Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c
- by S Stelting
Oracle
Enterprise Manager Ops Center 12c recently released an upgrade for
Solaris Agent Controllers. In this week's blog post, we'll show you
how to upgrade agent controllers.
Detailed
instructions about upgrading Agent Controllers are available in the
product documentation here.
This blog post uses an Enterprise Controller which is configured for
connected mode operation. If you'd like to apply the agent update in
a disconnected installation, additional instructions are available
here.
Step
1: Download Agent Controller Updates
With a
connected mode Ops Center installation, you can check for product
updates at any time by selecting the Enterprise Controller from the
left-hand Administration navigation tab.
Select
the right-hand Action link “Ops Center Downloads” to open a
pop-up dialog displaying any new product updates. In this example,
the Enterprise Controller has already been upgraded to the latest
version (Update 1, also shown as build version 2076) so only the
Agent Controller updates will appear.
There
are three updates available: one for Solaris 10 X86, one for Solaris
8-10 SPARC, and one for all versions of Solaris 11. Note that the
last update in the screen shot is the Solaris 11 update; for details
on any of the downloads, place your mouse over the information icon
under the details column for a pop-up text region.
Select
the software to download and click the Next button to display the Ops
Center license agreement.
Review
and click the check box to accept the license agreement, then click
the Next button to begin downloading the software.
The
status screen shows the current download status. If desired, you can
perform the downloads as a background job. Simply click the check
box, then click the next button to proceed to the summary screen.
The
summary screen shows the updates to be downloaded as well as the
current status. Clicking the Finish button will close the dialog and
return to the Browser UI. The download job will continue to run in
Ops Center and progress can still be viewed from the jobs menu at the
bottom of the browser window.
Step
2: Check the Version of Existing Agent Controllers
After
the download job completes, you can check the availability of agent
updates as well as the current versions of your Agent Controllers
from the left-hand Assets navigation tab.
Select
“Operating Systems” from the pull-down tab lets to display only
OS assets. Next, select “Solaris” in the left-hand tab to display
the Solaris assets. Finally, select the Summary tab in the center
display panel to show which versions of agent controllers are
installed in your data center.
Notice
that a few of the OS assets are not displayed in the Agent
Controllers tab. Ops Center will not display OS instances which do
not have an Agent Controller installation. This includes Enterprise
Controllers and Proxy Controllers (unless the agent has been
activated on the OS instance) and and OS instances using agentless
management.
For
Agent Controllers which support an update, the version of agent
software (in this example, 2083) appears to the right of the
currently installed version.
Step
3: Upgrade Your Agent Controllers
If
desired, you can upgrade agent controllers from the previous screen
by selecting the desired systems and clicking the upgrade button.
Alternatively, you can click the link “Upgrade All Agent
Controllers” in the right-hand Actions menu:
In
either case, a pop-up dialog lets you start the upgrade process. The
first screen in the dialog lets you choose the upgrade method:
Ops
Center provides three ways to upgrade agent controllers:
Automatic
Upgrade: If Agent Controllers are running on all assets, Ops
Center can automatically upgrade the software to the latest version
without requiring any login credentials to the system
SSH
using a single set of credentials: If all assets use the same
login credentials, you can apply a single set to all assets for the
upgrade process. The log-in credentials are the same ones used for
asset discovery and management, which are stored in the Plan
Management navigation tab under Credentials.
SSH
using individual credentials: If assets use different login
credentials, you can select a different set for each asset.
After
selecting the upgrade method, click the Next button to proceed to the
summary screen. Click the Finish button to close the pop-up dialog
and start the upgrade job for the agent controllers.
The
upgrade job runs a series of tasks in parallel, and will upgrade all
agents which have been selected. Once the job completes, the OS instances in your
data center will be upgraded and running the latest version of Agent
Controller software.
