Monitor the online backup progress in Oracle 11g (RMAN)

Hi,
is there  a simple way to see the progress of the online backp for oracle?
We are using oracle 11g and using RMAN td level-0 and level-1 backups in the SAP environment(SAP Netweaver 7.01)
Regards,
Rakesh

Thanks Siva!
I was looking for something like a script which tells me the running backup progress.
Like the following script which tells the status of RMAN backup (completed/failed):
col STATUS format a9
col hrs format 999.99
select
SESSION_KEY, INPUT_TYPE, STATUS,
to_char(START_TIME,'mm/dd/yy hh24:mi') start_time,
to_char(END_TIME,'mm/dd/yy hh24:mi')   end_time,
elapsed_seconds/3600                   hrs
from V$RMAN_BACKUP_JOB_DETAILS
order by session_key;
regards,
Rakesh

  • How to take a backup manually in oracle 11g express edition?

    how to take a backup manually in oracle 11g express edition? i want to take backup of a database and want to restore later on on a different computer .

    Stop database, and copy all files to another machine.That sounds to me to be the closest answer to the question posted. And perhaps the easiest solution.
    Install XE on the "another machine", shut it down. Shutdown the source database. Copy the datafiles to the new host. Startup your "new" database, it will be an exact clone of the original.
    To find out what files need to be copied, as system (or sysdba) run:
    select name from v$datafile;
    ... file1, file2 ...
    show parameter control
    ... control_files ... file1 ...
    alter database backup controlfile to trace [reset logs];
    show parameter diag;
    ... diagnostic_dest ... <drive:>|/diag_pathTo do a proper database clone its better to recreate the controlfile and reset the archive sequence number- leave out the controlfile copy part. In the diag_path location find the trace file under diag/rdbms/$ORACLE_SID/<db_name>/trace it should be the latest ora*.trc file.
    The trace file has the commands to recreate the controlfile, which includes the datafiles and putting the tempfile back in place. If the datafiles are in a different location, i.e. in Windows going to a different drive, or you want do put datafiles in a different folder location, the create controlfile statement is the easiest time to get the file directories right.
    If you add the "reset logs" qualifier (don't use the brackets!) you'll get just the reset logs version of the create controlfile statement, otherwise you'll get both NORESETLOGS and RESETLOGS versions of a create controlfile statement, run one or the other. Not both. Not the entire trace file, just the create controlfile, alter database open [reset logs], alter tablespace temp add tempfile ... bits. No recovery is needed for a database that is shutdown when datafiles get copied to a new location/host.

  • When is delete all obsolete backups triggered in Oracle 11g DB

    I have a query as to when delete all obsolete backups triggered in Oracle 11g DB. We changed the RMAN retention policy to 10 days from 14 days in our setup. Is it triggered manually by delete all obsolete from Availablity->Manage Current Backups in OEM or is it triggered automatically every time RMAN backup is done?
    I hope, my question is clear.
    Please revert with the reply to my query.

    First, I would never manage my backups in OEM.  When the crunch comes at 2:00 am, I don't want ever more moving parts to be involved in recovery.
    Second, the only thing approaching a "triggering" of deletion of backups is if your backups are in the FRA ... rman will, at the time of making a backup .. attempt to delete obsolete backups if necessary to free up space in the FRA.
    Other than that, oboslete backups are only deleted in response to a direct DELETE OBSOLETE command.  This command may optionally ( as shown by TigerDBA) include a run-time obsolesence rule, or it may depend on the standing configuration.
    Another thing to note is that backups are NOT marked as obsolete.  They are EVALUATED for obsolescence in response to a DELETE OBSOLETE or REPORT OBSOLETE command.
    And one final thing to not is that all recovery must begin with a full backup.  That would be the most recent full (or level 0 incremental) backup prior to the point in time to which you need to recover.  That means the most recent full (or level 0 incremental) backup will never be considered obsolete, regardless of how old it is.

    3) This will convert the capture model successfully in Oracle 11g but The naming of object like procedure, constraints ,views, indexes etc. Still exceed 30 character rule. I mean the object names are more the 30 character length.
    There should be way to fix the naming standards while migrating or converting the model ?

  • DB13: Execute Redo log backup of remote Oracle 11g database fails

    Dear Experts,
    First of all I have to state I am not very experienced in administrating (Oracle) databases, but I would like to ask you all the following:
    We run two SAP Systems with each their own database on the same host:
    1. SAP SRM ABAP system on Oracle 11g
    2. SAP NetWeaver WebAS Java (Portal) on Oracle 11g
    We would like to schedule backups of the Java database in transaction code DB13 on the SRM ABAP system.
    Actions already taken:
    - We have maintained the proper database connection to the Java database and have set file system permissions correctly (according SAP Note 102570). Connection in transaction DB02 is fine and stats are showing for both databases.
    - We have maintained enviroment settings for <SID>_ORACLE_HOME and <SID>_SAPDATA_HOME and for the shell (csh).
    - Destination SAPXPG_DBDEST_<host> is maintained in SM59.
    When we schedule a Redo log backup of Java System in DB13 and execute immediately, we receive the following error:
    Process died due to signal 11
    SXPG_COMMAND_EXECUTE mislukt voor BRARCHIVE - oorzaak: unknown
    Any tips?
    Thanks in advance & Best regards,
    Jan Laros

    Hi Eduardo,
    Thank you for your reply.. Today I am at another customer, so I can not check it. But is seems to me that the BRTOOLS are up-to-date as we installed the system fresh and imported the Support Package and kernel updates right afterwards.
    I will check which BRTOOLS are used tonight, anyway.
    Best regards,
    Jan

  • Can we restore oracle 11g RMAN backups to 10g server

    Hi,
    I have RMAN backups (full backup)of oracle 11g database. My server was suddenly crashed due to hardware failure.
    We have another Oracle 10g server. Is it possible to restore RMAN backups of 11g database to Oracle 10g server???
    Thanks

    I don't have 11g server ready with me. The other server running oracle 10g and I dont have rights to install oracle 11g on the 10g server. So I can not test the RESTORE/RECOVER commands.
    If anyone had experience in the past, please let me know whether we can RESTORE RMAN backups of 11g database to oracle 10g server...
    Thanks

  • Are backup notifications in Oracle 11g DB covered in notification rules

    I had a query whether a notification for backup job completion in Oracle 11g database is covered in the notification rules section available in enterprise manager. I could not find any other way of sending notification from EM so was wondering if the notification for backup job completion is covered in the notification rules section.
    Please revert with the reply to my query.
    Regards

    My understanding from your answer is as follows:-
    1) The email addresses have to be entered in Preferences->General. Say I enter [email protected] & [email protected]
    2) In Preferences->Notification Schedule, we can specify either of [email protected] or [email protected] and we cannot specify [email protected] as it is not included in Preferences->General?
    I have tried to put the observations as examples, request you to please check and revert with examples if my understanding is not correct.

  • How do you re-install your catalog from the online backup service?

    I have a new computer, but I backed up my photoshop files onto the online service, and paid for that.  Now I have gotten my photos back, but am unable to find the catalog.  Does anyone know how to find the catalog in the backup service files?

    From online services , i hope you mean Photoshop.com services.
    When you upload the file in photoshop.com then the ablums get uploaded.
    To get the catalog as the old one
    Create a new catalog
    Go to the Backup synchpreferences (edit>preferences>Backup/Synch)
    Mark  the albums you want to download.
    You can set the path of the download as well from the setting named as 'Folder For downloaded files :'

  • Backup and Redundancy Oracle 11g

    Hi,
    1. If we set the redundancy to 2, does it mean 2 level 0 backups taken at 2 different points in time one after another or does it mean 2 copies of the same level0 backup?
    2. What is the effect of redundancy 2 on incremental backups? Are they also going to be 2 copies?
    Thanks & Regards,

    Vijay.Cherukuri wrote:
    Hi,
    Have you read the above link ?
    Assume a different case in which REDUNDANCY is 1. You run a level 0 database backup at noon Monday,
    a level 1 cumulative backup at noon on Tuesday and Wednesday, and a level 0 backup at noon on Thursday.
    Immediately after each daily backup you run a DELETE OBSOLETE. The Wednesday DELETE command does not remove
    the Tuesday level 1 backup because this backup is not redundant: the Tuesday level 1 backup could be used to recover
    the Monday level 0 backup to a time between noon on Tuesday and noon on Wednesday. However,
    the DELETE command on Thursday removes the previous level 0 and level 1 backups.
    Also please see : http://web.njit.edu/info/oracle/DOC/backup.102/b14191/rcmconc1007.htm
    As far i know RMAN does not delete backups if they are needed for recovery although they are obsolete (crossed retention policy )Not until you issue DELETE OBSOLETE.
    Please note that backups are not marked obsolete. They are evaluated for obsolescence when a command that references obsolescence (DELETE ... or REPORT ...) is issued. You can change your retention policy all you want, but until you actually DELETE OBSOLETE, nothing happens to those backups. Then they will be deleted (or not) as per the retention policy that is in effect at the time of the DELETE OBSOLETE command.
    That said, it is my understanding that if you keep your backups in the FRA, oracle will automatically delete obsolete backups if needed to free up space for newer backups. I've not personally investigated this so could be wrong. If this is the case, I would imaging that oracle still would not be deleting a backup as soon as it becomes obsolete, as that would require constant re-evaluation, but rather when it determines that it needs to find some space for a new backup.

  • Online backup and the Redolog mechanism

    Hello,
    During a backup I understand that the redolog mechanism changes, so that when a block is changed for the first time after the backup commences, it's entire content is copied to the redolog files, rather than just the change vector.
    My question is, does this happen even when the oracle block size is the same as the operating system block size?
    My understanding is that the change in redolog mechanism is because a single oracle block can be made up multiple operating system blocks, so that within an oracle block a change can be done to a few blocks, then a read by the online backup, so that the oracle block read by the backup is inconsistent.
    But if the oracle block size was the same as the operating system block size, each change would be atomic, so the problem of having inconsistent oracle blocks would not arise. So the change in redolog mechanism would no longer be necessary. Does the redolog mechanism change anyway?
    Kind regards,
    Peter

    Hi Peter,
    I will try to make the issue more clear eventhough so much useful has been written and said in this thread !!
    During Online Backup the tablespaces enter the backup mode this has following effects:
    1) A checkpoint on TS level is triggered before the backup of this TS starts and DBWR writes all corresponding dirty blocks of this TS to data files.
    2) The SCN corresponding to TS Checkpoint remains Frozen in the headrers of all TS files until the end of backup mode.
    3) Every change in this TS is logged in the redolog on data block level instead of data record level ; not only the redo info for a modified record is written into the redolg but the whole 8 KB block containing this record ( immaterial whether OS block size is 8 KB or not). The reason for this granual logging is the possibility that
    CPIO or DD may copy an oracle block to the backup medium in smaller units than 8 KB while the block is being changed by DBWR which can lead to inconsistencies whithin such a block.
    Now When the backup later used for restoring the TS, all blocks written to the redo log during the backup mode overwrite therir "suspicious"versions saved directly in the backup of the data files.
    Hope this useful
    Regards

  • Oracle Restore from Online backup without any archive logs

    Hi,
    May be a dumb question. If I have a good online backup (say it took 2 hours to do that. And there is database activity while backup is going on), and lost all the archive logs happened after the online backup, is it possible at all to do the restore using that backup? complete or incomplete? and bring back the database to normal operation mode? Some details on this.
    Thanks.

    Let us see the reasoning behind this.
    Database:WORLDDB
    WORLDDB configuration:-
    TBSP_WDB
    ->TBSP_WDB_01.dbf
    ->TBSP_WDB_02.dbf
    SYSTEM
    ->SYSTEM.dbf
    USERS
    and so on for the tablespaces.
    CASE 1:-
    User managed backup.
    You issue
    ALTER TABLESPACE TBSP_WDB BEGIN BACKUP;
    DB keeps working all transactions are recorded in the redo stream, the scn information is not updated in the file header.
    Also note that the other tablespaces were been continuously worked on hence their scn numbers are a moving target.
    http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96572/osbackups.htm#10012
    So if you begin tablespace TBSP_WDB backup at time t1 and by the time you are done with your backups you are at time t2, you will need all of the archive log's between time t1 and t2.
    CASE 2:-
    If we do with rman, rman takes care of the file header update information and goes on its merry way, those details are hidden from the end user. If one of the tablespace is fractured, updated while backups are going on , rman knows about it and will re-read the affected blocks in question.
    My thinking would be that you might need archive logs, unless it is a cold backup, with switch logfiles in between.
    If you do hot backups you need archivelogs is my thought. The number of archivelogs required will be decreased considerably through rman.
    http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmconc1.htm#458821
    Summary:-
    Either way archivelogs are needed.
