Hi all;
If I already set the parameter for the instance I want to backup as follow:
RMAN> configure channel device type disk format 'Z:\RMANTEST\%d_DB_%u_%s_%p';
question: how can I undo that parameter, the reason is I want to split the backup to 3,4 different channel.
thanks
You have to use more than one channel.Quote:

thanks Jeff as usual.
when I did what you recommended, I got the below error:
RMAN> allocate channel c1 type disk format 'z:\rmantest';

The exact syntax would be
allocate channel c1 type disk format 'Z:\oraback\%d_DB_%u_%s_%p';
Jeff,
could you please tell me what happened here ????
there is a folder backup under c driveCode:RMAN> CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'C:\BACKUP\BACKUP_%U';
old RMAN configuration parameters:
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'C:\RMANTEST\BACKUP_%U';
new RMAN configuration parameters:
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT 'C:\BACKUP\BACKUP_%U';
new RMAN configuration parameters are successfully stored

jEFF,
I got it. the backup location has to be local as the database server.
the next question is "HOW CAN WE BACKUP THE DATABASE TO SOME OTHER SERVER ON THE NETWORK (WE DON'T HAVE ANY STORAGE SYSTEM AT THE MOMMENT).
hmm, dunno. I don't do windoz. I know with NFS this works like a charm because I backup about 2TB every night with it.Quote:

1)You can undo the parameter in the following 2 ways
a)Use the following command to configure the RMAN parameters
RMAN>configure channel device type disk;
Dont give the format and the destination.
b)In the RMAN script, forcibly use the following command to overwrite the RMAN configuration done.
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup database format 'Z:\RMANTEST\%d_DB_%u_%s_%p';
