ORA-01017 invalid username/password logon denied (using SERVICE_NAME)

Question

I get "ORA-01017 invalid username/password logon denied" just when I use SERVICE_NAME in sqlplus sentence, without using it works fine.

USING SERVICE_NAME in sqlplus sentence:

# sqlplus sys/password@orcl as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Mon Jul 11 13:46:45 2022
Copyright (c) 1982, 2011, Oracle.  All rights reserved.

ERROR:
ORA-01017: invalid username/password; logon denied

without using SERVICE_NAME in the sentence, it works.

# sqlplus sys/password as sysdba

tnsping SERVICE_NAME is working properly:

# tnsping orcl

Used parameter files:

Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORCL)))
OK (0 msec)

current tnsnames.ora configuration

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ORCL)
    )
  )

Any ideas? Thanks in advance
