Install .NET agent after patching dynaTrace to 5.5.0.5562
I have patched a dynaTrace installation to 5.5.0.5562 and try to install a new .NET agent, but following the script will try to download from: https://downloads.compuwareapm.com/services/AgentDownload.aspx?version=5.5.0.5562&os=windows&arch=x64&techtype=java_net telling:
The requested agent was not found.Please visit the download page and download the agent manually.
Going to the download page I can not see any Windows agents for this patched version, only the "GA" installed version.
The version on the download page is the old "GA" version.
What will happen if we install this old version?
Will it be upgraded automatically by the DT server when defining it in DT? If yes, do we have to restart the .Net service several times?
Why can't we just download the correct version directly from the web our self?

Hi
dynaTrace provides automatic agent updates. When an agent connects to dynaTrace it will automatically get the latest version. So - there is actually no need to re-install or update an agent with an installer. All you need to do is restart your application so that the agent can update itself during the startup phase.
I will check on the download link though. The link should work. But - again - in your case you just need to restart your app

Thank you Andreas!
Does it mean we need two restarts of the application (One after install GA and one after update)? Or will the agent check it's version - update and then start? If so down time for the application will be restart in addition to time to update agent?

The agent updates itself during startup before it becomes active. So - after you have patched your dynaTrace server all you need to do is to either start the .NET Application for the first time or restart it if itis already running with an agent. In both cases the Agent will first check if there is a new version available, it will download it and then continue with the instrumentation of the application using the new version.
If you have a running dynatrace installation and you install a FixPack you shoudl really only need ONE restart of your application
Thanks again for quick feedback!
Is it the DT server or collector that holds the program code? Normally you install a local collector to minimize the affect of link caracteristics, but the server can be remote.... I'm thinking of the time it will take to update the agent via a WAN link...
What is a typical size of a patch? Is it the same as the total size of installing the agent?
What is the size for 5.5 and 5.6 agents?
As I read your feedback this is a general behavior for all kind of agents. Correct?
-Tore
The size of the FixPack that you install on the dynaTrace Server really depends on the changes that are included in that fix. After you have installed the FixPack and you have a first agent connecting to the collector the Collector will download any newer version of the Agent from the server and then cache it locally on the Collector. I think the full size of the whole agent package is about 80-90MB (that includes Java/.NET/Web Server agents). So - that package needs to be downloaded by the Collector from the server. Then it is just a "local" distribution to the locally connected agents.
The "automatic update" behavior is also true FOR ALL types of agents
