Production server error

Hello,
I have reports that have embedded code from a custom assembly.
In design, they work fine. When I deploy them and run them via the
Report Manager on production I get the following error in the cells
where I have this code running:
"Error in method xxxxxx - Request for the permission of type
System.Data.SqlClient.SqlClientPermission, System.Data,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
failed."
I have followed all previous articles, made changes to .config files,
etc., etc. Given the assembly full trust, etc. Still no luck.
Has ANYONE actually got this to work? Crystal reports was a pain, but
at least it worked!
Thanks for any help with this.
FabioIt sounds like you did not explicitly assert permissions to open a database
connection. Unless you assert (!) the permission explicitly, it will fail
with a security exception. Example for opening a connection to a SQL Server
in custom code / custom assemblies:
...
SqlClientPermission permission = new
SqlClientPermission(Permission­State.Unrestricted);
try
{
permission.Assert(); // Assert security permission !!!
SqlConnection conn = new SqlConnection("...");
conn.Open();
...
}
BTW: you don't need FullTrust for using the SqlClient in a custom assembly,
because the SqlClient is enabled for partial trust scenarios. Just check the
MSDN documentation on the SqlClientPermission class.

I am explicity asserting permissions. Here's the code I'm using. Am I
missing something?
Try
Dim permission As New
SqlClientPermission(Security.Permissions.PermissionState.Unrestricted)
permission.Assert()
'Use the MS data access app block to get the data reader
dr = _myDBAccess.ExecuteReader(_myConn,
CommandType.StoredProcedure, "Trader_GetTransByAssetID", New
SqlParameter("@.AssetID", nAssetID))
'Loop thru all transactions to build arraylist of
transaction objects
While (dr.Read())
objTrans = New Transaction(dr.GetInt32(COL_TRANSID),
dr.GetDateTime(COL_TRADEDATE), dr.GetSqlMoney(COL_DOLLARS).ToDouble,
sShareClass, 0.0, dr.GetSqlDecimal(COL_SHARES).ToDouble,
dr.GetSqlDecimal(COL_PRICE).ToDouble,
CType(dr.GetSqlInt16(COL_CALCSHAREBALANCE).ToString, Integer),
CType(dr.GetSqlInt16(COL_CALCCOSTBASIS).ToString, Integer))
arlTrans.Add(objTrans)
End While
Catch ex As Exception
_myErrorMessage += " Error in method
CDSC.BuildTransArray - " & ex.Message
Finally
'Clean Up
If Not (IsNothing(dr)) Then
dr.Close()
End If
End Try
Thanks for your help.|||OK, got it fixed.
You have to explicitly open the connection everywhere you use this. So,
we've got it added to every function/procedure within our assembly.
So not oly are we using the ExecuteReader, but we're opening the
connection each time as well.|||I have a similar problem, could you please give some example on this. when
you say
> So not oly are we using the ExecuteReader, but we're opening the

do you mean you declare explicitly
Dim cn as sqlconnection = new sqlconnection(connectionstring)
after sqlclientpermission
From your example,
Try
Dim permission As New
SqlClientPermission(Security.Permissions.PermissionState.Unrestricted)
permission.Assert()
-----
' Dim _myConn as sqlconnection = new sqlconnection(connectionstring)
(adding this solved your issue?)
----
'Use the MS data access app block to get the data reader
dr = _myDBAccess.ExecuteReader(_myConn,
CommandType.StoredProcedure, "Trader_GetTransByAssetID", New
SqlParameter("@.AssetID", nAssetID
Appreciate your help on this.

Process throttling

Hi,
We have an application accessing an SQL Database. The problem is that due to
a flaw in design, when queries are submitted we get 100% cpu usage on the
server. Is there any way to limit processing power for specific access?
Thanks
NichHi,
Try to identify the SQL's which is doing a table scan. Then based on the
where condition in the select statement
create useful indexes, this will definitely reduce the Disk reads, which in
turn reduces the CPU usage.
Thanks
Hari

Thanks, we will be using the Index tune-up wizard in fact, but does any one
know if a physical cpu usage limit can be set in any way apart from using
indexes to maximize table access speed

you could also try lowering the priority of the sqlserver process.
i think it would be nice if we could set priority levels for db user account

so that certain users couldn't hog db resources or certain users' queries wo

get higher priority than others.
