  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 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.

• 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.

• Data Guard - allocation of licenses and other fundamental questions before setting it up.

  Hi all

  Please allow me to submit some questions about Oracle Data Guard.

  There are 2 databases 'authorized and ready ':

  -a single instance of the "alfa", Oracle Enterprise Edition 10.2 database,

  -"bravo", Oracle 10.2 Enterprise Edition, Real Application Clusters database

  I have to "align" congratulations to alfa on a daily basis, so that--in case of failure of the main 'alfa' site - recovery is possible change to the site "bravo."

  (1) even if we can afford a loss of data corresponding to the period little uttered at the end of the last daily alignment (no need to 'transactional' alignment between the two databases), I assume that the best approach to meet this need in terms of efficiency and manageability consists on two databases including in a Data Guard configuration.

  Am I wrong?

  (2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?

  (3) only the Data Guard configuration require

  (a) additional licenses?

  (b) additional material/software resources for host machines?

  (5) the release of two databases must be equal to the specific to the component version number (10.2.0.1, for example)? Or, for example, is a 10.2.0.1 able to work with a 10.2.0.3 db db in the Data Guard configuration?

  Thank you very much in advance!

  Hello

  (1) even if we can afford a loss of data corresponding to the period little uttered at the end of the last daily alignment (no need to 'transactional' alignment between the two databases), I assume that the best approach to meet this need in terms of efficiency and manageability consists on two databases including in a Data Guard configuration.

  Am I wrong?

  You have reason, physical hosting it good thing. For the most part, you will get impact with until or unless data loss because of some problems of network (or a configuration problem)

  (2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?

  Logical standby is a little different from the physical standby mode

  (3) only the Data Guard configuration require

  (a) additional licenses?

  (b) additional material/software resources for host machines?

  Data features come with Enterprise Edition - perhaps for the active database "cost of the additional license.

  (5) the release of two databases must be equal to the specific to the component version number (10.2.0.1, for example)? Or, for example, is a 10.2.0.1 able to work with a 10.2.0.3 db db in the Data Guard configuration?

  Good level to maintain the same level of oracle binaries / patches and still the support of heterogeneous DG
