• Are from all points of view dynamic performance actually views of $ V_?

  DB version: 10G
  
  All dynamic performance views actually start with V_$? The views V$ (without the underline in the meantime) regularly access we are in fact synonymous to views V_$. Right?

  The views V$ are actually public synonyms for corresponding SYS. Views V_$.

  To list all views of $ V on your system:
  SELECT name from V$ FIXED_TABLE whose name like ' V$ % ';

• Impossible to views of dynamic performance of queries in my views

  I want to create my own opinion that returns information about the database engine, as follows:
  
  create or replace view AfDbEngine as select 'ORACLE' as EngineType, version as EngineVersion of v$ instance
  
  However, I get the following error message:
  
  SQL error: ORA-01031: insufficient privileges
  01031 00000 - "insufficient privileges".
  * Cause: An attempt was made to change the user name or password
  without the privilege appropriate. This error also occurs if
  trying to install a database without the need for employment
  access privileges.
  When Trusted Oracle is configure in DBMS MAC, this error may occur
  If the user has been granted the privilege necessary for a higher label
  that the connection is active.
  * Action: Ask the database to perform the operation or grant administrator
  the required privileges.
  For users Trusted Oracle get this error, well that granted the
  the privilege that is suitable for the top label, ask the database
  administrator to grant the privilege to the appropriate label.
  
  Am I really missing some privilege (which one?), or is he basically not allowed to question the views of $ v in my point of view? I have all the privileges necessary to assess the following:
  
  Select 'ORACLE' as EngineType, version as EngineVersion of v$ instance
  create or replace view AfDbEngine as select 'ORACLE' as EngineType ' 11.1.0.6.0"as the double EngineVersion
  
  but obviously I prefer not hardcode the version number in my definition of the view.
  
  Thank you

• Performance views

  Hi guys,.
  
  I have a vision that is made for four different points of view.
  Now the problem is its taking a long time to run as the sub views have a lot of conditions and joins.
  What are the Options I have except Mview of the same to increase the performance of the main display.
  
  
  -Manish

  Hi Manish,

  normally, the optimizer tries to merge views, and if nothing prevents this to happen (such as the use of virtual analysis of function or rownum etc.), then a query against the view will be equivalent it terms of running queries on the underlying objects.
  In any case, we see the plan to give an opinion on the tuning.

  You can see whether or not your advice work by observing the changes in the plan.

• Content VS App Deployment Performance Viewer

  I am having some problems with DPS for Android. The biggest problem with Android is HTML overlays. I understand from reading several messages that HTML is unreliable or just does not on Android devices. (I currently design for a Samsung Note 10.1.)

  When I access an HTML page that exists on a server from a link in the application that uses the built-in browser content viewers, the results are not consistent.

  For example, I have a soft, I'm actually binds to a type of work on my server. Sometimes, the page will be load and display the form, but it will soon disappear. Once I receive the form is displayed again, touch the textfields and trying to enter information do not work. It's as if it's a static image.

  If I test the same functionality on an iPad, it works very well, like what it is I'm doing.

  My question: is this isolated to Adobe Content Viewer or the content viewer reflect the performance of the Android app should be exported and deployed as an app for the Google Play store?

  Also, can you link out of the application and use the unit for the related items web browser?

  The biggest problem is HTML.

  Thanks for any help.

  Of course, there is the superposition of hypertext link where you can choose to open the link in the browser in the app or the device browser. Remember in browser application is not a full flight Navigator as the browser on the device. If the performance and reliability of the two different

• Materialized with a dynamic column view.

  Hello
  
  Is it possible to use the materialized in function view.
  A column in the view is dynamic, which means that we are entering a parameter in the view.
  
  Thank you

  A way to "set view" in Oracle is to use "sys_context '.

  http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/functions184.htm#SQLRF06117

  You set the context and then you set your display that uses the sys_context parameter.

• Creating dynamic materialized views: insufficient Privileges?

  Hi all
  
  I am currently doing a procedure that will recreate materialized views as columns are deleted or added to a table by the selection of the user to the application level. I wrote the procedure, and it displays the correct syntax to create a materialized view. However once I pass this dynamic sql statement to be executed immediately, it fails, saying: I don't have sufficient privileges. I have sysdba grants on this user in my dev environment. What Miss me? Has it something to do with immediate execution and the privileges associated with the use that? Any help would be greatly appreciated!
  
  
  Kind regards
  TimS

  Within a stored (by default) procedure DEFINER rights, only the privileges that are granted directly to the user, not those granted through a role as SYSDBA, are available.

  -If you change the stored procedure to use the rights of the applicant, the privileges granted through a role are visible. However, this requires that the appellant, not the owner of the procedure has the permissions to create the materialized view.
  -If you grant the CREATE MATERIALIZED VIEW privilege (and all other privileges your code requires) directly to the user, which would also solve the problem.

  Hello

  Since I did the update to indesign 3 days ago

  my files are automatically in the upper display.

  I'm trying to change, but as soon as I restart the mac or software, it returns systematically.

  So, some of my files are almost impossible to open.

  Do you have a solution?

• Dynamic performance of plsql block of relaxation.

  Dear oracle Experts.
  I'm using the following oracle database.
  
  Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
  PL/SQL Release 10.2.0.4.0 - Production
  CORE 10.2.0.4.0 Production
  AMT for Linux: release 10.2.0.4.0 - Production
  NLSRTL Version 10.2.0.4.0 - Production
  
  I have a problem in the execution of the trigger. I have a small plsql block in the trigger, and I want to run it as a dynamic medium. but it gives the error. Please find the code of the trigger. Here my intension is that the column name used in trigger must be dynamic. In the future, if I want to pass the name of the column, I do without modification in the trigger.
  The error im getting is "ORA-01008: not all variables.
  
  Or y at - it another way to achieve this goal. Please suggest your ideas. Thank you!!!

  "THEN."
  INSERT INTO hema_clob VALUES (: NEW.'|) V_COL_NAME |') ;
  END IF;
  END;';
  IMMEDIATELY RUN PL_SQL_BLOCK;
  END;

  As immediate execution will execute the code as if it were a separate process of the trigger, this dynamic PL/SQL block is unlikely to have access to the: NEW and: OLD trigger variables.

  Dynamic SQL is pretty bad.

  Read the doc:

  Once an instance is started, the views V$ read from memory are accessible. Views that reads data from disk require that the database mounted, and some require that the database be open.

• Views by giving details of the undo segments?

  Hi all
  
  Please, are there view (s), questioned on this matter, elaborate us on the contents of the tablespace, undo (in particular on all lines that are stored in the undo segments)?
  
  Thank you.

  Hello

  Dynamic performance views are useful to get space on the undo tablespace information
  V$ UNDOSTAT
  Contains statistics for monitoring and tuning undo space. Use this view to help estimate the amount of undo space required for the current workload. The database also uses this information to help address cancel its use in the system. This view is significant only in the management of automatic cancellation mode.

  V$ ROLLSTAT
  For automatic cancellation mode of administration, information reflect the behavior of the undo segments in the undo tablespace

  V$ TRANSACTION
  Contains the rollback segment information

  DBA_UNDO_EXTENTS
  Displays the status and the size of each measure in the undo tablespace.

  WRH$ _UNDOSTAT
  Includes instant statistics in V$ UNDOSTAT information. Please refer to the Oracle database DBA 2 day for more information.

  WRH$ _ROLLSTAT
  Includes instant statistics in V$ ROLLSTAT information. Please refer to the Oracle database DBA 2 day for more information.
