How to backup Oracle in Windows 2003 ?

You do it in a same way as with Linux which means backup command is nsrnmo* (if changing default one that nsrnmo.bat), your saveset is RMAN:path_to_rman_script.

What you listed is not nsrnmo script, but rather RMAN script... Are you sure your Linux backup works?

Anyway, check installation guide as it gives you nice step by step guide.

I write:

backup command: nsrnmo.bat

saveset: RMAN:D:\legato\nsr\bin\Rman_script.bat

I have this messages when I launch my group:
1 retry attemped
No full backups of this save were found in the media database, performing a full backup

C:\>ECHO OFF

My Rman_script:
connect target system/manager@solv
connect catalog rman/rman@rman
run{
set command id to 'xxx';
allocate channel t1 type 'SBT_TAPE';
send 'NSR_ENV=(NSR_DATA_VOLUME_POOL=Mensuel)';

backup full filesperset 4 format '/FULL_%d_%u/' (database);

release channel t1
}


Do you have any idea ?

You need to check your nsrnmo script. There is something wrong with some parameter like Oracle home, Oracle library etc here OR RMAN has not been configured on the Oracle server.

This is my nrsnmo.bat script:

Can you verify that rman binary is inside D:\oracle\ora92\bin? Because it seems to indicate it can't find rman to execute the script.
