Mass Agent Deployments
This is just a short update on the prerequisites, especially firewall port requirements that you will need to ensure agent deployments in Enterprise Manager Grid Control work correctly. This is not well documented in the install manual. Chapter 9 of the advanced installation guide contains the basic requirements.
It however misses out some basics. This method of deployment does the following:
1) ssh and ping the target and run some prerequisite checks.
2) scp the install across
3) ssh across and run the install
4) do target discovery
5) setup secure comms.
Consequently the following needs to be allowed through your firewalls.
ssh, ping, oms to agent comms, agent to oms comms on both the secure and unsecured upload ports.
In addition we found that you’ll need to edit userPaths.properties in $EM_DOMAIN/sysman/prob/resources for the correct Linux paths to sudo and rsh etc to be picked up.
