• Parameters must set up Data Guard with Data Guard Broker

  Hi gurus,
  
  I am following this guide http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf, but it does not specify what settings must be defined for the service to the top.
  
  I noticed that we can set upwards of two ways, either Oracle Enterprise Manager or Data Guard Broker. Do we need to configure the same settings in OEM and after to activate the DGMGRL?
  
  Can you help me?
  
  Thank you

  Denis;

  Yes. Check my example here:

  http://www.Visi.com/~mseberg/Data_Guard_Listener_Example.html

  COMMUNITY is what could be an earlier version.

  Yes, the old version. :

  http://docs.Oracle.com/CD/A57673_01/doc/net/doc/NWUS233/APB.htm

  It worries me because my files are very different and I'm afraid that mix in mine will break your further. The link you posted seems good similar to my settings, but I do not read very good Spanish.

  Best regards

• Additional logging with Oracle 10 g 2 streams and Data Guard

  Hello
  
  I have a physical environment with DB Oracle 10 g 2 and Standby with Data Guard DR CONF. At the present time, this environment will be extended to a pattern of replication using 2-way Oracle Streams Replication (for replication to the central office of this branch, other channels will be added soon). The primary DB is replicated to the other primary DB (at the telephone exchange remotely).
  
  So, there's my question: it is completely necessary to specify an additional record on data sources (primary) to set the 2-way Streams replication? and, if it is completely necessary, then, can configure additional connection on primary without affecting their physical Standby, or what I have to do something special?
  
  Thanks in advance.

  Yes, for the streams you need additional registration. There is no impact on databases physical standby.

• Purge logs archiving on things primary and Standby and for Data Guard RMAN

  
  Hi, I saw a couple of orders in regard to the purge archive records in a Data Guard configuration.

  Set UP the STRATEGY of SUPPRESSION of ARCHIVE to SHIPPED to All RELIEF;

  Set UP the STRATEGY of ARCHIVELOG DELETION to APPLIED on All RELIEF;

  Q1. The above only removes logs archiving to the primary or primary and Standby?

  Q2. If deletions above archive logs on the primary, is it really remove them (immediately) or does the FRA to delete if space is needed?

  I also saw

  CONFIGURE ARCHIVELOG DELETION POLICY TO SAVED;

  Q3. That what precedes, and once again it is something that you re primary side?

  I saw the following advice in the manual of Concepts of data protection & Admin

  Configure the DB_UNIQUE_NAME in RMAN for each database (primary and Standby) so RMAN can connect remotely to him

  Q4. Why would I want my primary ro connect to the RMAN Repository (I use the local control file) of the standby? (is this for me to say define RMAN configuration settings in the Standby) manual

  Q5. Should I only work with the RMAN Repository on the primary or should I be also in things in the deposits of RMAN (i.e. control files) of the standby?

  Q6. If I am (usually mounted but not open) Physics, of standby I able to connect to its own local repository for RMAN (i.e. control based on files) while sleep mode is just mounted?

  Q7. Similiarly if I have an old lofgical (i.e. effectively read-only), to even connect to the local RMAN Repository of Eve?

  Q8. What is the most common way to schedule a RMAN backup to such an environment? example cron, planner of the OEM, DBMS_SCHEDULER? MY instinct is cron script as Planner OEM requires running the OEM service and DBMS_SCHEDULER requires the data runs?

  Any idea greatly appreciated,

  Jim

  The above only removes logs archiving to the primary or primary and Standby?

  When CONFIGURE you a deletion policy, the configuration applies to all destinations archive

  including the flash recovery area. BACKUP - ENTRY DELETE and DELETE - ARCHIVELOG obey this configuration, like the flash recovery area.

  You can also CONFIGURE an archived redo log political suppression that newspapers are eligible for deletion only after being applied to or transferred to database backup destinations.

  If deletions above archive logs on the primary, is it really remove them (immediately) or does the FRA to delete if space is needed?

  Its a configuration, it will not erase by itself.

  If you want to use FRA for the automatic removal of the archivelogs on a database of physical before you do this:

  1. make sure that DB_RECOVERY_FILE_DEST is set to FRA - view parameter DB_RECOVERY_FILE_DEST - and - setting DB_RECOVERY_FILE_DEST_SIZE

  2. do you have political RMAN primary and Standby set - CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON ALL STANDBY;

  If you want to keep archives more you can control how long keep logs by adjusting the size of the FRA

  Great example:

  http://emrebaransel.blogspot.com/2009/03/delete-applied-archivelogs-on-standby.html

  All Oracle is worth a peek here:

  http://emrebaransel.blogspot.com/

  That what precedes, and once again it is something that you re primary side?

  I would never use it. I always had it put it this way:

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

  I would use only 'BACKED UP' for the data protection system. Usually it tell oracle how many times to back up before removing.

  Why would I want my primary ro connect to the RMAN Repository?

  Because if you break down, you want to be able to backup there, too.

  Also if it remains idle for awhile you want.

  Should I only work with the RMAN Repository on the primary or should I be also in things in the deposits of RMAN (i.e. control files) of the standby?

  Always use a database of catalog RMAN with Data Guard.

  If I am (usually mounted but not open) Physics, of standby I able to connect to its own local repository for RMAN (i.e. control based on files) while sleep mode is just mounted?

  Same answer as 5, use a catalog database.

  Similiarly if I have an old lofgical (i.e. effectively read-only), to even connect to the local RMAN Repository of Eve?

  Same answer as 5, use a catalog database.

  What is the most common way to schedule a RMAN backup to such an environment? example cron, planner of the OEM, DBMS_SCHEDULER? MY instinct is cron script as Planner OEM requires running the OEM service and DBMS_SCHEDULER requires the data runs?

  I think cron is still, but they all work. I like cron because the database has a problem at work always reports its results.

  Summary

  Always use a database with RMAN catalog.

  Always use CRF with RMAN.

  Always set the deletion «To APPLY ON ALL STANDBY» policy

  DB_RECOVERY_FILE_DEST_SIZE determines how long to keep the archives with this configuration.

• Data Guard environment, how time will need to use standby Database

  Dear experts,

  (1) when the database is harnessed for how long take use waiting for database so immediately or a few minutes?

  (2) when the server went down how long then to connect with the server backup immediately or a few minutes?

  I'm new to the data protection environment. Kindly help me

  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.

  Quick start failover takes less time. Time will depend on the material, etc. of configuration options.

• Reader only a physical standby Clock Data Guard?

  Hi all

  We try to use TimesTen 11.2.2.4.1 as a memory cache read-only for a 11.2.3.0.7 on Linus RedHat 6.3 Oracle schema, all using Oracle Data Guard to replicate the Oracle instance through geographically remote sites. At each site, we would like to have two instances of TT, synchronization with the local instance of Oracle 11 g. It works very well against the master DB, but TT agents will be able to synchronize against physical standby instances?

  The problem, seems, is that the agent of TT uses structures dedicated in the master Oracle (related to the grid of cache), instance that will be replicated to instances of Eve. Is TT agent able to use the read-only, structures to complete replication synchronization, or is this unworkable approach? What would be your advisor as a way to do this?

  Thanks for your help,

  Chris

  No, I'm afraid that will not work and is not supported. We support the use of groups of READONLY and AWT cache in collaboration with Data Guard in the following configuration (documented in the Guide of Cache TimesTen IMDB):

  1 data Guard is configured as synchronous physical standby

  2. all the caches of TT run against Oracle DB

  3. in the event of a failover of Data Guard, TT hiding can be migrated to run against the DB who now has beed promoted active to standby

  It is the only supported configuration.

  Kind regards

• Archive Data Guard and Flashback

  If I put a few tables to be in the flashback data archive, (support for FDA tables) will be copied to a db as well sleep?
  
  concerning

  Hello;

  I hesitate to answer because you don't seem to close your old questions or give points to those who help. But I also believe in giving the benefit of the doubt.

  If the FIU is configured on your watch then the answer is Yes.

  While this is not a requirement to use I would always use FRA with Data Guard.

  db_recovery_file_dest = ' / u01/app/oracle/flash_recovery_area.

  The following are some sample parameter values that might be used to configure a physical standby database to archive its standby redo log to the fast recovery area:
  
  LOG_ARCHIVE_DEST_2 = 'LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(STANDBY_LOGFILE,STANDBY_ROLE)' LOG_ARCHIVE_DEST_STATE_2=ENABLE

• Data Guard and EHCC on Exadata - does work?

  Exadata Hybrid columnar Compression (OHCC) works when a database is in mode "force logging?
  
  I fear that it may not work because OHCC works only for inserts in direct mode, which means me no logging.
  
  We are in the process of purchasing a vault Exadata, a second target Data Guard.
  
  V11.2 documentation Data Guard is specifically stated that Data Guard doesn't support hybrid columnar compression, but I don't know what are the implications of this.
  
  I expect to have to solve the primary database Machine for 'forcing logging' Data Guard will be used.

  DataGuard physical or logical?

  Oracle fully supports data Guard physical standby and hybrid columnar Compression on Exadata.

  Direct support issues that may exist with Data Guard logic and therefore, at least at the present time, logic is not supported.

  The above is to the best of my knowledge that I don't have access to the documentation of the Exadata. But was certainly true of my
  last experience of HCC. Your Oracle sales representative should be able to provide the definitive answer quickly and I would be grateful
  post you here.

• How to use Data Guard with E-Business Suite

  Hello

  I'm trying to get my head around how would you use Data Guard with E - Business Suite.

  I know that you can use only physical standby with EBS, however I have a few basic questions about specific values < SETTING > and how they are treated by a standby.

  Given that the standby and primary servers will have different host names and that generally there are < FRAME > specific values that include the hostname, where they will have to change on the standby server, both from the point of view of the battery backup Apps and within the standby database itself, I wondered how it would happen.

  Usually, EBS cloning process would change the < FRAME > target settings in the target apps stack and the target database (for example, parameters such as FND_NODES etc.).

  Q1. However I do not know how the process of cloning E - Biz would fit with a database of the day before?

  Q2. As the standby database won't even be in an open State, I don't know yet how you would apply a party any of the cloning process to a database of pending to the target?

  Q3. Even if you were able to change on the eve of the database to reflect the < FRAME > from backup server, it would mean surely it was more a physical copy of the primary database, that's why it would be more a day before.

  All a bit confusing - any clarification appreciated

• How to Setup Data Guard with alter tablespace... begin backup approach

  Hello!
  
  I am writing this compilation of documents in a guard daata establishing in 10g. I was in charge to present different approaches in implementing on Rhel 5.
  
  I came across 3 procedures (which is to duplicate a database with RMAN, then configure it to a Data Guard feature). I read a process using (let's this is what the article said, but procedure was presented):
  
  alter tablespace... .begin backup;
  alter tablespace... .end backup;
  
  then copy the generated files and configure it to the data protection feature.
  
  Someone help it with that? Is there like a blogsite or steps I can take for this scenario?

  Hello;

  The best I found was: (and its same 10 Oracle! and not RMAN.)

  http://sites.Google.com/site/catchdba/physical-standby-database-using-HOTBackup

  There, an old link here on this topic:

  DataGuard configuration using hot backup files

  Hard to find much on this topic as "Hot Backup" almost always comes to RMAN.

  This collection of notes can also help:

  DataGuard knowledge browser Product Page [ID 267955.1]

  And the "Formidable" Powerpoint:

  www.dbspecialists.com/files/presentations/standbydb.ppt

  Seems that this method is dead somewhere between Oracle 8 and Oracle 9

  If I do all passage between and B , now that b is primary and remaining has and C are pending data bases. At this point also, Archives of the newspapers should move from B to A and B to C. In addition, even should arrive from C to A and C to B, if I make the passage between B and C. If all goes well, then I'll do switchback to the main database (A) primary.

• Oracle Data Guard with EBS R12

  Dear gurus,
  
  I want to know about Oracle Data Guard with Oracle EBS Release 12, claims we separate license with Oracle E-Business Suite R12 of application Data Guard? (i.e. separate premises, same place).
  
  
  Please me advice in this regard.

  AFAIK, you don't need to have a separate license for Data Guard. However, I would say that you call your Oracle representative.

• 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).

• Using Oracle 11 g Data Guard disaster recovery

  Hi, can anyone answer if Oracle 11 g Data Guard by itself provides an option for making/switch between the main bases and emergency (back and forth) disaster and as a restoration solution, seamlessly? Here's the scenario:

  1. two databases (active and reserve)

  2 put it to sleep (make primary with read/write)

  3. restore to the original database

  Data Guard has two transitions of role... Failover and the digital switchover.

  Passage to the fact exactly what you describe. You can switch to standby and vice versa. However, this will not work unless the primary and the standby are available. If you will not be able to perform an operation of swichover when you have a failure in the main data center that makes the primary db not available.

  Failover will be the day before in a primary for the moments where the primary origin is not available. Unlike the digital switchover, failover is one-way. There is no 'restoration' of failover. If you do not failover, then once the old Center of main data is operational again and you can get the former primary database up, you must restore from the first news and make a watch for the first new. At this point, you can then make a pass to come back and run in the original data center.

  HTH,

  Brian
