• Purge of the archivelogs on primary and Standby

  Hi all

  11.2.0.1

  AIX 6.1

  I'm tracking use of space in our FRA for DG primary and standby. I want all archivelogs purge once they have been applied in standby. Still, what is the use of it?

  I checked google and I found this procedure, will it's okay if this evil?

  Primary:

  =========

  RMAN

  {

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

  }

  On hold:

  ========

  RMAN

  {

  CONFIGURE THE NONE ARCHIVELOG DELETION POLICY;

  }

  
  

  
  

  When I issue the command DELETE NOPROMPT ARCHIVELOGS OBSOLETE?

  
  

  Thank you very much

  Hello

  remove the force archivelog all; Just delete everything he finds little matter whether or not it is necessary. It will remove files that have not been saved and will also remove the files not delivered/applied to forward.

  See you soon,.

• Data Guard - RMAN removing archive log

  Hello

  I ' v DataGuard with physical standby.

  I do a backup only on the primaries. Both sites have ther separate backup systems.

  I ' v FRA and configured archivelog deletion with RMAN configuration:

  on primary: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;

  standby: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;

  It works fine but I think what if scenarios and I'v qestion on best practices for backup after the transition of role management. Let's say that for some reason, as i'v in switch mode sleep for a few days and the backup will be posible to watch (now primary) database. What would be the steps/reconfiguration appropriate to do?

  1 should I reconfigure RMAN?

  change of new primary to: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;

  change back to sleep again: CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON STANDBY;

  2. make full backup

  Hello

  1. you can refer to the oracle documentation: http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmconfb.htm#CHDCFHBG

  section: "all archived Redo Log deletion policy."

  Document provides the best algorithm to analysis of work

  You can use the CONFIGURE ARCHIVELOG DELETION POLICY BACKED UP integer TIMES TO DEVICE TYPE command to allow a policy of removal of archived newspaper. This configuration specifies that archived newspapers are eligible for deletion only when the specified number of archived log backups exist on the specified device type.

  
  

  If the deletion policy is configured with the BACKED UP integer TIMES clause, then a BACKUP ARCHIVELOG , the command copy newspapers, unless integer already exist on the specified device type backups. If integer are backups of logs, then the BACKUP ARCHIVELOG command ignores the newspapers. In this way, the deletion of archived newspaper policy works as a default NOT BACKED UP integer TIMES clause on the BACKUP ARCHIVELOG command. Note that you can override the deletion policy by specifying the FORCE option on the BACKUP command.

  The deletion of archived newspaper policy has also options specific to an environment Data Guard. , then RMAN can delete logs after they have been applied to all destinations remote mandatory. If you specify SHIPPED TO STANDBY , for example, then RMAN can remove log files when they were transferred to all destinations of mandatory relief.

  2. the paper provides good information, just to check and decide easily based on the functionality of the database role you can configure.

  It will be useful.

  I want to configure * 2 Eve * databases for the single primary database.
  Allows to take, A, B and C are my machines. My Data Guard configuration will be like, * archive logs will be mobile * A to B and A to C.
  
  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.
  
  How should I mention PFILE in all machines , parameters like

• 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.

• 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.

  You may need the parameter sql_trace set to true for the level of database tracking.

  But I suspect you may be hitting a bug, suggest you to trigger a SR with Oracle support for more information on the crash of Eve.

• Data Guard archive political deletion log

  Hi all

  I configured the data guard with 2 bases Eve in oracle 11g.

  I want to use rman to delete archives on all servers.

  I have configured no FRA, no recovery catalog.

  My question is:

  If I delete waiting til sequence # 1627 and on primary sequence til = # = 1620 or vice versa this would cause problems for Data Guard.

  I say delete until the different sequences # on primary and standby cause problems for synchronization?

  Thank you

  So if I understand delete archivelog to sysdate - or delete archivelog all completed before sysdate n is not the archivelog deletion policy you put on RMAN?

  She depends on it. The note was made at the base of the MOS document how ensure that RMAN is NOT delete archived logs that have not yet shipped to standby mode (Doc ID 394261.1)

  Delete archivelog to sysdate - depends on all of the deletion policy. If the deletion policy is set on "applied pending all", then it does not delete the archives, if they are not applied on the day before. If the deletion policy is set to none, then it does not check if the archive is applied on the eve and deletes them directly.

  Last Archive generated on primary:

  SYS@oraprim > select max(sequence#) from v$ archived_log;

  MAX(SEQUENCE#)

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

  114

  Last check-in applied in mode ensures:

  SYS@orastb > select max(sequence#) from v$ archived_log in case of application = 'YES ';

  MAX(SEQUENCE#)

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

  109

  Delete policy set to NONE on primary:

  RMAN > show archivelog deletion policy;

  using the control file of the target instead of recovery catalog database

  RMAN settings for database with db_unique_name ORAPRIM are:

  CONFIGURE THE NONE ARCHIVELOG DELETION POLICY;

  RMAN > delete archivelog until 'sysdate;

  allocated channel: ORA_DISK_1

  channel ORA_DISK_1: SID = 60 type of device = DISK

  It checks if the archive has been applied on the day before. As the 110 to 114 sequence is not applied in the waiting, the archives are not deleted on the primary.

  Hope that gives you a clear picture of how it works.

• How to move from Data Guard time really apply (restore) to archive the journal

  Hello
  
  Standby database configured with broker and application really remake in time; However, I want to change it to archive the journal apply mode without losing the broker configuration. Is this possible? If it is not possible to use the broker to make archive log apply, I can remove the broker and use Data Guard to set up the day before to use the archive log apply?
  
  Concerning

  Hello;

  Broker automatically allows real-time applies to databases on hold if the standby database has standby redo logs configured.

  Stop repeat applies

  DGMGRL> EDIT DATABASE 'PRIMARY' SET STATE='APPLY-OFF';
  

  Repeat restart applies broker

  DGMGRL> EDIT DATABASE 'PRIMARY' SET STATE='APPLY-ON';
  

  In order to get rid of standby redo logs would be a way. I would like to leave myself alone. Real time assistance to prevent the loss of data.

• Refresh the MV of standby Active Data Guard

  Is it possible to refresh a materialized view (quick or full) come from a standby database Active Data Guard open in read mode only w/apply?  Or can I just do the update of the primary?

  Hello mseberg,

  You made a very good point about the definition of a database of the READER.

  After you have answered, I found in MOS: create a distributed materialized view based on a master table on a database in read-only (Doc ID 276023.1)

  This explains that it is NOT possible to make a fast refresh of a database shall RO.  However, it *peut* be possible to do a complete refresh of a standby Number.  It depends on the query used to define the MV.  If the RDBMS Analyzer determines the MV is *able* to fast refresh (even if there may not need it right now), so you can't do a full refresh since the eve of the RO.  If the parser determines that the request is NOT able to fast refresh, then you can do a full refresh since the eve of the RO.  I tested this script on 11.2.0.3.8 and found to be true:

  CREATE THE MIMI MATERIALIZED VIEW. MV_TEST

  TABLESPACE USERS

  IMMEDIATE CONSTRUCTION

  COMPLETE REFRESH

  AS (SELECT * FROM TEST@MIMI_ROSTBY);

  ORA-16000: database opened for read-only access

  ORA-06512: at "SYS." DBMS_SNAPSHOT_UTL', line 364

  ORA-06512: at "SYS." DBMS_SNAPSHOT_UTL', line 446

  ORA-06512: at line 1

  Now, I've changed the MV query to use a 'one time' feature (ROWNUM), which causes the query become complex (not able to fast refresh).  I can now create a MV on the day before RO, because the query is no longer able to fast refresh and requires no registration on the eve of the RO:

  CREATE THE MIMI MATERIALIZED VIEW. MV_TEST

  TABLESPACE USERS

  IMMEDIATE CONSTRUCTION

  COMPLETE REFRESH

  AS (SELECT * FROM TEST@MIMI_ROSTBY WHERE ROWNUM > 0);

  Created.

• 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,

  And I really sorry, I want to provide something more.

  '' Waiting, sone entries are with dest_id = 2, they are really initially generated from standby ''?

  Big question. I do not know. Checked: oracle note 241374.1 for details on dest_id without success.

  I think it's that dest_id indicates whether the destination is local or remote. If, if it is true that the answer is no.

  This makes sense since the database is read_only mode, why it would generate archive here?

  If you still have all the archive back to 12-15 then there is still hope.

  However, 12-15 is a long time ago. I consider at least rebuild the day before.

  241374.1 is worth a visit because it can provide additional information for the future.

• Archive purge logs

  Hi all

  EBS R12.2

  OL6.5

  I have the main and backup database. In elementary school when I complete rman backup daily and overlap remove obsolete, old archivelogs are purged.

  But on the side of the day before, I do the same thing but the archivelogs are not purged, that's why I'm getting a disk full problem. Why is it so?

  How to purge the automatic archivelogs at startup of the database?

  Kind regards

  JC

  Hello Jenna.

  Obsolete archives logs/remove purge on primary removes no newspapers to check-in on the day before.

  There are several ways to delete pending archive logs and also many factors must be taken into account, such as how often the destination of archive is maxed out, size of the destination, number of generated archives

  Simply put, you can create a cron job to delete logs archiving to the standby site. Example below, archive logs will be deleted even if they are not applied.

  For example,.

  RMAN target ${TARGET_CONN}

  delete noprompt archivelog all completed before ' sysdate - 1';

  Based on your requirement, you can run the cron one or two times a day and also change the interval of less than 1 day ('sysdate - 1/2 ' or ' sysdate - 1/4 ')

  Hope this helps!

  Kind regards
