Best practices for hardware issues

Hi all.

I suspect my questions are unanswered, but here go us...

Assuming that is the CPU of the same frequency and generation, which is better: less physical Sockets with more physical cores/socket OR more physical sockets with less physical cores/socket?  (For example, a "populated with dual-core CPU Server Socket 8" or '2 socket populated with processors octo hearts'?-of course,. )

In the same vein, which would be better: a cluster with 10 guests with simple plugs or 5 guests with double?  (Same CPU and with the understanding that there is no VM requires more resources that the host can provide.)  No claim of CPU or RAM)

Thoughts?

Thank you.

Hello

In my view, licenses vSphere is always per-socket, an important point for those who write checks!  And then there's NUMA.  If you have an idea of the size of the virtual machines, you are going to be running, you can purchase the equipment that matches your NUMA characteristics.

As for your second question, you ask the old question of the ladder up against the scale.  You will find many opinions as people you ask.  The answer, "it depends," is largely true here if you need to enumerate and analyze your needs and your constraints.  A few things to ponder scale vs. scale out:

-With hosts more, smaller, less virtual machines will be affected during a failure of the host

-On the other side of the first, fewer and larger armies with multiple virtual machines can take more time to recover these VMs for an HA event

-More great guests costs usually more little guests

-Small hosts limit the size of your virtual machines compared to larger armies

It has more advantages and disadvantages of each as well as what has already been mentioned in this thread.  Good luck!

  • Best-practice for hardware virtualization?

    Hardware virtualization is disabled by default when I create new virtual machines in my VMware clusters. But what are the best practices for this what settings are recommended? Are there reasons NOT to activate the hardware virtualization?

    IMO there is no advantage in allowing virtualization of hardware if you have no need for the virtual machine (for example, a virtual host of the ESXi).

  • ApplicationStorageDirectory - best practices for the issue of games

    So, I worked on a game that uses air. My problem is that I've been storing my game resources in the application directory. That would be fine except that the game has a built-in editor that requires the ability to write files. Adobe has locked since ApplicationDirectory for write access, so now I don't know where I'm supposed to store all my game files editable user - which is potentially active ALL game.

    The seemingly obvious choice is to use ApplicationStorageDirectory. While this is not ideal, because it seems that I would need to duplicate all the assets from the inside of the application in the repository at the start, it would provide a standard and easy to find a place to store modifiable game resources.

    However, this article (on this site) clearly tells me that I shouldn't do that. It is a good point. Backup of all game assets is messy proposal. And while I can see users who take advantage of capabilities editting as enjoying the backup, for the average player, that would be a pretty big trouble.

    What am I, so I expected to do in this scenario? I need an accessible place in writing, where the user and the application can easily access all game resources (XML, Image, MP3). I don't want to choose an arbitrary location, and I'm disabled by the application needing home redundantly data just to be copied into the destination directory since there is no way for me to delete it once it is copied since I can't write in the application.

    Thanks for the thoughts.

    Hello

    A couple of things come to mind. Is actually not Adobe that locks the application under Windows directory, it's one thing to MS permissions with folders under Program Files.  But whatever it is, it's always a problem.

    As you said, you can copy files to first launch but depending on the size, this could be annoying after a user just sitting through the installation.  It is also not very friendly when you want to uninstall.  You might want to consider sub launches the installation program with the AIR of a separate setup program that also takes care of installation of game resources to another accessible location in writing.  Maybe it's customizable by the user, but at least she is monitored by the installer that should allow you to uninstall properly.

    Is it not possible to conserve resources with your application, but the editor of the architect such as only content created by the user would be in a writable directory of the user (for example a subdirectory out of their documents folder?)

  • Best practices for vsphere 5.1

    where can I find the doc more up-to-date about berries EQL configuration / best practices with vmware vsphere 5.1

    Hello

    Here is a link to a PDF file that covers best practices for ESXi and EQL.

    This doc mentions specifically that the storage Heartbeat VMKernel port is no longer necessary with ESXi v5.1.  VMware has corrected the problem that made it necessary.

    If you add it to a 5.1 system it will not hurt.  It will take an IP address for each node.

    If you upgrade 5.0 to 5.1, you can delete it later.

  • 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,.

  • Best practices for tags

    Hello

    In the bundled applications Tags are used in most applications. For example. in App Customer Tracker, we can add tags to a customer where these tags are stored in a varchr2 column in the Customers Table.
    In my case, I've pre-defined tags real estate (Real Estate) in a table of research called TAGS. For example, Full floor, furnished, equipped, duplexes, attached... What is the best practice for tag properties:
    1 - to store these tags in a varchar column in the table of PROPERTIES using the Shuttle box.
    OR
    2. to store in a third table Eg, PROPERTIES_TAGS (ID PK, FK property-ID, TAG_ID FK), then use the LISTAGG function to show tags in one line in the report properties.
    OR
    You have a better option?

    Kind regards

    In my case, I've pre-defined tags real estate (Real Estate) in a table of research called TAGS. For example, Full floor, furnished, equipped, duplexes, attached...

    These seem to be two different use cases. In the bundled applications tags allow end users to join free-form metadata to the data for their own needs (they are sometimes called "folk taxonomies"). Users can use tags for different purposes or different tags for the same purpose. For example, I could add 'Wednesday', 'Thursday' or 'Friday' tags customers because these are the days that they receive their deliveries. For the same purpose, you could mark the same customers '1', '8' and '15' by the numbers of road trucks making deliveries. You can use 'Monday' to indicate that the client is closed on Mondays...

    In your application you assign to the known properties of predefined attributes. It is a model of standard attribute 1:M. their view using the metaphor of the label is not equivalent to the user of free-form tags.

    What is the best practice for tag properties:
    1 - to store these tags in a varchar column in the table of PROPERTIES using the Shuttle box.

    If you do this, how can you:

  • Search for furnished duplex properties effectively?
  • Change in the world "mounted" to "integrated"?
  • Ratio of the number of properties, broken down by full floor, double-sided, equipped...

    OR
    2. to store in a third table Eg, PROPERTIES_TAGS (ID PK, FK property-ID, TAG_ID FK), then use the LISTAGG function to show tags in one line in the report properties.

    As Why use Look up Table, shows the correct way to proceed. It allows the data to be indexed for efficient extraction, and issues such as those above should be dealt with simply by using joins and grouping.

    You might want to examine the possibility of eliminating the PK ID and use an index table organized for this.

    OR
    You have a better option?

    I'd also look carefully your data model. Make sure that you're not flirting with the anti-pattern VAE. Some/all of these values are not simply the attributes on the property?

  • AF best practices for video

    I'm using an EOS 7 d for 1080 p HD video shooting. New to SLR camera and digital video. I have watched several tutorials but do not yet have a good understanding of what the best practices for the development.

    If I put the camera in AI Servo it will auto focus if the subject is moving away or toward me with depress me back AF-ON or the shutter button? Or should I press one of these buttons to make the camera continues to focus?

    You know tutorials or video lessons that cross using update with the video?

    Thanks in advance!

    I don't know any tutorials, but more serious videographers say it is best to use only the manual focus.

    Trial and error is a good teacher, when it comes to video DSLR. You'll quickly learn that video Auto Focus is really bad with the 7 d and most of the people do not use it all together.

    The method that works for me is to use AF before the filming of the video and then adjust manually if you want to you to shoot the video. With the help of f/8 or f/11 to keep everything in short without having to keep the setting.

    More recent Canon DSLR's like the T4i, T5i, 70 d and SL1 have a "hybrid AF" that does a much better job of AF during video, but it is not yet as good as a camcorder

  • Just improved m tips on best practices for sharing files on a Server 2008 std.

    The field contains about 15 machines with two domain controllers, one's data is the app files / print etc...  I just upgraded from 2003 to 2008 and want to get advice on best practices for the establishment of a group of file sharing. Basically I want each user to have their their own records, but also a staff; folder. Since I am usually accustomed to using windows Explorer, I would like to know if these actions can be done in the best conditions. Also I noticed on 2008 there is a feature of contacts. How can it be used? I would like to message or send an email to users their file locations. Also, I want to implement an admin at a lower level to handle the actions without making them far in on the server, not sure.

    I read a certain bbut I don't like test direct more because it can cause problems. So basically a way short and neat to manage shares using the MMC, as well as the way that I approach their mail from the server of their actions. Maybe what kind of access cintrol or permissions are suitable also for documents. Also how can I have them use office templates without changing the format of the model.

  • [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.

  • Best practices for color use in Adobe CC?

    Hi all

    Is there an article that describes the best practices for use of color in Adobe CC?

    I produce a mixture of viewing online (PDF, for the most part) and real world print projects - often with the obligation for both. I recently updated my PANTONE + bridge books for the first time in ages and I am suddenly confused by the use of Lab colors in the Adobe Suite (Illustrator and InDesign).

    Everything I found online, looks like Lab color mode preferred to use because it is device independent. And perceptual (on screen), it looks much closer to the color, it is trying to represent. But when I mark a Spot color Illustrator rectangle using laboratory coordinates, to the sides of a rectangle using PANTONE + bridge CP and then export it to PDF, the version of CP to mix CMYK color corresponds exactly to my Pantone book - while the version of laboratory (after converted to CMYK using the ink Manager) is far away.

    I have this fantasy to manage only a single Illustrator or InDesign file for both worlds (PDF) printed and online. Is not possible in practice?

    Any info describing the basic definitions of the color modes - or even a book tracing more than use them in the real world - would be much appreciated!

    Thank you

    Bob

    Here are a few best practices you can already do.

    1 make sure that your color settings are synchronized on all applications.

    2. use a CMYK profile appropriate for your print output. Lab spot colors convert to CMYK values based on the CMYK icc profile.

    3. include icc profiles when save or export pdf files

    In theory, your imagination is possible today. It requires color management and the use of icc profiles. You can place RGB images in InDesign and use Pantone colors in your objects. The problem lies in the printers. If a printer uses a RIP with built in Pantone library, the colors will match when printing. Unfortunately, this kind of CUT is more expensive and not enough printers use them. Most of them is always manually approximate CMYK values composition given Pantone colors.

  • Best practices for managing exceptions and success messages.

    Hey people,

    These days I've been shooting packages to clean my application. And question came to my mind, ' should I treat my exceptions the right way?


    So I want to ask you met guys, what is the best practice for this? (I want to learn it until it's too late )

    Currently I have a function that returns "OK" if all goes well.


    return('OK');  

    Can I manage my exceptions like this

      EXCEPTION
        WHEN OTHERS THEN
          ROLLBACK;
          RETURN (SQLERRM);
    
    

    At THE SUMMIT, I have a process that calls the function and then checks if the function returned "OK".

         IF cRet not LIKE 'OK%' THEN
          RAISE_APPLICATION_ERROR(-20000,cRet);
         END IF;
    
    

    And in 'process Error Message' I put "#SQLERRM_TEXT #" so that I can see what error occurred.

    Question aside, how do you manage your messages of success?

    Currently in 'process success Message' put something along the lines "Action completed successfully". What to do about all the processes.

    Do you want to do differently?

    I really want to hear what you have to say since I'm tired of feeling like this is a terrible way to manage these things.

    Hi Para,

    Para wrote:

    I don't know of situations where my service throw exceptions like no_data_found.

    and I need to know that the process is not so I can get to see my # #SQLERRM_TEXT.

    I got this by increasing the error in the application (which I think is a bad way to go) if the return is anything other than 'OK '. I get my application error in the process of the apex, and not in my service.
    And I want to show the inline error in the notification. (Which I am currently with my approach).

    You can use APEX_ERROR. ADD_ERROR in your PL/SQL process to throw exceptions in Oracle APEX.

    Hi gurus,

    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.

    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.
