  If no active transaction or data required by one of the session to restore, then it will be difficult to recover these transactions and your database data will be in a State of incoherence. As you only read only activity you can safely recover the database.

  Comment just undo tablespace and undomanagement parameters init.ora file and restart the database.

  Once the database is in place create undo tablespace and assigning like default undo tablespace tablesapce.

• RMAN backup on the database with data file with corrupted block

  Hi friends,

  I have a problem with a database of oracle 11g XE on windows server 2003, the database is in production, it is open, is operating normally.

  The database has no backup configured before, so I put the database archiving mode and tried to backup using rman utility, but it show me some errors.

  First of all, it showed me:

  ORA-19501: error in reading file... SYSAUX. DBF

  ORA-27070: async read/write failed

  OSD-04016: error queuing an asynchronous i/o request.

  And when I passed the dbv on the SYSAUX file utility. DBF showed the fatal error.

  So, I switched CHKDSK utility on windows to repair the disc of the error. After that, run utility dbv and he passed and showed me the corrupt on SYSAUX blocks. DBF

  Then, came to rman and ran:

  RMAN > validate the logical database checking;

  State of the file marked corrupt blocks examined empty blocks high YVERT

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

  Finally I try to rerun rman and he shows me the error:

  ORA-19566: exceeded the limit of 0 blocks corrupt file C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSAUX. DBF

  How can I do backup with rman? Maybe I can by pass the corrupt block?

  I'll be grateful for any help you can provide.

  
  

  =)
  

  It would be better if you try to find the reason of corruption and try to recover the corrupt blocks. A block corrupted in the backup would really not must use. But if you're ready to take backup, you can ask RMAN to ignore corrupt blocks and move forward.

  Use the pseudo-code for the backup

  Run {set maxcorrupte for the database to 10;

  backup tablespace sysaux ;}

• RMAN duplicate for standby the active database and the missing data files

  We have a car of 2 node ASM 11 GR 2 and 11.1 of database and a standby with ASM also. Our database is relatively low (300 GB)

  and in one recent event the day before was such a departure from the primary that we decided to "repopulate" the data using duplicate RMAN.

  I deleted the data files of the previous day and followed the Oracle documentation to duplicate a database. In the waiting

  I created a static listener and a pfile containing only the essential information (db_unique_name). I started the day before with nomount using the 'empty' pfile.

  I run RMAN, connected to the target and ancillary catalogues and run this command:

  run {
  allocate channel prmy1 type disk;
  allocate channel prmy2 type disk;
  allocate channel prmy3 type disk;
  allocate channel prmy4 type disk;
  allocate channel prmy5 type disk;
  allocate auxiliary channel stby1 type disk;
  duplicate target database for standby from active database nofilenamecheck;
  }
  

  RMAN duplication completed without errors, so I started the rescue database and got

  an error saying that datafile XXX is missing. I checked XXX datafile at the primary level

  and it is in a DISCONNECTED state. In the standby database the same data file is in the online state.

  So I think the problem is that during the duplication, RMAN (as documentation States) does not work

  Copy the files of data in offline mode, but the standby control file seem to think that these data files

  are online and should be present.

  Can someone please help me solve this problem? From my understanding, I could just copy the missing persons

  data files (there are many however) and in the standby go offline, but I don't think it's

  the right solution, edit this file for control of the standby? I would add another option

  in the RMAN script?

  Take the data file in offline mode on the site of the previous day.

  I don't think that two COPIES try to manage separately offline files.

• Recover data file / oracle database duplicate offers backup

  Hello.
  I have regular backups of all data files (copy of the image) and created by oracle archivelogs suggested backup.
  
  I want to recover the database to a specific day, and not to the last transaction, on the last day of backup was performed.
  So far I've always had the last transaction recovery with isn't an option because a large amount of data is missing, and I don't know what happened, I just know that that day there before (last image retrieved copy) is very well, but I'm unable to recover at this point. I used recover until sequence, up to the time, but I have always applied the newspaper.
  
  So my question is, can I restore the data file and retrieve it, I mean sync with the database without appling archivelogs to keep the data in this file, as it was the day of the last backup, or use this image copy to create another database to get the same things, or is there another way to get data as it was on the last day backup was taken.
  
  Any help is appreciated, the situation is very serious!

  Hi user12091398,

  Furthermore, it just ask, pourrais I try to use blockrecover to copy good image perhaps?

  With recovery of block, you will have to make a full recovery, it is of no use.

  Steps for cloning:
  -create an auxiliary environment (instance, space...) db_file_name_convert and log_file_name_convert parameters can be useful.
  -make elements of rman backup available on the host running the auxiliary.
  -set up tns to be able to access the target host of the auxiliary.
  -create and run a script in double
  Run {}
  define_db_name duplicate target database
  # up to "TO_DATE('2010-01-28:10:00:00','yyyy-mm-dd:hh24:mi:ss')".
  up to the time "TO_DATE('define_date','yyyy-mm-dd:hh24:mi:ss')".
  ;
  }

• Problems with duplicate DATA when the data file was added after the backup completes

  Hello
  
  I am facing a problem when running of duplicate database with the command of database duplicate RMAN on a 10 g database. If I have the duplication from a full backup that is missing a data file that has been added to the database after the full backup of preforms, I get the following error message:
  

  Starting restore at 10-10-2009 18:00:38
  
  released channel: t1
  released channel: t2
  RMAN-00571: ===========================================================
  RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
  RMAN-00571: ===========================================================
  RMAN-03002: failure of Duplicate Db command at 10/10/2009 18:00:39
  RMAN-03015: error occurred in stored script Memory Script
  RMAN-06026: some targets not found - aborting restore
  RMAN-06100: no channel to restore a backup or copy of datafile 43

  Redo log which was Pond at the time of the creation of 43 of the data file is also available in the backups. It seems that RMAN cannot use the log information archived redo to restore the content of the data file 43. I guess that because failure is already reported in the RESTORATION and not in the RECOVERY phase, so again the archived logs are not available yet. I get the same message even if I do another backup of the data file 43 (so a backup that is not in the same backupset as the backup to all the other data files).
  The script, the command duplicate product, I guess that RMAN reads the contents of the source database controlfile and trying to get a backup that contains all the data files to restore the database Assistant - if such a backup is not found, it fails.
  
  
  Of course, if I try to perform a restore/recovery of the source database, it works without problem:
  

  RMAN> restore database;
  
  Starting restore at 13.10.09
  using target database control file instead of recovery catalog
  allocated channel: ORA_DISK_1
  channel ORA_DISK_1: sid=156 devtype=DISK
  
  creating datafile fno=43 name=F:\ORA10\ORADATA\SOVDEV\SOMEDATAFILE01.DBF
  channel ORA_DISK_1: starting datafile backupset restore
  channel ORA_DISK_1: specifying datafile(s) to restore from backup set
  restoring datafile 00001 to F:\ORA10\ORADATA\SOVDEV\SYSTEM01.DBF
  .....

  The 43 data file is re-created and then redo is applied to the course.
  
  So, does anyone know if the duplicate database can use archived redo logs to recreate the contents of a data file, as does a normal restore/recovery? If this is the case, then it is necessary to perform a full backup before each duplicated if a data file has been added after such a backup database.
  
  Thanks in advance for any answers.
  
  Kind regards
  Swear

  Hi swear,.

  I got exactly the same problem during replication.
  Because we backup archive logs every 6 hours with rman, I added an additional block of running this script.
  run
  {
  backup incremental level 0
  format "% d_ % s_ %%t p_ bk_ '.
  filesperset 4
  database not saved;
  }

  (I also hit a bug in the catalogue which was resolved by patching up the dbs catalog 11.1.0.6, 11.1.0.7 for.)

  This will restrict the data not making file not part of any backup rman 6 hours while jumping for which there is already a backup of data files.

  Kind regards

• Roll forward standby database with the incremental backup, when a data file is deleted in primary education

  Hello

  I'm nologging operations + deleting some files in the primary and you want to roll forward the day before using the incremental backup Yvert.

  I do in particular, as the files are dropped?

  I got to meet ( Doc ID 1531031.1 ) which explains how to roll forward when a data file is added.

  If I follow the same steps, to make the move to restore the data file newly added, will it work in my case?

  Can someone please clarify?

  Thank you

  I was wondering if reocover noredo is performed before restored controlfile, oracle will apply the incremental backup error-free files, and in this case, what would be the status of the data file in the control file.

  Why do you consider to retrieve the day before first and then in the restaurant of the controlfile will lead to problems. Please read my first post on this thread - I had clearly mentioned that you would not face problems if you go with the method of deployment.

  Here is a demo for you with force logging is disabled. For the first time the day before resuming and restored then the controlfile ensures:

• Is it possible to recover a database with the copy of data files (cp), while the database has been opened?

  Hello

  We know we need to do a backup of an oracle database by using the appropriate tool, in most cases the rman. But we have in our society, a person who helps us with the backup of all the databases oracle we have. Thus, in addition to the rman backups, we do a copy (cp) with the open database of all files in oracle database, (without start backup) including of course spfile, controlfile, etc.. My question is: can recover us my database using this copied data files? or are we just wasting disk space on our backup environment?

  Kind regards
  Melo.

  We're doing a copy (cp) with the open database of all files in oracle database, (without start backup) including of course spfile, controlfile, etc..

  As EdStevens said, it's essentially a backup without value. When you copy files from a backup ' hot', there may be inconsistencies in the blocks of the file as transactions actively edit these blocks while the copy is made. Mechanism of Oracle backups hot managed by users is to put the database or tablespace in backup mode, copy the files, and then the end backup mode. Without this mechanism, the chances of being able to restore from this backup are very, very thin.

  My question is: can recover us my database using this copied data files?

  My question is... have you tested recovery? If the recovery has been piloted, then called the answer to this question. Please read the end of this blog post for more information:

  Blog of Peasland before necessary recovery database backups"

• put the offline data file when the database is in NOARCHIVELOG mode

  My question is when the database is in log mode Archive No. I am not able to take the database offline.

  When I tried in my computer I noticed set-aside.

  CASES1:

  SYS > alter database datafile 5 offline;

  ERROR at line 1;

  ORA-01145: offline immediately rejected at least media recovery enabled.

  case 2:

  SYS > alter database datafile 5 immediate offline;

  ERROR at line 1;

  ORA - 00933:SQL not correctly completed order

  CASE3:

  I tried the command drop alter database datafile offline 6; (in NOARCHIVELOG mode) and it is to show the same effect that alter database datafile offline 6; (in ARCHIVELOG mode).
  

  * In NOARCHIVELOG mode are we really drop the data file to use the offline data file? You please tell me the effect of the dropkeyword.

  Oracle protects you. Please review ARCHIVELOG and NOARCHIVELOG mode.

  When you take the database offline in NOARCHIVELOG mode:

  (1) the file is offline

  (2) the RCS in which you took the database offline will be is more to be in the online redo logs

  (3) at this point, you need to perform a media recovery to enable again the file online (ie. restore the database)

  So you can see why you shouldn't do that.

  The DROP Offline command does not actually remove the data file. It removes the control file file details and updates the offline data file. It can be used for purposes of recovery or when you actually plan on deleting data files.

• need to restore my database after losing a data file on my hard drive

  Hi all
  I installed oracle in my E: drive and create a tablespace (INDEX02) where it is placed the file data on the D: drive, I then installed linux on the c of the storage data file D: drive is lost, how can I recover the data? my database is in an archivemod
  
  Thanks for help

  the only solution you have:

  shutdown immediate ;
  startup mount ;
  ALTER DATABASE DATAFILE 'FD:\INDEX01.DBF' OFFLINE;
  alter database open ;
  

• After you rename the data file, cannot start database

  Oracle 11 g 2
  OEL 5 (ASM)
  Network infrastructure (cluster install) - no CARS yet
  
  Something interesting happened. Perhaps this question might be more suited to the "ASM" section, but that's.
  
  I gave a data in ASM file an alias with the following command (the ASM instance):
  

  SQL> alter diskgroup DATA add alias '+DATA/oradb/datafile/users01.dbf' for '+DATA/oradb/datafile/users.253.795630487';
  
  Diskgroup altered.

  Then, as mentioned in Note: 564993.1, we need to update the database as well with the new alias. However, when I went to the stopping and starting of the database, I received the following:
  

  SQL> shutdown immediate;
  Database closed.
  Database dismounted.
  ORACLE instance shut down.
  SQL> startup mount;
  ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

  It's strange. Nothing has changed except the alias being added to the data file. This is all before operation. That's happened?
  
  I think that it may have to do with the different ASMOPER, ASMADMIN, ASMDBA groups that have been installed as part of the installation of the grid Infrastructure. In addition, the listener is running out of the GI home.
  
  All my variables environment (e.g. ORACLE_SID, ORACLE_HOME, etc.) are defined.
  
  Any ideas?
  
  Thank you.

  Hello
  When you connect with tnsnames alias while the database is down the listner did not know the service, so you must start the database on the server database with sqlplus / as sysdba. After starting the registry of data base with the listener and your connection works again.
  Alternativ you can add a service to your listener.ora to connect with him while he is arrested, as long as you do not have it you must use local connect which means sqlplus / as sysdba.

• Backup of database data files

  Question: I have a primary and backup database. From now all the files data on both primary and standby time are in the same place, unfortunately, space can be added to my primary database. My question is, can you still maintain a database of relief if the physical location of the data files is not on the same mount point? that is to say:
  
  Primary data file: /u01/app/oracle/user_data01.dbf--> Standby datafile: /u03/app/oracle/user_data01.dbf
  
  I know I have to transform the management of the cancellation to the MANUAL file to make such a change, but can I turn back to AUTO after I finished to move this file? Thank you guys

  The customer has chosen to make a bad decision.

  You have two choices.

  1. compound it by agreeing to assume responsibility for their risk
  2. If you want to tell them that they must sign an agreement accepting full responsibility in case of failure.

  Choose wisely: they do not have.

  Personally, I refused to accompany customers who try to pass the risk of their bad decisions in my ability to sleep at night.
