View 5 RepliesState Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode
Dec 12, 2010I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I checked the stack trace and its complaining about
[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",

I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.

View 2 RepliesState Management :: Switching From InProc To StateServer Mode?
Jan 18, 2011I have an asp.net site that's basically a giant form for users to submit weekly turkey information for their starter and finisher houses. I use session variables so the information is viewable to a "Review" page. There have been 3 instances where the users would try to submit their information but kept losing their information. As far as I know, they are not letting the page sit idle for more than 20 minutes. I tested it out myself and lost session variables after less than 10 minutes. My sessionState mode is InProc. Should I look into switching to StateServer? If so, how would I do this?

View 1 RepliesC# - Best Fix An InProc Session State Variable - Multi Instance?
Oct 21, 2010I've recently been tasked with fixing a rather nasty bug resulting from the misuse of session state. We have an asp.net web application that runs on a single sever using inproc session state. The basic design is that a typed dataset is loaded from the database and stored in session state using a common session variable name like Session["dataset"] = dataset. After the data is stored in the session the user edits the data, dataset is retrieved from the session updated and sent to the database for updating. This type of data editingstoring is used across multiple webforms that basically do the same thing. All is good until a user tries to launch a second instance of the application and data stored within the session variable can get mixed up. Here are the possible fixes that I've been able to find
Set sessionState cookieless="false" (every new instance gets a unique session id) PROS - easiest solution, almost no code changes needed CONS - guid in url, user can edit guid, guid can be copied Use a custom session key for every instance (pass a session key around and combine it the "dataset" + session key name so that each instance has a unique session variable) PROS - no guid in url CONS - most amount of code changes, possibly fragile Remove the session variable (Load the dataset from the database a second time for editing) PROS- frees up server resources, no longer dependent upon session state CONS - performance hit, high amount of code changes

View 2 RepliesState Management :: Session Mode State Server - Sending Asynchronous Request
Nov 5, 2010Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}
}

Session State - Manage Session With Custom Mode?
Jan 3, 2010I am working on a website and this is my first web project. Scenario for Session I have created a database for my project with security level little bit high. I want to manage session for each and every user who is logging in to my website. Session state can be used using Cookie as well as URL, only one at a time. Now I went over with all four session state modes. i.e 1. InProc 2. State Server 3. Sql Server 4. Custom
Now after reviewing from all these modes I am in confusion which one should I use Sql Server or Custom. Basically i want to store session related information in my own database instead of Aspnet_db which is a default database provided by microsoft. I have created all tables related to login and registration. But I dont know how to store session into my database. What tables do I need to create so as to maintain into database. I want to create a complete log of session and login related information into my database(Persistant atleast for 1 year). I want to use machinekey as AES and SHA1.
<sessionState mode="Custom" cookieless="AutoDetect" timeout="15" regenerateExpiredSessionId="true" stateNetworkTimeout="10" >
</sessionState>
<machineKey decryption="AES"
validation="SHA1"
decryptionKey="7E047D50A7E430181CCAF7E0D1771330D15D8A58AEDB8A1158F97EEF59BEB45D"
validationKey="68B439A210151231F3DBB3F3985E220CFEFC0662196B301B84105807E3AD27B6475DFC8BB546EC69421F38C1204ACFF7914188B5003C1DCF3E903E01A03C8578"/>
<add name="conString" connectionString="Data Source=192.168.1.5; Initial Catalog=dbName; Integrated Security=True;" providerName="System.Data.SqlClient" />
What all things do i need to specify in webconfig? My Data Source= 192.168.1.5 Database name= db.mdf What I need to know about. What tables do i need to add to my database to store session related information. eg. Session id (Any other field is also stored or not), Session Time, Session Start Time, Session End Time, Session Expire Time. I dont know what all things are usually taken. Do I need to encrypt Session Id
before storing into database. If Yes Encryption will be automatic or do i need to write some code to do this other than that I wrote in web config above. How mode='custom' will be used into web config using my database. in following code
<sessionState mode="Custom" cookieless="AutoDetect" timeout="15" regenerateExpiredSessionId="true" stateNetworkTimeout="10" >
</sessionState>
IIS InProc Session Variables Randomly Not Written To Session
Nov 12, 2010There are reams of info out there about things causing InProc session to drop session objects, but that's not what's happening here. We're missing individual variables within stable InProc session objects, and are not sure whether they're not being written or being lost after a successful write. I've confirmed with WinDBG that the sessions are live and contain some, but not all, of the data written to them.
Guid g = System.Guid.NewGuid();
this.Context.Session.Add(g.ToString(), result.ImageData);
output.Write("<img src="display.aspx?id=" + g.ToString() + "">");
This code is pretty straightforward, and it works flawlessly in Test. In Production, under heavy load, though, it fails ~1% of the time. If Mr Smith visits the site and attempts to display 4 pieces of image data, 2 of them might be saved in his session and two of them be lost. The InProc session object for Mr. Smith exists. The traffic logs show he clicked 4 times, each with a different id param. But there are only 2 guids in his InProc session object, instead of 4. The 2 session objects we did capture do correspond to 2 of the id's shown in the traffic log (his 1st and 3rd clicks.) The traffic logs for his 2nd and 4th clicks, though, show a guid id that's not in his InProc session object.
Lines 1&3 of the above code obviously worked for those 2nd and 4th clicks, or he'd not have had the id in the URI for him to click. Line 2, however seems to have failed silently in some way. If any exception had been thrown, I'd expect we'd not ever have arrived at line 3. I can't see any way for the user to receive the guid id, but the session to fail to have it. The other possibility is line 2 worked successfully, but the variable later disappeared, how I cannot even imagine.

ASP.NET v3.5
IIS 6

We're running a web farm, but users constantly return to the same server. I'm researching now whether there's any way users might be slipping off to the other server.

View 1 RepliesSession State Sql Server Mode - Retrieve Store Values From Database
Mar 23, 2011My problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
<sessionState mode="SQLServer" allowCustomSqlDatabase="true" cookieless="false" timeout="120" sqlCommandTimeout="30" compressionEnabled="true"
