The answer is: it depends.
It depends on the programming language you are using and partially on the database you are using.
Most of the databases are services running on a web service. We can communicate with them using a special protocol, while we know the address and the port of the server where it runs. There are also databases stored in files, where we specify the target file.
Most of the programming lanugages and frameworks provide a "Connector" for databases, which allows us to communicate with the database. Of course you need to check if your programming language has a driver for the database type you want to connect to. Some frameworks or programming languaes also offer a higher level control structures called object-relational mapping, where the user can easily read or write some objects defined in the project.



It is simple, just follow the steps

When you create a database connection, it is appended to the list in the Database Manager dialog box.

To add a database connection:

1. In Workspace, select Tools, then Database Connection Manager.

2. Click New.

3. In Database Connection Name, enter a name for the database connection.

4. Select a data source type of Essbase.

5. In Server, add the Essbase Server Name and Port Number.

6. Re-enter the User ID and Password.

7.To add application and database names, click the magnifying glass, and make your selections.

8. Finally , click OK .

The database connection profile is appended to the list in Database Connection Manager dialog box.


I can not set a database connection

You are unable to set your database connection.

Oracle connection error

Possible causes could be
-Bad configuration of TNSNAMES.ORA.
-No repository is located where is the service name identifier

The solution presented are:
-First Check TNSNAMES.ORA file of the database or the client you are using and check the settings, the most important are the HOST, SID and the ALIAS of the database, see if they match data from the computer that owns the database (server). The TNSNAMES is usually in a folder called Network or on NET80 in the case of some customers ORACLE.

A typical TNSNAMES of the database is as follows:
(ADDRESS = (PROTOCOL = TCP)(HOST = Server Name) (PORT = 1521))
(SERVICE_NAME = Service Name)

-Check that the service name matches the name that Windows provides, in the case of Oracle Database XE is always the XE service, other service facilities will be named as he was appointed at the time of creating the basis data.

Oracle connection error

When you have just installed a database or client Oracle on a computer and want to connect with the parameters that have defined, it generates the error message: ORA-12154: TNS: Could not resolve the connect identifier specified.

JBoss and SSL configuration

This challenge is quite old, in the meantime a nice and elaborated solution for this problem has been described here

This is not a solution in the sense of tech screen - so don't rate it


Connection to a network server via windows explorer network drives

CodeBeamer offers a webfolder that can be accessed with the help of the Windows Explorer. Connection to a server that’s located somewhere in the web can be done by using the wizard of connecting to network drives. Use “Extras” – “Connect to network drive”, which opens a wizard to connecting to computer in the local network. On the bottom of this wizard there are some more options. Here you can choose to “connect to a network server”, which starts a new wizard. Just go through the wizard, enter the URL of the codebeamer-server which is Then just save the connection, it appears under your “Networks” in the Windows Explorer and offers all of the server content in the convenient environment of the Explorer.

Windows SBS2003 Drops Internet Connection

I administrate a small (1 server, <10 clients) network where I deployed a Windows Small Business Server 2003 Standard as domain controller, DNS / Exchange / WSUS / PostgreSQL / ... server, and default gateway (2 NICs). However the internet connection is occasionally dropped. There is no specific behaviour identifyable for it to occur - neither some specific action nor time (sometimes it happens after a few days, sometimes multiple times a day). After the connection has been dropped, someone must log into the server, disable the offending NIC, enable it again and everything is fine until the next failure. Alternatively one could restart the server, but it has the same effect and also disrupts internal activities. The internet provider (Inode) was not able to help, as they insisted their side of the network was working fine. The company urgently requests a fix as it is both cumbersome for them and there is only one person who has the login credentials to the server and knows how to administer the (current) fix.
