• What do I need to use the database shall begin backup mode to perform the backup?

  Hi all

  I have a primary database to 10g (10.2.0.4) with intelligence on a solaris platform. I need to create a different primary eve for the same database.

  I stopped the recovery based on standby and began copy (copy of the os) the existing files pending at the 2nd backup server. But I didn't keep the (mounted) existing standby database into begin backup mode. Is this right?

  Thank you

• What happens when the database in backup Mode?

  Hello
  
  What happens when we kept the database in backup mode, by using the command "Alter database Begin Backup" means;
  
  
  Thank you...

  OK, now my query is whether Oracle freeze the data file header and information is stored in the log file of restoration by progression. So if my backup job continues for 30 min and at the same time someone did some update of database, then how these updates to the information written back to the data file after "Alter Database End Backup'.»

  Oracle only blocks data file headers, no body. Modified blocks will be stored in data files (at control points) even in backup mode.
  If checkpoint has not arrived yet after this update and validation, and DB has decreased, then when it will start it will redo-log automated recovery.

• Update and select ask when tablespace in backup mode

  Hello
  
  I have a question related to the DML statement when the tablespace is in backup mode. Suppose that when putting the tablespace in begin backup mode and then during user times run an update on this tablespace statement and validation of the transaction and any other user run the select query on the same data and image that will appear and where to display the data will be taken.
  
  steps to follow:
  
  alter tablespace users begin backup;
  
  Update emp set sal = 4000 where empno = 101;
  commit;
  Select * from emp where empno = 101;
  
  Now what result will appear and where data will get.
  
  Thank you

  Hello

  alter tablespace users begin backup;
  
  update emp set sal=4000 where empno=101;
  commit;
  select * from emp where empno=101;
  

  As far as I KNOW, the database could function normally and you will not find the difference from the point of view of the transactions. If you check process and the Oracle architecture, bit blurry will be established towards the top and vectors to additional would be saved upward in the newspapers online redo - due to which size of redo would be higher than in normal operations. Second, you must be concerned about the backup - which may not be compatible. In order to better opt for RMAN instead of the user managed backups.

• database in backup mode

  Hi guys,.
  
  If I put my database in backup mode and perform the backup (hotbackup / online) of the database.
  
  When I need to do the restore, can I archive logs at all? (not necessary to recover to point in time) Can I restore data files and do an alter database open resetlogs?
  
  The database will be inconsistent and cannot start without applying archive logs at all? as the data is not stopping when you perform the backup.
  
  Thank you

  You have to do it all again (i.e. the ArchiveLogs):
  FROM: The time where the ALTER DATABASE BEGIN BACKUP (or the first ALTER TABLESPACE BEGIN BACKUP)
  To: The first ArchiveLog after BACKUP END EDIT (or the last BACKUP END of ALTER TABLESPACE)
  Therefore, you should always make ALTER SYSTEM ARCHIVE LOG CURRENT at the end of the backup mode and capture this archivelog in your backup.

  The database will be inconsistent (and DOES not) until and unless you apply the redo (archived).

• RMAN and Begin backup mode

  Hi guys I have a couple of questiopns...
  
  I want to know if data is written to the DBWR data files when the data file is starting in backup mode.
  
  What is the difference in the creation of archive log during normal operation of a database and a database for the RMAN backup operating?

  user13087302 wrote:

  Normally, Oracle should write that change in redolog files. But if the tablespace is in backup mode, then entire block will be set redolog as soon as this change is 1 took place on this block after activating the backup mode. Therefore, we log redo generation face massive if the tablespace in backup mode. So, logically you should be able to recover to the last CNS you have in hands.

  What do you mean by the last SNA. Does the SNA before putting the tablespace in backup mode? Does present data in other files will be also lost, even if they are written in the data files...

  PLS, look at:

• Software in trial after restoring backup mode

  A few weeks ago I had to restore my Mac from a backup.  Since then, Adobe CS 6 is running in trial mode.  The problem is, I don't have the registration information.  My company what guy initially installed the software no longer works for the company and is not left behind any purchase information or installation discs etc..  Is it possible to get out of without test mode?  Perhaps with the serial number of the computer?  Thanks for any help.

  You must purchase the serial number of the software.  You will probably need to work with whoever the new computer is to get this resolved. It seems that the company has the software, then it will be for them to solve this problem if so.

• "Is it possible to oracle 11g DB without journal Archive OEL 5 of the backup mode.

  Hai everybody,
  
  I am new to oracle, I want to take the online backup without log mode Archive is possible? due to the database to archive performance is little low, that if our database is in no fashion show archive log cannot be greater? Oracle 11g provides another way to perform a backup online without log mode archive?

  At the time of database archiving is it take system resources?
  you mean if db is in archive mode the db works the same like noarchive mode

  How long you have used to get the answer here?

  worth it?

• ALTER TABLESPACE BEGIN BACKUP MODE

  Hi all
  When we issue alter tablespace begin backup command then freezes the data file headers and all modified blocks will be written to streams and when we issue end backup command then the database will write the blocks changed to data files by accessing files redo.
  my doubt is suppose archiver process archive redo files and all redo files are overwritten. now how the database will write the changed blocks to restore and database dealing with this task.
  
  TIA

  "Hot backup" is obsolete with 10g or more recent technology as Rman covers this much better.
  Please switch to RMAN at your early convenience.

  Also, as the database must be in archivelog backup online, it is not a problem, that the online redo log files are overwritten, like recovery will use two online redolog files and archived.
  Your question doesn't make sense to me.
  Redo are written in files LGWR, ARCH Archive files. Changes are written to the database by DBWR. All who are independent processes, and the changes are written to redo front to be written to the database.

  To work around "printing in rescue mode" ensure that all cartridges are installed and no are exhausted.

• archivelog mode and hot backup

  Hello
  in g R2
  This is the hot backup:

  online backup
  
  A backup of one or more datafiles taken while a database is open and the datafiles are online. 
  When you make a user-managed backup while the database is open, you must put the 
  tablespaces in backup mode by issuing an ALTER TABLESPACE BEGIN BACKUP command. 
  (You can also use ALTER DATABASE BEGIN BACKUP to put all tablespaces in your database into backup mode in one step.)

  would we in log mode archive to do an online backup?
  
  Thank you.
