Steps to create database manually

1.create Pfile from the dummy file.The Pfile(init.ora)is in ORACLE_HOME/dbs.

2.create required number of directories.

3.startup nomount

4.create database script & execute it.

5.execute the following scripts to create default profiles, functions, procedures, views, synonyms

etc.

                i)catalog.sql

                ii)catproc.sql

                iii)connect to system/manager

                iv)pupbld.sql
