• The database Point-in-time recovery

  Hi, experts.
  I have an interesting question. For example, I have consistent backup, backup and archivelog next cintrolfile. I want to recover the database to a point in time or SCN in the middle of this newspaper. How to check, before you begin the recovery, that this point in time, or SNA will be compatible? How to find coherent whole SNA or SNA that will I can recover the database for?

  How to find coherent whole SNA or SNA that will I can recover the database for?

  Not sure if we give the same meaning to "compatible", but all the SNA are "compatible": see this AskTom thread, where you can read

  the system change number (SCN) is the clock of Oracle - whenever we are committed, the clock
  increments. The RCS has just marks a coherent point in time in the database.

• Point in time recovery scenario.

  Hi all

  I worked on the time of recovery as point below and restored successfully as below,

  First, I checked the data,

  SQL > SELECT * FROM test2;

  NAME

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

  Haja

  Knani

  Pradeep

  Barry

  SQL > SELECT * FROM test3.

  ADDRESS

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

  MIT Inoftech, Chennai

  SQL > select to_char (sysdate, "mm/dd/yy hh24:mi:ss'") twice;

  The clock DB

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

  25/03/15 12:35:34 - based on this basis of time I restore and recovery, my question is also in service at that date and time only.

  SQL > UPDATE test2 SET name = 'Raja' WHERE name = 'Haja;

  1 line update.

  SQL > SELECT * FROM test2;

  NAME

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

  Raja (previously this line contains the values as Haja.)

  Knani

  Pradeep

  Barry

  SQL > SELECT * FROM test3.

  ADDRESS

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

  MIT Inoftech, Chennai

  SQL > DROP TABLE test3.

  Deleted table.

  SQL > SELECT * FROM test3.

  SELECT * FROM test3

  *

  ERROR on line 1:

  ORA-00942: table or view does not exist

  then I got db in editing step then did restore and recover successfully.

  RMAN > RUN {

  UNTIL ' TO_DATE (20 MAY 14 12:35:34 ',).

  "MM/DD/YY HH24:MI:SS") ';

  RESTORE THE DATABASE;

  RECOVER THE DATABASE;

  }

  I will come to my question, before I took the date and time of double as below,

  Scenario-1
  

  SQL > select to_char (sysdate, "mm/dd/yy hh24:mi:ss'") twice;

  The clock DB

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

  25/03/15 12:35:34,

  If I use above the date and time can restore and recover the works.

  Scenario - 2

  I did all dml and ddl change as I mentioned above but did not date and hour only instead manually I change date and time as below,

  25/03/15 12:55:34 (I tried this after 20 minutes and time mentioned is given by myself, did not double)

  "but my restoration and recovery completed successfully, but dropped table is 3 not restored and update the data in row as"Raja"want it as ' Haja" than the way it has been done before update, but has not changed.

  What is the problem here, why my restoration not complete successfully using manually mentioned date and time when it is successfully done using double query time-out.

  
  

  Suppose that I forgot to take it twice then Am I can't restore and recovery?

  Is there any solution or own way is here to fulfill my need. then, kindly share with me.

  
  

  How can I optimize point in time when I don't have second time zone. Suppose I need to take backup in before 5 days and at any time (for example)

  Hello

  I will explain clearly, sorry for the inconvenience,

  I hope that got 1 scenario do you understand,

  In scenario - 2 there is not more complexity, just that I had restore and recover successfully when I gave ALL to the base double taken as 25/03/15 12:35:34 in scenario 1, but in the scenario-2 I tried to restore and recover with the VALUE UNTIL here I gave the date and time as 25/03/15 12:55:34 by manually by myself not selected double date and time by this time restore and recover over expected but table and lines are not restored and corrected.

  Anyway thank you for your Information, I will loot in a SET command up to for more information.

  It is real simple, and after selecting sysdate double at some point has nothing to do with it.  The time of SET up is powered continuously "manually". He does not know or care that you provide once you have determined by selecting sysdate in double to an earlier point in time.

  You did your test update (change "haja' to 'raja' some time between 12:35:34-12:55:34.

  In scenario1, you did a TIME FIXED up an hour before your update.  Were recovered at that time and your data recovery operation as it was before the update... as it was at 12:35:34.

  In scenario 2, you did a TIME FIXED up to one hour AFTER your update. Thus, the recovery operation recovered all activities at 12:55:34.  It was AFTER your update, so when the recovery is complete, you have had your data as it was at 12:55:34.

  To recover to a point in time spent you have to RESTORE the database from a backup that is older than the recovery point at the time.

  Unless you have set a Restore Point of Flashback earlier and newspapers flashback and archivelogs.

• Point in time recovery because of the lost archives

  Hello!
  
  My question is when you lost a few archives so now you need to perform point in time for recovery.
  Let say you had 8 archives and 5th archive is lost so now, you can only recover up to 4th arhive. Rest of the archives after 5th are lost they may not be applicable.
  
  I want to ask is possible that we could apply the archives after the lost archives. ?
  
  concerning
  Usman...

  No....

  Why we can't apply because the lost archives will be a series of SNA that are required and transactions in archives according to the lost archives may depend on transactions in the lost archives.

  The integrity of the data cannot be maintained if this is permitted.

• Where can I get a copy of the backup and for windows xp hp Recovery Manager

  Compaq Presario SR2010NX

  Windows XP

  I had to reinstall Windows on another drive of Windows for the C: drive so that I can make a recovery of the D: partition. However, now I have more have "HP Backup and Recovery Manager" to run Windows and cannot make a recovery with F10 at startup.

  What I need to solve the problem in my view is another copy of the "HP Backup and Recover Manager". Where can I download this from where to buy it? I found a copy for Windows 7 and copies for laptops, but nothing that I need. Any help is greatly appreciated.

  Hello:

  As you discovered, is not available for download or purchase, etc.

  Why you can get it online for laptops, for hints. I looked too.

  I guess you have tried one of the downloads for laptop to XP, and it did not work?

  I know I should.

  The only way, in my view, that it is possible for you to get the program, is to buy a set of recovery discs and use them to reinstall XP. They should reinstall XP and all programs from your PC and recreate your recovery partition.

  You can see if HP has them by reading the info on the link below (I doubt they make, but you may as well ask).

  If HP does not, you can still get this provider on the link below.

• RMAN incarnation - Point-in-time recovery

  Hello
  
  I have my running RMAN backup.
  
  My database is running in Archivelog mode, I open the database with resetlogs option. All of a sudden my entire database got currupted.
  
  Now, I have previous RMAN (incarnation backp) + current archivelogs generated from this morning.
  
  I'm sure that the embodied backup RMAN can be restored. Here, how to apply the archivelogs generated after setting open resetlogs option. Is there data loss? How to handle this scenario?
  
  Thank you
  KSG

  Could you please explain with an illustration on the same?

  Just restore and recover the database. From your first post, I understand that you have lost any data base due to you must restore controlfile first (also if you lost spfile restore everything first) as

  export ORACLE_SID=
  rman target /
  startup nomount;
  restore spfile from 'autobackuplocation_or_fullbackuplocation';
  startup force nomount;
  restore controlfile 'autobackuplocation_or_fullbackuplocation';
  alter database mount;
  catalog start with 'full_backup_location';
  catalog start with 'archivelog_location';
  restore database;
  recover database;
  alter database open resetlogs;
  

  No no that if you do not have autobackup controlfile then restore controlfile from other backupsets (who understand the system tablespace).

• Several Flashback Database to the time prerequisites

  Current time: 17/12/2013-13:22

  Created restore point guaranteed: 10:53 09/12/2013.

  More old Flashback Time: 10:34 09/12/2013

  
  

  A Flashback Database timestamp 17/12/2013-06:30 was carried out at the 12:00 17/12/2013. (Done Resetlogs).  It's my understanding that a new incarnation is created when I resetlogs.  Guaranteed restore point was created under the old incarnation, but it seems to keep the archivelogs recovery guaranteed, even if the database has been Databased Flashback.

  Is it possible database flashback by timestamp 10:34 09/12/2013 (oldest flashback time) even if we have already done a recovery (flashback by timestamp database) at 17/12/2013 06:30?  I am concerned about corruption.

  Thanks in advance.

• Point of time of recovery to a different database

  Hi all
  
  Does anyone know if it is possible to recover a table to a separate database? For example, if I have backups from last year and you want to compare the emp table of June 2009 with the emp table now? I don't want to mess with my production database, so I would like to restore the data to a test server and make a point in time recovery on a datasbase test.
  
  Thanks in advance

  If you have 10 g +, you can use FLASHBACK DROP.

  Otherwise, you can consider restoring full RMAN backup Table.

• Backup point-in-time with backup to network share files

  Hi all

  Oracle Database 11 g Release 11.2.0.3.0 - Production - on Windows 2008R2 64 bit

  I'm still getting hot RMAN backup and that you have configured our backup as follows:

  -Nightly rman backup to local drive (ORAFRA) hot and then copy the entire ORAFRA folder on a network share (which will be on the Strip).

  It adheres to RPO my company (recovery point objective) of 24 hours, because if my real server goes down I can restore in the previous 24 hours.

  HOWEVER, my question is more to be able to make the point-in-time recovery using disaster file sharing network. I guess I can make the point in time at any time prior to my backup complete (using SNA #)... but if I wanted to be able to do point-in-time recovery AFTER my full backup, how would that be possible?

  Example - full backup at 19:00 every night. The incident occurring at 23:00. words I can only return to 19:00 or before. How can I configure I can restore, say at 22:00, using network backup files?

  Thanks in advance!

  Yes.  You must use the syntax for using backup controlfile recovery and do a resetlogs.

  With rman, you might be able to avoid the resetlogs, depending on whether the point-in-time is your real goal (which could be the situation you've lost again them online - or maybe not so rman the controlfile and newspapers archived periodically).

  You might investigate databases in waiting, many places decides that they are worth the cost compared to the possible losses.  And even if you do not, the concepts of recovery help to understand these things.

  You can also consider, the purpose of backup is resumed and rman is to manage the recovery.  It is really important to understand the concepts, to the point you can do it in your sleep (literally nearby, here), but it is also important to understand the tools.

• Backup and restore database, tablespace

  My oracle's 10g.
  I'm new to rman utility. When I tested the backup of database and a tablespace before making certain changes made to the data (e.g. Add folders to other tables or change or delete some records) and did surgery recovery and the restoration of the database and a tablespace after these changes. But I found that these changes have remained there.
  
  My directions of test:
  SQL > shutdown immediate;
  SQL > bootable media.
  RMAN > backup database;
  RMAN > backup all archivelog entry delete;
  SQL > alter database open;
  SQL > alter tablespace ABC offline immediate.
  RMAN > backup tablespace ABC include current controlfile;
  SQL > alter tablespace ABC Online.
  = SOME CHANGES TO THE DATABASE BY INSERTING/UPDATING / DELETING =.
  SQL > shutdown immediate;
  SQL > bootable media.
  RMAN > restore database;
  RMAN > restore database;
  SQL > alter database open;
  SQL > alter tablespace ABC offline immediate.
  RMAN > restore tablespace ABC;
  RMAN > recover tablespace ABC;
  SQL > alter tablespace ABC Online.
  = CHANGES OF DATA SHOULD BE LOST. BUT NOW THAT ILS IS REST. WHY? ====
  
  Also, what is the difference between the database backup/restore/recovery and backup/restore/recovery tablespace? Or when is the time to use them?
  
  More practical is if I made a backup of database, at 10.00 and 3 backups tablespace ABC at 10:00 12:00, 14:00.
  Today at 20:00, I have 2 tasks:
  1. restore tablespace ABC 12:00 the status and create a new tablespace DEF, which is the same in ABC 14:00;
  2 put all the data of the ABC from 10:00 tablespace to another oracle newly installed in a newly installed machine.
  
  Can someone tell me how I can finish these tasks? Thank you very much!

  Hello

  Sorry for not being clear enough.

  This means that I can only recover data to the tablespace recovery state?

  Restore/recovery tablespace controls may lead to a full recovery.

  but I want only to restore a space at the beginning everything while keeping others more recent. What do you suggest me?

  If you want to make a point in time recovery for a subset of tablespaces, you must run a TSPITR.
  To do this, follow the link in my previous post.

  What you said really works. These changes losts. But I encounter another problem when retried the delivery and received a msg "RMAN-20207: until THE MOMENT or.
  RECOVERY WINDOW is before the RESETLOGS time' to the command "restore." What should I do now?

  By the , you have created a new incarnation of the database.
  If you want to restore to a point in time of the resetlogs before you change the incarnation (check first with: INCARNATION of the rman LIST).
  To restore an incarnation previous use:
  < reset="" database="" to="" incarnation...;="">

• Backup and restore of the different States of a database

  Hello
  
  In a development and test system, we want to save and restore the different States of the entire database.
  
  This means, we start with a full (TAG 1) backup of the database.
  On a day team has done in the database, after that we take a full backup (TAG 2).
  The next day, do us a restoration of the TAG 1 and the B team some works, after that, we take a full backup (tag 3).
  Then, we want to continue: restore from TAG 2, TAG 4 backup, restore TAG 3,...
  
  I tried follwing RMAN procedures:
  
  Backup (backup consistent cold)
  RMAN nocatalog target.
  
  SHUTDOWN IMMEDIATE;
  FORCE START S/N;
  SHUTDOWN IMMEDIATE;
  BOOTABLE MEDIA;
  backup as BACKUPSET COMPRESS database ' TEST1' tag include current controlfile;
  ALTER database open;
  
  
  Restore (database in time recovery DBPITR point)
  # get RCS with tag backup rman list «...» »
  # add - one for the RCS, use it in the script for NNNN
  
  RMAN nocatalog target.
  stop immediately;
  bootable media;
  restore the database to the SNA NNNN;
  recover the database unitl Yvert NNNN;
  ALTER database open resetlogs;
  
  Problem is: when we try to go back to an older version, we get a
  RMAN-20208: until this CHANGE THAT either before RESETLOGS change
  
  No idea how to switch between the different States of the database?

  I think you are looking for incarnations. (I know you said 11g, the doc here is 10 g, I love the research/layout better than the 11g docs).
