• Difference between database mirroring and cloning?

  Hello
  
  Can someone tell me precisely the difference between the Mirrorring database and cloning?
  
  Is the database mirroring and multiplexing Similarly?
  
  
  Thank you
  Rajesh

  Rajesh, yes even if, as stressed, Oracle does not use the term of mirroring from the database.

  I did a search on the term: mirroring, using 11g manuals and got 329 hits and after scanning several pages of them all the entries appear to be associated with the mirroring of the files. In ASM you groups mirror and you strip mirror all (MCSS) and so on.

  The product of Oracle Data Guard is how Oracle 'mirrors' a database. As noted Oracle does not use the term, but I think that your use is compatible with the term as defined in the dictionary of COMPUTING.

  A related term danger which might be of interest is REPLICATION. Oracle has built-in features to replicate data from one object to another, potentially on a remote database.

• Use Oracle database with LabVIEW

  I am new to Oracle database usage and I worked on the MS Access database. I want to use the Oracle database in one of our applications to store data and retrieve data using SQL instead of MS Access instructions. Please give some suggestions which less than the version that I can use? y at - it a free version that I can get? What I need deilver with software.

  Yes, there is a free version called Oracle XE which works very well. In fact, it is intended (which Oracle referred to as) OEM applications. It is free to use, and there is assistance available forums which are also free. The free version has all the features of the business, with a couple of limit: first of all, it will only access a carrot in your CPU. Second, the maximum data size is 4 GB.

  In regards the connection to it, check out this discussion.

• Connect to the Oracle database fails when you use Microsoft ODBC or OLE DB Driver

  There was a problem when you apply the KB3126587 hotfix where connections to an Oracle database using the Microsoft ODBC driver fails if run from automated processes. Running the same process manually would succeed. The update issued KB3147071 solved the problem successfully.

  Yesterday, several patched have been applied and the problem came back. The patches are: KB2862152, KB2868626, KB3163244, KB3168965, KB3170455, KB3163251.

  I saw yet no acknowledgement or difficulty of Microsoft. I prefer not to uninstall security patches, but it is a problem of production.

  Any ideas what specific patch maybe breaking it again?

  Thank you

• Database alert is not triggered when the Oracle database monitor by mistake.

  Hello

  Database alert is not triggered when the monitor of the Oracle database by mistake. If we test the alert manually alert works correctly. Could someone let me know the solution for this.

  This isn't a question of PC or operating system. You should post your questions in the forums of Oracle database.

• Bug in "DBSS" - not available on a database mirror? Or a real failure?

  Does anyone else make false positives on 'DBSS' rule - not available for mirrored databases?

  Once every week or two I get a fatal alert "Not available" for the 'DBSS' rule - not available on all databases mirrored to my server.  It takes only a few minutes in Foglight, then goes back to a normal state.

  I looked at the newspaper database monitoring for the mirror and the principle, all SQL server and Agent logs, all the server event logs... nothing.  The history of all mirrored databases have no signs of availability according to the real itself SQL Server issues.

  The only reference to this rule Foglight is:

  https://support.quest.com/search/SolutionDetail.aspx?ID=SOL76183

  Go through the article, I looked at the data stored in the "DB" State for the affected databases, it says "Not available" for the times, that the alert has developed.  However, I can't find anywhere on the current SQL Server where this error can come.

  I have not particualrly want to go rushing to false positives fatal alert indicating that my mirror is not available

  Any thoughts on what I might try?  Everyone knows about this problem?

  Or is this just a blip?

  See you soon,.

• What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Hello

  It's confusing.

  This looks like a 2nd review SQL for Oracle 12 c.

  What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Can someone explain.

  Roger

  OK - I guess I should have held off a few hours before my previous answer.  I just got an email in the Certification of Oracle program manager. Now, I have inside information.

  1Z0-071 is a SQL new test and the role it plays is between that of the review of databases SQL and SQL Expert.  Specifically, unlike review of databases SQL, passing it will give proof of the OCA for people who spend. I don't know more than that yet.  The review details page is not available and if the subjects are currently a grey area for me.  I'll probably create a blog on the review, if I can get a few details about it.

• How to use references from web third party service with service Cloud Computing to Oracle database schema

  APEX 5.0

  Cloud Computing service for the Oracle database schema

  
  

  I'm in the middle of do a proof of concept.  Basically, I need an application with security of the stored data, UI, user, data loading, and able to post data via an external web service said.  It seems that with the database schema Oracle cloud service, it is not possible to use web service references that are not in the field.

  If I try to use a service via http reference, I get:

  ORA-20987: APEX - the requested URL was forbidden. Contact your administrator. -Contact your administrator of the application.

  If I try to use the same reference service via https, I get:

  ORA-29273: HTTP request failed

  ORA-06512: at & quot; SYS. UTL_HTTP & quot; line 1130

  ORA-29259: end-of-input reached

  I read somewhere that cloud services only https can be used.  Is this true?

  And then I read somewhere to use the protocol https, the portfolio must be configured to store certificates, etc.  However, I read somewhere else that the portfolio cannot be configured because there is no access to the instance database with the Oracle Cloud Computing database schema service.  Is this true?

  If both are true, how can I make a call to post data to an external web service?  Or do I need to use a different Cloud Computing service?  Or do I need my own instance of Oracle DB?

  Any help would be great.  Thank you!

  It turns out there was a problem with the remote rest service.  After successfully calling a rest service that was created using SQL Workshop, I tried different remote rest services and they all work.  Sorry for the confusion.  I thought it was very strange that the schema of database service wouldn't be able to do it easily.

• 10.2.0.5 Oracle database link (Linux - x 86) for MS SQL Server 2012 (x 64)

  Please guys, I really need your help on this issue.

  I tried using freetds driver but when I use db link I get this error:

  ORA-28500: connection between ORACLE and a non-Oracle system has sent this message:

  [Generic connectivity using ODBC] [S1000] [9013] error General nvITrans_BeginT - rc = - 1. Please see the log file for more details.

  ORA-02063: preceding 2 lines MIXERI

  To cite that I can connect to the remote sql server through isql tool with no problem at all. I study a lot and I found no solution for this error, so to this end, I will try to find another alternative way.

  
  

  Is there another way to manage the communication link between the system of 2 DB db?

  Thank you

  Hello

  S erro coming from the ODBC side then you can try the following-

  1. change the listener.ora LD_LIBRARY_PATH for-

  (ENVS=LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/db/oracle/10.2.0/lib)

  stop and start the listener.

  2. don't you get the error even if you delete the entry-

  HS_FDS_SQLLEN_INTERPRETATION = 32

  3. get a debugging bridge route-

  -Comment the entry
  HS_FDS_TRACE_FILE_NAME = /db/oracle/10.2.0/hs/admin/MIKSERI.trc

  then the tracks go to the location by default with default names-

  /DB/Oracle/10.2.0/HS/log

  -set the level of the trace-

  HS_FDS_TRACE_LEVEL = DEBUG

  -start a new session of SQLPLUS, run select, close the session.

  -Download the trace from somewhere, it can be displayed by our care.

  It can also be an idea to install and use the 11.2.0.5 last DG4ODBC gateway that is certified with RDBMS 10.2.0.5 and available at My Oracle Support you.

  Patch 13390677: 11.2.0.4.0 PATCH SET FOR ORACLE DATABASE SERVER

  which must be installed in a new and separate ORACLE_HOME.

• Turning to Oracle RAC to the only Oracle database

  Hi all

  We are responsible for "make a copy" of Oracle RAC database a customer and our plan is to finish with the FCAC and allows you to host a new unique Oracle database. Very few of us familiar with CARS and looking for suggestions on how to do it (without affecting the source JAR).

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  Comments/suggestions appreciated.

  Thanks in advance.

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  It is an option. Data pump does not care if the source and/or destination is CARS or a mix. If the database is too large, it can take a lot of time to complete.

  Another option is to use the DOUBLE of RMAN feature. And another option is to restore the database from a backup.

  See you soon,.

• AGAIN starts after only one physical disk has several partitions makes no sense to the production oracle database?

  Dear Experts,

  Don't + REDO1 diskgroup have only one physical disk has several partitions makes no sense to the production oracle database?

  For example

  • + Diskgroup Redo1 have 2 50 GB disks (fact these 2 discs are the same physical disk partitions OR these should be separate disk as recommended approach)?
  • + Diskgroup Redo1 have 2 drives of capacity 50 GB (for RAID 1 + 0)
  • + Diskgroup Redo2 have 2 50 GB disks
  • + Diskgroup Redo2 have 2 drives of capacity 50 GB (for RAID 1 + 0 )

  Thank you and best regards,

  IVW

  Hello

  Partitioning your disks for ASM configuration as 'A' might make sense. If you lose one disk, you have the discs to another.

  'B' totally make sense if you have lost the disc that you have lost all group ASM and you need to change this with something like 'C '.

  But obviously you need redundancy ASM configured appropriately.

  How to insert data into the new table?

  I am trying to find an INSERT SQL command like this:

  INSERT INTO met_p6_ref_pointb

  SELECT 'ID', location, type_prev, date_publi,

  row_to_json (met_p6_point): jsonb

  OF met_p6_ref

  Join met_p6_point using ('ID');

  But there is no row_to_json in oracle 12.1

  Suspicion and advice would be appreciated.

  Thanks adavance.

  I have the solution. This is the query.

  I think he can help other people who want to use JSON data:

  INSERT INTO met_p6_ref_pointb

  SELECT 'ID', type_prev, localization, date_publi, "{'ID':}" | ID | ","DATE_VALID":'''|| LTRIM (DATE_VALID) | " ', 'VALUE': ' | {VALUE |'} '

  OF met_p6_ref

  Join met_p6_point using ('ID');

  It works for me.
