Archive Data Guard and Flashback

Similar Questions

• Data Guard and Flashback

  I will be an active data guard with a primary instance and a secondary instance. I'm in the environment no CARS. My primary databases and Eve will be the flashback database on. I duration of blowback for one day, i.e., I should be able to flashback to the top of any time in the last 24 hours.

  When I do the RMAN backup on primary and remove the archiving log by using the rman command, RMA will not remove newspapers to archive that will be required for the flashback database (24 hours a day)?

  When I am applying newspapers archived on the backup site, I want to remove the archived logs that have been applied, but not required for the flashback database. How can I determine that? In the worst case scenario, I can always keep archived logs from 1 day to wait?

  1. Thank you.

  You need not remove the flashback logs.  Oracle automatically manages the removal of flashback logs.

  Configure retention policy to remove the archive logs more at some point.

  Configure archivelog deletion policy to manage the removal of logs that have been applied to the wait.

  for example:

  CONFIGURE RETENTION POLICY TO RECOVERY OF 7-DAY WINDOW;

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

  In the worst case if you discover you need archivelogs that have been removed from the drive, then you can restore them because they have already been backed up by RMAN.

• Data Guard and connectable to database

  Possible to have some project documents in a CDP that is used for Data Guard and other PDB files don't not ITIS?

  No, not in the current version. You must use the PDBs als for DG or nothing.

• Data Guard and auditor of the Apex

  Hi all

  I seem to be unable to understand the configuration of parameters for protective Apex listener when connecting to a database.

  We have a lot of servers of databases (without data guard) and we use the command line Wizard to generate the configuration file. It's straigthforeward and
  easy. We enter the server, port, and Service_name and it works.

  But for a guard database, there are two servers and I seem to be unable to set it in the right way. After doing some research I came across the parameter apex.db.customURL which should solve the problem.

  I removed the references to the server, port, and Service_name and put the key in.

  The result were errors of connection due to some incorrect port settings.

  SEVERE: The pool named: apex is not properly configured, error: IO error: format invalid number for the port number

  oracle.dbtools.common.jdbc.ConnectionPoolException: the pool named: apex is not properly configured, error: IO error: format invalid number for the port number

  at oracle.dbtools.common.jdbc.ConnectionPoolException.badConfiguration(ConnectionPoolException.java:65)

  What Miss me?

  Thank you

  What Miss me?

  You must create two entries in the configuration file "defaults.xml" for your ADR (formerly APEX Listener).

  One for db.connectionType and, secondly, for db.customURL, for example:

  customurl
  jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=
  (ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(HOST=DB-ENDUR)(Port = 1520))
  (ADDRESS=(COMMUNITY=tcp.world)(PROTOCOL=TCP)(HOST=DB-ENDURK)(PORT = 1521))
  (LOAD_BALANCE=off)(FAILOVER=on))(CONNECT_DATA=(SERVICE_NAME=ENDUR_PROD.VERBUND.CO.AT)))
  

  Reference: http://docs.oracle.com/cd/E56351_01/doc.30/e56293/config_file.htm#AELIG7204

  NOTE: After you change the configuration file, don't forget to restart independent ADR / Java EE application server support if ADR is deployed on one.

  Also check if your URL for a JDBC connection is working properly and if there are any questions, you can turn on debugging for ADR:

  Reference:

  • http://docs.Oracle.com/CD/E56351_01/doc.30/e56293/trouble.htm#AELIG7206
  • http://docs.Oracle.com/CD/E56351_01/doc.30/e56293/trouble.htm#AELIG7207

  Directed by Tony, you should post the ADR related questions to the appropriate forum. Reference: ADR, SODA & JSON in the database

  You can also move this thread on the forum of the ADR.

  Kind regards

  How can we know what newspaper Archives are eligible to be removed from 'A' and 'C '?
  When remove it takes place?
  How can say us when archiving logs are deleted from the 'A' and 'C '?

  Dear user10260925,

  The documentation that you read is reliable but not enough.

  The Oracle can handle the archivelog directory and know that you are eligible for deletion. Stuff you posted here was derived from the books online and is supported and can be used when the Oracle knows and manages the archivelogs. This is simply called the flash recovery area. Please read the FRA at this very moment.

  Under the personal component normal circumstances in the industry use a few scripts to achieve on backup archivelog deletion.

  Here's a useful example to you;

  # Remove old archivelogs

• 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.

• 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.

• 12 c database Data Guard and connectable to DR

  Hi all

  I have a database upgrade from 11.2.0.3 to 12.1.0.2 to come. The current set up is the PROD & DR are 11g data protection configuration and it works fine. The two databases are in ASM and the configuration is exactly the same as well PROD & DR sites. The database is currently 25 TB.

  I understand how make the upgrade to 12 c, then let cascading changes through on the DR database - so NON - CBD on both sites. Thinking aloud here, I would plug in the PROD database into a new CBD. I suppose I create a CBD DR and then convert DR pluggable database, modify the dataguard config (as it is at the level of the container in 12 c) and plug into the DR database in the new CBD DR? Then copy the archivelogs of CBD PROD on the DR site to fix gaps. This approach wouldn't work?

  Thoughts everyone?

  Thank you

  Vic010

  OK Oracle confirmed - you must copy the data files to the doctor and then rebuild the database of DR... Is not ideal if your database is 25 to and in full swing. The last time, he had to rebuild the database, it took a week...

• 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".

• Request to license Oracle Data Guard

  Nice day! at all. I don't know if this is already asked before, but I would like to ask for your help regarding my inquiry.
  
  We have an Oracle 10 g Database EE here in our company which is established in a RAC (2 nodes and 1 SAN). Of course, that are already approved.
  
  We intend to implement the Oracle Data Guard.
  
  Of course the Oracle Data Guard will run voluntarily for a disaster recovery, in the case that our CARS (especially the SAN) will crash, we would like to have a stand physically separated by our primary database server (stand by server is completely separate to our existing main server) server.
  
  My questions are:
  
  1. don't we have to take advantage of a new license for custody of data?
  2. what other license should we acquire for the above settings?
  3. we would have a separate Installation of Oracle database on the standby server?
  4. If we have a named user license 150 on the primary database should purchase us a new license user named 150 for the confirmation Server?
  5. are there other things I have to consider in what concerns the granting of licenses for our project?

  OK, here's how my speailist license put, Data Guard as a product is free, but is not the database instance. A physical standby is a database, it must be so licensed, however the expert of the license indicates that licenses you buy for the execution of the physical standby can be ubtained at a substantially reduced rate as they would be called limited licenses. It's not data hold is the cost, it is the cost of an another database on another machine. According to you, current license, you can be covered however, you may not. Everything I say is call a specialist to license Oracle Metalink support, call the guy or gal who has sold you Oracle licenses or appeal and certified Oracle partner/reseller can help you with a specialist of the license and have a licensing discussion/examination before implementation. Oracle support is not those who understand the licenses and how this all works, he did this and like them, always thought that data guard and physical databases Eve were free and included and recently corrected, hard enough I might add.

• 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.

  Best regards

  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 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

  List copies of newspapers archived to database with db_unique_name ORAPRIM

  You sure you want to delete the items above (enter YES or NO)? NO.

  It is the removal of primary archives that have not yet been applied on the eve.

  Delete policy 'APPLIES ON STANDBY ALL' value on the primary:

  RMAN > show archivelog deletion policy;

  RMAN settings for database with db_unique_name ORAPRIM are:

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

  RMAN > delete archivelog until 'sysdate;

  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.
