Change Connection Strings?

Hi everyone,
When developing a Sinea App, especially in the context of using Office 365 or SharePoint, can we have a method or mechanism to change the data connection without having to remove and re-add the data source.
While developing the app we might choose to connect to lists and libraries in a Dev site and before we publish the app we would want to change the URLs to point to a production site or server.
Regards,
James.

Hi James,
Currently for Office 365, this is the only way to swap out sources in the manner you described. The reason is when you add the data source and successfully sign in, we grab key details such as what tenant you are on? What services are available to you? And
bake those into the connector.
Therefore, when switching between development and production sites, this information will change and as such we need to query the server for these key details again, and add the connector configured appropriately for this new server. As long as the
names are the same, most of the rules should be fine, but we definitely understand that there will be some friction.
As we evolve the product and the oppourtunity arises, this is definitely something we'll consider. Many thanks for the feedback.

Hi,
I have copied a number of SSID packages from a live server to my test server and am trying to get them up and running but I have a problem with the connection. The only thing that is different is the server name. I decided to keep the same connection in the connection manager as it is referenced in a dtsConfig file. I changed the dtsConfig file to reference the new servername [Data Source= new test server name]. I also check my paths and they are pointing to the correct config locations etc.
I found this post which was similar to my problem but I still get problems with the connection
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1319961&SiteID=1
I updated the connection by changing the server name in the actual connection. I did this from the data flow tab in the Connection Managers sections (MS Visual Studio). Right clicked - Edit - changed the name of the server name to my test server and selected the database. Test connection was fine, and saved this.
Once I saved this, the connection string changed to my current test server in the properties of the connection. However when I run the package I get the following error:
Error: 0xC0202009 at ReportsImport, Connection manager "myconnectionstring": SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.

So even if I change the existing connection properties and save and Build my package again, my connection properties (connectionstring, servername etc) all revert back to its original data source when I re-open the package. Simply it does not seem to be saving the connection properties i put in.
What am I doing wrong or how can I change the existing connection manager to look at the new server. The database is the same and I have full admin privilege on the server.
I don't want to recreate my packages as there are alot and they are not simple.
After changing the connection properties, saving and reloading I get a connection error. But this is because it is not retaining the new connection manger setting i entered.
Incidentally - I created a new SSID to perform a simple connection and write to the the server and it was OK so there is no problem with actually seeing the my test server.
Thanks in advance

Yes, the package is in visual studio and I have executed it. There are no errors but in the output i have the error message about my connection. My dtsConfig file is added to the project in the 'Package Configuration Organizer' and path and files are correct. This is the output error:
Error: 0xC020801C at xx import from file, xxReportsImport [79]: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "myconnectionname" failed with error code 0xC0202009.

I will try and run it using dtexec.exe. if I have two config files do i use
dtsexec.exe /f <packagename> /conf <configfile> /conf <secondconfigfile>

Changing connection string host from localhost to IP address produces error

Hi all,
First of all, thanks in advance for your help. Second, I know next to nothing about Oracle database administration, so please be patient, but I want to understand things, rather than just running down the Google rabbit hole with guess-and-check until things happen to work and I don't know why.
I've got a connection string that I'm using to connect to a local Oracle database I'm using for testing. I have the 11g installed and the 11.1.0.7 64-bit client (as my application is a 64-bit application) installed, both locally on my development machine. I've got a connection working using the following connection string:
Data Source=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = mywindowslogin.path.to.me)));User Id=********;Password=********;However, when I change "localhost" to my IP address, my computer name, or anything else, I get "ORA-12541: TNS:no listener".
The tnsnames.ora in my database home is as follows - it was set up for me automatically when I installed the database. mywindowslogin.path.to.me doesn't point to anywhere, which I assume is correct, but my computer is on the path.to.me domain.
LISTENER_MYWINDOWSLOGIN =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
MYWINDOWSLOGIN =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = mywindowslogin.path.to.me)
)How can I resolve this issue?
Edited by: Don on Jul 14, 2010 8:31 AM

Does setting the environment variable affect all installations? Only two of my four Oracle Homes have a tnsnames.ora file, or event a NETWORK/ADMIN location, so I'm not sure where to put tnsnames.ora in those Homes. I copied the tnsnames.ora for my database to the one other Home that had a NETWORK/ADMIN location, but I'm still getting "ORA-12541: TNS:no listener" if I don't use "localhost" as the host.
Thanks!

How to change connection string for a form created with b1de

Hi all
i've created a form using the Code Generator tool ob B1DE
My question is how can i set the connection string to a different server and database. doing so after the creation wizard has finished?

Hi,
Why do you need to change the connection string? What are you calling "connection string for a form"???
The only connection string I now about is the one used to connect to the UI API... and this one is fixed for all apps in debug mode and given as parameter when your addon is registered in B1.
The connection string is filled in the code of your generated addon.
Please go to the main class of your addon, in the main method you have the following code where the connection string is filled either with the command line parameters (release mode) or with the fixed value given by SAP. This code doesn't need to be changed...
        public static void Main()
            int retCode = 0;
            string connStr = "";
            bool diRequired = true;
            // CHANGE ADDON IDENTIFIER BEFORE RELEASING TO CUSTOMER (Solution Identifier)
            string addOnIdentifierStr = "";
            if ((System.Environment.GetCommandLineArgs().Length == 1)) {
                connStr = B1Connections.connStr;
            else {
                connStr = System.Environment.GetCommandLineArgs().GetValue(1).ToString();
            try {
                // INIT CONNECTIONS
                retCode = B1Connections.Init(connStr, addOnIdentifierStr, diRequired);

Trinidad.

Changing Connection String dynamically at runtime

I am using the Crystal Report Viewer control in in a Visuall Studio 2008 C# project. The reports are created inside of Visual Studio 2008, and will be running against an InterSystems Cache database. I have to use an ODBC (RDO) connection and use a connection string.
I have seen many examples of how to update the connection string at runtime if it is SQL server (or some flavor thereof), but nothing for an ODBC (RDO) connection to a NON-MSSQL database.
The problem when I update the connection string for each of the tables in the report, the report will either not run and display a window -- tiled 'Datbase Login' -- that has the Server, Database, Username, and Password fields on the window, OR, it will run but not against the database that was specified at runtime (it uses the connection stored in the report).
Code Sample #1 (This is using the connection string, and will cause a the "Database Login" window to be displayed - the first scenario from above)
rd = new ReportDocument();
// Load the report
rd.Load(fileName, OpenReportMethod.OpenReportByDefault);
rd.Refresh();
// Create the connection object
ConnectionInfo connectionInfo = CreateConnection(Server, Port, ServerNamespace, Username, Password);
// Set the connection info on each table in the report

I have also tried setting connectionInfo.ServerName equal to just the real server name, but that didn't work either.
After the above operations are performed, I simply assign the returned ReportDocument object to the Crystal Viewer control. If I don't call the above functions, and just set the ReportDocument source (using whatever connection string was embedded in the report originally), the report runs as expected. Only when I attempt to update the connection string, the report will not execute. Please advise. Thanks!

SQL 2000 ODBC CONNECTION STRING FOR SQL 2008

i have vb 6 application. Database is SQL server 2000.
my connection string is (using odbc driver),
        .ConnectionString = "Driver={SQL Server};SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
Now i have tried this application with SQL server express 2008 R2
Can i still keep the old connection string? will there be any problem in future?
(if i have to change then have to change at so many places.....)
I can run application without any problem for now (not changed connection string to new one)
otherwise i have to use ODBC or OLEDB which are,
        .ConnectionString = "Driver={SQL Server Native Client 10.0};SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
or
        .ConnectionString = "Provider=SQLNCLI10;SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
if i have to change to new connection string Which one is better to use odbc or oledb.

personally I favor ODBC as it is easy to use sometime. Additionally you can check the link below:

Can't change the connection string of SSIS package with derived columns?

We upgraded SQL server 2008 to 2012, copied and converted all SSIS packages from Visual Studio 2008 to 2010. When I opened a package in VS 2010 and tried to change the connection string, in the local connection managers, if the data source is another
SSIS package B(.dtsx file) with derived columns, I can't change the connection string of package B. When I opened the file connection manager editor for package B and tried to locate a dtsx file in another location, saved the change, reopened the project.
Package B still pointed to previous file. Other packages without derived columns work fine. Any thoughts?

We are using the package deployment model and refer to other packages in the same project. If
we changed the path of package B (with derived columns) to "D:\Visual Studio 2010\xxxx", and refer it in package A, in the A's connection manager, the connection string of package B is still its previous location "D:\Visual
Studio 2008\xxxx". When we ran the package A in the SQL server agent, the data source is still
"D:\Visual
Studio 2008\xxxx", so how can I change it to "D:\Visual
Studio 2010\xxxx"? Why has the package C (without derived columns) no such problem? thanks.

Changing the server name on package connection string.

I have a connection string in a package which is a local connection string and not in project connection manager and isn't parameterize as well. Now I need to change a server name of the connection property without using editor. Can I do that and how ?
Moyz Khan

I agree about using configuration for connection string but unfortunately this is an inherited project/packages . And my task it to make these run as currently I don't have luxury to modified it.
So I was able to change most of the connection string with below update
update[SSISDB].[internal].[execution_parameter_values]
setparameter_value=replace(cast(parameter_valueasvarchar),'OldServer',NEwServer)
update[SSISDB].[internal].[object_parameters]
set[design_default_value]=
replace(
cast([design_default_value]asvarchar(1000)),'OldServer','NEwServer')
Now the only one its complaining is the Project connection string . If I know where to look and update that I might be able to run these packages .

Change local connection string on remote server

Hello,
I have searched every post and tried every connection string there but can't figure out how to connect to my database on my remote server. I am using Visual Developer 2005 Express Edition in C# and uploading it to a Windows server running asp.net 2.0. The domain has not resolved yet.
I am so new to this and have followed many tutorials step by step but none of them address this issue. They just show how to upload it to the server.
Do I need to use the SQL server provided by my host or can the database stay in the App_Data folder?
My local connection string works locally:
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
When I uploaded to my server I changed \SQLEXPRESS to (local) as advised in the forum.
<add name="ConnectionString" connectionString="Data Source=(local);AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
When I debug a page I get the <customErrors mode="Off"/>
error message even thought I have already set it in my remote web.config file which may be causing problems itself:
<configuration>
<appSettings/>
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=(local);AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
<system.web>
<customErrors mode="Off" />
<compilation debug="false" />
<authentication mode="Windows" />
</system.web>
</configuration>
Thanks for any help you can offer. I wish I could find someone to hire to do this part for me or teach me how over the phone. Any suggestions?

Is this still an issue?
Thanks!

How to achieve synchronization after DCP connection string changed via sdk

Hi guys,
i have modified the DCP connection string using method: metaDataProperties.setProperty("SI_METADATA_BVCONN_ATTRIBUTES", new string here) via BOE SDK for java, and then
checked it through Query Builder
:select * from CI_APPOBJECTS where SI_GUID=' DC(DataConnection) GUID' ,
it appears ok, the DCP connection string has been changed.
but the problem is :
when i logon to the infoview or cmc , i find that the information of DCP parameter is still the former one.
(in most cases , it display the old, former con-info, but it also display the correct new data several times )
And if i restart the machine , it will be work ok , infoview will get the latest DCP parameters information.
(related service restarting is of no effect)
how to refresh the latest boe managed information?
Thanks.
Regards,
Jinling.

Not quite what I meant - I was suggesting you load the entity immediately after reading it from PU_B, or anytime before associating it into PU_A, so before the merge. What you have not shown though is any code on how you are obtaining IntegrationDepartment and integrating it into PU_A, or what you mean by it is returning a refreshed version of Topic. This problem could also be the result of how your provider works internally - this is a TopLink/EclipseLink forum post so I cannot really tell you why you get the exception other than it would be expected to work as described with EclipseLink as the JPA provider.
So the best suggestions I can come up with are prefetch your entity, try posting in a hibernate forum, or try using EclipseLink/TopLink so someone here might be better able to help you with any problems that arise.

SSRS 2005 change datasource / Connection String

Hi All
I need to change the some shared data source on ssrs 2005 for the migration of some dbs.
Can I do it on tsql, I need to update the datasource / Connection String only for the reports that uses it.
How to change it on table : [ReportServer].[dbo].[DataSource] table. ?
Thanks a lot in advance.

It is not recommended to update records directly in Catalog table.
You can try
programmatic way to update that.
SSRS is webservice so you have to use something like below.
https://<<Report Server Name>>/ReportServer/ReportService2005.asmx
Make sure you do BACKUP database before doing any changes.

Trying to change the Release/Debug connection string (ORACLE) of a VS13 Lightswitch project. Getting ORA-00942 error...

Hello,
i try to change the connection string of a Lightswitch 2013 project. I have a database for developers and a 'productive' database for releases. Both are similar (table names, entries etc..) and they are from ORACLE. First i attached the developer database
as an external source. Everything works fine. Now I'm trying to change the connection string whether my application is in a release state or in a developer state.
I found a hint in the following question to solve that issue: Question
from a LS-User
It is possible to change the connection string during the runtime. I tried it out and added to my DataBaseService.lsml.cs:
partial void DataBase_InitializingConnection(DatabaseConnectionState state)
state.ConnectionString = "DATA SOURCE=DB.productive;PASSWORD=password;PERSIST SECURITY INFO=True;USER ID=USER_PROD";
Well, Lightswitch is using the new connection. But when i run the application, i am getting the error "ORA-00942: table or view does not exist". The views and tables definitely exist. The two schemas are the same. So what am i doing wrong?
Regards from Munich

HI Munich,
Welcome to Lightswitch forum.
According to your description above, you want to connect to external datasource in Lightswitch application.
Oracle is not a supported data source for LightSwitch, it's recommended to use SQL Server database.
If you want to change the connection string, you can update the connection string for a data source using the data source wizard. For example in VS2013:
Please let me know if there is anything that I can do to help.

Change database connection string

Hi, does anybody know if it possible (and eventyally how) to change the DB connection string of the farm (both WF and SB). I do not need to change DB or server, just a parameter of the connection string.
Thanks,
Simone

The Connection string will be persisted in the config database as well as in the registry. I don't think there are any APIs to change it.
