Oracle Install Error - AIX

Posted on 2011-04-27
Last Modified: 2013-11-17
I am trying to install Oracle 11g on AIX6. During the installation it wanted to assign a port for LISTENER, The default port which its using is already used to another service
# cat /etc/services |grep 1208
seagull-ais      1208/tcp               # SEAGULL AIS
seagull-ais      1208/udp               # SEAGULL AIS

When I give a random port which is not used by any program here is what I get ;

It has requested to give any port number but any port number I give I get an error saying
"Use another port number : The information provided for this listener is currently in use by another software on this computer.You can proceed with the configuration as it is but it will not be possible to start the listener untill the conflit is resolved."

    could it be that your /etc/hosts file is not configured properly?

    Is your hostname and its (correct) IP address in that file?

    I think my host file is right

     # cat /etc/hosts       loopback localhost      # loopback (lo0) name/address csc06lv005

    Is there any test I can do to know if we can use an unused port

    The 'default' port for the listener is 1521.  What is in /etc/services really doesn't matter.  It is what processes are running that is using the port in question.  They do not have to be in the services file.

    Do you already have an Oracle listener running from another Oracle install?

    If you want to run more than one, just pick a new port.

    Accepted Solution

    You can always try

    telnet hostname portnumber

    If you get

    "telnet: connect: A remote host refused an attempted connect operation."

    the port is most probably free, and if you get

    "Connected to ..."

    the port is most probably in use.

    netstat -an | grep portnumber

    should also show you whether a port is in use.
