  Hello
  
  cold backup of rman includes onlinde redologs?
  
  So that at the time of the recovery when I restore the database the redologs online also restored at this point?
  
  Please, please add your suggestions. I read in 10g database in condition to mount everything taking the backup RMAN as cold as the oracle process overall are down we cannot copy the redologs online.
  Am I correct, otherwise please someone answer me why the redologs online are not copied.
  
  Thanks in advance

  A cold backup (i.e., MOUNT but not given) to RMAN does not backup online redo logs.

  If you restore this backup you will need OPEN RESETLOGS to recreate the online redo logs to the target.

  PS: Oracle Documentation prefers to call an RMAN backup backs "Cohérent" when the database is mounted but the State is not OPEN. "Cold Backup" is today used for the non-RMAN methods.

  You connect through an earpiece.
  The listener becomes aware of the database when you turn it off.

  You run RMAN from the same server as the database? You need not connect through an earpiece.

• Cold backup RMAN

  Basically I ask this question for a problem surrounding in another thread, but here go us:

  Suppose we take a COLD backup. I know, not something directly related with RMAN, but further action is:

  This guy says: I take a backup to cold, I copy the files to another server, on which he has made the necessary in order to start this database.

  But then, since the backup and the time of the action above, time is up.

  So, there are archived redologs... because the database is in archivelog mode.

  And he wants to do what is obvious: use these Redos archived, to update the database at a later stage in time.

  To be clear; the Oder archived are created by the source database. The target database has been copied and started, nothing else.

  If the backup is a backup hot, without issue. But because the backup is cold, it is not possible, right?

  My idea is that he must also take a hot backup, in addition.

  I asked already, and despite the execution of the database in archivelog mode, the backup must be taken cold, backup mode for some reason. It is probably the old method, who they now want to just add redolog recovery, but without change from cold to hot.

  At some point, RMAN must be running, of course.

  I guess that RMAN is used for the entire operation, not "at some point" (I see no reason not to).

  The cold food at the start is to make a clone. THEN, the question is asked, but can we also restore to a point more recent in time?

  Yes, you can recover the "clone" until a more recent point in time as long as you do not OPEN it, and you have all necessary archivelogs. The sequence:

  1 startup nomount

  2 restore controlfile

  3. change the editing of the database

  4 restore your cold backup (do not open the database)

  5. If necessary, catalogue archivelog backups

  6 back to the desired point in time

  7. alter database open resetlogs.

  But I repeat, why did you stop your databases, if that is not necessary? (of course I think of my dozens of databases 24 x 7).

• Cold backup RMAN script

  DB version: 10.2.0.4
  
  Can't you find something wrong in the below mentioned the cold backup RMAN script? Improvements, corrections?
  

  {
  shutdown immediate;
  startup mount;
  backup database including current controlfile tag='full_bkp';
  startup;
  crosscheck backup;
  delete noprompt obsolete device type disk;
  resync catalog;
  }

  Should work, but you can include more 'archivelog' in the backup statement in the case where your database is running in archivelog mode. It's also a good idea to make a backup of the trace of the controlfile using "sql" controlfile alter backup database to TRACE";"

• RAC RAC CLONE OF RMAN cold backup

  Hi all
  
  I need your help in my Oracle RAC 11.2.0.2 to remote host environment cloning. Here's the disc structure
  
  DGVOT (disc ASM holding OCR and voting disk group)
  DGDATA (disk group ASM containing data files)
  DGFRA (disk group ASM files for fast recovery)
  
  Remote host is on a different location so cannot use duplicate RMAN with auxiliary channel.
  Have the luxury of downtime so I wanted to take coherent RMAN (Cold Backup)
  
  SAME structure of the disc is available on remote hosts.
  
  11.2.0.2 CLusterware (IG) over the oracle binaries are already installed.
  
  Can any body tell me the steps to
  (1) how to take cold backup on the disk so that I can tar and copy to the remote host
  (2) clone of the database on the remote host
  (3) how do I add the listener for the database and other resources of this databasee clusterware.
  
  in fact, it's my first clone CARS, so I'm well aware of the steps in detail.
  
  
  I went though a lot of notes metalink but nobody fits my needs. your tips will help me a lot
  
  Kind regards

  Hello

  (1) how to take cold backup on disk so that I can tar and copy to the remote host.

  Use Rman cold backup

  At the stage of the mountain run
  RMAN > backup database archivelog format '%U /dbp ";
  RMAN > backup controlfile current format "%U /ctl";

  Copy these to the remote host backup sets

  (2) clone of the database on the remote host

  Create groups of similar ASM disk as source
  create pfile/spifile, starting in nomount mode instance
  backup set from catalog

  RMAN > catalogue start with "";

  Restore controlfile

  RMAN > restore controlfile;

  RMAN > restore database;

  RMAN > restore database;

  On the success of the recovery

  RMAN > sql 'alter database open;

  (3) how do I add the listener for the database and other resources of this databasee clusterware.

• How Controlfile SNA remain synchronized after moving the database with the cold backup

  Hello DBAs,

  I doubt that:

  Every time you pass a cold backup database. We create a new controlfile with new locations of data/redologs etc.

  And then we execute "create controlfile reuse...". noresetlogs...; "to create the controlfile.

  After that, we will open the database as > > alter database open;

  Now the question is:

  We are able to open the database without clause "resetlogs.

  Here, we create a new controlfile so SNA to controlfile will not be synchronized with the SCN of the datafile and redo the file.

  Please let me know how the new controlfiles' SNA is synchronized with the data file and redofile and wea are able to open the database without resetlogs clause.

  Oracle: 11.2.0.4

  OS: Linux

  If your cold backup also includes online redo logs, a RESETLOGS is not necessary.

  The controlfile is created if it does not have a SNA, it reads the data file headers the YVERT database. For a cold backup, all the headers of data file are consistent.  (This is also the reason why a RECOVERY is not required).

• A question about the cold backup

  Hello
  
  I have a question about cold backup. We have a sun server which will be completely rebuilt because of a few hardware problems. This is dev. DB and noarchivelog mode. I have the cold backup of databases. (all control files, data files and I also copied redo log files)
  but the restore operation said that, for the restoration of the database that only the control and data files must be restored and redo log files should not be restored. My question is: in this case how oracle will find redo log files online? because the server is rebuilt, in redologs online directory, there will be no files, so it works?
  I mean I should give the recovery of database until cancel but oracle will create the new files logs by himself again?
  
  Thank you
  Cedric

  oradba wrote:
  You must restore 'false', after "restore the database until Cancel" question "alter database open resetlogs. This will create a new set of onlinelogs.

  Werner

  Why do a "recovery" at all? In the case of the OPs, it indicates that there is a cold backup, including the redologs. Why not just "restore" all files to their original location on the rebuilt server and start the database?

• Need for clarification for cold backup and restore

  Hi all...
  
  I have a lot of confusion about the cold backup and restore section.
  
  Already I posted a scanario this topic and I would like to know a few points of clarity to understand.
  
  
  1. I had cold backup two days before
  2. I create an object * (EMP) * and inserting some records can deliver log switch continiously.
  3. manually I deleted all the physical files (data files, files of control, files, papers, redolog files)
  4. then I published STARTING FORCE MOUNT;
  5. in this case, I get error identification control file.
  6. cold two days before all of the restored files backup
  6 then I run database recovery using backup controlfile until cancel;
  7. I'm issuing select * from emp; I get error

  select * from EMP
  * ERROR at line 1:
  ORA-00942: table or view does not exist

  my QUESTION IS
  
  After that cold backup is complete, I created the table emp...
  during the restoration of old back "there is no emp table"
  
  * - Then I can retrieve table emp? -If Yes, please explain about this... *.
  
  
  Note: REF - LINK https://forums.oracle.com/forums/message.jspa?messageID=11056341#11056341
  
  -Link above says what I did? In this thread, I ask you to concept and logic...
  
  Please, consider NOT like ' * DOUBLE. "

  Not sure why you're confusing this issue? In your other thread, you applied a backup who had two days and there is no evidence that you apply to this log file to archive that had the table create in it. So if you have not restored this log file to archive who had your create table command, it will not be recovered. The most important for you to understand, it's that you have to have the newspaper the point for which you want to retrieve other archiving your recovery will not be able to move forward.

• Should we backup Archivelogs special cold backups?

  B version: 11.2
  Version of the operating system: Solaris 5.10
  
  Here's the script that we use for ad-hoc cold backups. Is it necessary to take the backup of the archivelogs when we do the backup to cold?
  Size of the backup archivelog room is sometimes greater than the backup piece containing the full backup of the comic itself! Then lost too much disk space.
  
  The script that we use

  run
  {
  allocate channel t1 type disk;
  sql 'alter system archive log current';
  shutdown immediate;
  startup mount;
  backup  full database format='/mypath/ORCL_full_%U_%T.bkp' tag='ORCL_full';
  backup archivelog all tag='arch_bkp' format='/mypath/ORCL_BKP/arch_%U_%T.bkp' delete input;
  release channel t1;
  }

  Hello;

  A cold backup is a consistent state. If you do not have to save them. No new archived logs generated during the backup or if you're still OK.

  For other types of RMAN backup, you STILL want it. This ensures that backups of data taken when the command file is recoverable in a consistent state.

• Pre-upgrade cold backup

  DB version: 10.2.0.5
  Version of the operating system: Solaris
  
  We will upgrade of databases about 50 10.2.0.5 to 11.2.0.1
  
  Pre-staged at cold backup of the DBs 10.2.0.5 level, should use us regular cp command, OR should use us RMAN to take the backup to cold? What would you do?

  Hello

  We will upgrade of databases about 50 10.2.0.5 to 11.2.0.1

  Why not 11.2.0.2. The 11.2.0.2 version is more stable and much less bugs.

  Pre-staged at cold backup of the DBs 10.2.0.5 level, should use us regular cp command, OR should use us RMAN to take the backup to cold? What would you do?

  I do not recommend using cp because you cannot verify the integrity of the database and backup. RMAN is infinitely more advanced and have more resources than cp command.

  So I recommend...

  (1) conduct Validade database before backup. To check the integrity of the database
  (2) backup using RMAN 10.2.
  (3) update Perfom 11.2
  (4) to validate the database
  (5) backup database using RMAN 11.2 Perfom.

  We can ask why run the validation database... I recently upgraded from version 10.2.0.5 for 11.2.0.2 23 databases and some databases have been corrupted logical blocks after the upgrade.
  Just do the job safely and make sure that everything is ok

• Measures for cold backup...

  Hello
  
  I am new to DBA, I take a cold backup, some can help me what are all the steps (orders) that I must follow to complete the successful backup of cold.
  
  Thanks in advance

  Hey Rafi,

  I have a question...

  I'm on SPARC UNIX machine and oracle 11.1.0.7
  I did a similar thing for my machine...

  I copied all the files: data files, log files and control to another point of editing files.
  say/u_old / / u_new /.

  Now I restarted the database... Although there is no activity happening in the database, alert always new files are generated.

  Now my goal is to go all out/u_old / / u_new /. In other words, the database should now work from this point of mounting instead of this one.

  What are the steps that I use?

  They would include the steps of cloning the database:

  1 stop immediately;
  2. modify the pfile to the location of the control file, modify the control file to put the new information for the database.
  3. bootable media;
  4. Alter database rename all data files.
  5. starting

  Basically, all of these steps:

  It would be the only process?

• cold backup can use archivelog to recover the database to the point of failure?

  Hello
  
  I have little doubts. In any DB saying we have following conditions:
  
  (1) DB is running in ARCHIVELOG mode.
  (2) cold backup is performed every Sunday.
  (3) no backups hot or the RMAN backup is taken.
  
  so if any failure occurs during the week say Friday. can recover us our database to the point of failure with cold backup? If yes then pls specify the steps how to do it.
  
  Archiving log could apply on cold backup?
  
  
  Thank you
  Shailesh

  Yes. Just make sure that you use "with the HELP of BACKUP CONTROLFILE' so that Oracle ignores the sequence numbers and the SNA in the controlfile and guard"rolling-forward"until the last archivelog that provide you.
  If you have not lost all over again the logs files and want a complete recovery, you must provide log redo file names "as if they have been archived" after applying the last archivelog. This way, you will be able to achieve a complete recovery.
  Of course, you will need to OPEN RESETLOGS.
