篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了oracle12c 多租户管理三（监听）相关的知识，希望对你有一定的参考价值。

一、local_listener参数说明

1、By default, the PMON process registers service information with its local listener on the default local address of TCP/IP, port 1521

2、To have PMON register with a local listener that does not use TCP/IP, port 1521, configure the LOCAL_LISTENER parameter in the initialization parameter file to locate the local listener.

二、动态注册
2.1、使用默认端口,非默认监听名
1、监听文件内容如下
[oracle@oracle18c1 admin]$ cat listener.ora

mycdb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.5.40)(PORT = 1521))
)

[oracle@oracle18c1 admin]$ /sbin/ifconfig -a
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.5.40 netmask 255.255.255.0 broadcast 192.168.5.255
inet6 fe80::20c:29ff:fe3b:ab57 prefixlen 64 scopeid 0x20<link>

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 833 bytes 112696 (110.0 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

2、启动监听mycdb
[oracle@oracle18c1 admin]$ lsnrctl start mycdb

3、修改local_listener

SQL> alter system set local_listener=‘(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.5.40)(PORT=1521)))‘;

System altered.

3、发起快速注册命令
SQL> alter system register;

System altered.

4、查看监听状态

三、静态注册
1、注意事项
GLOBAL_DBNAME=容器的名字
Sid 输入容器的实例名字
2、监听文件内容如下
[oracle@oracle18c1 admin]$ cat listener.ora

SID_LIST_mycdb =
