In the ASP.NET MVC site that I'm writing, I'm building a generic Error Action that is routed to by an HttpModule, following this tutorial. In this Action, I will return a View corresponding to the status code that is applied to the response inside the HttpModule (after doing this, the module transfers the request over to the Action in qu...
Hi All- I defined a second level cache in my application using @Cache annotation I am using findById query, as the following: long id = 4; Company cmp = companyDAO.findById(id); Where Company is the object that I get from the DB.

I've got an application that does few computational CPU work, but mostly memory accesses (allocating objects and moving them around, there's few numeric or arithmetic code). How can I measure the share of the time that am I spending in memory access latencies (due to cache misses), with the CPU being idle? I should note that the app is...

I have compared the performance of system.runtime.caching in .NET 4.0 and the Enterprise Library Caching Block and to my surprise it performs terribly in comparison when fetching large data collections from cache items. Enterprise Library fetches 100 objects in about 0,15ms, 10000 objects in about 0,25ms. This is fast, and natural for a...
Hi So I'm making a plugin that gets a set of posts (using wp_query), and it does this every time you refresh a page. Can I cache the query results so the page gets generated faster? If so, how do I do it? because WP_cache functions don't work even if I enable cache in the config file. A alternative to wp_cache seem to be transients. ...
A month ago I adjusted my database schema. I added a column called ordinal. I rebuilt my model and uploaded my changes. Everything works fine apart from my instance of sfLucene will not rebuild. I run symfony lucene-rebuild frontend But I get the error once it gets to the Model in question (others are fine): propel exception: unk...
I'm not talking about binary size. I'm talking about the amount of data that can be written to disk during execution inside of certain directories such as Cache or Documents. I can't find an easy answer in the XCode documentation, which is to say I can find none at all. I know there is a limit for the cache directory in the form of "oh...
Hy there. I need to implement cache for my PHP web application. I implemented the cache file control (saving and getting files from cache dir) but now I need to enforce cache folder max size control, because cache folder should be limited in max size. I had an idea to limit the size by deleting the least used files when the space is nee...
Hi, I am adding a file to distributed cache of Hadoop using Configuration cng=new Configuration(); JobConf conf = new JobConf(cng, Driver.class); DistributedCache.addCacheFile(new Path("DCache/Orders.txt").toUri(), cng); where DCache/Orders.txt is the file in HDFS. When I try to retrieve this file from the cache in c...
hi all, i am looking out for implementing a timestamp based cache with multiple keys. What data structure other than hash tables i would use. Any suggestions... for two values, pair could be used, java (un)fortunately doesn't have a pair. if it has to be triplet or quartet, what architecture is advised. or just the best-practise data ...
I have a page where I am pulling a dataset from the database, a few thousand records. I get it when the page is loaded and store it in the cache. Each time an operation is performed on the page, I check the cache to see if its still there, and if not, go get it again (20 minute expiration); fairly typical setup. When I run the page, the...

I'm using mod_mem_cache in my apache web server to cache static content, but I need to know how to clear the cache. For disk cache I guess you can just erase the directory or use htcacheclean? But I'm not sure what to do for memory cache (without restarting) ...
I have written a small ASHX handler that uses a small state object that I'd like to persist through the lifetime of a series of requests. I have the handler putting the object in the server-side cache (HttpContext.Current.Cache) and retrieving it at the start of ProcessRequest. How long can I expect that object to remain in the cache? ...
I found some code on the web and it threw me off. Look at the code below. You will notice only when the Hits == 1, does the cache get added. After that, the cache object isn't updated. It begs the question, does the object when updated, update the cache as well automatically? The answer here would make me remove some code in some of ...
Env: Seam 2.2.0, JPA, Hibernate 3.3.x, ehcache-core 2.0.1 Here are some observations on using a cache along with Hibernate. We are already using the 2nd level cache but not quite comfortable with the response times. The third option mentioned in the above reference (Direct access to EHCache, only use Hibernate on a cache miss: 20 secon...

I have created a struct to hold the data in memory which can be used as cache so as to avoid reading file every time whenever API is call...
