I recently downloaded the SQLDeveloper and try to create a new connection, but it shows an error, like;

*Status : Failure -Test failed: IO Error: the network adapter could not establish the conection.*

The field values given by me are:

Connection Name: hr Username: hr Password: oracle Connection Type: basic Role: default Hostname: localhost Port: 1521 SID: xe

Please help me resolving this.

Thank You in Advance.

Do you have Oracle DB on installed on your machine and running?, if it is installed and running do you have SELinux set to enable to connect to the DB? if you do not know, try setting SELinux to permissive

You need to download OracleDB from Oracle site and install it, you can do it from here http://www.oracle.com/technetwork/dat... here is the documentation http://docs.oracle.com/cd/E17781_01/i... it will give you the steps to install.
