State Management :: Save Session Data To Oracle 10g R 2 In Application?

Feb 26, 2011

I am creating a web application that will be running on an infrastructure which will utilise a number of web servers, web gardens and a load balancer.

As the application is using Sessions, and that our application is using Oracle as the database, we would like to use the database to save the Session data. However, I am struggling to find any good examples on how to do this with Oracle.

I note that Oracle provides the following class: Oracle.Web.SessionState.OracleSessionStateStore, but I am unsure what I need to do in the Code Behind and what if any tables do I need to create in the database.

State Management :: Session State Expiration After Application Pool Recycle?

Nov 1, 2010

All we have a global ships position tracking website which runs smoothly until IIS application pool recycles.When there is workerprocess recycling looks like session state expires as a result i loose all session data and when customer clicks refresh button he is redirected to login page.

In web.config Session state mode is set to InProc so i changed it to State Server but to my luck i have MAP object which is not serialiazable which is causing the maps from not appearing on the website.I tried adding serializable attribute to the object class but still not succesfull.Our website is accessed by our customers whose count is more than 1000.

Changing the session state mode from InProc to StateServer can really slow down the response time so
Is it good to go further fix the serailizable issues and move to state server?.

Is there any way I can retain my session data when application pool recyles?..

Stopping Application pool from recycling may not be a good idea considering health factor of web server.

State Management :: Application State And Session State?

Oct 2, 2010

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.


Partial Class _Default
Inherits System.Web.UI.Page
Dim clickcount As Integer

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Session("ClickCount") Is Nothing Then
clickcount = 0
clickcount = CInt(Session("ClickCount"))
End If
If Not IsPostBack Then
If Request.Cookies("UserName") IsNot Nothing Then
Label1.Text = "Welcome Back " & Request.Cookies("UserName").Value & "."
End If
End If
Dim clickCounta As Integer = CInt(Application("ClickCount"))

State Management :: Session Suddenly Times Out On One Application?

Aug 10, 2010

I have a web application that was working fine. I had to make minor changes that had nothing to do with the Session object in any way. When I run local everything works fine. When I publish to our testing box it all runs fine. When I publish to production it times out on the Session object. Dozens of other applications on the production server run fine and have no trouble with Session.

It does not matter if the line is:

Session("PreferredName") = sPreferredName
sPreferredName = Session("PreferredName")

I had the server admin remove the application pool and directory and recreate them and then I republished and it still happens.

State Management :: Session And Application Cache Items Disappear?

Mar 31, 2010

i've been coding an site using VS2005 for about one month.

my site uses both application cache and session cache to save data.

the syntax i use for application cache is :

HttpApplicationState appState = Application;
appState["someKey"] = "somevalue";

and for session cache i use :

HttpContext.Current.Session["someKey"] = "Somevalue";

my site is deployed on three standalone servers - each server runs a diffrent instance of the site.

two of the servers work just fine, the third has a stange problem - and also has the least free memory space.

in this server items start dissapearing from both the session and application cache - note that i set no expiration date to the cache items.

does anyone know why this could happen?

seems to me there is perhaps some memory limit for cached items setting that i am missing.

State Management :: Session Variable And Multiple Web Application Instance

Oct 13, 2010

I have a web application using window authentication. There are a search page and a edit page in the application. In search page, user can enter some search criterias in the textboxes and the search result will be displayed in the gridview by clicking the "Search" button. User can select any row from the gridview and it will take him to the edit page. In the edit page, there is a "Back" button to take the user back to the search page. I use session variables to remember what the search criterias the user entered in the textboxes and what page number the user was in the gridview. So when the user goes back to the search page, the textboxes are pre-populated with the search criterias and the gridview is displayed in the correct page number.

The problem is: If user1 opened one browser window and did a search using search criterias1, then user1 opened a 2nd browser window and did a search using search criterias2. When the user1 went back to the search page from the edit page using the first browser window, all the textboxes and page numbers are from the 2nd browser window, instead of the 1st one. Can anyone explain this problem to me and how to prevent it? It will be helpful too if you can give me some links about the similar problem. I am thinking if the same user logged on two different machines and did the search on each machine, what is the result?

State Management :: Storing Large Data In Session State?

Sep 18, 2010

We have a scenario where we need to store large tables of data on Session in page. on a highlevel we have to store following data

1> A table (table 1) with 1000 rows and 8 to 10 columns.

2> A table(table 2) with 500 rows and 8 to 10 columns (actually user can add the data from table 1 to table 2, so as user keeps on adding from table 1 we remove the data and put it in table 2)

3> Another table(table 3) with 1000-1200 rows each having 3 columns.

We are having a webfarm, so we need to store it in either SateServer of Oracle DB,What would be the performance implications of storing such huge data on the server.

One more thing is at any point of time max of 70 -80 people will be accessing our website, so will this cause any performance degradation?

State Management :: How To Save Intermediate Data

Jun 10, 2010

I have a scenario where intially I make 1 trip to database and get all the data required

At first page load I display only some of the data (it is more like Collapse and Expand feature on Reports)

Now as and when required users Expands and Collapse Rows

Depending on the requirements I query the orignal data set and display the records

What is the best method to store these larger chunk of data aw well as the in between state of the displayed table

Till this point I was storing the dataset in session variables

One way I thought was retreiving the data from Database and then store it in XML file along with UserId and current time

Then for the modified table another file which gets updated as and when the request change

I am not sure if Caching is going to work since every user will request different data

State Management :: Session Became Null - Maintain Data?

Aug 17, 2010

I have a requirement where i need to download mutiple files as a single zip file.There is linkbutton named HOME as well in the page. when this linkbutton is clicked it should redirect to homepage.aspx. I found a ICSharpCode.SharpZipLib.dll in net and used in my website. Here is the code


With the above code i got the expected result i,e. i can zip the files and save on client system. But the problem is after saving/canceling the zip file if user clicks on linkbutton in the page_load event Session[getdata] became null. there is no data in Session. what might be the problem? Actually it should redirect to homepage.aspx but its going to login.aspx because Session[getdata] is null.

State Management :: Losing Session Data With Response.Redirect?

Oct 25, 2010

This is weird. In my newly developed chat application, when I invoke Response.Redirect, I am losing my session data. What is particualrly odd is that this sometimes seems to occur after a slight delay, so I reach the page, and then the session info gets lost momentarily thereafter. Mostly though it seems to get lost immediately. I have of course googled this issue, but yet to find anything that speaks to my problem. SessionState is in InProc mode. Session state has been working fine for me until this unexpected problem, so everything is configured right. So far the only workaround I can think of is to use a link instead of a button, and use javascript to call a server-side function on onclick to do the work I need to do before the link gets invoked. Messy, and I'd rather not go that way unless there's no alternative.

Just to preempt one red herring, I do use Response.Redirect(<address>, false).

The problem occurs both on the testing and production servers. I'm running ASP.NET 3.5 on IIS7.

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.

function SendRequest(msg, isBusy, chartMsg, vesselMsg)
_busy = isBusy;
if(chartMsg != null)
_element.SetMessage(true, chartMsg);
if(vesselMsg != null)
_element.ShowVesselLoading(true, vesselMsg);
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
alert( "Exception error on SendRequest(): " + e);

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",


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.
