BDB does support several parallel readings?

I wanted to know if there is any support EI for several parallel readings?

for example, we want to read the information on the 10-15 set customer ID?

I provides any kind of API for bed in bulk? (We use the DPL package in BDB for primary & secondary index)

Thank you

Hello

Yes, I read in parallel when hold the following conditions:

+ Two records have different low internal nodes in the Btree, that is to say, their keys are not close in value. By example, if you have a large data set and you read keys with random values, this condition are usually held. If you read two keys that are adjacent, the condition usually won't last.

+ The file system supports simultaneous playback. I use methods of file system standard for playback.

If the records are in the cache, only the first condition applies.

  • Creative cloud does support several personas?

    I have a creative cloud by labor account. I also want to do personal work at home with a separate set of shared libraries, etc. I guess that means I have to create a separate account of the creative cloud. It is fine, but what happens if I want to use a common (like my iPad) device for personal and professional projects? Will it connect constantly in and out of each CC account? Or, CC does support several personas so I can go back without logging in? Perhaps I could deal with logging in and out of a single device, but if I use several devices in my workflow (telephone, laptop, Tablet), it seem unrealistic.

    On a similar note, if I start a public Behance portfolio with my CC work account, lose access to it if I change jobs?

    What is meant by Linksys with ADSL support IP TV?

    Just spoke with the guy from Linksys. WAG320N really does not support IPTV. And more Linksys not all router ADSL with IPTV (line new WAG). In my opinion, it is not good for brend like Cisco. I was belived in Cisco. But now, I'm very angry. Before buying I cannot find any information on IPTV on Linksys website. Announced just as «...» Ideal for applications focused on media like streaming video, games and voice over IP telephony... ». Now... I'm not sure it's true... And maybe another stanza on Linksys web is just a myth.

  • Photoshop Fix does support multiple layers?

    The new mobile application does support several layers just like old APP?

    Hi there, noahg!

    To do this, but maybe not in the way you can imagine. Fix changes are saved in separate 'adjustment layers '. When you send it to another program, Photoshop for example, you are able to see the adjustments in the layer panel (unless you group your adjustments within Fix). For the moment, you cannot add other layers of the photo, but you can send to mix and add additional layers here.

    Let me know if it helps!

    See you soon

  • Satellite A105-S4284 does support Windows Vista?

    A105-S4284 does support windows vista? or the drivers are not yet ready? Is vista capable PC, I know, but several times I tried to install vista RC1 and it hangs up in the middle of the installation:(s'il vous plaît aidez_moi.)

    Thank you

    If it s a laptop capable of vista then I see no reason why the laptop doesn't have to support Windows Vista.
    It of a fact that, this time no Vista drivers are available on the Toshiba page. (I put t found any)
    I guess we will be able to download the drivers in the next few weeks.

    PS: I installed the RC2 release of my camera and it works without any additional driver. Only the wifi card does not work, but I can live with them

  • Closure of a state machine in queue event with several parallel loops

    I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

    I look forward to any comments on my as well code, if someone is willing to offer it.

    My program needs:

    If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

    Architectural details:

    The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

    During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

    In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

    HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

    I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

    I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

    Thank you!

    First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

  • Chrome still does support OSX 10.9.5

    Chrome still does support OSX 10.9.5?

    According to the page of the Google Chrome browser, this version of Chrome is said

    in support of Mac OS X to present 10.11.5 10.9.5. Chrome - the Google browser

    However, the questions and problems that Chrome continues to show Mac users,

    indicate that it is not a wise choice for Macs.  Users have found Chrome to be

    a resource eater, which affects the performance of OS X.

    We'll find a better browser to Mozilla Firefox; also Safari is always supported by

    Apple at the moment (my OS X 10.9.5 a recent version of Safari; I prefer Firefox.)

    A few others are probably OK, that won't cost you performance elsewhere.

  • Firefox does support multiple lines or bands of tabs

    Previous versions of Firefox are supported several rows, but I can't information that allows me to do with this version, P.S. I am using a new computer with Win 8, but settled just a standard Firefox.

    You were previously using the Tab Mix Plus extension? One of its features is to allow multiple rows of tabs.

  • HP J6450 really does support WPA Wireless encryption?

    I just bought a new J6450 yesterday, and when I tried to install it as a wireless network my SSID does not appear (even if the PC just next to the printer is connected to my network).  Even when you enter the SSID manually the installation process does not recognize it. There are other SSID in the region that appear during the installation.  I confirmed that my router is broadcasting and the printer was 4 feet from the router, so I know that is not due to the intensity of the signal.

    Details of router - NetGear WPN824v3, configured for either 802. 11B or 802.11 g (auto mode), WPA encryption

    The only thing I noticed during my research it tonight is the SSID that was listed when installing 2 are encrypted and most of the HP support info and documentation related to the wireless configuration seems to refer essentially to WEP.  If the HP J6450 really does support the WPA encryption, and if so, does anyone have ideas for troubleshooting why it does not recognize my router?

    Thank you.

    Connection to the router under the admin user, then "Wireless settings" page is a Mode setting and the default value is "Auto 108 Mbps.  Using the arrow in the drop-down menu, change to "b and g" then set the channel to 'Auto' and save the configuration changes.

    Hello

    These information are not known to me, and especially if you want to buy a car for you laptop, you must first call the Toshiba authorized service provider for more information on compatible players.

    There is also another possibility to find out what the laptop supports parameters.

    After this diagnostic procedure, you need to know more details about the installed drive and you must buy the player that supports the same specifications

  • Satellite L500 does support VMX?

    Hi friends,

    I am using Toshiba L500 series, I installed the 64-bit version of Centos 5.3 in my computer successfully, but I want to install another version of centos5.x in the Virtual Machine box, but it was not installed, in the middle of the installation of the Centos 5.x 32 bit it was struck, then please say one, it is very important to me...

    Thanks and greetings

    Vnvs Swamy

    > Toshiba does support VMX?
    Maybe it sounds silly now but Toshiba supports own products only. With other words Toshiba must offer support for hardware and software pre-installed.

    If you use a third party software and there is a problem, that you should contact the first software company to see what they say on this subject.
    Toshiba has nothing to do with Centos 5.3 and VM box. You can call the hotline of Toshiba and ask, but I'm 100% sure that you will get the same answer.
