Hi All

I am facing SQL Server Timeout exception.

try
{

SetStoredProcCommand(SPRetrieveIntSchedReport, DatabaseConfigKey);

AddInParameter("@FromDate", DbType.DateTime, schedule.FromDate);

AddInParameter("@ToDate", DbType.DateTime, schedule.ToDate);

AddInParameter("@ApplnType", DbType.String, schedule.ApplnType);

IDataReader dataReader = ExecuteReader();

while (dataReader.Read())
{ .....}
}
When the control reaches the data reader its taking much time to enter the WHILE loop, and some times its getting in and its done fine,but sme times facing this SQL SERVER TIMEOUT EXCEPTION.

please help.

Thanks in advance.

You can increase the timeout on your connection/command, or better still optimise your proc as you may be doing a table scan or something similar - no way to tell from your code.

Thanks

Set it to 0 to run the query indefinately .ie until you get the result.

When you fail to plan, you are planning to fail.

use the sqlcommand CommandTimeOut property....

ie

your_cmd_obj.CommandTimeOut=0

In which case I suggest you consider some of the followng:

- do you need to return all the data at once?
- could the underlying data be denormailised into reporting tables?
- could some of the data be cached?
- could the indexing be improved?

I am fairly certain that if the query times out, and you are displaying the data on a web page it will be pointless, as nobody wants to wait ages for a page to load.

Hopefully this may guide you to a solution

But sometimes i can get it perfectly, and sometimes it throws the timeout exception ?

Thanks

What about load on the sql server? Any locking causing problems, that sort of thing? Without actually being there its difficult to pinpoint where the problem is.

Hi,

"I want that my website should be viewable to 10,000 persons at the same time.
Also they might insert, or delete data from the database.
How will you do it".

This was one of the questions posed in an interview.
Apart from poolsize, what should I answer for the above question.

Hmm..
Did you ever check top left corner of in Codeproject Sites, that 6,006,898 members and growing! (24,514 online)
It means all online user may view the sites same times and can insert post, replying on post [ AS I am doing ], etc....

This is very common behavior of web sites, for large number of user you many need a strong backend server and all user need to maintain by session only Smile | :)

You can also set the maximum number of request in IIS.  Create Separate Application Pool for the Site, assign that Application pool, change the Application pool Maximum Request Limit.

actually if you are filling that data on page load then you are not using page.ispostback check there... thats why your older data gets filled in texboxes you dont need to stop refresh behaviour of server side button...
its a logical problem not the control related..
