State Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode

Dec 12, 2010

I 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",

[Code].....

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.

State Management :: Session Does Not Get Saved If SessionState Mode Is StateServer

Mar 16, 2011

My session variables don't get saved if the SessionState mode in the web.config file is set to StateServer. But when I changed it to InProc, then everything is fine and good. I'm trying to save a custom built object (or class) into the session after the user logs in.

State Management :: Switching From InProc To StateServer Mode?

Jan 18, 2011

I 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?

C# - Unable To Share Session State Between 2 Web Apps With StateServer?

Jul 20, 2010

I'm having trouble getting 2 identical ASP.NET MVC applications to share the same Session using a Session StateServer. The reason I'm trying to do this is we will eventually be deploying this app across 3 web servers that need to share the same state. We need to use StateServer because we are trying to minimise use of the db for non data-related storage.

The Setup: I've deployed the same code base to http://localhost/App1 and http://localhost/App2

both have identical Web.Config files with the following:

<system.web>
<sessionState mode="StateServer"
cookieless="false" [code]....

The Result:For both deployments, when the page first loads I can see that the mode is StateServer and the timestamp is getting set to the same time as the realtime value.. However, if this was working, only the first page should have the same time as the realtime value. The second page load should read from the StateServer because that timestamp value is no longer null, and display that time value. But instead, it's displaying the realtime value again.

When I refresh the page, I the timestamp stays the same and the realtime value is always updating. This indicates that the timestamp is being saved to the Session, but the time stamp value is always different for both deployments when it should be the same, so this indicates that the Session is not being shared.

State Management :: Session Mode State Server - Sending Asynchronous Request

Nov 5, 2010

Customer 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);
}
}

Unable To Serialize Session State - Server Errors

Oct 14, 2010

We have been receiving reports of the following server error periodically from users.
[OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.]
[HttpException (0x80004005): Unable to serialize the session state.]
Please note that non-serializable objects or MarshalByRef objects are not permitted when session state mode is "StateServer" or "SQLServer".

Once in a state where this error appears, it appears to be hit or miss whether the errors are reproducible locally. If they are, then we can usually reproduce them for a couple minutes, but not on every page hit. This usually tapers off on its own and usually has resolved itself by the time we get back in contact with the users. The Web Service has around 90-100 active connections during business hours. The only other site on this server is the staging version of this site, which gets hit very infrequently. The Session State is stored on the same SQLServer instance as the application database which is housed on a fairly large cluster of virtual machines.

Neither the Web Server or the SQLServer seemed to be taxed (either processor or memory-wise) while this is going on. The distribution of which pages are erroring seems to be comparable to the normal distribution for each page. There doesn't appear to be any pattern in terms of times of occurrence. We do have less errors on average on weekends (which correlates to normal site load), but even this appears to not be consistent. There also doesn't appear to be a correlation between the errors logged and any kind of logged performance monitor events. This includes an array of perfmon counters including:

.NET CLR Jit(w3wp)
otal # of IL Bytes Jitted
.NET CLR Jit(w3wp)IL Bytes Jitted / sec

The only pattern I can see in the logs doesn't correlate to the occurrence of these errors, but is the only pattern I can see. Looking at the perfmon logs we are seeing a pattern where the "Total # of IL Bytes Jitted", "IL Bytes Jitted / sec", "% Time in Jit", "# of Methods Jitted", and "# of IL Bytes Jitted" counters for the staging site (which shouldn't be getting any traffic) doesn't pull data for a 20-50 minute period after which there is an immediate spike in "IL Bytes Jitted / sec" and a jump in "% Time in Jit" for 2-20 minute of up to 99% for the main site.

State Management :: Serialize/Deserialize A Custom Class In And Out Of A Session

Mar 18, 2011

I'm trying to save a custom class in a session, but it just never gets saved, along with other sessions. Note that my SessionMode = STATESERVER, and i cannot change it to INPROC as per our business requirement. This is my class

/*******START*******/
[Serializable]
public class User : ISerializable
{
private int _userId;
public int UserId
{
get { return _userId; }
set { _userId = value; }
}
//custom class
private TDB.tdbUser _tdbUserDetails;
public TDB.tdbUser tdbUserDetails
{
get { return _tdbUserDetails; }
set { _tdbUserDetails = value; }
}
//collection of custom class Sites
private List<Sites> _assignedSites;
public List<Sites> AssignedSites
{
get { return _assignedSites; }
set { _assignedSites = value; }
}
public User()
{
//Constructor code
}
/******SERIALIZATION*****/
protected User(SerializationInfo info, StreamingContext context)
{
this._userId = (int)info.GetValue("_userId", typeof(int));
this._assignedSites = (List<Sites>)info.GetValue("_assignedSites", typeof(List<Sites>));
this._tdbUserDetails = (TDB.tdbUser)info.GetValue("_tdbUserDetails", typeof(TDB.tdbUser));
}
[SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("_userId", this._userId);
info.AddValue("_assignedSites", this._assignedSites);
info.AddValue("_tdbUserDetails", this._tdbUserDetails);
}
}
/*******END*******/

The calling code is just this: (User)HttpContext.Current.Session["TDBUSER"];

State Management :: Application State And Session State?

User Interface: 2 Labels; 1 Buttons

Requirements: Create a Web Page in ASPx that will do the following:

1)One label will provide a count of how many times Button 1 has been clicked in the current session.

2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.
