What steps do I need to take for a hot backup of an Oracle 9i database running on Linux?

What steps do I need to take for a hot backup of an Oracle 9i database running on Linux?
I would use RMAN to perform a hot backup of my Oracle database. Startup RMAN at the command line prompt similar to the following:
rman target / as sysdba
Once connected to RMAN run the following script:
run {
allocate channel t1 type disk format '/directory/%d_FULL_%U'; 
backup database; backup current controlfile; release channel t1; }
There are many, many options available to you with RMAN. I strongly recommend reading the Recovery Manager documentation so that you understand how to use RMAN for both backup and recovery. In addition, you should test various recovery scenarios.
