(ADDRESS=(PROTOCOL= IPC)(KEY = ORCL))
how can i do this .

Answer 1

It is not recommended to change the name for an IP addressIt is not recommended by who? AFAIK there is no such sentence in documentation.
But there is other:
host Required. Specify the host name or IP address of the database server computer.
Instad of "It is not recommended..." better use "Consider this..."
, as if ever it changes in the future, you'll have to be back and change once again your ip.The same is truth when we are speaking about FQDN (fully qualified domain name).
How often your company changes the IP adresses on server platform?
My experience from past:
First case:
My company has rebranded and and domain name has been changed but IP has not. Unfortunatelly we were not using OID for resolving. If there were FQDN used then would have to make changes in many files. Fortunatelly we were using IP addresses.
Now we are using OID for resolving of tnsnames (as primary method).
What I want to say is both solutions (FQDN or IP) are fine. Each of them has some advantages and also disadvantages.
