SSIS connect to oracle database

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net

In datasource designer for adding a new data source, I am attempting to connect to an oracle server. I then enter credentials and click 'test connection', and get this error.

Test connection failed because of an error in initializing provider. ORA-12154: TNS:could not resolve the connect indentifier specified.

I am using Oracle 11g as my framework.

The strange thing is if i use enterprise manager using 10.2.1 oracle framework, I cannot see any tables. The only way I can see tables if I go and click on "other  users" and then click on the specific user previous employees have used as their login credentials to generate an SSIS package.

I have already set up the access using enterprise manager, but ssis does not follow? Or something?

Thank you in advance.

SharePoint connect to Oracle Database


We are running a SharePoint 2007 farm and we have staff that want to use a dataview to connect to an Oracle Database as well as a SQL database.  The SLQ connection worked fine. When we try an Oracle Connection using a custom connection string we recieve an error retriving the list of databases.  

Some of the information I have read mentions installing the Oracle Client on the SP Web Front  End servers and others do not.  

Is there a way to connect to an Oracle database without installing the Oracle Cleint on the SP Web Front End servers?

I've read about using BDC, but that seems to involve having the Oracle.dll in the GAC which I believe would require the Oracle client to be installed.

ASP.Net connect to Oracle.


 We have an application which uses  'System.Data.OracleClient'. On the box it was developed we can change the TNSNAMES.ORA entries to connect to different oracle databases. Moving the code to a  Microsoft Server 2008 box it would appear that the application ignores the TNSNAMES.ORA file. It has cached the first Oracle connection and will now work without any TNSNAMES.ORA file. Where is it getting the connection? We have set tns_admin to point at the TNSNAMES.ORA file. We can tnsping the connection OK.

Hi All,

" cannot connect to the configuration database ".

But when I execute following steps, this errors message gone and everything got fine

1. Enable Named Pipe from SQL Server Configuration Manager > Protocols for MSSQLSERVER

2. Restart  SQL Server (MSSQLSERVER) service (Note: This service was already running and status was set to automatic ) and

3. Start SharePoint Configuration Wizard  

Now I need to know why every time I have to restart this service? When I turned on my sharepoint server machines in the moring I have to restart this service ( SQL Server (MSSQLSERVER) otherwise same error message appears (cannot connect to the configuration database). After restarting this service everything gets normal.

Any help in this regard will be greatly appreciated.

connect client certificate to an account in a membership database

Hello I have created a web service that authenticates with username and password, works fine.Basically this one, http://msdn.microsoft.com/en-us/library/ff649647.aspxNow I also want to connect to this web service using client certificates, works finehttp://msdn.microsoft.com/en-us/library/cc948997.aspx But I would like to when authenticated via client certificates, connect that certificate to a user in the membership database.So that I can use Roles.IsUserInRole(...) and such.I thought that, well if I implement a Custom certificate Validatorhttp://msdn.microsoft.com/en-us/library/ms733806.aspxthen I could check for example subject and map that against a created username in the membership database.But in the class X509CertificateValidatorpublic override void Validate(X509Certificate2 certificate)I don't have the same ability as when the user is authenticatedlike  void OnAuthenticateRequest(object source, EventArgs eventArgs)HttpApplication app = (HttpApplication)source;Basically how can I do this app.Context.User = new GenericPrincipal(new GenericIdentity(username, "Membership Provider"),roles);withinpublic override void Validate(X509Certificate2 certificate)and if that is not possible, can this be solved differently?Bottom line, how do I connect a client certificate to a user account in the membership database. Is there a MSDN article

Why can I not connect to SQL Server Database?

Can somebody PLEASE try and assist me with this issue - it's been driving me insane for 2 weeks and I am seriously at the end of my tether now... I'm attempting to use ASP.NET Configuration from the Website Menu of Visual Web Developer 2010 Express. (Note: I have downloaded SQL Server 2008 & SQL Server 2008 R2 with VWD 2010 Express via Web Platform Installer.) I'm selecting 'select a single provider for all site management data' followed by; 'AspNetSQLProvider' but every time I try and click 'test' I get the following error message:   Could not establish a connection to the database.  If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. After the scouring the 'net for literally tens of hours, I've found several forums that I thought would help, such as; * Re-installing SQL Server and copying the .exe file to the desktop to get the SQL Server to be able to be installed properly (which I've done and it seemed to install successfully), BUT even after doing this I keep getting the error as underlined above & * Finding the aspnet_regsql file and installing it via it's wizard I've tried doing the above on both my 32-bit Windows XP laptop AND my 64-bit Windows 7 laptop - b
