Invoking a batch file from Report

Hi !

I have to invoke a batch file (.bat) when an ad-hoc report is executed. I've currently written a .Net code for invoking (using System.Diagnostics.Process) the batch file. The rdl file calls the method.

When I run the report from Report Designer the batch file is getting executed. But if I deploy it in the Reporting Server and run the report through Web Interface the batch file is not getting executed.

Looks like some security issue. Can someone provide a solution for this?

Thanks.

Where did you place the batch file ? All commands executed either in Script or custom code or executed on the server not on the client.

|||Just a suggestion on how to execute the .bat file. Could′t you use a SQL Agent job instead and call sp_start_job from a dataset in the report?|||

Hi Jens,

Thanks for the reply.

I placed the batch file in the server. I also moved the code (to invoke a batch file using System.Diagnostics.Process class) to a VB.Net dll and tried invoking the function from the rdl. The function is not getting invoked. I also added SecurityPermissionAttribute to the class. Is there any other Security permission that needs to be added for the code to be accessed.

Please find below the sample:

Public Shared Function fnRunSPX(ByVal x As String, ByVal y As String, ByVal z As String, ByVal w As String)

Dim Pro As New System.Diagnostics.Process

Dim Elog As New System.Diagnostics.EventLog

If Not Elog.SourceExists("BillingDateBatch") Then

Elog.CreateEventSource("BillingDateBatch", "Application")

End If

Dim EventLog1 As New System.Diagnostics.EventLog

EventLog1.Source = "BillingDateBatch"

EventLog1.Log = "Application"

EventLog1.WriteEntry("Success", System.Diagnostics.EventLogEntryType.SuccessAudit)

Pro.StartInfo.FileName = "C:\\batch.bat"

Pro.StartInfo.Arguments = x + " " + y + " " + z + " " + w

Pro.Start()

Pro.WaitForExit()

End Function

Even the evenlogging (present in teh above code) does not happen. Please let me know if you have any questions.

Thanks,

Aravind

Invalid buffer received from client.

I'm having seriouos trouble after installing SP4. I have an application writ
ten in ASP.NET 1.1 which worked fine with SQL 2000 SP3, but after upgrading
to SP4, the application totally crashed while trying to access the database.
It gives an error saying a
severe error has occued on the server. The
event log on the server has the following logged:
Error: 17805, Severity: 20, State: 3
Invalid buffer received from client.
For more information, see Help and Support Center at http://go.microsoft.com/fwlin
k/events.asp.
I'm sure it's SP4 because after I reinstalled SQL Server with SP3, everythin
g worked fine again. The server is running Windows 2003 SP1.
Anyone else having this problem or have a solution?Sp4 reduces the network packet size to 32767. Consider adjusting your app to
avoid the error.
<quote>
In SP4, the maximum value for the network packet size option (set using
sp_configure) is 32767. This is slightly less than half the previous maximum
of 65536. During upgrade, existing values larger than 32767 will
automatically be adjusted to 32767. If a script attempts to use sp_configure
to set a value larger than 32767 but less than or equal to 65536, the value
will also be set to 32767. Setting the network packet size to a value larger
than 65536 results in an error.

There's used to be a bug even when the network packet size was set to
65535...

Do you have an example of how to change the packet size to 32767 - is it thr
ough the connection string? At the moment, it has packet size set to 4096.

According to the article, you might want to limit each of your insert batch
to 32767 rows.

Here's my connection string:

I tried the packet size 2048, 1024, 768 but they all return the same error.
Any help is greatly appreciated!

If you post your code (.Net call + sql), someone will take a closer look.

But now it runs extremely slow and frequently timeout. Any solution to this
problem as well?

The problem was caused by creating an SQL parameter using DbType instead of
SqlDbType. I was trying to create a generic data provider that connects to b
oth Oracle and SQL Server. Now I think I have to map the individual DbType t
o SqlDbType.
Anyway, thanks for your help!! Much appreciated!
