I create three SQL scripts
1.shutdown.sql
2.startup.sql
3.copy.sql
----------------
Content of files.
1.shutown.sql
cmd>sqlplus "/@db01 as sysdba"
SQL>set headning off echo off verify off feedback off pagesize 0
SQL>spool d:\bkp_scripts\db01\shutdown.sql
SQL>PROMPT shutdown immediate;

SQL>PROMPT exit;
exit
SQL>spool off;
-----------------------------------
2.startup.sql
cmd>sqlplus "/@db01 as sysdba"
SQL>set heading off echo off verify off feedback off pagesize 0
SQL>spool d:\bkp_scripts\db01\startup.sql
SQL>PROMPT startup open pfile=d:\oracle\product\10.1.0\db_1\database\initDB01.ora
startup open pfile=d:\oracle\product\10.1.0\db_1\database\initDB01.ora
SQL>exit;
exit
SQL>spool off;
--------------------------------------------
3.copy.sql
cmd>sqlplus "/@db01 as sysdba"
SQL>spool d:\bkp_scripts\db01\copy.sql
SQL> select ' host COPY ' || name || ' d:\coldbkp_db01\ ' from v$datafile

exit
SQL> spool off
----------------------------------------------------------------
I schedule my backup every friday 11 pm. i create COLDBKP.CMD file
4.coldbkp.cmd
e:\oracle\ora90\bin\sqlplus -S "/@db01 as sysdba" @d:\bkp_scripts\db01\shutdown.sql
e:\oracle\ora90\bin\sqlplus -S "/@db01 as sysdba" @d:\bkp_scripts\db01\copy.sql
e:\oracle\ora90\bin\sqlplus -S "/@db01 as sysdba" @d:\bkp_scripts\db01\startup.sql
-------------------------------------------------------
Schedule through SCHEDULE TASK windows utility.

Note : above scripts is my own workshop example. Test first any scripts before using.i am not responsible for any damage.


Note : If you don't include redolog files in COLD BACKUP. then you must open your database with RESETLOGS ( recover database through COLDBACKUP)

Hello!?
The copy command does not work in Ms Windows Server before Ms Windows Server 2003.
You must use the ocopy which Oracle are provided.

Hi,
The copy command does not work in Ms Windows Server before Ms Windows Server 2003.

I don't think because above scripts tested in Windows XP sp2. and it is working correctly.

And if you take HOT BACKUP then MS Windows COPY command is not copy open database files that time you have to use OCOPY command.

Before WinXP i was not tested COPY command.

anyway thank for your suggestion.
i will edit my post with your comments.

regards
Taj
