[20160711]关闭监听的动态注册.txt

--这个我给别人解决dg日志不应用的问题.问题是没有设置静态注册,又关闭动态注册.自己还第一次知道存在这个参数
--DYNAMIC_REGISTRATION_LISTENER = off
--再测试环境重复测试,做1个记录:

1.环境:
SCOTT@book> @ &r/ver1

PORT_STRING                    VERSION        BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx            11.2.0.4.0     Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

2.修改监听文件:
$ cat  listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

#SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF

#SID_LIST_LISTENER =
#   (SID_LIST =
#    (SID_DESC =
#      (SDU=32767)
#      (GLOBAL_DBNAME = book)
#      (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)
#      (SID_NAME = book)
#      )
#    )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.100.78)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle
DIAG_ADR_ENABLED_LISTENER=OFF
DYNAMIC_REGISTRATION_LISTENER = off

3.重启监听:
$ lsnrctl stop
$ lsnrctl start
SCOTT@book> alter system register ;
System altered.

$ lsnrctl status

4.这样其他机器无法远程登陆.

--主要问题,单位要通过安全等保,设置这个参数,没有仔细测试,做dg时又没有配置静态监听注册,而导致的问题.
--设置静态监听注册,问题解决.
--只所以一直没出现问题，是因为监听没有重启或者reload。从另外一些也说明，对服务器做了什么改动，要有记录有据可查。

--不知道为什么做安全等保要设置这个参数.有什么好处?我自己不知道.

--取消注解：
SID_LIST_LISTENER =
   (SID_LIST =
    (SID_DESC =
      (SDU=32767)
      (GLOBAL_DBNAME = book)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)
      (SID_NAME = book)
      )
    )
