C# - Find Out How Much Memory Is Currently Consumed By Cache

Nov 8, 2010

I'd like to modify the value of my Sliding Expiration time span based on how much memory is available. If the site's traffic is high at any point in time, more data will be added to the cache than during quieter periods. During those quiet periods I can increase the sliding expiration time span, thus allowing data to be stored longer. But when the site is busy I need to free up memory so I'm happier with a shorter time span.

So I guess my questions are as follows: Is it possible for me to find out how much memory is being consumed by the items I've added to HttpRuntime.Cache? If so, how? Does this sound like a realistic solution to the problem I've described?

Architecture :: Cache The Full List Of Objects In Http Cache On The Service Tier And Page In Memory?

Feb 25, 2011

We have a wfc layer that wraps the business classes and database access and use a client that lives on the database layer. Amongst our group we are attempting to form standards. Some want to have the client call the web method and pass the page they are requesting and the page size. Pass that to the database and then page in SQL Server use RowNum.Some want to cache the full list of objects in http cache on the service tier and page in memory. They concern here is memory use on the server.

Which would be best for a medium number of users with potentially large number of records to manage (say 30K) Is it better to cache them all in memory and work from there or page at the database as the application scales?

Caching - Controlling Output Cache Memory Usage?

May 17, 2010

I would like to use output caching with WCF Data Services and although there's nothing specifically built in to support caching, there is an OnStartProcessingRequest method that allows me to hook in and set the cacheability of the request using normal ASP.NET mechanisms.

But I am worried about the worker process getting recycled due to excessive memory consumption if large responses are cached. Is there a way to specify an upper limit for the ASP.NET output cache so that if this limit is exceeded, items in the cache will be discarded?

I've seen the caching configuration settings but I get the impression from the documentation that this is for explicit caching via the Cache object since there is a separate outputCacheSettings which has no memory-related attributes.

Here's a code snippet from Scott Hanselman's post that shows how I'm setting the cacheability of the request.

State Management :: Deleting Data In Cache Memory?

Mar 4, 2011

I have a webpage which displays some data along with a banner. The banner image is stored in the database with parameters "Pagename" and "form".

The application has been coded in such a way that when the page loads , a function checks for the banner in cache memory first with the parameters "pagename" and "form". It the banner does not exist, the new banner is retrieved from the database and is added to the cache memory. Next time when the same page is called, the banner is displayed from the cache memory avoiding the DB to be hit everything to get the banner.

Now, I do not want a specific banner to be displayed on the page. I have removed that banner from the DB but the banner still gets displayed as this banner is still there in the cache memory.

Is there any way to delete the banner which exists in cache memory without making any code changes?

Error Occurring When Using Wcf To Run Query - Memory Gates Checking Failed Because Of The Free Memory

May 21, 2010

I am building an asp.net application, using II6 on windows server 2003 (vps hosting).

I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).

When my wcf service tries launching my query running against a local sql server this is the error I receive:

Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.

Error: Attempted To Read Or Write Protected Memory. This Is Often An Indication That Other Memory Is Corrupt?

Oct 11, 2010

I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.

Attempted To Read Or Write Protected Memory. This Is Often An Indication That Other Memory?

Jan 26, 2011

I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.

(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)

My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?

Securing Web Services To Be Consumed From Flash?

Oct 18, 2010

my team is building a game in flash to be embeded in a asp.net application.

When the game is over the player have the chance to type his name to save his score. This is done using web services called from flash. The webservice receives the name and score.

Since the webservice is publicly available how can I make it only callable from my flash given the following conditions:

The .swf is hosted by the same asp.net application There are two domains that can access the same application (I have run previously into cross domain issues). Using SSL is not an option. The webservice has to be consumed by the .swf file.

WCF / ASMX :: Write A Webservice To Be Consumed By An Application?

Sep 20, 2010

I need to write a webservice to be consumed by an application. The application will read the WSDL and provide me with the input output fields that I can utilise. The webservice output should be an array of string values as the output. I have taken a dataset and can output that as XML but I need to provide a description in WSDL what the output format will be and I cannot seems to get my head around to that. What I need is something similar to[URL] but do not how to write the WSDL to give me a clear input and output structure in the definition.

DataSource Controls :: Memory Leak - Server Will Crash - Log A Ton Of SQL Errors Stating That It Is "out Of Memory"

Jul 27, 2010

I have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".

I cant find it anywhere, all of my connections are being disposed like so:

[Code]....
Then I call the connection from my pages like so:[Code]....

That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....

Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....

So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?

ANTS Memory Profiler - Which Memory Should Be Looking At?

WCF / ASMX :: Default Values Specified To Class, Does Not Persist When Consumed From Webservice

Jul 29, 2010

I have web service with reference of BO library in same application. My BO contains classes with some private members and respective public properties.

All of these private members had default values in a perticular class say Contact.cs.Now when I consume this webservice into Windows Application, these already assinged values to BO does not persists in the Windows Application code.

Is there any limitation such that you can serialize the default values assosiated with private members ?

Even I have tried to assign these values directly to the properties in a constructor of Contact class.

Web Forms :: Event Fire In User Control - Consumed By Parent Page

May 13, 2010

I have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:

<asp1:Object id="objectMain" runat="server" OnClick="Click" />

Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?

New-Cache Parameters For AppFabric Cache When Storing.NET Session State

Jul 28, 2010

What are the "optimal" parameters for creating an AppFabric cache when you will be storing session state in the cache? MSDN Cache-Related Commands

Powershell command line:

New-Cache [-CacheName] <String> [-Eviction <String>] [-Expirable <String>] [-Force [<SwitchParameter>]] [-NotificationsEnabled <String>] [-Secondaries <Int32>] [-TimeToLive <Int64>]

[code]...

Since I don't want my sessions to be removed unless the session has been abandoned either via code or Session Timeout...For eviction, I would think "None" and for expireable, I would think False.I have tested and calling Session.Abandon does remove the object from the cache. I have also tested to see if by extending my session, the session object in cache is also extended. This does seem to work the "correct" way.

Data Cache Support Background Population Of Cache Entries?

Aug 1, 2010

We have a data driven ASP.NET website which has been written using the standard pattern for data caching (adapted here from MSDN):

public DataTable GetData()
{
string key = "DataTable";
object item = Cache[key] as DataTable;

[code]...

The trouble with this is that the call to GetDataFromSQL() is expensive and the use of the site is fairly high. So every five minutes, when the cache drops, the site becomes very 'sticky' while a lot of requests are waiting for the new data to be retrieved.

What we really want to happen is for the old data to remain current while new data is periodically reloaded in the background. (The fact that someone might therefore see data that is six minutes old isn't a big issue - the data isn't that time sensitive). This is something that I can write myself, but it would be useful to know if any alternative caching engines (I know names like Velocity, memcache) support this kind of scenario. Or am I missing some obvious trick with the standard ASP.NET data cache?

C# - Maximum Length Of Cache Keys In HttpRuntime.Cache Object?

Feb 24, 2010

We are using HttpRuntime.Cache API in an ASP.NET to cache data retrieved from a database.

For this particular application, our database queries feature a LOT of parameters, so our cache keys look something like this:

table=table1;param1=somevalue1;param2=somevalue2;param3=somevalue3;param4=somevalue4;param5=somevalue5;param6=somevalue6... etc...

we have so many parameters that the cache key is several hundred characters long. is there a limit to the length of these cache keys? Internally, it is using a dictionary, so theoretically the lookup time should be constant. However, I wonder if we have potential to run into some performance/memory problem.
