How to identified how much Heap Size OMS 12c Agent needs?

edited Jul 5, 2016 5:01AM in Database Administration (MOSC) 1 commentAnswered

Hi all,

I'm a DBA supporting multiple servers in my company. Lately I've been getting Heap Size memory errors on some of the OMS Agents in our servers. I've increase from 128M to 512M and now to 1024M, so far it's quite stable with this sizing. What I would want to know is why does the agent which was working fine all the while starts throwing these error messages? How to identify what the agent is doing to require so much heap size? Also is there any formula to calculate how much heap size should we allocate for the agents?

Howdy, Stranger!
