How does Sql server will identify Tomcat server? - sql-server

I have number of applications in Tomcat server and I have sql server 2012 Database. Initially the Database will send the message to application says that database getting changed. Then the application(Tomcat server) fire the query to fetch the data from database.
In my scenario user doesn't have access to application(java, webMathematica, etc.) he has only access to Database to modify data. Initially I start the tomcat server and sql server then I can use JDBC driver to connect application server to sql server.
Now I want know whether database can identify the tomcat server before application server establish the connection to database server to send the message about the data updation.

How do I resolve encryption error connecting to SQL Server from Oracle SQL Developer

My objective is to use the migration tool in SQL Developer to migrate 2 SQL Server databases to Oracle. I am attempting to connect to a SQL Server database at a remote location using Oracle SQL Developer 4.0.
I have installed jtds.1.3.0.jar per instructions, and get the SQL Server and Sybase tabs in the connection properties window.
I have entered the user, pw, hostname, port, and database name. When I try to Retrieve Database, or connect, I get the error message:
Status : Failure -Test failed: I/O Error: DB server closed connection.
The SQL Server DBA tells me her error logs contain the following error message:
Encryption is required to connect to this server but the client library does not support encryption; the connection has been closed. Please upgrade your client library. [CLIENT: (my computer's IP address)] Error: 17835, Severity: 20, State: 1.
When I look at SQL Server documentation about this error message, it talks about certificates and SQL Server Connection Manager. Some relevant information to show that I've covered the basics:
Using the same connection parameters, I am able to connect to the SQL Server database using Toad for SQL Server.
Using the same connection parameters, a DBA set up an Oracle Transparent Gateway, and I can connect to the SQL Server database using the gateway and a database link. (As far as I know, neither of these methods required a certificate to connect.)
Both of these use ODBC; SQL Developer uses jdbc with TCP/IP.
The DBA assures me TCP/IP connection is turned on for the SQL Server databases.
I have gone into the XML file where SQL Developer stores the connection string. It has the form jdbc:jtds:sqlserver://sql-xxx-xxx.mw.nos.xxx.com:1433/my_db, which looks correct. I have tweaked it by adding the instance name, but no difference. The database has a default instance name, anyway, so it shouldn't be necessary.
A co-worker has been able to connect to a local SQL Server database on the same machine where SQL Developer was running (both on his laptop).
As a workaround, I am also pursuing the possibility of installing SQL Server on a local workstation, and copying the databases there for processing, but I don't know if I can get approval. If you know another tool for migrating from SQL Server to Oracle, please also let me know.
Thanks in advance.

500 internal server error in connection string on Azure VM

can someone guide me on this. I have to classic VMs(Application server and Database Server) on Azure. I have a asp.net web application connected to the database server and its working fine. But I needed to install a sql server 2014 on Application server and place a connection string for it in my web application. I have installed sql server 2014 on my application server and restored a database, but as soon as I place a connection string for the newly restored database in my web.config file, I get a 500 internal server error. As soon as I remove the connection string for newly restored database, the application works fine with the rest of the connection string.

Remote connection to SQL in MS access gets calculating state

I have 2 machines which locate in same network. In first is running SQL Server 2014 Express and in second is running a MS Access application which uses the database.
But the problem is if I start MS Access, the first form loads successfully but application is very slow. I have a lot linked tables is MS Access which use database. At the bottom of window has state "Calculating..".
Currently i have allowed remote connection to SQL. I have disabled firewall on the SQL Server machine. I have tested connection via telnet from machine 2 to the SQL Server machine and it was successful.
So what am I missing that my connection via MS Access fails? Can there be some user permissions (but telnet connection was successful)? Is it possible to debug MS Access somehow why the connection is slow?

SQL Server 2008 SSMS connection and http connection string?

I have a SQL Server 2008 on a server which goes out on the internet through a domain name computer.example.com, I want to develop a .net app on my PC and to connect to that database through SSMS - to create tables and so on...
And I still want a connection string which can be accessed from anywhere - I'm thinking at a http url or something like that - which will be consumed by the app.
What do I must to configure on the server so that I can connect via SSMS to the database (from my PC) and how do I get a connection string to that database?
you can use Sql Server Configuration Manager for this work. when you run this application, expand the SQL Server Network Configuration, after that you can see Protocols for sql server 2008. by click on it you can enable or disable TCP/IP.
your connection string can be like this :
connectionString="Database=DBName;Server = Server IP;Integrated Security=false;user id=sa; password=Pass;
