If you are trying to run any apps service (adapcctl.sh, opmnctl, lsnrctl) and get message like\u00a0 “unable to bind port <port_number><\/strong>” (Most probably this port is in use by other process), fix is to<\/strong> either start your service on different port or terminate process<\/strong> listening on that particular port using kill -9 <pid><\/strong><\/p>\n

In order to kill that specific pid, you need to find pid which is listening on that specific port. There are lot of ways to find pid which is listening\/using specific port and most commonly used is LSOF<\/strong><\/p>\n

What is lsof ?<\/u>
\n<\/strong>lsof which stands for L<\/strong>iS<\/strong>t O<\/strong>pen F<\/strong>iles is Unix utility to list all open files and processes that opened them on Unix.<\/p>\n

–
\nHow to use LSOF ?<\/u><\/strong><\/p>\n

lsof | grep <port_number><\/strong>\u00a0 ( on Solaris,<\/strong>lsof is usually installed under \/usr\/local\/bin<\/strong> where as on Linux<\/strong> its usually under \/usr\/sbin<\/strong> )<\/p>\n

Beware if you are on Solaris 10 and using ZONES<\/strong><\/font>(more on zones in solaris 10 coming soon) :
\n1. lsof doesn’t<\/strong> work from non-global zone <\/strong>in solaris 10
\n2. Use -z option <\/strong>with lsof to list open files & processes with in non-global zone<\/strong> like “lsof -z<\/strong>”
\n3. Solaris 10 with zones list doesn’t display port , hence I used script mentioned at end of this post.<\/p>\n

Once you know PID using specific port, you can either stop it or terminate using
\nkill -9 <pid><\/strong>
\n<\/u><\/strong><\/p>\n

<\/u><\/strong><\/p>\n

<\/u><\/strong><\/p>\n

Key points for lsof on solaris
\n<\/u><\/strong>
\n1) Installation procedure of lsof on solaris is same for Solaris Sparc or X86\u00a0& on\u00a0version 9 or 10 only difference is file name<\/p>\n

2) lsof doesn’t work from zone\u00a0 (More on zones in solaris 10 coming soon), You have to\u00a0install lsof\u00a0on global zone<\/strong>.\u00a0 If you run lsof and get error message like “lsof: can’t stat(\/devices): No such file or directory<\/strong>” probably you are running lsof with in solaris 10 Zone.<\/p>\n

3) lsof on solaris is installed under \/usr\/local\/bin<\/strong> (default location)<\/p>\n

4) On Solaris 10, using “lsof -i<\/strong>” to show mapping of processes to TCP ports incorrectly shows all processes that have socket open as using port 65535. (Use script mentioned at end of file in such cases<\/font>)<\/p>\n

<\/u><\/strong><\/p>\n

<\/u><\/strong><\/p>\n

How to install lsof on Solaris 10<\/u>
\n<\/strong>lsof is part of Red Hat Linux (By default its installed under \/usr\/sbin<\/strong>), for Solaris\u00a0lsof is available as freeware here<\/a>\u00a0for Solaris Sparc 10<\/strong>\u00a0download it \u00a0from here<\/a><\/p>\n

1. Download lsof executable for Solaris 10 on sparc from here<\/a>\u00a0 or from here <\/a>if you are on different processor or version.<\/p>\n

2. Upload zip file like lsof_0606-4.77-sol10-sparc-local.gz<\/strong>\u00a0 to server<\/p>\n

3. Unzip as gunzip lsof_0606-4.77-sol10-sparc-local.gz<\/strong>\u00a0 (This will create file like lsof_0606-4.77-sol10-sparc-local)<\/p>\n

4. pkgadd -d lsof_0606-4.77-sol10-sparc-local\u00a0 (Run this command from root user from global zone)<\/p>\n

<\/u><\/strong><\/p>\n

If you are on Solaris 10 use below script to list port <\/u><\/strong><\/p>\n

create file like get_pid_from_port.sh\u00a0\u00a0 (Or download script from here<\/a>)
\n<\/strong><\/p>\n

#!\/bin\/bash
\n# $1 is the port we are looking for<\/font><\/p>\n

if [ $# -lt 1 ]
\nthen
\necho “Please provide a port number parameter for this script”
\necho “e.g. $0 1521”
\nexit
\nfi<\/font><\/p>\n

echo “Greping for your port, please be patient (CTRL+C breaks) … “<\/font><\/p>\n

for i in `ls \/proc`
\ndo
\npfiles $i | grep AF_INET | grep\u00a0$ 1
\nif [ $? -eq 0 ]
\nthen
\necho Is owned by pid $i
\necho ——
\nfi
\ndone<\/font><\/p>\n

and execute this script like
\nsh get_pid_from_port.sh <port_num><\/strong>
\nsh get_pid_from_port.sh 8000 <\/strong>(To find pid using port 8000)<\/font><\/p>\n

(I got this script from net last year and now I can’t find Author of this script. In case I find authour or link I’ll remove from here and link to original site)<\/u><\/strong><\/u><\/strong><\/p>\n
