RE: EM12c incidents when restarting OMS

We are on 12.1.0.3 which I think is the latest version, but I could be wrong about that. I had already completed steps 1 and 2. It is step 2 that is firing off all the incidents for us.

The alert messages all seem to be tied to the agents (not the agent on the oms). They fire "Agent is unable to communicate with the OMS. (REASON = Agent is Unreachable)". That fires for all the servers we have agents on. Then we get a flood of Target incidents (agent, host, listener,Instance) which we have set to trigger on an Agent unreachable Availability check. Once we start the OMS back up, everything then clears out

I will check that MOS note you referenced

Thanks,
Mike

Subject: RE: EM12c incidents when restarting OMS

Hi Mike,

I used to have a similar issue. Could you please confirm which version/release of EM12c you use?

My fix for this was as follows:

1. Unsubscribe from the out-of-the-box incident rules in the EM12c. The out-of-the-box rules (at least on EM12c R1, I have not checked recently) include notifications for EM12c components (WebLogic domains and servers and so on) that I do not wish to receive.
2. Create custom incident rules for all the targets, target types and incident categories for which you DO wish to be notified (eg Database System, Listener, MySQL Instance, Agent) and subscribe to these instead.
3. Configure OOB monitoring for the oracle_emrep OMS and Repository target, per MOS note 1472854.1.

I haven't seen an actual crash in my EM12c environment for which I would have needed notification since R1+BP1. Using this setup, and a script that shuts down my central agent along with the OMS when I need to bounce EM12c, I do not receive any notifications at all from a planned bounce. I still monitor the repository database target just like my other non-OEM databases, but I do not monitor any of the internal EM12c components. This may be more complicated if your environment includes other WebLogic targets (mine doesn't, so I ignore them all), but you can create target groups to include/exclude specific targets from notifications as needed.

Hello,

Does anyone else who uses 12c cloud control have the issue where you get a ton of incidents firing off if you shutdown the OMS?

We have incident notifications setup related to the availability of targets, and whenever we try to shutdown the OMS we get a ton of pages and emails as a result of these. Was thinking there has to be a way to prevent them from kicking off, but haven't found a good answer yet.

Does anyone know a command or workaround for this?

Thanks in advance for the help
Mike
