Space usage in the flash recovery area is automatically monitored by Oracle database. Warning messages are written to the alert logs when the space usage has reached 85% and a critical warning is issued when the space usage nears 97%. Oracle also removes files that are on the obsolete file list when there is less than 10 percent free space available. Alternatively dba_outstanding_alerts view can be queried to get the details about the warnings and suggested actions:
SQL> SELECT OBJECT_TYPE, MESSAGE_TYPE, MESSAGE_LEVEL,
Restoring involves copying backup files from secondary storage (backup media) to disk. This can be done to replace damaged files or to copy/move a database to a new location. The data file is at a prior point of time than the current database.
Recovery is the process of applying redo logs to the database to roll it forward. One can roll-forward until a specific point-in-time, or roll-forward until the last transaction recorded in the log files.
You can run the below sql command to find the alert log location of your database instance:
SQL> select value from v$parameter where name=’background_dump_dest’;
[oracle@oracle trace]$ ls
alert_orcl.log orcl_arc2_6924.trc orcl_cjq0_4073.trc orcl_dbw0_4004.trc orcl_j001_3624.trc
or run the below sql command:
SQL> show parameter background_dump_dest
NAME TYPE VALUE
———————————— ———– ——————————
background_dump_dest string /u01/app/oracle/diag/rdbms/orcl/orcl/trace
