I use Alter system archive log current. If your archiver process is caught up, you will get this error message when issuing Alter system archive log all:
SQL> alter system archive log all; alter system archive log all * ERROR at line 1: ORA-00271: there are no logs that need archiving Just don't like error messages in the logs :). Lisa's method seems the safest, but never had an archiver not keeping up and if I did, that would be an issue to be resolved quickly. Here's my hot backup model with help from list members and Velpuri/Adkoli's Backup/Recovery Book: # 1) Alter system archive log current ; # 2) Check backup status. # 3) Generate datafile listing. # 4) Alter tablespace <tablespace_name> begin backup ; # 5) Some other process,script,legato,etc. will copy database files # to disk or to tape. # 6) Alter tablespace <tablespace_name> end backup ; # 7) Backup controlfile. # 8) Alter system archive log current ; # Archives are backed up separately 2 x day to tape. Gene PS. Confident w/ hot backups, next to conquer RMAN cautiously. >>> [EMAIL PROTECTED] 03/29/02 12:13PM >>> Actually I use alter system archive log all. I saw that if the database was behind with archiving, this would ensure that all logs were written to the arc destination. archive log current only did the most recent. Am I wrong? Please correct me if I am .
