Enabling ARCHIVELOG Mode

Check Archive is enabled or not

SQL> SELECT LOG_MODE FROM SYS.V$DATABASE;

LOG_MODE
------------
NOARCHIVELOG

Set InitSID.ora on following parameter

remote_login_passwordfile=EXCLUSIVE
log_archive_dest='/u02/oracle/backup'
log_archive_format='PROD_arch_%s_%t_%r.arc'


Create Password File

orapwd file=/u01/oramgr/PROD/db/tech_st/10.2.0/dbs/orapwPROD entries=1 password=oracle


SQL> alter database archivelog;
Database altered.

SQL> alter database open;
Database altered.


V$DATABASE

Identifies whether the database is in ARCHIVELOG or NOARCHIVELOG mode and whether MANUAL (archiving mode) has been specified.

V$ARCHIVED_LOG

Displays historical archived log information from the control file. If you use a recovery catalog, the RC_ARCHIVED_LOG view contains similar information.

V$ARCHIVE_DEST

Describes the current instance, all archive destinations, and the current value, mode, and status of these destinations.

V$ARCHIVE_PROCESSES

Displays information about the state of the various archive processes for an instance.

V$BACKUP_REDOLOG

Contains information about any backups of archived logs. If you use a recovery catalog, the
RC_BACKUP_REDOLOG contains similar information.

V$LOG

Displays all redo log groups for the database and indicates which need to be archived.

V$LOG_HISTORY

Contains log history information such as which logs have been archived and the SCN range for each archived log.

Using these tables we can verify that we are infact in ARCHIVELOG mode:

SQL> select log_mode from v$database;

LOG_MODE
------------
ARCHIVELOG

SQL> select DEST_NAME,STATUS,DESTINATION from V$ARCHIVE_DEST;

In Oracle 10.2 and above RMAN is supported by a number of new dynamic performance views including:

V$BACKUP_ARCHIVELOG_DETAILS

V$BACKUP_ARCHIVELOG_SUMMARY

V$BACKUP_CONTROLFILE_DETAILS

V$BACKUP_CONTROLFILE_SUMMARY

V$BACKUP_COPY_DETAILS

V$BACKUP_COPY_SUMMARY

V$BACKUP_SET_SUMMARY

V$BACKUP_SPFILE_DETAILS

V$BACKUP_SPFILE_SUMMARY
v$archived_log
