get oracle database port

Hello,

I try to get oracle database port, the below script works if there is only one database by server.
How can I modify it for several databases :

#!/bin/sh

export ORAENV_ASK=NO
for BASE in $(ps -ef | grep pmon | grep -v "grep" | grep -v "awk" | grep -v "ASM" | awk -F "pmon_"  '{print$2} ')
do
export ORACLE_SID=$BASE
. oraenv $BASE


 ps -eaf | grep -v -E "grep|ps" | grep -i "tnslsnr" >/dev/null 2>&1
        if [ 0 -eq $? ]
        then
                TNSLSNRPID=$(ps -eaf | grep -v -E "grep|ps" | grep -i "tnslsnr" |\
                awk '{
                        print $2;
                }')
                export PORT_NAME=$(lsof -p $TNSLSNRPID 2>&1 |\
                awk '{
                        if ( "(LISTEN)" == $NF )
                        {
                                printf( "%s\n", substr( $(NF-1), 3) );
                        }
                }')
                port=$(awk '{
                        if ( index( $0, ENVIRON["PORT_NAME"]) )
                        {
                                if ( index( $0, "/tcp") )
                                {
                                        printf( "%s\n", substr( $2, 0, index( $2, "/")-1) );
                                }
                        }
                }' /etc/services)
              
        else
                ps -eaf | grep -v -E "grep|ps" | grep -i "tnslsnr"
fi

Thank you

Typically, all databases use the same port for the listener. In my experience, it is pretty rare to be using more than one listener.

I totally agree with johnsone! Whereas it is possible to run multiple Listeners....

Yes there are several listeners on servers thank you

This depends on your OS.

Here's a Ubuntu example looking for all IPs + Ports where dnsmasq is listening...

net16 # netstat -pluten | grep dnsmasq

Thank you the goal is to get oracle database port and by listener.

Alex [***Alex140181***]

There is no "oracle database port"!

There is one Listener running on the server, which establishes the connections to the database... In rare cases, there may be more than 1 of those running at the same time on the same server....

several listeners and several databases thank you

Good luck. Multiple listeners is a maintenance nightmare.
