Listener Issues - TNS_ADMIN parameter

If you face listener Issues make sure that TNS_ADMIN parameter is set in your DB environment


setenv TNS_ADMIN /oracle/SID/102_64/network/admin

also you may use


tnsping SID to test (It should be running) (Your listener should be up)

We faced the situation when we were using dbua for upgrading oracle. DBUA uses tnsping, also tnsnames.ora should be set correctly

How to free MDM Port

Our MDM Server uses port 20005 and if it is busy it wont start, it means some other application is waiting for the port.

we find out by this command

netstat -a | grep 20005

if it gives FINWAIT_1 then it is OK it will get free in some time, but if it gives FINWAIT_2 then we need to free the same manually

After analysis we found the destination host where three EP server are hosted EP1, EP2 and EP3

we logged on to each one and found which process is looking keeping busy port 20005, with below command

lsof -i | 20005

on EP3 we found the process

killed the process by kill -9 pid

Now the port became free :)
