Home -> Community -> Mailing Lists -> Oracle-L -> RE: archive log curr v. switch logfile
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 ; #

PS. Confident w/ hot backups, next to conquer RMAN cautiously.
>>> lisa.koivu_at_efairfield.com 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 .
