Typical - I go on holiday for day and somebody generates an abnormal load of archived logs. They filled up the disk, moved the wrong files then moved the right files - did a reboot and hey presto although the DB comes up fine I discover that an archived log is missing.Thats my standby trashed! Assuming the non use the rm command anyone got an idea how it happened? OS Redhat Linux DB Version 10g -- Howard A. Latham DBA RSMB TV Research London, England
