而“Custom Database”自定义模式则没有对应的数据文件来恢复，而是全新创建的数据文件，因此这种方式创建实例时耗费的时间也相对较长，因为需要跑数据字典。
上面简单介绍了使用responseFile方式创建实例的方法，另外一种方法是直接使用命令行，可以用dbca -h命令查看命令参数
[oracle@rhel6 trace]$ dbca -h
dbca [-silent | -progressOnly | -customCreate] {<command> <options> } | { [<command> [options] ] -responseFile <response file > } [-continueOnNonFatalErrors <true | false>]
Please refer to the manual for details.
