ORA-12505: TNS: 监听程序当前无法识别连接描述符中所给出的 SID

webconfig

   

tnsnames.ora 配置：

BB=
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.44.151)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = AA
    )
  )

问题原因

BB是plsql登陆的别名,sid是     (SERVICE_NAME = AA)

webconfig  sid换成AA
