RMAN restore until THE SNA in DATA GUARD environment

• A few questions about the design of Data Guard

  Hi, I have a few basic questions around design Data Guard

  Q1. Looking at the instructions of Oracle for the creation of a logical standby, he recommends first creating a physical standby and then convert waiting logic. However, I thought that a logical standby might have a totally different physical structure of the primary. How can this be the case if a logical standby first starts his life pending physical (where the structure must be the same)?

  Q2. It is a normal practice to back up your database before as well - if yes why?

  Q3. Can RMAN back up a database of the day before while he is in the State mounted (rather than opening it)?

  Q4. What is the point of cascade redo apply rather than just get the primary ship to each standby?

  I guess you could try to reduce the latency of node to node if some the day before were quite remote from the primary

  Q5. Is it possible to convert a physical logical Standby?

  Q6. What number best of Standby, you can have - Oracle suggests 30 but I thought I remember reading somewhere regarding the 11 GR 2, that this limit has now been increased?

  Thank you

  Jim

  Hello again;

  "begins each logical waiting first her life on hold physical?"

  Its the only way I ever did. I think it is the simple way to do it.  By the presence of a physical standby first you have already confirmed the network and most of the settings for Data Guard so that you can focus on only the logic of the standby database configuration.

  Chapter 3 of this book, it's easy:

• RMAN-20207: until the RECOVERY WINDOW, which was before the RESETLOGS

  Dear friends,
  
  I'm picking up some time and I have used this SQL in my RMAN
  
  reset the database incarnation 1;
  
  run
  {
  until ' to_date (3 Aug 10 17:50 ',' MON-DD-YYYY HH24:MI:SS') ";
  restore the database;
  recover the database;
  }
  
  and I get this error: RMAN-20207: until the RECOVERY WINDOW, which was before the RESETLOGS
  
  I thought changing the incarnation will solve the problem. I have only 2 incarnations, which is used after that the resetlogs which is number 2. So I now use 1 incarnation.
  
  How should I go about this?
  
  Thanks in advance.

  Ok...

  Now, what you have to do: If you want to point at the time of recovery, you must have a valid backup plus archivelogs in order to recover up to the desired time.

  From now on, full backup is available for the time that you asked, however archivelogs not :(

  You must make available, controlfile catalogue and begin to restore, recover up to the hour. Then open with resetlogs option.

• Oracle will consider the creation of a day 2 hands on the documentation for Data Guard?

  Hello

  Oracle will consider the creation of a documentation of son of hands 2 day for Data Guard?

  There is already an OTN 2 day of CARS and performance tuning documentation.

  Thank you

  Updated - she sent the link to this topic for the Product Manager Data Guard.  As a result, Oracle may or may not consider creating 2 days hands on Data Guard documentation, but no doubt they consider at least considering creation day 2 hands on the Data Guard documentation.

• How the PopUp open for every 15 minutes until the user saves data

  Hi all
  
  I'm working on an application where I need to open a popup for every 15 minutes until the user saves data and stop after users register data. I'm not able to get the idea on how it could be done. Please post some views in which it could be done.

• Flashback Database using Data Guard environment

  11.2.0.3/RHEL 5.8
  
  I came across several documents that speak of FLASHBACK DATABASE configuration in dataguard environments. We have several
  Physical DBs sleep (Single Instance & RAC) running in our shop. I would like to know two or three major (common) use of FLASHBACK DATABASE data child care settings.
  
  I understand one of the uses mentioned in the below URL ie. a logical error recovery
  
  http://uhesse.com/2010/08/06/using-flashback-in-a-Data-Guard-environment/
  
  I would like to know what are the other major/common use of Flashback Database River in environment DataGuard

  A few other uses:

  (1) flashback allows you to test your DR. So you can activate your watch. Test the connectivity of network/applications and features on your recovery site and when done return the database to a physical standby. It must however ensure that this is allowed in your environment. In some places, I worked, it would be a big no, no, because they have no needs of data loss. However some companies that will allow as long that the watch is delivered in place for some time.

  (2) in the case that you do a failover for a reason, but what has been the main site would then become available, you can flashback what has been your primary to make the eve rather than re-instatiating the database from scratch.
  For example. You have a power failure on your main site if perform you a failover and your watch becomes the principal. Once it's your main site is back online, you can convert your previous primary in a day before making a full return/restoration (or any method you choose) to recreate your standby again. However you also have the option to use flashback on this database and then convert it to a watch because it would be potentially faster than the re-instantiation of the day before.

  You must choose an SNA:
  -which is higher than any file data YVERT
  -to which you have linked archived red balls
  -who is older than January 1, 2010.

  You can try to view the related archived redo log backups with:

• Restore the size of the log in Data Guard configurations

  DB version: 11.2
  Platform: Solaris 10
  
  We have currently a DB production which is not Dataguard.It has a load of joint working: some processing OLTP and batch.
  Its size of redo log is * 100 * MB.
  
  We will create a database with the requirement very similair but this DB will have primary standby (Data guard) and real time applies.
  
  To adapt to the requirements of dataguard, we should reduce the size of the recovery online newspapers? That is to say. Transport of small pieces of roll forward is better than carrying more. Right?

  Hello;

  If you use "real-time applies" the key is not the size so that the standby Redo Logs.

  In most cases, 100 MB is fine. Newspapers to sleep again must be the same size that it again.

  With 'real time applies' SRL act as a buffer.

  Unless you have a real problem with the size of do it again I would not change it.

  An excellent source of information on this is 'Restore the Services of Transport' in ' Data Guard Concepts and Administration 11 g Release 2 (11.2) "E10700-02".

• RMAN restore in the State of the mount in Oracle 11 g DB

  I have a question which can be very naïve, it is to confirm if the RMAN restore happens in the mount status of data or can it also happen when the DB is in open State?

  Please get back with the answer to my query.

• Cost associated with the implementation of Data Guard

  Hello
  
  What are the implications of cost migration to oracle Standard edition to Enterprise edition (I think data hold is not available with standard edition)?
  I just need a rough estimate to make a presentation. Also is there any additional cost to implement Data Guard? Finally, it is reasonable to assume that the average cost of a server of the p series (4 processors with 16 / 32G of RAM) is around £2000 ($3500).

  Hello;

  I can perform a failover or a failover with Data Guard Broker in about 20 seconds. If I don't use a broker, it takes about 3 minutes.

• 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

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

  3 0 1111 115840 78859075 FAILED

  After that: watching the content of v$ database_block_corruption;

  Show me a lot of lines like this:

  3 4384 1 0 ZERO ALL THE

  3 4334 1 0 ZERO ALL THE

  ...

  33 selected lines.

  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 ;}

• Physical movement of the databases using Data Guard

  Hi all

  We need to move our equipment to a new physical location.

  Our production database (11.2.0.4) is replicated to another computer using dataguard (MaxAvailability mode)

  The plan was to move the machine SRD first Monday, then the database of production during the next weekend.

  Do you have an idea how to do a 'pause' the replication when the move will take place for two servers?

  We do not want to do a failover because the production should not be available over the weekend.

  Thanks in advance,

  Renaud

  Do you have an idea how to do a 'pause' the replication when the move will take place for two servers?

  There is no such method of the break, but you could defer the primary log shipping to wait.

  ALTER system set log_archive_dest_state_2 = reporter; #assuming that log_archive_dest_2 on the primary it again waiting for ships

  But, you must make sure that the archives on the primary are not lost or deleted after reporter such as these are not available on standby.

  Once you 'enable' the destination deferred, Eve should automatically catch up with the primary.

  (2) standby: start [if ADG], otherwise then starting in the State
  (3) primary: DGMGRL > EDIT DATABASE 'Standby_DB_UNIQUE_NAME' PROPERTY SET LogShipping = ON;

  No need to start MRP waiting, because whenever the broker started, MRP will be initiated.
