I am in the process of writing a simple web server monitor (ASP.Net with
VB.Net). One piece of useful information for me to gather would be the
amount of memory used by objects stored in the cache, since objects are
thrown in there left and right.
Items in the cache are either custom objects or are Hashtables. How can I
get the memory size of these objects.
Marshal.SizeOf(object) does not work in this case because .Net cannot
Marshal Managed objects. I thought that I might be able to pull out the
component items in each object and build the total size from their aggregate
sizes, however that would require me to determine each objects type so that I
can correctly gather size info from the internal attributes, something that I
do not want to do.
Is there a generic way to either:
1) get the size of Managed Objects
2) convert Managed Objects into Unmanaged Objects that can be marshaled?
OR
3) some other way to get memory sizes of cached objects
I have a problem with our web servers and memory etc.
We have one application pool with a few websites in it and the w3wp.exe is consuming about 800 mb memory now. First we had a rule for recycling the application every x minutes or when it's using more than 600 mb memory but when the recycle is activated the w3wc.exe process hangs and the cpu usage goes to 100% until we execute an iisreset.exe.
That's the reason why we disabled all the recycling options and configured only one worker process for that application. All the websites in the application pool use the same code, only they have a different skin. The website also uses xml/xsl transformations.
Is it normal for an application to push the w3wc.exe process to about 1GB??? If this is the case i really want to know how much memory dedicated hosting companies need in their webservers :-)
We are storing some information in the application cache, but this is only for the entire website and not per user... in plain text so the amount of data would be no greater than 100KB at most.
The application is in classic ASP. We walked thru the entire code and checked for correctly closing all sql recordsets, email components etc etc etc...
What is the best approach to find out what is using so much memory and why the recycle does not work correctly?
When using cookies in classic asp, is it safe to assume that using a comma delimited list of values in one cookie is much more efficient than using multiple cookies? (example below)
Response.Cookies("someCookie") = "101,102,103,104,105,106" If InStr(Request.Cookies("someCookie"),"103") 0 Then.......
In ASP, is it absolutely necessary to set an object to Nothing after being used?
set myObj = server.createObject("myDLL.myClass") call myObj.useClass set myObj = Nothing <--- can I omit this?
I'm dealing with a large number of files with nested includes. There are many places where I use the object, I want to avoid initializing the object any more than necessary, and I want to change as few pages as possible. The simplest way for me to do this is to not set the object to nothing. Will ASP implicitly remove the object from memory, or will I have a memory leak?
I deployed a number of managed thin clients running XP Embedded. These thin clients are located thousands of miles away and their management (consider they are very locked-down) is not trivial. I would like to install on each thin client a small web server so that I could connect to each thin client and be able to retrieve certain data such as name, ip address, up time, application version installed, etc.
is there something like this in the market somewhere that I could use or do I have to code it myself ? I tried to install apache and play a bit with it but I'm really not expert using asp or php. I'm rather good at vbscript if that can help. What should I do in order to accomplish this task ?
If I have to code it myself, would it be possible just to get instructions on how to display on a web page a very basic data such as the ip address or the host name of the computer ? This would get me started.
I have a client that wants a web form to send credit card information and other personal information to an email address. (such as name@aol.com) Now I am uncertain on how to do this. I know SSL must be involve, but what is the process with this and how to use it with ASP ? How do you use SSL with ASP .
I am building a small Web app that will allow end users to visit a Web page, click a button which will in turn execute a batch file on the Web server which will migrate code from the development environment to QA. The Web app will also capture logins and execution requests, and the batch file currently emails the robocopy log to me. In researching ways to get the ASP page to execute the batch file, I came across ASPExec from Server Objects - http://www.serverobjects.com/products.htm#free. It seemed straightforward enough, however I have not been able to get the permissions in sync for it to work.
I have just figured out how to use the global.asa file to track sessions on my site. However it relies on users logging off correctly. Is there no way that I can know that the user has closed the browser WITHOUT logging off my site? I am finding users registered as being logged in when they may not be Could anyone show me some code that I could put in Session_OnEnd that would clean up my database table of active users? Say if a user has been in-active for 60 minutes, clean him out. I have tried to do this but it hasn't worked. I cannot seem to connect to my access db from the global.asa file!
i have an access database which iv'e designed for my 'client' (ok, he's my friend) and now i'm also in the process of designing a website for his company - so his customers can log on and see their order status.
what's the best (and most secure) way to update the site - we don't host the site - it's hosted by someone else.
i'm totally at loss with this - since iv'e never worked with networks or servers and i just want someone to point me in the right direction. i don't want to get lock errors and the like.
iv'e heard a bit about ADO and i know some of the syntax although i'm not really sure how it applies to me here (i'm not exactly exposed to ADO since iv'e been learning asp.net 2.0 from which i understand, has totally eliminated ADO)
What difference does it make?I am building a table whose number of rows keep changing When i use the second method the space above my table keeps increasing.I just want to know which method is better..I had posted a similiar question....I'm still trying to figure out.
I'm currently working on a survey system that allowes users take the survey and then review/change their answeres in any order. The system uses 3 frame (Header,Body,Footer).
As it stands the system uses 3 sessions to get this done. One for the project they are in, one for the step they are in and one for their answers.
My question is at what point do I end up over whealming the system with sessions? I truly do not want to slow the system down that much. how I could optimize the usage of this?
Is there a way to use a Session Variable to prevent the successful resubmission of a form if the user uses the Back button and tries to submit it again?
Hi's there any concerns or disadvantages of using alot of respose write's (50) in a ASP page for calculations and is it better than using the recordsets to do the calculations?
Also, we are looking at moving to a secure server, will this cause any problems apart from changing all references to https?
Can anyone point me in the right direction for dealing with a dynamically created table of shopping cart items? Each row (or Item) has a column where the user can change the quantity. Is there an easy way to grab and use these changed values when they hit the form submit button?
Or, do I need to bite the bullet and write code that filters through the form fields named "quantity1," "quantity2," "quantity3," etc... And then determine which one goes with which cart item?
I have 4 ASP pages where an user can update some fields and submit the page, so that the fields are updated in the Database(Sqlserver), I need to handle one situation.
1) At a time I need to allow only one user to update the details in a page.
2) I need to stop other users who are trying to access the same page concurrently(probably with a message or Redirecting to other page where he can see the details in a report format).
3) Session timeout in my application is 60, So if the first user leaves the page open for a long time , I think it would be a problem....the other session has to wait for a long time. I have no choice in decreasing the session timeout interval.
I am trying to get a thorough understanding of a code where a addition or deletion of records can be done from a list of records. For addition part of the form, data is being obtained from set of input boxes. Code:
We are receiving an error in our ASP website that used to run fine on our old servers but seems to be struggling on our new ones, I'm wondering if you've seen this error before?
Microsoft Cursor Engine error '8007000e'
Out of memory.
/oob/activities/default.asp, line 470
The last line that shows where the error happening is different on every page but it appears at the first database connection on each page.
The only way to get rid of the error and get the site working again is to recycle the application pool for the site (or restart IIS).
We have two servers, one running IIS and the other running MSSQL 2005. Both are the following specs: Code:
I think I already know the answer ("NO"), but I figured I'd ask anyway:
Is there a way to populate a SQL-like object entirely in memory, without having to save it in a SQL-like environment like MySQL, MS-SQL, or Access?
I'd like to take the contents of some CSV's and dump them into a virtual SQL table, and then call from that table using a SQL statement ("SELECT * FROM VirtualTable WHERE Foo='Bar'"). I know that in .NET I could use a data-grid to do basically that, but I was wondering if there was a classic ASP solution.
I am getting an ASP error.. that tells the server it is OUT OF MEMORY.then the server displays a message about the DLLHOST.exe and it waits for an "OK" from me.after hitting OK... it goes back to working fine.BUT, while the notification is up on the screen.the website is NOT AVAILABLE.that is the message that visitors get when they try to get to the website.so, is there a way I can tell the system to SKIP the notification .andmjust restart the service.
What memory is the issue here.I am assuming this memory error is coming from an INFINITE LOOP or something.from one of my ASP pages. so, I would imagine the best move would be to get RID of the "On Error Resume Next" code at the top of my pages.. to try and isolate the problem?
I was working with filesystemobject in asp. When i give filesysstemobject.copyfile the system will be gogin searching indefelty and IIS will get crash.. Why this pblm occurs..
I would like to know if someone has already exchange ASP objects by SOAP with the SOAP Toolkit 3.0 ? Is-it possible ?Because, I have to connect, with ASP, to a Web Service and send to him array of objects.
I'm so glad i finally found a web development forum! It's been a while and it's not easy to find. Until someone recommended this site to me.
Enough about that... I really want to learn about COM objects and don't really know where to go to find out about such things.
If someone could direct me to the right place, i'd be extremely grateful.
I've already learned ASP and PHP (though i have to admit that i am not an expert and I don't think i'll ever be one), but i aim to be a "jack of all trades".
I'm having a problem that I can only attribute to something that I don't know about ADO. I am using an ADODB.Connection with .CursorLocation = 3 since I am using MSSQL with text fields.
I am running a large set of 4 LEFT JOINS (5 tables in all). Currently my recordset is returning 168 rows and 23 colums. After looping through the ADO connection 27 times (creating a pdf report for users to print) the data goes nutz. I have tried using different inputs and no matter what on the 27th time is stops.
I am trying to write a search script in my spare time at work. We have a knowledge base consisting of 200+ .mht files. My script was working ok when I was testing it on just a few files but I am getting out of memory errors trying to search through the whole KB. Here is the search code:
am just wondering is there a easier way to release all the memory after the program is done?or do I need to set all my variable = nothing one by one at the end of my code?
We've got this problem on our site where slowly eats virtual memory until IIS stops serving pages...
Restarting the IIS process fixes the problem, until the next time it reaches that point. I've made sure all our ADO objects are being closed and set = Nothing. I don't know what else could eat up all that memory...
