Configure VNC On Oracle Database Appliance

Introduction:

To Deploy ODA you need GUI interface, to do this you make use of VNC server to connect with ODA and open GUI interface.

In this article I will demonstrate how to configure VNC on Oracle Database Appliance.

Configure VNC:

You can access database servers remotely by using tools such as PuTTY and Virtual Network Computing (VNC) which are freely available for download.

In most cases, accessing a database server in a command-line mode via PuTTY is enough. Sometimes we may need to access a database server to run GUI-based software. For example, to run runInstaller to install Oracle software or DBCA to create databases. In these cases, VNC a cool tool for running GUI-based sofware.

VNC allows you to run GUI interface on database server. It allows you to execute programs locally on the server, while only the screen output is sent to the VNC client on your desktop.

On ODA you can configure VNC in two ways:

1. startx command
2. vncserver command

Using startx command:

- Login to ILOM as super user (root) and execute startx command

- VNC screen is displayed

- Execute "oakcli deploy" to test GUI access

- Left click and exit to return back to ILOM session

 

Using vncserver command:

- Login to database server as Suport user (root), Check if vnc servers is running, Execute vncserver command to start vnc. Enter the root password first time and enter again to verify. Check if vnc server is started and note down the port number.

- Download VNC-Viewer and Click on VNC-Viewer on desktop

- ON VNC-Viewer page enter the ODA Node IP or hostname along with VNC server port

- Click Continue

- Enter the root password

- VNC screen is displayed

- Execute "oakcli deploy" to test GUI access

- Left click and exit to return back to ILOM session

Conclusion:

In this article we have learned about VNC and how to configure VNC on Oracle Database Appliance. Configure VNC is simple and straight forward. VNC comes handy when you want to run GUI-Based applications. To Deploy ODA you need GUI interface, to do this you make use of VNC server to connect with ODA and open GUI interface.
