• Insert into a primary database of Eve Active Data Guard

  I use Oracle EE 11.2.0.3.8 on Solaris 10.

  I read that it is possible to do an insert in my database for the standby Active Data Guard by redirecting the insert to get on the primary via DB link.  I GLOBAL_NAMES set to TRUE and he needs to stay that way.  This means that I can't create a DB link pointing to my first as such:

  CREATE DATABASE LINK PROD. WORLD WITH THE HELP OF "PROD_PRIM";

  How can I get around this in order to insert data in my standby ADG primary?

  Hello;

  There is an article about it here by Uwe Hesse:

  http://uhesse.files.WordPress.com/2012/03/realtimequery.PDF

  I understand that if GLOBAL_NAMES is true, then, the database link must have the same name as the database in which it connects.

• Enable and disable Active Data Guard

  We are to build a simple primary (no CARS) to the physical environment pending (no CARS) Data Guard.
  Build us local and then shipment to the customer.
  During our generation we load data and the physical database in Active Data Guard 'mode '.
  To make it easier to check that the data is "protected".
  
  How to get back to "regular" managed recovery Active Data Guard "mode"?
  We were closing the physical Standby and then reopen in managed recovery "ordinary."
  Is it possible to do WITHOUT closing the physical Standby?

  N ° the only way is at the stop of the physics of the day before and then do a START-UP SUPPORT and restart the application. What version do you use?

• Active data guard lost synchronization

  Hi guys,.

  I hope you can give me some advice.

  I have a BD PRIMARY in a server and a STANDBY in another server.

  I do not configure these databases and I don't have too much experience with data protection.

  The problem is that the STAND BY lost the sincronization. I just watched a few views on the database and I found that the media database is READ only, so I think that is an Active Data Guard.

  -PRIMARY:

  SQL > SELECT name, State, database_role, open_mode connections, log_mode FROM v$ instance, v$ database;

  STATUS DATABASE_ROLE LOG_MODE CONNECTIONS

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

  BD PRIMARY READ WRITE ARCHIVELOG

  -STANDBY TIME:

  SQL > SELECT name, State, database_role, open_mode connections, log_mode FROM v$ instance, v$ database;

  STATUS DATABASE_ROLE LOG_MODE CONNECTIONS

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

  PHYSICAL STANDBY BD READ ONLY WITH APPLY ARCHIVELOG

  
  

  -PRIMARY:

  "SQL > select SEQUENCE #, FIRST_TIME NEXT_TIME, APPLIED, ARCHIVES of V$ ARCHIVED_LOG, whose name = ' STANDBY' FIRST_TIME agenda;

  
  

  SEQUENCE # FIRST_TI ARC APPLIED NEXT_TIM

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

  426 13/05/15 13/05/15 NO YES

  427 13/05/15 13/05/15 NO YES

  428 13/05/15 13/05/15 NO YES

  429 13/05/15 05/14/15 NO YES

  430 14/05/15 05/15/15 NO YES

  I saw the newspaper archive all copy them correctly on the standby server, but they apply. I don't know why.

  How can I get the two database will be synchronized? What option I have?

  Best regards...

  Hello, you should check if Fal_server and Fal_client settings are configured in the main bodies and relief.

  In the standby instance fal_server must point to name PRIMARY, as it appears in tnsnames.ora

  fal_client must point in standby mode, as it appears in tnsnames.ora

  In the first instance, fal_server must point to the name of Eve, as it appears in tnsnames.ora, fal_client pointing to primary name, as it appears in tnsnames.ora

  on the other hand, you must restore the automatic sequence 33-55 on the backend and fal then transport and then primary eve because of the resolution of the gap.

• Grid d? infrastructure is needed for Active Data Guard fast failover?

  Hello

  I'm currently deploying an Active Data Guard of 11 GR 2 configuration with a captain and two slaves physical standby and failover accelerated for a Java JDBC application. Each instance has a read-only service that is always active and a service of reading / writing that is activated only on the master:

  srvctl add service -d smsgsig1 -s smsgro -l PRIMARY,PHYSICAL_STANDBY -e NONE -m NONE
  srvctl add service -d smsgsig1 -s smsgrw -l PRIMARY -e SELECT -m BASIC -w 10 -z 150
  

  Initially, I had planned to use the Service of Notification of Oracle (ONS) to notify the application in case of change of master, that works, however, after a few tests, it seems that simply leave the retry request enough times in the case of a connection failure is sufficient to re-connect to the new master afterwards, in order to complete any pending transaction.

  So my question is: since I plan not to use ADD-ONS, do I have the grid infrastructure and Oracle Restart at all to deploy Active Data Guard? The documentation does not explicitly require it, and all the necessary tools, including srvctl, exist in the plain 11 GR 2 home. However the mechanism of activation/deactivation of the service will work without restart? To be honest, I don't think it would be, but that this would simplify the deployment, a little, I thought it would be good to ask :-)

  Thank you for your understanding,

  Chris

  Hello;

  The simple answer is no, I could consider changing my order srvctl.

  EI SESSION (type switching must be set to both)

  m BASIC (set on both)

  l PHYSICAL_STANDBY (isn't one of yours in this service role?)
  z - 15 (150 retrys seems too high)

  q (the value TRUE or FALSE)

  w (set on both)

  srvctl add service d smsgsig1 s smsgro-l PRIMARY - SESSION - q TRUE m BASE w 10 EZ 15

  srvctl add service d smsgsig1 s smsgrw-l PHYSICAL_STANDBY - q REAL - m BASE w 10 EZ 15 SESSION

• Digital switchover and Active Data Guard

  I spin a quarter-Exadata V2 support systems (two instances CARS) and am changing my sleep Physics (an Exadata V1 rack with four RAC instances) in an Active Data Guard configuration (i.e. bearer Real - Time Query). The RDBMS runs 11.2.0.2 with BP7.
  
  My question is if I need to disable RTQ/Active Data Guard before a planned failover? If this is not the case, the transition process will automatically start QTR on the 'new' standby (i.e. my 'old' primary)? We'll test this on next month, but he was curious to know what to expect in advance.
  
  I use DGMGRL (Data Guard Broker) to manage the transition to digital.
  
  Any thoughts?
  
  Mark

  If you use the broker, as you must do with RAC, the broker must manage everything seamlessly. If it's not, and you need to test this, open an SR with Oracle's Support.

• Fast-Start Failover & Active Data Guard

  Hi experts,
  
  I set up a 2-nodes with fast failover-Dataguard!
  
  While tesing the system I have seen that the backup database is to read only State (no editing).
  
  It means I have a watch guard of active data!
  
  Active data guard standby is a necessary condition to run the accelerated shift (the license is required?)
  
  Thanks and greetings
  
  hqt200475

  To be more precise: READING ONLY one OPEN does not mean that you use queries in real-time, who need the option Active Data Guard. Only if you redo apply while being read-only that is open has Active Data Guard. You can determine by the column OPEN_MODE from v$ database with11.2.

  Kind regards

• Active Data Guard and Undo and ora-01555

  Hello
  
  We have a 11.1.0.7 two nodes primary CARS with a physical standby single instance Active Data Guard. When you run an export datapump since the day before, we get an ORA-01555 while the undo_retention is well beyond the duration of watering for export.
  
  I'm looking to better understand the cancellation as part of Active Data Guard. Is there any dependency for cancellation between the primary (s) and the day before? Are the settings Cancel (undo_retention, tablespace... undo size) on the primary and independent intelligence on the other?
  
  Thank you.

  The wait is a physical expectation. An exact copy of the primary. The cancellation to sleep is controlled by it again come from the primary. When the cancellation is replaced in the primary, he gets crushed to the standby regardless of what it executes. You cannot cancel maintained around more on the eve, it is a replica of the primary.

  Increasing the undo tablespace and the primary undo_retention allows more Cancel to keep both primary and standby, but Eve is always controlled by the direction of the primary to cancel it. Of course, you must change the setting to sleep too so that everything is the same when you made the day before to a primary database.

  I hope this helps.

• RMAN 11g Active Data Guard

  I just built my first Active Data Guard 11g... Well, the next thing to do is the RMAN part.
  At this point, I want to know:
  (A) Comment / what you ask that a newspaper has been applied on the side of the eve
  (B) how RMAN knows what has been applied
  (C) if I do the RMAN backup side the day before, won't be there always some difference because there is always some delay between the primary and Standby?

  I assume you mean with RMAN to delete the archive logs? If the newspaper was not delivered and applied to the day before still wont RMAN delete, instead, it displays the following error:

  RMAN-08137: WARNING: log archiving not deleted because it is still necessary

  Until the newspaper has been applied on the eve, this intelligence is built in to 11G (10 g you need a parameter of '_' to get this to work).

  Thank you

• Data Guard versus Active Data Guard?

  Environment:
  
  Oracle on Solaris 5.10 EA 11.2.0.3 database
  
  I have read several threads here and paid through the documentation, but this point still escapes me.
  
  When Data Guard to become Active Data Guard?
  
  When Eve is OPEN and in read mode ONLY all redo logs are actively applied?
  
  If I stop log apply and OPEN the day before for READONLY access, is this just regular Data Guard?
  
  I want to of course use Data Guard but not pay for Active Data Guard at this stage.
  
  Where this is documented?
  
  Michael, if you listen, it's well to the top of your driveway! :-)

• OIM 11 g database using Active Data Guard recovery

  Hello
  
  Someone did he do IOM database failover configuration using the active data guard.
  
  Here are the details
  • Two application in primary servers and one in secondary sites
  • Two databases one in primary and the secondary sites.
  • Two application servers point to the primary database.
  • There is an Active Data Guard set up between primary and secondary data.
  • Secondary database is in stand-by mode.
  • Unique CNAME is configured and actively points to the primary database.
  • Failover of the database, the principal is down and the secondary database is marketed as primary and CNAME is changed to point to the secondary database.
  • All the data sources in Weblogic are configured to use CNAME.
  
  The problem here is the SID. In the primary, we have JSQOIM1P and in the secondary, the SID is JSQOIMDR.
  
  So when we switch the error we get is unknown TNS name like Weblogic data sources don't know the JSQOIMDR.
  
  How do configure us the failover in this scenario?
  
  Thank you

  Hello

  I was able to achieve this by setting up a unique service name pointing to the primary db SID and the same name of unique service on the secondary db pointing to the db secondary sid.

  For the benefit of the users of the forum.
  CNAME - usoimdb pointing to primaryDBHost and can be changed to secondaryDBHost in the case of DR

• Active Data Guard on DB 11 g and ADF business components

  Does anyone has experiences using business against a data source Active Data Guard components? Y at - it something ADF BC specific, you might need to know/set up regarding the parameters of the Application Module. Of course, we would read only your with her. Sorry it kinda turns out to be a beautiful finished question just want to know if it's a go or one thing more than any other possiblity.

  TheOtherDave,

  It should work perfectly. One thing you will need to know is the passivation of State mechanism used by ADF BC can use a store based on files or DB-table-based store. Obviously, if you want to use the DB-table-based store, you will have to configure it to point to a database where you can write to DB tables, which will be probably different from your database pending of DG. Otherwise, I can't think of specific issues (but I don't him have not personally tested).
