• 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

  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

• 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.

  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.

  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.

  This is because as soon as you open the standby database, application of roll forward stops. At least that's true up to 10 gr 2, 11 g, you have the option "Active Dataguard" (requires an additional license), which allows to apply, while the database is open.

• Loads of parallel data through SQL connect and replace existing data

  I'm doing a load of multiple data through SQL Connect using the following statement.  Just try to put in place a .bat file to automate the process but not sure that whenever it executes this statement adds data to existing or replaces the data? I tried to write an override for this but it works for instructions which contain the import section.

  Import of database data App.DB connect as username identified by password

  with the help of several rules_file, rul1, rul2, rul3

  load_buffer_block starting with buffer_id 10 on error write to 'C:\\dataload.err ';

  We can add spec commit buffer such as "replace all data ', 'create group', 'Add' to this import statement? The default declaration overrides the value whenever the data is loaded?

  Thanks in advance!

  you have an option in the rules file "Overwrite out of values."

• 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.
