  • p410i Mirror failed couldnt find same disk

    - by Heishiro Mitsurugi
    I have an HP server with an P410i RAID Card installed. I had two SATA Drives connected (250GB each). The RAID was configured as a Mirror. A few days ago the drive one (1) failed, and i had to remove it. Tried to find the same part number here in Venezuela, but i couldn't. So, i bought a 500GB SATA Drive, and connected it to the same bay where the 250GB failed drive was. When the server booted, it asked me if i wanted to rebuild the data. I selected the option for that, and Windows Server restarted properly. When i got into the ACU (Array Configuration Utility) it told me that it was rebuilding the data. Today the warning went away, and according to the ACU everything is just fine. My question is... What i did was right? Can i create a mirror from a 250GB disk in a 500GB disk using the p410i? I have done that before, but only using software RAID in Windows, and it just uses the space it needs. As a matter of fact, when did that using Windows i was able to use the remaining space in the bigger drive, but in the p410i i can't use it. Should i be worried? Thanks a lot in advance for any pointers or info that you could give on this. Heishiro

  • Performance of external USB disk with ESXi5

    - by PeterMmm
    I have a new HP DL120 G7 server with ESXi5. One VM is a Win2003 instalation and I have an external USB2.0 drive attached by USB Controller and USB Device. I copy a 4GB file from external USB to server disk. In the VM that takes up to 10 minutes. On a native Win2003 that takes aprox. 3 minutes. I have no explaination for that diference: In any case the bottleneck is the USB connection, much slower than the disks (SAS, RAID1). If the USB connection on the VM would be USB1.1 and not USB2.0 it would take much more time. (The disk performance between server partitions on the VM is correct. - see update) Could be that my native box is extremely fast and the VM is the normal case. ??? Update I try with passtrough and a first run copy the same data in aprox. 7 minutes. Still 2 times slower than the native connection. I also did another messure and the copy between partitions on the same VM takes 3 minutes.

  • ASP.NET MVC 2 disable cache for browser back button in partial views

    - by brainnovative
    I am using Html.RenderAction<CartController>(c => c.Show()); on my master Page to display the cart for all pages. The problem is when I add an item to the cart and then hit the browser back button. It shows the old cart (from Cache) until I hit the refresh button or navigate to another page. I've tried this and it works perfectly but it disables the Cache globally for the whole page an for all pages in my site (since this Action method is used on the master page). I need to enable cache for several other partial views (action methods) for performance reasons. I wouldn't like to use client side script with AJAX to refresh the cart (and login view) on page load - but that's the only solution I can think of right now. Does anyone know better?

  • Sync Framework, Local Database Cache, and my DAL

    - by Refracted Paladin
    I am creating a WPF app that needs to allow users to work in a temporary disconnected state and I plan to use a Local Database Cache. My question's are about my data access layer. Do you typically create the whole DAL to point at the Cache or both and create a switching mechanism? Is Entity's a good way to go for my DAL against the Cache? I am used to L2S but my understanding is that I can't use that against SQLCE, correct? Thanks! PS: Any good resources out there for using Sync, Linq, and WPF? Tutorials, videos, etc?

  • Can you clear jquery ajax cache?

    - by chobo2
    Hi I am wondering is it possible to clear the cache from a particular ajax method? Say if I have this $.ajax({ url: "test.html", cache: true, success: function(html){ $("#results").append(html); } }); Now 99% of the time a cached result can be used since it should always be same content. However if a user updates this content it of course changes. If it is cached and it would still show the old content. So it would be cool if I could pick out this cache for this method and clear it and all other cached stuff would stay. Can this be done?

  • Grails / GORM, read-only cache and transient fields

    - by Stephen Swensen
    Suppose I have the following Domain object mapping to a legacy table, utilizing read-only second-level cache, and having a transient field: class DomainObject { static def transients = ['userId'] Long id Long userId static mapping = { cache usage: 'read-only' table 'SOME_TABLE' } } I have a problem, references to DomainObject instances seem to be shared due to the caching, and thus transient fields are writing over each other. For example, def r1 = DomainObject.get(1) r1.userId = 22 def r2 = DomainObject.get(1) r2.userId = 34 assert r1.userId == 34 That is, r1 and r2 are references to the same instance. This is undesirable, I would like to cache the table data without sharing references. Any ideas?

  • Disk-based caching of dynamic images in IIS 7

    - by Daniel Schierbeck
    I'm writing an image server which needs to handle a relatively large number of concurrent requests (~5,000). The images being served are dynamically scaled down and cropped based on per-image specifications, which are queried from a database. The number of images is rather large, so an in-memory cache isn't viable (thrashing would most definitely occur). I'm using native caching in IIS 7 to avoid hitting the ASP.NET app which generates the images on-the-fly. I've looked around, but I couldn't find a simple way to configure IIS to store the cache on-disk -- is there such an option, or would I need to roll my own? I'd rather avoid placing the generated images in a public folder, so they can be served statically, since I would prefer to invalidate the cache entries using a query parameter (last-edit time from the database,) which doesn't seem possible to reconcile with static caching. I would love to get some feedback on this!

  • rails expiring cache

    - by ash34
    Hi, I entered some products data into a table using a migration. I need to expire the page and fragment cache when I update, add, delete products from this table. I created a sweeper for this. class ProductSweeper < ActionController::Caching::Sweeper observe Product def after_create expire_cache end def after_save expire_cache end def after_update expire_cache end def after_destroy expire_cache end private def expire_cache expire_page(:controller => 'ProductsController', :action => 'index') expire_fragment 'listed_products' end end Then in script/console I update the product name and saved. When I reload my app in the browser it still gives me a cache hit. Cached fragment hit: views/listed_products (0.2ms) Can someone tell me how to expire this cache. I will not be adding, updating, deleting products through a controller action. thanks, ash

  • Magento cache wrong read permissions?

    - by Lucasmus
    There seems to be a problem in Magento's reading of the var/cache directory. I've disabled Full Page Caching for testing. When I execute the bash command chmod -R 777var/cache/` before loading the page, it loads ~3 seconds quicker (the time it takes before 'mage::dispatch::routers_match' is reached in the Profiler is reduced from ~4 seconds to ~1 second). This speed-up remains a while but then is lost until the chmod is called again. I'm guessing this has to do with writing permissions somehow? The odd thing is, the cache contents are afaik owned by the process that is executing magento (the web user). Does anyone have any clues what could be the problem or what could be changed to prevent this?

  • Does this simple cache class need thread synchronization?

    - by DayOne
    Does this simple cache class need thread synchronization ... if I remove the lock _syncLock statement will encounter any problems? I think i can remove the locks as the references should be updated correctly right? ... BUt i'm think whar happens if client code is iterating over the GetMyDataStructure method and it get replaced? Thanks! public sealed class Cache { private readonly object _syncLock = new object(); private IDictionary<int, MyDataStructure> _cache; public Cache() { Refresh(); } public void Refresh() { lock (_syncLock) { _cache = DAL.GetMyDataStructure(); } } public IDictionary<int, MyDataStructure> **GetMyDataStructure**() { lock (_syncLock) { return _cache; } } }

  • cache problem in asp.net

    - by JoelFan
    I'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting <clientCache cacheControlMode="DisableCache" /> in the relevant <location> tag in web.config If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?

  • Save NSCache Contents to Disk

    - by Cory Imdieke
    I'm writing an app that needs to keep an in-memory cache of a bunch of objects, but that doesn't get out of hand so I'm planning on using NSCache to store it all. Looks like it will take care of purging and such for me, which is fantastic. I'd also like to persist the cache between launches, so I need to write the cache data to disk. Is there an easy way to save the NSCache contents to a plist or something? Are there perhaps better ways to accomplish this using something other than NSCache? This app will be on the iPhone, so I'll need only classes that are available in iOS 4+ and not just OS X. Thanks!

  • Automatically clear cache of all major browsers installed

    - by MorganTiley
    I would like a way to clear cache from all my locally installed browsers - quickly and easily. A simple utility that would ask "Clear all browser caches?" with Yes/No. Just the major browsers -IE, Firefox, Safari, Chrome and optionally Opera I understand CCleaner can do this but it is not as simple as I would like (as it has other functions as well). I tried googling/stacking and couldn't find anything.

  • DNS queries to compromise DNS cache [on hold]

    - by Chris
    The transaction ID for DNS queries can take values from 1 to 65,536 and my computer pseudorandomly chooses one for each DNS request. If I sents 1,024 false replies per request, how many requests should I trigger to compromise the DNS cache with probability 99%? or as close tot hat as I can get. Thanks I'm getting a result of .6 requests which doesn't seem right to me. Feel as though it should be around 30

  • Remove deleted posts from central google reader cache

    - by bogdanbrudiu
    After posting some test blog entries, I then remove them from my blog. however, once loaded by google reader, they never disappear from it. Even if I sign up to my blog feed from a different account, they still appear, so it seems that they are centrally cached by google reader. How can I force google reader to delete them from cache?

  • Header precendence: Apache Vs. PHP specific to cache-control & expires

    - by David
    My companies production dynamic web servers ( Apache + PHP 5.1x) are using the Apache expires module and there is a clause inside http.conf as follows: <FilesMatch ".+"> ExpiresActive On ExpiresDefault "A0" </FilesMatch> If I were to set inside a php script "Cache-Control" and "Expires", would it get eaten by this clause? Normally I would test this on my own but having trouble convincing the Expires module to function on my workstation and the company Admin's are down at the data-center.

  • NGINX Cache Viewstate and Cookies

    - by user42833
    We are running NGINX 7.65 on a Ubuntu 10 server. NGINX is setup as a reverse proxy to an IIS website where the viewstate is passed through the headers. We want to set up the cache feature in NGINX but need to make sure it does not mess up the viewstate and cookies associated with each individual customer. Will adding this to the nginx.conf file fix this - proxy_pass_header Header or is there more that would need to be done? Thanks,
