Question 30/72
You configuring has two half racks, one with high capacity disks and other with high performance disks and high capacity expansion half rack.
There are two RAC clusters, one on each half rack, which have separate storage grids, each consisting of some of the storage servers in the configuration.
You are planning your deployment of Enterprise Manager to monitor all the components of this multi-rack Database Machine, and must provide for high availability of the monitoring infrastructure.
If the host running the agent which has database machine targets bound to it fails, the monitoring of these targets must be another agent.
Which two are true regarding the configuration used to support this?

Which two are true regarding the configuration used to support this?
Correct Answer: A,D
Explanation/Reference:
Note:
* Instructions for configuring a high availability solution for the Exadata Storage cell or any other Exadata plug-in are documented in the Oracle Database Machine Monitoring Best Practices (Doc ID 1110675.1) document located in My Oracle Support
* High Availability for Plug-Ins
Normally a plug-in target is bound to a specific agent
If the agent is down the target cannot be monitored
A procedure exists to facilitate target failover to a secondary agent
* The Enterprise Manager agent must be deployed to all compute nodes of the Exadata Database Machine.
* The Oracle ILOM plug-in monitors the Oracle ILOM service processor in a compute node for hardware events and records sensor data to the Oracle Enterprise Manager Repository.
The ILOM plug-in is deployed to the Enterprise Manager (EM) Agent on the first compute node in an Oracle Database Machine, and only that EM agent communicates with the EM Management Server and Repository for all ILOM database server service processors in the Oracle Database Machine.
* OEM Agent and Exadata Plug-ins
1. OEM Agent and Plug-Ins
are deployed under Oracle
Home
2. Agent incorporates
additional functionality in
Plug-In
3. Agent and Plug-in
DB Server on Exadata DBM
3. Agent and Plug-in
communicates with
Storage Server
4. Plug-Ins are available for
monitoring all Exadata
hardware components
5. OEM Agent communicates
with the OEM
