Oracle available Ports for Listener

[vr76413]

Hi all..
Sun 5.8

I using 1521 for Oracle 8.1.7 and 1526 for Oracle 9.2. These 2 versions are installed under Different Accounts. Now i need to Install 9.0.1 on the same server with another Account.

so my question is Which are the ports i can use now for Listener to communicate for the 3rd version iam going to Install ?..

Thanks for all your help

You can use any port you wish.

As Julian says you can use any port you wish (providing it is not aleady being used) or another option would be to use a single listener to cover all versions.

You can use any port that isn't already used. You might try port 1528. Look at the netstat command. It will tell you what ports are in use. I think you want the port number to be over 1200, but I'm not sure. You need root access for any port under that number.

how do we find out which ports are available ?....Sun 5.8

Take a look in /etc/services (providing you have kept it upto date)

or

netstat -a

will give you the information on sockets in use.

I don't thing that using ports lower then 1000 is a good sugestions.
It possible but in any way this isn't good decigion.
Any # of a port lover then 1000 - is a root's port.
