我正在尝试Oracle client 12.2 in RHEL 7 linux从Python程序中对新安装进行健全性测试,但是由于上述错误而失败,不确定我在那里缺少什么.请帮忙解决这个问题:

cx_Oracle.DatabaseError: ORA-12514: TNS:listener does not currently know of service 
requested in connect descriptor

我tnsnames.ora目录下的/home文件

  FRDLD2D1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(Host = frdld2d1.de.db.com)(Port = 1825))
    )
    (CONNECT_DATA =
      (SID = FRDLD2D1)
      )
   )
