It seems the port 10621 is already in use by some other process and hence the error was observed.

SOLUTION:

Step 1) Find the process ID  which is using port 10621 using below script.

__________________________

#!/bin/bash

# is the port we are looking for

if [ $# -lt 1 ]

then

echo "Please provide a port number parameter for this script"

echo "e.g. %content 1521"

exit

fi

echo "We are checking , please be patient (CTRL+C breaks) . "

for i in `ls /proc`

do

pfiles $i | grep AF_INET | grep $1

if [ $? -eq 0 ]

then

echo Is owned by pid $i

echo ..

fi

done

______________________________

Step 2) Save above mentioned script as shell script(.sh)

Eg: find_pid_with_port.sh

Step 3) Execute script as below

$./find_pid_with_port.sh 10621 ( since we need to find process holding on port 10621)

O/P:

pfiles: permission denied: 6

pfiles: permission denied: 607

pfiles: permission denied: 862

sockname: AF_INET 192.168.8.9 port:10621

Is owned by pid 8856

Step 4) In Step 3 we found PID which is holding port 10621

So we can kill that process id(PID)

$kill -9 8856

Step 5) Try starting OHS again and it comes up with no issues.

$cd $OHS_HOME/instances/$INSTANCE_NAME/bin

$./opmnctl startall

Note: Same steps are applicable for any ports and 10621 is example port here.
