1. Using Database configuration assistant. Start -> run -> type " Dbca"

2. manually crated database using Command based method.

Here i have used manually cteated.

1. Create folder in %ORACLE_BASE%/admin/

%ORACLE_BASE%\admin>mkdir iso
%ORACLE_BASE%\admin>cd iso
%ORACLE_BASE%\admin\iso>mkdir adump
%ORACLE_BASE%\admin\iso>mkdir bdump
%ORACLE_BASE%\admin\iso>mkdir cdump
%ORACLE_BASE%\admin\iso>mkdir dpdump
%ORACLE_BASE%\admin\iso>mkdir pfile
%ORACLE_BASE%\admin\iso>mkdir scripts
%ORACLE_BASE%\admin\iso>mkdir udump

Here "ISO" is a my database name.

2. set oracle enviorment variable

F:\>set oracle_sid=iso

3. create password file for iso database

F:\>orapwd file=F:\oracle\product\10.2.0\db_1\database\PWDiso.ora entries=5 password=oracle force=y

4. Create Oracle instance and start your new service

F:\>oradim -new -sid iso -startmode manual

6. Here run your Database script

10240K,
15 GROUP 3 ('F:\oracle\product\10.2.0\oradata\iso\REDO03.LOG') SIZE
10240K
16 USER SYS IDENTIFIED BY "&SYSPWD"
17 USER SYSTEM IDENTIFIED BY "&SYSTEMPWD";
Enter value for syspwd: babu
old 16: USER SYS IDENTIFIED BY "&SYSPWD"
new 16: USER SYS IDENTIFIED BY "babu"
Enter value for systempwd: babu
old 17: USER SYSTEM IDENTIFIED BY "&SYSTEMPWD"
new 17: USER SYSTEM IDENTIFIED BY "babu"

7. Create user tablespace

SQL> CREATE TABLESPACE "USER" LOGGING DATAFILE 'F:\oracle\product\10.2.0\oradata\iso\USERS01.DBF' SIZE 10m REUSE AUTOEXTEND ON NEXT 1280k MAXSIZE

@%ORACLE_HOME%\SQLPLUS\ADMIN\pupbld.sql

9. Finally create Spfile using your Pfile
