Kdiff comparison result for the oracle configuration files

Here is the kdiff comparison output for the three configuration files(listener.ora,sqlnet.ora,tnsnames.ora) that lead me to lose lot of time...Here it is,

listener.ora kdiff comparison output

tnsnames.ora kdiff comparison output

sqlnet.ora kdiff comparison output

You can find out the difference in those files in old and new...the new one is working fine. so that you can make the necessary changes as needed.
