Setup Oracle Database Archivelog mode

A short musical video tutorial showing how easily you can configure Oracle Database to use archivelog mode. Using archivelog mode is highly recommended in any production database and allows RMAN hot backups (online backups) . You can also use RMAN without archivelog, but you’ll have to shutdown the database to backup it (cold backup).

Let’s system of a down :) Beware… highly advisable to TURN OFF sound if you don’t like hard rock :P

can be done easily with the following statements:

SQL> shutdown immediate;

SQL> startup mount;

SQL> alter database archivelog;

SQL> alter database open;

If your database version is prior 10g then after shutdown and before open database you must set log_archive_start = TRUE in your init.ora and/or spfile.ora. After that, login as "sys" and you can check it out with:

SQL> archive log list;

SQL> select log_mode from v$database;

Note: In this case, we need to do a quick restart of the database to enable it to "Archive Log Mode". So please ensure your the required outage window.
