作为数据库管理员大部分时候要创建自己的数据库实例，for rman或者更改db_block_size等,但手工建库步骤复杂,令人生畏,所以找了个脚本供大家参考,脚本上有各个步骤地说明,比较好用!
手工创建数据库的全部脚本及说明
系统环境：
1、操作系统：Windows 2000 Server，机器内存128M
2、数据库： Oracle 8i R2 (8.1.6) for NT 企业版
3、安装路径：D:\ORACLE
建库步骤：
1、手工创建相关目录
D:\Oracle\admin\test
D:\Oracle\admin\test\adhoc
D:\Oracle\admin\test\bdump
D:\Oracle\admin\test\cdump
D:\Oracle\admin\test\create
D:\Oracle\admin\test\exp
D:\Oracle\admin\test\pfile
D:\Oracle\admin\test\udump
D:\Oracle\oradata\test
D:\Oracle\oradata\test\archive
2、手工创建初始化启动参数文件：D:\Oracle\admin\test\pfile\inittest.ora，内容：
3、手工创建D:\Oracle\Ora81\DATABASE\inittest.ora文件，
内容：IFILE='D:\Oracle\admin\test\pfile\inittest.ora'
4、使用orapwd.exe命令，创建D:\Oracle\Ora81\DATABASE\PWDtest.ora
命令：D:\Oracle\Ora81\bin\orapwd file=D:\Oracle\Ora81\DATABASE\PWDtest.ora password=ORACLE entries=5
5、通过oradim.exe命令，在服务里生成一个新的实例管理服务，启动方式为手工
set ORACLE_SID=test
D:\Oracle\Ora81\bin\oradim -new -sid test -startmode manual -pfile "D:\Oracle\admin\test\pfile\inittest.ora"
6、生成各种数据库对象
D:\>svrmgrl
--创建数据库
connect INTERNAL/oracle
startup nomount pfile="D:\Oracle\admin\test\pfile\inittest.ora"
CREATE DATABASE test
LOGFILE 'D:\Oracle\oradata\test\redo01.log' SIZE 2048K,
'D:\Oracle\oradata\test\redo02.log' SIZE 2048K,
'D:\Oracle\oradata\test\redo03.log' SIZE 2048K
MAXLOGFILES 32
MAXLOGMEMBERS 2
MAXLOGHISTORY 1
DATAFILE 'D:\Oracle\oradata\test\system01.dbf' SIZE 58M REUSE AUTOEXTEND ON NEXT 640K
MAXDATAFILES 254
MAXINSTANCES 1
CHARACTER SET ZHS16GBK
NATIONAL CHARACTER SET ZHS16GBK;
控制文件、日志文件在上面语句执行时生成
connect INTERNAL/oracle
