Error in establishing connection to SQL server

Hi All,
I am working on SQL->Sender JDBC->XI----->Reciever RFC -
> SAP scenario.
I have completed the configuration of the scenario.
The sql server is mySQL 2000.
Hence, in the sender JDBC adapter, i have given the following details.
JDBC Driver: com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection: jdbc:microsoft:sqlserver://<HOST>:<PORT>[;DatabaseName=<DB>]
my connection: jdbc:microsoft:sqlserver://172.20.20.76:1143[;DatabaseName=SEPG_NEWDB]
In Runtime Workbench->Component Monitoring>Adapter Engine--->Communication Channel Monitoring..
I am facing error as follows.....
Error during database connection to the database URL 'jdbc:microsoft:sqlserver://172.20.20.76:1433[;DatabaseName=SEPG_NEWDB]' using the JDBC driver 'com.microsoft.jdbc.sqlserver.SQLServerDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:microsoft:sqlserver://172.20.20.76:1433[;DatabaseName=SEPG_NEWDB]': SAPClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver'
What might be the reason behind this error....??????
Kindly help me.....
Regards
Pavan

what i meant was have you deployed the proper jar file(driver file) in the .sda file in using SDM......your driver parameter is fine just check this below
download the jdbc driver from url http://download.softagency.net/MySQL/Downloads/Connector-J/
(mysql-connector-java-3.1.14-bin.jar if you are using mysql 4.0)
the your parameter in Dapter
DBC driver: com.microsoft.jdbc.sqlserver.sqlserverdriver
connection: jdbc:microsoft:sqlserver://ip:port;databasename
also check this
tther option is download JDBC Driver from Microsoft Website
http://www.microsoft.com/downloads/details.aspx?FamilyID=6D483869-816A-44CB-9787-A866235EFC7C&displaylang=en
and deploy the JDBC driver using SDM.

Failed to Establish connection with SQL Server

hi I have configured odbc settings and when i connect the sql from essbase i got the error :Failed to Establish connection with SQL Server .please hepl me on this
and please give me step by step process for how to resolve thi issue.and give me detail step by step from starting onwards.
appreciate your Help,
Thank u
Subbu.

Steps:
1. Test database connection from Essbase server through SQL Command. This gives you whether you are able to connect to Database from Essbase server.
2. Create ODBC Connection: System DSN>Add>Select correct driver (Oracle in ...) >give Datasource (any name), Description (Any), TNS Service Name (user SID name), User name (Database user name)
3. Test Connection. if successful, you can use this ODBC to get the data.
4. Open rules file, go to FILE>Open SQL
5. Provide Essbase server, Application, Database names
6. Select SQL Data Source from the list (ODBC defined in step2)
7. Enter tested SQL Query(which is tested at SQL command or "sysdate from dual" ) in select box. NOTE: Remove select word from query. You can ignore from and where clauses, all you can include in select block.
8.Click OK/Reteive data

OLE DB or ODBC error: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied

Hi,
I have one client and one server. In both hosts I created an OS-user named User1.
The user have been given various role under the prefix SQLServer2005.
The default instance of SQL Server and instance (background-process) of
Analysis Service are also run under User1.
I connected via Management Studio to Analysis Service directly in the
server. I set the permission to access Analysis Service to Everyone.
This means everyone should be able to use Analysis Service. I have set
ODBC data source to the server. Testing was successful.
I created a project to create a cube. The tables are fairly small (total 300 MB, biggest one 290).
On project setting (created at client) I set the server host as
deployment target. I managed to deploy project when all I have are Data
Source and Data Source Views.
But on deployment I always failed. The errors remain the same, begins with
OLE DB error: OLE DB or ODBC error: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.; 08001.
I have tried 4 combinations of Impersonation :
(A) Use a specific username and password
* in which I supply User1 and the password of User1
(B) Use the service account
(C) Use the credentials of the current user
(D) Default
Why is this? The server does certainly exist. I think the error message is wrong.
I have seen 3 posting that seems related. One of them say the solution is giving the right impersonation, but gave no detail. About the privilege, User1 are granted the role of
SQLServer2005MSOLAP. What is the solution?
Thank you,

I just had this problem and solved it by creating an alias in SQL Server Configuration Manager, as below:
Scenario: My SQL server is accessible from the internet under my.domain.com, and from itself at ServerName. But the local network can't see itself through the router at my.domain.com, so the deployed project is unable to process the cube, since that would
require Analysis Services to be able to see the SQL Server at my.domain.com, which it can't do.
So I changed the server in my project from my.domain.com to ServerName, and I created a local alias to ServerName in SQL Server Configuration Manager, under SQL Native Client 11.0 Configuration, Aliases. In my case, I pointed it to localhost port 1333, and
used SSH -L 1333:my.domain.com:1433, but I could have pointed the alias directly to the server, just as well. (Verifying... yes, that worked too, so you can forget SSH if you have no interest in it.)

1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

Cannot establish connection with SQL server from SQL developer

Hi, I recently downloaded SQL Developer version 3.0.04 and am trying to establish a connection to a remote SQL server. The database was created on this server by someone who is no longer working on the project. I have been given the username, password and server name. Is there another piece of information I am missing? I keep receiving the error:
Status: Failure-Test failed: IO Error: The Network Adapter could not establish the connection.

Check out the SQL Server network configuration. When instances are used the port on which the SQL Server is listening on might be different. Use the networking utility from the SQL Server and check out the SQL Server network details.

Hi dude!
Checking the dbsl_w<NN> as it is explained in point 3 of the 'Troubleshooting' section of [SAP note 738371|https://service.sap.com/sap/support/notes/738371] would help a lot to know the reason of the failure.

BI Publisher can not establish connection to SQL Server.

Hi,
We are trying to create a connection from BI Publisher to SQL Server database. However, we are getting a message 'Could not establish connection'. We tried to google to find a solution.
We are not sure what the problem is. We can ping to the SQL Server machine from the BI Application Server.
Apparently it looks like the required JDBC Driver files are missing. We are using OBIEE version 11.1.1.3.0 and 11.1.1.6.0. How do we know whether or not we have the correct JDBC driver file? And also, where we should copy the JDBC driver/jar files to.
Any help will be highly appreciated.
Thanks and regards,
Manoj.

Hi Parham,
Thanks for your reply.
The "Use System User" check box is disabled. The default value for 'Database Driver Class' is "hyperion.jdbc.sqlserver.SQLServerDriver". Should that be correct?
We have SQL Server 2012 but 'Driver Type' shows only two versions of SQL Server - 2005 and 2008.
Folder 'C:\oracle\product\11.1.1\obiee11\wlserver_10.3\server\lib' contains three .dll files: "64sqljdbc.dll", "x64sqljdbc.dll" and "sqljdbc.dll". And "wlsqlserver.jar" is present too in the same folder.
Any pointers, please?
Thanks,
Manoj.

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.

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.

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

I using SQL 2000 on Server 2012 in named instance. when i connect locally, it's ok, but when try to connect from network it generates error [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

Hi Sayed Abdul Latif,
As other post, SQL Server 2000 was out of support since April,2013. You can try to install SQL Server 2005 or later version. In addition, since the issue regards SQL Server Data Access. I will help you post the question in the related forums. It is appropriate
and more experts will assist you.
According to your description, you can only connect to SQL Server locally, I recommend you check if the TCP/IP and Named Pipes are enabled in SQL Server Configuration Manager. And the SQL Server is set to allow remote connection. Then restart the SQL Service
and check if you can connect to SQL Server remotely.
Additionally, we also need to verify if the SQL Server named instance is in a cluster, and connect to it by using the "servername\instancename" syntax, then you receive the above error message. If yes, you have to hardcode the TCP port or the Named Pipe
of the SQL Server named instance. For more information, you can review the following article.http://support.microsoft.com/kb/888228/en-us

I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

Azure Webjobs with EF DB - A network-related or instance-specific error occurred while establishing a connection to SQL Server

Hi,
I have been trying to get a very simple WebJob developed and deployed onto Azure with little to no luck. I have a MVC Website which has a common project which handles my Data Access Layer with Entity Framework. I have created a WebJob project
using Visual Studio and added the following lines of code to the Manual Trigger Function
[NoAutomaticTrigger]
public static void ManualTrigger(TextWriter log, int value, [Queue("queue")] out string message)
RitualDBEntities db = new RitualDBEntities();
log.WriteLine("Function is invoked with value={0}", value);
List<Location> locations = db.Locations.ToList();
string msg = string.Empty;
foreach (Location location in locations)
msg += location.Name;
message = msg;
log.WriteLine("Following message will be written on the Queue={0}", message);
In my app.config of my WebJob i have the following connection strings:
<add name="RitualDBEntities" connectionString="metadata=res://*/RitualDBEntities.csdl|res://*/RitualDBEntities.ssdl|res://*/RitualDBEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=ritual-pc\sqlexpress;initial catalog=RitualDB;integrated security=True;persist security info=False;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="RitualContext" connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=RitualDB;Data Source=ritual-pc\sqlexpress" providerName="System.Data.SqlClient" />
<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****"/>
<add name="AzureWebJobsStorage" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****" />
When i test locally (F5 Debugging) the webjob runs successfully and does the loop of the objects returned from the database. When i deploy this Azure the WebJob fails with the following error:

If i remove any of my database code and use just the basic Stub code my webjob will run successfully so i know that my connection strings (outside of the DB ones) are correct. My MVC web application also runs perfectly using the same connection strings
in Azure so i also know that they have also been configured.
I am now lost and need some guidance, so if someone is able to assist me that would be much appreciated.
Thanks
Ritual.

Can you try to log the connection string you are using in both cases to make sure they are the same?
Also can you share your site name, either directly or indirectly?
This will help us investigate.
Thanks,
Amit

A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Dear all,
I know that this topic may be a bit old school; but it really make me mad as I tried all solutions i found and it still cant be resolved....please give a hand...
The situation is like this,my company divided different platform as a status of project, like DEV, SIT and UAT. I got a project that require me to upgrade an vs2003 project to vs2005. I upgraded it completely and
successfully, it works fine in development and UAT platform; EXCEPT, the SIT platform.
The situation is very strange that, once I move the source to SIT, it return the following error:
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
but it never happen in either DEV or UAT platform and even do I copy the workable web.config from DEV or UAT platform to SIT, the error still here and unable to resolve it.
I search a lot in the internet by Google, but solution suggested are not suitable or fail in my case. Most answer suggest that "enable remote control", "check fire wall", "check server" etc......But as I can connect well the
DBServer in DEV and UAT properly, I dont think those are the cause(but still, I check them all, and all are enabled properly, except my firewall setting is OFF, so adding port is ignored).
After all the searching and testing, I believed and have reason to believe that, the cause is inside my web.config:
<appSettings>


<clear/>
<add key="Environment" value="UAT v1.31"/>
<add key="DBServer" value="DB_UAT"/>
<add key="cnBPSS.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTBPSSConn.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=False;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTDSBDBConn.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="cnDSBDB.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="Timer1.Enabled" value="True"/>
<add key="Timer1.AutoReset" value="True"/>
<add key="cnbpss.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
<add key="cnbpss1.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
</appSettings>
</configuration>
I know such kind of setting is old school; But due to this program runs for few years from tons of ppl...I dont dare to modify it unless I am very sure they are the cause.....
May I ask if anyone cna give me some advice and help in this issue please? I already tried for weeks and turning mad....Please I really need some help...
Many thanks.
Ksun Chan
