What is the difference between the type of table and view?

• JDeveloper with MEV / possible FGAC? i.e. the oracle portal tables and views

  I am trying to create some objects to view based on the tables and the views of portals oracle. However, I always get the following error message.
  
  ORA-06510: PL/SQL: not supported by the user-defined exception
  ORA-06512: at "PORTAL. WWCTX_SSO', line 1407
  ORA-06510: PL/SQL: not supported by the user-defined exception

  ORA-06512: at "PORTAL. WWCTX_SSO', line 1469
  ORA-06512: at "PORTAL. WWCTX_API', line 152
  
  It's because I did not put the context using plsql. That is to say
  
  Portal.wwctx_api_private.set_Context (p_user_name = > 'PORTAL', p_update_flat = > true);
  
  Is it possible to use the portals in jdevloper and defining the framework first. I think that the portal database uses vpd, fine-grained access control.

  Hello

  using ADF BC, you can override the session prepared on the AM method to set the context.

  public void prepareSession (_session Session)
  {
  super.prepareSession (_session);

  some PLSQL as
  String appContext = "Begin ctxhrpckg.set_userinfo ('" + getApplicationUserName () + "');" END; « ;
  java.sql.CallableStatement st = null;
  Try
  {
  St = getDBTransaction ().createCallableStatement(appContext,0);
  St.Execute ();
  } catch (s java.sql.SQLException)
  {
  throw new oracle.jbo.JboException (s);
  } Finally
  {
  Try
  {
  If (st! = null)
  {
  St.Close ();
  }
  } catch {} (java.sql.SQLException s2)
  }

• What is the difference between a version of MAR and the software win7 INKL?

  * Original title: MAR v INKL

  What is the difference between a version of MAR and the software win7 INKL?

  Hello

  Thanks for posting your query in Microsoft Community.

  • What exactly you're talking about when you say, 'Version INKL of Windows 7?

  I'll be happy to answer your query, however, please explain more about abbreviation INKL. There is a version called Office of ink that is used in the Tablet PC.

  Here's the other version of Windows, you can make reference to:

  MAR - Microsoft Authorized Reacondicionador

  A new PC requires a version of windows with a new key license installed if purchased from a manufacturer.

  A refurbished PC is allowed to use an existing product key (2nd hand if you like) as long as it is always delivered with a certificate of authenticity (COA). This is referred to as MAR (Microsoft authorized Reacondicionador) which means that Microsoft allows to use existing keys/licenses products.

  Buy a version of windows means MAR technically you buy a second hand copy - being however, software, so it comes with COST, will make absolutely no difference at all.

  N and KN editions

  The features in N and KN Editions are the same full versions of their equivalent, but do not include Windows Media Player or other technologies related to Windows Media, such as Windows Media Center and Windows DVD Maker because of the limits set by the European Union and South Korea, respectively. The cost of n and KN Editions are the same as the full versions, as the Media Feature Pack for Windows 7 N and Windows 7 KN can be downloaded for free from Microsoft.

  Generations of VL

  
  VL builds work with VLK (volume license key). Volume license keys can be used to activate multiple installations of the software without a mechanism (for example, a product activation mechanism) controls the total number of facilities. The license for the software is going to impose restrictions on the use of the key. In general, the license will limit the key to a certain number of facilities which must be only the Organization of the licensee and also to place the holder under the obligation to keep a record of the number of facilities, hold confidential and perhaps even require that the holder organization makes available for a software license check check that his use of the key is in the terms of the license.

  Please let us know what exactly are you referring to when you say version INKL of Windows 7, so we can further research and answer.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

• Can someone tell me what is the difference between a default playback device and a default communication device?

  original title: sound settings are very complex. Can someone tell me what is the difference between a default playback device and a default communication device?

  In fact, I use the recording software to record songs instead of downloading. Some recorders record their own drivers and they work fine. But sometimes, they do not respond. The DD Realtek Audio Manager is sick with something. People suffer a lot using this. My questions are endless. Some of them are:

  • What is "Realtek Digital Output?
  • Save devices-part of sound cards?
  • What are animals like 'Audio CD' and 'Stereo Mix' displayed on the DD Realtek Audio Manager?

  I'm sorry for not being specific, but I need a very good idea of how to deal with the settings of the sound in windows 7. And one thing, I have no microphone plugged but always Realtek HD Audio Manager detects? Why?

  Hi SandiKollol,

  A communication device can mean different things, but mostly it is used to allow voice communications on the internet.

  A playback device plays his return, such as your speakers or headphones.

  I hope this helps.

  Hello world! I'm new to "VMware vSphere API", and I have a question to ask you to help:

  What is the difference between "vShpere SDK ro Perl"and "vSphere Web Services SDK (for Java or c#)"?

  -What are the different programming language? Is there another difference?

  I'm looking forward to your reply.

  If you are new on the VMware API/SDK, highly recommend you take a look at the following: Getting Started with vSphere SDK - Update for SDK 4.1 release

  vSphere SDK for Perl is just one of the many client SDK for vSphere API that is flush with vcenter times and ESX (i) as a standard Web service.

• What is the difference between buying creative cloud membership and subscription purchase?

  What is the difference between buy creative cloud membership and purchase subscriptions (month to month/year)?

  If I'm not allowed to buy creative cloud in my country, can I still purchase subscription?

  Forward to your response.

  Thank you

  MM

  Those are two separate monthly subscriptions for individual applications allowing you to cancel at any time. It is the most expensive but the most flexible way of the subscription.

  Creative cloud is a collective term for a subscription to the Master Collection of apps all most all of the additional products and services that come with all members of the cloud. http://www.Adobe.com/UK/products/creativecloud/tools.html

  If you want only a soft then a stand-alone subscription is the way to go.

  If you want at least two applications, then an annual membership of cloud is cheaper overall.

  Which country are you? Cloud memberships are not available in all countries.

  It seems that the list type is not the same thing as the java.lang.List. What is the type of list on Earth? What type can I set the output of the java.lang.List result? Are there any useful document on the types between Java and process management? Description too little on the list in the manual (lcwb_95_help.pdf)

• ThinkPad E420 - what is the type of this laptop SATA interface? Is this 2 SATA or SATA 3?

  Dear all,

  What is the type of interface SATA of ThinkPad E420? Is this 3 SATA or SATA 2?

  I noticed that this laptop hard drive transfer rate is 3 Gb/s, which means that it is a SATA 2 HARD drive, isn't it? It also means that the laptop SATA interface is SATA 2?

  I tried searching the support site and product from lenovo for this information, but I can't.

  Thanks in advance.

  Best regards

  Haris

  You're right, the E420 is SATA2.

  SATA3 is very rare in the laptops!
