添加监听修改local_listener时报错ORA-00119、ORA-00132

系统：windows server 2008 r2
数据库：oracle 11.2.0.1
问题描述：在添加监听修改local_listener时报错ORA-00119、ORA-00132，如下所示：
SQL> show parameter local_list

NAME                                 TYPE                   VALUE
------------------------------------ ---------------------- ------------------------------
local_listener                       string                 LISTENER_ORCL
SQL> alter system set local_listener='LISTENER_ORCL,LISTENER2';
alter system set local_listener='LISTENER_ORCL,LISTENER2'
*
第 1 行出现错误:
ORA-02097: 无法修改参数, 因为指定的值无效
ORA-00119: 系统参数 LOCAL_LISTENER 的说明无效
ORA-00132: 语法错误或无法解析的网络名称 'LISTENER_ORCL,LISTENER2'

解决方案：
SQL> alter system set local_listener='(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.192)(PORT = 1521))','(ADDRESS = (PR
OTOCOL = TCP)(HOST = 192.168.133.192)(PORT = 1561))';

系统已更改。

以下为tnsnames.ora文件.
# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
   (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.192)(PORT = 1521))

LISTENER2 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.192)(PORT = 1561))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.133.192)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

说明：LISTENER2为新添加监听.
