  • Which network protocol to use for lightweight notification of remote apps?

    - by Chris Thornton
    I have this situation.... Client-initiated SOAP 1.1 communication between one server and let's say, tens of thousands of clients. Clients are external, coming in through our firewall, authenticated by certificate, https, etc.. They can be anywhere, and usually have their own firewalls, NAT routers, etc... They're truely external, not just remote corporate offices. They could be in a corporate/campus network, DSL/Cable, even Dialup. Client uses Delphi (2005 + SOAP fixes from 2007), and the server is C#, but from an architecture/design standpoint, that shouldn't matter. Currently, clients push new data to the server and pull new data from the server on 15-minute polling loop. The server currently does not push data - the client hits the "messagecount" method, to see if there is new data to pull. If 0, it sleeps for another 15 min and checks again. We're trying to get that down to 7 seconds. If this were an internal app, with one or just a few dozen clients, we'd write a cilent "listener" soap service, and would push data to it. But since they're external, sit behind their own firewalls, and sometimes private networks behind NAT routers, this is not practical. So we're left with polling on a much quicker loop. 10K clients, each checking their messagecount every 10 seconds, is going to be 1000/sec messages that will mostly just waste bandwidth, server, firewall, and authenticator resources. So I'm trying to design something better than what would amount to a self-inflicted DoS attack. I don't think it's practical to have the server send soap messages to the client (push) as this would require too much configuration at the client end. But I think there are alternatives that I don't know about. Such as: 1) Is there a way for the client to make a request for GetMessageCount() via Soap 1.1, and get the response, and then perhaps, "stay on the line" for perhaps 5-10 minutes to get additional responses in case new data arrives? i.e the server says "0", then a minute later in response to some SQL trigger (the server is C# on Sql Server, btw), knows that this client is still "on the line" and sends the updated message count of "5"? 2) Is there some other protocol that we could use to "ping" the client, using information gathered from their last GetMessageCount() request? 3) I don't even know. I guess I'm looking for some magic protocol where the client can send a GetMessageCount() request, which would include info for "oh by the way, in case the answer changes in the next hour, ping me at this address...". Also, I'm assuming that any of these "keep the line open" schemes would seriously impact the server sizing, as it would need to keep many thousands of connections open, simultaneously. That would likely impact the firewalls too, I think. Is there anything out there like that? Or am I pretty much stuck with polling? TIA, Chris

  • HTML Encoding with ASP.NET

    - by Corin
    I am currently html encoding all user entered text before inserting/updating a db table record. The problem is that on any subsequent updates, the previously encoded string is reencoded. This endless loop is starting to eat up alot of column space in my tables. I am using parameterized queries for all sql statements but am wondering would it be safe to just let the .NET Framework handle this part without the HTML Encoding?

  • how to dynamically break NHibernation cascade

    - by Joe Black
    The NHibernate cascade setting in the entity mapping is static. Is there anyway to dynamically disable the "cascade" setting in code to avoid expensive cascade operation in NHiberate during a bulky data transaction? We do not want to use stored procedures or native SQL because we need to have the entity changes captured by NHibernate (audit).

  • Fluent NHibernate Column Mapping with Reserved Word

    - by Josh Close
    I've read that using a back tick ` should allow for using of reserved words. I'm using SQL Server and Fluent NHibernate and have a column name "File". If I map it with "`File" it tries using [Fil] so it's adding the brackets correctly, but dropping the "e" from the end. If I map it as "`Filee" it uses [File] correctly. Am I doing something wrong or is this a bug in NHibernate or Fluent Nhibernate?

  • How to store a scaleable sized extensible event log?

    - by firoso
    Hello everyone! I've been contemplating writing a simple "event log" that takes a paramater list and stores event messages in a log file, trouble is, I forsee this file growing to be rather large (assume 1M entries or more) the question is, how can I implement this system without pulling teeth, I know that SQL would be a possible way to go. XML would be ideal but not really practical for scaleability if i'm not going nuts. Example Log Entry -----Time Date-------- ---------Sender----------------------- ---------Tags---------- --Message---------- 12/24/2008 24:00:00 $DOMAIN\SYSTEM\Application$ :Trivial: :Notification: It's Christmas in 1s

  • Is it possible to simulate TMenuBreak functionality with Dev Express TdxBarSubItems?

    - by mcmar
    In my application I'm dynamically adding new TdxBarSubItems based off of a SQL query. In some cases the result set is rather large so the menu fills the entire screen and sometimes has a down arrow to scroll the list. In a previous version of the code before switching to Dev Express, I was able to add TMenuBreak objects to make the list divide into columns. Is there a way to do this with Dev Express components?

  • How to make a nested query with an Entity that doesn't really exist (many-to-many)

    - by Calou
    Hi everyone, I'm new with Doctrine2 so my question can be easy to answer (I hope so). First of all, here the SQL query that I'd want : SELECT * FROM Document WHERE id NOT IN (SELECT document_id FROM Documents_Folders) Pretty simple isn't it ? The porblem is that my table 'Documents_Folders' is not an entity. In fact, it was create because I have a many-to-many relation between my entities 'Document' and 'Folder'. I tried several queries, but none worked. Thanks.

  • Count of products NOT sold...per store, per day over the past month

    - by user1893510
    I'm struggling with an interview question. 3 dimension tables (Product, Store and Date) and 1 fact table (Sales). The question asks for a T-SQL solution that will return the count of products not sold, per store, per day over the past month. At this point, my answer is futile but I've spent significant time trying to back into a solution, to no avail, and would like to close the loop. Any guidance is greatly appreciated.
