Overview
Oracle Exadata Database Machine consists of several components
such as Compute nodes, Storage Cells, ILOM, Infiniband Switches, Cisco Switch
and PDUs. So we need a tool that can manage all these components from one
single console. Oracle Enterprise manager Cloud Control is the recommended best
practices for monitoring and managing Exadata Database machine. Once the
Exadata database Machine is installed the next step is enable monitoring for it.
The following Exadata components can be monitored and managed by
OEM:
- Compute Nodes
- Storage Cells
- Infiniband Switches
- Cisco Switches
- Power Distribution Units
- KVM
The first step in monitoring and managing Exadata using OEM is to
install the EM Agent. You can install EM Agent in several ways, such as:
- Using EM Kit Method
- Using the Agent push method
- Using an RPM file
- Using the AgentPull script
- Using the AgentDeploy script
In this article we will demonstrate how to Install EM Agent on
Exadata using Agent Push method using OEM 13c. Agent Software is installed only
on Compute nodes.
Environment Details
Here we will be installing EM Agent on a Exadata V2 Full Rack
consists of:
- 8 Compute Nodes
- 14 Storage Cells
- 3 Infiniband Switches
- 1 Cisco Switches
- 2 Power Distribution Units
- 1 KVM
Procedure to Install EM Agent on Exadata Compute nodes
Enter the OEM 13c URL into the web browser and
hit enter
Enter the SYSMAN Credentials or any other user
that have necessary permissions to Install Agent software
We are on the OEM 13c Home page now
From the Home page, click on Setup à
Add Target à
Add Targets manually
Click on Install Agent on Host
On this page, click on the +Add button to add the
Host targets
Enter all fully qualified Hostnames (8 compute
nodes) and for Platform “Same for All Hosts” and click next
Enter the Installation Base Directory.
The instance base directory will be
populated automatically for you.
Click on the + symbol on the Named
credentials and enter oracle user and its password.
Click on the + symbol on the Root credentials line and
enter root user and its password.
Click next
Click Deploy Agent
The Agent Installation process started
Initialization in progress
The Remote prerequisite check shows warning.
This can be ignored as oracle user doesn’t have sudo permissions to run the
root.sh script. The can be ran at the end.
Click Continue à Continue, All Hosts
Installation process completed. Click Done.
Connect to Exadata compute node 1 and run the root.sh
script as follows:
[root@dm01db01 ~]# dcli -g dbs_group -l root
‘/u01/app/oracle/product/Agent13c/agent_13.2.0.0.0/root.sh’
dm01db01: Finished product-specific root actions.
dm01db01: /etc exist
dm01db02: Finished product-specific root actions.
dm01db02: /etc exist
dm01db03: Finished product-specific root actions.
dm01db03: /etc exist
dm01db04: Finished product-specific root actions.
dm01db04: /etc exist
dm01db05: Finished product-specific root actions.
dm01db05: /etc exist
dm01db06: Finished product-specific root actions.
dm01db06: /etc exist
dm01db07: Finished product-specific root actions.
dm01db07: /etc exist
dm01db08: Finished product-specific root actions.
dm01db08: /etc exist
Verify Agent is running on Exadata compute nodes.
