Background: I am really new. Informatica Developer for PowerCenter Express Version: 9.6.1 HotFix 2
I am trying to connect to a sql server 2012 database. I created this connection
, basically just changed the server, database in connection string of meatadata access and data access. I have tested I can use the user name password to access the sql server in sql server management studio. And when I click test it reports successful.
But when I create a mapping and a physical object (read) based on that connection, when I try data view on that object, it reports this error:
[LDTMCMN_0029] message [com.informatica.sdk.dtm.ExecutionException: [LDTM_0072] RR_4036 Error connecting to database [
Microsoft SQL Server Native Client 11.0: Login timeout expired

Database driver error...
Function Name : Connect
Database Error: Failed to connect to database using user [bcsgetl] and connection string [192.168.100.88:1433].].]
One thing to note, when I created that physical object, I used that connection and I was able to select a table, which proves the connection is successful.
As from the error message "Connection string is not valid".
For a Native SQL Server connection work without provide it
Your can try a connection with the ODBC protocol, but instead as for the PowerCenter, where it need to be created a ODBC 64 bit connection on the Windows Server 2012, for the developer and PowerCenter Express, instead I found that it need still an ODBC but from the local machine.
Follow this steps:
-Launch the ODBC Administrator using the odbcad32.exe file located in the
C:\Windows\SysWOW64 directory.
-Create a new ODBC SQL data source under user and make sure do not use space in the name.
-Restart the Developer Client.
-Create in the Developer Client a ODBC connection with your parameters.
Please make sure to use as "Connection String" the same you used for the ODBC source on your local machine.
So if you called it "SQL_Local" that is your Connection String

I'm trying to use POCO to connect to my database.
Whenever I try to connect, I get this error:
Failed to load provider "System.Data.SqlClient".
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
NOTE: it's a local database, and remote access is enabled, TCP/IP is enabled, and the SQL Server service is running.
I'm using .NET Core 7
Can anyone tell me how to solve this?
Thank you all
I am trying to connect the oracle database using universal data link(UDL) with the provider as "Oracle provider for OLEDB"
The test connection fails with the below error
Test connection failed because of an error in initializing provider. ORA-12170: TNS:Connect timeout occurred
I am able to connect to the oracle database using SQLPLUS and Oracle SQL Developer from the same machine.
Please suggest the possible root cause of the issue.
I am getting the following error while using linked server in sql to connect and external oracle db
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "xxxx".
OLE DB provider "OraOLEDB.Oracle" for linked server "xxx" returned message "ORA-12638: Credential retrieval failed".
I am having this issue around 4 out 5 times. So it works only sometimes.
In my case, the test and live oracle DB(external) is on the same physical server with different SID/db instance.
The test connection using OraOLEDB works consistently, it's the live linked server that's the problem.
Also to take out the network from equation I tried connecting oracle live from our test environment and oracle test from our live. Connection to oracle test works fine irrespective and live doesn't.
I can connect to the application fronting the External Oracle DB fine using the live login credentials that are used for the live linked server. So that to me takes the login account out of the question.
Question 1:- Is there any other way to connect to external Oracle DB from either via sql or C#?
I used openrowset as below and get an error:
SELECT *
FROM OPENROWSET('OraOLEDB.Oracle', 'Data Source=external_Oracle_serverIP;Initial Catalog=bbinstance;User id=xxx; Password=xx;',
'SELECT * FROM dbname')
I get the following error
OLE DB provider "OraOLEDB.Oracle" for linked server "(null)" returned message "ORA-12560: TNS:protocol adapter error". Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "(null)".
Question 2: What am I doing wrong above?
When I've encountered this issue, it's because of the following line in sqlnet.ora:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
This causes Oracle to attempt to use Windows Native Authentication Services.
If Oracle cannot authenticate via this method, you'll get the 12638 error. To troubleshoot, change this line to
SQLNET.AUTHENTICATION_SERVICES= (NONE)
and repeat your test to the live database.
Oracle 12c & Above:
Sometimes, there are chances that 2 Oracle Pluggable DB services running under different root databases can run with same listener creating this chaos. Check and stop (if not Prod) unwanted PDB and try connecting to the required DB.
I'm moving a VB.NET 2010 app from a 32bit 2003 server to a 64bit 2008 server that connects to an Oracle 11g database, and am getting the following error message when executing it.
DefaultSource Error 2
ERROR [08004] [Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified
ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed
Here's some things I've done.
Added the TNS_ADMIN environment variable to the server.
Had server management install the 64bit "Oracle driver Oracle in OraClient11g_home1". They also uninstalled the 32bit "Microsoft ODBC for Oracle" driver.
Verified I can connect to the server using SQLPlus
Updated my connection string as I use to use the 32bit "Microsoft ODBC for Oracle"
Added the database to the ODBC System DNS, and verified the connection worked.
Here's my connection string from my config file under the node.
<add name="SCHEMA_NAME"
connectionString="Driver={Oracle in OraClient11g_home1};Dbq=DATABASE_NAME;uid=USER;pwd=PASSWORD;"/>
Any suggestions to what I can try, or what needs to be changed to get this working on the new server?
I fixed the problem by changing the way I connect to oracle. I'm using the Oracle.DataAccess reference, removing the driver reference in the connection string, and rebuilding the connection using OracleConnection and oracleCommand.
been trying to configure an ADO.NET connection for my Visual Studio application but I am running into issues and having no luck at all troubleshooting them. The major error that I run into is:
A network-related or instance-specific error occurred while establishing a connection to SQL server. The server was not found or not accessible. Verify the instance name is correct and that SQL server is configured to allow remote connections (Error 40: Could not open connection to the SQL server)
The steps I undertook to troubleshoot this are:
1. Open up Sql server configuration manager and under the SQL Server Network Configuration, Protocols for MSSQLSERVER,SQLExpress, SQL server 2008 connection string data source I enable each of the protocol names (Shared memory, Named pipes,TCP/IP,VIA)
As instructed I stop the SQL server services first under the SQL server services nodes.
Now I click start, MSSQL server service starts but both SQL Server 2008 and SQLEXPRESS agents do not. Stating the following:
The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details
This might just be the problem as when I attempt to create the connection string , the server name specified is MYWORLD/SQL SERVER 2008. Since the SQL server 2008 agent service refuses to start, the connection fails, leading to the first error message.
Does anybody have any leads on this and can let me know the necessary steps to mitigate this.
The SQL Browser service must be running to connect to a named instance.
Use SQL Servr Configuration Manager under Configuration Tools under Microsot SQL Server 2008 to assign the logon accounts for each service you want to run. Do NOT use any other method to assign user accounts because the correct rights will not be enabled.
