I use the same Target Application in the secure store service section if both of them use the same authentication?
Let's say both external systems allow access for 'admin1' user. Then, when setting up the external data connection I use 'impersonate windows identity' and create a target application in secure store service to map a set of users to that 'admin1' account.
When I create these two external data connections can I specify the exact same 'target application' or should I create two separate ones, one for each external system?
thanks,

Hiya,
If you want to use impersonate, you do not need to use Secure store. Impersonation is granting the service account delegation permissions. This is part of the Kerberos authentication protocol, which needs to be configured separately.
All secure store does, is to store a set of credentials encrypted. These stored credentials can be used wherever, as long as they are valid.

Sharing a shared network variable between two PC's connected to a network

Sharing a shared network variable between two PC's connected to a network
Surely this shouldn’t be so difficult! I have a little LabVIEW program running in the background of PC1. The exe’s task is to collect and send OPC variables held on a SCADA system and convert them to shared network variables (as I thought that they would be easy to share over a network, easier than the nasty OPC and DCOM issues). I have PC2 which runs measurement studio and I have created a nice test VB program which either writes or reads the network variables which are on PC1. The PC1 collection software is working perfectly and when I change the values on the SCADA system I can see the network variable change on ‘NI Distributed System Manager’. I When I look at ‘NI Distributed System Manager’ on PC2 I can’t see PC1 on the list and when I use the basic measurement studio code below to read the network variable it times out at the TestVariable.connect() line.
Ok so what do I need to do to read a shared network variable sat on PC1 from PC2 on the network
Public Class Form1
Private WithEvents TestVariable As NetworkVariableSubscriber(Of Double)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TestVariable = New NetworkVariableSubscriber(Of Double)("\\192.168.58.139\Test\TestVariable")
TestVariable.Connect()
End Sub
Private Sub TestVariable_Data_Updated(ByVal sender As System.Object, ByVal e As NationalInstruments.NetworkVariable.DataUpdatedEventArgs(Of Double)) Handles TestVariable.DataUpdated
TextBox1.Text = e.Data.GetValue
End Sub
End Class

Sorry lost all the formatting

Is it possible to set up a backup between two external drives

Is it possible to set up a backup between two external drives?
i use time machine to back up my imac onto an external 2T.
i also have two external 3T drives. i am looking for redundancy of data, tried software RAID and it failed. i also see some limitations with RAID that a backup would avoid.
thanks for sharing your expertise.
be well,
tony

so thanks to all of you, particularly rkaufmann87 i have decided to stop the plan of setting up a software RAID set. instead i have downloaded ccc and am in the process of setting up the secone 3t external drive as a clone. i will use time machine to back up the internal hard drive only and if possible see if i can clone that as well onto one of the 3t's.
this gives me the peace of mind i sounght and avoids the problem of total corruption that exists with the raid solution i was exploring.
thank you all for making this an enjoyable and informative experience. what a powerful community.
be well

Home Sharing Purchased Applications between 2 Different Ipads

By using the Home Sharing feature I have shared Ipad applications between my Ipad and my wifes's Ipad. The first app was a purchased app and it works fine on both Ipads. However, when I shared other purchased apps they do not load when they are selected on the Ipad. Can someone confirm if you are suppose to be able to share purchased apps and if so why they will not launch when selected on the receiving Ipad?

My wife and I have two ipads and share an itunes account. I beleive that is the "supported" method of doing it. You are purchasing the app, not for use on one device, but on all your devices.
This allows you to upgrade and keep all purchased apps on the next device.
We pick and choose, but can have the same apps across both ipads wihout problems this way.
We have not attempted the Home sharing method as of yet.

Powerpivot 2012 on Excel 2010 - External Data connections not saving passwords, having to re-enter password EVERYTIME I refresh data

Hey Guys,
Using Excel 2010 with latest version of Powerpivot 2012 available 11.1.3129.0
For my SQL Server Data connections in Powerpivot I DO NOT have any issue, when clicking refresh it never asks me to enter a password and uses my Windows AD info.
However, for my plethora of other external data connections (Informix, Oracle, Etc...) that I would like to have fluid use within Powerpivot, big problems.
Lets start with Oracle. Below is a screenshot of my connection tab within Powerpivot.
So as you can see, all the details are entered and Allow Saving Password is selected. Now I will close out of Powerpivot and Excel completely and re-open. I will navigate to the Powerpivot tab
and select Powerpivot Window. And then will select to "Refresh All" and am quickly prompted with the "Data Source Credentials" window to re-enter my data source password, again.
What I have already tried. The above method for starters in which I use a connection string under Table Import Wizard --> Others (OLEDB/ODBC)... I found it the least annoying route, although
still have to re-enter password everytime, which is what I hope this forum can help with.
I also have tried doing a direct Oracle connection in Table Import Wizard but also does not eliminate my #1 problem.
I have also created an ODC file to try and use that with stored credentials within the file, also still asks for password each and everytime.
The same thing happens with my other data connections to Informix and DB2. So any help and/or suggestions anyone has would be great. I also cant upload these powerpivots to our powerpivot gallery
on SharePoint 2010, I have a sneaking suspicion it is due to the version of powerpivot I am currently using.
Thanks

Hi there,
My company is not using Excel 2013, only 2010. So that is what I have to work with. From what I have read this is a huge hole in the Powerpivot 2012 framework and is extremely frustrating. This seems so basic and simple and like something everyone using
this product would use, and yet it still doesnt work.
Great feedback. Connect is the right place for this feedback on 2010 as well. Thanks!

Transferring applications between two Macs in different locations?

What is the easiest way to copy an application between two Macs? I originally installed a graphics program on my old eMac G4, then used the Migration Assistant to transfer it to my new iMac G5. I then reinitialized the old G4 and didn't bother to reinstall the graphics program, but now I would like to have it on this machine as well and I can't find the original install disk for this application. Complicating matters is that the machines are now in two different places, one at home, one at work. This is an expensive program, so I would hate to have to buy another copy and am kicking myself for not being able to find it. Thanks for any help...

If you can't find the original install disk for the program, contact the program vendor. Some may offer you a replacement disk for a nominal fee. And be sure to follow whatever license agreement you have for the purchase of that software. If it can't be installed at both home and at work, and you can't afford another copy of that program, you may want to seek a cheaper alternative.

Download to excel between two given dates

Hi All,
I already implemented Export to Excel funtionality in webdynpro java. Now i have a requirement to download the data to Excel only between two given dates.
I am taking two dates from the user and based on that it should download data into excel file.
Guide me on this or send pseudocode for this.
Regards,
Dhruv

Hi,
If I understand your question correctly,
you are gettting some data from R/3. You need to filter out that data which is in between two given dates , export that data to excel.
If yes, then take one more ValueNode with same structure.
and bind the filtered data to this node.
To filter out model node, use
int size=wdContext.node<outputnode>().size();
Date stDate=wdContext.currentContextElement().get<startDate>();
Date endDate=wdContext.currentContextElement().get<endDate>();
for(int i=0;i<size;i++)
Date objDate=wdContext.node<outputNode>().get<outputNode>ElementAt(i).get<dateAttribute>();
if( (objDate.compareTo(stDate)>=0) && (objDate.compareTo(endDate)<=0) )
// Create element for value Node , set the values (ie. i'th record values) and add to ValueNode.
Long process, but you can use
Now export the ValueNode to excel
Regards
LN

All Dates between two given Dates

Hi,
I need all the dates between two given dates in select-options .
For example the range in select-options is 01/01/2007 - 31/03/2007 .
I need all the dates between the two given dates .
How can i do this .Is there any FM for this ?
Regards,
Zia

use this
CSCP_PARA1_GET_PERIODS
data:begin of daytab occurs 0.
        include structure scscp_period_str.
data:end of daytab.
call function 'CSCP_PARA1_GET_PERIODS'
    exporting
      i_datuv    = r_budat-low
      i_datub    = r_budat-high
      i_timeunit = 'D'
    tables
      et_dates   = daytab.
here u have to put one more logic.
   loop at daytab where datuv in r_budat.
    endloop.
So u will get all the dates

Query to search between two specific dates and time period

Hi,
Need a query to search between two particular dates and time period
Like i want to search table having one date field .
Suppose the date range is '01-JUL-06' and '01-AUG-06' and time frame
is 23:00:00 to 08:00:00
i.e i want to search between dates 01 july to 01 aug and also within the time frame i.e 23:00 to 08:00 hrs only

The general principle is
SELECT * FROM your_table
WHERE some_date BEWTEEN to_date('01-JUL-06') and to_date('01-AUG-06' )+0.99999
AND ( some_date <= trunc(some_date)+8/24
OR some_date >= trunc(some_date)+23/24 )

Sharing aperture library between two computers in same house

How do I go about sharing the same library between two computers in the same house? I would like to take some or all photos around with me on my laptop and be able to have them also at home for use by my family. Will I have trouble with changes and keeping things in sync? Would I locate the library on a portable drive on our home network? Thanks,
Todd

cut and dry ???
are you wanting to constantly move the external around from machine to machine ??? or are you looking for simultaneous access ???
if you had a library on an external and moved it between computers, it could work ... just be careful to always have the external connected before starting aperture, else it will create a new null library for you ...
you could have db issues if you tried to have two people access it at once ... i dont believe that the aperture db could handle multi access at once ... not robust enough ... no locking of records, etc ...

Sharing iPhoto Library between Two User Accounts

Is there any way to fully share a single iPhoto library between two user accounts on one machine (iMac 2.0GHz dual core Intel, 10.5.1, iPhoto '08), without using an external drive (because I don't have one)? By share, I mean each user has full rights and priveledges to the entire library, regardless of who uploaded the pics. Holding down the option key on iPhoto startup does not work because my wife can't access the pics I loaded even though she's pointing to the shared library in a shared folder.

If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc. then:
Quit iPhoto in both accounts
Move the iPhoto Library Folder to an external HD set to ignore permissions. *You could also use a dmg*.
(Some people have had success putting the library in the Users/ Shared folder. If you do this make sure the file permissions are set to allow read/write access to everyone. But that's unlikely to work on 10.5 because of the way that the permissions have changed with the new OS.)
In each account in turn: Hold down the option (or alt) key and launch iPhoto. From the resulting dialogue, select 'Choose Library' and navigate to the new library location. From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

Breaking Links to and External Data Connection using the cubevalue() function

I have spreadsheets that connect to an MSAS cube successfully and pull data in the cells using the CUBEVALUE function.
Is there a way to perform the equivalent of 'breaking links' to the external database so that the spreadsheet can be distibuted to others that will not have the external database connection set up on their computer/excel environment.
I find that if i email a spreadsheet with data retreived using cubevalue functions to someone without the external database connection they do not see the values preserved with the spreadsheet and end up with blank or zero cells, etc.
I have unchecked the box related to 'refresh data when opening file'.
In a perfect world i would like to remove the db connection and be left with pasted values, similar to breaking links to an external workbook but I am not sure if that is possible.
I am desperate to find a way to distribute these spreadsheets and be confident that Excel won't be unsuccessfully trying to refresh a connection that isn't on other peoples computer.
Thanks for any guidance

Maybe you can upload a sample file to a file sharing site and then share the link with us.
As you said you have already unchecked the option 'Refresh data when opening the file' within Connection Properties.
When you send the Excel file to someone without this data connection, they should get the correctly data unless they click the button 'Refresh All'.

Sharing Keynote documents between two macs.

I am Sharing Keynote documents between my two macs via wi-fi, so my question , is there a potential problem of data lost when going back and for from one computer to the other. It is very important that no possible problems may happen for important lectures.....
Thanks

Ok that sounds good, Both computers should have all the fonts, no music at the moment.
I was wondering that I had data lost when transferenig keynote documents using usb memory sticks, lost of pictures, the trick that avoid that was compressing the document before placing it into the usb memory stick.....I undertood that was because of the memory stick format. So going from computer to computer through wifi should be fine...just does recomendations that you were saying. Right ?
