Differences between process and procedures

• Difference between function and procedure

  Hi all
  
  My doubt is that the procedure can be used to return multiple values with OUT parameter and function can also be used to do the same if necessary to return multiple values with OUT parameter.
  
  So with this point of view, which is maybe the difference between these types of the two objects. and obviously if necessary to choose one of these two, we'll go to procedure, why not function?
  
  What is perhaps the reason for this?
  
  Thanks in advance.
  
  Kind regards

  Would you care to show what you mean. To the best of my knowledge this last statement is not correct.

  The main difference for procedures and functions it program design.

  A procedure should be used for something that is running a process, where nothing is required to be returned.
  A function should be used when a value is required to be returned.

  Yes, the procedures can have OUT parameters (as can functions) but that is generally considered bad practice. If you have values be returned, you must use a function with an appropriate return type (structured type if necessary) so that all the requirements of data is returned via the return value. IMO the only acceptable practice to use variables is when you use a variable IN OUT for something in a procedure for this element which is manipulated by the procedure, so for example you'd 'ManipulateData (myData); as a procedure rather than "myData: = ManipulateData (myData);" in function, where the latter would be using resources of additional memory (copies of data) in most cases.

• What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

  I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

  AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

  Mesh

  • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.
  
  
  • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient
  
  
  • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.
  
  
  • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

  Ports

  • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.
  
  
  • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

  Problem solvers

  • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.
  
  
  • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.
  
  
  • Several AXIEM processes are multithreaded as EMSight.

  Speaker

  • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

  I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

• Differences between navigationClick and the TrackWheelListener

  In fact, I have a few questions here.

  What are the differences between navigationClick and the TrackWheelListener?  When should I use that one.  I'm trying to follow the MVC pattern.

  Is there a good example of a code that follows the MVC pattern?

  The TrackwheelListener really must be used when a peripheral wheel and make your own custom management of movements on the device wheel.  Due to the transition between the wheel (eg. 8700) and trackball devices (eg. 8100 and more) we mapped the trackball to the TrackwheelListener events in an attempt to ensure backward compatibility.  However, it does appear the following limitations:

  (1) left and right movement does not exist in a TrackwheelListener, but it is possible using the Trackball.  As a result, users have a user experience on a Trackball device.  Many vendors allow the user, hold down the ALT key and roll the ball up and down control to indicate the left/right movement as a work-around.  But again, this isn't the best user experience.

  (2) TrackwheelListener is an independent mechanism of the UI classes.  Therefore, once you receive notification of a movement or click you are then required to determine which field in your user interface should work on this movement or click.  This requires additional processing and the code to determine how to handle the event.

  Therefore, the recommendation is that you would substitute navigationClick, navigationMovement, and navigationUnclick methods to manage all movement of the trackball and scroll wheel.  It will manage both wheel and trackball devices correctly which solves #1.  It is also integrated in the UI classes themselves which reduces the impact of the #2 above.

  The only drawback to the use of these methods is that it requires your application built with the JDE 4.2.0 and requires a minimum of 4.2.0 terminal software.  For the vast majority of third-party developers, v4.2.0 is a sufficient minimum requirement given the proportion of the market that is running 4.2.0 or higher (over 75%).

• Difference between FYI and Notification

  Hi all

  Sorry for the dummy question, but I'm a newbie BPM/BPMN and try to understand better what I use for my modeling process.

  Could you please explain to me the difference between the FYI and Notification? When it is better to use?

  Asked me to send an e-mail notification to users just to let them know where the process is, no manual action is required and the process must continue without interruption.

  Thanks for any help.

  Fairlie

  Hi Fairlie,

  Here is a tool of 2 page that lists all the different activities in BPMN, gateways and Oracle 11g and 12 c BPM events and what they serve each to- https://blogs.oracle.com/soacommunity/entry/bpm_poster_for_bpm_suite

  In your use case where you want to send an email to someone, and no manual intervention is required, use the Notification activity.

  News is an Interactive activity and causes a work item instance appear in the Inbox an end user in the workspace.  The difference between this and other types of interactive activities is that the work item instance does not stop at this activity in the process, but instead continues on the next activity in the process.

  A Notification activity is an automatic activity which does not create an instance of work item in an Inbox in the workspace, but rather sends a message of electronic mail, instant messaging, SMS or voice.

  When the work item instances reach these two activities, they do not stop and continue them automatically the next activity in the process.

• Difference between ADFFacesContext and FacesContext object?

  Hello
  Whatz the difference between ADFFacesContext and FacesContext object?

  Stratum FRO mthe docs:

  ADFFacesContext:
  A context object that exists largely as a mirror for the Apache Trinidad RequestContext, but also provides APIs specific to ADF Faces.

  RequestContext Apache Trinidad:
  The context class information by request and by webapp required by Trinidad. A RequestContext object can be retrieved with the method static getCurrentInstance(). There is a single and same RequestContext object active in any thread.
  This class does not extend FacesContext; This is intentional, which stretches from FacesContext requires support for the FacesContextFactory.

  FacesContext:
  FacesContext contains all status information by related request processing of a single application of JavaServer Faces and rendering of the corresponding response. He went to and potentially modified by, each phase of the lifecycle processing request.
  A FacesContext instance is associated with a specific request at the beginning of the treatment, by a call to the method getFacesContext() of the FacesContextFactory instance associated with the web application current demand. The instance remains active until its release() method is called, after which no further reference to this instance is allowed. When a FacesContext instance is active, it must not be referenced from any thread other than the one on which the servlet container that is running this web application uses to process this request.

  I don't know exactly what you're asking. The query

  UPDATE WH_T_ITEMS A
     SET BALANCE_QTY =MAX(ITEM_QTY)
   WHERE STORE_ID = V_STORE_ID
     AND ITEM_SERIAL = V_ITEM_SERIAL   ;
  

  is not valid SQL from Oracle. As MAX aggregate functions cannot be used in a query like that because Oracle has no idea what you aggregate by. There is nothing preventing Oracle to change the syntax of the SQL language to allow an aggregate be used this way, but there is usually no reason to extend the SQL language like that.

  You can assign the result of a query that included a total of BALANCE_QTY column, i.e.

  UPDATE WH_T_ITEMS A
     SET BALANCE_QTY = (SELECT MAX(ITEM_QTY) FROM <> WHERE <>)
   WHERE STORE_ID = V_STORE_ID
     AND ITEM_SERIAL = V_ITEM_SERIAL   ;
  

  I think I mentioned in some of your previous discussions, a data model where you have a table of ELEMENTS that has an ITEM_QTY and the BALANCE_QTY looks suspicious. You assign the value of the ITEM_QTY column to the BALANCE_QTY on the same line does only increase anxiety.

• What is the real difference between the following procedures?

  What is the real difference between the following procedures in the DBMS_STATS package:
  GATHER_SYSTEM_STATS
  GATHER_DICTIONARY_STATS

  GATHER_SYSTEM_STATS: System statistics to describe the characteristics of the system hardware, such as i/o and CPU performance and utilization of the query optimizer. When choosing an execution plan, the optimizer evaluates necessary IO and CPU resources for each request. Statistics system helps the query optimizer estimate the costs of IO and CPU, allowing the query optimizer to choose a best execution more accurately plan.
  GATHER_DICTIONARY_STATS: Collect statistics for all items in the dictionary.

• Difference between Nohup and &

  Hello
  
  Please help me understand the difference between nohup and & UNIX... I will be really grateful if you owe me explaun in detail...
  
  Thank you
  Martine

  "nohup" is to allow a process run disconnected. Thus, the process can run even if your disconnection.

  '&' is to allow a process running in the background. This allows you to run another command/program of the same shell you have invoked the first process of.

  If you use '&' alone, when you log out, the process that you started in the background would also stop because it is not disconnected from your shell, it is still a "child" of your shell process.

  So, if you want to start a program and also make it continue running even when your disconnect / close your shell, you would use the 'nohup' and the '&' as

  nohup run_my_program &
  

  NOTE that the behavior of the "nohup" varies from shells - sh, ksh, bsh, csh then you must read the documentation on the special shell you use and/or test the behavior of nohup first on your particular connection.

• Difference between 'Reload' and "Reload (Override Cache)"?

  Https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_navigation, what is the difference between 'Reload' and "Reload (Override Cache)"? What makes "ignore cache"?

  Reloading Web pages and cache bypass aims to obtain a new copy of perhaps obsolete or damaged files currently stored in the disk cache.
  You can do it like the first attempt if a normal charging does not seem to provide a version of a Web site or if you are having problems with a Web site otherwise.

  We usually have advice that if you have questions:

  Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

  • Hold down the SHIFT key and click the Reload button
  • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
  • Press 'Command + shift + R' (Mac)

  Clear the cache and delete cookies only from Web sites that cause problems.
  "Clear the Cache":

  • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

  'Delete Cookies' sites causing problems:

  • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

  Start Firefox in Safe Mode to check if an extension or theme (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problems.
