Query for help by specifying the following options: -h | -help

例子如下：

下面-redoLogFileSize 50預設也是以M為單位，不要加上M了，否則會報錯。

-automaticMemoryManagement 
-totalMemory <memory allocated for Oracle in MB>

如果上面兩個引數同時加了，也會報錯。我的例子中只加了個-totalMemory 

下面的這個東西就是咱們在建庫的時候選擇的模板，general purpose還是Data warehouing還是custom。

General_Purpose.dbc

這個東西在這下面$ORACLE_HOME/assistants/dbca/templates

Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/ora11g/ora11g.log" for further details.
[[email protected] ~]$ 

-datafileDestination /u01/app/oracle/oradata/ora11g  ---->>>>我這個路徑多加了個ora11g,其實它會自己建立目錄，不用指定名字，我加了之後就會在這下面再建一個ora11g,

只需要給他指定目錄即可/u01/app/oracle/oradata/，他自動會建以例項名的目錄，存放資料庫檔案。

如果引數較多，覺得麻煩，可以搞一個responseFile方便。

總之，圖形介面也是調的命令，用圖形介面能做到的事情，命令介面一樣可以做到，只是使用習慣的問題。

順便說下，想看官檔在這裡：

Administrator's Guide --->>>Creating and Configuring an Oracle Database--->>>Creating a Database with DBCA

有些人幹了N年了，也考了OCM，就會查個Metalink,連官檔在電腦上都沒有離線存一份，更不要說有多麼熟悉官檔了，一旦沒有網路，MOS上沒有相應案例，手機查不到，官檔哪個地方不知道，那就等著被鄙視吧。

現在11gR2的官檔基本上已經不更新了，最新版是E11882_01,最新的是11.2.0.4的，11204也新加了一些功能。下載地址在這裡：
