Default Port Numbers Used on Exadata: Port Numbers for General Use Part 1 of 3

network_port

There are many ports that need to be opened in firewall to allow certain types of communication on Exadata. Here is the list of the port numbers. Note: all ports below are on the management work with the only exception of port number 1521, which is on client or public network.

         Cell                 TCP        7799    OEM HTTPS console port

The above port list is based on the document Default Service Ports for Exadata and Cloud Control /Enterprise Manager Configurations (Doc ID 1532838.1).

For me, it is not easy to figure out which port should be open on which hardware component. So I use Excel spreadsheet to create a matrix to show ports used on Exadata.

In the future, I will have another two posts discussing ports used by ILOM and OEM.
