• major differences of exadata database, listener, process than the normal RAC environment?

  I would ask for any input about the major differences of exadata database, listener, process than the normal RAC environment.

  I know now the exadata have not only SCAN listeners, but many other listeners. expert here can provide clarification?

  Thank you

  All the right questions... Welcome to the world of Exadata.

  These are questions that could get into a lot more detail and discussion than a forum post. At a high level, you certainly don't want delete all indexes on Exadata. However, you need to index and an indexing strategy will change on Exadata. After you move a database from one not Exadata Exadata environment you are probably more indexed. Indexes used for OLTP transactions real - looking one or a few lines among others will usually quickly with an index. The index used to avoid a percentage of records but always returning number of records can often be moved. On the index depends on the nature of the workload and your application. If you have a control on the index, then test your queries and DML with the index (s) invisible. Check your implementation plan, the columns io_cell_offload in v$ sql, smart scan wait events to ensure you get intelligent analysis... and see if the smart scan is faster than using the index (s). The real-time SQL Monitor is an excellent tool to help with this - use dbms_sqltune or grid/cloud control.

  Parallelism is a great tool to help still speed up queries and direct path loading operations and can help prompt smart scans... but use of parallelism really depends on your workload and must be controlled using DBRM and the parallel init parms, possibly using same parallel declaration put on hold, so it is not overwhelm your system and cause concurrency problems.

  If you have a mixed environment of workload or consolidates databases on Exadata so my opinion is IORM plans should certainly be implemented.

• Character set US7ASCII AL32UTF8 migration to Oracle Applications database

  What is the best method to get the character set migration of Oracle Applications database?

  The options available are

  (1) export and import

  (2) CSALTER

  (3) DMU

  Database - 11g

  Applications - R12

  Please suggest some tips and recommendations.

  Kind regards

  Nordine salvation,

  I suggest you to refer the link: "How do I convert the character set for Oracle R12.1.1 running on 11.0.6 database Oracle US7ASCII' as it is very relevant to you."

  Response to your previous post would be:

  S ' stick to a plan

  -Try all of the activity on the TEST server for yourself

  -Troubleshoot and debug all the question from A - Z

  -On the successful implementation, make a backup of the Production and move the solution to PROD.

  If possible, run a lot of questions while doing the character set migration oracle applications, database because it contains the application tables.

  I accept the fact that EBS database is complicated to a database independent, but still all the features and debugging tools and troubleshooting is the same, although it is autonomous or EBS database.

  We should do if we stuck to the top in with and truncate in the application according to the CSSCAN results tables,.

  little tables when we checked in Metalink he says to avoid these tables which do not affect the database or application.

  Try in a Test Server, the above link helps you on the issue. You can find answer to some tables with loss in metalink if it's a bug, just lift a SRt solve your problem.

  What we must do if we are in important application tables, export and import will help in this issue.

  No, if we have available data with loss, then we cannot use the Import/Export and we will have to use CSALTER instead.

  is this the right method or must contact oracle support for assistance on important application tables.

  YES, I personally recommend you try and paralleling have ongoing Oracle support. So that you will have a guide from A to Z, in the case you're wrong

  Hope this helps

• How to find the version of Exadata database machine (whether X 2 or X 3 etc?)

  People,
  
  Y at - it a command that can tell us the Exadata Database machine to show it is V2, X 2 or X 3?
  
  The imageinfo command does not show this information.
  
  Appreciate any help on this.
  
  Kind regards
  Sameer

  Hi Sameer,

  This topic has been discussed on this forum last month, with some good ideas:

  Exadata version

  Also note that the V2 and X 2 have gone through several rounds of material during their life, so not all machine V2 have the same CPU features, for example.

  See you soon!

• B2B - BAM integration does not work with the Oracle XE database

  Hello
  
  Can someone explain the reasons in detail, 'the B2B - BAM integration does not work with the database Oracle XE'?
  
  Can't we use XE POC simple to demonstrate BAM?
  
  Published by: 975946 on December 27, 2012 04:14

  Hi Nithin,

  The main reason for this Oracle XE database can't handle such a huge process. Same Oracle XE is not supported in production.
  Note that SOA requires 300 process and BAM more than 100 processes (400 total), which is in addition to any other requirement its 500 to parameter.but process during the installation of Oracle SOA RCU, I hope you gave 300 single right.so his can't handle as much load if use B2B BAM integration.

  The ultimate goal is to have need to display active data in the right BAM reports? so, if you are using Oracle XE DB its may be not possible to show the active data.that the reason Oracle recommended use / works with Oracle 10 g Oracle 11 g versions EE and EE.

  Best regards

  Proably best to raise a http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP rather than having the old email address harvested by bots on the www.

  ... It is possible to find the strange question that is "questionable"... probably on 7 times out of 8 on careful reading of the review is probably just... on 10% of the time of the canididate was right. Prometric test old used to have a get out clause of Condé the "best" answer.

• My Oracle 8 database starts?

  Hi experts. Would like to be one.
  
  We have this old, old Oracle 8i database on a Windows Server. The name of the comic is PROD
  
  I need to connect to it, but I'm having difficulties.
  
  I'm looking for services-
  
  OracleServicePROD IS launched
  
  OracleStartPROD will not start (maybe because the database is already started?)
  
  OracleNamesService does not start
  
  AMT involves IS started
  
  
  Can anyone give me any advice for the verification of this database is started, please?
  Thank you, John

  Above described whereas environment and "" SVRMGR30. "» EXE", it is clearly not"8i"8.0.x,, right.

  I guess that I in "Oracle 8i database" in the first post is a typo.

• What are the risks involved in the Migration of Oracle 7 database to oracle10G

  Hello
  As a requirement of business me are necessary for the migration of our current production (Oracle 7.3.4) database to Oracle 10 G R2.
  
  I need to understand the risk involved in the affirmative and corrective action necessary.
  Your small contribution is greatly appreciated.
  
  Thanks in advance.
  
  Kind regards
  Vijay

  I did the migration of Oracle 8.1.6 to 10g database. Although I wasn't about many questions, questions I have met have been documented in Metalink. First, you will need to do a test migration, a UAT and then go to know the risk to go into production.
  I think you need to upgrade to 8.1.7 and migrate then import/export 10g directly. I had faced problems with the database with the Oracle Application database queues.

  Kind regards

• Saving UTL_FILE of Oracle 9i DataBase

  Hi all!
  
  I have a problen save an XML file that is generated in the SQL sentence in my Oracle 9i Database when the file is greater than 32 KB.
  
  To save the file that I use UTL_FILE library and I found that there is the problem.
  
  The code I use is as follows:
  
  CREATE OR REPLACE PROCEDURE SIGADMIN. PRUEBA_CAUC0004_EXT AUTHID CURRENT_USER IS
  CLOB XML;
  VXML varchar2 (100);
  ..
  ..
  xfile utl_file.file_type;
  doc xmldom. DOMDocument;
  ..
  ..
  BEGIN
  ..
  ..
  
  -Inicializamos el CLOB
  DBMS_LOB. CreateTemporary (xml, TRUE);
  ..
  ..
  
  -Pasar el DOM document a CLOB
  xmldom.writeToClob (doc, xml);
  
  xfile: = utl_file.fopen('TEMP_DIR','PRUEBA_CAUC0004.xml','w');
  ..
  ..
  WHILE (pos, len) LOOP
  VXML: = dbms_lob.substr(xml,100,pos);
  UTL_FILE.put (xfile, VXML);
  
  POS: = pos + 100;
  END OF LOOP
  -Liberamos los recursos
  xmldom.freeDocument (doc);
  UTL_FILE.fclose (x);
  ..
  ..

  In general, it is much easier to use"dbms_xslprocessor.clob2file" as shown in the following pseudocode:

  declare
     xml xmltype;
     cl   clob;
  begin
     xml := build_your_xml();
     cl := convert_xml_to_clob(xml);
     dbms_xslprocessor.clob2file (cl, 'YOUR_DIRECTORY', 'YOUR_FILENAME');
  end;
