XppIL folder is empty after Restart AOS Service

Posted on by VasanthArivali 1,602

Hi,

During my fix deployment on Production suddenly AOS service went down (say as CRASHED). I tried to restart and It was at 'STARTING' state for a long time without any progress. Event Viewer didn't log any info and stops at one particular point which saying 'could not load assembly 'VendInvoiceDocumentReport.BusinessLogic' or one of its dependencies'. SQL Activity Monitor didn't show any Blocking transactions.

I have killed the current AOS Service PID via command prompt and tried to start again and faced the same issue. Then backup by rename the original XppIL folder and created new XppIL folder. Then the service has been started but no Files / Folder generated in that. 

I have reset the GUID for AOS via SQL by update #EmptyGUID in SysSQMSettings table, they tried. AOS started by XppIL folder still empty.

My user Id is local admin and I have done the same(new XppIL foder) in my last deployment without any issues. Due to this AOS crash, I don't know what went wrong and where.

Any help / suggestions?

    How did you do the deployment? Through a modelstore import?

    Hi Martin,

    No, via Project XPO.

    That project has only 2 objects ( a table and a class) both compiled with no errors. Then I compiled the project, immediately system went to not responsive and AOS got crashed.

    FYI, In our PROD env , we have only one AOS and that is enabled as batch server as well. I never unchecked any deployments and till last time, all my deployments are done without any issues.

    That's not how deployment should be done. Importing an .xpo is an equivalent of writing code in production. You've also created a ne state of the application that you didn't test before. The right approach is testing an application in a test environment and then deploying the whole application to production, therefore you deploy what you tested

    Also, compiling individual objects isn't enough - you should compile the whole application and build full CIL (if X++ compilation succeeded). Please try it. Also, because you've added a table, you'll have to synchronize the database.

    Yes Martin, I agree on that. But here they following this from the system went live. I have joined recently and continue the same. I have also recommended to have test system but not still not implemented. I will try to change the deployment process as you said.

    On the deployment part, I will do Full Synch & CIL after the XPO deployment but not compile.

    On the issue, When I do project compile AOS down. To bring back I created new XppIL folder and started but no files but AOS running. If I roll back to original folder AOS not even Running it was hanged at 'Starting' state. In this kind of situation, how to bring back the AOS with XppIL files.

    FYI, I didn't truncated XppAssembly table after crash happened

    Don't compile a project - always compile the whole application after you deploy code (unless you switch to a reasonable deployment process). Yes, compilation takes time, but that's the price you pay for not deploying an already compiled application.

    I can only compile application if AOS is running, I will follow the procedure in the future deployments.

    Here problem is AOS in 'Starting' state with Orig XppIL folder, with new XppIL folder it is 'Running' state but no files inside the folder.

    After you compile the application and generate full CIL, files will be added to the XppIL folder.

    Martin,

    I cannot open AX client if there is no files in the folder.

    I have the Original Folder backup, Shall I copy that files to the new folder to open the application?

    The right approach is testing an application in a test environment and then deploying the whole application to production, therefore you deploy what you tested - Deploying the Model Store right?

    you should compile the whole application - can do parallel compile?

    Yes, if things went wrong, restoring the original state is a good idea.

    You could deploy models, but only modelstore deployment guarantees that you get exactly the same version of application. Model deployment also require compilation; modelstore deployment doesn't.

    Yes, you can use axbuild for parallel compilation of X++.
