All rights reserved. | Common RMAN Configuration Settings Description Benefits Cons Archived log mode •Ability to recover to any point in time •Enables online backup operations Requires more storage space to accommodate both online redo and archived logs Block Change Tracking (BCT) Enables fast incremental backups. Without BCT, RMAN would have to scan the entire database to determine which blocks are changed during incremental backups. MINIMAL overhead on the database server Control file automatic backup •Database recoverability even if current control file, recovery catalog is inaccessible. •When in archived log mode, it is backed up automatically when database structural changes are updated. None ….Not Set By Default
- 6. Copyright © 2018, Oracle and/or its affiliates. All rights reserved. | Backup Retention Period • RMAN retention policy options applicable to disk AND tape: 1. Redundancy ( how many copies ; default is REDUNDANCY 1) 2. Recovery window ( for example, 7 days) • Long-term RMAN backups (outside of set retention policies) may be created with KEEP FOREVER or with an UNTIL clause • Issue RMAN DELETE OBSOLETE command regularly which – DISK : Deletes backup related files which are no longer needed – SBT : Updates media manager to which backup pieces are no longer needed to meet user-configured RMAN retention settings Recoverability
- 7. Copyright © 2018, Oracle and/or its affiliates. All rights reserved. | Recovery Catalog • By default, RMAN’s metadata stored in the control file • Having a separate Recovery catalog provides the following advantages: – Central RMAN metadata repository for one or more databases – Enables use of RMAN stored scripts instead of just command line – Enables creation of customized reports for all registered targets – Centralizes management and storage of multiple databases (mixed database versions and/or platforms) – Enables use of the KEEP FOREVER clause • No licensing fee for an RMAN catalog database • Common strategy is to co-locate the RMAN, OSB and EM catalogs on the same server RMAN’s Schema

All rights reserved. | RMAN Good to Know RMAN – Cont’d • RMAN command BACKUP RECOVERY AREA; – RMAN disk or sbt destination (D2D2T) – Optimized backup by default – Always a backup set backup type • RMAN backup encryption has license restrictions: – Directly to disk requires Oracle Advanced Security Option (ASO) – Directly to tape requires Oracle Secure Backup (OSB) – RMAN compression – BASIC is free – HIGH, MEDIUM, LOW require Advanced Compression Option (ACO)

- 11. Copyright © 2018, Oracle and/or its affiliates. All rights reserved. | What is Fast Recovery Area (FRA) ? • Unified near-line storage location for all recovery files and recovery related activities in an Oracle Database – Centralized location for control file copies, multiplexed online redo logs, archived logs, flashback logs, backups (image copy or backup set) – FRA can be defined as a directory, file system, or ASM disk group – A single recovery area can be shared by more than one database – Initialization parameters db_recovery_file_dest & db_recovery_file_dest_size • FRA may be on tier 2+ storage although not necessarily recommended – Slower storage could effect production database performance • Online redo logs, archived logs, Flashback logs and controlfile RMAN Managed Disk Storage Location NAME TYPE VALUE ------------------------------------ ----------- -------------------------- db_recovery_file_dest string /oradata/prod/fra db_recovery_file_dest_size big integer 500G
- 12. Copyright © 2018, Oracle and/or its affiliates. All rights reserved. | Fast Recovery Area Sizing • Archived logs - Estimate total size of all archived logs generated between successive backups on the busiest days x 2 (in case of unexpected redo spikes) • Flashback logs - Add in {Redo rate x Flashback retention target time x 2} • Incremental backups - Add in their estimated sizes • On-disk image copy - Add in size of the database minus size of temporary files – When using an incrementally updated backup strategy (incremental forever after initial full) • Full backup set backup(s) – When using a full / incremental backup strategy • Further details: – http://docs.oracle.com/cd/E16655_01/backup.121/e17630/rcmconfb.htm#BRADV8183 Exercise in Math – Depends on What You Want to Keep

Take the tablespace offline 2. Restore the Datafile from a backup 3. Recover the Datafile 4. Place the tablespace back online With FRA 1. Take the tablespace offline. 2. Switch to FRA Copy 3. Recover Datafile 4. Place the tablespace online.
