404 Error in IIS for .net 6 applicqion while using IBM MQ

  • 1.  404 Error in IIS for .net 6 applicqion while using IBM MQ

    Posted Mon February 26, 2024 12:32 PM

    Hi,

    I am using IBM MQ nuget package IBMXMSDotnetClient 9.3.4.1 (XMS.net). Visual Studio 2022 and .Net 6.

    My application is running fine in Visual Studio 2022 and as a Console application. However after launching the swagger in IIS I am getting below error - 

    I am not using any MQClient.ini as its not required by application.

    Application '/LM/W3SVC/6/ROOT' with physical root 'C:\inetpub\wwwroot\.Project.API\' hit unexpected managed exception, exception code = '0xe0434352'. First 30KB characters of captured stdout and stderr logs:
    'dspmqver' is not recognized as an internal or external command,
    operable program or batch file.

    Any help appreciated.

    > 'dspmqver' is not recognized as an internal or external command,

    Did you install the MQ Client software on that server? If so, when running under IIS, does the application have permission to access the executables of MQ?

    Ensure that the IBM MQ client is properly installed on the server running IIS. Verify that the environment variables are set correctly, including PATH. Confirm that necessary DLLs are accessible by the application. Check if MQClient.ini is required despite stating otherwise. Ensure proper permissions for the application to access required directories. Review configuration settings for any discrepancies between the console application and IIS deployment. Apart from this, when I click on winch's post in this website, I often see this 404 error. But this link often times when I click on this link after some time or after a day, this 404 error has ended. I have come to know that this error is caused by the website and not by Google.

    Use the setmqenv command to initialize the current command environment before executing IBM MQ related commands

    IBM MQ is installed and IIS user has full access to it

    C:\> dir /b /s C:\setmqenv.cmd is giving error - File Not Found

    Ok. That says you don't have MQ installed on your C: drive. You say MQ is installed then which drive did you or the MQAdmin install MQ on?

    Here's my setup where IBM MQ v9.3 is installed on my D: drive.

    C:\>dir /b /s C:\setmqenv.cmd
    File Not Found

    C:\>dir /b /s D:\setmqenv.cmd
    D:\Program Files\IBM\MQ\bin\setmqenv.cmd

    If your goal is simply to run the dspmqver command then why don't you just add the MQ bin or bin64 directory to the System's PATH environment variable. To run the 64-bit version of dspmqver, just add the path to bin64 PATH environment variable and in my case it would be "D:\Program Files\IBM\MQ\bin64".

    i.e.

    C:\>dir /b /s D:\dspmqver.exe
    D:\Program Files\IBM\MQ\bin\dspmqver.exe
    D:\Program Files\IBM\MQ\bin64\dspmqver.exe

    later

    Is MQ installed on the C: drive?  From the output generated by this command, I would suspect not.

    C:\> dir /b /s C:\setmqenv.cmd

    If, for example, it is on the D: drive, replace the C: in the dir command with the drive letter where MQ is installed.  If you aren't sure, you can provide multiple drive letters on the dir command.  For example:

    C:\> dir /b /s C:\setmqenv.cmd D:\setmqenv.cmd E:\setmqenv.cmd F:\setmqenv.cmd

    You can specify as many drive letters as exist on your system.  You will get a "File not found" message for each drive letter where the setmqenv.cmd file is not present.

    Hello Shoeb Mirza,

    Shoeb Mirza sent me a private message with the following:

    IBM MQ is installed at below location - However I don't see bin or bin64 or client.ini file. Please help. In my code I am using nuget package 9.3.4.1 of IBM MQ. In visual studio my code is working and I can post message successfully.

    Plus a screenshot of his MQ Explorer directory tree.

    First off, MQ Explorer is not IBM MQ Server or Client install. MQ Explorer is an MQAdmin tool to create/alter/delete MQ objects.

    I, plus another person, asked you if you installed the IBM MQ Client. You said yes it was but clearly it is not installed. You downloaded a single DLL (IBMXMSDotnetClient 9.3.4.1) from NuGet. That is NOT the IBM MQ Client. Your code is trying to run/execute dspmqver program. If you checked where you put the DLL then you would have seen that it was missing.

    If you didn't know what we were referring to when we asked you about IBM MQ Client being installed then you should have said you didn't understand what we were referring to.

    The IBM MQ Client v9.3 can be downloaded from: https://ibm.biz/mq93clients

    The latest release of IBM MQ Client is v9.3.5.0, and for Windows 64, you need to select the one labelled "9.3.5.0-IBM-MQC-Win64 ". You will download it then run the installer to install it. Now you will have the IBM MQ Client installed which includes the program dspmqver.

    later

    As you seem to be using mqclient.ini, please make sure that you are set to be using MQAUTHENTICATION_USE_MQCSP or the equivalent for .NET.

    Depending on the package there was some obscure note that said if the authentication is not made via the MQCSP method the userid could get truncated at (don't remember if it was 8 or 12). I've seen it happen in Java where you were not able to authenticate the user id as it got truncated. In non MQCSP mode the password may also get truncated (i believe if longer as 16 chars?)

    Hope it helps.
