Hello,

I am running this script for hotbackup using RMAN

RMAN> run
2> {allocate channel c0 type disk format '/apps/oracle/admin/DBA/backup/DBA_%u_%s_%p';
3> backup
4> (database include current controlfile);
5> backup (archivelog all delete input);
6> }

And I am getting this error, this script used to run file earlier.

Here is the error:
RMAN-03022: compiling command: allocate
RMAN-03023: executing command: allocate
RMAN-08030: allocated channel: c0

What is the reason. Any help is highly appreciated.
