I found this in my alert_ora1.log

Tue May 1 13:09:19 2001
ORACLE Instance ora1 - Can not allocate log, archival required

Thread 1 cannot allocate new log, sequence 584
All online logs needed archiving
Current log# 1 seq# 583 mem# 0: /data1/oradata/ora1/redo01.log

My guess is that I need to archive my redo log files. How do I go about this? Should I turn my AutoArchival to true? If so, how do I do this?
