[20160711]關閉監聽的動態註冊.txt

--這個我給別人解決dg日誌不應用的問題.問題是沒有設定靜態註冊,又關閉動態註冊.自己還第一次知道存在這個引數
--DYNAMIC_REGISTRATION_LISTENER = off
--再測試環境重複測試,做1個記錄:

1.環境:
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.修改監聽檔案:
$ 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.重啟監聽:
$ lsnrctl stop
$ lsnrctl start
SCOTT@book> alter system register ;
System altered.

$ lsnrctl status

4.這樣其他機器無法遠端登陸.

--主要問題,單位要透過安全等保,設定這個引數,沒有仔細測試,做dg時又沒有配置靜態監聽註冊,而導致的問題.
--設定靜態監聽註冊,問題解決.
--只所以一直沒出現問題，是因為監聽沒有重啟或者reload。從另外一些也說明，對伺服器做了什麼改動，要有記錄有據可查。

--不知道為什麼做安全等保要設定這個引數.有什麼好處?我自己不知道.

--取消註解：
