• Measurement on the side time server? Best practices for the turn-based game

  Hello

  What would be the best practice for measuring time in a turn based game?

  I was looking at the timeout of the room, but to use that it would mean that, for each round, I put users in a new room?

  Is there a way where I can measure time serverside and keep users in the same room?

  If so, I could use php, otherwise, we would need java that allows to measure a time race.

  See you soon,.

  G

  Hello

  You can definitely use PHP or Java - we provide integration of server

  libraries for either. I don't know exactly what is the use case, so I can't

  comment on what makes the most sense, but if it is not information which must be

  totally secure, grading on the client can be a viable approach also.

• Merge on 64-bit Macbook Pro material offer real-time similar access to Hyper-V?

  I am a .NET software engineer, and I love Mac.

  In the PC world, there is a role in Windows Server 2008, called Hypter-V, which allows machines to virtualization (VMWare and virtual server products Microsoft) to access the hardware (CPU, RAM, etc.) in native mode, running at a speed in real time.

  Merger offer that a Macbook Pro to 64 - bit? If not, is it current?

  TIA

  In general, CPL3 code will operate at speed, as long as no defects are engaged.  This is true whether you use VT - x or binary translation.  There are exceptions to this, such as the CPUID instruction, which is required for VT - x intercept.  The CPUID instruction will run at native speed under direct execution with binary translation, but it will run significantly more slowly on VT - x.

  Performs a system call, however, works in native VT - x, but much slower speed in the direct execution with binary translation.

  Of course, any operation involving virtualized devices rather than the much slower than native physical peripheral tracks, given that the devices should be virtualized.

• charge battery for the first time and the best practices for maintaining the life of the new PC laptop battery

  Received my first laptop as a gift today (Pavilion touchsmart 15-n287cl).  You need to know 1.  How long to charge it for the first time or first several times; 2 do you need to unload and reload between each use completely and how long should it take to charge an average before being used again.  3. Since no instructions is a good idea to leave it plugged when you use all the time or the battery should be removed to improve the conservation of life?

  Thank you in advance, it has taken a lot of time to migrate from the desktop.  Want it to be a positive experience.

  Hello

  Modern batteries and chargers are now smarter than you.

  1. you can plugin and immediately to use the machine, the machine will stop charge when the battery is fully charged.

  2. No, we don't need to unload completely between uses, then as above. The recommendation is sometimes we run machine on battery until that up to 10%.

  3. when using AC is a way to protect the unit during the failure of current, all of a sudden, leaving battery on laptop.

• Controller time real-time FieldPoint or Ethernet interface

  Good afternoon

  The first feature listed on the PS-2000 product page is:

• Stand-alone embedded real-time controller or on PC distributed i/o Ethernet interface.

Everyone was able incorporate a PS-2000 as an Ethernet on PC distributed i/o interface?  In other words, have the PS-2000 as a FP-1600 Act?

There are some discussions forum discussions that dance around the subject, but I found no really one who responds to her.

Thank you

Ed

Hi edlad,

After playing with a FP-2010 for a while, I think you need to install LabVIEW Real-time on the controller to make it work, even though you are technically not to use it because you are not running a VI/executable on the controller. Regarding your problem with the installation of LabVIEW 8.5.1 on a PS-2000, it is disturbing because it should not be a problem that at all. In fact, I have personally been able to install LabVIEW 8.5.1 on many FP of the 2000s. For that matter, I suggest reformatting of the PS-2000 of MAX and try again.

ThinkG: Regarding your question on the use of a PSC-2220 to connect with belvedere, I don't know because the support of Lookout is managed by our subsidiary in Shanghai by e-mail only. However, I don't know that you can use this second ethernet port to connect with another network (cFP-180 x) FieldPoint module using the FieldPoint drivers. Here are some good articles about this configuration knowledge base. I hope they are useful.

• 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.

• Trend ServerProtect Real Time Scan kills Performance

  I've just virtualized a Windows 2003/Citrix Presentation Server 4.5 server on a host of vSphere with a NetApp FAS2020 using NAS as the data store where the virtual machine is stored.  There is no other guests of the VM on the host for the moment and the NetApp is not still used for other purposes (i.e. nothing should be taxing the material).  I found that ServerProtect V5.58 time real scan running on the Citrix server limits the CPU at a constant 100% once about 8 users are connected.  If I disable the real-time scanning, everything goes back to normal.

  Clearly, I must be able to protect users from malicious software Citrix sessions.  What is the best way to achieve this with Citrix/Terminal Server VMware?

  Someone at - it a version more recent ServerProtect or even OfficeScan running successfully within Citrix/Terminal Services hosted on VMware?

  Thank you

  D.

  Hello

  Moved to the Security Forum.

  Reinstall the trend after a P2V could help but maybe not.

  Trend also made programs specifically for virtualization and vSphere that will do A / V of the analyses using the API that will not also drastically affect performance vStorage, it's something to look into. Maybe but not 'real time' will allow better overall analysis.

• LabView is in real-time for Compact FieldPoint necessary?

  Hello!

  LabView is in real-time for Compact FieldPoint (CFP) necessary?

  (in German: Ist für die von Compact FieldPoint LabView time use real necessary?)

  Thank you.

  Bye, Ouafa

  Hello

  If you just want to use Labview for logging and graphics (via Ethernet) AND that you do NOT use a CFP-real-time controller, you don't need to LabVIEW Real-time.

  For example if you use OR cFP-1804-Ethernet/Serial Interface for Compact FieldPoint.

  (http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527)

  If you are using a controller real time you WILL LabVIEW Real-time.

  You can't function without it!

• using NI USB 9201 with LabVIEW Real-time

  Hello

  I try to use a USB of NI 9201 on a remote real-time target. Here's what I did: 1) tricked out of a desktop PC to serve as target RT using the instructions provided on the Web site of NOR. He now starts in an RTOS with LabView RTOS 9.0. (2) I communicated successfully with the help of a host computer that has a windows with LabView 2009 BONE and I installed the software from the computer remote RT target host using ethernet. However, my problem is when I plug NI 9201 USB on the target RT that I do not see the material listed on the devices tab in MAX and interfaces on remote systems. I tried to get the manuals for the HW 9201, but it seems not much explained here, or maybe I'm looking in the wrong places. Any help is greatly appreciated.

  PS: I am attaching 2 JPEGs for additional explanations (tab network settings and the settings of the system).

  Thanks in advance,

  Benoit.

  AVS,

  9201 USB is not supported on RTPCs please visit this link. Currently no usb-DAQ devices do not support an environment CRPC. Only the PCI DAQ devices are supported.

• a pc with a stand-alone module, real-time can display of its own data

  Hi all

  It is sort of a basic question, and it's probably why I can't find the answer explicitly in textbooks or the forum posts.

  If I want to use a PC as a unit in real time, and I install the LabView time real OS on it and make an Application of real-time on another machine and compile it in the PC target in time real LabView, can I attach a monitor or a kind of screen directly to the PC unit in real time to display some data I need?  Or do I still need a Labview PC to act as a host for display data and interface with a user?

  Thanks for the info!  I have some experience of labview, making some other applications but I have never used the RealTime module yet so I don't know much. So if there is a good place for more information in time real LabView for use a PC as a device target, which may also be of interest and would be appreciated!

  Thanks again.

  Hi Steve,.

  Our objectives in real time are designed to work in headlessly, which means that they are independent and have no user interfaces.  It comes to screens.  For a display of information, you must use a host VI, on a host computer. There are several ways to move data between a target RT and a host PC including, but without limitation, TCP, UDP, network flow, published static Variables of network and Web Services.  These are all covered in documents on best practices.

  Here is a page real-time best practices:

  http://zone.NI.com/reference/en-XX/help/370622J-01/lvrtbestpractices/rt_portal/

  Here's a page on the conversion of a desktop computer to a target RT:

  Good luck with your project.

• Best practice? Storage of large data sets.

  I'm programming a Client to access the customer address information. The data are delivered on a MSSQL Server by a Web service.

  What is the best practice to link these data namely ListFields? String tables? Or an XML file with is analyzed?

  Any ideas?

  Thank you, hhessel

  These debates come from time to time. The big question is how normally geet she on the phone after

  someone asks why BB does not support databases. It is there no magic here - it depends on what you do with

  the data. Regarding the General considerations, see j2me on sun.com or jvm issues more generally. We are all

  should get a reference of material BB too LOL...

  If you really have a lot of data, there are libraries of zip and I often use my own patterns of "compression".

  I personally go with simple types in the store persistent and built my own b-tree indexing system

  which is also j2se virtue persistable and even testable. For strings, we'll store me repeated prefixes

  that only once even though I finally gave up their storage as only Aspire. So if I have hundreds of channels that start "http://www.pinkcat-REC".

  I don't store this time. Before you think of overload by chaining these, who gets picked up

  the indexes that you use to find the channel anyway (so of course you have to time to concatenate pieces)

  back together, but the index needs particular airspace is low).

• Design by using NetApp's best practices

  I am preparing for my VCP5 and I read the new book by Scott Lowe. the book describes how the traffic should be isolated. your vMotion, vmkernal, etc., but in many organizations, I see the NetApp with some of data warehouses and a few LUNS to CIFS share LUNS. I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files? In freenas and openfiler forums, they stress is not to run their software in virtual machines in a production environment.   Physical separation would be better then just a VLAN? I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable if you have redundant switches on both sides VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  > traffic must be isolated.

  Yes, the network traffic must be split on networks separated for various reasons, including performance and safety.

  > NetApps with MON a few for data warehouses and a few LUNS to CIFS share.

  Yes, if you have a NetApp file server you can block-level storage server as FCP or iSCSI, CIFS or NFS file-level storage.

  > I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files?

  OK, you lost me.  Yes, you must separate the vMotion traffic to enhance the performance and because the vMotion traffic is not encrypted.

  I don't see where you're going for vMotion to a Windows file server?

  However, if you are referring to, why don't you your NetApp instead of Windows CIFS Server:

  You don't need to patch and reboot the NetApp at least once a month.

  Performance is better

  You don't need to buy a Windows license and then maintain Windows

  Snapshots.  NetApp has the best shots in the business.  When your Windows I/O high, or just typing box because it of Tuesday and removes all of your VSS snapshots you really wish you had a NetApp.

  > In the forums of freenas and openfiler, they stress is not to run their software in virtual machines in a production environment.

  Note that there are a ton of storage there equipment running as VMs and server NFS for shared storage, including left and they have been stable for years.

  > Physical separation would be better then just a VLAN?

  Yes, if you have the infrastructure.  When it comes to the first time I've seen reference you VLAN?  Are you talking about now the NetApp as the series 2020 with two network cards where you need to carry all traffic (managent, CIFS and iSCSI) through them via VLAN?

  Like this: http://sostechblog.com/2012/01/08/netapp-fas2xxx-fas3xxx-2-nic-ethernet-scheme/

  > I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable

  CIFS is nothting to do with SAN, vMotion or VMkernel.  CIFS (SMB) is the protocol used mainly by Windows file sharing

  > If you have redundant switches on both sides of the VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  You always want to redundant switches.  No single point of failure is the best practice.

• Best practices installation CARS in two areas of data center?

  Data Center has two distinct areas.
  In each area, we have a storage system and a rac node.
  
  We will install RAC 11 GR 2 ASM.
  
  For data, we want to use diskgroup + DATA, normal redundancy mirrored on two storage systems.
  
  CRS + vote, we want to use diskgroup + CRS, normal redundancy.
  But for diskgroup CRS + vote with normal redundancy, there are 3 LUNS and we have only 2 storage systems.
  In my view, that the third logical unit number is necessary to avoid situations of split brain.
  
  If we put two LUNS to storage lun #1 and the other for storage #2, what will happen when storage faills #1 - it means that two of the three disks for diskgroup + CRS are inaccessible?
  What will happen when all the material in the #1 box fails?
  Is the human intervention: at the time of the failure, which #1 area rises again?
  
  Is there a best practice for configuration 2-zone 2-storage cars?
  
  Joachim

  Hello

  With regard to the vote of the files are concerned, that a node must be able to access more than half of the files with the right to vote at any time (simple majority). In order to be able to tolerate failure of n files in vote, need at least 2n + 1 configured. (n = number of files with voting rights) for the cluster.
  The problem in a stretch cluster configuration, is that most of the facilities use only two storage systems (one on each site), which means that the site that hosts the majority of voting records is a potential single point of failure for the entire cluster. If the storage or the site where the files of n + 1 vote is configured fails, the entire cluster will go down, because Oracle Clusterware will lose the majority of the files.
  To avoid a complete cluster failure, Oracle will support a third vote file on a cheap lowend, standard NFS mounted device somewhere in the network. Oracle recommends the file NFS vote on a dedicated server, which belongs to a production environment.

  The white paper below allows you to accomplish:
  http://www.Oracle.com/technetwork/database/Clusterware/overview/grid-infra-thirdvoteonnfs-131158.PDF

  Also with regard to the configuration of the vote and OCR (11.2), when you use ASM. How they should be stored?
  I recommend that you read:
