• 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.

• 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:

• init < SID > .ora during the Data Guard configuration - advice needed

  Hi all
  
  I'm looking to implement data between 2 groups CARS hold. A single cluster will be primary and the other is disaster recovery.
  
  I've already implemented the two 11 g R 2 RAC clusters on RHEL 5 and now need some good docs for Data Guard install tips.
  
  Can someone direct me to the right info step by step for custody of data between clusters RAC - detailed explanations of each of the configuration steps would be helpful too, especially around the file init.ora configuration changes between primary and DR sites
  
  Very appreciated

• Restore the iTunes app data backup and backup to iCloud

  My iPhone 6 has been stolen. I got iCloud backup enabled, and the last backup was 2 days.

  I do a full backup encrypted via iTunes it also sometimes manually, the last time was 1 month ago.

  I bought a 6 new iPhone as a replacement. When I tried to restore from your backup, everything (photos, applications, settings) seems to be restored very well, but most of my applications (not all) were missing from their app data.

  More importantly, Google Authenticator, which had all my keys to two factors and in hindsight, an app that follows the historic activity and has experienced a year of daily data stored on the device value authentication.

  I don't understand why it affected only a few applications, but not all. Most applications requiring a login account is no longer connected, makes me think that their data was not were properly restored either. I found one or two applications that had some settings restored properly, but most of my apps seem to be returned to a State of the new facility.

  I tried to re-do the restoration of iCloud again and got the same results.

  I'll try the iTunes backup restore then, but even if it works I would miss even 1 month of a data value. Is it possible to recover this data? I guess that that's actually in the iCloud backup 2 - old days, but for some reason any, that he is unable to restore.

  Is it possible to combine the full restoration of iTunes and then update with the most recent data backup to iCloud app?

  Update: when I tried to restore the iTunes backup I received this error a few minutes:

  

  Is it because the original phone was an iPhone 6 and the new phone is a 6s? Is it possible to access my backup?

• RMAN restore until THE SNA in DATA GUARD environment

  Hello

  OS = RHL5

  DB = 11.2.0.3 primary and 1 physical database paused.

  I have a huge request changes tomorrow and its possible that I have an obligation to RESTORE the database 5 hours back because the application.

  I think to be adopted following the method of the official documentation of the Oracle (untilClause):

  MOUNT FORCE OF START

  RUN

  {

  UNTIL THE SNA 1418901.  # The necessary number SNA will be used here.

  RESTORE THE DATABASE;

  RECOVER THE DATABASE;

  }

  ALTER DATABASE OPEN RESETLOGS;

  I will of course take Level0 backup tonight and LEVEL1 backup before the start of the work.

  My humble question is that: If this is the good method I adopt? and if so, then what about physical databases eve? Is that something to restore/recovery too? It is not required or waiting for database necessary to create again (which I'm afraid of)?

  Flash back is not enabled.

  Pack of thank you for the suggestion.

  Best regards

  You can enable FLASHBACK DATABASE on major sites and relief and set a RESTORE POINT before the migration of the applications.

  If you stop to redo expedition to the France, the waking state is the last SNA that was applied (i.e. 1001). If you need to return the primary SNA 1011 and then resume the delivery of roll forward, Eve can continue to 1002 from totally ignorant.  If you flashback primary to a SNA lower, say, 998, you would have to flashback the night before as well (997 or 998) until you can resume redo expedition to the France.

• 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).
  
  Concerning

  You can get the list of prices of http://www.oracle.com/corporate/pricing

  However, actual prices depends on corporate discount - which vary according to the customer.

• Mixed version Clusterware in Data Guard configuration

  I currently have a primary database RAC with physical relief RAC database with the database to 10.2.0.4 and Clusterware versions. I intend to move the entire stack to 11 GR 2 finally. My window of failure is limited, I plan on upgrading the Clusterware to 11.2.0.1.2 in a breakdown and the database in a second failure.
  
  To mitigate risk, I plan on upgrading the physical relief of Clusterware cluster version before the main cluster. This will give me confidence and timing to repeat on the main cluster.
  
  The resulting configuration will be: -.
  
  Main cluster: -.
  10.2 Clusterware/ASM/listener
  10.2 database
  
  Cluster relief: -.
  Clusterware/ASM/listener 11.2
  10.2 database
  
  Can you see any problems with this please? Other that a process of LNS 10.2 on the principal should communicate with a listener 11.2 (RFS process), I don't see why it wouldn't work.

  In general, it should not any matter having a rescue system with different version of ASM and GI, since this has nothing to do with what needs the Data Guard. Your hope is so correct.

  However, there are some problems with the 10.2 clusterware 11 GR 2 and databases:

  Please check the MOS score: 948456,1 pre 11.2 questions Database 11 GR 2 Infrastructure grid environment

  As you can see in this note, this unfortunately requires patches in 10.2 as well House...

  In addition, take care if your third disc with voting rights is based NFS. It is best to remove it before upgrading clusterware (has had a problem with that).
  Also if you have some VIPs created for your own applications (not the VIP of the oracle, they are o.k. delete them.) I've heard talk about problem trying to upgrade a cluster containing self creates some VIPs.

  Good luck. And if you encounter problems during the update let me know...

• Satellite A300 - how to restore the system without data loss partition?

  Hi all

  My Satellite a * 3 partitions hard drive * as in Photo

  In the E: partition it is a hiddn folder named "* hddrecovery * ' with a lot of files and a redame file (.html) warns:
  * "HDD Recovery folder *"
  * WARNING! *
  * Do not remove or edit these files and folders.*
  * Any modification may damage the HARD drive recovery system! "*

  The last time I did system recovery using the 2 DVD (created when you first start), it was also * removed the 'D:' partition with all data files *. I'm very disappointed to lose data :_|
  Suggest me _how to make safe system restore to factory state_ * without affecting the secondary partition and its files *.

  Thank you very much.

  Hello

  AFAIK, restore (F8) image of HDD factory settings will delete all data on the C: drive. Using recovery disks it will delete all data on the local local c and D: (hard disk image file creation). If you have some important data moving to device drives or dvd external usb for all cases. That's all I can suggest

• Restore the partition table data

  Hello
  
  
  DB 10.2.0.1
  
  I have a dump file in which exported the data from a table to a database. This table is based partioned. I have imported into the database B. I have truncated or tried successively to the partition of the table in database B now I want to import the data from the export dump file in the same table. I don't want to import the data again for all partitions. I want to just import only truncated how data I could do?
  
  Thank you

  Hello

  Even I did as you say, but we give below error.

  In fact, it is not an error message:

  Import completed successfully without warnings.

  You have SQL code contained in the "dump":

  CREATE TABLE 'TRADING_TEST' ("BRAND_DESCRIPTION' VARCHAR2 (120)...)

  For example, you may notice that importation will try to recreate the Table of TRADING_TEST with all its partitions. Of course, it will generate an error and you will not be able to import the data in the Partition. Unless you have just TRUNCATE and you use the parameter IGNORE = Y.

  So, if you TRUNCATE the Partition you do not have to recreate.

  If you DROP the Partition, it is best to recreate first (ALTER TABLE ADD PARTITION...).

  Then import you the datas like that (I just add IGNORE and LOG settings):

  imp system/password file=C:\exportTable32\table.dmp FROMUSER=dev touser=system tables=(TRADING_TEST:A15) ignore=y log=C:\exportTable32\table.log
  

  However, I hope that it is just for test purpose, because it is not recommended to create the user Tables in the SYSTEM.

  Hope this helps.

• 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.

• Mrp for RAC RAC Data guard configuration configuration

  Grid infrastructure: 11.2.0.4

  DB version: 11.2.0.4

  OS: RHEL 6.5

  Never configured dataguard to the prior CFR.

  We have a production of 3 CARS DB nodes and we plan to implement a physical standby 3-node DB with real-time applies for this prod DB.

  

  In a RAC database, we can only configure one mrp on the side waiting. Thus, apart from the day before, we decided to use Node3 to run MRP. We send redo all instances as stated above on the primary side

  Configuration side Step1.Primary

  Thus, in the all 3 instances of primary DB, we will configure LOG_ARCHIVE_DEST_2 as follows.

  Again all 3 instances should now point to Instance3 Node3 break-in:

  ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 = 'service =acmsprd_dr0_tns delay LGWR SYNC AFFIRM = 0 DB_UNIQUE_NAME = acmsprd_dr0 VALID_FOR = (primary_role, online_logfile)' scope = both;

  Where acmsprd_dr0_tns is the following entry of TNS. As you can see, this name TNS tip to the side instance3 ensures

  acmsprd_dr0_tns =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = yrmst197 - vip3.apac.strcld)(PORT = 1521) .net)

  )

  (CONNECT_DATA =

  (SERVICE_NAME = acmsprd)

  (INSTANCE_NAME = acmsprd_dr03)

  )

  )

  Configuration of Step2.Standby side:

  Instance3 side Eve in Node3 in, start the MRP with real time apply

  sqlplus / as sysdba

  bootable media;

  change the database recovery managed standby database using the current log file disconnect;

  Nothing wrong with my steps above? Is there anything else I should do with respect to mrp?

  Thus, apart from the day before, the RFS process in each node will apply again he received primary for SRls independently to know if the mrp runs in this node. Right?

  Incorrect answer. RFS does not apply again as you said. RFS receives that again. However, RFS on all standby nodes can receive redo of any process of LNS on any node of the primary.

  It is the MRP which makes it apply, no RFS.

  Hi Brian,.

  You said

  "It is not necessary to attribute a SRL to a specific thread. This means that it is possible (and this is how I set up my backup RAC databases) for a SRL be used by any instance, no thread. »

  When you configure dataguard RAC DBs Eve (or primary DBs), add you the newspapers of recovery sleep without THREAD clause as below?

  alter database add standby logfile Group 1 ('+ ORL_DG1', '+ ORL_DG2') size 500M;

  alter database add standby logfile Group 2 ('+ ORL_DG1', '+ ORL_DG2') size 500M;

  alter database add standby logfile group 3 ('+ ORL_DG1', '+ ORL_DG2') size 500M;

  I dot does not specify a thread when creating my SRls. There is no reason to do so. Just that if you have X son of your primary and each thread has groups of newspapers make there, and then create of X * Y SRL in the day before.

  While you create the SRls, remember to create in primary school as well. You'll want them at the primary level to support the transition to the future operations.

  If this is the case, in any node Eve RFS can apply again to roll forward pending any newspaper in the standby database. Right?

  Often when people have discussions like this, it hurts ensure us that we are semantically correct otherwise, we can easily get confusing terms...

  In this case, RFS can write to any SRL, since they won't be assigned to a specific thread. And the SRL is not written in alternating as the ORLs. Then you can definitely see some of the SRL files never get used if you don't have enough flow to make to justify.

  I stay away from the term applies when the MRI because apply is that means MRP. Terms of mixing can sometimes lead to confusion on the road, that's why I would make sure to use the term appropriate to the discussion at hand. I started this answer indicating that RFS is not the 'applies' because of the way the term should be used. That I get to this part of your last post, I see that maybe we get mixed up words that's why I wanted to sort them.

  See you soon,.

• Could not restore the data on the iPad

  Welcome!

  I restarted my data and the news of the iPad in Factory mode and after that I wanted to restore the data from backup to iCloud.

  My problem is very simple.

  After the nice tutorial and connection with apple ID, I have to choose 'restore data for icloud.

  That's what I do every time.

  Next step is to choose which backup I want to restore, I chose iPad Mini 20 June 2016.

  iPad show me to connect to another identifier apple to download applications and...

  He begin to calculate how long it will restore the data.

  It is the calculation for a long time and I can see the end of it. AFTER THAT I decided to stop the calculation, I chose again restore the same backup data.

  After that... it shows me that he cannot restore data from this archive.

  I did it many times, restart, save trying to itunes and nothing does.

  Dr. Fone wondershare cost a lot, and I can't buy it right now. How to restore the data, what can I do?

  FACT.

  I did it.

  I thank all of you who is interested in the topic.

  I like to say how I solved it if someone goes here in the future

  Hi Juliet,.

  Thanks for posting your question on the Forums of community of Microsoft.

  From your problem description, I understand that you need to remove the pop-up date guard appearing every time that you press the mouse button.

  1. are you referring to the date upward when the charms bar arises?

  You can't completely remove the date pop-up Windows 8. I suggest you reduce the sensitivity of the touchpad and check if that helps

  a. press the Windows key + X, and then select Control Panel.
  b. double-click the mouse icon.
  c. properties of the mouse select device settings.
  d. click settings. Select "Properties".
  e. expand the option "sensitivity."
  f. click on the option titled "touch sensitivity.
  g. reduce tactile sensitivity in moving the slider to the right, to the label of "heavy touch. Experiment with different levels of sensitivity until find you one suited to your needs

  It will be useful.
