Size limiting the front of a nearby cache?

For some reason, I got it in my mind that ahead of a near cache used SoftReference or WeakReference to hold local objects so that they could be trimmed by the virtual machine during garbage collection if the pile has been requested by memory. I don't know where I got this idea, but certainly, it doesn't seem to be the case.

Just so I'm clear, is - a size must explicitly limit the front of a nearby cache?

That's right - the front cache near holds real references to keys and values so they won't be garbage collected. Size must be limited as described in the documentation here http://download.oracle.com/docs/cd/E15357_01/coh.360/e15723/appendix_cacheconfig.htm#BABDHGHJ LocalCache caches

  • Difficulty the front Dimension of the array, but allow the user to change the size of the array

    Hello

    I know there are a few other posts on table and scroll bars but mine is a little different. I want to have the physical size of the fixed table control and allow the user to change the size of the array as required and a scroll bar if the number of elements exceeds the specified physical dimension. I wouldn't mind if, at the end of the scroll bar, the user sees an uninitialized element.

    Thank you very much

    Hello

    The problem I have with the property Num Row node is it seems to replace the scroll bar. Whenever I try to change the line number, the table automatically resizes its physical size on the front and the scroll bar has no effect.

    However, I solved the problem by taking row completely digital. I just said if the table size is > to a constant value (i.e. 3), add a scroll bar and my front panel dashboard to be a size larger than what the value of this constant is size. Once I begin to add values in sequential order and I get to the fourth value, the scroll bar is added and the scroll bar has a feature where it adds an element of null for you, so if I fill this null element I just increased the size of the table and another null element appears underneath.

    Thanks for the help

  • Reducing the size of the Panel complete front to adjust the screen resolution of 1024 pixels / 786 pixels

    Hello.

    I designed the app and now I found the screen resolution required is 1024/786. I have a lot of orders and indicators and very worried that the façade will lose his eye and he'll take a lot of time to be set for each control and text.

    I wonder if this is the way I could shrink the size of the front panel so it automatically reduces the size of each control and indicator and it fits well in the required resolution. Any ideas?

    Thanks for help

    Kind regards

  • Error in replicated cache (lazy write) led to the OOM error in live cache.

    We have an application that has a live cache and the data in the live cache is replicated on a cache of contingent. Result cache is implemented by enabling the cache write-back cache direct store.

    The problem is if the cache of the quota goes out of memory, direct cache fails to send data in the cache of contingent and keep requeuing data. Also the cache nodes fails to connect to the cache quota live, they keep on Retry to connect nodes from the cache immediately, this has also led to several exception on direct cache cluster. If the situation persists for cache some time then direct also fate memory and don't fail to answer.


    In this way contingent cache actually creates a direct cache problem. We want to ensure that if there is a problem in the cache now, this should not change the live cache. Any suggestion?

    Can you maybe post the details of configuration for these two caches?

    Maybe size limiting the possible cache will solve your problem?

  • How to change the size of the protection GPT Partition

    I have a MacBook Pro (mid-2012) with 250 GB SSD. Next to OSX, I used BootCamp to install Windows 8 and then improved to 8.1 Windows and Windows 10. Everything worked well to 8.1 Windows but when I upgraded to Windows 10, she could not make backups of image. Support Microsoft informs me that it is because the size of protective Partition is too small and must be increased at least 300 MB to 200 MB to reach its current size. Here's my current disk configuration:

    View of MAC:

    #: NAME SIZE TYPE IDENTIFIER

    0: GUID_partition_scheme * GB 251,0 disk0

    1: disk0s1 EFI EFI 209.7 MB

    2: Apple_HFS Macintosh HD 100.0 GB disk0s2

    3: disk0s3 Apple_Boot Recovery 650.0 MB HD

    4: Microsoft database BOOTCAMP 150,0 GB disk0s4

    Windows display:

    1 - protection GPT partition Partition - 200 MB

    Partition 2 - d: Partition first, HFS - 100 GB (this is where OS x is installed)

    Partition 3 - primary partition - 620 MB (no idea what it is and how it got underway)

    4 - C: partition BootCamp - NTFS - 139,83 GB

    The OSX partition has plenty of space available (61GB). My knowledge of Mac OS x is very limited. I don't want to do something that could make the system unbootable or require reinstallation of the operating system and its applications. How to resize this partition to provide a space for the GPT partition resizing?

    Thank you for looking into this.

    It seems that what Microsoft calls GPT partition protection is the EFI partition in OSX. Wonder why its size limits the ability of Windows 10 to backup image.

  • How to get the size of the binary cache from code

    Is there a way to get the size of the cache in bytes? (size() method retrieves the number of objects, as when the size of the cache is limited in configuration by unit-calculator 'BINARY')?

    Hey Meir,

    As Wei said that there is a JMX exposed for each cache bean and you can just summarize the units attribute. There is a second attribute called UnitFactor that you also use to be precise. In most cases, UnitFactor will be 1 but the appropriate calculation of size in bytes of a cache is

    Units * UnitFactor

    Second, you ask this cache across all members of storage and summarize the results. This will give you then the size that includes the key and value but not take account of all sizes to index.

    An easy way to make JMX requests within the coherence is:

    String cacheName = "";
    MBeanServer mbs = MBeanHelper.findMBeanServer();
    Set names = mbsc.queryNames(new ObjectName("Coherence:type=Cache,service=*,name=" + cacheName + ",*"), null);
    
    long totalUnits = 0;
    for (ObjectName name : names) {
        Integer units = (Integer) mbs.getAttribute(name, "Units");
        Integer unitFactor = (Integer) mbs.getAttribute(name, "UnitFactor");
        totalUnits += (units * unitFactor);
    }
    System.out.println("Total Units = " + totalUnits);
    

    There are other ways to get the size too.
    You could write an aggregator that calls BinaryMemoryCalculator.INSTANCE.calculateUnits with the binary key and the value of each entry that went. This would not be very effective, but would be useful if you want to calculate the size of a subset filtered registration.
    You could write a remained that gets the support of the cache card you want, cast to LocalCache and then call the appropriate methods to get unitfactor and units. You must run this invoked on each Member of storage.

  • How to change the size of the Cache of the Turbo on Satellite P100?

    I have P100-138 (PSPA3E) with 2 GB of memory.
    But I don't know where I put the size of the Memory Cache of the Turbo.
    I have GeForce 7600 dedicated to go with 256 MB of Ram, but I more than 256 Turbo Cache memory.
    I can't find this option in the BIOS v3.8.

    Are you sure that something like this is possible to do this with a laptop graphics card? I'm not 100% sure, but this option on P100 is unknown to me. Generally these characteristics are described in the document s user manuals.

  • Y510P - How can I check the size of the SSD Cache?

    Hello

    I just took delivery of a Y510P but don't see anywhere how I check the size of the SSD Cache.

    The laptop should have come with an 8 GB SSD Cache but how to check this?

    Thank you very much

    Jon

    Brayjd, I, too have just received my Y510p, and after reading your post, became curious as well. After trying all the same things you did, without any good results, I went into the Device Manager and got the hard drive part number and google it. It turns out that mine is a hybrid SSD/HD with a SSD 8 GB cache built into the player. A hybrid has the SSD completely autonomous in the HD itself and requires no external software to run. That's why we have found no information on the size - for what is the rest of the computer is the SSD is invisible. Try Googling the part number of the hard drive. I hope this will answer the question for you, too.

  • The front panel scroll, based on the size of the monitor

    Hi guys,.

    I built an exe file of a VI on a labview having machine so that it can be run in another has no labview. The machine where I programmed the VI has a large 22 "monitor and so I put on my face as a result. The machine that will use the exe file has a screen size of 15 ", and some elements of the front panel are not accessible if I make an enlargement. However if I don't maximize the screen I can move the window to the edge and access controls. But it's so heavy. Is there a way I can add scroll bars to the VI while I can scroll the front panel?

    Thank you

    Of course.

    Scrolls bars are something that you can turn on (and are normally enabled by default) in the dialog box properties VI of VI.

    In addition, it is usually best to design your sign before and that it is effective for the smallest screen size you expect that it runs.

  • adjust the front panel of the screen size and re - position automatically objects on different systems

    Hello, I designed a vi which contains 5 led is placed at the centre of the façade that occupies the entire screen and 4 corners. However, this vi should be used on different systems, with different screen sizes. But on each screen, I'll need the size of the cover = size of the screen and the light to be placed in centres and corner of this new size of the screen automatically without manual operations and positioning bieng made every time. The option of resizing will perform this task completely or I have to go to some other techniques?

    As far as I know, what you want is not easy to do but it's doable but you have to do it programmatically (no adjustment of Labview). Here is an example for only 2 LEDs, but I guess you'll be able to make it work for your other LEDs.

    This VI maximizes the front and then positioned the 2 LEDs in the Center and top right on the race. LEDs are positioned according to their own corners left, not on the basis of their centers.

  • Efforts to control the size of the roaming profile Cache does not properly.

    We run a RDSH R2 2008 environment and we have set the maximum size of the Cache size to roaming profile for 26 GBS, but our roaming profile cache is never fall below designated size limit.

    We see evidence that lsasrv with actually deletes profiles that he scored as older and it will work four to five times, but the documentation suggests that it will continue to operate until the volume is less than the specified cache size, and our does not do that.

    We do not see anything to fix or adjust and find having to police manually servers to keep enough free space to accept connections.  If we don't keep our guard, users get connected with a local profile and the REO event will show that profile has not been charged because of insufficient disk space.

    Any suggestion would be appreciated, as we struggle with this one problem in a deployment by also wonderful to RDSH.

  • Can I manually set the maximum size of the thumbnail cache?

    I notice that in a folder with a large number of photos, there seems to be a limit to how much stored thumnails. If I quickly scroll the I get to a point where I have to slow down and wait for the thumnails to regenerate. I wish I could store all thums so I can go to any point in the subdirectory and see them with no delay (the whole point of a cache). I have 4 GB of RAM so I don't care if it uses a fair bit to do this. Y at - it a key option or the configuration of the registry to set the maximum size? I have Vista Home Premium x 64.

    Hello old giza,.

    Thank you for your response back!

    Except there is no way to increase the size for the thumbnail cache.  You are able to clear the cache and I saw on third party internet providers that offer this possibility.  But the operating system is not an option to increase.
    Maybe if you can give more details about what you're trying to do we can get to the best situation.  Please let us know status.  Thank you!

  • Limiting the size of data that can be loaded up via BES (JSR - 172 or kSOAP2 is used)

    Hi all

    I want to up load data from the device to the application server. (via BES)

    I use JSR-172 or kSOAP2 high-load it.

    Is there a limitation in the size of the data that can be loaded at the top?

    Hello

    as far as I know, they're just the protocols/utils. They help you define the message format, the specification on how you are going to write/read data and tastes. so I think that all this goes down to the http.

  • increase the 'size of the cache pending' of our cube ASO to capture whole database in memory?

    Happy new year everyone,

    We want to take full advantage of our 54 GB of free memory on our server Exalytics X 4.

    From this site, I read more in anticipation of the ASO cache size will reduce the disk i/o.

    The default / .dat file size of data from our database of the ASO is 9.9 GB with more 100 million cells entry level.

    We should increase the 'size of the cache in waiting"our ASO to 9.9 GB cube so that the entire .dat will be cached?

    Thank you.

    ===============

    PS. Here's what I found in ASO Tuning white paper, which seems to recommend 512 MB or 1 GB.

    ASO cache size has an effect on the performance of loading data. For

    small databases with cells of entry 2 million or less, the default

    ASO cache size to 32 MB is sufficient. For a larger database

    with 20 million cells, 64 or 128 MB of cache is more appropriate.

    A database with 1 billion cells or more, the size of the cache can

    be placed as high as 512 MB or 1 GB if memory permits.

    Put all of the memory base looks really cool, but my experience is that in most cases it is not necessary. In my experience, the benefit of the ASO cache decreases rapidly. Here's an example I wrote about running aggregations:
