• The FRA diskgroup separate for each prod database?

  Hello

  Env: Oracle 11 g 2 EE (11.2.0.3), 6.2 RHEL 64 bit

  Storage: file system

  Databses: ten databases on the PROD and 20 on the DEV

  I have two existing servers with above configuration - a DEV and a single PROD. I have to move all of the databases from two servers to new servers.

  I have two options. Configure the servers again exactly the same way (same software oracle, same mounts-points, directory structures, etc.) and move/copy the databases above. The other option is to use ASM for storage instead of file system.

  Customer asks a diskgroup FRA separate for each DBA database. His reason is that if the FRA gets filled by archivelogs because of some process in the databases, all databases stops responding.

  • It's a legitimate concern and what is the best way to deal with this kind of situation?
  • Should I create a diskgroup FRA separate for each database?

  The archivelogs are backed up every 20 minutes for each PROD database.

  Please advise!

  Best regards

  You can limit FRA for each database with the parameter DB_RECOVERY_FILE_DEST_SIZE.

• What to do for the main database when a physical database ensures converts a standby time of the snapshot

  Hello

  Need of the primary database to implement the flashback database when a physical database ensures converts a standby time of the snapshot? Or something to do with the primary database? I find some documents this work to allow the return of flame for the primary databases, but I think that he didn't need to do.

  Thank you

  Best regards.

  I did recently, I have not configured flashback on primary, only configured in the standby mode. I converted the standby database and restored the changes after the test. Primary database continued to send archives to the standby site. Instant once converted into sleep mode, as mseberg mentioned overlaps with the sync state after starting MRP.

• How can suggest us a new DBA ECO certification for very large databases?

  How can suggest us a new DBA ECO certification for very large databases?

  This web site, or what phone number can call us to suggest the creation of a certification of VLDB ECO.

  The most important databases that I've ever worked with barely more than 1 trillion bytes.

  Some people told me that the results to be a DBA change completely when you have a VERY BIG DATABASE.

  I could guess that maybe some of the following topics in the configuration can be on it,

  * Partitioning

  * parallel

  * more large block size - MAS vs. OLTP

  * etc.

  Where I could send a recommendation?

  Thank you Roger

  This forum is probably your best choice, Brandye would be one of the contacts I would use to make such a request.  If you are really interested in this, I would be further demand more.  Specifically, most Oracle certifications available to have a corresponding course available in the OU. If you want to create a new certification, one of the most compelling arguments would be to suggest a certification that tests information for which there are already one or more courses.  Looking at the current offerings of courses 12 c, the following two seem to come more close to what you ask for:

  Database Oracle 12 c: implement partitioning Ed 1

  Parallel processing in Oracle Database 12 c Ed 1

  These areas are covered somewhat in 1Z0 - 117.  You will need to make a case for a certification that hit different areas of knowledge.  Looking at the course for both subjects, partitioning has more that are not covered in-depth on 117.  However, it is supposed to be a 12 c Data Warehousing expertise certification coming out this year that may require a partitioning good knowledge.

• Data modeling for a small database tutorial - understand the part 'Creating relationships between entities'

  I'm trying to understand and make use of Tutorial: modeling of data for a small database

  In this tutorial, I'm supposed to make Entity Transactions containing two attributes that designates the bosses (patron_id) and Books (book_id) (2.1.4) entities

  Later, I add two one-to-many relationships that attributes mentioned twice in the entity of Transactions (patron_id1 and book_id1). (2.1.5)

  So here are my questions: what is the purpose of creating attributed to point 2.1.4 if they are then reproduced in paragraph 2.1.5?

  If she could be crucial, I use Oracle SQL Developer Data Modeler Version 4.0.0.825 Build 825 on jdk1.7.0_25.

  Bonus question: how to turn attributes types on the logical diagram? I can't find the option anywhere...

  I would be really grateful for each answer and all the stuff!

  Looking at the documentation for version 2.  I checked 3.3 and 4.0 EA3 and corrected tutorial you can download the latest version and use this documentation.

• You are looking for a compatible database XML system

  Hi all
  
  I'm looking for an RDBMS (Relational Database Management System) that manages the XML data in a relational way.
  I found the IBM DB 2 XML Extender. However, I don't know if this system is already in use (because the last release was in 2003).
  I would be very grateful if you could help me find what I'm looking for.
  
  PS. for RDBMS, XML data processing, we find two categories: systems that support XML (they store XML data using a special type of data as a BLOB, CLOB,...), or the native XML systems (data XML stor in its hierarchical structure, so the fundamental unit of storage is XML document). So, I am looking for a system that supports XML and NOT a native XML system.
  
  Thanks in advance.
  
  Best regards

  I misunderstood your found thing

  If I understand correctly say you

  Database compatible XML - store XML data using a special like BLOB, CLOB data type
  database XML Native - XML data in the hierarchical structure stor

  projection of oracle xml db, you can store your xml file in xmltype in clob or BLOB or as a file in the operating system
  looks so much like oracle xml db is compatible XML native XML databases :)

  I'm going crazy ;)

• upgrade from 3.2 to 4.1 - error handling for the unavailable database links

  Hello
  
  I have a 3.2-> upgrade problem 4.1 associated with error handling for the damaged database links.
  
  I have a conditional button Exists on a page that contains a SQL query to related tables. However, for 10 minutes every day where the target of the link database becomes a cold backup, the query fails. In the apex 3.2 old, I just had an error within the region where the button is located but otherwise, the page was still visible:
  
  "Is not valid/not exists condition: ORA-02068: following a serious error of MYDBLINK ORA-01034: ORACLE not available ORA-27101: there is no shared memory realm."
  
  However, in the apex 4.1.0.00.32 I get the following unhandled error and click 'OK' brings me to the edit page when logged in as a developer.
  
  that is, the page cannot run at all so that the links to the database fail to this one area.
  
  Treatment of error condition.

  I did a search and read the http://www.inside-oracle-apex.com/apex-4-1-error-handling-improvements-part-1/ page, but the new apex error handling is not clear to me, and I don't know if the apex_error_handling_example provided on this page would be applicable to this situation.

  Hello

  It was my fault, I forgot that the code will be compiled on the fly which already fails if the table/view of deletion is not accessible. Nice that you found yourself workaround.

• A SCN for the entire database and the different SNA for the data files?

  DB Version: 11 g
  
  I always thought that there is a unique SCN for the database as a whole.
  A quote from the link below as
  When a control point is completed, Oracle stores the RCS individually in the control for each data file file
  http://www.dbapool.com/articles/1029200701.html
  
  
  What does that mean? There is a SNA for the entire database, and there are individual SCN for each data files?

  Well, unfortunately, the article says more bad than good things. Or if I can't call them wrong, they are rather confusing and rather than clear things for the reader, its making them appear to look more confused.

  First things, YVERT is used for read consistency (CR) mechanism and the backbone of the notion of Multiversioning. The control point is the mechanism to help that recovery is decided. Contrary to what said article, not any kind of checkpoints update both the data file and the control file, and also, there is not a type of them as well. In addition, the article says that the LAST_CHECKPOOINT is set to NULL, while its actually set to the infinity since it is not possible to detect the moment when the database is opened, that the last issue of control over the file would be. In the case of complete control point, this number is saved and is also associated with the toa Controlfile own database leader at the next startup. If this is not the case, there is an inconsistency in the stop_checkpoint of the data file and the stop_checkpoint reocrded in the control file, leading to a recovery of the instance.

  There are several types of control points. Similarly, there are several types of SNA as well. Without going into the details of these, IMO, the article simply means that when the control point write over a file passes, oracle updates the file checkpoint on it and this is recorded in the Controlifle. as well.

• A query takes twice as long for an identical database on two separate systems.

  Hi, I'm looking for help with a performance issue on a particular database.
  
  I'm running the query
  ' for $o in the collection ("rx.dbxml") / RX [dbxml:metadata("janusId") = "12345"] descending return $o/@dos < id item = '{replace (dbxml:metadata("dbxml:name",_$o)' & #34; (», «_»)} "> {$o} < / item > '"
  on two different systems through a ServerProxy xmlrpclib python object. This is the my test request, but the other query performance presents the same problem.
  
  Data on both systems are identical, and the time required to execute this query is the same for both systems throughout
  each database, except one. For this particular database, the time required to run the query on system B is double
  the system has.
  
  This is only the case for a particular database that makes me think it's a matter of data?
  However, the data are identical on both systems.
  
  Is anyone aware of all data related issues that could trigger such a success of performance-based
  the configurations below? What should be my next step to diagnose this problem?

  Try looking at the exit of db_stat for each system to the query itself.
  1 clear stats:
  db_stat z m
  2. run the query
  3. look at his stats:
  db_stat m

  Note the suspicious differences. You can / must also monitor the disk and the e/s during queries. If the plans are really the same and the data are the same that points to differences in system that would essentially be IO. At least this is the first place to look.

  Kind regards
