Hi all
I have a small scheduling application that I have written which will be
running on a Windows 2003 server. This application is started at
different times by an 'autosys' job (though I am testing by
manually starting the app from the server, that is logging into the
server, and running).
This app depending on available resources (txt, xml data files), starts
simple exe console apps which load simple data feeds into an SQL db. In
this operation file IO operations are required (such as copying and
directory creation) by the scheduler app, and simple files resource
checks (FileExists(xxx .txt), are carried out by the simple console
apps. All works as expected when run from my workstation.
The problem I have is that the console apps raise IO security
exceptions when run on the server. That when I deploy the scheduler and
associated console apps, the console apps raise exceptions. These
simple console apps are started in my scheduler app by using the
System.Diagnost ics.Process CLASS. The scheduler does not cause problems
although it carries much of the IO work (the app I start manually). The
app which are started by the scheduler are the ones causing all the
problems.
Code to start the process which run the console apps:
DateTime start = DateTime.Now;
try
{
// run the appropriate macro
System.Diagnost ics.Process macro = new
System.Diagnost ics.Process(); macro.StartInfo .FileName =
fp.MacroFilePat hName;
macro.StartInfo .Arguments = this.feedProces sXMLDirprocess_ " +
fp.FeedFileName + ".xml";
macro.StartInfo .Arguments += " " + fp.ProductionRu n.ToString();
macro.StartInfo .CreateNoWindow = true;
macro.Start();
macro.WaitForEx it(); //macro.WaitForEx it(5000)
// keep track of all log files.
this.logs.Add(f p.LogFileDir + "\\" +
this.feedProces sXMLLogFileName Header + fp.LogFileName +
FeedProcess.dat eToDirString(th is.currentDate, fp.FeedFileDest inationDirForma t)
+ ".xml"); this.numMacros+ +;
}catch (Exception ex)

From where are you attempting to load the target executable? (i.e.: What
does fp.MacroFilePat hName return?)

Hi Nicole
I am attempting to run target exe on the some server (same dir in
fact). That is to sat the first exe is running(schedul ing program), and
it is attempting to start a second exe. The first app does not seem to
be raising any security exception, whereas the exe's started by this
app are causing problems.
The exe's are starting, but failing when an IO operations are
attempted.
thanks

Are both the exe's loaded from a local disk or from a network share?
Willy.
Hi Willy,
Both exes are loaded from the same folder at present, on the win 2003
server.
thanks

I understand that, but the question is - do you run the code on the win 2003
server it is loaded from, or do you load the code from the server and run it
on another machine?
It looks like you are doing the latter, which obviously throws a
"FileIOPermissi on" security exception because (by default) code loaded from
non local storage has no FileIOPermissio n.
Willy.
Hi Willy
The code will run on the server itself, and is local on that server.
thanks
If the "macro" assembly is being loaded from a local path on the same
machine*, is it possible that the machine's CAS policy has been altered so
that locally run assemblies are no longer automatically granted unrestricted
permissions? If you can't tell from examining the CAS policy yourself, it
would probably be a good idea to ask the machine administrator about this.
*This means not even a UNC path pointing to a share on the same machine, but
a strictly local path like "C:\SomeDirecto ry\SomeAssembly .exe".
