Handle Server Downtime For Several Websites?
Nov 2, 2010
My company is planning on having some planned down time, because of some server migrations. Their are about 20 different web applications (internet, and intranet). Any of which can go down at any one time because of the server migration of applications.
So, does anyone know if their is a way to provide a generic message to users if a particular application is down? Like a popup message box, or generic page for that particular application? The idea is to not write 20 different popups or 20 different Fyi-Web pages. But one single page or popup informing that the application is down.

We have a huge ASP.NET web application which needs to be deployed to LIVE with zero or nearly zero downtime. Let me point out that I've read the following question/answers but unfortunately it doesn't solve our problems as our architecture is a little bit more complicated.
Let's say that currently we have two IIS servers responding to requests and both are connected to the same MSSQL server. The solution seems like a piece of cake but it isn't because of the major schema changes we have to apply from time to time. Because of it's huge size, a simple database backup takes around 8 minutes which has become unacceptable, but it is a must before every new deploy for security reasons.
Currently the best idea we came up is buying another SQL server which would be set up as a replica of the original DB. From the load balancer we would route all new traffic to one of the two IIS webservers. When the second webserver is free of running sessions then we can make deploy the new code. Now comes the hard part. At this point we would go offline with the website, take down the replication between the two SQL servers so we directly have a snapshot of the database in a hopefully consistent state (saves us 7.5 of the 8 minutes). Finally we would update the database schema on the main SQL server, and route all traffic via the updated webserver while we are upgrading the second webserver to the new version.
also share your thoughts regarding this solution. Can we somehow manage to eliminate the need for going offline with the website? How do bluechip companies with mammuth web applications do deployment?
Edit 1 (2010.01.12):
Another requirement is to eliminate manual intervention, so in fact we are looking for a way which can be applied in an automated way.
Let me just remind you the requirement list:
1. Backup of database
2a. Deploy of website
2b. Update of database schema
3. Change to updated website
4 (optional): easy way of reverting to the old website if something goes very wrong.

Im using the MySql Membership-,Role- and ProfileProvider. If the mysql-server goes offline the site crashes (ofcourse). But when the mysql-server gets back online the site still crashes, complaining that the Role provider cant get initialized because of missing or incorrect schema. If I then make a meaningless change to the web.config (like adding a space somewhere) the site works again.

the account we use to copy/publish websites to our web server is not allowing us access to push websites. I've added this account to the permissions in the links listed in the below link, but i don't have success when trying to push remotely. When the account is in the local admins account, everything works flawlessly, but we are not allowed to have it in there. http://social.msdn.microsoft.com/Forums/en-US/vssetup/thread/31be047e-4716-4974-b8a1-be0111b50199 I've googled and searched a lot for this particular error, but am not finding an answer that helps. We get this error, 'Unable to create the Web 'http://edea01/test/planning'. You are not authorized to perform the current operation', and the above link is the scenario that matches mine the most. I don't do develompment work, but am asked to figure out this connection problem.

I'm thinking of a architectural way of displaying messages in our application (Flex-Asp.NET-SqlServer), mostly messages that announce for instance a downtime.Currently I was thinking of creating a table FlexMessage that holds the name of a message (based on that name I now where to put in Flex) and the value (the message itself). As a result however, someone will have to create these messages and also delete them when they are no longer valid. So, thinking further, I thought of creating messages having a startdate and enddate, so an interval in which they need to be displayed. Like this, someone could login to the management part and create a message that needs to be displayed from a certain date until a certain date.I could also hardcode it in the Flex Application, but that would mean putting a new build online (of the swf) each time something changes with a certain message.

I am wondering if ASP.NET is a good choice to build small such as personal websites, blogs, photo gallery to medium websites such as online booking, medium sort of facebook!, etc?I have heard that ASP.NET and MS SQL Server take more resources than PHP and MySQL which means it could be only good for rich people who are able to pay for these resources!

As far as I can work out I should be able to copy a web project/application to my IIS Web server and be able to see it as I do when designing it on my development computer.
The problem is once I copy the folder over to my web server and then try to view it the browser it says Error 404 not found. There must be a real simple fix for this. I would like to be able to develop ASP.NET sites using the Visual Web Developer instead of Dreamweaver but this little issue is stopping me.

I'm building a browers-based game that will need to constantly be updating EVERYONE'S accounts regularly; what is the best way to go about doing this? Creating a process that runs every time someone goes to a page on my site slows down the load time immensely. Do I need to create a windows scheduled task that calls this/these process(es)? It will need to constantly run.

When setting up asp.net error handlers for things like 404 errors, it is more 'efficient' to do this in IIS, or handle it in the Global.asax Application_Error event? I know the latter will be called, and I want to log this information in a database, but should I then just return without any redirect and let IIS do the redirect, or would it be better to do a response.redirect inside application_error once we've logged it?

We have a page where you can insert a record. On the page we have validation to prevent duplicate IP addresses from being submitted for the same location. Now on the procedure side i have a condition that is checked, if you supply data that already exists for a location, then it will be updated. If its not then its inserted.. this all works fine.. issue now that i noticed is that we have a table that is part of the process, if you select say 3 from a drop down for number of emails, then when you submit the page, i have a loop for each of those emails and they are inserted into the email table as individual records.. works great also.. BUT here is my problem.. if i submit say an existing set of data and this time i provide say 1 email vs 3 from the previous time, i need to handle that in the procedure, so that the 3 are deleted and only 1 is now inserted and linked to that record..
Hope this makes sense..
Since im doing a foreach loop based on that dropdown selection, now when i look at my table im getting only 1 record in the email table... since the logic is within the procedure, when the page calls the procedure, it finds tha the record exists, deletes all the records, then only inserts the last record.
Example.
I submit the page with 3 emails today.. everything works and goes in as expected, there are 3 emails and record is created without issues..
Tomorrow someone else comes in from my team and decides to enter the same record data, thats not a problem, because there is an update statement if it already exists.. BUT this time they entered only 2 emails.. the 2 new emails are inserted / updated in the table, but the 3rd email is still in there.. its not removed.. so i tried to add a if exists condition to my procedure, but since the procedure is called in my foreach loop, the first loop sees the records, deletes them and inserts the first email, then on the 2nd foreach loop it deletes that last entry and inserts the next, so by the time it goes thru it has deleted everything it inserted and only captures the last record..
Just tried it now.. and since there was already 1 record in the table, i chose to add 4.. the end result should be 4, but i now have 5 records in there.. the first one and the 4 new ones..

I have unexpectedly found that I cannot access my data tables from VS 2008. A window comes up saying "The server version is not supported. Only servers up to Microsoft SQL server 2005 are supported". Also, as a consequence I imagine, two web sites which refer to datatable have stopped working.
Has my ISP updated to an SQL version that VS 2008 can't handle ?

How can I handle more than 4k of text on the new SQL Compact Edition 4? nvarchar only supports 4k and when I change to ntext, I get the same exception as I get using nvarchar(4k), when using the Microsoft.Data wrapper included with Microsoft WebMatrix. Should it normally work using ntext?

Trying to figure out how to handle data returned for a site search from a description field. I don't think I want to display all the text from the description field, but I also don't want to "chop" a word in half. How do I get the first 100 characters, plus a few extra letters if needed to prevent a word from being chopped in half. In some cases, the description field is less than 100 characters, so all the text will be displayed. However, if the description does need to be chopped at 100, I'd like to finish the word and add ... to indicate that there is more text.

What's a good way to handle "paging" in a web app? I want the user to see only rows 1-20 from a data query, but they can then choose to view rows 21-40, then 41-60, etc.
More detail:
I'm building an app that will return a bunch of news articles from a database.
I will be converting the query results into XML and transferring it via web service. I will then convert the xml into an HTML table to show in the browser.
The query will return hundreds, but I assume it must be more efficient use of bandwidth and server resources to show only 20 at a time.

I will consolidate several web sites into one. I have a brief design in mind. Top row: banner sencon row (main menu): home, Applications (drop down-accounting, employeement, sports etc), Your Account In 3rd big row, at left side, there will be links (or just menu listed down) In the middle, there will be contents displayed related to top and left menu. for example, If a user selects application->Sports from 2nd row, then there will be links of Tennis, Golf, Volley ball appeared in the left. if the user click 'Golf' then the center page will display contents related to golf. I am not sure it will work with multiple sitemaps or database driven menu structure etc. How can I do that? Is it a good design?
