Hi, Running 10.2.0.3 AIX 6 Just switched my test DB into ARCHIVELOG mode and when I attempted to backup the db to tape via rman it is complaining as follows. RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of backup command on c2 channel at 03/10/2009 13:38:13 ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode However, a quick command in sqlplus shows the following.... SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /u01/backup Oldest online log sequence 121 Next log sequence to archive 123 Current log sequence 123 SQL> select log_mode from v$database; LOG_MODE ------------ ARCHIVELOG I am confused as I have done this numerous times on other DB's and never seen this behaviour ?? Also, I have log switched a few times and my archive logs are being written to the arch area as expected. Any ideas would be appreciated as I cannot find a thing on google or Metalink.
