博客介绍了主机mncndn1上存在两个实例的情况，接着说明了配置监听文件，netca默认创建1521端口的listener.ora文件后，又配置了名为LISTENER1、端口为1522的监听，最后提及查看1522端口和1521默认端口的监听注册情况。

1、主机mncndn1上存在两个实例

-bash-4.1$ hostname
mncndn1
-bash-4.1$ ps -ef |grep pmon
oracle     3788      1  0 05:46 ?        00:00:02 ora_pmon_QXY
oracle    92205      1  0 09:10 ?        00:00:00 ora_pmon_XTTS
oracle    98117  61181  0 09:15 pts/0    00:00:00 grep pmon
-bash-4.1$

2、配置监听文件

netca默认创建1521之后的listener.ora文件内容

-bash-4.1$ cat listener.ora 
# listener.ora Network Configuration File: /srv/BigData/mppdb/data1/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = mncndn1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /srv/BigData/mppdb/data1

配置多一个监听名字为LISTENER1，端口为1522。

-bash-4.1$ cat listener.ora 
# listener.ora Network Configuration File: /srv/BigData/mppdb/data1/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = mncndn1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )


SID_LIST_LISTENER1 =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = QXY)
      (ORACLE_HOME = /srv/BigData/mppdb/data1/product/11.2.0/dbhome_1)
      (SID_NAME = QXY)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = XTTS)
      (ORACLE_HOME = /srv/BigData/mppdb/data1/product/11.2.0/dbhome_1)
      (SID_NAME = XTTS)
    )
  )
LISTENER1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = mncndn1)(PORT = 1522))
    )
  )

ADR_BASE_LISTENER = /srv/BigData/mppdb/data1

3、查看监听注册情况

1522端口

-bash-4.1$ lsnrctl status LISTENER1
