• Oracle 10g RAC + ASM + Data Guard: Question on the new disk group.

  Hello
  
  One of our clients is to have Oracle 10 g RAC + ASM + Data Guard. Database is the disk DATA_DG1 group and FRA is on FLASH_DG1. Data Guard is a single instance on ASM.
  
  To add more space, we can create another disc of the Group DATA_DG2 on Prod ASM and Data Guard ASM env, replication continues without any problem. Will be archiving logs shipped to the second disk DATA_DG2 group and applied without any configuration changes?
  
  Rgds,

  Yes, it sounds great.

  You should be fine with the implementation of these measures and the dataguard should continue on as usual.

  Just make sure that you are dealing with a physical standby that has not the conerts file name defined.

• RAC and Data Guard

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; the backup site must be in configuration CARS as well, or can it be a stand alone configuration?

  Hey Buddy,

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; > the backup site must be in configuration CARS as well or can it be a stand alone configuration?

  No, it is not mandatory. You can set up a watch using one instance and the database with the help of a RAC. as well as the opposite.

  For example, I've already migrated a RAC to a single instance, using stand-by. Rather than perform a failover, we performed a switchove, then the database primary was a single instance and the day before by a RAC database.

  It will be useful,

• When creating Data Guard?

  We intend to migrate a database RAC and Data Guard.
  
  When you recommend implementation of custody of data? Before the export/import (from the old server to new CARS in custody of data) or after?

  You must first configure your new primary CARS and then configure the standby of the CARS (after the imp on the primary).
  This way you avoid the mass mailing to redo the expectation that comes with the PMI, if this sequence of steps will be faster.

  Disadvantage: If you take the primary CARS into production immediately after importation, there will be a short period of time without protection in this way DR.

• Data Guard CARS

  Hello
  is there a special configuration or guidelines to the configuration data guard on an Oracle cluster database, or as the only forum?
  Thank you very much

  Hello

  Do you want to say that each instance on a cluster to own his own spfile, and I need to change each separately spfile to redo waiting for shipment?

  All cluster database instances must use the same shared spfile... You can also change the spfile... you will have to update using the command:
  alter system set parametername = value scope = spfile sid = InstanceName

  My second question is that each instance generates its own recovery logs to archive, so should not be that database waiting to be ordered into clusters, no? It will applied logs coming recovery for any instance of cluster, is that correct? even if it's only one not clustered instance Eve...

  You can have a single instance watch and all the newspapers all primary levels will apply to it...

• 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...

• 11g R2 RAC OneNode vs Active Data Guard

  Hello
  
  I just read on the new Oracle RAC one node but ddont get the difference to the active data guard.
  
  "RAC OneNode offers another possibility: an additional way to fight against the consolidation with one instance of RAC running on a node in a cluster." Oracle calls its strategy a "Maximum Availability Architecture" - when a customer adds redundancy, the database can use it for additional performance. Active Data Guard allows customers to move backup and redundant reports to the machines. "
  
  Source: http://www.b-eye-network.com/blogs/adrian/archives/2009/11/
  
  maximum availability architecture, is not the custodian of data?

  metalray

  >
  Is it scalability... only. Apart from this. A blog has been linked that says 'Extended RAC'.
  Why should I use RAC for the filesystem of database if they are on a San in any case - assuming the SAN extends to different places? It seems to be that a good SAN makes the idea of 'Extended RAC' a bit useless.
  >

  If you already have a San that "extends to different places", you have protection against disaster with that if you put your data files on it, this is true even for a single instance respectively a one RAC node configuration.

  In both cases, you only have a single instance active - in other words, a single server can be used to service your needs of the user. With a true - in this case 'Extended' CARS, you can have multiple servers at the same time access to your data that is stretched across your San as your needs of the service user.

  In short: If you want to have the only disaster protection, you are served already with your stretched SAN - as long as it extends to a large enough distance.

  An extended RAC is not useless, however, because the cab is more than high availability.

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

  Hi all

• Oracle will produce Certification Exam preparation seminar for ECAS 12 c Perf Tuning, Rac, Data Guard?

  Hello

  Oracle will produce Certification Exam preparation seminar for Oracle 12 c OCÉ Perf Tuning, Rac, Data Guard?

  I took the seminar for RAC and oracle 11 GRID infrastructure certification exam.

  I was wondering if they will ever do this course of preparation for Oracle 12 c for

  * performance (1z0-064)

  * rac and grid infrastructure (1z0-068)

  * Data Guard (1z0-066)

  Thank you Roger

  I don't know if everything is still planned for the creation of the seminars review for these exams. If/when they are released, they will be announced on our blog - blogs.oracle.com/certification.

• Database is configured for Data Guard

  I'm lance a UTF8 conversion on a development database, which has been cloned from Data Guard. There is a warning in the Migration status: "database is configured for Data Guard" which is looking at DMU to determine this? The database is opened in read-write mode and it behaves like a primary database (I have the MISP scanner and run updates to address representations not valid). I would like to know what I need to update the settings.

  This prevent me to convert tables using DEC? When I try to select this option for all tables I get the message, "CDS does not support conversion method"Copy data using CREATE TABLE AS SELECT"for tables that are involved in a process like capture Oracle Streams, or apply.". Another method of conversion available for the table.

  Thank you

  Ben

  CDS checks if the DG_BROKER_START parameter is set to true.

  The problem with the ETG is independent of the Data Guard. The CDS is true for tables which:

  -are asynchronous stream capture source, or

  -update conflict managers have, or

  -DML managers have, or

  -conflict resolution settings have

  The above tables are considered to be configured for Oracle Streams and are not supported by the method of conversion of DEC. This is because the DEC method creates a copy converted the table and falls from the original. The CDS is not able to move the configuration information from the old table to the new flow.

  Thank you

• Several primary and physical databases Configuration ensures in Data Guard Broker

  Hello

  Is it possible to add two or several primary and physical databases configuration ensures in data guard broker?

  I have 1 primary databases and two databases physical standby that is

  (1) primary that is pri - (database primary)

  (2) secondary i, e, s (physical pending)

  (3) Secondary2 i.e. sec2 (physical pending)

  Practical AM sinister place, my scenario is my pri and dry machines are in seat, if the pri crashed it switch to s that works very well and my S2 is in another area office. Suppose that if my two siege machines pri and sec crashed, so I want to do my mahcine sec2 as primary.

  I have two separate computers to the broker a headquarters and a District Office

  Use failure of quick start on Data Guard Broker, broker headquarters machine I have configured pri and dry but in sector office broker not able congifured pri and S2 and the machine.

  can be done several primary database configuration with data bases on hold?

  Has anyone done this before, or has a perform a recovery after loss of place...

  need help or suggestion

  thanx

  No.... It is not possible. When you use the DG broker, the first thing you can do in the DGMGRL utility is to deliver CONFIGURATION to CREATE. You can see on the doc of this command that you define here the PRIMARY DATABASE.

  The command to add a DATABASE to the broker, adds a new database pending. You cannot add an another primary.

  The broker configuration is explicitly for a primary and all standby databases is supported. If you have an another primary, you create a separate DG broker configuration.

  See you soon,.

• 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".

  If you believe that your logs are too big departure "Troubleshooting performance problems with the database and base/MFG MRP [ID 100964.1]"

• 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.

  This command is the full backup or a backup of level 0?

  full backup as compressed backupset
  data include current controlfile more archivelog deletion entry;

  We use command below for the full backup of database.
  database backup incremental level 0 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL0_%D_%M_%Y'
  include current controlfile
  tag 'datafile_full ';

  We use the command below to the increment backup
  database backup incremental level 1 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL1_%D_%M_%Y'
  include current controlfile
  tag 'datafile_Incr ';

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

  or
