HowTo: Force re-evaluation of Policy Violations in OEM Grid Control

Don't you hate when you fix a Security/Policy Violation in OEM and it won't re-evaluate it for another 24 hours?

Well there's 2 things you can try:

1. Apply your Monitoring Template to the object (this works especially well for Hosts), this will force a re-evaluation and clear outstanding alerts
2. Use an undocumented parameter for the EM Agent (10.2.0.1+) "emctl clearstate agent". This will cause the Agent to re-evaluate the instances on it's host - note: this can take a couple of hours to run and update in the background!
