Thanks for your help.

RMAN rocks. This was a ton more work the way we were doing it.

run {
allocate channel fs1 type disk format='/home/oracle/backup/BANG/%u.bak';
allocate channel fs2 type disk format='/home/oracle/backup/BANG/%u.bak';
allocate channel fs3 type disk format='/home/oracle/backup/BANG/%u.bak';
allocate channel fs4 type disk format='/home/oracle/backup/BANG/%u.bak';

set limit channel fs1 kbytes=2000000; #limit file size to 2Gb
set limit channel fs2 kbytes=2000000;
set limit channel fs3 kbytes=2000000;
set limit channel fs4 kbytes=2000000;

backup database;

sql "alter system archive log current";

backup archivelog all delete input;

}
