配置监听listener文件：
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.100)(PORT = 1523))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1523))
    )
  )

SID_LIST_LISTENER=
(SID_LIST=
  (SID_DESC =
  (GLOBAL_DBNAME = orcl12c)   #CDB信息
  (SID_NAME = orcl12c)
  )

  (SID_DESC =
  (GLOBAL_DBNAME = polestar1) #PDB信息
  (SID_NAME = orcl12c)
  )
)

用创建用户连接pdb数据库
