oracle tnsnames.ora 区分大小写？

问题：客户端Net Manager服务命名无反应，且PL/SQL无法连接本地数据库（远程连接无问题） ；另enterprise manager console 添加新的数据库会报TNS-04605错误

客户端tnsnames.ora中：
PADIS =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.180.170)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = pdais)
    )
  )

服务端tnsnames.ora中：
PADIS =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.180.170)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = PADIS)
    )
  )

 处理：将客户端小写改为大写（或将客户端tnsnames.ora配置替换为服务端tnsnames.ora配置）
