[20160418]修改oracle監聽埠.txt

--上午開發提出要修改oracle的監聽埠,我以前測試遇到過一些問題:
--連結: http://blog.itpub.net/267265/viewspace-758983/
-- 但是在11.2.0.4下遇到以前不一樣的情況,時間太久了,測試在2013年做的,也許現在存在一些變化.

1.無靜態註冊監聽:

--這個時候可以動態註冊.執行如下可以登入,看來以前11.2.0.3測試存在的問題實際上是一個bug.
$ sqlplus -L scott/book@192.168.100.78:1529/book

2.再看看看存在靜態監聽註冊的情況:

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

      (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 = 1529))
#      (ADDRESS = (PROTOCOL = TCP)(HOST = gxqyydg4)(PORT = 1529))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle
DIAG_ADR_ENABLED_LISTENER=OFF

SYS@book> alter system set local_listener='' scope=memory ;

--如果害怕影響,最好的方法就是重啟資料庫.

SYS@book> alter system register ;
System altered.

$ sqlplus -L scott/book@192.168.100.78:1529/book => 透過ok
$ sqlplus -L scott/book@192.168.100.78:1521/book => 報錯ORA-12541.

3.總結：
1.看來以前在11.2.0.3遇到的問題,應該是bug.
2.要使用非標準埠，可以使用靜態註冊。這樣可以不要修改引數local_listener.但是動態註冊1521埠無效，也就是無法再透過1521
  埠連線資料庫。
3.使用非標準埠,如果使用非靜態註冊,必須修改local_listener引數，讓動態註冊使用非標準的埠來實現,這樣就無法使用1521埠。
4.總之,修改監聽的預設埠,無法再使用1521埠連線資料庫.
5.看來以前遇到的是bug.要以動態的態度看待oracle,不能報老經驗,一句話最好的方法就是測試.

--另外我還發現一些問題,如果配置靜態監聽並且使用1521埠:

--我還開啟了http 8888,以及ftp的7777埠.而如果使用非標準埠,是看不到了http 8888,以及ftp的7777.
