• What are the best practices for creating only time data types, and not the Date

  Hi gurus,

  We use 12 c DB and we have a requirement to create the column with datatype of time only, if someone please describe what are the best practices for the creation of this.

  I would strongly appreciate ideas and suggestions.

  Kind regards
  Ranjan

  Hello

  How do you intend to use the time?

  If you are going to combine with DATEs or timestamps from a other source, then an INTERVAL DAY TO SECOND or NUMBER may be better.

  Will you need to perform arithmetic operations on time, for example, increase the time to 20%, or take an average?   If so, the NUMBER would be preferable.

  You are just going to display it?  In this case, DAY INTERVAL in SECONDS, DATE or VARCHAR2 would work.

  As Blushadow said, it depends.

• Best practices for the reader to 'Data' between VM?

  Hello

  So on my box ESXI, I have a 250 GB drive. I was wondering what the best practice is to have a 'data' drive shared between VM? I'm pretty new to virtualization so would like to view

  I would basically following drive configuration...

  Win 2008 R2 - 60 gb

  Win 2008 R2 - 60 gb

  Ubuntu 10.10 - 20 GB

  (Shared between the two areas of 2008) DATA - 100 GB

  Thank you.

  The only way to do this is to assign the drive to a virtual machine and create a network share. Unless you use a file system that supports concurrent access to files, an attempt to present the disk to several systems would probably end by the corruption of data.

• Best practices for Smartview when upgrading from Excel 2003 to Excel 2007?

  Anyone know the best practice for Smartview during the upgrade from Excel 2003 to Excel 2007?
  
  
  Current users have Microsoft Excel 2003 with Smartview 9.3.1.2.1.003.
  
  Computers are upgraded to Microsoft Excel 2007.
  
  
  What is the best practice for Smartview in this situation?
  
  1. do nothing with Smartview and just install Excel 2007.
  
  2. install Excel 2007 and then uninstall and reinstall Smartview
  
  3 uninstall Smartview, Excel 2007 installation and then install Smartview
  
  4 something else?
  
  
  Thank you!

  We went with option 1 and it worked very well. Be aware that OAS Treaty substantially slower in Excel 2007 to 2003. Many users have been/is unhappy about the switch. We have not tested SV v11 yet, so I don't know if it has improved performance with Excel 2007 or not (hopefully it does).

• Best practices for p2v - when to stop the physical machine?

  After you perform a p2v conversion, when should I stop the physical machine? By default, the virtual machine is turned off after the conversion and characterized by a DHCP address and not the static address that was on the physical machine... Why is this? Not the virtual machine is a duplicate... maybe it's a setting I'm missing the conversion.

  Looking for a better practice for the p2v conversion process.

  Using Virtual Center 2.5 and the converter built-in.

  Thank you, Rick

  Hello and welcome to the forums.

  I tend to do the conversion and to choose to not to turn on the virtual machine later.  Once the conversion is completed, I make changes on the hardware as needed and then make sure that "Connect at Power On" is not checked in the device status of the NICs.  Now you can power up to the virtual machine and do what you need to do to prepare (uninstall the old software, change HALs, etc.) without fear of being on the network with the same name or IP address.  Once everything is good in Event Viewer, Device Manager, etc. - I shut down the physical server and then turn on the virtual machine with a "wired" network adapter to test.

  Another option would be to use the "Customize the identity of the virtual machine" option towards the end of the wizard import, if you need to be able to have the physical server and the virtual machine on the network at the same time.  This customization will give you virtual machine, a new name server and SID, and then you could just set it to a different IP address.

  Good luck!

• Best practices for the handling of data for a large number of indicators

  I'm looking for suggestions or recommendations for how to better manage a user interface with a 'large' number of indicators. By big I mean enough to make schema-block big enough and ugly after that the processing of data for each indicator is added. Data must be 'unpacked' and then decoded, for example, Boolean, binary bit shifting fields, etc. The indicators are updated once / sec. I'm leanding towards a method that worked well for me before, that is, binding network shared variable for each indicator, then using several sub-vis to treat the particular piece of data, and write in the appropriate variables.

  I was curious what others have done in similar circumstances.

  Bill

  I highly recommend that you avoid references.  They are useful if you need to update the properties of an indicator (color, police visibility, etc.) or when you need to decide which indicator update when running, but are not a good general solution to write values of indicators.  Do the processing in a Subvi, but aggregate data in an output of cluster and then ungroup for display.  It is more efficient (writing references is slow) - and while that won't matter for a 1 Hz refresh rate, it is not always a good practice.  It takes about the same amount of space of block diagram to build an array of references as it does to ungroup data, so you're not saving space.  I know that I have the very categorical air about it; earlier in my career, I took over the maintenance of an application that makes excessive use of references, and it makes it very difficult to follow came data and how it got there.  (By the way, this application also maintained both a pile of references and a cluster of data, the idea being that you would update the front panel indicator through reference any time you changed the associated value in the data set, unfortunately often someone complete either one or another, leading to unexpected behavior.)

• Best practices for the storage of data the program Config on Vista?

  Hello world

  I'm looking to get recommendations about what where (and how) to better store the configuration data of the program for a LV executable runs under Vista.  I need to store a number of things like the location of the window, the values of the controls, etc.  Under XP I stored straight in the screw own execution path.  But in Vista, certain directories (for example, C:\Program Files) are now restricted without administrator rights, so if my program runs from there, I don't think it's going to be able to write its configuration file.

  Also at the moment I'm just using scripture to the block of spreadsheet to store my variables.  Is it his good or are they better suggestions?

  Thank you!

  For the configuration data, I use the setting screw or screw Configuration OpenG. The formula proved to be flexible during development (adding new values is backward compatible).

  XML would be nice, but the current implementation is unflexible when you add / change the data structure (the old configuration file cannot be reused).

  If the amount of data is small (just a post windows and size or some of the file path), the windows registry is an alternative (giving a game unique for each user, if you wish).

  I have no experience with Vista.

• Best practices for the integration of the Master Data Management (MDM)

  I work on the integration of MDM with Eloqua and are looking for the best approach to sync data lead/Contact changes of Eloqua in our internal MDM Hub (output only). Ideally, we would like that integration practically in real time but my findings to date suggest that there is no option. Any integration will result in a kind of calendar.

  Here are the options that we had:

  1. "Exotic" CRM integration: using internal events to capture and queue in the queue changes internal (QIP) and allows access to the queue from outside Eloqua SOAP/REST API
  2. Data export: set up a Data Export that is "expected" to run on request and exteernally annex survey via the API SOAP/REST/in bulk
  3. API in bulk: changes in voting that has happened since the previous survey through the API in bulk from Eloqua outside (not sure how this is different from the previous option)

  Two other options which may not work at all and who are potentially antimodel:

  • Cloud connector: create a campaign questioning changes to schedule and configure a connector of cloud (if possible at all) to notify MDM endpoint to query contact/lead "record" of Eloqua.
  • "Native" integration CRM (crazy): fake of a native CRM endpoint (for example, Salesforce) and use internal events and external calls to Eloqua push data into our MDM

  Issues related to the:

  1. What is the best practice for this integration?
  2. Give us an option that would give us the close integration in real-time (technically asynchronous but always / event-based reminder)? (something like the outgoing in Salesforce e-mail)
  3. What limits should consider these options? (for example API daily call, size response SOAP/REST)

  If you can, I would try to talk to Informatica...

  To imitate the integrations of native type, you use the QIP and control what activities it validated by internal events as you would with a native integration.

  You will also use the cloud api connector to allow you to set up an integration CRM (or MDM) program.

  You have fields of identification is added objects contact and account in Eloqua for their respective IDs in the MDM system and keep track of the last update of MDM with a date field.

  A task scheduled outside of Eloqua would go to a certain interval and extract the QAP changes send to MDM and pull the contacts waiting to be sent in place of the cloud connector.

  It isn't really much of anything as outgoing unfortunately use Messaging.  You can send form data shall immediately submit data to Server (it would be a bit like from collections of rule of integration running of the steps in processing of forms).

  See you soon,.

• [ADF, JDev12.1.3] Best practices for maintaining a form validation

  Hallo,

  in my application, I need to create a registration form which contains fields that must be validated (for example they should follow a format like e-mail, phone number, tax code,...).

  If the data inserted by the user are ok, a new record in my custom db table Users will be created.

  I would like to know which are the best practices for maintaining the validation, which means the place where the controls must be made and a message to the user who fills out the form when something goes wrong.

  The best vo or EO or managed bean? Or some controls should be put in the OS, others in the VO and other in the managed bean?

  I would be happy if you could give me some examples.

  Thank you

  Federico

  Assuming you want the validation on the value of the field to any screen data can be entered in (and possibly web services that rely on the same BC ADF) then put the validation on the definition of the attribute in the EO.

  If you want to add a little more friendliness and eliminate some of the network traffic to the server, you can also implement the validation client in your page - for example by using the regular expression validator.

• What are the best practices for a new employee to learn inside the instance of their business of Eloqua as efficiently as possible?

  We have companies everything changed at some point in our lives. And we all go through the process in the first weeks, where you feel new and are just trying to figure out how not to get lost on your way in the mornings.

  On top of that, trying to familiarize yourself with your new company Eloqua instance can be a daunting task, especially if it's a large organization.

  What are the best practices for new employees to learn as efficiently and effectively as possible?

  I am in this situation right now. Moved to a much larger organization. It is a huge task trying to understand all the ins and outs not only society, but also of the eloqua instance, especially when she is complex with many points of integration. I find that most of the learning happens when I really go do the work. I spent a ton of time going through the programs, documentation, integrations, etc., but after awhile, it's all just words on a page and not absorbed.

  The biggest thing that I recommend is to learn how and why things are made the way they are currently, ask lots of questions, don't assume not that things work the same as they did with your previous employer.

  Download some base in place level benchmarks to demonstrate additional improvement.

  Make a list of tasks in the long term. As a new pair of eyes, make a list of things you'd like to improve.

• Best practices for SQL

• best practices for placing the master image

  Im doing some performances / analysis of load tests for the view and im curious about some best practices for the implementation of the image master VM. the question is asked specifically regarding disk i/o and throughput.

  My understanding is that each linked clone still reads master image. So if that is correct, then it seems that you would like the main image to reside in a data store that is located on the same table as the rest of the warehouses of data than the House related clones (and not some lower performing table). The reason why I ask this question, it is that my performance tests is based on some future SSD products. Obviously, the amount of available space on the SSD is limited, but provides immense quantities of e/s (100 k + and higher). But I want to assure you that if, by putting the master image on a data store that is not on the SSD, I am therefore invalidate the IO performance I want high-end SSD.

  This leads to another question, if all the linked clones read from the master image, which is general practices for the number of clones related to deploy by main image before you start to have problems of IO contention against this single master image?

  Thank you!

  Omar Torres, VCP

  This isn't really neccissary. Linked clones are not directly related to the image of the mother. When a desktop pool is created and used one or more data stores Parent is copied in each data store, called a replica. From there, each linked clone is attached to the replica of the parent in its local data store. It is a replica of unmanged and offers the best performance because there is a copy in every store of data including linked gradient.

• Best practices for deferred loading collection once but ensuring there?

  I'm confused on best practices for managing the "setup" of the form, where I need a remote call to occur once only once for the form, but I also need to make use of this collection for a combobox that will change when different lines in the DataGrid or clicked. Easier if I just explain...

  1. You click on a row in a datagrid control to modify an object (for this example we will say it is an "employee")
  2. The form you go must have a collection of objects 'Department' charged by a remote call. This collection of departments should only occur once, since it is not common for them to change. The departments collection is used to fill a combobox in form.
  3. You need to understand what Department of the comboBox control is the property selectedIndex by iterating over the departments and find one that fits the employee.department.id

  Individually, I know how I can do all of the above, but because of the asynchronous nature of Flex, I'm having hard time setting up things. Here are a few questions...

  My first thought was just put the loading of the departments in an init() method on the employeeForm who would load as an event on the form creationComplete(). On the component page grid when the event handler by clicking a line of fire, I then calls the setup() method on my employeeForm which stands at which selectedIndex to set to the combobox control looking at the departments.

  The problem is the resultHandler for the load of the departments could not returned (so departments could not be there when "setUp" is called), but I can't put my business logic to determine the correct combobox in the departmentResultHandler because it would mean that I would always have whenever I don't want the fire of the call to the remote server object.

  I have to miss a single best practice? Suggestions welcome.

  Hi there rickcr

  It is pretty rough and you need to make a few storage upward, but take a look below.

  
  http://www.Adobe.com/2006/mxml"layout ="absolute">
     
          Import mx.controls.Alert;
  Import mx.collections.ArrayCollection;
             
  private var comboData:ArrayCollection;
             
  private void Setup (): void {}
  If {(comboData)
  Alert.Show ("data are present")
  populateForm()
  } else {}
  Alert.Show ("data not '")
  getData();
  }
  }
             
  private void getData (): void {}
  comboData = new ArrayCollection();
  The result of this call, the installer again
  }
             
  private function populateForm (): void {}
  fill out your form
  }
  ]]>
     
     
     
         
         
         
         
     
  

  I think this example type of watch you want.  When you first click on tab 2 there is no data.  When you click on tab 2 once again, there is. The data for your combo will be stored in comboData.  When the component gets created first the comboData is not instansiated, just romance.  This allows you to say

  If (comboData)

  This means that if the variable contains your data, you can fill out the form.  Initially it is not so now the else condition, you can call your data and return the result of your data then you can say

  comboData = new ArrayCollection(), put the data in it and remember the installation again.  This time comboData is populayed and is so it will run the method populate the form and you can decide which selected item to affect.

  If it is on a large scale you want to look into the creation of a suitable handler class to handle this, but this simple demo shows you can test to see if the data is different.

  Hope it helps and gives you some ideas.

• Best practices for the application of sharpness in your workflow

  Recently I tried to get a better understanding of some of the best practices for sharpening in a workflow. I guess that I didn't know, but there are several places to sharpen. Who are the best? They are additive?

  My typical workflow involves capture an image with a professional DSLR in RAW or JPEG or import into Lightroom and export to a JPEG file for the screen or printing of two lab and local. 

  There are three places in this workflow to add sharpening. In the DSLR manually into Lightroom and when exporting a JPEG file or print directly from Lightroom

  It is my understanding that sharpening is added to RAW images even if you add sharpening in your DSLR. However sharpening will be added to the JPEG from the camera. 

  Back to my question, it is preferable to manually the sharpness in the SLR in Lightroom or wait until you export or output of your printer or final JPEG file. And additive effects? If I add sharpening to the three places I am probably more sharpening?

  You have to treat them differently both formats. Data BULLIES never have any sharpening applied by the camera, only JPEG files. Sharpening is often considered to be a workflow where there are three steps (see here for a seminal paper on this idea).

  I. a step sharpening of capture which compensates for the loss of sharp in detail due to the Bayer matrix and the filter anti-repliement and sometimes the lens or diffraction.

  II. A creative sharpening step where some details in the image are 'highlighted' sharpness (do you eyelashes on a model's face), and

  III. output sharpening, where you fix the loss of sharpness due to the scale/resampling for the properties of the average output (as blur because of an impression how process works or blurry because of the way that a screen LCD sets out its pixels).

  These three are implemented in Lightroom. I. and II. are essential, and basically must always be performed. II. until your creative minds. I. is the sharpening that see you in the Panel to develop. You need zoom at 1:1 and optimize the settings. The default settings are OK but quite conservative. Usually you can increase the value of the mask a little so that you're not sharpen noise and play with the other three sliders. Jeff Schewe gives an overview of a strategy simple to find the optimal settings here. It is for the cab, but the principle remains the same. Most of the photos will benefit from optimization a bit. Don't go overboard, but just OK for smoothness to 1:1.

  Stage II as I have said, is not essential, but it can be done using the local adjustment brush, or you can go to Photoshop for this. Stage III, however, is very essential. This is done in the export, the print panel Panel or the web. You can't really get a glimpse of these things (especially the sharpening printing-oriented) and it will take a little experimentation to see what you like.

  For jpeg, sharpening is done already in the camera. You could add a small extra capture sharpening in some cases, or simply lowering the sharpening in camera and then have more control in the post, but generally, it is best to leave it alone. Stage II and III, however, are still necessary.
