Oracle XE, change hostname on local machine

Rightn now the hostname of machine has been changed:

hostname
right.hostname.net

Open file for modify:

vim /u01/app/oracle/product/11.2.0/xe/network/admin/listener.ora

Set right.hostname.net for:

# listener.ora Network Configuration File:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/xe)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = right.hostname.net)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

Make sure the hosts file have the right.hostname.net:

cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 right.hostname.net
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

In the same time tnsnames.ora points to 127.0.0.1:

cat /u01/app/oracle/product/11.2.0/xe/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File:

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
