AW: [mapguide-users] 2.0.1 / IIS / .NET instability?

Sun Jul 20 03:30:47 EDT 2008

Hallo,

below the vb program and the batch file we use, any suggestions for a better
solutions are really welcome

thanks,

Hans

===================================

batch file for restarting MGOS like this:

netsh interface set interface LAN1 disable

taskkill /F /FI "SERVICES eq MapGuideServer2.0"

net stop W3SVC

net stop pgsql-8.2

net stop MapGuideServer2.0

net start W3SVC

net start pgsql-8.2

net start MapGuideServer2.0

netsh interface set interface LAN1 enable

===================================

this batch file is started by a little vb program (vb.net 2008):

- create a form and put the webbrowser control on it:

Public Class frmMonitor

    Dim LogFileName As String = Application.StartupPath &
"\LOG\monitorlog.txt"

    Dim DocLoaded As Boolean

    Private Sub frmMonitor_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

        Me.WindowState = FormWindowState.Minimized

        If System.IO.File.Exists(LogFileName) = False Then

            System.IO.File.CreateText(LogFileName)

        End If

        TimerMonitor.Interval = 30000

        TimerMonitor.Start()

    End Sub

    Private Sub TimerMonitor_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles TimerMonitor.Tick

        ' Mapguide Test / IIS Test / PostgreSQL DB Test

        MapGuide_IIS_DB_Test()

    End Sub

    Sub MapGuide_IIS_DB_Test()

        Dim TestSeite As String = ""

        Dim strPos1 As Integer = -1

        Dim StartZeit As Date = Date.Now

        Dim ZeitDiff As Long = 0

        If WebBrowserTest.IsOffline = False Then

            Try

                DocLoaded = False

                Dim u As New Uri("http://localhost/webmonitor/start.aspx")

                DocLoaded = False

                WebBrowserTest.Navigate(u)

                While DocLoaded = False

                    Application.DoEvents()

                    ZeitDiff = DateDiff(DateInterval.Second, StartZeit,
Date.Now)

                    If ZeitDiff > 10 Then

                        WebBrowserTest.Stop()

                        WriteLog("IIS / MapGuide Server / DB neu gestartet")

                        ServerAppRestart()

                        Exit Sub

                    End If

                End While

                TestSeite = WebBrowserTest.DocumentText

                strPos1 = -1

                If Trim(TestSeite) = "" Then

                    strPos1 = -10

                Else

                    strPos1 = InStr(TestSeite, "Seite erfolgreich geladen")

                End If

                Select strPos1

                    Case 0

                        WriteLog("IIS / MapGuide Server / DB neu gestartet")

                WebBrowserTest.Stop()

                ServerAppRestart()

            End Try

        Else

            WebBrowserTest.Stop()

            WriteLog("IIS / MapGuide Server / DB neu gestartet")

            ServerAppRestart()

        End If

    End Sub

    Sub ServerAppRestart()

        TimerMonitor.Stop()

        System.Diagnostics.Process.Start(Application.StartupPath &
"\mgosiisdbrestart.bat")

        TimerMonitor.Interval = 30000

        TimerMonitor.Start()

    End Sub

    Private Sub btnEnde_Click(ByVal sender As System.Object, ByVal e As

            Dim LogWriter As New System.IO.StreamWriter(LogFileName, True)

Hi,

Glad I’m not the only one experiencing these problems
. Any chance that your
VB monitoring program can be made available to the group?

Thanks,

Andy

Subject: AW: [mapguide-users] 2.0.1 / IIS / .NET instability?

Hello,

we are using MGOS 2.0.1 / IIS7 / .NET whith an asp solution and the ajax
viewer. We have similar errors when using raster images (GDAL , MrSID and
Tiff mages), I think these problems where already discussed a little time
ago, but as far as I have seen there are no solution yet ???

At the moment we use a little monitoring program written in VB to check
every 30 seconds if mgserver is responding using a simple test layout.

Unfortunately restart of mgserver results in loss of session data so this is
not a perfect solution. I would be very interested in some other ideas how
to restart mgserver without loosing all user data, are there any suggestions
??

Thanks,

Hans Mörschell

Hi All,

I migrated my public demo server to 2.0.1 a few weeks ago.  Since then, I
have found MapGuide to be much more unstable than it had been previously.
The service completely locks up (although appears started to Windows) and
cannot be restarted using normal methods and PSKill is the only solution to
restarting it.   When looking at the server, I usually see an unhandled
exception error dialog with mgserver.exe the faulting module.   The one
thing that is different now is that we’re using a Fusion layout instead of a
standard layout for a site that is regularly accessed.  The Windows event
logs don’t yield many clues, but the MGOS error.log has many of these
entries:

<2008-07-17T00:06:08>   Fusion Viewer   xxx.127.xxx.41  Anonymous

 Error: Invalid argument(s):

        The value cannot be less than or equal to zero.

 StackTrace:

  - MgRenderingServiceHandler.ProcessOperation line 83 file

\services\rendering\ServerRenderingService.cpp       Invalid argument(s):

The value cannot be less than or equal to zero.

I know some folks were working on something to determine if the mgserver
service had locked up and, if so, restart it.  Was anybody successful in
making something like this work?  It’s not fun to hit your map site only to
find it not working.

Thanks,
