3，修改监听端口号（端口修改为8521）
[oracle@DSJ-RTB-4T-349 admin]$ cd $ORACLE_HOME/network/admin/
[oracle@DSJ-RTB-4T-349 admin]$ vim listener.ora
[oracle@DSJ-RTB-4T-349 admin]$ cat listener.ora
# listener.ora Network Configuration File: /data/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /data/app/oracle/product/11.2.0/dbhome_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 8521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
#----ADDED BY TNSLSNR 11-APR-2018 16:08:51---

#--------------------------------------------
[oracle@DSJ-RTB-4T-349 admin]$ vi tnsnames.ora
[oracle@DSJ-RTB-4T-349 admin]$ cat tnsnames.ora
DWCA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 8521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dwca)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =

)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
LISTENER_DWCA =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
4，修改初始化参数local_listener
[oracle@DSJ-RTB-4T-349 admin]$ sqlplus / as sysdba;

5，开启监听
