Folks,
Hello. I am using Oracle Database Server 11gR1 with Operating System Oracle Linux 5.10.
I understand how to backup database instance in SQL Server with Windows. But don't really understand how to backup database instance in Oracle with Linux.
I have done Cold backup and Hot backup for the database instance HRCS90 but both get the same error message.
Cold backup is below:
SQL> startup
ORACLE instance started.
Total System Global Area 538677248 bytes
Fixed Size 2146024 bytes
Variable Size 528482584 bytes

Database mounted.
Database opened.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
RMAN> backup database;
Starting backup at 25-NOV-13
using target database control file instead of recovery catalog

While the database instance HRCS90 is startup, I do hot backup using the same commands and get the same error message with above cold backup.
My question is:
Can any folk tell me the specific steps (command by command) to backup a single database instance in Oracle using RMAN ?
Thanks.
