Thanks a lot

If you don’t mind I can share some addition info with this post.

If you want to find the port list of oracle application and database in Linux system use the following command.

# cat $ORACLE_HOME/install/portlist.ini

Else, you can follow this guide to find out Oracle ports: https://docs.oracle.com/cd/B19306_01/install.102/b15660/app_port.htm

Thanks again…

@Mike

Thanks for sharing, I use a similar command to find process listening on a port like this:

$ sudo netstat -tnlp | grep -w "PORT_HERE"

Where:

  • -t – consider tcp ports.
  • -l – display only listening sockets.
  • -n – show numerical addresses.
  • -p – show the PID and name of the program socket belongs to.

I remember “ant” and “lp” options for some reason it sticks in my brain.
