Subject [jira] [Commented] (ACE-520) Only available serverurl gets blacklisted, broke our application
Date Thu, 28 Jan 2016 13:40:39 GMT

J.W. Janssen commented on ACE-520:
----------------------------------

There is an option to disable the checking of URLs: {{agent.discovery.checking}}, by default
it is enabled, but that would only make sense if there are actually more server URLs to check.
We should probably only check URLs if there are more URLs provided.

> We only have one ACE server running and it became unavailable for an extended period
due to a maintenance window. All of our client applications (running the agent bundle) blacklisted
the server address and failed to detect when the server came back online. Also, immediately
following the agent blacklisting the server, our application's DS services silently stopped
working (no indication they had been deactivated, just stopped communicating with our servers).
We had to manually restart the application at all our customer locations to get them working
again.
> The server and agent were taken from the latest release, 2.0.1, and we're using Felix
release 5.0.0. The agent bundle is loaded from the Felix auto deploy directory. Here are the
Felix and ACE settings we use:
> Felix:
> felix.auto.deploy.action=install,start,update
> # DEBUG level logging
> felix.log.level=4
> ACE:
> agent.identification.agentid=<removed>
> agent.discovery.serverurls=<removed>
> agent.controller.syncinterval=420
> agent.logging.level=DEBUG
