  As to this subject? You calculate the RCS based on any time you want. If you change the time, you must be unambiguous. See http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:3297071155886

  You can use scn_to_timestamp and it is converse to switch back, at least the previous 5 days (in current versions). Granularity of SNA varies according to the version of 5 minutes and 3 seconds.

• Hot backup maintained by users script? 11g (Unix) good measures?

  I'm looking for a script to hot backup maintained by users for GR 11, 2 under Unix. My client does not want to use RMAN.
  
  I think that the main steps are:
  
  -alter system switch logfile
  -change the system log archive current
  -alter database begin backup
  -alter database backup controlfile (and also the backup on the track)
  -copy the data files, archives, remake, controlfiles to another location
  -take the database out of hotbackup mode
  -J' have also capture spfile and other config files
  
  Recovery is just restore to the original location, at STARTUP and backup of the end.
  
  Basically, there may be cases where we have archives that have been made after the hotbackup we want to apply. In this case, it is RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL in order to apply the archives.
  
  His right?

  After you take the database out of Hot Backup, you must switch logfile (preferably several times) and backup generated archivelogs.
  You can back up archivelogs while the database is in backup mode but you must also back up the first archivelog (s) after the backup of the end.

• More redo generation during hot backup

  Hi all
  I want to know more over the generation of redo during hot backup.
  I know that in this case the data file headers are frozen. But I want to know how the whole thing goes. All did this experiment practically?
  Did any problems of performance because of this?
  
  
  
  Thank you
  Rafi.

  Hmm well, it basically means like this, assuming you have a block filled with 1s like that,

  ----
  1
  ----
  1
  ----
  1
  ----
  

  And this is the copy of the block that was sent to the backup by you and was taken over by the command cp o/s. While the cp command will make a backup of the block as it can be read much more small piece that, suppose that he would start with the 1st part of the block and starts copying to the o/s somewhere. At the same time feel, DBWR peaks upwards again and written on block 2, like that.

  ----
  1
  ----
  2
  ----
  1
  ----
  

  It can from the flie is always online and is available to be used by the database. Now, you have a problem. The image you sent for backup isn't th that is here now. Next time what cp command would return, he would find 2 instead of one in the 2nd part of blok and copy it since it is a mute command when comes to oracle. So now that you have in what you wanted in the backup and the backup are not the same images. You have a cracked now block which is of no use for the recovery. To this end, in the case of the hot backup, the first image of the block time is copied and is maintained. This saves us from the State to have 2 there. We have all the 1s who sent us. Now, if in the case, dbwr also changes the block, the original help oracle reover the block properly.

• Oracle hot backup confusion

  Hello world
  This is a confusion on hot-backup Oracle.
  
  Suppose I have 3 online Redo Logs and I put a tablespace in backup Mode.
  So, whatever changes are made, Oracle will begin to generate redo for the entire block to avoid the fractured blocks.
  
  My Question is if, while doing this all my online Redo Logs files/members of Wat is full how do then Oracle manage to move forward and continue to save Transactions/changes to a Certain block in the Tablespace.
  
  
  1 > oracle runs a recovery from the archived Redo Logs once the Tablespace out of backup Mode.

  Thank you and best regards,

  I'm even not sure what #2 means! Anways.

  Suppose I have 3 online Redo Logs and I put a tablespace in backup Mode.

  No matter how many redo log groups you have and as I know it has no relationship to a tablespace in backup mode either.

  So, whatever changes are made, Oracle will begin to generate redo for the entire block to avoid the fractured blocks.

  Partially correct! The entire block is copied only for the first time . For subsequent changes, only agents of change go in the stamp newspaper, and from there, the redo log files. This is exactly what happens to a tablespace is not not in backup mode.

  My Question is if, while doing this all my online Redo Logs files/members of Wat is full how do then Oracle manage to move forward and continue to save Transactions/changes to a Certain block in the Tablespace.

  Does that mean exactly? If you complete the redo logs, switch journal will follow making the LGWR move from the current group of redo log to another, triggering the control point, which would make the DBWR write buffers in the data file. I don't know what is confusing?

  Edit: I apologize, I read this point a little too fast! If all the log files will be filled, database could be suspended. There will be transactions more because there is no place to write their vectors of change anywhere. Sorry, I realized in the first time you were talking about switching to the standard newspaper.

  1 > oracle runs a recovery of archived newspapers again once the data file is underwritten in backup Mode.

  What recovery? Before files go in the backup, there is a 'global' checkpoint which is executed for them, pushing them all buffers in the cache for them and then once the point control freezed for them, still let all read/write operations. Once they come on the backup mode, when the next time a checkpoint is made, then their number is synchronized with the rest of the database. Where the recovery comes into the picture here?

  2 > or y at - it a fitness State/Re-sizing of the redo log file online space between other Segments.

  As I said before, I didn't at all mean that point yet?

  Yes.

  I would like to point out something that you may not realize: Windows 8
  has two interfaces; the modern/Metro Interface (which may be all the)
  you have looked at) and the traditional desktop Interface. You can use
  one or both. This traditional desktop Interface is almost
  identical to the interface of Windows 7. the biggest difference is that
  There is no Orb start clicking to bring up the start menu.
  But note that you can get the ORB start by using one of the many
  third-party programs, are free or very cheap (the classic interface
  http://classicshell.sourceforge.NET/ and debut8 to
  http://www.stardock.com/products/start8/; my personal preference is
  Debut8, but they are both very good).  And goes from an interface to
  the other is very easy; There are several ways, but simply by pressing
  the Windows key is perhaps the easiest.
  I use Windows 8, almost exclusively with traditional workstations
  the interface and with 8 Start installed. If you were to look at and use
  my computer, you would have a hard time realizing that it is not
  Windows 7.

• Hot backup question

  Our DBA functions are currently outsourced, and I'm just curious about something.
  
  We asked them to copy a schema from our database of Production (during the day) to its equivalents in the acceptance and Test environments. We found a problem in that the maximum value of a primary key on a table was 100121, and the sequence used to generate the value of the primary key is only 100081.
  
  Is a risk to a backup in hot and any annex a backup must be taken after hours? Or maybe did something wrong?
  
  
  Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

  If the request was to copy only a single schema, then it is unlikely that a "hot" backup would have been used. Most likely exp/imp or expdp/impdp would have been used to export the Production schema and import it into the other two databases.

  The sequences are always 'a problem' when export - import is used when the database is active. Export of the sequence and the export of the table (or tables) using the sequence are not at the same time / SNA so that the values can differ as they have updated in the source database.
  The plan is to restore order in the target database by manually incrementing until it reaches the desired target (100122).

• Using more of a VMWare backup recovery

  Hi all

  I'm sitting here und think next idea:

  We have 10 servers that must be saved. We use a VDR (VM Backup Recovery) for this. Thus, sometimes the catalog crashes and it takes neerly a day to fix it. While this time I can´t of backup or restore anything.

  These backups are on the same SAN as my ESX machines. So I have the big problem, if everything crashes (raid or more than 1 HDD) I have no chance to recover anything.

  Yes, I know that this is not 100% optimal. either way... we have no money to buy a second SAN!

  the idea was to develop an other VDR and connect it to a Terastation. Speed is absolutely secondary. This VDR would save computers same like the first VDR. (not at the same time, for example SQL Server is saved on VDR1 on VDR2 and 06:00 on 09:00)

  The biggest would be:

  -If VDR 1 catalog crashes, VDR2 works and I can fix the VDR1 without missing the backups or recoveryoptions

  -If my STI SAN crashing, I can use my Terastation to fix everything (the speed is secondary)

  What do you think of this idea?

  Good bye

  Andy

  You can define 2 different backup locations in a single device. So you can save on Monday for the first location and Tuesday for the second and so on. When an integrity check runs more than 24 hours, you have the second location-data store to restore on the same device operations. If you have enough backup-time, you can also save each VM twice in one day in two places at different times. In the event of a disaster you will be lucky and maybe lose only a location of data store and have all your backups without waitiing for the completion of the audit of integrity or something as a recataloguer. Up to now this works very well in my environment with 5 appliances and 180 VM. I use no more than 30 virtual machines for a single device, because integrity, check runs throughout.

• Where is the official Oracle documentation that describes the hot backup?

  I used the cruelly utility failure to search for Metalink and Google, but the closest thing, I found is a description on "ask Tom".
  
  I'm looking for official Oracle documentation that describes what is happening internally during a hot backup. There are many websites and blogs out there that describe, but I'm looking for a description of Oracle themselves. The only things I found in the Oracle documentation until now is to know how to start and stop the hot backup, but not what is happening internally. GR 11, 2 preference if it made a difference.
  
  Thanks in advance.

  Hello;

  Its probably gone RMAN covers this.

  The closest would be:

  Backup and recovery reference 11g Release 2 (11.2) E10643-06

  Or

  Backup and recovery User Guide 11 g Release 2 (11.2) E10642-05

  See Chapter 8 - Concepts of backup RMAN - online backups and backup Mode

• UNDOTABLESPACE and TABLESPACE TEMP in cold or hot backup database

  Hello
  
  I have a BACKUP, including logs generated after the backup archive. What is the use of the UNDOTABLESPACE and TABLESPACE TEMP datafile data file backup? When it is used?
  
  
  Kind regards
  
  007

  >
  I have the archives which have all entries are committed in it. Undoinformation is necessary for the restoration and recovery of the database? Can u explain more clearly?
  >

  The archives are as congested entries of redo logs. And the redo logs contain all changes to the database. Information cancellation will be there in the segments of cancellation that there can be some uncommitted transactions active in the segments of cancellation. Cancellation information is necessary to put the database in a consistent state. It is one of very important storage similar to the control file and system tablespace to bring a database

  Edited: Imagine a scenario. You make a backup hot at 07:00. And there are a lot of transactions happening before and during hot backup. For ex, I run a massive update to a table. This will cause the recovery to write logs of recovery that will be eventually written to logs archived. Now, you finish the backup mode. But I have not validated or cancelled my transaction. Say to the reasoning, I roll back the transaction.

  Now, you restore the backup. Do you think that my transaction will be in inconsistent state? Redo logs and archiveed newspapers had my transaction changes/redo entries. If you are not using undo in recovery segments, what will happen to my operation that I rolled back? Without cancel, half of my transaction (even if they were not truly committed) will be sitting in the database. This is where undo tablespace helps us in rolling back the transaction during your recovery. Remember, the cancellation information "peuvent" not all in recovery if you do not a complete database recovery. But Oracle should know that. If you need to undo tablespace in your backup set.

  I hope it's clear now
