How to refresh the application files without stopping the AOS ?

(0) ShareShare
ReportReport
Posted on by Nerazzuro 75

Hi,

I am using Dynamics AX 2009, and I am facing three problems:

1- The code modifications in one AOS service are not visible from the users connected to other services

2- The AOD and ALD files modification datetime is not updated automatically

3- The AOS services are consuming much memory

These problems are solved when I restart the AOS services. I guess that it is because of the server caching, so when the AOS is stopped it updates the application files with the modifications stored in the cache memory.

How can I refresh these files automatically and frequently without stopping AX ? I tried "Refresh AOS", "Refresh Dictionary" and "Refresh Data" from the Development Tools but it didn't work.

Thanks in advance.

    The Refresh AOS/Dictionary/Data menu items all run on client. You can find the menu items in the AOT and set them to run on server (SysFlush* under the action menu items). However, the AOS should flush its cache at midnight every day automatically. You can see that in the event log.

    Hi Joris,

    Thank you for your response !  Running the SysFlush from the AOS effectively has resolved my first problem. But the application files (*.ald and *.aod) are still not updated and the AOS services keep the cache and doesn't free their memory.

    It's also important because sometimes I have to deliver labels from an AX environment to another (during the day) without stopping the application.

    You cannot update the files while the AOS is running. Even in AX 2012, where the AOD files no longer exist and all the code is stored in SQL, you still have to restart the AOS (although there are some ways to minimize downtime) when replacing layers or labels.

    As far as labels go, you can try moving code with labels inside the XPO files. I personally think XPO moves to a production environment should be avoided though (see my rant at daxmusings.blogspot.com/.../deploying-your-ax-2012-code.html ). A little downtime should be possible. I always compare AX code updates to windows updates. You are updating a critical system in your organization. Windows updates require reboots as well. And even if they don't, you are probably not going to be running updates during the day when people are working on that server. And you're also not moving C++ code into your server for an update, you're replacing compiled DLLs.

    Hi,

    Thank you very much. I really appreciate your comparison between the AX updates and the Windows ones.
