backup rman Exadata with zfs

Our company has recently decided to start backup rman ZFS instead of regular tape backup.

I would like to know what is the right measures to check if ITS configured right device of ZFS, the implementation of rman backups, etc.

I'd appreciate someone here can point me to the right document.  I read ZFS Q and A and backup using ZFS best practices. All very unclear and seems none of them provide a digital step step.

I wonder if Oracle provides an instruction step by step for the DBA.

9233598-

Q documents & you examined include the "Oracle ZFS storage pool: FAQ: Exadata RMAN backup with Oracle ZFS Storage Appliance (Doc ID 1354980.1)" Note? This note has a lot of information and is updated regularly and includes information about configuring ZFS and RMAN backups to the device of ZFS.

Some useful books of whites, an I have used in the past and has been updated again last year: Oracle Exadata with the Sun ZFS Storage Appliance protection: best practices in Configuration and backup and recovery Performance and best practices using Sun ZFS Storage Appliance with Oracle Exadata Database Machine

These documents will in many details - including providing examples of scripts.

HTH.

Thank you

  • backup rman design database with phsical ensures

    Hello

    12 c database, after physical expectation is created, I need backup rman configuration,

    The goal is: a) backup of database b) remove archivelogs that have been backed up, free up space FRA.

    Design as below:

    1:

    in RMAN (primary and standby):
    RMAN >
    Configure controlfile autobackup on;
    set the type of backup device type disk compressed backupset;
    CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;


    2: primary school:
    RMAN > CONFIGURE RETENTION POLICY to the 5 DAY RECOVERY WINDOW;

    3: in priamry, turn on track changes to block

    4: primary, implemented since rman level 0 (full backup) on Sunday.

    5: in the primary, the installation program rman level 1 backup from Monday to Saturday.

    6: primary, set up since rman "save archive backup delete them all obsolete" every hour;

    questions here:

    1. as in step 5, for the protection of the o and delete archivelog, the script using:

    Run {}
    allocate channel d1 type disk;
    SQL 'alter system archive log current';
    overlap archivelog all;
    backup AS COMPRESSED BACKUPSET archivelog all delete them all input;
    output channel d1;
    }

    I wonder if ' archivelog all delete all entries "will delete archivelog which was not taken on the eve of the database and broken standby database

    (hanging and out-of-sync with primary)... it is a concern, is that possible?

    2. If the primary database crashed, failover to standby mode, then restore/recovery primary, switch back to the primary, this design is just? If you have any good suggestions, please let me know.

    (to put it simply, I don't want to full/incremental backup to install standby, primary server CPU is good enough)

    Thank you very much!

  • case of disaster with backup rman and archivelogs

    Salvation;

    When the disk failure comes and drop everything on disks, if we have a cold backup and logs archiving ONLY after a cold backup up to disk failure, we can restore files (datafiles, controlfile and everything) and apply to these cold backup archive logs and make the database updated up to the failure of disks.

    I had this case in real life, and it works.


    but

    What happens if you don't have backup rman online that was taken before the failure of disk instead of cold backup and archive logs that was created after the backup online up to the failure of the drive.


    We can restore the online of rman backup files, but can we apply archive logs to these restored files to update the database to the disk failure?



    Best regards

    Use the SET clause UNTIL - for example the VALUE up to TIME - before running the command RECOVER the DATABASE.

    See http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsubcl019.htm#i1000331

    and example 4-38 on the same page.

  • The user managed based backup Rman backup cold cold vs

    Hi all

    I just want to know the advantages and disadvantages for backup managed user cold and cold backup Rman.

    What is the best cold backup?

    Some some can help me?

    Thank you

    Cedric Joshi

    Hello

    Both are good only... If you took the clod backup (managed by the user), you can also do with RMAN catalog.

    I feel clod RMAN backup is good.

    Reason:

    ======

    ++ with RMAN you can avoid used used block, you can only backup used blocks

    ++ RMAN has its own compression algorithm

    ++ We also have the ability to assign multiple channels to parallelize the backup

  • Help remove backups rman (delete the repository)

    Hi all.

    I will soon be administering a few databases Oracle (11g Rel2). Currently these DBs area in log mode archive with a backup rman in place policy.


    I don't like this policy and you want to use my own, incremental backups from updadateable, so this is the plan I have in mind.


    (1) disable mode archive.


    (2) a clean shutdown and take a backup to cold.


    (3) since after you disable archiving, backups RMAN ALL will be unusable, I want to remove them (including newspapers archive and backup sets).


    (4) after the correct deletion, set up some persistent RMAN settings, such as retention policy, controlfile autobackup and optimization.


    (5) turn on archiving


    (6) to set up the new policy based backups backup incremental updateable with duplex location for archiving logs.


    Help is requested on the best way to clean all the backups (3).


    I can manually delete the backups and do overlap, but according to the Oracle Documentation "Delete backup" will be delete all backups for data recorded in the RMAN Repository.


    So which is the best way easier and faster? Will delete backup include the archive logs?


    Thanks in advance. Luis!

    Can I still use them?

    I would say it is "the wrong answer to evil. When you disable log mode archive, you can only back up the database when it is stopped and only to restore and recover the database until the last stop.

    Looking at your plan, I wonder what you are trying to accomplish first log mode archive disabling and then enabling archive mode log again. Why do you think that this is necessary and what you're trying to accomplish.

    You need not disable and enable log mode archive in order to eliminate the obsolete achivelogs.

    If you are not satisfied with the retention policy, simply change it. All backups that are outside your retention policy will be considered as obsolete and you can remove them using RMAN delete obsolete, which will remove all files as well as the appropriate data backup from the RMAN Repository.

    For example you can archivelog delete all the entries backup and then delete the backupset or remove them at the OS level, do overlap and then use delete noprompt expired archivelog all.

    The retention policy applies to backup and archivelogs. However, you can have a separate archivelog deletion policy that applies to archivelogs.

  • Do not lock - automate the deletion of backups RMAN old day after a success

    Hi all

    Admin: Do not lock this thread. I moved here the database instance based on the suggestion of another Member, and the question to this forum. If you want to lock a thread, lock one in the forum of the database, not this one.

    I am looking for a way to automate the deletion of backups RMAN old days only after the occurrence of a success. At the present time, I have daily backups of L0 via crontab, and I need to create a script that can tell if a successful backup is done, then delete the old L0 if it has. Any suggestions on how to start? I'm stuck in code to see if a successful backup has been performed.

    A backup is completed when the backup command is complete.

    You have two 'blocks execution' in your rman script.

    Put the DELETE OBSOLETE between the end of the last execution block and EXIT:

    OUTPUT CHANNEL fs1b;
    OUTPUT CHANNEL fs2b;
    OUTPUT CHANNEL fs3b;
    CHANNEL fs4b;
    CHANNEL fs5b;
    CHANNEL fs6b;
    CHANNEL fs7b;
    CHANNEL fs8b;

    }

    remove the backup noprompt obsolete;
    "exit";

    You also want to do some other household:

    cross-checking of backup;

    delete expired backup noprompt.

    overlap archivelog all;

    delete noprompt expired archivelog all;

  • BACKUPS RMAN DELETE

    Hi all

    We backup 11203-db with rman (11203). One of our databases has been removed (by design). Now we have backups remains in the rman catalog I see when you set the appropriate dbid. As the PB in question no longer exists I cannot connect to the ddb and therefore cannot delete these backups.

    Is it possible to delete the catalog rman backups.

    Any help appreciated.

    • I will be very thank full if any brother help me in this respect and allow me to get it backed up on the server where the rman repository.

    An RMAN backup is always on the database server.  Server process run attached to the database and these create the backupsets.  Thus, they are created on filesystems which are 'local' on the database server.

    You can NFS mount a file system of your rman client server to the database server and then run the RMAN backup as if the file system is 'local' on the database server.

  • Restoring a backup RMAN to a new instance of the database

    Hi guys,.

    I have a problem with restoring a backup RMAN I have with me a new instance of the database. I have with me are:

    1. backup of the SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_. BKP)

    2. backup of the control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_. BKP)

    3. the full backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_. BKP)

    I received these files to a client environment and I need to restore these to a new instance of the database on a local computer. I gave an attempt as follows (in Oracle 10 g):

    1, creates a new instance of the (Test75) database using the Oracle Database Configuration Assistant

    2 SET ORACLE_SID = Test75

    3 connection to this instance with RMAN

    4 tried to restore the SPFILE from the BKP file received.


    I make mistakes and cannot continue. I don't know if I will carry out the correct steps. Please help me telling me how I should achieve this goal.


    Thank you.

    1. backup of the SPFile. (O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_. BKP)

    2 backup of control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_. BKP)

    The first backuppiece resembles a ControlFile and the other looks like a SPFILE'

    > I get error and cannot continue

    What is the error?  (I assume that you have tried to restore the O1_MF_NNSNF_SPFILE_BU_92DVGW9H_ SPFILE. BKP

    Note that you must also SET the DBID before restoring the controlfile

    It contained a real data file? Or was it a backup controlfile? A backup controlfile may be outdated if another backup controlfile does not capture the same information it contains.

  • Backup RMAN ASM filesystem

    Hi all

    I have an rman backup (datafile and controlfile) who got caught in an instance of the DSO (not a RAC) ORACLE 11.2.0.2 on a server Linux, now I want to restore the backup into a new database under windows/Linux OS with storage system (single instance RDBMS) General files instead of ASM.

    Is this possible?

    I can restrore an rman backup ASM in a mechanisim of storage of file in a new server system?

    Please clarify my question.

    Thanks in advance...

    Hi Levi,

    Thank you for your invaluable script and the blog.

    can you tell me about this query:

    I have an RMAN backup, drawn from the ASM and the backup is the database and controlf backup file that contains the data files and controlfiles.
    Now I need to restore this on my system and here I only use ASM or archive log, I use only one instance in any database log mode archive.

    I restored the backup controfile RMAN control file.
    Before you restore the control file, I checked the pfile orginal of the backup of database with parameters such as
    "db_create_file_dest."
    "db_create_online_log_dest,"
    "db_recovery_file_dest_size."
    "db_recovery_dest,"
    'log_archive_dest '.

    Since I'm not gng to create a database in any mode of newspaper archive, I do not use any of the above parameters and created a database.

    Now my question is:
    If I restore the database and the data file get restored and after rename all the log files, the database will be open.

    I want to know if this is good or bad, and the database will work as he previously worked. Or need to create the db_file_recovery and also other settings for this database.

    All parameter:
    All these settings should reflect your current environment, any reference to the old environment must be changed.

    All file system used:
    No matter what you use the file (datafile/redolog/controlfile/archivelog/backuppiece) file system are created on binary Format that depend only on platform. Thus, the file binary (for example datafile) have same format and content on the device gross, ASM, ext3, ext2 and so on. Thus, for the database, it is just a place where the files are stored, but the file are the same. ASM has a different architecture of the regular file system and must be managed differently (IE with RMAN).

    On the database:
    Given that your database files are the same even different file system using what you need is rename your files from data/redofiles on controlfile during the restoration, the redo files will be recreated.
    So, no matter if your database are noarchivelog or archivelog, in the same way you do a restore on ASM is the same way to restore the regular file system. (just rename the database during restore controlfile)

    On blog post 'How to migrate all files on ASM to no - ASM (Unix/Linux)' is suddenly of system files to another folder. But you can change the script used for restore purposes;

    ## set newname tell to RMAN where file will be restored and keep this files location on memory buffer
    RMAN> set newname for datafile 1 to ;
    
    ### swich get list of files from memory buffer (rman) and rename on controlfile the files already restored.
    RMAN>switch datafile/tempfile all ;
    

    With mounted database, use this script below:

    I just commented on three lines that are not necessary in your case.

    SET serveroutput ON;
    DECLARE
      vcount  NUMBER:=0;
      vfname VARCHAR2(1024);
      CURSOR df
      IS

        FROM v$datafile;
      CURSOR tp
      IS
        SELECT file#,
          rtrim(REPLACE(name,'+DG_DATA/drop/tempfile/','/u01/app/oracle/oradata/drop/'),'.0123456789') AS name
        FROM v$tempfile;
    BEGIN

      FOR dfrec IN df
      LOOP
        IF dfrec.name  != vfname THEN
          vcount      :=1;
          vfname     := dfrec.name;
        ELSE
          vcount := vcount+1;
          vfname:= dfrec.name;
        END IF;
      --  dbms_output.put_line('backup as copy datafile ' || dfrec.file# ||' format  "'||dfrec.name ||vcount||'.dbf";');  ### commented
      END LOOP;
      dbms_output.put_line('run');
      dbms_output.put_line('{');
      FOR dfrec IN df
      LOOP
        IF dfrec.name  != vfname THEN
          vcount      :=1;
          vfname     := dfrec.name;
        ELSE
          vcount := vcount+1;
          vfname:= dfrec.name;
        END IF;
        dbms_output.put_line('set newname for datafile ' || dfrec.file# ||'  to  '''||dfrec.name ||vcount||'.dbf'' ;');
      END LOOP;
      FOR tprec IN tp
      LOOP
        IF tprec.name  !=  vfname THEN
          vcount      :=1;
          vfname     := tprec.name;
        ELSE
          vcount := vcount+1;
          vfname:= tprec.name;
        END IF;
        dbms_output.put_line('set newname for tempfile ' || tprec.file# ||'  to  '''||tprec.name ||vcount||'.dbf'' ;');
        END LOOP;
          dbms_output.put_line('restore database;');
        dbms_output.put_line('switch tempfile all;');
        dbms_output.put_line('switch datafile all;');
        dbms_output.put_line('recover database;');
        dbms_output.put_line('}');
     ---   dbms_output.put_line('alter database open;');  ### comented because you need rename your redologs on controlfile before open database
        dbms_output.put_line('exit');
    END;
    /
    

    After the restoration, you must rename your redologs on controlfile to old location to the new location:

    for example

    ##  use this query to get current location of redolog
    SQL>  select group#,member from v$logfile order by 1;
    
    ## and change from  to 
    
    SQL > ALTER DATABASE
      RENAME FILE '+DG_TSM_DATA/tsm/onlinelog/group_3.263.720532229'
               TO  '/u01/app/oracle/oradata/logs/log3a.rdo'  
    

    When you change all the redolog on question below controlfile command:

    SQL> alter database open resetlogs;
    

    PS: Always follow the database in real time using the alert log database file.

  • disadvantages of backup RMAN of DATAGUARD

    Hello

    What are the drawbacks, backup RMAN to the DG on production?


    is it appropriate to the RMAN BACKUP in DG?


    Thanks in advance!

    If you manually stop, then you will offset in standby mode. Here, you can not reach to take backup to standby with up-to-date data.
    or
    You can try that option as well, to enable archive transport & stop MRP fool the most recent data will not apply, then you can go for an archive backup. Apart from that I do not think that this option.

  • Backup RMAN HRTO

    Oracle 11.2.0.2

    Question: Via TSM I need to copy a backup rman since a TSM server to the disk.

    I have rman backups who have written on tape SBT (TSM server). I can get the handle with the backup from the list, but how to find the path where it is written. Looking at the tdpo.opt file has a value for TDPO_FS, which is a virtual drive. I can't use backup because rman backup set which works only from disk to tape and NO tape on the disc. So I have to try to get this backupset through TSM commands.

    Any help would be appreciated!

    If you want to copy the TSM backups on disk, you can simulate a scenario to "restore to a new host. The TSM API knows where to find the tape backup.

    http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmadvre.htm#i1007814

    Otherwise, you have tom consult TSM staff, I am sure that 'somewhere' in the TSM environment that real places are stored. But who does not directly to RMAN/Oracle.

  • Backup and recovery with EXPDP and IMPDP

    Hello

    I have a problem of beginner!

    My environment is 10.2.0.4 & 11.2.0.2.

    I wish
    to backup a small database with EXPDP (FULL=Y)
    and to recover it with IMPDP(FULL=Y). ( *I don't want to use RMAN in this case*)
    My question:
    + what have I more to backup ( e.g. Passwordfile, control files, init.ora..) to be able to recover  
      successfully with IMPDP?
    + what are the steps to recover with IMPDP?
    I tried looking for a Howto in INTERNET, but in vain so far!

    Can any expert answer me? or show me a place to get a good HOWTO?

    Thanks and greetings

    So that's a little different situation from the initial, general issue.

    This situation Yes, create a new instance when the user that contains the data catalog rman since your last export import. The rman catalog is usually low volume enough this import will have no problem (we will assume that the export has not held while all backups rman-ducts were running).

    We know that your environment already relies on rman, since it is the rman catalog you save, you must familiarize yourself with rman still. Set up rman backup and restore for your sounds of database catalog rman as the perfect learning exercise that you improve on the procedures of your predecessor.
