RMAN - catalog of recovery

Hi all

We have about 10-12 databases running - wanted to know your opinion on what is the advantage of using recovery catalog vs. just using controlfiles for rman backups?

Thanks in advance

Hi DBA115102,

These are the advantages by using the rman catalog:
- keep you metadata about backups in a same location record.
- you can save scripts in a repository
- you can make centralized (with your own scripts) backup reports
- you can restore a database to a previous incarnation

but also some constraints:
- you can get into trouble between versions. See compatibility matrix: [http://download.oracle.com/docs/cd/B28359_01/backup.111/b28273/compat003.htm]
- you must include the repository RMAN in a database upgrade strategy
- architecture is more complex (at least a new scheme, but a new database will be safer)
- you have more work with maintenance operations (intersection, resync, remove obsolete, register, unsubscribe...)

For my personal experience (I bet that's what you're really asking) using the catalogue is easier if you have a homogeneous environment.

    Do not back up the database using the same catalog of recovery recovery catalog of accommodation. You could just try it back up without a recovery catalog and to ensure that this database has an automatic backup of controlfile, for example.

    My question: why are the information stored in the database control file (Faure) target so that its stored in the recovery catalog?

    Hello

    By default, RMAN stored metadata in the file control, all the RMAN is first written to control the file and then catalog of recovery if leaves. For example, when rman creates a new backupset, you can view the information in the v$ backup_set and you can also view the same information of the recovery RC_BAKCUP_SET catalog views.
    So every change repository is stored in two places... Control file and optionally recovery_catalog

    The catalog of recovery of the RMAN Repository versions are stored in database tables and version control repository os file stored as files in with in the control file.

  • The Rman catalog must be registered?

    Hello experts,

    Don't you think that would be recorded in the database catalog Rman or not? If so could be in the same Rman catalog or in other different database?

    In the documentation of Rman something about this?

    My 11.2.0.3 Rman catalog database have a controlfile and default 15-day CONTROL_FILE_RECORD_KEEP_TIME.

    My media layer has a 90-day supply. So if I would to restore an older version of 15 days from the catalog in another machine I had to sign up former backups before games.

    Would be, this example above, a real possibility that I had to listen to extracts?

    Thank you and best regards.

    but do you think useful registry the Rman catalog database in the catalog itself? Or is nonsense? a why?

    Thanks and greetings

    Of course, it is absurd to register in the database catalog with himself.  The entire purpose of the catalog is to help the recovery.  So how the catalog database can help in recovery if the catalog database needs recovery.

  • Information on RMAN catalog database using and any catalog (controlfile)

    Hi all.

    I´d like some clarification on the subjects of RMAN RMAN usage with or without a recovery catalog (database / schema):

    (1) will be the database controfile target always store ALL changes made on RMAN? For example, configure changes persistent RMAN as a retention strategy, controfile autobackup, backup optimization and so forth, these will always record on the target database controlfile, even if we're connecting to RMAN with a recovery catalog?

    (2) what happens if we stop using the recovery catalog? I mean, if you don't use stored scripts and shot through the OS jobs or same EM control database, may continue to use then and do not connect more on the recovery catalog? It will be a problem? My target database stops?

    I will be the legacy a few databases to administer and they connects to a catalog of recovery of database / schema, it's good, but I want to set up my own backup and restore policies / procedures in a two-step process: (1) have each configuration of RMAN database on controlfile, Later (2) in view of the use of the recovery catalog to centralized databases and keep more disk backup and restore.

    Thanks in advance!

    (1) Yes, everything about the structure of data is stored in the controlfile. The location of the backup controlfile is also stored in the controlfile.

    The backup controlfile location is also stored in the catalog if you synchronize to it.

    (2) you can stop immediately using the catalog if you choose, and as long as you have a backup RMAN script file, you can always backup using this file.

    The catalog is used to store the location of the backupsets, and copy image. If you have any scripts to store, it can store these too. Really, it's all done catalog.

    You can back up and restore/recover without a catalog, as long as you know where all backups are retained.

    Hello

    The connection of the RMAN catalog remains inactive during the backup/restore process, once rman completes the task and try to activate the connection it gets error.

    What is expected as you said the rebooted server. If this happens because of the expiration time, we went with the parameter net expire_time to maintain the connection.

    A new catalog of recovery was created on linux servers (same name as the catalog of recovery on solaris zones).

    Since its new catalogue, then you will need to register your database in this catalogue and use this database schema name while making the connection to this rman catalog.

    Last time I would upgrade the catalog with 'Upgrade catalog' database to backup databases the new 11 GR 2.

    The upgrade looks good, but after this task, I have 21 invalid objects in the RMAN catalog and it was not possible to compile without error. And all the other which backups using the catalog fails the RMAN-06429.
    -> Package PL/SQL BAKRMAN. DBMS_RCVCAT Version 11.02.00.02 in the RCVCAT too recent database.
    I therefore return to the action.

    What is the right way to use the catalog rman with levels of different database?
    How can I use the catalog also for 11 GR 2 databases without any side effect on my other 11 GR 1 material databases?
    The rman catalog reside on a 11.1.0.7.0 database.

  • change a catalog of recovery to another

    Hi Experts,

    We have temporarily created a recovery database [cattemp] catlog and used this database to make RMAN bakcup during more than a week. Currently, we have created the permanent recovery catalog database [rcat11g].

    now, I have to cancel the registration of the existing and register with the database to catalog new recovery. If I unregiter will get the existing base of the catalog the repositary of file recovery deleted what is the correct procedure to migrate from one catlog to another.

    Please notify.

    (1) it will work installation where there is a mix of the target db versions. Are there special requirements to do this job or any restriction
    (2) say the catalog db is down, and the accident of my database target. I would still be able to restore my available target without the catalog db database?

    2 Yes: If you still have at least a current control file: restoration should be transparent. If you've lost all control files, then you must recover the backup file DBID and control location and know how to restore in a DRP as situation
    3. my humble opinion, it is more important to know how to restore without a catalog of recovery available to use the high availability features for the recovery catalog database.

    One of my new database received from group fixes 11.2.0.4.7.

    When I want to join this real my rman catalog database, I "PL/SQL package RMAN. DBMS_RCVCAT version 11.02.00.03 in the RCVCAT database is not current."

    I can easily do a "catalogue of upgrade", but is there an impact on my other databases running 11.2.0.4.0, which cannot receive the patches group before long.

    Thank you for your kind reply.

  • Firewall rules RMAN target database and RMAN catalog database

    Hi, we are on Oracle 11.2.0.4 and we just build a new environment, in which case the RMAN catalog is located on a seprate from the target database server. I'm trying to figure if the firewall between these two rules should be two-way, so that the target database and RMAN catalog database can ping each other. If bi-directional rules in place, so what's the reason for this? I understand that during RMAN backup entries are made in the RMAN catalog database, but do not know if the RMAN catalog database must always meet target db. Thank you!

    If you run the rman command on the target database server, it acts as a client to the catalog database server by connecting on sqlnet to the catalog database.

    If you run the rman command on the catalog database server, it's a sqlnet connection join the target database server.

    In both cases, rman is simply a client that connects to the two databases.

  • RMAN catalog by default for all databases of the value

    Hello

    I run a catalog RMAN 11 GR 1 material.

    I wonder if it is possible to change a default setting in the RMAN catalog so that he will inherit all new databases.

    For example, I would that all new data entered in the catalog for:

    BACKUP OPTIMIZATION

    REDUNDANCY 7 RETENTION STRATEGY

    Thank you

    No, the catalogue cannot "dictate" configurations for databases.  Each database maintains configuration in the controlfile and this can be changed that by rman connection (i.e. rman connection to the database target). The command SETS in rman is used to define a "permanent" for a database configuration parameter but must be issued individually for each database.
