Backups on the physics of the standby database?

I use dataguard and standby a physical database. How to assign backups on the physics of the standby database to reduce the load on the primary database.

environment: windows

Database version: 11.2.0.1.0


What are the pro and cons on the allocation of jobs of RMAN backups for the physics of the standby database?

Hello;

The backup database is an identical copy of the primary database block.

Therefore, you just save one of the two (you can choose to only save the day before, however, if you want to remove the load on the primary). But if you are uncomfortable with the primary backup, it is not necessary for the safeguarding of the day before. (Since you can recreate the primary backup before).

The only important part, is that you use the RMAN catalog. Then only known RMAN, the two are identical and can use the same backup.

  • Destination different archivelog on the physics of the standby database

    Hello

    Can I set different archivelog destination for the physics of dual standby database? (Because of space issues) How can I do?

    For example, on the site main archivelogs reside in/u01/ORCL/archivelog and I want on phy. side Eve archive dest. under/u08/ORCL/archivelog.

    You can also give LOG_ARCHIVE_DEST_1 in file init Eve, so whenever you start sleep/auxiliary instance automatically done dest_1 refers to/u08/orcl (whereever you want).  So you can have destination archive anywhere but must have the appropriate permissions and location should be available.

    If you want to set a destination, then again you can use the "ALTERNATE" sort clause only when the primary location unavailable or unable to archive, and then, of course, he wrote in the other location you have specified a pfile.

  • failover and failback on the physics of the standby database.

    Hi all

    I use the EE 10.2.0.4.I oracle version have a configuration database and named prim and Everelief. I tried the method of failover. I liquidated low primary eve and convert to the new primary database.


    •Arretez repeat applies.
    Run the following SQL statement on the database waiting for target:
    SQL > ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
    Standing by applying all the data received to redo.
    In this we give indication to the standby database primary database is no more.

    SQL > ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH;
    Once the order of FINISH is completed, the mode of protection of the primary database is lowered to optimum performance, regardless of its original protection mode. This is done because the new primary can be activated with on a standby
    SQL > select protection_mode, protection_level from database v$
    Level of Protection for the protection Mode
    ——————– ——————–
    PERFORMANCE WITHOUT PROTECTION

    •Check that the standby database target is ready to become a primary database.

    Query column SWITCHOVER_STATUS of the view V$ DATABASE on the database waiting for target.
    •If the physical database ensures the main role.
    SQL > ALTER DATABASE COMMIT to THE MOVE to THE PRIMARY WITH the STOP of the SESSION;
    •Open the new primary database
    SQL > ALTER DATABASE OPEN;
    •At this point the level of protection is passed to Max Performance "Unprotected".
    Circuits the new primary database.

    Why do you think you have to check the free space into a storage ensures physical ?

  • Effects of the opening of a primary database in resetlogs on the standby database

    Hi all

    Operating system: Solaris

    DB: 11 gR 2

    Can anyone throw some light below the explanation is given in case of recovery through the OPEN RESETLOGS Statement oracle documentation

    If the database pending... Then... Perform these steps...
    Not asked to redo data beyond the new resetlogs SCN (after the start of the new branch of data recovery)Redo apply automatically takes the new branch of the roll forward.No manual intervention is required. The MRP automatically resynchronizes the database pending with the new branch of data recovery.

    Here is the link of the source:

    Manage a database of physical standby

    Kind regards

    Just to give a concrete example, I did a test on one of my VM boxes. The database currently shows:

    SQL > select sequence #, the journal of v status $;

    SEQUENCE # STATUS

    ---------- ----------------

    34 ACTIVE

    CURRENT 35

    ACTIVE 33

    While on the eve, I stopped the redo apply so the standby status is:

    SQL > select sequence #, used from v$ archived_log;

    SEQUENCE # APPLIED

    ---------- ---------

    YES 30

    31 YES

    32 YES

    33 NO.

    34 NO.

    The database ensures in a few newspapers behind the primary.

    On the primary, I moved the journal a few sequences, close, the bootable media and restored and recovered 37 sequence:

    RMAN > run

    2 > {}

    3 > restore database;

    4 > up 37 sequence;

    5 > restore database;

    6 > alter database open resetlogs;

    {7 >}

    During the open resetlogs operation, I have to tail the log of alerts on the standby database and the following output shown:

    RFS [11]: identified the type of database such as 'physical' standby: customer is ARCH pid 17192

    Archived journal 21 additional for each sequence 1 1 0xf3d44942 dest ID thread entry 1:

    So as you can see, the log shows the standby detects the resetlogs on the primary operation and the new branch of the roll forward and received the next archivelog with sequence 1.

    Audit on the eve, it shows the status following the archivelogs:

    SEQUENCE # APPLIED

    ---------- ---------

    31 YES

    32 YES

    33 NO.

    34 NO.

    35 NO.

    36 NO.

    37 NO.

    38 NO.

    1 NO.

    2 NO.

    And after restart the managed recovery process, it now shows:

    SEQUENCE # APPLIED

    ---------- ---------

    31 YES

    YES 30

    YES 19

    YES 33

    34 YES

    35 YES

    YES 36

    37 NO.

    38 NO.

    1 YES

    2 YES

    Archivelogs with sequence 37 and 38 were not implemented because of the CAMILLE on the main sequence until (but not including!) 37 and then properly applied the next archivelogs of the new branch of the roll forward, with sequence 1 and 2.

    Hello

    I turned the parameter standby_file_management to manual and since I created 3 primary data file, but they are not applied to the standby database.

    Hello

    Your problem is that the MRP standby automatically when a data file is added on the primary database. The reason would be that the parameter STANDBY_FILE_MANAGEMENT is set to MANUAL on the standby database.

    Please refer to this http://shivanandarao-oracle.com/2012/04/02/managed-recovery-process-mrp-terminates-on-standby-database-upon-adding-datafile-on-the-primary-database/

  • create the standby database using backup to restore

    Hello

    I'm creating a database ensuring 11g using a manual process of restoring a backup, but nothing helped. I can restore same failed backup.

    Here are the steps that I followed (courtesy of ORACLE-BASE) BASE-ORACLE Data Guard physical standby Setup in Oracle Database 11 g Release 2 -

    I'm confused about these steps:

    Copy the files from the primary to the standby server.

    Copy Standby controlfile to all locations.

    $ scp oracle@ol5-112-dga1:/tmp/db11g_stby.ctl /u01/app/oracle/oradata/DB11G/control01.ctl

    $ cp /u01/app/oracle/oradata/DB11G/control01.ctl /u01/app/oracle/fast_recovery_area/DB11G/control02.ctl

    My question is, for the 2nd copy, I have to stop the primary db? given that control01.ctl is updated all the time?

    Then I have not used the previous day ctl (db11g_stbg.ctl) and copy it into /u01/app/oracle/fast_recovery_area/DB11G/control02.ctl instead?

    Your help is very appreciated.

    Check "ORCL" your backup files will be present in this place.

  • GoldenGate to replicate physical of the standby database

    Use the extract parameter TRANLOGOPTIONS with the ARCHIVEDLOGONLY option. This

    force option extracts for ALO mode against a primary or logical standby

    database, as determined by the PRIMARY or STANDBY LOGIC value in the db_role

    column in the view v$ database. The default is to read newspapers online.

    TRANLOGOPTIONS with ARCHIVEDLOGONLY is not necessary if you use the ALO mode against a

    standby database physical, as determined by the PHYSICAL INTELLIGENCE value to the

    db_role column of v database $. Extract works automatically in ALO mode if it

    detects that the database is a physical standby.
