How to config a cache shared for several environments with the C API

How to config a cache shared for several environments with C API?  Like Java edition. Chapter 2. Database environments

I want to open the large number of databases, at least 10,000. But as the counties of open databases increase, the db-> open become very slow operation. It took almost 2 hours for 10 000 databases.

So I try to distribute these databases on multiple environments (for example, 5 envs). And to improve the efficiency of memory use, I want to share cache between ENVS.

Hello

We do not support the cache sharing between different environments as you mentioned.

We have tested the case of the opening of 100 000 databases, see the number that you have encountered, we will check what is happening.

Kind regards

  • [After Effects] How to use "Convert Vertex Tool" for several vertex at the same time?

    Hey guys,.

    I used the "Convert Vertex Tool" to create a curve on a step of stairs and by mistake it curve all the point of my staircase which is what I wanted to do but point by point. I didn't know it was possible to point (s) at the same time.

    And now I keep it again. I want to convert all the points as a curve at the same time.

    If someone has the magic shortcut, please let me know.

    See you soon.

    It's all using the right tools.

    1. Select the layer with the path
    2. Select the tool pen (g)
    3. Press and hold Ctrl/Cmnd and place the cursor on any part of the path to select - you will see a solid filled small arrow
    4. Release the Ctrl/Cmnd key and move the path tool, so you can drag a selection around the verticies
    5. Hold Down the Ctrl/Cmnd key to reveal an arrow small white selection
    6. Drag your selected verticies
    7. Release the Ctrl/Cmnd key and press the Alt/Option key to reveal the convert vertex tool
    8. Click on any vertex to change linear to Bezier or vice versa

    This allows you to convert all the selected vertices. You can't click and drag, but you can convert it to a symmetrical set of Bezier curves.

  • Can I have several structures with the same case of event event?

    Hello

    I do an application which reproduces the front of the power supply HP6675A. To do this, I did a machine to States with different States

    (initialize, measures, voltage, current, ocp, ov, store, recall, etc.). In each State, should have a structure of the event that attracts the events of the buttons, as for example: If the current state is the voltage mode and the current button is pressed the next State will be the current mode. For this purpose in each State of the state machine should be the same structure of event with the same events.

    My problem is that the Vi does not work properly when I have several structures with the same case of event event. There are some possibly to do and how? Or is impossible to have several events? I read a few posts, but I can't find solutions.

    Any help is appreciated.

    Thank you very much.

    In general, you should have 1 structure of the event in your VI.  In your state machine, the structure of the event should be in "pending" status  So you will probably start in the State of the initialization and then spend idling.  Then, the user presses the present button.  If your state machine should then, go to the current state and then return to Idle.

  • I've had several accidents with the blue screen noting CRQL_NOT_LESS_OR_EQUAL

    Hello.

    Here are some files dump of my crashes: http://cid-5cfec8d823e42bd3.office.live.com/browse.aspx/.Documents

    Here's what happens:

    Since June, I've had several accidents with the blue screen noting CRQL_NOT_LESS_OR_EQUAL (Yes, CRQL, no IRQL level), and they are producing at closer intervals. I also notice some changes of office and some sounds to open files that are not have happened before. I run antivirus and malware and found nothing. I did a disk cleanup and defragmentation.

    I also tried to install via Windows updates and everything seems to date. I ran Windows Memory Diagnostic tool, and it found no errors. I ran Windows Startup Repair and got the following note:

    Root Cause found.

    Thank you in advance for your help!

    Hello

    Uninstall Faultwire and look for the codes manually as needed. The link to troubleshooting blue screen
    page will show you how to get them.

    How old is the system? A real computer store (not the leeks and glances at a Best Buy or other large surfaces)
    Stores) can help to give a proper diagnosis of the machine.

    You can use Safe Mode - repeatedly tap F8 as you start - use to back up your data in a redundant
    way off the machine. Then re-install Windows that "might" help if the problem is software partner.
    Of course, you will need to reinstall your programs and restore the data in the machine.

    Although there are a large number of errors there could be a cause for all. Try to remove ALL power and
    reinstall all the memory cards and cables (at both ends, when possible) - actually delete and replace.
    do not just tight. Clean the dust bunnies (of course those who are for a PC - for a laptop to ensure that)
    the vents are clear). Try using a small fan blowing through the vents to see if heat is a problem.

    Update key drivers - display/video, NETWORK card and WiFi (network), sound (do not forget to check the sound card drivers
    What update because they will often rollback then repeat the installation until the correct version appears), modem
    and all of the other major features, you could have as 3rd party mouse or keyboard.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
    each driver in the list, additional useful information is displayed: load address of the driver, description,.
    version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager
    http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.html

    If you update the drivers manually, then it's a good idea to disable the facilities of driver in the Windows updates,
    This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause
    questions. If updates offers a new driver and then hide it (right click on it) and then go look for new ones
    manually if you wish.

    How to disable automatic driver Installation in Windows Vista - drivers

    http://TechNet.Microsoft.com/en-us/library/cc730606 (WS.10) .aspx

    NOTE: Often restore audio drivers to check the version after installing and restarting is
    see if the version you have installed is there, otherwise repeat the installation - restart until it is. This may take
    several tests according to the recommitments how much he makes.

    Hope these helps.

  • Several files with the same name.

    Cannot publish to Business Catalyst because of a fatal error, where it is said "why do we have several files with the same name?  The website and all its contents have not changed in more than a year with the exception of minor changes to the wording so unable to understand what the error is encountered. Are there not better misdiagnosed at one point less for the files in question.

    The problem is the result of a mixture of case-sensitive and case-insensitive between how files within the .oam are put into interaction with and what is written in the muse_manifest.xml file during a re - download full compared to an incremental download.

    If all .oam packages files are tiny and the original .oam were replaced in Muse with the all new tiny .oams, then you should select Upload: publish all the files in the dialog box Options. From there, forward publication of incremental changes should work without errors.

  • Return of the mistake of MUSE: why do we not have several files with the same name?

    Well - I thought I had all this worked and fixed, but I met the download error 'Why do we have several files with the same name' once again.  (I downloaded all the files several times today in order to 1) works the way it worked the last time and 2) get an OAM file that is not loading for some reason any load again and the download takes about an hour to transfer all the files manually.

    To recap:

    (1) an option "Upload only modified files" returns the 'Muse has encountered an error and closes.  Why do we have several files with the same name? "error just as before.

    (2) a full download will work but takes forever and is NOT a substitution for work changed files option.

    Please advise with possible solutions!

    -Dave

    Is it possible to have two .oam different files in different folders on your computer where the .oam files have the same name? I'm theorizing that there may be a bug in the treatment to ensure the folder created for a .oam placed on the server receives a unique name, particularly in the case of a partial update of the site on the server.

    Please send us the .muse file and all the files in .oam related to [email protected] along with a link to this topic for the context so we can attempt to reproduce this error and isolate the root cause. If files are larger than 20 MB, you'll need to use a service such as Adobe send & Track, Dropbox, creative cloud, WeTransfer, etc. file sharing. Thank you.

  • XOQ-01950: Cube contains several BuildSpecifications with the same name.

    Hi all

    When executing the option to maintain Cube he throws under question: any clue?

    XOQ-01950: the AWCubeOrganization for cube 'NN_OLAP_POC. MARKET_SALES_CUBE"contains several BuildSpecifications with the same name.

    Thank you
    Exq

    This error should show only upward when you create a cube (by importing XML), not when you maintain. So, I'll assume that's what you hear.

    If you are importing XML that references an OLAP object that already exists, whereas the new definition replaces the old. The only exception to this rule is the BuildSpecification object. This kind of object is called, but it does not follow these conventions (for reasons of disorder of implementation). If you import the XML code that has a BuildSpecificaiton with the same name as one that already exists, then you will trigger the error you see. Here is a relevant example of XML.

    
     
    
    

    The solution is to remove this section from the XML before importing it.
