Enabling archived logging

When you set the database to the archived logging mode, you protect the unsaved
online redo logs from being overwritten. Online backup of data files is useless without
the related redo logs because you cannot recover the database to a consistent state.

TIP:

Archive the redo log files generated during the online backup immediately after
BRBACKUP completes.

To protect the archive directory from overflowing, clear the directory regularly.

To enable archived logging:

1.

In the

init

ORACLE_SID

.ora

file, set

log_archive_start = true

and specify the

log_archive_dest

option.

Example

This is an example of the

init

ORACLE_SID

.ora

file for the Oracle instance

PRO
