Installation is done.

After installation I got tns listener error
then I tried these steps to fix the error and its working fine
On cmd prompt
set ORACLE_HOME=c:\oracle\ora11g
path=c:oracle\ora11g\bin;(path should contain bin folder)
set ORACLE_SID=orcl
set system environment variables also
restart pc

tnsping orcl

Add one line to the WINDOWS/SYSTEM32/DRIVERS/ETC/HOSTS FILE
IP_address hostname.domainname hostname
LISTENER.ORA
make sure host name is correct
tnsnames.ora
sqlnet.ora
