the memory of the VM concept

in the summary of a virtual computer, we can see three memory settings, for example: memory overhead(99MB), memory usage(72MB), memory usage(564MB) host comment, what is the meaning of them?

Explanation of the Dragon is about right. There are a lot of technical details which are difficult to transmit through the forums, it would be nice if someone put together a little demonstration flash of operating memory allocation & free lists, balloning, pinning, etc.. There was a demonstration of fantastic at VMworld 08, session TA1401, "Understanding host" and Guest memory usage and other memory Management Concepts by Kit Colbert. He did a great job explaining the relationship between the virtual memory (app), the physical memory (os) and the machine (vmm) memory... How the pages are allocated and followed everyone later... etc.

Unfortunately, I don't think that the slide deck is publicly displayed. It should be. (Note: If you attended VMworld, you can download the slides w / audio.)

Hardcore technical details can be found here, if you are looking for an official VMware doc: http://www.vmware.com/pdf/usenix_resource_mgmt.pdf

  • Query on the Oracle Concepts: advantages of the SAMS

    Hello

    A query on the Concepts of the Oracle, specifically on the benefits of the SAMS.

    While I am able to understand "Simplified Administration" & "Increased Concurrency", can someone mention this in simple terms:
    • Dynamic affinity of space to instances in an Oracle Real Application Clusters (Oracle RAC) environment.
    I guess I know what Oracle RAC, but what is meant by 'dynamic affinity of space bodies "?

    Kind regards
    Ankit Rouault

    When choosing a path of navigation through SAMS bitmaps, your session uses an algorithm (which I believe is a hash algorithm) which includes your session identifier. It is unlikely that many sessions will seek the same part of the bitmap and therefore insert into blocks of same of the segment, reducing contention between sessions. In a RAC, the algorithm also includes the instance number. This should mean that sessions against different instances will tend to get different parts of the bitmap image, reducing the contention between instances.
    I am of course open to correction on this.

  • The new Concept of Media Sync blackBerry smartphones

    Hello

    I love my BB and recently upgraded to the latest version of the desktop management software. This all sounds good and is visually very significant improvements... but the Media Sync feature unusable.

    I'm not particularly fond of the new way of media sync (comes with Desktop Software 6) with your phone. Where the hell is Roxio Media Manager? This new method is not enough and downright unusable. I will now add media to my phone using my BB as a flash drive. How do you manage what's on your phone and who decided that this way to 'sync' is the best way to move forward?

    Can I come on down to Desktop Manager version 5? This is somehow horrible, HORRIBLE to get media on your phone.

    Hello.

    I fully agree with your statements. Aparently, it's the way RIM wants manipulate us our media and contacted simply indicate that it is the designed functionality.

    I guess with all the negative comments they get, they will send an update that offers more flexibility, including bringing the ability to manipulate media files that are encrypted.

    You can return to 5.0.1 in 6.0 unistalling then reinstalling 5.0.1. The software is easily available in the support section of the Web site.

  • I have a question in the basic concepts of OBIEE

    Hello
    I'm prasanna Undapalli.I have question, can u please someone solve this problem.

    Can I use a backend of OLTP database to create a dashboard?

    Thank you inadvance.
    Prasanna

    Hello

    Technically you can use OBIEE with OLTP as well. However in real-world OLTP-related scenarios makes it difficult for OBIEE create OLTP star schemas. OBIEE is also an engine to run the analytical queries, while in most cases the queries generated on OLTP patterns are operational in nature. Best option is to use BI publisher and finish with OBIEE when querying against OLTP.
    OBIEE works with any database if you make do. If you want to follow best practices, its recommended to use with OLAP systems. Once all the OBIEE analytical reporting tool and OLAP databases are designed to the requirements of statement. For its always advised to use OLAP for better performance and more analytical of OBIEE.

    Bottom line, you can use OLTP with OBIEE, but performance will be a problem (not recommended).

  • The operation failed because no appropriate resource is found

    Hi all

    I installed the version of piphany OVF vCloud on my ESXi. I managed to install all compontes, including organzization & VDC.

    No error spoted in my settings.

    I'm alwayes when you try to run vApps/VM this error:

    -L'operation failed because no appropriate resource was found. The operation failed because no appropriate resource was found.

    What resource is missing? I have downloadable storage... so what is the case.

    I don't know where to look... I tried to change the virtual machine hardware settings, has not solved the problem.

    Thank you very much.

    First off the coast of never change in vCenter which controls the vCD. It can really mess up your environment. I made this mistake when testing vCD 1.0 and 1.5 to try to match some of the things we were doing in the laboratory Manager.

    Then, don't worry ESXi nested because it's the same concepts, once you get the operational environment.  We run in our test environment of this way as well and didn't have any problems.

    What resources your ESXi (those nested used by vCD) hosts have in the measure of the number of vCPU (and speed) and the amount of memory?  How are other virtual machines running on them (such as your cell of vCD, vCenter, POSSIBLE, etc...)?

    As much as your benefits I guarantee that many resources to the virtual machine.  In our software development environment we guarantee only 10% of CPU/memory and we validate vCPU speed to the ESXi servers.  Looks like your screenshot, you have only capacity for 3.95 GHz but you have allocated 3.5 for the first virtual machine. At that time there you won't able to launch virtual machines more.  If guarantee you only 10%, you will be able to turn up more.  Given that you test just the product I wouldn't worry CPU contention at this point.  When you get into production, you will have more resources to fix this.  You are other options is to add more vCPU to your nested ESXi hosts.

  • Why the latches is if the mutex are better?

    Hi all

    I'm trying to understand the mutex and latches, also searched the forum and read other messages.

    My question is, almost in each paper said: mutex are faster, less false assertion, less size etc... also are locking latches a block of memory, but each object has its own mutex.

    two of them are nice locking mechanism, which is OK but if the mutex are better why latches are exist? What is advantages of locks?

    Mustafa KALAYCI says:
    Aman,

    I'm really starting to feel like a fool. each different answer changing my understanding of locks and mutexes.

    Isn't fun?

    When started this topic, I thought that the clasp and mutexes are both a locking mechanism that during a process of reading in or by writing to something a piece of memory, process locked this field and make it's own, it's lock is a lock, or mutex (it is also very close to description of University oracle performance tuning training manuals).

    In this book, its very clearly explained that latches may present a statement false . For example, when you see a Cache library top 5 events, you should interpret, this is a good thing or a bad thing? Without access to it, you can't search for the library Cache hash strings and cannot come to know that the slider required on your part is there or not? That means, until the moment that you do not have the hand on Library Cache, the decision to go for a hard or soft analysis is not possible and that is waiting for the library Cache lock, is of no real use at all. This is a false assertion and Mutex can help minimize this. Good read this page completely and with a little more attention and you need to understand.

    then I started to know the difference between the lock and the mutex. at first, I thought that HLDAA and mutex concepts belong to the oracle database, but I realized I was wrong. It is a technique of joint programming for shared resources.

    This isn't a concept of programming but the mechanism for the protection of the integrity of the structures of memory.

    I'm not sure that the lock concept is nowhere else or not in addition to oracle. But the notion of Mutex is already there in the operating system concepts.
    http://en.Wikipedia.org/wiki/Mutual_exclusion

    documents almost I read told me that mutex are just better and I'm just curious, if mutexes are better, why are locks used.

    I mentioned several times the answer to this, the concept of lock is a proven concept and is around for many years in oracle. Simply because the Mutex is better, this does not mean that Oracle, the next day, everything would change and will begin to deploy the mutex. You realize that Oracle code isn't just 10-15 lines that its really possible to change in a short way.

    When I run a query, first oracle will search this library if cached query cursor can not found create it there and then start interviewing research data. While the oracle process research to the cursor when it exists, it crashes a block of memory that it is currently reading in the library cache. After that, he will start looking to the data buffer cache. in seeking the data block, each block will be locked again while reading process and released when he finished reading.

    in which level a mutex and latch will be created and released. It might be easier if I get an example like that.

    for the moment, I think that mutexes and locks are algorithms to protect the wrong again... maybe shared structure.

    They are different ways to do the same thing, latches are something you need to wait, revolve around the CPU to get their hands on them. Mutex, are much faster, can be acquired more quickly and released more quickly as well.

  • How can I parallel 2 2 queries differ from the DB?

    The situation: I have a function, where I create 2 queries dynamically. Queries refer to two different bases, which are bound by dblink. And then I just union by the "UNION ALL" clause. After that I have exec that together interrogate them. Then I assign the results to a sys_refcursor. And the function returns a cursor to my external application.

    Question: can I run the execution of these two queries in parallel mode and how? I think that the execs 'UNION ALL clause "the first part of the first and the second union. Any help appreciated.

    A cursor is not a result set. A cursor lies in the shared SQL pool and consists of submitted SQL source code and this code in the format "analyzed and compile ' (aka an execution plan). A slider is like a program. A cursor with bind variable is as a program with input parameters.

    The cursor or the program is executed. It copies data to the appellant when the appellant says the cursor fetch/get the next series line out.

    There is no result set created and stored somewhere in the memory of the (limited) server. Take a look at the view of Oracle® Database Reference (as V$ SQLAREA) on the sliders and container.

    Question: can I run the execution of these two queries in parallel mode and how? I think that the execs 'UNION ALL clause "the first part of the first and the second union. Any help appreciated.

    From where? PL/SQL? Or a Java client?

    You will need to evaluate this approach to parallelising of treatment. It can only increase the complexity and provide little benefit performance.

    The basic concept is that the thread principal (or process) will be the consumer of the data - and that children threads will read data from the remote databases and write to the data stream that the mother consumes.

    In PL/SQL, this can be done using queues in advance - where 'children' (started as background work processes for example) spooling the data they retrieve from the remote cursors and the parent removes and processes these data.

  • How to recover the button orange "firefox"?

    I use Firefox 30 (PC) and the new conception of love, but I miss the orange "Firefox" button. Is there an add on that will recover, without replacing the new theme australis? Thanks for your time!

    Note that the classic Firefox menu button will be orange if you place it on the tab bar or on the title bar as you can see in the Options/preferences of MCGILL (click on the application button color selection button to open the drop-down list).

  • Why remove the only element used, the bar addons?

    Why their v29 change log done said 'additional options', when the only thing that most of us see is deleted the options, including the most widely used single section: bar of the addon? I don't want to install an addon to display the bar of the addon, which is present from pre-Firefox Mozilla days. So why delete the single most used item? Done the previous CEO Pro-life as it too and the new direction isn't that? Looks like Firefox is going backward, not forward.

    NO.... I'm not citing specific examples, but put MORE junk at the top after we are inundated with having TO use the tabs (which are redundant copies of windows below only cramped in to the top at the same time bar) bar, now I have 22 size icons and even drop my space window of text buttons lower in my workspace. It is not that the buttons/icons/addons don't work. (I swear to you that I don't know how people who work in support might need these detailed explanations) It is the fact that, to keep the premium screen, space open, to crush the tabs windows and Firefox destroyed this option. So we went with opening and closing of the bar of the addon whenever we need an add-on. Not to mention the addons as a certain addon Instagram that shows when new photos have arrived, or my safety bar that shows how much the ads and the sites have been blocked, as well as a mouse on display them separately in a concealed popout. Firefox developers are so stuck on their own crud they REALLY think that everyone has and uses on a Galaxy phone apps and crunches all icons like a 13 year old? Those of us who are older, more mature and use addons for something else than sharing photos... (as my Google Voice addon that does not work now to accept calls to open a bar and clicking on the icon until it accepts the click, oops dropped call or went to voicemail because you did not 3-ring)... Phone, Flash development, download videos from websites, eBay, Amazon shopping sales, torrents and each model of business platform has their own INHOUSE addon. You DESTROYED, DECIMATED, no. the model of less clicks is longer, for A SUPPOSEDLY SLIM BROWSER SIMPLIFIED! It's no wonder Execs of Firefox are clueless. Block us who care, our usage patterns and thus only the details on the use of the games for children under 15 to noticed by telemetry from FF.

    The basic concept, delete something, at least that replace you it with something equality in employment and work.

    Make users create a toolbar addon to replace the bar of the addon is stupid! Pointblank and simple.

    Add more clicks to get to the new bar addon was stupid and dumber still was the destruction of a top level bar with a value of the space in the window by the new addon bar be an addon or a creation of the user between the Bookmark Bar and address bar. STUPID!

    Finally, why is Firefox simplify anything. It is at the discretion of the user during the construction of its browser him or her self. That's what means be a modular browser. It is not Mr. potato head with only 4 types of eyes, nose and mouth. It's supposed to be a free canvas to work and create our idea of art works.
