静态监听，SYS用户远程连接不上，提示ORA-01031: insufficient privileges

今天QQ群里有位朋友，在配置静态监听后，使用该静态监听远程连接未打开的数据库，提示如下：

[oracle@target admin]$ sqlplus sys/oracle@orcl as sysdba 

SQL*Plus: Release 11.2.0.3.0 Production on Mon Nov 18 15:41:27 2013

ERROR:

确认过监听正常：

[oracle@target admin]$ lsnrctl status

listener.ora与tnsnames.ora配置如下：

[oracle@target admin]$ cat listener.ora 

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

   (SID_LIST =

    (SID_DESC =

    (SID_NAME = PLSExtProc)

    (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

    (PROGRAM = extproc)

    ) 

    (SID_DESC =

      (GLOBAL_DBNAME = orcl2)

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = ORCL)  －－最终问题改成小写orcl解决了

    )

  )

LISTENER =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.64)(PORT = 1521))

  )

ADR_BASE_LISTENER = /u01/app/oracle

[oracle@target admin]$ cat tnsnames.ora 

orcl =

  (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.64)(PORT = 1521))    

      (CONNECT_DATA =   

      (SERVER = DEDICATED)      

      (SERVICE_NAME = orcl2)    

      )  

  )

看配置也没什么问题，后来把上面标红部分改成小写，就OK了，真是坑爹啊。
