  • GroupWise 6.5 IMAP Service Shuts Down-Needs Constant Restarting

    - by Jeffrey Majette
    I have an issue with my aging (and soon to be replaced) GroupWise 6.5 system. The IMAP service in the GWIA tends to periodically shut down, requiring that I restart the service. When IMAP is down, my end users who use Blackberry BIS cannot send or receive email on their devices. It's a royal pain to have to restart the IMAP service several times a day. The GWIA logs do not seem to indicate a problem. I thought I was on to something yesterday. I discovered that the gwia.cfg file located in SYS:SYSTEM was actually from GW 6.0. The gwia.cfg in DOMAIN\WPGATE\GWIA was titled for GW 6.5 when opening the file for editing. I changed the generic placeholder info in the file to match my environment and restarted the gwia. However, it made no difference in performance. The IMAP service shuts down about 30 minutes after the last restart. I know this version of GW is antiquated. We are in the process of migrating to Google Apps. But, if anyone has an idea that could fix this issue, I and my end user community would be forever grateful!

  • Do Managed/Unmanaged Switch Really need to have their Cabinets/Racks?

    - by Googooboyy
    Hi guys, I'm new to managed switches and I recently inquired an IT consultant to setup my new office network. For the records, the new office network spans 2 floors, thus he recommended utilising ONE managed switch with a rack/cabinet housing, and the rest using unmanaged switches. Anyways, my main question is: does a managed switch really need to be housed on a rack, or in its own cabinet, to function efficiently? Btw, what are the pros/cons of having a rack/cabinet?

  • Nagios: turn off service checks/display on down hosts

    - by Alien Life Form
    I want to to tweak nagios in such a way that all checking stops (with services not displayed, or displayed as unknown) for any down node. Said differently I only want to see one alert for a down host instead of 1 (down) + n (1 for every service). Note that I am interested in service display/status, not only in turning off notifications. Rationale: we use the nagios firefox/chrome plugin to monitor status and nagios' behavior is too noisy giving readings like these (because every node has 20 services): 3 down, 1 unreachable, 4 warnings, 87 critical This means that the 7 critical services on up node (the problem is on the service) are swamped in a slab of red services which are critical only because they sit on a node that's down/unreachable. What I'd rather like to see is: 3 down, 1 unreachable, 80 unknown, 4 warnings, 7 critical Or even 3 down, 1 unreachable, 4 warnings, 7 critical I have looked in service dependencies but I did not fine a way to describe: "make all services on a alive-host dependen on the status of the host check". I found the problem discussed here, where one of the participants thought it was a nagios bug, and here where one of the participants thought it was "as designed". As things are, I am just interested in the effect, much less in the design philosophy. Note that this nagios is checking hundreds of nodes, so the maintainablilty of the solution is also important. TIA and cheers.

  • Solaris 11 pkg fix is my new friend

    - by user12611829
    While putting together some examples of the Solaris 11 Automated Installer (AI), I managed to really mess up my system, to the point where AI was completely unusable. This was my fault as a combination of unfortunate incidents left some remnants that were causing problems, so I tried to clean things up. Unsuccessfully. Perhaps that was a bad idea (OK, it was a terrible idea), but this is Solaris 11 and there are a few more tricks in the sysadmin toolbox. Here's what I did. # rm -rf /install/* # rm -rf /var/ai # installadm create-service -n solaris11-x86 --imagepath /install/solaris11-x86 \ -s [email protected] Warning: Service svc:/network/dns/multicast:default is not online.

  • Calling SQL Azure's stored procedure in silverlight

    - by sweetsweet
    I have a silverlight application to call the SQL Azure's stored procedure and show the data. I use the service to call stored procedure, and it is working when it is run at VS 2008. But when I integrate in php page, the data is not shown. I think the service is not running. How can I call SQL Azure stored procedure without using service? I cannot use ADO.Net Entity Domain Model and LINQ to SQL(I don't have permission to access that database in GUI). I cannot connect to SQL Azure, so which method can I use to call SQL Azure stored procedure in silverlight? Please give me the information. {I don't know very much about that silverlight. To take the detailes of my project. I want to call SQL Azure's stored procedure. So, I tried to call that Stored Procedure from ADO.Net Entity Domain Model. The problem is I cannot access that SQL Azure database. It show "Buit_in function suer_sname is not supported in this version of SQL server. Therefore, I connect to that Stored Procedure in code beind and call that function in Service and to use that data in presentation layer, I add service reference in silverlight(I mean the service is at the same project). It is perfectly working when it is running at VS. So,I take out xap file and call that xap file in php. The silverlight is running in that PHP page but the data is not shown. I think the service is not hosted. So, how can I solve my problem? I use xampp to run my php page. }

  • European e-government Action Plan all about interoperability

    - by trond-arne.undheim
    Yesterday, the European Commission released its European eGovernment Action Plan for 2011-2015. The plan includes measures on providing deeper user empowerment, enhancing the Internal Market, more efficiency and effectiveness of public administrations, and putting in place pre-conditions for developing e-government. The Good - Defines interoperability very clearly. Calls interoperability "a pre-condition for cross-border eGovernment services" (a very strong formulation) and says interoperability "is supported by open specifications". - Uses the terminology "open specifications" which, let's face it, is pretty close to "open standards" which is the term the rest of the world would use. - Confirms that Member States are fully committed to the political priorities of the Malmö Declaration (which was all about open standards) including the very strong action: by 2013: All Member States will have incorporated the political priorities of the Malmö Declaration in their national strategies. Such tight Action Plan integration between Commission and Member State priorities has seldom been attempted before, particularly not in a field where European legal competence is virtually non-existent. What we see now, is the subtle force of soft power rather than the rough force of regulation. In this case, it is the Member States who want Europe to take the lead. Very refreshing! Some quotes that show the commitment to interoperability and open specifications: "The emergence of innovative technologies such as "service-oriented architectures" (SOA), or "clouds" of services,  together with more open specifications which allow for greater sharing, re-use and interoperability reinforce the ability of ICT to play a key role in this quest for effficiency in the public sector." (p.4) "Interoperability is supported through open specifications" (p.13) 2.4.1. Open Specifications and Interoperability (p.13 has a whole section dedicated to this important topic. Open specifications and interoperability are nearly 100% interrelated): "Interoperability is the ability of systems and machines to exchange, process and correctly interpret information. It is more than just a technical challenge, as it also involves legal, organisational and semantic aspects of handling  data" (p.13) "standards and  open platforms offer opportunities for more cost-effective use of resources and delivery of services" (p.13). The Bad Shies away from defining open standards, or even open specifications, the EU's preferred term for the key enabler of interoperability. Verdict 90/100, a very respectable score.

  • Stumped by "The remote server returned an error: (403) Forbidden" with WCF Service in https

    - by RJ
    I have a WCF Service that I have boiled down to next to nothing because of this error. It is driving me up the wall. Here's what I have now. A very simple WCF service with one method that returns a string with the value, "test". A very simple Web app that uses the service and puts the value of the string into a label. A web server running IIS 6 on Win 2003 with a SSL certificate. Other WCF services on the same server that work. I publish the WCF service to it's https location I run the web app in debug mode in VS and it works perfectly. I publish the web app to it's https location on the same server the WCF service resides under the same SSL certificate I get, "The remote server returned an error: (403) Forbidden" I have changed almost every setting in IIS as well as the WCF and Web apps to no avail. I have compared setting in the WCF services that work and everything is the same. Below are the setting in the web.config for the WCF Service and the WEB app: It appears the problem has to do with the Web app but I am out of ideas.

  • Web service using Data Dynamics ActiveReports occasionally slows down

    - by Swoop
    My company is running into a problem with a web service that is written in C#/ASP.Net. The service receives an identity key for data in SQL Server and a path to generate and save a PDF report for this data. In most cases, this web service returns results to the calling web pages very quickly, usually within a few seconds max. However, it seems to occasionally hit a significant slowdown. The web application calling the web service will generate a timeout error when this slowdown occurs. We have checked and the PDF does get created and saved to the server, so it looks like the web service eventually finishes executing. It seems to take about 1 to 2 minutes for processing to have completed. The PDF is generated using ActiveReports from Data Dynamics. Wwhen this problem occurs, making a small change to the web service's config file (ie, adding a blank space to a connection string line) seems to restart the web service and everything is perfectly ok for a period of time afterwards. Other web applications that are running on the same web server do not seem to experience this type of behavior, only this particular web service. I have added the code for the web service below. It is basic calls to 3rd party libraries. We are not able to recreate this problem in test. I am wondering what might be causing this issue? [WebMethod] public string Publish(int identity, string transactionType, string directory, string filename) { try { AdpConnection Conn = new AdpConnection(ConfigurationManager.AppSettings["myDBConnString"]); AdpCommand Cmd = new AdpCommand("storedproc_GetData", oConn); AdpParameter Param; Cmd.CommandType = CommandType.StoredProcedure; Param = Cmd.CreateParameter("@Identity", DbType.Int32); Param.Value = identity; Cmd.Parameters.Add(oParam); Conn.Open(); string aResponse = Cmd.ExecuteScalar().ToString(); Conn.Close(); if (transactionType == "typeA") { //Parse response DataSet dsResponse = ParseDataResponse(aResponse); //dsResponse.WriteXml(@ConfigurationManager.AppSettings["DocsDir"] + identity.ToString() + ".xml"); DataDynamics.ActiveReports.ActiveReport3 rpt = new DataDynamics.ActiveReports.ActiveReport3(); rpt.LoadLayout(@ConfigurationManager.AppSettings["myReportPath"] + "TypeA.rpx"); rpt.AddNamedItem("ReportPath", @ConfigurationManager.AppSettings["myReportPath"]); rpt.AddNamedItem("XMLSTRING", FormatXML(dsResponse.GetXml())); DataDynamics.ActiveReports.DataSources.XMLDataSource xmlds = new DataDynamics.ActiveReports.DataSources.XMLDataSource(); xmlds.FileURL = null; xmlds.RecordsetPattern = "//DataPatternA"; xmlds.LoadXML(FormatXML(dsResponse.GetXml())); if (!System.IO.Directory.Exists(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\")) { System.IO.Directory.CreateDirectory(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\"); } string sXML = FormatXML(dsResponse.GetXml()); StreamWriter sw = new StreamWriter(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".xml", false); sw.Write(sXML); sw.Close(); rpt.DataSource = xmlds; rpt.Run(true); DataDynamics.ActiveReports.Export.Pdf.PdfExport xPdf = new DataDynamics.ActiveReports.Export.Pdf.PdfExport(); xPdf.Export(rpt.Document, @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"); } } catch(Exception ex) { return "Error: " + ex.ToString(); } return @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"; }

  • How do I use an ADO.NET managed provider in Excel?

    I have an ADO.NET Managed Data Provider that is registered in machine.config in DbProviderFactory - It is available for use from, say, Analysis Services, so I know it is correctly registered. However, I need to be able to query the managed provider from Excel, but the managed provider doesn't appear as a choice from Data Link Properties | All Ole Db Providers. How do I get an ADO.NET Managed Data Provider to appear there, or is there another technique I need to use? Thanks in advance, Eli.

  • How do I avoid the loader lock?

    - by Mark0978
    We have a managed app, that uses an assembly. That assembly uses some unmanaged C++ code. The Managed C++ code is in a dll, that depends on several other dlls. All of those Dlls are loaded by this code. (We load all the dll's that ImageCore.dll depends on first, so we can tell which ones are missing, otherwise it would just show up as ImageCore.dll failed to load, and the log file would give no clues as to why). class Interop { private const int DONT_RESOLVE_DLL_REFERENCES = 1; private static log4net.ILog log = log4net.LogManager.GetLogger("Imagecore.NET"); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr LoadLibraryEx(string fileName, IntPtr dummy, int flags); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr FreeLibrary(IntPtr hModule); static private String[] libs = { "log4cplus.dll", "yaz.dll", "zlib1.dll", "libxml2.dll" }; public static void PreloadAssemblies() { for (int i=0; i < libs.Length; ++i) { String libname = libs[i]; IntPtr hModule = LoadLibraryEx(libname, IntPtr.Zero, DONT_RESOLVE_DLL_REFERENCES); if(hModule == IntPtr.Zero) { log.Error("Unable to pre-load '" + libname + "'"); throw new DllNotFoundException("Unable to pre-load '" + libname + "'"); } else { FreeLibrary(hModule); } } IntPtr h = LoadLibraryEx("ImageCore.dll", IntPtr.Zero, 0); if (h == IntPtr.Zero) { throw new DllNotFoundException("Unable to pre-load ImageCore.dll"); } } } And this code is called by public class ImageDoc : IDisposable { static ImageDoc() { ImageHawk.ImageCore.Utility.Interop.PreloadAssemblies(); } ... } Which is static constructor. As near as I can understand it, as soon as we attempt to use an ImageDoc object, the dll that contains that assembly is loaded and as part of that load, the static constructor is called which in turn causes several other DLLs to be loaded as well. What I'm trying to figure out, is how do we defer loading of those DLLs so that we don't run smack dab into this loader lock that is being kicked out because of the static constructor. I've pieced this much together by looking at: http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/dd192d7e-ce92-49ce-beef-3816c88e5a86 http://msdn.microsoft.com/en-us/library/aa290048%28VS.71%29.aspx http://forums.devx.com/showthread.php?t=53529 http://www.yoda.arachsys.com/csharp/beforefieldinit.html But I just can't seem to find a way to get these external DLLs to load without it happening at the point the class is loading. I think I need to get these LoadLibrary calls out of the static constructor, but don't know how to get them called before they are needed (except for how it is done here). I would prefer to not have to put this kind of knowledge of the dlls into every app that uses this assembly. (And I'm not sure that would even fix the problem.... The strange thing is that the exception only appears to be happening while running within the debugger, not while running outside the debugger.

  • Converting Luabind to C#?

    - by themarshal
    Has anybody tried converting Luabind to C#? Is such a thing even possible? I've got an application that I want to convert so that it can run in a completely managed environment, but most of the game logic relies upon Lua scripts, and the application uses Luabind to manage the back-and-forth. I'm not familiar enough with Lua or Luabind to know what's involved. Am I on a fool's errand here?

  • Is there a common practice how to make freeing memory for Garbage Collector easier in .NET?

    - by MartyIX
    I've been thinking if there's a way how to speed up freeing memory in .NET. I'm creating a game in .NET (only managed code) where no significant graphics is needed but still I would like to write it properly in order to not to lose performance for nothing. For example is it useful to assign null value to objects that are not longer needed? I see this in a few samples over Internet. Thanks for answers!

  • Blittable Vs. Non-Blittable in IL

    - by Michael Covelli
    I'm trying to make sure that my Managed to Unmanaged calls are optimized. Is there a quick way to see by looking at the IL if any non-blittable types have accidentally gotten into my pinvoke calls? I tried just writing two unmanaged functions in a .dll, one that uses bool (which is non-blittable) and one that uses ints. But I didn't see anything different when looking at the IL to let me know that it was doing something extra to marshal the bool.

  • Most efficient way to connect an ISAPI Dll to a windows service

    - by Mike Trader
    I am writing a custom server for a client. They want scalability so I must use a thread pool and probably I/O completion port to regulate it. The main requirement is that a windows service manage the HTTP requests for a number of reasons. An example of one would be that a client session spans many requests and continuity must be maintained. Another would be that the ISAPI Dll will be in the IIS address space and so it's code will be lean and very carefully implemented. The extensive processing in the Windows service may get unruly for the duration of the lengthy development. If the service crashes it will not take out IIS. Anyway, the remaining decision is how to have these two processes communicate. We have talked about pipes, tcp, global memory and even a single pipe with multiplexed data ala FastCGI. Would love to hear anyones experience with a decision like this.

  • What are the best practices for service accounts?

    - by LockeCJ
    We're running several services in our company using a shared domain account. Unfortunately, the credentials for this account are widely distributed and being used frequently for both service and non-service purposes. This has led to a situation where it is possible that the services will be temporarily down due to this shared account being locked. Obviously, this situation needs to change.

My questions is this: Should we be setting up the service accounts differently than other domain accounts, and if we do, how do we manage those accounts.
