<br />
you just need to enter you remote host (DB server IP and oracle port 1521) and your local port example 51521 or any you like...<br />
<br />
after that you need to edit you oracle tnsnames file and instead of ip adres of your database put localhost and the port you chose for your local port..<br />
<br />
after that after putty connects to the DB server you can use you loacl sqlplus...<br />
<br />
if you need additional explanation let me know...

Hi to all.<br />
I appreciate that you can provide me detailed instructions to perform the following:<br />
From home, I use the SafeNet Secure VPN Client to access my work. <br />
Once connected, I have to ssh to a box (let's call it 192.168.2.29), and once connected to that box, I have to ssh to another box that has the DB Server (192.168.1.28).<br />
There is any way to use my LOCAL sqlplus on my PC to access directly to the DB Server using Putty Tunnel option? <br />
So basically I'd like to access the DB Server directly from my PC (if possible).<br />
<br />
Any help is appreciated

Need step by step to Tunnel to an Oracle DB using Putty

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
