• Best practices for a NFS data store

  I need to create a data store on a NAS and connect to some servers ESXi 5.0 as a NFS datastore.

  It will be used to host virtual machines less used.

  What are the best practices to create and connect a datastore NFS or networking and storage view bridges in order to get the best possible performance and decrease is not the overall performance of the network?

  Concerning

  Marius

  Create a new subnet of layer 2 for your NFS data warehouses and set it up on his own vSwitch with two uplinks in an active configuration / eve of reunification. Uplink should be variously patches in two distinct physical switches and the subnet must have the disabled bridge so that NFS traffic is not routable in other parts of your network. NFS export can be restricted to the IP address of storage host IP (address of the VM kernel port you created for NFS in the first step), or any address on that subnet. This configuration isolates traffic NFS for performance, ensures the security and redundancy. You should also consult your whitepapers of storage vendors for any specific recommendation of the seller.

  Data warehouses can be made available for the guests you wish and you can use Iometer to compare PAHO are / s and flow rate to see if it meets your expectations and requirements.

• 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 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.

• 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.

• 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.

• 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.

  Best EqualLogic practices ESX

  en.Community.Dell.com/.../20434601.aspx

  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.

  Here is a link to VMware which addresses this issue and has links to other Dell documents which confirm also that it is fixed in 5.1.

• Best practices for network configuration of vSphere with two subnets?

  Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

  Install the most common iSCSI would be traffic between hosts and

  the storage is not being routed, because a router it could reduce performance.

  If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

  MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

  vMotion a deployment scenario might be something like:

  NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

  standby

  NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

  NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

  NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

  NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

  VMK (192.168.4.10) active

  You would place you on VLAN 10 storage with an IP address of something like target

  192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

  gateway configured in ESXi would be the router the VLAN 20 with an ip address of

  something like 192.168.2.1. I hope that scenario help set some options.

• Best practices for SQL

  I started a discussion a few weeks there is movement .vmdks from the supplier of storage to another in regard to and got some great answers.  What I didn't ask was if the hard contain databases SQL is there special considerations when you cut storage EMC VNX (pools versus grpoups raid) or when the data store is created in vCenter.  I know that this may be more an EMC forum question but maybe someone in the world of VMware has a recommendation or can provide a link to best practices for the VNX.  Thank you.

• 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?

• best practices for the storage of the vm and vhd

• 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!

  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.
