Unable to connect to SQL Server 2008 from OBIEE 11G(on 64 bit Linux box)

We are unable to connect to connect to SQL Server 2008 from OBIEE 11G which is on 64 bit Red Hat Enterprise Linux.
Infrastructure: OBIEE 11.1.1.5 64bit, on 64 bit Red Hat Linux Enterprise Linux 5.6 , MS SQL Server 2008 on 64 bit Microsoft Windows Server
Issue Description: Unable to connect to SQL Server 2008 from OBIEE11G RPD
Details: We are unable to connect to SQL Server 2008 from OBIEE which is on a 64 bit Linux box. We created the ODBC connection on Linux box to the SQL server. Whenever we try to import metadata it throws an error that says ‘Connection Failed’.
Here are the steps we followed to setup the ODBC connection on Linux box.
1) We updated the user.sh file with the LD_LIBRARY_PATH and LD_LIBRARY_PATH_64 values that point to $ORACLE_HOME/bifoundation/odbc/lib
This is where we found the driver for SQL server SEmsss23.so.
2) We updated the odbc.ini file with the entry for SQL server with the connection details
SI_SQL_Server_DEV = SQL Server
[SI_SQL_Server_DEV]
Driver=/u001_OAS/Oracle/Middleware/Oracle_BI1/bifoundation/odbc/lib/SEmsss23.so
Description=DataDirect 5.1 SQL Server Wire Protocol
Address=10.230.216.52,54970
AlternateServers=
AnsiNPW=Yes
ConnectionRetryCount=0
ConnectionRetryDelay=3
Database=SVBDW_NEW
LoadBalancing=0
LogonID=SIDatavalidation
Password=~~~Password123
QuoteID=No
ReportCodePageConversionErrors=0
3) We updated the IDENTIFIER_QUOTE_CHAR with single quotes instead of double quotes in the DB features of the RPD
4) We updated the bash_profile file to point the ODBCINI variable to the path where the OBIEE odbc.ini file is present.
Export ODBCINI=/u001_OAS/Oracle/Middleware/instances/instance1/bifoundation/OracleBIApplication/coreapplication/setup/odbc.ini
The error in nqsserver.log file says “[nQSError: 16001] ODBC error state: IM002 code: 0 message: [DataDirect][ODBC lib] Data source name not found and no default driver specified.”

Hi,
Make sure SQL Configuration Manager make sure the TCP/IP enabled. please try below method
Method 1
Re Create a new ODBC & Oracle Bi Server DSN Configuration test it and use it in the connection pools.
define your ODBC data source in your server where the BI Server is installed. Check your DB connections in your physical layer and make they are defined on your BI Server as well.
Method 2:
try using the complete TNS in below format in the datasource name section:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST =DB IP)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ORCL) ) and provide the credentials.
Method 3:
To use the OCI call interface you need to have oracle client DB to be installed so that you can establish a connection using that DB credentials and connect to the remote dB and then import the tables.....this is the rule of thumb.
hope helps you.
Thanks

Sql developer won't connect with SQL server database on cluster

Hello,
I have a microsoft SQL server database on a windows cluster. Name for this cluster is like XXX/YYY
When I try to connect to this database with SQL developer, I get a failure, mentioning:
"Status : Failure -Cannot connect to Miscrosoft SQL Server on XXX/YYY"
As far as I know, I have installed the correct jtds driver (version 1.2.5), since I can connect to sql server databases on single server hosts.
Does anyone know how to connect to databases on windows clusters?

Cannot connect to SQL Server databases

All of a sudden I can't connect to SQL server databases from
my local machine. The databases are on a web server. It just
started happening, and I never had a problem with it before. I
can't connect to them in the coldfusion administrator, and I can't
connect to them using ODBC DSN's either. Has anyone ever run into
this before? I didn't change anything in the cf admin, and I
certainly didn't change any logins or passwords in SQL
Server.

I've been experiencing a similar problem. Everything was fine
but I had to reboot CF 8.01.
After the reboot all the datasources are very slow to respond
and we get lots of errors of the form :
Timed out trying to establish connection
A non-SQL error occurred while requesting a connection from
blah
Timed out trying to establish connection
A non-SQL error occurred while requesting a connection from
blah
Everything is working but very slow on database queries. This
happened a couple of months ago when we last
rebooted and then it went away.
Going to have a look for a new JDBC driver from adobe and see
if that helps ....

Issue with connecting to SQL Server Database in 11g

Hi
We successfully created odbc connection say "Test" to read SQL Server database using odbc admin.The issue we are facing in 11g is, we are unable to import tables using the database connection "Test" in to Admin tool.
In 10g we did not come across this issue. We used the same credentials and process incase of 10g and 11g to read SQL Server database, but we are facing the connection issues incase of 11g.
Please, let us know is there any change need to be done to any config files or is there any way to overcome this issue.
Thanks.

Hi,
What do you mean by 'we are unable to import tables using the database connection'
Do you get an error message or the connection fails or what
Please add the details about the issue in order to help

Hello,
Please run the Discovery Report as shown in the following resource and make sure the Database Engine Services is listed
on the report.
http://blogs.msdn.com/b/petersad/archive/2009/11/13/sql-server-2008-discovery-report.aspx
If the Database Engine Services is listed on the report, please apply SP3 for SQL Server 2008 since SQL Server is not compatible with Windows 8 without that service pack.

Hope this helps.

How can I connect to SQL server database thru local network by using JSP?

I'm currently doing a project by using JSP..And I need to display record from the SQL Server database in our school's local network. May I know how can I do that? How can I write the code so that I can able to access the SQL Server databsase Throught school's network by using JSP? Please tell me step by step how can I do that. I'm using Tomcat 4.1 as Web Server. And I had J2SE and J2EE installed in my computer.

first you have to establish a ODBC DSN on your computer,
that connects to the database...you can do that from your control pannel.
i assume that the TOMCAT server is residing on your computer....(if the webserver is in other computer then you would have to create a System DSN on the data sources ODBC option in the settings>control pannel of that machine)
then you can use that DSN name to connect to the data base from the class file....for further assistance on how to create the class that access the tutorials in sun site.

Linked Server unable to Connect in SQL Server 2012 after Restarting SQL Server Service it works fine. Why?

I have created a Linked Server to Access Database of 64 MB in Size located in Remote System to SQL Server 2012.In Start for Some time it works fine and after it is giving the Error
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LANDLINE_TEST" returned message "Cannot open a database created with a previous version of your application.".
Msg 7303, Level 16, State 1, Procedure Insert_Records_Into_Actual_Calls_History, Line 29
Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LANDLINE_TEST".
Previously I thought it as Permission Issue. By trying some fixes proposed in forums it not fixed. But, after restarting the SQL Server Services without changes to the linked Server it works perfectly. How could i fix it. I don't want restart the SQL Server
Service it leads to Some other process failures.

After all the Errors, When I am restarting the SQL Server its working correctly.
Whats the problem it is clearing itself after restarting of SQL Server. Why ?. I can't find anything regarding this in SQL Server .
The following are the Errors i got connecting to SQl Server.
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LANDLINE_TEST" returned message "Cannot open a database created with a previous version of your application.".

for to fix above error i have followed the instructions in the following link,
http://blogs.msdn.com/b/dataaccesstechnologies/archive/2010/08/19/permissions-needed-to-set-up-linked-server-with-out-of-process-provider.aspx
This also failed to work. I Restarted SQL Server and make the Linked Server Properties Default to my Configuration and it works fine.
Can you suggest me a solution for this issue. Every time i don't want to restart SQL Server Services as it effects other jobs and Processes.
Thank you.

SAP ECC6.0 cannot connect to SQL Server Database after recreating DB server

We had a disaster with our ECC 6.0 Development system a few days ago. The system is called “DEV”. The SQL Server database server got wiped out and we didn’t have a backup. Luckily, we did have a backup of the database. Our system engineers rebuilt the server and our DBA reinstalled SQL Server and restored the database. The database came up fine, but when we try to start SAP, it fails. “R3trans –d” also fails. The database is SQL Server 2008R2 10.50.2769. The OS is Windows Server 2008R2.
We verified that the “devadm” and “SAPServiceDEV” accounts have permissions on the on the server. We set the following Environment Variables for the devadm account on the database server:
DBMS_TYPE = mss
MSSQL_DBNAME = DEV
MSSQL_SCHEMA = dev
MSSQL_SERVER = <database server name>
SAPLOCALHOST = <database server name>
SAPSYSTEMNAME = DEV
We also set the following Registry Key:
HKEY_LOCAL_MACHINE/Software/SAP/DEV
Type:     REG_SZ
Value:   AdmUser
String:   <database server name>\devadm
We didn’t install any kind of SAP software on the database server.
Is there any kind of SAP components we need to install on the database server? Do we need to run the SAP installer on the database server to get everything setup correctly? I looked at another one of our SQL Server database servers and it has SAP Management Console installed and there is a C:\Program Files\SAP\hostcntl folder. I don't know what that is or it has anything to do with SAP being able to connect to the database.
Here is the error message in the R3trans log file:

The target principal name is incorrect

The target principal name is incorrect
Hi Rahul.U,
Are you able to connect to SQL Server successfully from SQL Server Management Studio (SSMS) when enforcing encryption?
According to above error message, it could be caused by the inappropriate server name or incorrect TrustServerCertificate configuration in the connection string from Visual Studio. There are some proposals for you troubleshooting this error.
1. Make sure that you connect to the SQL server using the fully qualified domain name (FQDN).
2. When connecting to a SQL Server instance with a valid certificate, please add the
TrustServerCertificate
parameter and set it to true in the connection string. For more details, please review this
article.
However, if you can successfully connect to SQL Server via SSMS, but still fail to connect to SQL Server from Visual Studio, I would like to recommend you post the question in the .Net Framework forum at
https://social.msdn.microsoft.com/Forums/vstudio/en-US/home?category=netdevelopment . It is appropriate and more experts will assist you.
There are similar articles about error “The target principal name is incorrect” for your reference.

Connecting to sql server database mdf file without installing sql server on client machine?

I am creating a window application that need to use sql server database. I want to install this application to client machine without installing sql server so that my application can still connect to a database i.e mdf file that i will be providing at client
system.
How can i connect to a database(mdf) on client machine through my window application without installing sql server. ? I dont know is it possible or not.
If possible what will be the connection string in that case. Database need not be used in network.

you cant connect and view the internals of mdf file unless it being attached to a sql server instance as a database.
The sql server instance can be installed in any box which is in the same domain and then you can connect from your application to it.

Connection to SQL Server Database

I am working on 4.6C. How can i connect to SQL Sever database ? I am new to this type of concept. Kindly do provide some suggessions !!!

Hi,
In general, if we want to hit database directly, we use..
EXEC.
ENDEXEC.
ex:
DATA: BEGIN OF wa,
        connid   TYPE spfli-connid,
        cityfrom TYPE spfli-cityfrom,
        cityto   TYPE spfli-cityto,
      END OF wa.
DATA c1 TYPE spfli-carrid VALUE 'LH'.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO   :wa
FROM   spfli
WHERE carrid = :c1
ENDEXEC.
FORM loop_output.
WRITE: / wa-connid, wa-cityfrom, wa-cityto.
ENDFORM.

SQL developer connect to SQL server database

Hi Friends,
I have a sql developer 3.2. I download jtds1.2 as a thirty part driver in window. It works and SQL server tab appear on connection window.
But Retrieve database button does not work and not able to enter a sql database name.
Without database name , I got error message as failure 0 test failed:unknow server host name 'CACI1111\SQLEXPRESS'. I use defolt 1433 port.
However, I can open SQL server 2008 express in my local PC.
What do I need to do it?
Thanks

Hello,
my syntax to connect to a non-local SQL Server 2005 Express database is nn.nn.nn.nn/testdb in the hostname field, where nn.nn.nn.nn is the IP address of the other PC and testdb is the name of the database.
Regards
Wolfgang
